Heat Pump Refrigerants
(refrigerant) any substance used to provide cooling (as in a refrigerator)
(Refrigerant) The liquid used to absorb and transfer heat from one part of the home comfort system to another.
A refrigerant is a substance used in a heat cycle usually including, for enhanced efficiency, a reversible phase change from a gas to a liquid.
A substance used for refrigeration
A device that transfers heat from a colder area to a hotter area by using mechanical energy, as in a refrigerator
apparatus that extracts heat from a liquid that is at a higher temperature than its surroundings; can be used to transfer heat from a reservoir outside in order to heat a building
(Heat pumps) Heat pumps use heat from either the ground or the outside air to heat a building. Ground- and Air- source heat pumps are not completely ‘renewable’ as they require electricity to drive their pumps or compressors.
A heat pump is a machine or device that moves heat from one location (the 'source') at a lower temperature to another location (the 'sink' or 'heat sink') at a higher temperature using mechanical work or a high-temperature heat source.
