In the course of the hotter months, air-resource warmth pumps work similarly to central air conditioners by making use of a refrigerant to extract heat from indoors and expelling it outdoors in the compressor. Whilst working through the cold-weather conditions months, heat pumps make the most of a reversing valve to modify from cooling to heating modes to function in reverse.
During the refrigeration cycle, the refrigerant would be the auto that carries heat from indoors to the skin for the duration of cooling and vice versa throughout heating.
