A vapor compression refrigeration cycle is used. The working fluid is R134a. The fluid at the compressor inlet is a superheated vapor with a pressure p1 = 200 Kpa and a temperature T1 = 10°C. The compressor pressure ratio p2/p1 = 8, the fluid exits the condenser as a saturated liquid, and the mass flow rate is 0.8 kg/sec. The isentropic efficiency of the compressor work input is 0.65. Assume that the pressure drops in the evaporator and condenser are negligible.
