Air-Source Heat Pumps | Department of Energy
An air-source heat pump can provide efficient heating and cooling for your home. When properly installed, an air-source heat pump can deliver up to three times more heat energy to a home than the electrical energy it consumes. This is possible because a heat pump transfers heat rather than converting it from a fuel like combustion heating systems.
Heat pumps and energy transfer — Science Learning Hub
Q h = Q c + W. For example, in the operation of a commercial heat pump, the thermal energy transferred to the inside of the building (Q h) was found to be 80 kJ, whereas the thermal energy extracted from the cold outside air was 60 kJ. To achieve this, the amount of electrical work (W) needed from a compressor was found to be 20 kJ.
