3. Heat pump - Wikipedia

   en.wikipedia.org/wiki/Heat_pump

   In general, heat pumps work most efficiently (that is, the heat output produced for a given energy input) when the difference between the heat source and the heat sink is small. When using a heat pump for space or water heating, therefore, the heat pump will be most efficient in mild conditions, and decline in efficiency on very cold days.

   An air source heat pump can be used to air condition the building during hot weather, and to warm the building using heat extracted from outdoor air in cold weather. Air-source heat pumps are generally uneconomic for outdoor temperatures much below freezing. In colder climates, geothermal heat pumps can be used to extract heat from the ground ...

6. Absorption heat pump - Wikipedia

   en.wikipedia.org/wiki/Absorption_heat_pump

   The absorption heat pump can be used as a cooler during summer while, during winter, it can be used on heat pump or heat transformer mode according to the available heat source. [6] The performance of the absorption heat pump is indicated by the coefficient of performance (COP). The COP is the ratio of the removed (for refrigeration) or ...
