Question
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
