A heat engine running between a pit at 15 degree and an energy storage that is 50 times warmer than the pit works. 2/3 of the generated power is used to run the Carnot heat pump, which heats an home. Heat pump draws heat from the air at 4 degree and keeps the home at 15 degree. So the heat loss of home is 61000 kJ / h; a. Describe the system by drawing it schematically. b. Calculate the minimum heat that should be transferred to the heat engine.

An air conditioning unit works by taking heat out of a room. As the refrigerant gas expands in the cooling coils, it absorbs heat from the circulating air in the room. This heat is then released as the refrigerant is compressed by the part of the unit that is directed out of the room. The unit serves like a heat pump for the room. Since a refrigerator works in a similar manner, can t also be used to maintain a cool temperature inside a room? Justify your answer.
