地下水源热泵系统是一种经济节能环保型中央空调系统,热源井作为系统取热或放热的源或汇是系统成败的关键。本文提出了热源井设计的方法及井结构、井数、井间距、井群布置对系统的影响,分析了热源井施工工艺流程中填砾、封井、洗井、潜水泵选择等过程的重要性,提出了地下水源热泵系统热源井设计、施工的关键问题及相互作用。最后以宝汉高速公路沿线某站点为实例,验证该研究在工程项目的可行性。
Groundwater source heat pump system is an economical, energy-saving and environment-friendly central air-conditioning system. The source or sink of the heat source well as a system to remove or dissipate heat is the key to the success or failure of the system. In this paper, the design method of heat source well and the influence of well structure, well number, well spacing and well group arrangement on the system are analyzed. The importance of filling gravel, well closure, well washing and submersible pump selection in the heat source well construction process is analyzed The key problems and interaction of design and construction of the heat source well of groundwater source heat pump system are put forward. Finally, a site along Bao - Han Freeway is taken as an example to verify the feasibility of this research in the project.
