EXAMPLE: The heating design temperature for Little Rock, AR is 20_F. The additional heating load of the ERVBBLHA1200 at 20_F is 559 Btuh. This additional load should be taken into consideration when sizing the heating equipment.

To use the cooling load chart, first find the design enthalpy from a psychrometric chart using the design dry bulb and wet bulb temperatures. 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 ERVBBLHA1200 has an additional cooling load of 5042 Btuh, while the HRV1150CFM unit has an additional cooling load of 8437 Btuh. 6 PSYCHOMETRIC CHART .025.024.023.022.021.020.019.018.017.016.015.014.013.012 .95.90.85.80.75.70.65.60.55.50.45.40.35 .011.010.009.008.007.006.005.004.003.002.0010 Sensibleheatfactor Pounds of moistureper pound of dry air 7 8 9 10 11 12 32 33 34 35 36 37 38 39 40 41 42 43 44 45 47 48 49 46 27 28 29 30 31 19 20 21 22 23 24 25 26 12 13 14 15 16 17 18 Wet Bulb, Dewpoint orSaturationTemperature FDry BulbTemperature F 20Below 32° F, properties and enthalpy deviation lines are for ice. 2525 30 35 40 45 50 55 60 65 70 75 80 30 35 40 85 90 95 100 105 1801701601501401301201101009080706050403020100 45 50 55 60 65 70 75 80 85 90 95 100 105 110 Enthalpy at saturation, Btu per pound of dry air Grains of moistureper pound of dry air 14.0 cu ft 14.5 cu ft per pound of dry air 13.5 cu ft 13.0 cu ft 12.5 cu ft 90% Relative Humidity80%70% 60% 50% 40% 30% 20% 10% -.02 BTU -.01 BTU -.02 Btu -.04 Btu -.06 Btu -.08 Btu +0.1 Btu+0.2 Btu+0.3 Btu+0.4 Btu +0.5 Btu 80%60%40%20% Btu per pound of dry air -0.3 Btu Enthalpy deviation A989394ERV/ HRV.025.024.023.022.021.020.019.018.017.016.015.014.013.012 .95.90.85.80.75.70.65.60.55.50.45.40.35 .011.010.009.008.007.006.005.004.003.002.0010 Sensibleheatfactor Pounds of moistureper pound of dry air 7 8 9 10 11 12 32 33 34 35 36 37 38 39 40 41 42 43 44 45 47 48 49 46 27 28 29 30 31 19 20 21 22 23 24 25 26 12 13 14 15 16 17 18 Wet Bulb, Dewpoint orSaturationTemperature FDry BulbTemperature F 20Below 32° F, properties and enthalpy deviation lines are for ice. 2525 30 35 40 45 50 55 60 65 70 75 80 30 35 40 85 90 95 100 105 1801701601501401301201101009080706050403020100 45 50 55 60 65 70 75 80 85 90 95 100 105 110 Enthalpy at saturation, Btu per pound of dry air Grains of moistureper pound of dry air 14.0 cu ft 14.5 cu ft per pound of dry air 13.5 cu ft 13.0 cu ft 12.5 cu ft 90% Relative Humidity80%70% 60% 50% 40% 30% 20% 10% -.02 BTU -.01 BTU -.02 Btu -.04 Btu -.06 Btu -.08 Btu +0.1 Btu+0.2 Btu+0.3 Btu+0.4 Btu +0.5 Btu 80%60%40%20% Btu per pound of dry air -0.3 Btu Enthalpy deviation A989394ERV/ HRV 7 8 Ventilator installed with forced air system A99297 Ventilator installed with independent air distribution A99298 ERV / HRV ACCESSORIES VENTILATOR ACCESSORY NUMBER NOMENCLATURE 1 2 3 4 5 6 7 8 9 10 11 12 K V B C N 0 1 0 1 B B S Product KV - --Ventilator Accessory Kit Series A - --Original Series B - --Second Series Type AC01 - --Accessory CN01 - --Control TM01 - --Timer AC01 - --Accessory Package Quantity 01 - --Single Pack DESCRIPTION Automatic Wall Control Basic Wall Control Latent Wall Control Bryant OneTouch Control Standard HRV Control Exterior Intake and Exhaust Hood Airflow Measuring Kit 20 Minute Push Button Timer 60 Minute Timer 6 in.
