Refrigerant 134a enters a compressor operating at steady state as saturated vapor at -4 °C and exits at a pressure of 1.4 MPa. The isentropic compressor efficiency is 85%. Heat transfer between the compressor and its surroundings can be ignored. Kinetic and potential energy effects are also negligible. Determine (a) the exit temperature, in °C. (b) the work input, in kJ per kg of refrigerant flowing.
