地埋管换热器长期运行传热模拟分析

Simulation Analysis of Long-Term Operation Heat Transfer of Ground Heat Exchanger

利用浅层地热能与热泵技术相结合为建筑物供暖、制冷的地源热泵技术,已经成为建筑领域常用的高效节能技术,得到了越来越多的重视和应用,发展迅速。而且经过长时间的实际应用,该项技术不断得到了进一步的完善。目前,政府正在大力提倡节能减排技术,并且已经对公共建筑出台相应的节能标准,相关鼓励、扶植该项技术发展的政策法规正在制定当中。结合某项目勘察测试报告,验证建立的模型,对长期运行的单U32地埋管换热器进行了模拟,对模拟结果进行分析,为该项目后续的运行提出参考建议。

The use of shallow geothermal energy and heat pump technology combined for building heating,cooling ground source heat pump technology,has become a common energy-saving technologies in the construction field.People pay more and more attention to it,and its development is rapid.After a long period of application,the technology has been further improved.The Government advocates the technology of energy-saving emission reduction,and introduces the corresponding energy-saving standards.Based on the investigation report of a certain project,this paper validates the established model and simulates the long-term operation of a single U-type32,analyzes the simulation results,and makes suggestions for the follow-up operation of the project.
