An air conditioner is used to cool a house. When the outside air temperature is 306K and the inside is maintained at 295K, the air conditioner must provide 17 kW of cooling. a. What is the minimum electric power (kW) required to operate the air conditioner? b. What is the rate of heat transfer from the air conditioner? c. What is the COP for an ideal air conditioner operating between these temperatures?
