摘　　要：地源热泵空调系统设计最主要的依据是地下土壤和岩石的换热能力,本文采用"恒流法"对浙北地区某地源热泵系统土壤的换热性能进行了测试。结果显示73m孔与43m孔热物性基本相同,导热系数大约为1.66W/(mK),钻孔内热阻为0.0339(mK)/W,容积比热(ρsCs)为2649 kJ/(m3K),反映土壤换热性能较好,能充分发挥地埋管换热系统的优势。The main basis of designing the ground source heat pump air conditioning system is the heat transfer ability of underground soil and rock. In this paper, tests were carried out on the soil＇s heat transfer performance using Constant-current method, deriving from a GHSP project in the north of Zhejiang Province. The results show that 73-meter hole in diameter has almost the same thermal performance as 43-meter hole＇s, coefficient of thermal conductivity is about1.66 W/ （mK）, drilling hole＇ s internal thermal resistance is 0.0339 （mK）/W, and volumetric heat is 2649 k J/ （m3K）, indicating the good heat transfer performance of the target soil. In this way, the advantage of buried heat exchanging system can be fully developed.
