土壤源熱泵以大地作為熱源和熱匯，熱泵的換熱器埋于地下，與大地進行冷熱交換。土壤源熱泵系統(tǒng)主機通常采用水—水或熱泵機組或水—氣熱泵機組。根據(jù)地下熱交換器的布置形式，主要分為垂直埋管、水平埋管和蛇行埋管三類。垂直埋管換熱器通常采用的是U型方式，按其埋管深度可分為淺層三種。

The ground source heat pump uses earth as heat source and heat sink, and the heat exchanger of the heat pump is buried in the ground to exchange heat and cold with the ground. The water source heat pump unit or water gas heat pump unit is usually used as the host of the ground source heat pump system. According to the arrangement of underground heat exchanger, mainly divided into vertical buried tube, horizontal buried pipes and pipe hunting three. The vertical buried tube heat exchanger usually adopts the U model, and can be divided into three shallow layers according to its buried pipe depth.

地源熱泵有開式和閉式兩種。開式系統(tǒng)：是直接利用水源進行熱量傳遞的熱泵系統(tǒng)。該系統(tǒng)需配備防砂堵，防結垢、水質凈化等裝置。閉式系統(tǒng)：是在深埋于地下的封閉塑料管內(nèi)，注入防凍液，通過換熱器與水或土壤交換能量的封閉系統(tǒng)。閉式系統(tǒng)不受地下水位、水質等因素影響，所以使用比較廣泛。

Ground source heat pump has two types of open and closed. Open system: a heat pump system that uses water for heat transfer directly. The system should be equipped with sand blocking, anti scaling, water purification and other devices. Closed system: a closed system for injecting antifreeze in a closed plastic pipe buried in the ground and exchanging energy with water or soil through a heat exchanger. Closed system is not affected by groundwater level, water quality and other factors, so it is widely used.

1、垂直埋管--深層土壤 垂直埋管可獲取地下深層土壤的熱量。垂直埋管通常安裝在地下50-150米深處，一組或多組管與熱泵機組相連，封閉的塑料管內(nèi)的防凍液將熱能傳送給熱泵，然后由熱泵轉化為建筑物所需的暖氣和熱水。

1, vertical buried pipe - deep soil vertical buried pipe can get the heat of the deep underground soil. The vertical tube is usually installed in the 50-150 meters underground, one or more groups of pipe and the heat pump unit is connected, antifreeze closed plastic pipe can transfer heat energy to the heat pump, then the pump into the building needed for heating and hot water.

2、水平埋管--大地表層 在地下2米深處水平放置塑料管，塑料管內(nèi)注滿防凍的液體，并與熱泵相連。水平埋管占地面積大，土方開挖量大，而且地下?lián)Q熱器受地表氣候變化的影響。

2, the horizontal buried pipe - the earth's surface in the depths of 2 meters underground, placed plastic pipes, plastic pipes filled with antifreeze liquid, and connected with the heat pump. The horizontal buried pipe occupies a large area and a large amount of earthwork excavation, and the underground heat exchanger is affected by the climate change of the ground surface.
