지열 펌프 지열 히트 펌프(GSHP)는 땅속의 열을 이용하여 냉난방을 조절하는 중앙 난방 및 냉방 시스템입니다. 겨울에는 지표면 아래의 비교적 일정한 온도를 열원으로, 여름에는 열 흡수원으로 활용합니다. 이러한 높은 열 관성 덕분에 GSHP는 높은 효율을 자랑하며, 성능 계수(COP) 또한 높고 안정적입니다.

지열 펌프 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 폴리에틸렌, 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.
