摘要
地源热泵技术是利用地热能的重要方式之一,地热能可代替常规能源用于建筑物的制冷和供热,在建筑节能减排中起到积极作用.地埋管是地源热泵系统的重要部件,目前关于地埋管技术研究主要集中在浅层(40～200 m)和中深层(1 500～3 000 m)地埋管,浅层和中深层地埋管技术发展为中浅层(200～600 m)地埋管技术的研究提供参考.中浅层地埋管的单井换热量数倍于浅层地埋管,并且可以承担更大的冷热负荷不平衡率,拓宽了地源热泵的应用范围.文中总结了浅层、中浅层和中深层地埋管的基本原理、理论研究和技术应用,对未来技术发展提出展望.
Abstract
Ground source heat pump technology is one of the important ways to utilize geothermal energy,which can replace conventional energy for cooling and heating in buildings,playing an active role in energy saving and emission reduction in construction.Ground buried pipes are an important component of the ground source heat pump system.Current research on ground buried pipe technology mainly focuses on shallow(40～200 m)and medium-deep(1 500～3 000 m)ground buried pipes.The development of shallow and medium-deep ground buried pipe technology provides a reference for the research of medium-shallow(200～600 m)ground buried pipe technology.The heat exchange capacity of a single well of medium-shallow ground buried pipes is several times that of shallow ground buried pipes,and they can bear a greater imbalance rate of cold and heat load,which expands the application range of ground source heat pumps.The text summarizes the basic principles,theoretical research,and technical applications of shallow,medium-shallow,and medium-deep buried pipes,and looks forward to the future development of the technology.
