In fact, some components of ground-source heat pumps can last even longer. Since the ground and air outside always contain some heat, a heat pump can supply heat to a house even on cold winter days. 506 0 obj <>stream %%EOF A compressor circulates a refrigerant that absorbs and releases heat as it travels between these two units. A typical heat pump consists of two parts: an indoor unit called an air handler and an outdoor unit similar to an air output unit. The compressor is driven by a heat engine with a thermal efficiency of 40%. Absorption heat pumps are essentially air-source heat pumps driven not by electricity, but by a heat source such as natural gas, propane, solar-heated water, or geothermal-heated water. In this way, without applying heat, the work done on the fluid through the pump raises the internal energy of the fluid from U 1 to U 2. On the horizontal axis enthalpy (h) is shown.
