效率高、环保效能好的供热制冷装置——地源热泵的开发与利用

Development of Heating and Cooling Equipment with Saving Energy & Environment Protection——Ground Source Heat Pump System

地下浅层地能资源 (包括土壤、地下水、地表水和人类的生产生活低位能量等 )的非开采利用 ,可以通过热泵装置实现供热和制冷的双重作用。地源替代常规空气源 ,充分利用了地温逆变性 (冬暖夏凉 )和常年温变小以及蓄能的特点 ,实现了能量的再利用和良好的环保效能。使在北方冬季应用热泵供暖系统成为现实 ,并可实现供热制冷系统一体化。本文概述了国内外该领域的发展状况和该技术的可行性。

Ground source heat pump(GSHP) system can provide heating and cooling with higher efficiency and cleaner environment,by means of the un exploitative utilization of shallow ground energy source(soil,groundwater,surfacewater,and surplus energy produced by industry and human living).Ground energy source substituting conventional energy source(air source)in the heat pump,has a reverse temperature change state(warm in winter and cold in summer),a small temperature variation,and big storage of energy.It can attain regeneration of energy and GSHP systems realize green,clean environment.Furthermore,the GSHP systems can be used in the north (cold climate),and can provide heating and cooling with the same system and equipment.This paper summarizes the development of GSHP system in the world and the feasibility of its utilization in the northern districts of China.
