In an air conditioning system, refrigerant R-134a entersthrottling valve before enters an adiabatic, ideal heat exchanger.R-134a enters throttling valve at 0.9 MPa as saturated liquid, andit exits the heat exchanger as saturated vapor at 2oC.At the heat exchanger, the heat exchanges between the refrigerantand air. The air enters at 25oC and exits at20oC, with volumetric flowrate of 1 m3/s andat pressure 101 kPa. Determine:
