In vapour compression refrigeration system, if the evaporator temperature and the condenser temperatures are -13°C and 37°C respectively, the Carnot COP will be________________?
Correct answer: A. 5.2
- A. 5.2
- B. 6.2
- C. 0.168
- D. Data insufficient, can't be found out
Explanation
For a Carnot refrigerator, COP = T_L/(T_H − T_L), using absolute temperatures. Thus COP = 260.15/(310.15 − 260.15) ≈ 5.2.
