1. PRODUCT PRESENTATION

NECS, the new CLIMAVENETA R410A proposal

Scroll compressors, featuring high effi ciency, low vibrations

and low noise emissions.

Flexible range. Available from 113 – 341 kW with 9 sizes and

5 versions.

Part load effi ciency with EER > 4.3

New controller with QuickMind.

Idrorelax, for turning your ideas into reality.

Climaveneta introduces its new NECS-W range of chillers and

heat pumps with scroll compressors, plate exchangers and R-

410A, with both one-circuit two compressors and two-circuit

four compressors, focused on maximum effi ciency and mini-

mum noise emission.

Why R-410AAlthough R-410A is a blend, it behaves just like a pure gas and features a negligible temperature glide. Thanks to its outstand-ing heat conductivity, R-410A contributes towards achieving high system effi ciency. R-410A is also an ecological gas be-cause its high effi ciency reduces electricity consumption and consequently CO2 emissions and because it does not damage the ozone layer (ODP = 0).

The scroll compressor has been expressly redesigned for use with the new gas and is now even more compact and silent

than before.

Complete versatilityNECS-W units are designed to fully satisfy any application or installation needs throughout a complete range of models, hy-dronic confi gurations and accessories. NECS-W is available in chiller mode (chilled water production), heat pump for hot wa-ter production (plus possible water side reversal) NECS-WH and fi nally heat pump with “refrigerant side reversal” NECS-

WN (chilled/hot water production).

High effi ciency at partial loadClimaveneta has designed NECS-W units with the goal of guaranteeing high effi ciency at part load. The result achieved in the new single-circuit dual-compressor is an ESEER up to 6.01, equivalent to a 33% saving in seasonal energy consump-tion compared to traditional R-407C double-circuit unit.

Advantages

The technological choices aimed to provide the maximum

overall quality and the use of the most innovative technologies

make NECS-W a unit able to ensure maximum energy effi -

ciency, easy installation thanks to its compact size, versatility

and settings for integration in the Idrorelax centralised hydronic

system (www.idrorelax.it).

Reversible heat pumpsAll NECS-W are available as NECS-WN heat pump model; this model completes the Climaveneta water cooled units range.Making a comparison between NECS-WN and a traditional “water side reversal” heat pump, reductions in installation spaces and an easier water connection layout are achieved. It

means saving in installation costs and time.

Condensing pressure control deviceNECS-W electronic control can manage the best suitable con-densing pressure control device for every applications: pres-sostatic valve, 2 or 3 way modulating valve and inverter on the condenser pumps. NECS-W units can therefore be combined with dry-coolers, evaporating towers and geothermal probes, or used to cool

open-loop water (e.g.: aqueducts, wells, water tables).

Kit pumps available on hot/cold sideNECS-W units are designed in order to minimize installation time. Units are available with both evaporator /condenser hy-dronic kit.Hydronic kits are fully accessorised with every hydronic device in order to obtain: space reduction, installation costs saving and shortening installation time.The units are plug&play thanks to the feasibility to install 1 or 2 pumps on board, high and low pressure head on both evapora-tor and condenser sides.

IV NECS-W_0604_1204

NECS-W

HFC R410A

Consistent with corporate culture, the NECS-W series was

designed to offer extremely high quality products with cutting-

edge technology focusing on maximum energy effi ciency at

both full (EER) and part load (ESEER).

Energy effi ciency at full loadNECS-W units stand out for their particularly high EER energy effi ciency index. This result was achieved by focusing on the

design of plate exchangers both on the condenser side and on the evaporator side.These construction choices have both increased effi ciency and provided extremely high levels of reliability while signifi cantly increasing compressor working life.

Energy effi ciency at part loadAttention to energy consumption is continually gaining impor-tance, even at European level.The installed chiller unit works at full load only for extremely short periods of time while most of the energy is produced with part loads between 50 and 75%.

The ESEER parameter proposed by Eurovent, takes part load operating conditions into account when assessing unit effi -

ciency.

1.1 Energy indices ESEER and IPLV

Increasingly closer attention is being paid towards the power

consumption of air-conditioning equipment, both in Europe and

elsewhere.

For many years in the United States, reference has not just

been made to effi ciency at rated conditions. A valuation index

is used which considers marginal operation of the unit at rated

conditions as well as the increased usage when the separation

stages of the cooling compressors are used.

The valuation index adopted in the United States is called IPLV

(Integrated Part Load Value) and is defi ned in the regulations

issued by ARI (American Refrigeration Institute).

ARI Standard

IPLVARI =(1*EER100%

Where EER100%

, EER75%

, EER50%

, EER25%

are the effi ciencies of

the chiller in the various load conditions (100% - 75% - 50% and

25% respectively), calculated in the external air temperature

conditions shown below. The temperature of the water leaving

the evaporator is considered constant at 6.7°C in all load condi-

tions, with a delta of 5°C in the full load condition.

The multipliers 1, 42, 45 e 12 are the cooling performance coef-

fi cients in various load conditions statistically calculated by ARI

on the basis of surveys conducted, for various types of build-

ings and operating conditions, in 29 American cities.

ESEER Comparison:

NECS-W single-circuit vs. traditional dual-circuit unit.

The comparison proves that the new single-circuit NECS-W

units with R-410A feature signifi cantly greater energy effi ciency

(ESEER + 38%) over traditional dual-circuit units with R-407C.

Using the energy indices

After establishing which index to use and estimating the total

power required by the system in the summer mode (in kWh),

we can calculate seasonal electricity consumption (in kWh) us-

ing the following formula:

Power absorbed = Power requested / Index of effi ciency

The real power calculation can be obtained more correctly in a

“dynamic” form, that is, considering the load performance curve

at different external temperatures, the location and the refer-

ence number of operating hours.

These fi gures will allow plant consultants and designers to

make their evaluations depending on the type of building, the

place of installation and the type of heat load. etc.. They can

also determine the energy index using the method that best re-

fl ects plant requirements and can make comparisons between

similar or equivalent systems using the same reference unit.

All the two-compressor units are equipped, as a standard, with

the “W3000 Base” keyboard with LED display.

On the four-compressor units the user friendly “W3000 Com-

pact” keyboard with LCD is installed as a standard; also avail-

able, on demand, for the two compressors units.

The “W3000 Compact” on board keyboard can be connected to

a remote keyboard with LCD display.

Main functions: QuickMind, local and remote FWS supervi-

sion, dual setpoint management, etc., confi rm Climaveneta’s

commitment to continually developing its electronics technol-

ogy. The heat pumps, moreover, are fi tted with the original

Climaveneta defrosting control system called “Smart Defrost”

which considerably reduces defrosting times, thus improving

the energy performance of the unit. Interfaces with BMS sys-

tems: METASYS®, MODBUS®, LONWORKS®, SIEMENS®,

TREND®.

Black Box logs data relative to 200 alarm events which can be

printed with a personal computer.

CONTROL UNIT with LED display

QuickMind is a special control unit which monitors the main op-

erating parameters, predicts system behaviour and anticipates

unit settings in order to constantly optimise performance; it al-

lows both return and delivery water temperatures to be chosen

as adjustment parameters. It can reduce outlet temperature

fl uctuations even with a small amount of water in the system.

When, for dual-compressor chillers featuring a maximum of 12

start-ups per hour and using a traditional adjustment system,

the minimum recommended water content is 5.5 l/kW, Quick-

Mind ensures the same chiller operates correctly even with a

water content of just 2.5 l/kW and considerably reduces outlet

temperature fl uctuations. The above graph shows that outlet

temperature fl uctuations with QuickMind are limited to 4.3°C

as opposed to 7.54°C if the traditional adjustment system were

used, without even ensuring an acceptable minimum compres-

sor start time.

NECS-W

HFC R410A

The new NECS-W units can be equipped with evaporator and/

or condenser hydronic kits. The kit incorporates the main hy-

draulic components thus optimizing hydraulic and electrical in-

stallation space, time and costs.

Moreover NECS-W can be provided with INVERTER pumps on

the condenser side. This device enables the condensing pres-

sure control, through the variable speed pump, reducing pump

energy consumption.

Available confi gurations

Evaporator and/or condenser hydronic kit can be provided with

following confi gurations:

Hydronic group 1 pump low head

Hydronic group 2 pumps low head

Hydronic group 1 pump high head

Hydronic group 2 pumps high head

Units can be equipped with up to 4 pumps, two on the evapora-

tor and two on the condenser side.

2-pole pump

Low head pump with 100 kPa external static pressure.

High head pump with 200 kPa external static pressure.

Horizontal one-piece centrifuge pump with one impeller, axial

suction and radial delivery, AISI 304L stainless steel pump body

impeller. The section of shaft in contact with the liquid is made

from stainless steel. Mechanical seal made from components

in ceramics/carbon/NBR/AISI304. Three-phase electric motor

protected to IP55, insulation class F, suitable for continuous

service.

Second pump

A second stand-by pump for high or low pressures is available

on request. The pumps are automatically exchanged on the

basis of a rotation programme and the stand-by pump cuts in

automatically if the primary pump fails. The two-pump hydron-

ic assembly is also fi tted with check valves to ensure the unit

works correctly.

Water-side mechanical fi lter (optional)

Y-fi lter designed and built to capture the impurities in the hy-

draulic circuit. It is fi tted with a 0.9 mm stainless steel mesh car-

tridge which can be replaced without removing the valve body

from the piping.
