Step 1
- Heat removed from the refrigerator, \( Q_L = 360 \, \text{kJ/min} \). - Power input to the refrigerator, \( W_{\text{in}} = 2 \, \text{kW} \). Show more…

The food compartment of a refrigerator is maintained at 4°C by removing heat from it at a rate of 360 kJ/min. If the required power input to the refrigerator is 2 kW, (i) determine the rate of heat rejection to the room that houses the refrigerator. (ii) Determine the higher temperature of the system.

A Carnot refrigerator operates in a room in which the temperature is $22^{\circ} \mathrm{C}$ and consumes $2 \mathrm{kW}$ of power when operating. If the food compartment of the refrigerator is to be maintained at $3^{\circ} \mathrm{C}$, determine the rate of heat removal from the food compartment.
Carnot Refrigerator A Carnot refrigerator does $200 \mathrm{~J}$ of work to remove $600 \mathrm{~J}$ of thermal energy from its cold compartment. (a) What is the refrigerator's coefficient of performance? (b) How much thermal energy per cycle is exhausted to the kitchen?
