摘　　要：通过土壤源热泵系统的运行性能分析,认为采用系统热回收的方案,夏季既能减少向地下排放热,又能提高冷水机组的工作效能;春、秋季节地下换热器的换区运行,能平衡各井区被吸收的热量,还能使各井区得到较长间隙的恢复;冬季因系统热回收运行,地下换热器出水大于16℃,使空调机组与热水机组的工作效率高且稳定。Through the operation of ground source heat pump system performance analysis, that a ＂system of heat recovery＂program, the summer will reduce emissions of heat to the ground, but also improve work efficiency chillers; Spring and autumn, the ground heat exchanger for district operation, can well balanced all the heat was absorbed, but also to be a long gap of the well field restoration; Winter because of heat recovery system, running water underground heat exchanger is greater than 16 ℃, the air conditioning unit and hot water unit of work high efficiency and stability.
