摘要
地源热泵是利用可再生能源地热能的一种高效热泵系统,是未来发展的趋势。但在我国北方地区,大部分以热负荷为主,冬季地下埋管的取热量高于夏季的释热量,长期运行会破坏土壤温度场。介绍了太阳能-地源热泵复合系统,通过实验验证了太阳能辅助系统能够有效恢复土壤温度,提高系统性能系数,可以实现热泵长期稳定的运行。
The ground-source heat pump, a trend in the future, is a high efficiency system that uses the renewable geothermal. But in northern China, the heat load is the major way. In this, the heat that underground pipe absorbs in winter is more than the heat discharged by underground pipe in summer. After long-time running, the heat pump system will destroy the soil temperature field. This article describes a complex heat pump system of solar-ground source. And this article, through experiment, will prove that the solar assisted system can effectively restore soil temperature increase the coefficient of performance and achieve long-term stable operation of heat pump system.
