   en.wikipedia.org/wiki/Air_source_heat_pump

   An air source heat pump (ASHP) is a heat pump that can absorb heat from air outside a building and release it inside; it uses the same vapor-compression refrigeration process and much the same equipment as an air conditioner, but in the opposite direction. ASHPs are the most common type of heat pump and, usually being smaller, tend to be used ...

   Air source heat pumps are the most common models, while other types include ground source heat pumps, water source heat pumps and exhaust air heat pumps. [3] Large-scale heat pumps are also used in district heating systems. [4] The efficiency of a heat pump is expressed as a coefficient of performance (COP), or seasonal coefficient of ...

6. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Ground source heat pumps provide a reliable source of consistent thermal energy when buried 10–20 m below the ground surface. The ground temperature is warmer than the ambient air in winter and cooler than the ambient air in summer, providing both a heat source and a heat sink. It was found that in February, the coldest month in the climate ...
