1. The coefficient of performance of a refrigerator is 2.45. It absorbsabout13 kJ of heat from the cold reservoir. How much mechanical energy is required to operate the refrigerator? 2. How much work is done if a Carnot refrigerator transfers 5 BTU of heat from its interior at 35°F to the outside air at 80°F? 3. The coefficient of performance of an air conditioner is 2.6 and uses 1,000 W of electrical power. How much heat does the air-conditioner remove from the room in one minute? How much heat does the air-conditioner deliver to the hot outside air in one minute? 4. An air conditioner absorbs 85 kJ of heat per minute from the inside room and at the same time deposits 120k] of heat into the outside air. What is the power consumption of the system? What is the energy efficiency rating? 5. In each cycle, a refrigerator absorbs 24 BTU of heat from the cold reservoir. The EER is 8.9.What is the mechanical energy required in each cycle to operate the refrigerator? How much is the discarded heat to the high temperature reservoir?
