地源热泵 泵 system capitalizes on the stable temperature of the earth a few meters below the surface, which remains relatively constant year-round (typically 10-16°C or 50-60°F) regardless of the ambient air temperature. This provides a significant efficiency advantage over conventional air-source heat pumps, which must exchange heat with outdoor air that can be extremely cold in winter and hot in summer.
The system consists of three main parts: the heat pump unit itself, a liquid heat exchange medium (the ‘ground loop’), and an air delivery system (ductwork). The ground loop is a series of pipes, commonly made of high-density 聚乙烯, buried in the ground near the building. It can be installed in horizontal trenches or vertical boreholes. A water or antifreeze solution is circulated through these pipes to absorb heat from the ground in winter and transfer it to the heat pump. The heat pump then concentrates this heat and delivers it to the building. In summer, the process is reversed: the heat pump extracts heat from the building’s interior and transfers it to the fluid in the ground loop, which then dissipates it into the cooler earth. Because the temperature difference between the source/sink (the ground) and the desired indoor temperature is smaller and more stable, the GSHP operates with a much higher and more consistent COP than its air-source counterparts.
