竖直地埋管热响应试验与适宜性评价
摘要:以武汉某项目为例，分别采用恒热流法（R1孔：3 kW、6 kW）和恒温法（R2孔：进水温度30℃、35℃）对竖直双U型地埋管试验孔进行热响应试验。在介绍了项目地质情况、试验原理及试验设计的基础上，进行现场试验及结果分析与比较，并结合场地的水文地质条件以及岩土体可钻性，分析了竖直地埋管地源热泵系统在本地区的适应性，其结果可为地源热泵优化设计提供参考。
Abstract:Taking the ground source heat pump engineering project in Wuhan as an example,the thermal response tests were carried out of double U type vertical buried pipe using two methods for analysis and comparison,which were constant heatflux method and constant temperature method separately.There were two boreholes(R1、R2).R1 was tested by the constant heat-flux method,and the heat fluxes are 6 kW and 3 kW.R2 was tested by the constant temperature method,and the inlet temperature are 30℃ and 35℃.We discussed and analyzed the result of the tests based on introducing the geological condition of the project、the principle and design of the test.Combined with the hydro-geological conditions and drillability of rock and soil,we analyzed the suitability of vertical buried pipe ground-source heat pump system in this area and the study could provide useful references for the optimum design.
