Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles...

A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated...

radiation, and their use as a refrigerant worldwide was curtailed in the Montreal Protocol of 1987. In the last century, refrigeration allowed new settlement...

heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. A heat pump...

concept was similar to an early refrigeration device known as an Icyball. Common absorption refrigerators use a refrigerant with a very low boiling point...

such as ULT freezers. In a cascade refrigeration system, two or more vapor-compression cycles with different refrigerants are used. The evaporation-condensation...

Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique can be used to attain extremely low temperatures, as...

Refrigerant reclamation is the act of processing used refrigerant gas which has previously been used in some type of refrigeration loop such that it meets...

absorption refrigeration (note that the second letter is different). The difference is that in adsorption refrigeration, the refrigerant or adsorbate...

as a refrigerant. Propane that is supplied for general use – such as in barbeques and patio heaters – is not suitable for use in refrigeration systems...
