Calculate cu ft of occupied space. 1. Multiply number of people times 15 CFM/person. 2. Multiply by recommended air changes per hr (AC/h). 2. Multiply number of bath rooms 20 CFM/each. 3. Divide by 60 minutes per hr to convert to CFM. 3. Add 25 CFM for kitchen. Example: Example: 2000 sq ft with 8 ft ceiling, 0.35 air changes per hr (AC/h) 2 people, 2 baths, 1 kitchen (2000sqftx8ftceilingx0.35AC/h)/60min/h=93.3CFM (2x15)+(2x20)+25=95CFM ERVBBLHA 3 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.

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 pg. 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 ERVBBLHA1200 has an additional cooling load of 5042 Btuh, while the HRV150CFM unit has an additional cooling load of 8437 Btuh. 4 PSYCHROMETRIC CHART Grains of moisturePounds of moisture 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 202525 30 35 40 45 50 55 60 65 70 75 8030 35 40 85 90 95 100 105 45 50 55 60 65 70 75 80 85 90 95 100 105 Enthalpy at saturation, Btu per pound of dry air per pound of dry air 14.0 cu ft 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 per pound of dry air Wet Bulb,Dewpoint orSaturationTemperature F Dry BulbTemperature F .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 1801701601501401301201101009080706050403020100 14.5 cu ft per pound of dry air Below 32uF, properties and enthalpy deviation lines are for ice.
