上海地区地下水源热泵系统适用性研究

Research on applicability of groundwater source heat pump system in Shanghai

浅层地热能作为在当前技术经济条件下具备开发利用价值的特殊矿产资源,得到了较好的推广和应用,特别是地埋管地源热泵系统的应用发展较快。而对于应用效率更高,占用地下空间较少,以温度较为稳定的地下水为媒介,通过热泵技术进行热交换的地下水源热泵系统研究较少。本文旨在综合分析与评价资源条件,通过应用案例重点对系统运行可能造成地质环境变化的影响因素进行监测和研究,分析地下水源热泵系统应用的适用性,为上海地下水源热泵系统的推广应用提供决策依据。

Shallow geothermal energy has been greatly developed and publicized as an affordable mineral resource that is worthy to research under today’s economic environment and technological conditions.The application of ground source heat pump system using buried pipelines is advancing especially rapidly.However,the underground water-source based heat pump system has attracted much less research and attention.This system employs underground water,which has a relatively stable temperature,and heat pump technology to accomplish ground heat exchange;it not only is more efficient but also requires less space.This paper tries to achieve a comprehensive analysis and an evaluation of resource condition of the underground water-source based heat pump system.The potential factors caused by such system that may create geological impact on the environment are carefully monitored and studied.The goal of the paper is to analyze the applicability of this system in order to provide advice for the urban plan to further develop the underground water-source based heat pump system.
