Q2: A dense closed cycle refrigeration system working between 4 bar and 16 bar. The air temperature after heat rejection to surrounding is 37°C and air temperature at exit of refrigerator is 7°C. The mechanical efficiency of turbine and compressor 0.85 and 0.8 respectively. Determine compressor and turbine work per TR; C.O.P; and power per TR. Take y=1.4 and cp=1.005 kJ/kg.K. Assume the compression and expansion are isentropic.
