The vapor compression heat pump system uses R134a as the working fluid. The inlet conditions of the refrigerant to the compressor are 2.4 bar, 0oC and its volumetric flow rate is 0.6 m3 / min. Compression is adiabatic and lasts up to 9 bar and 60oC conditions. From the condenser The exit conditions (from the condenser) are 9 bars of saturated liquid. Under these conditions; a) Calculate the heating capacity of the system in kW. b) Calculate the heating efficiency coefficient (COPIP) of the system. c) Calculate the adiabatic efficiency of the compressor.
