埋管式地源热泵系统也称地下耦合热泵系统或土壤热交换器地源热泵，包括一个土壤耦合地热交换器。它或是水平安装在地沟中，或是以U形管状垂直安装在竖井之中。通过中间介质作为热载体，使中间介质在土壤耦合地热交换器的封闭环路中循环流动，从而实现与大地土壤进行热交换的目的。

The buried pipe ground source heat pump system is also known as the underground coupled heat pump system or the soil heat exchanger ground source heat pump, including a soil coupled geothermal exchanger. It is either installed horizontally in a ditch or vertically installed in a shaft in a U shaped tube. The intermediate medium is used as a heat carrier to make the intermediate medium circulate in the closed loop of the soil coupled geothermal exchanger, so as to achieve the purpose of heat exchange with the earth's soil.

1、水平埋管地源热泵系统。

1. Horizontal buried pipe ground source heat pump system.

比较简单的方式是当室内负荷比较小，土壤换热器长度比较短，可以把与单回路管子随开挖土方施工直接埋入地下。

A relatively simple way is that when the indoor load is relatively small, the length of the soil heat exchanger is relatively short, and the single loop pipe can be directly buried into the ground with the excavation of earthwork.

2、地下水热泵系统

2. Ground water heat pump system

也就是通常所说的深井回灌式水源热泵系统。通过建造抽水井群将地下水抽出，通过二次换热或直接送至水源热泵机组，经提取热量或释放热量后，由回灌井群灌回地下。无论是深井水，还是地下热水都是热泵的良好的低位热源。地下水位于较深的地方，由于地层的隔热作用，其温度随季节气温的波动很小，特别是深井水的水温常年基本不变，对热泵的运行十分有利。

It is usually called the deep well recharge water source heat pump system. Through the construction of pumping wells group, the groundwater is pumped out, through two heat exchange or directly sent to the water source heat pump unit. After extracting heat or releasing heat, it is pumped back to the ground by the well group. Both deep and underground water are good low-level heat sources for heat pumps. Groundwater is located in a deeper area. Due to the heat insulation function of the stratum, its temperature fluctuates very little with the seasonal temperature. Especially, the water temperature of the deep well is basically unchanged all the year round, which is very favorable for the operation of the heat pump.
