内蒙古中部地区土壤源热泵土壤温度恢复性测试与研究

Examination and Research on Ground Restoration of Ground-Source Heat Pumps in the Middle Area of Inner Mongolia

土壤源热泵在工作时,冬天从土壤中带走大量热量,夏天供冷时再把这部分热量补充回来,并带走冷量。部分研究指出,在冬天土壤源热泵从土壤中取走的热量在夏天并不能完全的补充回来,特别是针对热负荷远大于冷负荷的情况,有可能造成土壤温度逐年下降的趋势,使得土壤源热泵系统在运行一段时间以后效率下降,针对这种情况,重点研究了内蒙古中部地区呼和浩特市的内蒙古发展大厦土壤源热泵系统,此项目是国家第一批可再生能源建筑应用示范项目之一,也是首次在内蒙古地区使用土壤源热泵系统。通过对土壤温度为期2年的跟踪测试,分析土壤温度变化规律,并得到大量可供参考的数据,并进行归纳总结。

When the Ground-source heat pumps are working, they bring a lot of heat from ground in winter, which makes a supplement front supplying cold in summer. Some studies pointed out that the heat is taken from the ground by the Ground-source heat pumps in winter, however, it can not be fulfilled in summer, especially, under the condition that the heat load quarttity is much more than the cold load, it could lead to the temperature decline of ground year after year, furthermore, it may cause the efficieney decline of the Ground-source heat pumps after a while. In this case, the Ground-source heat pumps system in Hohhot city were discussed, the middle area of Inner Mongolia, This project is not only the first demonstration af the regenerated energy of our country, but also the first time use in Inner Mongolia. Through two years follow-tests of ground temperature, the variation of ground temperature was analyzed, a lot of consulted data were gotten, and the results were summarized.
