地源热泵空调系统介绍

G.S.H.P Air Conditioning System Introduction

1.地源热泵空调系统的概念 G.S.H.P Air Conditioning System concept

地源热泵的广义理解是指以一切与大地有关的能量作为冷热源的热泵，包括以地下水为冷热源的水源热泵、以池塘、河流和湖泊等为冷热源的地源热泵等。这里所指的地源热泵是指狭义的理解，指利用大地作为热源，其通过地下换热器直接与大地土壤进行热交换，而不需要开采地下水的地源热泵。由于在地表以下一定深度的地层中在未受干扰的情况下常年保持恒定的温度，远高于冬季的室外温度，又低于夏季的室外温度，这样地源热泵可克服空气源热泵的技术障碍，大大提高效率。而且不需要开采地下水，这样可以消除水源热泵开采地下水所带来的不利影响。

The broad sense of GSHP refers to all the energy associated with the earth serves as a heat pump for cold and heat sources, including groundwater heat pump, cold and heat sources in ponds, rivers and lakes such as cold and heat source of ground source heat pump and ground source heat pump. Here refers to the narrow sense, refers to the use of the land as the heat source. Through the underground heat exchanger for heat exchange directly with the soil of the earth, without the need for GSHP exploitation of groundwater. Due to a certain depth below the surface of the formation constant keeps undisturbed conditions of temperature, far higher than the outdoor temperature in winter, and lower than the outdoor temperature in summer, the ground source heat pump can overcome the technique disorder of the air source heat pump, greatly improve the efficiency. And does not require the exploitation of groundwater, it can eliminate the adverse effects caused by the exploitation of groundwater source heat pump.

此外，冬季通过热泵把大地中的热量升高温度后对建筑供热，同时使大地中的温度降低，即蓄存了冷量，可供夏季使用；夏季通过热泵把建筑物中的热量传输给大地，对建筑物降温，同时在大地中蓄存热量以供冬季使用。这样在冬夏负荷相平衡的情况下，在地源热泵系统中的大地起到了蓄能器的作用，进一步提高了空调系统全年的能源利用效率。可以大大减少对化石燃料的消耗，减少对环境的污染，符合人类可持续发展的要求。

In addition, the earth in winter through the heat pump heat temperature of building heating, while the earth temperature decreases,i .e. the quantity of cold storage, can be used in summer; summer through the heat pump to transfer heat to the earth in the building, to the building cooling, while the heat is stored in the earth for the winter so in winter and summer load balanced conditions in ground source heat pump system in earth to the action of accumulator, to further improve the energy efficiency of air conditioning system. Can greatly reduce the consumption of fossil fuels, reduce the pollution of the environment, in accordance with the requirement of sustainable development.

2. 地源热泵空调系统的分类 (Classification of ground source heat pump air conditioning systems)

地源热泵系统室外地下换热环路(即地下热交换器)采用埋管(即埋置地下热交换器)的方 式来实现，埋管方式多种多样。目前国外普遍采用的有垂直埋管和水平埋管两种基本的配置形式 (如图所示)。

Ground source heat pump system for outdoor underground loop heat exchanger (i.e. underground heat exchanger) with buried pipe (buried underground heat exchanger) way, buried in a variety of ways. Widely used overseas vertical buried pipe and horizontal buried pipes two basic configurations (as shown).

垂直埋管是在地层中垂直钻孔，然后将地下热交换器以一定的方式置于孔中，并在孔中注入 填充材料的施工工艺。

水平埋管是在浅层土壤中挖沟渠，将换热管水平的埋置于沟渠中，并填埋的施工工艺。 地下热交换器型式和结构的选取应根据实际工程以及给定的建筑场地条件来确定。

The vertical buried pipe is drilled vertically in the stratum, then the underground heat exchanger is placed in the hole in a certain way, and the filling material is

injected into the hole Horizontal buried pipe is to dig trenches in shallow soil, and to bury the heat exchange pipe horizontally in the ditch and to bury it

Selection of type and structure of underground heat exchangers shall be based on actual engineering and given construction site conditions

3. 地源热泵空调系统的组成 (The composition of ground source heat pump air conditioning system)

地源热泵冷暖空调系统主要由 3 部分组成：室外地下换热环路系统；地源热泵机组；室内应 用换热系统。 Ground source heat pump air conditioning system is mainly composed of 3 parts: outdoor underground heat exchanger loop system; ground source heat pump unit; indoor application of heat
