系统简介
地源热泵系统由能量采集系统、能量提升系统和未端能量释放系统（包括生活热水）三部分组成
GSHP System is composed of 3 parts:energy acquisition system,energy upgrading system and terminal energy release system(including hot water system).
地源热泵工作原理
Working Principle of GSHP System
能量采集系统
The energy acquisition system
能量采集系统将浅层土壤中的热能采集后送入换热器，与来自能量提升系统的循环水进行交换，使循环水不断地获得热量。
The energy acquisition system extracts heat energy from the shallow ground and delivers it into heat exchanger in which the energy makes heat exchange with the cycling water from the energy upgrade system.By doing so,the cycling water gets energy continuously.
能量提升系
The energy upgrading system
能量提升系统是由热泵机组的蒸发器、冷凝器、压缩机和膨胀阀等组成，按逆卡诺循环原理进行工作。蒸发顺中的液态制冷剂吸收循环水中的热量后汽化，被电动压缩机吸入后加压，然后进入冷凝器与未端循环水进行热交换，释放出热量，同是制冷剂冷凝成液体，经膨胀阀节流降压后再次进入蒸发器，反复循环。
The energy upgrading system has the following main parts: evaporator,condenser, compressor and expansion valve,etc.It works on reverse Carnot cycle principle:The liquid refrigerant will be vaporized when it absorbs the heat in the cycling water,and also be pressurized after getting into the electric compressor;and then it gets into the condenser making heat exchange with terminal circulating water and releases heat;then the refrigerant condenses into liquid and runs into evaporator after being decompressed by expansion valve.The process above is a complete cycle.
末端释放系统
The terminal release system
末端释放系统的循环水在冷凝器吸取热量后，输送到散热设备对建筑物进行供暖或经换热器对自来水进行加热，用作生活热水。
The cycling water wiich has extracted enough heat in the condenser of the terminal release system will be delivered into radiating devices,such as fan-coil etc,through the terminal circulating pump or heating the tap-water by the heat exchangers.And hten the heated tap-water will be delivered to where it is needed.
