Hi
How to determine the return air flow rate and exhaust air flow rate of AHU? OA & supply air shall be calculated. all I know return has to be same as supply and OA shall be subtracted, but I found in other designs that return is taken 2-10% less the the supply rate ,can anyone please tell explain Why?
