A building is being heated through the help of a Carnot heat pump and is required to be maintained at 20 degrees C always. When the temp outside drops to -10 degrees C, the rate at which heat is lost from the building is 25kW. What is the minimum electrical power required (kW) in order to drive the heat pump?

A heat pump is used to extract heat from the outside atmosphere to heat the inside of a building. On a day when the outside air temperature is Tc°C, the heat pump is operating to a COP of 2.7, maintaining the inside temperature of the building at Th°C.

heat pump with a coefficient of performance of 2.5 supplies energy to a house at a rate of 60,000 Btu/h. Determine (a) the electric pwer drawn by the heat pump and (b) the rate of heat absoption from the outside air.
The performance of a heat pump degrades (i.e., its COP decreases) as the temperature of the heat source decreases. This makes using heat pumps at locations with severe weather conditions unattractive. Consider a house that is heated and maintained at 20°C by a heat pump during the winter. What is the maximum COP for this heat pump if heat is extracted from the outdoor air at 10°C?
