5. Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 50C at a rate of 0.022 kg/s and leaves at 750 kPa, subcooled by 3C. The refrigerant enters the compressor at 200 kPa superheated by 4C. Disregarding any heat transfer and pressure drops in the connecting lines between the components, (a) Draw T-S and P-H diagram of the cycle with respect to saturation lines, [4 marks], And determine: (b) The rate of heat removal from the refrigerated space and the power input to the compressor, (c) The isentropic efficiency of the compressor, (d) The COP of the refrigerator, [4 marks], [4 marks], [4 marks], (e) The COP of a reversed Carnot cycle is operating between the same saturation temperatures, [4 marks].
