Dual Core Energy Recovery Temperature 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. 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. 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 0 F (-40 0 C). Thus owners of Tempeff equipment can rest assured that they will enjoy the high performance of their system for a long time.

Ancillary outdoor and exhaust air dampers recommended with this option. Contact your local Tempeff representative for more available options. An ideal solution. 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. 1 2

Tempeff Dual Core Energy Recovery Operation 3 Cycling for Recovery PHASE 2 Simplest Form A typical Tempeff Dual Core unit contains 2 energy cores (A & B), special change over damper, an exhaust fan, and a supply fan. Exhaust Fan Atmosphere Energy Core B damper Energy Core A Atmosphere Supply fan After 60 seconds, the dampers reposition. Now Exhaust AIR 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 outdoor AIR 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 Energy Core B 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.

Selection Guide 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 (Dry Bulb) T2 = Temperature of (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. 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% Determine: 1. Desired Tempeff Dual Core model 2. 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. temperature is determined by: T2 = Et(T1-T3) + T3 Where: Et = Temperature efficiency T1 = Temperature of (Dry Bulb) T2 = Temperature of (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. 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. 5 6

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. Contact 1 (see field wiring diagram) controls the whether the damper operates or not (contact closed = operating, open not operating) b. Contact 2 (see field wiring diagram) controls the damper operating mode (contact closed = heat recovery, open = free cooling) 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 o F (15 o C) and GT2 is set to 68 o F (20 o F). 3. The sequence will now be: a. If exhaust air < 68 o F (20 o C) = heat recovery (cycling every 60 seconds) b. If exhaust air > 68 o F (20 o C) and supply air > 59 o F (15 o C) = free cooling (cycling every 3 hours) c. If exhaust air > 68 o F (20 o C) and supply air < 59 o F (15 o C) = heat recovery until supply air > 59 o F (15 o C) then it will revert to free cooling mode. 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 is first on and last off, (after supply and exhaust blower ) to prevent damage to internal damper. EXECUTION 2.01 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. 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. 1.09 EXTERNAL DAMPERS [Damper Leakage: Leakage rate shall be less than two tenths of one percent leakage at 2 inches static pressure differential.
