	Absorption heat pumps work on a similar basis, with a refrigerant that boils at low temperature and pressure, however, in this case, the refrigerant gas (generally ammonia) is then absorbed in a solution (the ‘absorber’, generally water) which is then heated in the ‘generator’ so that the refrigerant evaporates again, but this time at a higher pressure and temperature. It is then condensed through a heat exchanger, heating ‘cool’ return water from the building, and the process then begins again.
