Question: An air conditioner cools a house at TL = 20C with a maximum of 1.2 kW power input. The house gains 0.6 kW per degree

An air conditioner cools a house at TL = 20°C with a maximum of 1.2 kW power input. The house gains 0.6 kW per degree temperature difference to the ambient and the refrigeration COP is β = 0.6 βCarnot. Find the maximum outside temperature, TH, for which the air conditioner provides sufficient cooling.
