Refrigerants are used in buildings:
*For heating, ventilation and air conditioning (HVAC) systems.
*To provide cooling for refrigeration.
*To provide cooling for industrial processes.

They provide cooling in a process that is essentially the same as that used in domestic fridges, based on either compression or absorption. Compression refrigeration is more common than absorption refrigeration.

In absorption refrigeration systems, a refrigerant that boils at low temperature and pressure is absorbed in a solution which is then heated in a ‘generator’ so that the refrigerant evaporates again, but this time at a higher pressure and temperature.
