摘要 本文提供了测量垂直埋管土壤热交换器换热量相对精确数据的实验过程,并对高密度聚乙烯单U型管、高密度聚乙烯+不锈钢单U型管、高密度聚乙烯双U型管三种管型布置进行了实验对比研究。对在北京南部自主建立的地源热泵实验系统的垂直土壤热交换器的换热量、土壤热交换器的进出口水温、三种管型布置供水温度的下降速率进行了实验和分析,相信本文结果对于地源热泵理论研究及工程设计具有一定的参考价值。 The paper describes the experiment process on which we have carried in order to obtain comparatively accurate data of the heat exchange capacity, and carry out comparative research of the three installation types which are Single high density polyethylene U-type pipe, Single high density polyethylene & stainless steel U-type pipe, and double high density polyethylene U-type pipe. We undertake experiment and analysis of heat exchange capacity of ground heat exchangers, inlet & outlet water temperature of ground heat exchangers, and water supply temperature drop speed of the three pipe structures. We believe that conclusions of the paper have certain reference values for theoretical research and project design of ground source heat pimp.
