Q1 A Carnot refrigeration cycle absorbs heat at -8°C and rejects heat at 55°C. (a) If the heat rejection rate is 30 kW, calculate the heat extraction rate, the work input, and the COP of the refrigeration cycle. (b) If the cycle operates as a heat pump calculate the COP of the cycle. [Answers: (a) 24.24 kW, 5.76 kW, 4.2, (b) 5.2]
