A house is air conditioned using solar energy. Solar radiation heats a pressurized tank such that the temperature is maintained at 175oC. 1500 kJ must be extracted from the house to maintain the temperature at 24oC when the ambient temperature is 33oC.
Determine the minimum amount of heat that must be extracted from the tank of water by any device built to accomplish the required cooling of the house
