Question

A heat pump with r134a as the working fluid is used to keep a space at 25c by absorbing heat from geothermal water that enters the evaporator at 50c at a rate of 0.065 kg/s and leaves at 40c. The refrigerant enters the evaporator at 20c with a quality of 23 percent and leaves at the inlet pressure as saturated vapour. The refrigerant loses 300 w of heat to the surroundings as it flows through the compressor and the refrigerant leaves the compressor at 1.4 mpa at the same entropy as the inlet. Determine
