An air conditioner on a summer day removes heat steadily from a house at a rate of 750 kJ/min while drawing electric power at a rate of 5.25 kW. Please answer the following. a. Create a schematic representation of the air conditioning system under consideration. b. Determine the COP of this air conditioner and the rate of heat transfer to the outside air. c. Now winter has come, and the owner decides to use the equipment as heat pump to warm the house. Because the house is not perfectly insulated, and the outside temperature is 0°C the estimated rate of heat transfer loss rate from the house to the surroundings is equal to 1200 kJ/min. Will the air conditioning unit operating as heat pump satisfy the required heating if the electrical power drawn is 5.25 kW? Explain how you arrived at the answer. d. If the heat pump would operate as a Carnot Heat Pump and the indoor temperature is 25°C while the outside temperature is 0°C, compute the COP.

Question

An air conditioner on a summer day removes heat steadily from a house at a rate of 750 kJ/min while
drawing electric power at a rate of 5.25 kW. Please answer the following.
a. Create a schematic representation of the air conditioning system under consideration.
b. Determine the COP of this air conditioner and the rate of heat transfer to the outside air.
c. Now winter has come, and the owner decides to use the equipment as heat pump to warm the
house. Because the house is not perfectly insulated, and the outside temperature is 0°C the
estimated rate of heat transfer loss rate from the house to the surroundings is equal to 1200
kJ/min. Will the air conditioning unit operating as heat pump satisfy the required heating if the
electrical power drawn is 5.25 kW? Explain how you arrived at the answer.
d. If the heat pump would operate as a Carnot Heat Pump and the indoor temperature is 25°C
while the outside temperature is 0°C, compute the COP.
