How air/air and air/water heat pumps work
Air-to-air and air-to-water heat pumps use outside air as an energy source to heat or cool buildings. In both systems, an evaporator extracts heat from the outside air, which is then raised to a higher temperature level via a refrigerant cycle compression process. Air-to-air units transfer the extracted heat directly to the room air, usually via an indoor unit with a fan. Air-to-water systems transfer the thermal energy to a water-based system, such as underfloor heating, radiators, or a hot water storage tank, and thus integrate seamlessly into existing building services.
