Question

Answer it

A Carnot refrigeration cycle absorbs heat at 270 K and rejects it at 300 K. 1. Calculate the coefficient of performance of this refrigeration cycle. 2. If the cycle is absorbing 1130 kJ/min at 270 K, how many kJ of work is required per second ? 3. If the Carnot heat pump operates between the same temperatures as the abov refrigeration cycle, what is the coefficient of performance ? 4. How many kJ/min will the heat pump deliver at 300 K if it absorbs 1130 kJ/min at 270 K
