Absorption heat pumps use an ammonia-h2o absorption cycle, instead of a vapor-compression cycle, to transfer heat. Ammonia would be the refrigerant, and h2o will be the absorber. The ammonia condenses at among the list of process’s coils to release heat and evaporates at another coil to absorb heat.
