Question

Carnot refrigeration cycle absorbs heat at 270 K and rejects heat at 300 K. (a) Calculate the coefficient of performance of this refrigeration cycle. (b) If the cycle is absorbing 1130 kJ/min at 270 K, how many kJ of work is required per second. (c) If the Carnot heat pump operates between the same temperatures as the above refrigeration cycle, what is the coefficient of performance. (d) How many kJ/min will the heat pump deliver at 300 K if it absorbs 1130 kJ/min at 270 K.
