1. The heat absorption and rejection temperatures of a Carnot refrigeration cycle are -8°C and 36°C, respectively. The rate of heat absorption is 28 kW. A. Calculate the COP of the refrigeration cycle. B. Calculate the power input to the cycle in kW. C. If a Carnot heat pump operating between the same temperatures absorb 18 kW from the cold region, calculate the rate of heat supply to the hot region in kW. D. Calculate the COP of the heat pump.
