Absorption heat pumps use an ammonia-water absorption cycle, rather than a vapor-compression cycle, to transfer heat. Ammonia could be the refrigerant, and h2o would be the absorber. The ammonia condenses at among the process’s coils to release heat and evaporates at the other coil to soak up heat.
