NC-2009 EAp2:Minimum Energy Performance
90.1 AppG G3.1.2.8 says the return/relief fan should be sized for max (SA-OA, 90%*SA) [cfm]. But in table 1.4. the allowable fan power is only based on the supply fan power. If I calculate the return/relief fan power based onG3.1.2.8, it will exceed the allowable fan power calculated by 1.4. So does anyone have a good approach how to deal with this?
