Absorption heat pumps use an ammonia-h2o absorption cycle, instead of a vapor-compression cycle, to transfer heat. Ammonia will be the refrigerant, and water will be the absorber. The ammonia condenses at one of many process’s coils to launch heat and evaporates at the opposite coil to absorb heat. Benefit from https://bookmarkick.com/story20391348/everything-about-heat-pumps
