摘　　要：利用Fluent软件建立混合式地源热泵系统模型,对武汉地区办公建筑的混合式地源热泵系统进行数值模拟,比较连续运行和2种间歇运行工况下的系统能耗,以期找到既减少能耗又有利于土壤温度场恢复的间歇运行工况。Due to the low thermal diffusivity and heat transfer of soil, continuous operation of ground source heat pump will increase soil temperature. Intermittent operation can restore soil temperature and raise efficiency of heat pump. In this paper, a HGSHP system was built by Fluent and then numerical modeling the HGSHP of an office building in Wuhan. In order to find an intermittent operation which can not only save energy but also be conducive to restore the soil temperature, tbe energy consumptions were compared between continuous operation and two intermittent operations.
