摘要
文中介绍了垂直U型埋地换热器地源热泵系统的现场换热试验方法,并结合某地源热泵示范工程,通过垂直竖井单U型管埋地换热器的现场换热试验,研究了地下换热器的进出水温差和平均温度,冬夏季地源热泵的吸(排)热量、制热(冷)量及循环性能,为地源热泵的工程设计提供了参考。
The paper introduces the experimental way of heat transfer performance of the GSHP system with vertical underground U-pipe heat exchangers.Combining with a ground source heat pump demonstration project,based on the heat exchanging experiment of the GSHP system with U-pipes,it studies the temperature difference of in-let and out-let water,and the average water temperature in the pipe,the heat absorption（excluding） quantity,heating（refrigerating）quantity and cycle performance of the GSHP in winter and summer,and provides the reference for engineering design of the GSHP system.
