Calculate cubic feet of occupied space 2. Multiply by recommended air changes per hour (AC/h) 3. Divide by 60 minutes per hour to convert to CFM Example: 2000 sq ft with 8 ft ceiling 0.35 air changes per hour (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 2,322 2. Multiply number of bathrooms times 20 CFM/each OutsideTemp°FHeat Load (BTUh) @ Inside Design Temp 72°FHRVBBLHA1150 –25 4,688 –20 4,466 –15 4,598 –10 4,334 –5 4,069 0 3,805 5 3,541 10 3,502 15 3,220 20 2,938 25 2,950 30 2,636 3540 2,009 3. Add25CFM for kitchen The heating load chart shows the heating loads in BTUh for a range of winter design temperatures for each model of ventilator. Example: 2 people EXAMPLE: The heating design temperature for Milwaukee, 2 bathrooms WI, is - --4_F.At - --5_F, the additional heating load of the 1 kitchen HRVBBLHA1250 is 8417 BTUh. This additional load should be taken into consideration when sizing the heating equipment. (2 x 15) + (2 x 20) + 25 = 95 CFM 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. 7 COOLING LOAD BTU OutsideCoolingLoad(BTUh)@InsideDesignTemp75°Fand50%RelativeHumidityOutsideEnthalpyBTU/lbHRVBBLHA1150HRVBBLHA1250306701,071311,0901,741321,5092,411331,9283,080342,3473,750352,7664,419363,1855,089373,6045,759384,0236,428394,4427,098404,8617,767415,28042HRV 8,437 5,699 9,107 The cooling load chart shows the loads in BTUh also. 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 following psychrometric chart.) The cooling load can then be found for a range of enthalpies for each ventilator. EXAMPLE: The cooling design dry bulb temperature for Milwaukee, WI, is 87_F and the average wet bulb at that temperature is 73_F. On the psychrometric chart the enthalpy is about 37.7 BTU/lb of dry air which will round up to 38 BTU/lb of dry air. In the left column, at 38 BTU/lb the HRVBBLHA1250 would have an additional cooling load of 6428 BTUh. This additional load should be taken into account when sizing the air cooling equipment. 8 Psychrometricchart.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 1...
