Absorption heat pumps use an ammonia-water absorption cycle, instead of a vapor-compression cycle, to transfer heat. Ammonia will be the refrigerant, and drinking water is the absorber. The ammonia condenses at one of the technique’s coils to release heat and evaporates at the other coil to soak up heat.
