土壤源换热系统的有限元分析

Soil-Coupled Heat Pump System Simulation Analysis

讨论了竖直埋管在半无限大介质中的换热模型的计算,将虚拟热源法输入到有限元软件MARC中对换热器的温度场求解,并绘制了其相应的温度分布曲线图。针对等效管,单U型管,双U形管在温度影响半径方面进行横向比较,以确定等效管理论是否真正贴近实际,单U和双U的实用性效果。

Discuss the exchanging heat calculation of a pipe in half infinity medium, put dummy heat into Marc for temperature field result of exchanging heat vessel , and protract corresponding temperature distributing graph. In radius of temperature infection, put into compare among with equivalent pipe, single U pipe and double U pipe.. The aim is confirm equivalent pipe theory accord with the fact , and the effect of single U and double U.
