摘要
本文通过TRNSYS搭建水平地埋管系统仿真平台,对水平U型地埋管换热器的换热性能进行研究。在郑州地铁车站实际环境下,分析不同埋深、不同间距等影响因素对水平U型管与土壤间换热性能的影响,研究表明埋设深度和敷设间距对埋管的换热性能有着重要的影响。
In this paper, TRNSYS is used to build a simulation platform for horizontal buried pipe system, and the heat transfer performance of horizontal u-type buried pipe heat exchanger is studied. Taking the subway station in Zhengzhou as the actual environment, different influence factors such as buried depth, different spacing on the level of U type tube and the influence of the heat transfer performance of the soil was analyzed. The studies have shown that buried depth and laying distance heat-exchange performance has an important influence.
