上海地区地下水源热泵技术应用实例研究

摘要

A groundwater heat pump is a new method of developing and utilizing shal ow geothermal energy. It has the advantages of high efifciency, energy savings, and environmental beneifts. There is a wide range of applicability, and its market is broad. As there is an imbalance between the supply and demand of energy, it is very necessary to develop and utilize the ground water heat pump technology in Shanghai. In this study, research on the application of this technology in the Shanghai area further veriifes the optimal design (such as the use of a 100%closed recharge, reasonable wel spacing, and other measures), ensures that the ground water heat pump system has a smal and control able effect on the geological environment, and shows that the technology has signiifcant economic and environmental beneifts.%地下水源热泵是一种新兴的浅层地热能开发利用方式，可将不能被直接利用的低品位地热能提升为可利用的能源，并具有高效节能、环境效益显著、适用范围较广、市场前景广阔等优点，对于能源供需矛盾突出的上海，开发利用地下水源热泵技术十分必要。本文通过上海地区地下水源热泵技术应用实例研究，进一步验证通过优化设计（如采用全封闭100%回灌、合理的井间距等措施），可使地下水源热泵系统对地质环境影响微小、可控，且经济环境效益显著。
