Refrigerant-134a enters the condenser of a residential heat pump at 900 kPa and 65oC at a rate of 0.018 kg/s and leaves at 750 kPa subcooled by 2oC. The refrigerant enters the compressor at 200 kPa superheated by 3oC. Determine (a) the isentropic efficiency of the compressor in decimal (up to two decimals), (b) the rate of heat supplied to the heated room, and (c) the COP of the heat pump. Also determine (d) the COP if this heat pump operated on the ideal vapour compression cycle between the pressure limits of 200 and 900 kPa
