Question

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.

Answer 1

In this setup the low temperature space is the house and the high temperature space is the ambient. The heat pump must remove the gain or leak heat transfer to keep it at a constant temperature.

Here: TL = Thouse TH = Tamb
