摘要
地下水源热泵采能技术作为一种浅层低温地热能的可持续开发方式,在我国推广应用已有近十年的时间。尽管推广时间不长,但发展速度非常之快,尤其是近3～5年。由于多方面的原因,我国部分地下水源热泵采能工程逐渐暴露出一些问题,需要给予足够的重视。本文介绍了地下水源热泵采能系统的运行模式及特点,简要地对国内外热泵采能技术的应用现状进行了综述,并对该项技术在我国推广应用过程中存在的一些问题,进行了一定的分析和讨论。
As a sustainable way of shallow and low-temperature geothermal energy mining, the technique of groundwater source heat pump system has been popularized in China for nearly ten years. Although the time of its application in China is not very long, the development of this kind of project is very fast, especially in recent 3-5 years. Due to multiple reasons in different aspects, there exist some problems in a considerable amount of energy mining systems using groundwater source heat pumps. These problems deserve high attention. In this paper, the groundwater production-injection modes and characteristics of this kind of energy abstraction systems are introduced and the state of arts of applications of the technique both in China and abroad is briefly generalized. Also, the existing and potential problems with this technique during its popularization and application in China are analyzed and discussed.
