A heat pump is used to heat a building. The external temperature is lower than the internal temperature. The pump's coefficient of performance is 3.70, and the heat pump delivers 7.27 MJ as heat to the building each hour. If the heat pump is a Carnot engine working in reverse, at what rate must work be done to run it
Answers: 3
), no unit, of a Carnot's heat pump is:
(1)
- Heat received by the building, measured in megajoules. 
- Work needed to run the heat pump, measured in megajoules. 
and 
, then the amount needed by the heat pump each hour is:
