The highest energy recovery available.

The Company

Building on over 20 years of European

innovation Tempeff North America is

pleased to offer Dual Core energy recovery

ventilation equipment with the highest

efficiency available. In these times of

escalating energy costs, and concern over

environmental impact, Tempeff Dual Core

Technology is an ideal solution for your

building ventilation needs.

Ventilation

Any building owner or operator knows

that due to the extreme North American

climate, conditioning ventilation air is

very expensive. However, that ventilation

air is extremely important to ensure good

building health, and in turn health of

occupants, leading to increased comfort

and productivity. Thanks to Tempeff Dual

Core’s high efficiencies, owners can meet

or exceed minimum legislated ventilation

requirements, without the usual high

operating costs of traditional ventilation

heating and cooling equipment.

Dual Core Energy RecoveryTemperature Efficiency

Tempeff North America products employ Dual Core regenerative technology

that offers up to 95% temperature efficiency. Other available technologies offer a

maximum of approximately 50% to 75% efficiency under ideal circumstances, and

much lower real effectiveness in colder temperatures due to frost. The Dual Core design is

significantly more energy efficient in all conditions, thus payback periods are extremely attractive.

Latent Recovery

In winter modes condensation will form on the exhausting heat exchanger. When the cycle changes the outdoor

air is passed over the heat exchanger, and that moisture is added back to the airstream. This reduces the need for

adding humidity to the conditioned space. In many cases up to 70% latent recovery can be obtained.

Frost Resistant Most heat recovery technologies suffer from the same basic drawback. In cold temperatures frost will form on the

exhaust side of the heat exchanger, dramatically reducing the heat recovery effectiveness. If a defrost cycle is not

employed, frost will build up until the entire heat recovery device becomes inoperable. During the defrost cycle the

heat recovery device is usually bypassed, or put into a mode where effectiveness is significantly reduced so that

the frost can melt. Thus in times where heat recovery is needed the most (ambient temperatures are coldest) the

effectiveness of the device is the lowest. As a result, most technologies require additional heat capacity for these

times, usually sized as if there is no heat recovery device at all to ensure the building does not experience periods

where cold air is being introduced (during defrost cycles). In turn real effectiveness is greatly reduced, increasing

operating costs, equipment costs, and life cycle costs.

With the Dual Core design frost will never build up in a typical application. With the cycling heat exchanger, frost

doesn’t have a chance to form, and one heat exchanger is always delivering conditioned air to the space. In many

cases additional heat is not necessary for the ventilation air, due to the real effectiveness of the system! As a result

operating costs, equipment cost, installation cost and overall life cycle costs are significantly reduced compared to

traditional heat recovery technology.

Low Maintenance

With few moving parts, maintenance of the system is very low. Due to cycling nature of the heat exchangers dust

rarely builds up on the heat exchangers, thus frequent cleaning is not required. If cleaning is required, cores are

easily removable for cleaning as necessary.

Long Term performance

In a third party audit of a 17 year old installation, performed by CIT Energy Management AB, it was found that

the efficiency of the equipment was the same as the day it was installed (90% measured temperature efficiency).

The product has also been rigorously tested in one of the coldest climates in North America, Winnipeg, Manitoba,

where temperatures reach below -40 0F (-40 0C). Thus owners of Tempeff equipment can rest assured that they

will enjoy the high performance of their system for a long time.

Typical Applications

Dual Core units can be applied wherever

ventilation air is required. Dual Core units meet

or exceed ASHrAE 62 – 2004 acceptable cross

leakage rates, and are an excellent solution for

energy recovery in ventilation applications.

Some common applications:

• Schools

• Apartment/condocomplexes

• Factories

• Parkades

• Swimmingpools

• Paintshops

And so many more….

Design Considerations

Due to the Dual Core’s innovative damper design, outside air dampers are not necessary to isolate the atmosphere

from the building when the unit is off.

Due to the Dual Core’s fast acting damper design, cross leakage rates are less than 1-3% which is well under

ASHrAE 62 -2004 prescribed acceptable cross leakage rates for energy recovery applications. Consult your local

approval agency to ensure they will allow ASHrAE’s recommendation.

When choosing a location for the unit, ensure that the duct length for outside/exhaust air is as short as possible.

When the cycles switch, the exhaust air in the duct will be drawn back into the outside air. Cross leakage is less

than 1-3%, but will increase with longer outside air duct runs.

If the unit is located indoors, ensure ducting for outside/exhaust air is designed to handle the switching positive

and negative pressures. These ducts will experience alternating positive and negative pressures every 60 seconds.

The supply air and exhaust air duct work (to the unit) must be well insulated to assure maximum heat recovery is

attained. Insulating outside air ducts located in non-heated areas is not necessary.

After 60 seconds, the dampers reposition. Now Energy Core B is adding the energy it reclaimed in Phase 1 to the supply air stream, heating it up. Simultaneously Energy Core A is “recharging” by absorbing energy from the exhaust air stream. Phase 1 and Phase 2 will alternate every 60 seconds, constantly delivering extremely high energy recovery regardless of outdoor air temperatures. Because the cores switch cycles every 60 seconds, frost does not have a chance to build up, thus energy recovery is constant day in and day out, unlike other traditional types of energy recovery devices.

How to select a Tempeff Dual Core unit Before starting, establish the required airflow for the

space this unit will be applied to. The selection guide and

performance charts in this manual assume a balanced

airflow system, where supply and exhaust air volumes are

equal. If an unbalanced system is desired, contact your local

Tempeff representative for design assistance.

Step 1

Consult the performance chart on page 7 & 8 and select a

model that is suitable for the air volume desired. Dual Core

models are sized based on required airflow. The models

listed are in cost effective order, the first unit is the lowest

cost, but will typically have a lower temperature efficiency.

The other model options listed will progressively grow in

initial cost, but will have a higher temperature efficiency.

If the air volume needed is larger than the chart reflects,

contact your local Tempeff representative for design

assistance. larger air volumes than catalogued are available.

Step 2

Calculate the leaving air temperature. First determine the

outdoor (entering) air temperature and the exhaust air

temperature. For winter mode calculation the temperature

efficiency of the unit can be obtained from the performance

chart on page 7 & 8. For summer mode the temperature

efficiency can also be obtained from the performance chart

on page 7 & 8.

Temperature Efficiency is calculated by:

Et = ________________T2 - T3

T1 - T3

Et = Temperature efficiency

T1 = Temperature of Exhaust air (Dry Bulb)

T2 = Temperature of Supply air (Dry Bulb)

T3 = Temperature of Outdoor air (Dry Bulb)

Isolating for T2 (supply air) we find:

T2 = Et(T1-T3) + T3

This formula can be used for both winter and summer

modes.

Using the calculated supply air temperature, we can now

determine whether supplementary heat or cooling is required

to meet space conditions.

Determine:

1. Desired Tempeff Dual Core model

2. Supply air temperature in both Summer and Winter modes

3. Regained sensible heating and cooling in BTUH

4. HP requirements for supply and exhaust fans

1. Consulting the performance charts on page 7 & 8 the

following 3 options are available at 10,000 CFM.

1. RG 16000

2. RG 20000

3. RG 25000

The rG 20000 has a temperature efficiency of 89.6%, thus is

very close to the target efficiency. The summer efficiency for

the rG 20000 is 79.6%.

2. Supply air temperature is determined by:

T2 = Et(T1-T3) + T3

Where:

Et = Temperature efficiency

T1 = Temperature of Exhaust air (Dry Bulb)

T2 = Temperature of Supply air (Dry Bulb)

T3 = Temperature of Outdoor air (Dry Bulb)

Winter:

T2 = 0.896 (70 – (-4)) + (-4)

T2 = 62.3 deg F

Summer:

T2 = 0.796 (75-85) + 85

T2 = 77.0 deg F

Using these numbers we can now determine whether

additional heating or cooling is required. Since the desired

winter supply temp is 72 deg F, a heating device is required

to raise the supply temperature by 9.7 deg F. Cooling supply

temperatures match desired, thus no additional cooling is

required. Selecting a heating coil to accomplish the

9.7 deg F adds 0.1” W.C to the system.

Step 3

Calculate regained sensible heating and cooling. Now

that the supply air temperature has been calculated, it

can be used to determine how much sensible heating

and cooling has been regained.

The formula to accomplish this is:

BTUH = (T2-T3) x Airflow x 1.08

This can be used for both winter and summer, if

the number is a negative, that is the sensible BTUH

cooling regained by the unit.

Step 4

Calculate the HP required for both supply and

exhaust. If the supply and exhaust fans are existing

or supplied by others, the static pressure drop added

to the system can be obtained from the performance

chart (Core Pressure Drop). This pressure drop will be

added to both supply and exhaust air streams, thus

the motors must be sized to account for this added

pressure.

If the fans are to be included in the Tempeff unit,

simply add the external static pressure (ESP), any

additional heating or cooling coil pressure drops, and

special filter pressure drops, to get your total ESP.

Using the performance chart, find the column that

corresponds to your total ESP, and select the BHP that

matches the model selected. This value will be used

for both supply and exhaust HP requirements.

ExaMpLE: A space requires 10,000 CFM of

ventilation (outside) air to meet code requirements.

A corresponding 10,000 CFM of exhaust air will be

removed from the space. Both air streams have a

static pressure loss or 0.75 “W.C. A Tempeff Dual

Core unit complete with fans has been selected to

assure maximum energy recovery from the space.

The winter outside design air temperature is -4

deg F, and exhaust temperature is 70 deg F. The

summer outside design air temperature is 85 deg F,

and exhaust temperature is 75 deg F. Desired winter

supply temperature is 72 deg F, and desired summer

leaving temperature is 77 deg F. The target winter

temperature efficiency is 90%

3. Sensible Heating and cooling

recovered determined by:

BTUH = (T2-T3) x Airflow x 1.08

Winter:

BTUH = (62.3 – (-4)) x 10,000 CFM x 1.08

BTUH = 716, 040

Thus at -4 deg F the system will recover

716,040 BTU per hour.

Summer:

BTUH = (77-85) x 10,000 CFM x 1.08

BTUH = - 86,400 BTUH

Thus at 85 deg F the system will regain

86,400 BTU per hour of cooling, or 7.2 tons.

4. Determine HP required for supply

and exhaust fans.

We have been given that the ESP for both supply and

exhaust is 0.75” W.C. Since a heating coil has been

added to the supply air stream, the pressure drop

of the coil must be added. Thus the total ESP for

the supply is 0.85” W.C, and total for the exhaust is

0.75” W.C. To be conservative on the supply air side,

1.0” W.C will be used.

Consulting the performance chart at 10,000 CFM

and 1.0 “W.C ESP = 6.27 bhp

Consulting the performance chart at 10,000 CFM

and 0.75 “W.C ESP = 5.71 bhp

Thus a 7.5 hp motor is the minimum allowable motor

size for both supply and exhaust air fans.

Larger sizes are available, contact your local Tempeff representative for more information

All winter efficiencies are calculated using -4 deg F (-20 deg C).

All efficiencies are +/- 5% depending on site conditions

All efficiencies are across entire base unit, including supply fan and motor

HP values shown include core pressure drop, standard 30% (MERV 7) filter and basic cabinet losses.

Add all ancillary coil, filter and other pressure drops to the ESP to use chart.

For unbalanced air streams, contact your local Tempeff representative

For larger ESP values, contact your local Tempeff representative

1.10 UNIT CONTROL FUNCTION

A. Testing Damper Actuators

1. Damper motors can be tested by using the changeover switch S1 in the damper control panel.

2. The normal position of the S1 switch is 0 where the actuators follow the signals from a central control system (BMS)

3. If S1 is in position 1 the damper actuator M7 runs continuously, and in position 2 actuator M6 runs continuously

B. Sequence with the unit controlled by central control system (BMS)

1. When the S2 switch is in position A (automatic) the damper is controlled by the central control system (BMS)

a. Contact1(seefieldwiringdiagram)controlsthewhetherthedamperoperatesornot(contactclosed=operating,opennotoperating)

b. Contact2(seefieldwiringdiagram)controlsthedamperoperatingmode(contactclosed=heatrecovery,open=freecooling)

2. Contact 1 closed and contact 2 open = damper changes position every 3 hours (free cooling)

3. Contact 1 closed and contact 2 closed = damper changes position every 60 seconds (field adjustable) heat recovery

4. Contact 1 open and contact 2 open = the damper is closed

C. Operation of the changeover damper if central control system is not used

1. Set the changeover switch S2 in the M position (manual)

2. Damper is now controlled by the 2 internal thermostats GT1 in the supply air and GT2 in the exhaust air.

GT1 is set to 59 oF (15 oC) and GT2 is set to 68 oF (20 oF).

3. The sequence will now be:

a. If exhaust air < 68 oF (20 oC)=heatrecovery(cyclingevery60seconds)

b. If exhaust air > 68 oF (20 oC)andsupplyair>59oF (15 oC)=freecooling(cyclingevery3hours)

c. If exhaust air > 68 oF (20 oC)andsupplyair<59oF (15 oC)=heatrecoveryuntilsupplyair>59oF (15 oC)

thenitwillreverttofreecoolingmode.

4. When the S2 switch is in position 0 = shut off = all dampers closed.

D. Fans, heating and cooling

1. Starting and stopping of supply and exhaust fans will be by others (central control system)

2. Any type of supplemental heating or cooling of the supply air will be controlled by others (central control system)

Note: In all cases ensure that damper section is first on and last off, (after supply and exhaust blower section) to prevent damage

to internal damper section.

EXECUTIOn2.01 INSTaLLaTION

A. Install in accordance with manufacturer’s Installation & Maintenance instructions.

2.02 ENVIRONMENTaL REQUIREMENTS

A. Do not operate units for any purpose, temporary or permanent, until ductwork is clean,

filters are in place, bearings lubricated, and fan has been test run under observation.

1.06 ELECTRICaL

A. The air handler(s) components shall be CSA, Ul or CE listed as applicable.

B. On rG sizes 1800 through 25000 all controls shall be located on the side of the unit for ease of servicing. Units within this size range which will

1.08 ENERGY RECOVERY

A. Dual Core Energy recovery

1. Unit shall be equipped with Tempeff Dual Core energy recovery technology. The unit shall be 90% temperature efficient (+-5%) in winter

and up to 80% in summer. It shall also provide up to 70% latent recovery. Unit shall accomplish this recovery without a defrost cycle that will

reduce the effectiveness of the device. Devices employing defrost cycles that bypass the heat recovery device, or reduce the effectiveness

are not acceptable. Heat recovery device shall not require frost protection in applications down to -40 degrees. Cores shall be Generation 3,

comprised of precisely corrugated high grade aluminum.

2. Switchover damper section shall be comprised of multi section low leakage dampers operated by electric damper motors complete with

DC braking (pneumatic on sizes rG 33000 and larger). Each damper shall control one of the 4 airways, upper-horizontal, lower-horizontal,

forward-vertical and rear-vertical. Dampers shall be capable of orienting to close off outside air to the building without needing external shut

off dampers. Units employing single blade dampers must include external shut-off dampers. Dampers shall also be capable of orienting

to allow 100% recirculation of air without using heat recovery device for off peak or unoccupied heating modes. Units incapable of these

operations are not acceptable. Damper blades, rods and axles shall be galvanized for long life expectancy.

3. recovery cycles shall be controlled by internal programmed thermostats measuring both supply and exhaust air, and optimizing

performance of both heat recovery and free cooling modes.
