摘要
本文综合国内外地下水源热泵研究现状,通过对北京地区地下水源热泵利用现状调查分析,重点分析了地下水水源热泵利用过程中存在的不能完全回灌、回灌水温差过大、水井布设不合理等问题。结合北京平原区第四系水文地质条件,分析了不同含水层结构下如何合理布设地下水源热泵系统的用水井,尽量避免水源热泵系统的使用对地下水的影响。
The present paper, based on an analysis of the present situation of groundwater heat pumps (GWHP) use in Beijing, focuses on a discussion of the following problems: groundwater cannot be completely reinjected into the aquifer; the temperature difference between the pumping well and the injection well is too great; and the distribution of water wells is not scientific and rational. Taking considerations of the Quaternary hydrogeological conditions in Beijing, the paper discusses how to place the wells rationally under different aquifer structures and to avoid impacts of the heat pumps on groundwater quality.
