Refrigeration cycle heat pump

WebThe difference in absorption heat pumps is that the evaporated ammonia pressure is not increased by a compressor. Instead, the ammonia is absorbed into water where a relatively low-power pump can then pump the solution to a higher pressure. The problem is then removing the ammonia from the water, and that's where the heat source comes in. WebThe heat pump gathers heat from the surrounding air, and through the refrigeration cycle, deposits the heat into water at a useable temperature. This principle of moving heat with a heat pump, rather than generating it …
