地源热泵，是指利用浅层地热能为建筑供冷、采暖或制生活热水的热泵装置。¹⁾

冬季：

地源热泵将地热能传递入建筑以为建筑采暖。
Geothermal heat pumps transfer underground heat into buildings to provide heating.

夏季：

地源热泵将热能从建筑传递入地下以为建筑制冷。
Geothermal heat pumps transfer heat from buildings into the ground to provide cooling.

1、垂直埋管地源热泵Vertical Closed-Loop

一对底部装配有特殊U型的管道放置在100至400英尺深的孔洞中。
A pair of pipes with a special U-bend assembly at the bottom is placed into bore holes from 100 to 400 feet deep

2、水平埋管地源热泵Horizontal Closed-Loop

管道阵列安装在沟槽中，切割深度为3到5英尺，长度达数百英尺。
A piping array is installed in trenches cut 3 to 5 feet deep and hundreds of feet in length

3、地表水源热泵Surface Water Closed-Loop

管道阵列被淹没在池塘或湖泊中，至少8英尺深
A piping array is submerged in a pond or lake at least 8 feet deep

4、地下水源热泵Ground Water Open-Loop

井水从地下含水层通过地热泵抽水，然后返回含水层或排放到地表。
Well water from an underground aquifer is pumped through the geothermal heat pump and then returned to the aquifer or discharged to the surface
