An automobile air conditioner uses refrigerant-134aas the cooling fluid. The evaporator operates at 275 kPagauge and the condenser operates at 1.7 MPa gage. The compressorrequires a power input of 6 kW and has an isentropicefficiency of 85 percent. Atmospheric air at 22°C and 50 percentrelative humidity enters the evaporator and leaves at 8°Cand 90 percent relative humidity. Determine the volume flowrate of the atmospheric air entering the evaporator of the airconditioner, in m3/min.
