Air Heat Pumps

Air to water heat pumps employ the dynamics of the vapour/compression cycle used for many years in the basic refrigeration process found within a domestic fridge. A low pressure, low boiling point liquid (refrigerant) is exposed to a higher temperature in the coil of the evaporator. The vapour boils off to a gas and in doing so, absorbs energy. The refrigerant gas is then compressed to a higher pressure and temperature before passing through a heat exchanger where it gives its heat energy to water. The heated water is then delivered to a cylinder or heating system. After passing through the heat exchanger the refrigerant condenses back into a liquid before starting the process again.
