Question details

Question Ref. No: 2909 A heat pump with refrigerant-134a as the working fluid is used to keep a space at 24 oC by absorbing heat from geothermal water that enters the evaporator at 70 0C at a rate of 0.0856 kg/s and leaves at 45 oC Refrigerant enters the evaporator at 2 oC with a quality of 0.86 and leaves at the same pressure as saturated vapor.If the compressor consumes 1.06 kW of power, determine (a) the mass flow rate of the refrigerant, (b) the rate of heat supply, (c) the COP, and (d) the minimum power input to the compressor for the same rate of heat supply. mR (kg/s) Win (kW) COP Win,min (kW) Format:0.2692 Format: 3.06 Format: 6.4475 Format: 4.275
