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 30 min. If the COP of the air-conditioning system is 2.8, using appropriate software, determine the power input required by the air conditioner to cool the house as a function for air conditioner EER ratings in the range of 5 to 15. Discuss your results and include representative costs of air-conditioning units in the EER rating range. Assume the entire mass within the house is equivalent to 800 kg of air for which cv = 0.72 kJ/kgK and cp = 1.0 kJ/kgK
