1 out of 3 attempts When a man returns to his well-sealed house on a summer day, he finds that the house is at 35°C. He turns on the air conditioner, which cools the entire house to 20°C in 28 min. If the COP of the air-conditioning system is 1.8, determine the power drawn by the air conditioner. Assume the entire mass within the house is equivalent to870 kg of air for which cv = 0.72 kJ/kg-°C and c Cp W net,in = 1.0 kJ/kg-°C. kW 35°C 20°C A/C
