Absorption heat pumps use an ammonia-drinking water absorption cycle, as opposed to a vapor-compression cycle, to transfer heat.

The ammonia condenses at one of many program’s coils to release heat and evaporates at another coil to absorb heat. https://geilebookmarks.com/story20279951/the-smart-trick-of-air-source-heat-pumps-that-nobody-is-discussing
