摘 要:
地下埋管内的水温主要与埋管换热器的长度、地下土壤温度、土壤的热物性及系统运行模式等因素有关。系统最佳运行模式对于地下温度场的恢复、系统运行优化以及减少埋管换热器的造价都有重要意义。文章通过人为控制机组的运行模式，探求连续运行及间歇运行模式下埋管换热器内水温变化规律，以期找到地下换热系统运行优化的最佳手段。[著者文摘]

Abstract:
The water temperature of the underground heat exchanger is mainly influenced by the length of the underground heat exchanger,the soil temperature ,the soil thermal characteristics and the system operation mode and so on.It is of significance for the ground temperature property ,the system operation and for loosening the cost of the underground heat exchanger if we can find out the best operation mode. Aimed at this purpose, by the operation mode of artificial control, investigate the changes of the water temperature of the underground heat exchanger at continuously operation mode and periodical operation mode, try to find out the best operation mode of the underground heat exchange system.[著者文摘]
