摘　　要： 针对一个3715 m2地源热泵系统,进行了系统运行特性的长期测试实验。结果表明,长期运行条件下,热泵机组平均COP分别为3.55(冬季)和2.80(夏季),冬季工况和夏季工况的系统COP分别呈递增和递减趋势,且变化规律可表述为指数形式。与冬季工况相比,夏季工况的系统COP波动较大,而且在初始阶段存在一个峰值。 Aiming at a 3715m^2 ground source heat pump system, the long-term experiments for its operational performances are conducted. The results show that during the long-term operation, the average COP of heat pump units is 3.55 in winter and 2.80 in summer. The COP of GSHP system tends to be increasing in winter and decreasing in summer. The fluctuation rule can be descr/bed as an exponential function. The GOP of GSHP system fluctuates greater in summer than in winter, and there is a peak value in the initial operation.
