摘　　要：内嵌管式围护结构是一种在墙体内预埋管道利用管道内流体循环在墙体内部实现冷热量转移的建筑结构。通过采用CFD数值模拟的方法,研究了无内嵌管道的常规墙体及内嵌管式墙体在夏热冬冷地区气候条件下的传热特性,结果表明了内嵌管式围护结构可以利用可再生能源大大的减少室外向室内的传热量及墙体蓄热量,降低了夏季/冬季时的室内冷/热负荷,并提高热舒适性。本文进一步研究了不同的水温对该围护结构传热的影响。A pipe-embedded building envelope,which is an external wall or roof with pipes embedded in it.This structure may utilize the circulating water in the pipe to transfer heat or coolth inside directly.The heat transfer of a pipe-embedded external wall and a conventional wall with the same configuration is numerically simulated under typical hot summer cool winter weather condition.The results show this pipe-embedded structure may reduce the cooling load in summer and heating load in winter by using renewable energy.This paper also presents the effects of the water temperature on the heat transfer of this structure.
