1 ENERGY RECOVERY VENTILATORS ERVB The Energy Recovery Ventilator (ERV) offered by Bryant is the finest unit on the market today. The ERVB provides efficient and cost-effective heat recovery when needed most. The ERV is equipped with a special energy recovery core which exchanges both sensible and latent heat with the fresh incoming air. The ability to transfer moisture however, makes the core sensitive to cold outdoor air in winter time. We recommend that the unit should not be installed where the winter design temperature is 15 F ( 10 C) for more than 3 days. When the outdoor air temperature falls to 15 F ( 10 C), the ERV will stop running for three hours. At the end of the three hours, the ERV will check the outdoor temperature. If the temperature outside is warmer than 15 F ( 10 C), the ERV will operate according to the wall control selection. If the outdoor temperature is still too cold, the ERV will remain off for another three hours and check the temperature later. Unlike rotary wheel heat exchangers which mix air streams, these cross flow or counterflow heat exchangers ensure that there is no mixing of the stale air with the fresh air. A filter installed on the incoming outdoor air stream removes large airborne particles from the intake air before they enter the heat exchanger and reduces the maintenance required. The unit s acoustically engineered design makes it the quietest on the market and ensures that comfort is felt, not heard. Unlatching 2 suitcase style latches allows easy removal of the filters and core for cleaning. FEATURES Cross flow total energy exchanger Two filters on indoor and outdoor air streams to protect the ERV core Acoustical design No-tools maintenance Form No. PDS ERV.64.1

Can be used instead of Continuous Mode if the humidity level in the house is too high for continuous ventilation. Low Mode (Continuous) Provides ventilation at high speed when the humidity level in the house is below the setpoint. As the humidity level in the house rises above the setpoint, the unit will continue to deliver air at low speed. 3

METHODS TO SIZE ERV S METHOD 1 1. Calculate cu ft of occupied space. 2. Multiply by recommended air changes per hr (AC/h). 3. Divide by 60 minutes per hr to convert to CFM. EXAMPLE: 2000 sq ft with 8 ft ceiling 0.35 air changes per hr (AC/h) (2000 sq ft x 8 ft ceiling x 0.35 AC/h) / 60 min/h = 93.3 CFM METHOD 2 1. Multiply number of people times 15 CFM/person. 2. Multiply number of bath rooms 20 CFM/each. 3. Add 25 CFM for kitchen. EXAMPLE: 2 people 2 baths 1 kitchen (2 x 15) + (2 x 20) + 25 = 95 CFM 5

6 ADDITIONAL HEATING AND COOLING LOAD CHARTS Although the ventilators process the outside air before it enters the home, additional heating and cooling loads need to be considered. Outside Temp F HEATING LOAD BTU Heat Load Inside Design Temp 72 F ERV The heating load chart shows the heating loads in Btuh for a range of winter design temperatures for each model of ventilator. EXAMPLE: The heating design temperature for Little Rock, AR is 20 F. The additional heating load of the ERVBBLHU1200 at 20 F is 5669 Btuh. This additional load should be taken into consideration when sizing the heating equipment. COOLING LOADS BTU Outside Cooling Load Inside Design Temp Enthalpy 75 F and 50% Relative Humidity Btu/lb ERV150 ERV The cooling load chart shows loads in Btuh as well. To use the cooling load chart, first find the design enthalpy from a psychrometric chart using the design dry bulb and wet bulb temperatures. (See page 7.) The cooling load can then be found for a range of enthalpies for each ventilator. EXAMPLE: The design dry bulb temperature for Miami is 90 F and the average wet bulb at that temperature is 77 F. Using the psychrometric chart, the enthalpy is about 40.5 Btu per pound (Btu/lb) of dry air, which would round up to 41 Btu/lb dry air. In the left column, at 41 Btu/lb dry air, the ERVBBLHU1200 has an additional cooling load of 5042 Btuh, while the HRVBBLHU1150 has an additional cooling load of 8437 Btuh. 6
