江苏淮安浅层地温能资源开发利用条件分析

Study on development conditions of shallow geothermal resource in Huaian of Jiangsu

通过对淮安市太阳能照射条件、气候条件、地形地貌等自然因素及构造、岩土体热物理特征、水文地质条件等地质因素的介绍,阐述了浅层地温能赋存条件、分布特点;结合不同地热泵系统应用条件,初步评价其适宜性。淮安市浅层地温能资源赋存条件优越,开发潜力巨大,地源热泵系统应用前景广阔,但在开发利用浅层地热能资源时,从保护地质环境、预防地质灾害的角度出发,不适宜采用地下水热泵系统,推荐选用垂直地埋热泵系统。

Based on the analyses of solar irradiation conditions,climate conditions,topography,tectonics,thermal physics of rocks and soils and hydrogeological conditions in Huaian City,the author depicted the occurrence conditions and distribution characteristics of shallow geothermal heat,evaluated its suitability in combination with the application conditions for different geothermal pumping system. Geothermal heat pump was of broad application prospect,but groundwater heat pumping system was not suggested to adopt for the sake of environment protection and vertical ground heat pump system was recommended to use in Huaian City.
