摘要
以河北承德地区一所医院的地源热泵空调系统为例,描述了该系统建筑信息和环境参数。为验证空调井换热的可持续性,利用Modflow软件建立单井循环换热的地能采集系统,进行地下水流场及温度场的数值模拟。通过分析不同时间段、不同条件下水流场及温度场的变化规律,找出实际工作中出现"冒水"及"热贯通"问题的根本原因,同时提出了合理建议,为地能采集井的设计工作提供了参考依据。
The building information and environmental parameters of the system are described,taking the ground source heat pump air-conditioning system of a hospital in Chengde,Hebei province as an example.In order to verify the sustainability of heat transfer in air conditioning wells,Modflow software was used to establish the ground energy acquisition system of single well circulation heat transfer,and carries out numerical simulation of underground water flow field and temperature field.By analyzing the change rules of water flow field and temperature field in different time periods and under different conditions,this paper finds out the root causes of the problems of“water bursting”and“thermal transfixion”in actual work,and proposes reasonable suggestions,which provides reference basis for the design of the ground energy acquisition well.
