Heat Pump Efficiency: Equation & Formula Linquip

WebCOP is the ration of the heat brought in from the outside with a heat pump to the heat that would have been produced if the heat pumps power were to just create resistance heating. A good air exchange heat pump has a COP of 4 or more. Meaning that it can bring in 4 times the heat that it could have made with a given amount of energy. Anot WebHence, a higher COP means that the heat pump provides the same work with less energy. Therefore, the higher the COP, the higher the efficiency. Efficiency The efficiency of a reverse heat engine is the amount of heat transfer that is actually converted into work. This is determined by dividing work by the heat transfer Q H. WebMar 17, 2015 · The maximum possible COP, COPmax, for a heat pump is Th/(Th - Tc), and for a refrigerator it is Tc/(Th - Tc).

A heat pump is a device that can provide heat to a building by transferring thermal energy from the outside using a refrigeration cycle. Many heat pumps can also operate in the opposite direction, cooling the building by removing heat from the enclosed space and rejecting it outside. Units that only provide cooling are called air conditioners.
