Time for a ChangeJanuary is the season for a change for many people. Getting a new job or hiring new employees is normal in January. It’s no different for the ACR Journal. Our top two news stories online are about people who have changed jobs.

It is also show season. The AHR Expo in the USA will have happened, and The ACR Show in Birmingham will be a matter of days away by the time you read this. Later this year, Chillventa is here again. All of this means we should see some interesting new solutions for the heating, ventilation, AC and refrigeration market.

However, the third most popular article online in January is about an old favourite – F-Gas. This topic continues to drive much of the new business in the market.

Connected to that is energy efficiency. Lowering energy costs is front and centre of many new business deals. But, I often hear that it is challenging to get the message about considering not just the capital costs but the operational costs of a solution to more senior people in a customers’ business.

Given that many businesses rely on refrigeration or air conditioning for their success, is it not time that people in charge of ‘cooling’ in those companies sat on the board? Cooling is as important as IT in many companies.

COOLSUREDOORS KEEPSCOMMISSARY COOL AND EFFICIENT

coolsuredoors, the Bedforshire-based refrigerated cabinet doors manufacturer, helped the US Forces Commissary at RAF Lakenheath, become more energy efficient recently.

Working with Fridge Systems, who commissioned the project, coolsuredoors refursbished the refrigerated cabinet doors on 21 meat and dairy units in the store. The team had to replace 90 doors over five nights to help the Commissary make shopping easier for customers and save energy.

Michael Tucker, managing director, coolsuredoors comments,

“The refurbishment and installation of the doors at RAF Lakenheath’s Commissary had to be carried out in an

extremely tight time-frame for the client. This was achieved by our precise project management and planning.

“The addition of Universal doors and LED lights to the refrigerated cabinets has created a warmer, more inviting environment for the shoppers. The retailer is also extremely pleased with the reduction in energy loss and the new look of the store. Overall we have delivered a cost-effective and environmentally friendly solution to suit the updated facility.”

The coolsuredoors system allows shopper to easily access produce in the cabinets, and also allowing staff to restock shelves quickly. The doors cut down the energy use of the chiller cabinets.

REFRIGERANTS:BITZER APPROVES R404A AND R507A REPLACEMENTS FOR COMPRESSORS

Bitzer, the German compressor manufacturer, has approved its two-stage reciprocating compressors for use with new, low GWP refrigerants.

The company announced that it has approved R448A and R449A, the low global warming potential alternative refrigerants to R404A and R507A, for use with its compressors. Each of the alternative refrigerants has a GWP below 1400, which makes them ideal for low temperature applications. All Bitzer two-stage reciprocating compressors now work with new alternatives as well as with thermostatic expansion valves.

The approval came after Bitzer modified its compressors to work with refrigerants R448A and R449A. They have global warming potentials of 1386 and 1397, respectively. R404A has a GWP of 3922 and its use will be banned in stationary areas after 2020 because of the F-Gas regulations.

Bitzer’s tests, using the alternatives to R404A and R507A show that its modified compressors work perfectly well with R448A and R449A, and can be applied in ‘areas are practically identical to those of R407F’, according to the company’s statement.

R448A and R449A are ‘transitional refrigerants’ which help to bridge the gap as industry moves towards using low GWP refrigerants entirely.

VRF: BOSCH ENTERS THE MARKETBoschCommercial and Industrial, theGerman-ownedheating and hotwater equipmentmanufacturer, enteredtheUK air conditioningmarket in Januarywith the newsthat it has a new variable refrigerant flow (VRF) range.Its VRF systems deliver simultaneous heating and cooling

for domestic and commercial properties.The Bosch Climate 5000 VRF systems comes in three

types, namely the SDCS series, its inverter heat pumprange; the RDCI series, an all DC inverter heat recoverysystem; and theMDCI series, the company’smini VRF heatpump, which is suitable for small domestic, commercial andsmall retail properties.Bosch is confident that its VRF range is efficient and easily

controllable through its Bosch VRF IntelligentManager(BVIM) solution.GeoffHobbs, Business Development Director at Bosch

Commercial and Industrial said:“Consultants, contractors, architects and specifiers

within the building services industry are increasingly facedwith the challenge of recommending and installing flexibleheating and hot water systemswith the ability tomaximiseefficiency.With this inmind, we’ve taken the decision tointroduce a VRF systemwhich offersmaximumheating andcooling comfort efficiently, and on a large scale.”It is a boldmove by Bosch to enter the UKmarket. It

has a strong brand name in the heating sector through itsWorcester Bosch business where it is well established. Theair conditioningmarket has two dominantmanufacturerswith several companies competing hard to be number threein the UK.However, the company has deep expertise in developing

a strong partner network and using high profilemarketingto grow its business. The new player in the air conditioningmarket will intensify the competitionwhichwill be good forend users.

This length of timemight seemdifficult to defend in a timewhen refrigerant requirements

are changing very rapidly, butthe task has been complex andrequired the balancing of numerouscompeting requests for change(or in some cases no change). It isdifficult to see how the process couldbe significantly shortenedwithoutthoroughly exploring the technicalimplications of all viewpoints.

Too complicated and stringent?The current versionmight be consideredby some to be still too complicated andnot 100% suitable for all circumstances.In particular the increased use offlammable refrigerants, whetherthey are class A3 hydrocarbons orclass A2LHFOs, is likely to lead to aneed for further refinements to thestandard as “real-world” experience of

Inparticular thewideruseofA2Ls in supermarkets, chillers andothersmall tomedium-sizedsystemswill lead tofurtherworkby the International draftingteamstomake thestandard iseasy tousewhile still ensuringhighsafety levels.

Will it mean systemdesign changes?Theway inwhich companies do theirsystemdesignwill not fundamentallychangewith this revision of EN378however. If designers choose to usemildlyflammable refrigerants, theymust still

follow all of the legal and safety standardrequirements associatedwith flammability.This goes beyond the scope of

EN378, which is not harmonizedwiththose regulations. It does notmeanthat all electrical equipment needs tobe “flameproof” of the type found inpetrochemical plant, but it doesmeanthat if the safety data sheet for therefrigerant has the hazard phraseH220 orH221 then a risk assessment conformingto the requirements of DSEARmust becompleted andmust covermaintenanceand service activity as well as normaloperation and standstill.Aguidance noteon the useofDSEAR for

ammonia systems is being prepared by theFoodStorage andDistribution Federationwith input from the IOR, and a version ofthis for hydrocarbon andpossibly forHFOrefrigerantsmaybe called for in the future.Themain issues that designersmayfind

with this revision of the European safetystandard donot liewith the text of thestandard itself, but in theother regulationswhichwill apply if companies areencouragedby the introduction of the newflammability class to adopt the new “lowerflammability” refrigerants. This does notmake their use impossible, but it is an extralayer of difficulty to beovercome.

Find out more at theIoR Annual ConferenceThose interested in finding outmoreabout changes in the proposed newstandard can attend amore detailedtalk being given by the IORTechnicalCommittee Chairman, Andy Pearson,as part of the IORAnnual Conferenceon 18th February 2016 in Birmingham.The revised standard itself is still goingthrough an international approvalsprocess and at the earliest is expected tobe available for use in spring 2016.

It was reported at the IOR Technical Committee this month that after seven years ofdiscussion and debate the process for the updating of EN378 is nearly complete.

EPEE– theEuropeanPartnership forEnergyandtheEnvironment is conductingauseful studyonhowthe regulation isbeing implementedacrossMember

Statesandthis is throwingupanumberof issues,whichwill be fedback to theEuropeanCommission.

The latest figures available from the Environment Agencyon the numbers of individuals having achieved the requiredminimumqualifications and companies including sole tradersobtaining their F Gas Certifications are encouraging:

In themeantime the EuropeanCommission published threenew implementing Regulations relevant to air conditioning,refrigeration and heat pump sectors, in November 2015.

LabellingThe first of these outlined the format for new labels forproducts and equipment containing fluorinated greenhousegases, whichmust be in place from1st January 2017. Knownas Implementing regulation (EU) 2-015/2068, this replacesRegulation (EC) No 1494/2007 and article 12 (14) of Regulation(EC) No 842/2006. It defines the exact wording of theinformation to be included on labels referred to in Article 12(1) of Regulation (EU) No 517/2014 and sets out requirementsensuring visibility and readability of such labels with regardsto their layout and replacement. New labelling requirementswill apply to all products containing fluorinated greenhousegases including equipment and containers, drums, road andrail tankers from 1st January 2017. Thewording is similar toexisting labels but includes additional requirements such asCO2 equivalent values.

Harmonisation of certification across differentMember StatesThe second sets out the format forMember States to notifythe Commission of any additional training and certificationprogrammes. Known as Implementing Regulation (EU)

₀ Nearly 35,000 individuals have obtained full certification toCity & Guilds Cat. 1/CITB J11

₀ 530 are qualified to work only on equipment under 3kg of HFC refrigerant -City & Guilds Cat. 2/CITB J12

₀ Recovery of end of life equipment only - City & Guilds Cat. 3/CITB J13 – 1,000₀ Leak checking only - City & Guilds Cat. 4/CITB J14 – 2,105₀ Company/Sole Trader F Gas Certifications are now just under 7,000

F-GasDevelopmentsIt appears to have been fairly quiet on the F Gas Regulation front in recent months

but there have been some developments behind the scenes.

2015/2065, this replaces article 10 (13) of Regulation (EC)No 842/2006 and repeals Commission Regulation (EC) No308/2008.It specifies essential information required to allow the

authentication of a certificate or attestation to ensure itcomplies with theminimum requirements. This should bereassuring for those employing individuals who have gainedtheir certificate in anotherMember State.

Minimum requirements for individual certificatioNThe third updates theminimum requirements and conditionsfor the certification of technicians and companies in thestationary air conditioning, refrigeration, heat pumpequipment and extends these to refrigerated trucks andtrailers containing fluorinated greenhouse gases. This isImplementing Regulation (EU) 2015/2067, and replaces Article10 (12) of Regulation (EC) No 842/2006 and also repealsRegulation (EC) No. 303/2008.It clarifies new obligations for refrigerated trucks and

trailers, concerning certification of companies and individuals,that have now been included in the newRegulation. It alsoformalises the requirements for the content of certificationprogrammes to contain information on relevant technologiesto replace or reduce the use of fluorinated greenhouse gases.This new requirement was included in UK certifications from

January 215, but the Implementing Regulation applies onlyfrom 1st July 2017 to allow otherMember States time to adapttheir existing certification programmes. It should be notedthat existing Certificates issued under the original Regulation842/2006 remain valid and re-certification is not required,unless the certificate issuer has put an expiry date on it.If youwish to download copies of the newRegulations there

are links on the www.acrib.org.ukwebsite, where the latestinformation on FGas is added regularly.ACRIB is participating in the implementation study being

conducted by EPEE (mentioned above) andwould be pleasedto feedback any issues and concerns that individuals orcompanies implicated by the new FGas Regulationmay have.All such issues and concerns are also sharedwith DEFRA andthe Environment Agency as deemed appropriate.We are also advised that DEFRA is proposing to host an F

Gas stakeholdermeeting inMarch to keep industry informed ofthe latest developments. ACRIBwill report on the outcomes ofthatmeeting in the future.

The factories that produce our air conditioningsystems have some of themost robust qualitycontrol procedures in the industry, so if we do ever

get products returned from a job, then you can be surethat we investigate thoroughly to identify any issues.Fromanalysis of returns, it would appear that occasionallywe

comeacross an engineerwhohas simply forgotten the basics andnot taken adequate care of any brazing on the system.

I don’t believe this is amajor problem throughout the industry,especially looking at the numerous engineers I comeacross inmyrole as a trainer, but for us asmanufacturers, andperhapsmoreimportantly, for the customers of the air conditioning systemsbeing installed, it can lead to added costs anddelays.With legislation such as F-Gas now in place, this should also

be themost basic thingwe all look at, if only tomake sure thesystems are installed to run as efficiently as designed.

It sounds simple and youwill forgiveme appearing to teacheveryone how to ‘suck eggs’.

Ben Bartle-Ross, technical trainer at Mitsubishi Electric asks forfeedback on installer support for controls

M I T S U B I S H I E L E C T R I C12FEBRUARY 2016

A BRAZEN REMINDERIt’s therefore worth reminding ourselves of one of the first thingswe are all taught – Use OFN!

₀ Check and double check the penetration of the brazingbefore pressure testing the full system (Remembercutting through the pipes during training and whatyou were looking for?).

₀ Always use oxygen-free nitrogen when brazing tostop oxidisation inside the pipework

₀ Also use OFN when pressure testing the system toappropriate pressures

₀ Always ensure you get a proper vacuum to avoidany moisture which reacts with the refrigerant,making it acidic

KEEPING UP TO DATE WITH ERP REGULATIONS

Here, Clive Greenstreet, Category Product Manager at Airflow Developments explains.

The 2015 update to the Energy-related Products Directive (ErP) requires all industrial fans and motors to comply with stringent energy efficiency requirements. This is because the European Union is committed to reducing its CO2 emissions by at least 20 percent by 2020. To achieve this, the Energy-related Products Directive (ErP), was to be introduced in two stages. The first stage in 2009 replaced the 2005 Energy-using Products Directive (EuP) to improve the efficiency of high energy-consuming building services such as heating, hot water and ventilation systems.

The second stage came into force in January 2015. This encompassed an even higher level of legislation regarding the energy efficiency of industrial fans. ErP covers all types of industrial fans (axial, centrifugal, mixed flow) and motors, with an input power of between 125W - 500Kw.

Replace your entire ventilation system?However, those who are responsible for the upgrade of ventilation systems, should not automatically assume that they need to replace their entire ventilation system.

In many instances, upgrading fans to an electronically commutated (EC) centrifugal model is the most cost-effective method of ensuring that a ventilation system is Ecodesign and ErP compliant. In many instances, upgrading fans to an electronically commutated (EC) centrifugal model is the most cost-effective method of ensuring that a

ventilation system is Ecodesign and ErP compliant.

The reality is that in virtually all instances, upgrading the fan to an electronically commutated (EC) centrifugal model is the most cost-effective method of ensuring Ecodesign and ErP compliance.

There are a number of innovative ventilation solutions on the market that can not only save the capital outlay of a new system but also help to reduce long-term building operation and maintenance costs. For example, as well as consuming up to 80% less energy than conventional AC motors units, the new EC fans offer significant noise reduction, variable speed control and remote monitoring options.

Fan choiceFor example, Airflow Developments introduced a range of EC fans and enhanced its AC fan options, resulting in a full range of compliant fans. It is

important to select a product that is

fit for purpose and there are a number

of options to be aware of.

Single inlet EC direct drive

centrifugal fans offer noteworthy benefits in performance and pressure development for applications where space availability for an air-moving device within equipment is limited. This type of fan is ideal for compact cooling in electronics cabinets, lighting, and smaller air conveying systems.

Double inlet EC fans are designed for low noise and high efficiency applications such as general ventilation, industrial warm air movement, VAV boxes, air handling units, telecommunications and transmitter cabins. This range offers high airflows specifically suited for this type of application.

European commitments to reduce energy usage by 2020 have set demanding limits

through the ERP directives for energy consumption and noise. If an air movement system is perceived as being noisy it will be inefficient.

Whilst the amount of primary energy converted to noise in an air movement system is very small, the cause of the noise will have the greatest impact on the energy consumed. Combining high efficiency drive motors with aerodynamically efficient design requires intelligent thinking coupled with numerical modelling techniques. ebm-papst has used these tools to analyse the performance of their product range and has developed a number of innovations that optimise the passage of air through the fan.

When air is on the move it does not react well to sharp changes in direction, high velocities caused by restrictions or turbulent eddy currents. In air handling systems laminar flow is a goal that is achieved by minimising the air velocity in the system, using rigid ductwork, swept or curved bends / splitters and guide vanes where possible. Areas where turbulence occurs can reduce the effective area of a duct resulting in increased air velocities. Turbulence consumes energy in its creation and the increased velocity at these points requires greater dynamic pressure causing a greater load on the fan.

These principals can equally be applied to the fan as the air passes into and through the impeller.

Backward Curved Motorised ImpellerIn developing this backward curved fan, flow analysis identified four areas of turbulent flow through the existing impeller design. At the interface between the rotor hub and impeller back plate and the exhaust of the fan, there was a circulation of low pressure air. At the top of the rotor there was an area of low pressure recirculating air and a high velocity seen at the outer diameter of the rotor head.


A I R M O V E M E N T

Each of these points effectively reduced the working area of the impeller blades resulting in an increased velocity and turbulence induced noise. Using numerical modelling techniques, the impeller was developed to eliminate turbulence and promote laminar flow across the full width of the impeller blade. Increasing the working area of the impeller blade resulted in an increase in performance and efficiency and facilitated a reduction in noise levels. This impeller range is designed for low to medium pressure applications in sizes from 133 to 630mm diameter.

Backward Curved Motorised Impeller – Aerofoil blade designFor medium to high pressure ranges, this backward curved fan range already benefits from rotating diffuser technology, allowing air passing through the impeller to equalise in pressure as it reaches the exhaust. Coupled with an optimally selected EC motor and matched variable speed electronics, the system delivers real world efficiency improvements that are realised in practice and lead to low power consumption.

A further improvement in efficiency has been achieved by the addition of an aerofoil blade design which provides a highly stable, low loss performance with a wider peak efficiency operating range. The inclined trailing edge of the blade reduces exhaust flow turbulence as well as reducing the tonal effect of the blade passing frequency.

This development has also allowed the motor to be positioned optimally to maximise the working area of the impeller. The total improvement in efficiency is in the region of five to eight per cent with a reduction in noise level of over 3dB at the same operating point.

Aerofoil blade designs are available insizes from 250mm to 560mmdiameter.

Addition of a DiffuserThe addition of a diffuser to the hybriddesign axial impeller ranges recoversstatic pressure from the exhaust side ofthe impeller blade. The diffuser reducesthe exit velocity whilst straightening theexhaust flow, thus improving the staticefficiency and performance of the fan.The subsequent reduction in

turbulence losses also reduces noiseand provides a quieter, more efficient fansystem. This improved performance canprovide extra airflow capacity in times ofextreme demand. Alternatively, the extra

performance can be used to reduce thespeed of the fan tomatch the operatingpoint, saving on energy and reducing theoverall noise level of the equipment.

Mitsubishi Electric revealed the latest version of its Hybrid VRF air conditioning systemrecently, which provides simultaneous heating and cooling.

V R F20FEBRUARY 2016

MITSUBISHI ELECTRIC LAUNCHESLATESTHYBRIDVRFSYSTEM

Mitsubishi Electric released the first versionof itsHybridVRF (HVRF) (VariableRefrigerantFlow)air conditioningsystem inSeptember2013 in

theofficesofWorkingEnvironmentsLtd, acompanybased inSouthampton.

in 2008. Chiller sales haveremained stable throughout.

In addition, F-Gas regulations havehad an impact on cooling equipmentmanufacturers. They have had to adapttheir systems to use low-GWP (globalwarming potential) refrigerants tomeetthe ever-tightening rules on carbon andgreenhouse gas emissions.

BS EN378Another concern for property ownersis the challenge of keeping in line withrefrigerant leak detection regulations(BS EN378, in fact). This means that anyair conditioning system used in a buildinghas to have leak detection systemsinstalled if they have refrigerant beingpumped around it. That’s an additionalcost which some properties customersdon’t like.

Large AC ApplicationsFor small air conditioning systems,Mitsubishi Electric, for example, is nowusing R32 refrigerant in its AC systems inJapan. However, larger applications needa different approach, namely using eitherchillers or VRF to deliver the heating and

cooling needs in buildings. Thegap in themarket for larger capacity

heating and cooling systems in the UKwhich Hybrid VRF fills.

Therefore, it looks like the timing isright to being out the next version ofits product.

The Innovative StepGiven that Mitsubishi Electric alreadyhas its YLM VRF series, and recentlyintroduced its e-series chillers into theUKmarket which are part of the ‘HybridVRF’ system, what has changed?The innovative step in the hybrid

system is the new ‘Hybrid BranchController (HBC)’. This is the part of theproduct whichmakes the HVRF unique.The HBC is a self-contained unit in

either 8 or 16-port versions with pumps,an all-in-one flow control valve block andplate heat exchangers. The valve blockmaintains the flow rate and choosesbetween providing hot water or coldwater into the two-pipe system.Because the flow control valve is self-

contained too, it makes designing andmaintaining the system very simple.The HVRF uses the same control

systems as existing Mitsubishi ElectricVRF, such as the remote and centralisedcontrols. The range of HBCs is biggernow too, as is the range of indoor units,which makes HVRF a viable option forcustomers to consider.

Mitsubishi Electricreleased the firstversion of its HybridVRF (HVRF) (VariableRefrigerant Flow) airconditioning systemin September 2013 inthe offices of WorkingEnvironments Ltd, a companybased in Southampton.Onemajor benefit of

the system then was that itused no refrigerant within theoffice building, using water instead todistribute heating or cooling within thesystem. Its challenge, however, was thatit had a limited range of indoor units (onlyeight) whichmeant it was too expensiveas viable heating and cooling solution.Two years on, Mitsubishi Electric has

overcome the challenges with its firstgeneration Hybrid VRF systemwith therelease of its second version. The hybridsystem uses the best of its existing VRFand chiller systems to deliver what theUK air conditioningmarket is demanding,namely efficient, simultaneous heatingand cooling for office spaces, hotelsand other non-industrial workspaces.Over 75% of the VRFmarket uses heatrecovery within the system, as opposedto heat pumps.

Air Conditioning Market ConditionsFurthermore, themarket conditionshave changed since bringing out thefirst generation Hybrid VRF. Overall, VRFsales in the UK are back to where theywere before the big, financial meltdown

What about efficiency and comfort?TheHVRF is efficient too. AndHVRFsystemusing oneHBC has an ESEER of6.3.With twoHBCs in a system that risesto over 7, according toMitsubishi Electric.The company has tested its own

systems in their Hatfield office for overa year now. Their engineers switchedthe system between using the regularVRF onemonth and the HVRF the nextmonth, andmonitored the feedback fromstaff (who didn’t knowwhich systemwasin operation).

The feedback was that theyfelt the HVRF atmosphere wasmore comfortable.What are you going to need to learn to

be able to install HVRF?The first andmost obvious skill you

are going to need to work with HVRF isunderstanding the ‘wet side’ aspect offitting copper pipework for the water.TonyWilliams fromCool Solutions has

already installed an HVRF into the officesof consultants, Hoare Lea in Wales. Hisrefrigeration engineers learnt from theirheating engineers about working with‘wet side’ pipework. It was not a toughlearning curve, he said. The wet sidepipework size is different to refrigerant,but they quickly adapted.Engineers are going to need to learn

about the HBC, of course. However,Mitsubishi Electric designed the HVRFto be simple to design, install andcommission. Any existing approvedinstaller familiar with their kit won’tfind HVRF too challenging to learn, selland install.

PUMP DOWN PROCEDURES ONTOSHIBA VRF AIR CONDITIONING SYSTEMSBy Neil Wooldridge, Technical Manager, Toshiba Air Conditioning

The term pump-down is used to refer to a number of different procedures involving the

transfer of refrigerant within an air conditioning system.

It is commonly used to describe a process that involves drawing as much of a system’s refrigerant as possible into an outdoor unit, to enable work to be carried out on the refrigerant circuit external to the outdoor unit (indoor units, FS-Boxes and pipework).

The idea is to use the compressor on the outdoor unit to evacuate refrigerant from the system into the outdoor unit. The percentage of a system’s charge that can be pumped into the outdoor unit will depend on the ambient temperature, pipe separation between indoor and outdoor units and the outdoor unit’s internal volume.

Any refrigerant left in the pipework must then be recovered using a refrigerant recovery machine.

The term pump down can also be used to refer to the transfer of refrigerant from a failed outdoor unit to a working outdoor unit, using the good unit’s compressor.

Modern VRF SystemsOn early VRF systems, transferringrefrigerant between outdoor unitswas relatively straightforward, dueto the comparative simplicity ofthe design.With today’smodernsystems, however, the procedure ismore complex.

In our experience, thisapproach is rarely used

as it has little benefitto the engineer, ashewill still needto remove thefinal residualrefrigerantwith a reclaimmachine.In practice,

engineers cansimply isolatethe affected

outdoor unit atthe service valves

and either recover to

a service bottle or to the pipework.Once thework has been carried out,and the outdoor unit pressure/leaktested and evacuated, refrigerant isthen released back into the unit.An evenmore efficient option is

available to engineers on systemsequippedwith Toshiba’s award-winning RD6 leak detection andmanagement system.This is primarily designed to

monitor an air conditioning systemfor refrigerant leaks and, in theunlikely event of refrigerant loss,automatically pump down the systemto prevent further leakage - until thesource of the leak can be identifiedand repaired.However, RD6 also enables

engineers to activate a full pumpdown at the flick of a switch,overcoming the need for the usualsequence ofmanual steps, therebyspeeding up thewhole process.

In the case of a systemwith a singleoutdoor unit, where the outdoorrefrigerant circuit requires a repair,this is normally achieved by isolatingthe service valves at the outdoor unitand either recovering the refrigerantfrom the outdoor unit to a servicecylinder using a reclaimmachine, orby using the reclaimmachine to pumprefrigerant from the outdoor unit tothe systempipework. The secondoption simply uses the pipework forcontainment rather than a cylinder.From this, it can be seen that

refrigerant pump down and recoveryprocesses are numerousand varied, and involvedifferent techniques.

1 Face up to the R404A challengeThe refrigerant quota phasedown under F-Gas is going to put

considerable pressure on the supply chain. R404A is the most widely used refrigerant in commercial refrigeration and has the highest GWP. Observers in the industry, including independent commentators, say that supplies of R404A are going to be a problem. Everyone agrees that by 2018 there won’t be suffi cient R404A around to service current needs. There will be shortages and the industry needs to start moving away from R404A very quickly.

2 Go for low GWP optionsIn the context of R404A there is a raft of options depending on

how far down the GWP curve customers want to go. R407F (Genetron® Performax LT™) and R407A are two medium GWP alternatives which are currently available, cost eff ective, and in many cases, energy effi cient. There are also newer generation refrigerants with a lower GWP like Solstice® N40 (R-448A) and Opteon® XP40 (R-449A) that off er additional benefi ts in terms of lower discharge temperatures. These low GWP options are already with us and off er customers the chance to make the switch from R404A now.

F-GAS: TEN STEPS TO BEST PRACTICE

3 Understand CO2 equivalentsThe F-Gas Regulations are based upon working to Carbon Dioxide

equivalents and if you don’t understand how this works achieving best practice won’t be possible. The calculation involves measuring the refrigerant in kilograms and then multiplying this by the GWP. Gas-Trak Online™ (GTO™) from A-Gas, a handy app which will calculate CO2 equivalents, is among the online tools which allows you to do these sums simply and effi ciently.

A-Gas Managing Director John Ormerod with his 10 top tips on how to manage the F-Gas Regulations.

FEBRUARY 2016 acrjournal.uk

4 Up your leak detection regimeMost refrigerant supplied to the industry is for servicing

systems and the reason they have to be topped up regularly is because they leak. Driving down leakage rates is a key part of managing refrigerant use under the F-Gas Regulations. It is well worth putting a lot of eff ort into doing so if you want to achieve F-Gas best practice. Gone are the days of using soapy water and waiting for bubbles to form. Advanced leak detection methods are now a popular choice, with many engineers using trace gas methods such as hydrogen or helium mixtures.

5 Use the right tools for the jobThe trend as we move away from high GWP refrigerants

suggests that the further down the line we go with this, the more we will switch to fl ammable and mildly fl ammable refrigerants like R32. Currently, this takes the industry out of its comfort zone. Flammable refrigerants need to be handled with care and the correct fl ame-proof equipment has to be used to allow you to manage the risks associated with these gases.

6 Improve cylinder trackingAll refrigerant suppliers are levying charges on cylinders, especially on

those described as slow moving. This can end up costing end users a fortune if they have lost track of where they have left them. GTO from A-Gas has a cylinder-tracking tool designed to make this job easier. Free to download on smartphones and tablets, it comes complete with a number of valuable features to help users locate their cylinders.

7 Cut down on paperworkThe F-Gas Regulations put the onus on users to record the amount of

refrigerant they put in and take out of a system. Historically this has been completed on paper but now there are tools available that allow the task to be handled online in a quicker and more effi cient way. GTO provides accurate online reports, 24/7. In turn this removes the burden of endless fi ling and the risk of losing paper copies. We live in a digital world and online tools are there to make the job easier – we should use them.

8 Think lifecycle managementRefrigerant recovery has been a legal requirement within the

industry for some time. Any refrigerant that is recovered needs to be kept within the industry and not released into the atmosphere. We can then recycle it, make it available on the market again and in turn relieve any shortages.

9 Produce top quality jointsMost piping used in the industry is copper and high quality brazing

is needed to ensure you have strong, well-penetrated joints. To achieve this you have to have adequate heat input when you are applying the fi ller material. There are a range of products on the market and they vary as to the amount of heat they off er. Oxygen and acetylene when used together provide a fl ame temperature of 3500°C. This is signifi cantly hotter than propane and propylene. If you are on a site where it is slightly windy or slightly cold, or the pipe

sizes are larger, it can be diffi cult to get the heat required. High temperatures are key to achieving top quality brazing, so only use the best products. This will ensure strong, leak-free joints that are less likely to break and cause equipment breakdown.

10 Keep up to date The industry has faced considerable change over

the past 25 years. This will continue to happen as the F-Gas Regulations have a greater impact on our working lives. So it’s never been more important to keep up with what’s happening through the media online and in print. Trade associations, manufacturers, wholesalers and suppliers also have a role to play here. So keep your eyes and ears open – or you may miss something which could have a major impact on what you do and how you do it.

In Part Two of this article, Peter Dinnage Technical Director at Climalife, discusses the other alternative refrigerants that can ease your move away from the high GWP refrigerant R-404A

R E F R I G E R A N T28FEBRUARY 2016 acrjournal.uk

TIME TO PLAN YOUR MOVE AWAY FROM IT IN

Last month we highlighted the increasing need to move away from R-404A this year and looked at R-407F as an alternative to R-404A. If you missed the article it can still

be found on the ACR Journal website. This month we cover lower GWP alternatives.

Climalife.indd 28 27/01/2016 10:46:50


R E F R I G E R A N T


Lower GWP alternatives to R404AThere are a number of alternatives approved by compressor manufacturers with a GWP signifi cantly lower than R-404A and whilst each have slightly diff erent properties, it is their GWP where there is most diff erence. Both R-448A and R-449A have GWPs (AR4) just below 1400. Both contain R-125, R-134a, R-32 and R-1234yf, but R-448A also contains R-1234ze and it’s the presence of the HFOs which take the GWP lower than that of R-407A (2107) and R-407F (1825). Both these lower GWP alternatives can be used in supermarkets, cold stores and direct expansion food processing applications that have previously used R404A.

Energy saving benefi ts compared to R-404A exist but may vary according to application and operating conditions. These savings tend to be greater in medium temperatures applications.

Pressure temperature tables are available in various forms and feature on many of the popular free slide rule apps that are now available for smartphones.

R-449A (Opteon™ XP40) is already proving a suitable alternative to R-404A with use growing across Europe in a wide range of applications. In the UK it has already been used in new convenience store applications and has been trialled in a number of larger supermarkets for retrofi t and roll out in 2016 in further stores. On the industrial side it has been used successfully for retrofi t and

has proven to be an easy conversion to carry out from R-404A, with no need to change from the POE oil used with R-404A. Where electronic expansion valves are in use, they can be adapted to R-449A whilst a small adjustment of thermostatic valves and the superheat settings are usually required for optimum operating conditions.

To meet the phasedown requirements of F-Gas in 2018, retrofi tting of existing R-404A equipment to lower GWP refrigerants is going to be vital to ensure the reduced quota meets the demands of the market. The lower GWP refrigerants such as R-449A (Opteon™ XP40) and R-448A will have a major part to play.

New Store on Opteon™ XP40 (R449A)Whilst selection of new equipment

will depend on the equipment manufacturers, for retrofi tting existing systems the choice is with the contractor or the end user. Nevertheless the selection software of the compressor manufacturers for R-404A alternatives can still be used as a guide along with case study information from those where

R-449A IS ALREADY PROVING A SUITABLE ALTERNATIVE TO R-404A WITH USE GROWING ACROSS EUROPE IN A WIDE

RANGE OF APPLICATIONS.

TIME TO PLAN YOUR MOVE AWAY FROM IT IN

conversions have taken place.It is always worth remembering that

if you are retrofi tting to follow the conversion guidelines from the producer / supplier as this will help ensure the check list is followed and potential pitfalls are avoided.

A2L Refrigerants as R404A replacementsMany have been holding off replacing R404A in the hope that even lower GWP replacements will be available and possibly a better option. However, A2L rated refrigerants will not be a retrofi t option due to their mild fl ammability and even for new equipment there will be charge size restrictions based on the size of the room which will limit their use to small equipment. Some of these A2L refrigerants with low GWP will be a good option for new systems with a small charge, however the selection and approval process will be led by the equipment manufacturers and that may take time and assumes EN378 will formally incorporate the recommendations now on the table.

The need to replace R404AIf you are still in any doubt of the need for action to replace R404A in 2016 we recommend you look at the EPEE Gapometer presentation which can be found here; http://www.epeeglobal.org/epeedocs/internet/docs/2015-10-26-GAPOMETER-Final_9102.pdf

Do also speak to refrigerant specialists, such as Climalife, to review all the options available to you and ensure it is the right choice for your particular system.

Cooling has beenmuch ignoredin the energy debate sofar, but is a pillar ofmodern

civilization.We need cold chains ofrefrigerated storage and vehicles topreserve food from farm to fork andprotect vaccines.Weneed to cool the data centres

thatenable theonlineeconomy.Weneedair conditioning tomakebuildingscomfortableplaces to liveandworkwherever theyare.But there is aneconomicandenvironmental price topay for cooling–or the lackof it.Developing countries, where cooling

infrastructure is rudimentary or non-existent, suffer high levels of post-harvest food loss, causing knock-onwastage of water and land and continuedhunger, ill-health and poverty. The lack ofadequate cold storage and refrigeratedtransport causes twomillion vaccine-preventable deaths each year, and theloss of 200million tonnes of food. Asthe global population heads towards 10billion by 2050, there is no question thatsuch countries will need farmore cooling.

Rising AspirationsIn the rapidly industrialisingcountriessuchasChinaand India, coolingdemand is

Booming demand for cooling, particularly in the developing world, posesserious challenges around energy and the environment. But it also presentsa massive opportunity.

estimate that if nothing is done, withinfifteen years the electricity needed topower all cooling services worldwidewillrequire an additional 139GWgeneratingcapacity – ormore than Canada. Thiswould cause an additional 1.5 billiontonnes of CO2 emissions per year – threetimes Britain.And that’s just from the power stations

themselves. Cooling is also responsiblefor leaks of F-gas refrigerants, which arethemselves highly potent greenhousegases. Our analysis shows that whileF-gas leakage accounts for just 17%oflifecycle CO2e emissions of transportrefrigeration units (TRUs) in the EU,diesel consumption accounts formost ofthe rest, and for high levels of NOx andparticulate emissions. A diesel TRU can

emit up to 6 times asmuchNOx and 29times asmuch PM as amodern (Euro VI)truck propulsion engine. These are twoof the key pollutants that contribute to3.7million premature deaths throughoutdoor air pollutionworldwide eachyear. The current global TRU fleet of fourmillion could grow to almost 18millionby 2025 to cater for pent up demand indeveloping countries.Soaring cooling demand in developing

countries only adds to high existingdemand in the developed. In Britain,for example, around 16%of our powergoes on cooling, and across the EU it isestimated that cooling for buildings couldrise by over 70%by 2025.

cooling projects in complex and criticalapplications such as hospitals, datacentres,manufacturing industry and largecommercial offices.“Traditionally, rental chillers operate

After the deadline, companies that have failed to notify the EA will see enforcement action

begin. To encourage businesses, the EA recently sent out informal warnings to organisations that have not advised them they were ESOS compliant.

That meant around one third of all businesses eligible for the mandatory scheme received the warning.

About 4,000 businesses submitted their final ESOS report by the original deadline of 5 December deadline. A further 2,500 had notified the Environment Agency of their intent to comply.

Although the legal deadline for compliance remains 5th December 2015, companies will not face enforcement action if they notify the EA of compliance before 29 January 2016. The Agency is also offering a three month derogation, after enforcement notices are sent out, before any civil action will occur.

ESOS AuditESOS energy audits of buildings have a specific route that is allowable. The appointed lead assessor (Registered on the Approved Professional Body ESOS Register) has the responsibility to assess any existing energy audits. This covers the organisation’s portfolio of buildings that contribute to the “Significant” energy use. These audits have to relate to the reference period and they have to be ESOS Compliant Energy Audits.

For many users of refrigeration equipment, the energy consumed by


E N E R G Y E F F I C I E N C Y

their refrigeration plant is often one of their largest consumers. This can account for anywhere between 25% and 60% for food production facilities.

For cold storage, it can be towards to 85%. To identify the true opportunities for energy savings, companies should use specialist independent experts, in both refrigeration and energy efficiency, to carry out the energy audits.

TM44 Air ConditioningInspections and ESOSSince 4th January 2011, all organisations in England and Wales with air-conditioning systems over 12kW, have to carry out an independent energy inspection of their units. (See Article 9 of the Energy

Consultants BJA are reminding businesses that they have to be Energy Savings Opportunity Scheme (ESOS) compliant by 29th January 2016. ESOS means that companies have to audit their energy usage.

Around 3,000 UK businesses have not told the Environment Agency (EA) that they intend to follow the ESOS legislation. If an organisation meets the qualification criteria but fails to follow the legislation, it could face a fine of up to £90,000.

BEYOND COMPLIANCE

BJA.indd 40 27/01/2016 08:36


E N E R G Y E F F I C I E N C Y

WHAT IS ESOS?The ESOS Regulations 2014 bring into force Article 8 of the EU Energy Efficiency Directive and mandate that all large businesses in the UK undertake comprehensive assessments of energy use and energy efficiency opportunities at least once every four years.

The deadline for the first compliance period is 29th January 2016, by which time qualifying businesses will have to achieve compliance with the regulations and notify the Environment Agency.

The criteria for inclusion to ESOS is not straightforward, but it applies to any ‘large undertaking’ that carries out a trade or a business, and any corporate group where at least one member of the UK group meets the ESOS criteria.

A large undertaking is one that employs at least 250 people or has an annual turnover over £40 million and a balance sheet more than £34 million. Most public sector bodies are excluded, but some, such as many Universities may qualify.

Performance of Buildings (Certificates and Inspections) Regulations 2007).

TM44 Air Conditioning Inspections and certification are still a mandatory. But, they will not on their own meet the ESOS rule as they only cover comfort cooling air conditioning and exclude other areas of the organisation’s energy usage, such as process cooling.Therefore, TM44 does not in itself make an organisation ESOS compliant. Yet, the report produced by a TM44 audit could and should influence the Energy Saving Opportunities database. Energy savings already identified in the TM44 report would be incorporated if the Lead assessor approves their inclusion in to the ESOS report.

So TM44 Air Conditioning inspections remain important to meet legal obligations and also help with ESOS.

BJA is working with leading retail, commercial and industrial organisations to meet their legal obligations and identify inefficient units to reduce energy consumption.

Beyond complianceOnly complying with the Regulations misses the point of ESOS. Use ESOS to identify opportunities to reduce energy use and to cut consumption, emissions and cost.

Whilst there is no statutory need to take action on these opportunities, not to do so is to reduce ESOS to a costly compliance exercise rather than a means to achieve real savings.

Opportunity?There will be some that approach ESOS as a ‘box ticking exercise’. For them this will not be an opportunity gained, but an opportunity lost. There are real proven business benefits for organisations in reducing the amount they spend on energy.

Refrigeration and air conditioning plant users often waste around 20% of their annual energy costs by using inefficient equipment.

An ESOS audit will identify this equipment. BJA’s expert knowledge and tailored services make the implementation of energy reduction projects easy and cost effective.

Looking beyond the low-hanging fruitIt’s no surprise that low-cost/no-cost energy efficiency measures tend to get the most uptake. But, it is a misconception that only the low-hanging fruit is worth harvesting. On the contrary, it’s estimated that so-called ‘investment’ measures (those involving slightly longer payback periods) can unlock typical energy savings of 15%. That is 15% on top of that saved by low-hanging fruit upgrades.

The landscape of energy-saving technologies is evolving so rapidly that many solutions that were once thought of as longer-term investments are now becoming low-hanging fruit. Prices are coming down, payback periods are improving – all of which makes it worthwhile to look beyond the obvious and to make sensible, well informed decisions when it comes to investment projects.

Making well-informed investmentsThe time and money currently invested to achieve ESOS compliance is unvoidable unless one wishes to risk facing a fine. Implementing and maximising the energy savings opportunities identified, and to take full advantage of the ESOS opportunity is the most effective way to ‘offset’ the cost of the ESOS audit.

This will involve making upgrades, installing new equipment, improving procurement, etc,. BJA has specialist project managers in the cooling and energy efficiency sector, and can manage this process for the end-user.

BJA advises companies not to look at ESOS as a pointless box-ticking exercise. Instead, BJA encourage them use it as a chance to improve their energy strategy, to reduce energy waste, and to uncover the next layer of energy savings.

BJA Refrigeration Consulting Engineers are specialist independent refrigeration consultants who work with many of the UK’s leading food processing, storage, retail and distribution companies to ensure that their clients enjoy the most energy efficient, reliable, and innovative solutions. They provide specialist ESOS energy audits, and also undertake TM44 Air Conditioning inspections. With a long background in project management, they are well placed to advise of energy saving investments for cooling equipment and to manage the implementation process from start to finish.

There is a right way and a quick way; sometimes they are the same thing, but more often we

think the right way will delay us from getting to the next three jobs.

Consider then that the failure to do something correctly, that might only involve 5 minutes more work, could result in weeks off work with an injury or a lifetime dead (that’s a more permanent delay, is it not?). That perceived need to save time is often why accidents happen, coupled with the certainty that all men have “that it will not happen to me”!

Engineers often don’t safely isolate electrical equipment before working. I worked for decades without correctly locking off electrical equipment before undertaking maintenance or repair work. The Health & Safety culture in the refrigeration industry has certainly improved beyond all recognition from those days, but largely from a paper trail perspective. Engineers still follow less than best practice on a daily basis.

So, what are the reasons / barriers to safe electrical isolation, with the inevitable first on my list:

Often we hear “I have always done it like this”. If we are honest with ourselves we have all said it at some time, the more fundamental question we should ask is “have we always been doing it right?”.

TO ISOLATE OR NOT TO ISOLATE - WORKING DEAD TO STAY ALIVEby Stephen Benton, Cool Concerns

So with the majority of us fitting now uneasily into categories 1 and 5 of the above read on.

Incorrect isolation can result in electric shock and / or injuries due to equipment starting up unexpectedly. Both outcomes are potentially fatal at worst and can inflict horrendous or life changing injuries at best. Remember, when you joke with colleagues that you

got yet another electric shock “only a little tickle”, this is only emphasising to everyone that there are some basics missing in your competence.

Engineers are not always aware of correct isolation procedures and may not have the appropriate training or equipment. We have developed simple training to meet the needs of one contractor whose engineers had suffered a few accidents which

1. I have always done it like this;2. I don’t have an safe electrical isolation procedure;3. I don’t have electrical isolation ‘lock o� ’ equipment;4. I thought I was doing the customer a favour;5. I have items 2 and 3 but still make the decision based on 1, 4 and 6;6. It’s never happened to me!

TO ISOLATE OR NOT TO ISOLATE - WORKING DEAD TO STAY ALIVE

₀ What to expect when you measure voltage, current, resistance;

₀ How to measure, using appropriate tools safely;

₀ Working dead (an odd title but directly related to staying alive);

₀ Safe electrical isolation;₀ Diagnosing electrical faults – probes, fan motors;₀ Replacing probes and motors so the

replacement works reliably – cable joints.

Equipment Required:

₀ Isolation padlock & key₀ Multiple worker isolation padlock tag₀ Isolation devices to suit di� erent isolators / MCB’s etc₀ Warning notices₀ Voltage tester₀ Voltage proving unit.

Safe Isolation

1. Identify the circuit or equipment to be worked on2. Check condition of voltage tester and operation against a known

voltage supply3. Isolate supply and secure isolation – lock o� (multi lock o� if multiple workers)4. Prove circuit dead – use voltage tester and re check against a known

voltage supply5. Retain keys and post ‘caution’ and ‘danger’ notices6. Take precautions against adjacent live circuits / equipment – if any7. Issue permit to work8. Work dead.

Reinstating the Supply

1. Ensure all work is complete2. Ensure all covers and lids are replaced3. Remove lock o� and warning notices (multi unlock if multiple workers)4. Reinstate supply5. Turn on equipment locally if possible6. Sign o� permit to work.

could have been avoided with safe electrical isolation practices. In reality most refrigeration engineers need an introduction to / a reminder of good practice. This is part of a larger culture change needed throughout our industry to ensure that we are all safe in an increasingly pressurised work environment.

What we covered – back to basics:The training includes practical

hands on exercises. Each candidate is assessed using RoSPA accredited e-learning and a practical assessment measuring single and three phase power supplies and safely isolating, confirming isolation, locking off and reinstating.

For practical health and safety to triumph we need a culture change at all levels. The A4 folder of risk assessments we all carry in the vehicle is less important than using the right electrical test and lock off tools and competently isolating and

locking off an electrical supply before working on a piece of equipment.

So ask yourself, do you have the below in your tool bag and do you know how to use and apply it following the procedure? If you do, great! If you don’t then correct that today, yours or a colleague’s life might depend on it!

If it is not safe to work - be confident to say NO.

Colin Usher an architect and director at Liverpool-based John McCall Architects, incorporated Stiebel Eltron’s heat pump technology in his new-build property – a four bedroom house in West Kirby that

he designed himself. Colin demolished the original property on-site and developed a new home, at a total cost of £240,000.

H E A T P U M P S46FEBRUARY 2016 acrjournal.uk

requirements of the UK market. The range is Stiebel Eltron’s most compact yet and off ers optimal effi ciency using a single phase supply. All component parts of the machine have been optimised to suit UK demands and the pump has the best seasonal performance on the market in its class.

The heat pump, supplemented by the use of solar panels, is now providing all heating and hot water energy requirements for Mr Usher’s home.

As a result of the air source heat pump,

Stiebel Eltron UK heat pump technology is helping to keep energy bills to just £15 a year for a North West home-owner and self-build architect.

The new-build property has been designed as an eco-home, with minimal energy usage.

The private house comprises an insulated masonry and concrete structure, under fl oor heating, triple glazing, LED lighting, heat recovery ventilation and an air source heat pump.

Stiebel Eltron’s WPL15 air source heat pump is an integral part of the property’s energy effi cient operation. The WPL15 AS product was developed by Stiebel Eltron UK to meet the bespoke

savings of £1800 per year are being made against traditional fuel sources- contributing to Mr Usher’s exceedingly low energy bills. The house has now been occupied for two years and the energy cost for heating, lighting, hot water and cooking was less than £15 per year for this period.

The £15 yearly energy costs are so low, in fact, that the property has received national media attention, featuring in the Daily Mail and on BBC broadcast and online channels. In addition, the project was recently hailed as the winner in the Domestic New Build category of the Buildings and Energy Effi ciency Awards 2015.

Commenting on the energy savings reaped by installation of the Stiebel Eltron heat pump, Mr Usher said, “We are delighted with our new home and to have won the Domestic New Build category of the Buildings and Energy Effi ciency Awards 2015 because it proves eco homes don’t have to be over expensive or need to be conspicuously unconventional in appearance. The property is very comfortable to live in and its appearance is not incongruous with surrounding houses. This is helped by Stiebel Eltron’s air source heat pump – which is unobtrusive and makes barely any operation noise. Our home dispels the myth that an eco-driven home needs to be expensive and radically diff erent in appearance.”

Measures and manages water flow on demand. The incoming flow rate is closely monitored, regulating the pump speed as required. This clever technology collects data, adjusts flow rates and switching levels.

Manages voltages and electric current at source, enabling the pump to be used universally making installations easier. Also, allows the pump to be controlled on demand which ultimately leads to a longer pump life span.

Using a visual LED heartbeat, Pulse gives an instant view of what the pump is thinking and doing. Allows quick diagnosis without having to ‘un install’ or ‘break into’ the pump potentially saving time and money.

i4 pumps have truly quiet running due to having soft start as standard. The pump will regulate its speed relative to the influx of water, only removing the water it needs to – leading to much quieter running.
