2. Heat pump and refrigeration cycle - Wikipedia

   en.wikipedia.org/wiki/Heat_pump_and...

   Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]

3. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   Less work is required to move heat than for conversion into heat, and because of this, heat pumps, air conditioners and refrigeration systems can have a coefficient of performance greater than one. The COP is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often ...

4. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   Air-source heat pumps are relatively easy and inexpensive to install, so are the most widely used type. In mild weather, coefficient of performance (COP) may be between 2 and 5, while at temperatures below around −8 °C (18 °F) an air-source heat pump may still achieve a COP of 1 to 4. [25]

5. Thermal efficiency - Wikipedia

   en.wikipedia.org/wiki/Thermal_efficiency

   Heat pumps, refrigerators and air conditioners use work to move heat from a colder to a warmer place, so their function is the opposite of a heat engine. The work energy ( W in ) that is applied to them is converted into heat, and the sum of this energy and the heat energy that is taken up from the cold reservoir ( Q C ) is equal to the ...

   Whereas an air conditioning unit’s only purpose is to cool your home, heat pumps heat and cool the house. Heat pumps simply move air. If you are cooling your home, the pump works the same as an ...
