武汉某工程水源热泵系统关键技术的设计与应用
Design and application of key technology to water-source heat pump system for a projeet in Wuhan
摘要：
为利用武汉地区丰富的地热资源和夏热冬冷的气候条件，武汉某项目采用了水源热泵集中空调系统。介绍了工程概况与抽水回灌试验。运用Modflow软件对井群系统进行了建模分析，结合抽水回灌试验归纳总结了地下水渗流场规律。根据模拟结果和试验中发现的问题，改进后采用两管式抽灌两用井和基于三维有限差分模拟试验的井群定位布置施工方法，形成了一套科学合理、便于施工和管理的地下水取用和回灌工法。该工法在武汉某项目中成功实施，近几年运行稳定，运行费用大大降低。
Abstract：
Applies a water-source heat pump central air conditioning system to a project in Wuhan, due to the rich geothermal resource and the hot summer and cold winter climatic condition in Wuhan. Presents the profile and pumping and recharging test of the project. Establishes and analyses a model of the well group system by Modflow software. In view of the pumping and recharging test, summarizes the law of ground-water seepage field. According to the problems in the simulation results and experiments, adopts a two-pipe pumping and recharging well and arranges the well group based on three dimensional finite difference simulation test method, and forms a set of scientific and reasonable method for ground-water pumping and recharging. The method has been successfully implemented in a project in Wuhan, with stable operating in recent years and low operating cost.
