介绍了淮安城市规划区水文地质条件、岩土体结构、地温场特征以及岩土层的热物理参数,结合地下水地源热泵系统和垂直地埋管地源热泵系统的应用特点,对两种类型的地源热泵系统在淮安规划区应用的可行性进行了分析。结果表明城市规划区面积约97.5%的区域不适宜应用地下水地源热泵系统,仅在规划区西北角小范围内较适宜应用;而垂直地埋管地源热泵系统可适宜在规划区内大面积推广应用,地埋管深度一般100m左右;最后对规划区两种类型的地源热泵系统应用过程中需要注意的几个问题进行了阐述,为淮安城市规划区地源热泵系统规划与试点工作提供了科学依据。
This paper introduces the hydrogeological conditions, the geotechnical structure, the geothermal field characteristics and the thermal physical parameters of rock and soil layers in the urban planning area of Huai’an City. Combined with the application characteristics of the ground source heat pump system and the vertical ground source heat pump system, The feasibility of applying ground source heat pump system in Huai’an planning area was analyzed. The results show that the urban planning area of about 97.5% of the area is not suitable for groundwater source heat pump system, only in the northwest corner of the planning area is more suitable for small areas; and vertical buried ground source heat pump system can be suitable for planning a large area The depth of buried pipe is about 100m. Finally, several problems needing attention during the application of the two types of ground-source heat pump system are elaborated, which provide the planning and pilot work of ground source heat pump system in Huai’an urban planning area The scientific basis.
