典型气候带地埋管地源热泵运行对地温场的影响分析

Influence of Geothermal Field by Operation of Ground Source Heat Pump with Underground Pipe in Typical Climate Zone

我国的浅层地温能开发利用以寒冷地区和夏热冬冷地区应用最为广泛,利用方式以地埋管地源热泵系统为主。其中寒冷地区北京、天津、河北等省市发展规模较大,夏热冬冷地区江苏和浙江两地发展规模较大。本文选取寒冷地区和夏热冬冷地区规模较大、具有代表性的地埋管地源热泵工程开展了地温场的监测,分析了地温场的监测数据。结果表明,受气候带的影响建筑物的供暖和制冷情况会有所差异,但其所使用的地源热泵系统运行对地温场的影响非常有限,不会因气候带的差异而有所差别。

Based on the present situation of shallow geothermal energy development and utilization in China, this paper studies the shallow geothermal energy development and utilization, which is most widely used in cold areas, or in the areas with hot summer and cold winter in China. The main mode of utilization is ground source heat pump system with buried pipes. In the cold areas, the geothermal energy are mainly utilized in Beijing, Tianjin and Hebei, and in the areas with hot summer and cold winter, the geothermal energy are mainly utilized in in Jiangsu and Zhejiang. Based on the division of climate zones, the largescale and representative ground source heat pump projects in above two climatic zones are selected to monitor the geothermal field, which monitoring data are analyzed. The results show that the buildings’ heating and cooling will be greatly affected by climate zones. But the influence of ground source heat pump system on geothermal field is very limited and will be no difference between climatic zones.
