中文摘要：

夏热冬冷地区,传统的地源热泵系统的长期运行会使得土壤温度逐年增高,造成系统效率逐年下降。为了解决这一问题,人们提出了复合式地源热泵系统的解决方案。介绍了某教学实验楼复合式地源热泵系统设计方法与原理,开展了冬、夏季对于机组和系统的性能测试,得到系统实际运行参数,并对其节能减排效益进行了测评。

英文摘要：

In the hot summer and cold winter zone, the long run of the traditional ground source heat pump system will cause the temperature of the soil increased year by year, which reduce the system efficiency. In order to solve this problem, people proposed hybrid ground source heat pump system. This paper introduced the design method and principle of hybrid ground-source heat pump system at the building of a college. Conduct performance testing of the unit and system in winter and summer to get the system running parameters and evaluate the benefits of energy conservation and emissions reduction.
