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.

Question

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.
