Absorption heat pumps use an ammonia-drinking water absorption cycle, as opposed to a vapor-compression cycle, to transfer heat. Ammonia would be the refrigerant, and drinking water may be the absorber. The ammonia condenses at among the system’s coils to release heat and evaporates at the other coil to absorb heat. https://tbookmark.com/story20266690/the-single-best-strategy-to-use-for-robur-heat-pumps
