地源热泵技术的研究与应用现状

Research and Application Status of Ground Source Heat Pump Technology

在科学技术飞速发展的影响下,地源热泵技术的整体水平也得到了良好的提升,其借助于地下土壤和地下水的温度持续维持稳定的性质,运用少量的电能做功,将地下土壤或者是地下水热能转变为社会活动需要的能量,这也是将低品位能源转变为高品位能量的一种有效方式。文章通过对地源热泵的形式及原理进行分析,分别对垂直式、水平式、地下水式三种地源热泵进行了论述,指出了地下冷热平衡研究、热积累问题、设计中涉及问题、工程管材方面的因素、井水回灌问题等方面的问题并给出建议,从而更好地认识地源热泵技术,为我国地源热泵技术应用提供参考与借鉴。

Under the influence of the rapid development of science and technology,the overall level of ground source heat pump technology has also been well improved.With the help of the nature that the temperature of underground soil and groundwater continues to maintain a stable state,it uses a small amount of electric energy to do work to transform the heat energy of underground soil or groundwater into the energy required by social activities,This is also an effective way to transform low-grade energy into high-grade energy.Based on the analysis of the form and principle of ground source heat pump,this paper discusses three types of ground source heat pump:vertical,horizontal and underground,finds out the problems of underground heat and cold balance research,heat accumulation,problems involved in design,factors of engineering pipe,well water recharge and so on,and gives suggestions,so as to better understand the technology of ground source heat pump,It can provide reference for the application of ground source heat pump technology in China.
