When a man returns to his well-sealed house on a summer day, he finds that the house is at 32°C.
He turns on the air conditioner, which cools the entire house to 20°C in 15 min. If the COP of the air-conditioning system is 2.5, determine the power drawn by the air conditioner. Assume the entire mass within the house is equivalent to 800 kg of air for which cv = 0.72 kJ/kg €¢ °C and cp = 1.0 kJ/kg €¢ °C.
