Absorption heat pumps use an ammonia-h2o absorption cycle, in lieu of a vapor-compression cycle, to transfer heat. Ammonia could be the refrigerant, and drinking water may be the absorber. The ammonia condenses at among the method’s coils to launch heat and evaporates at the other coil to absorb heat.
