摘　　要：计算和分析了稳态和非稳态2种状态下管道内流体对管道热损失的影响以及非稳态的热水供给回水系统管道中的热量损失,得出依实际需要通过减少系统运行时间可减少管路中热损失的结论。This paper calculates and analyses the influence of pipeline heat loss which caused by fluid inside the tubes under steady-state and unsteady-state, and heat loss of backwater system supplied by hot water inside the tubes under unsteadystate. At last the author draws the conclusion that we can reduce heat loss inside the tubes by reducing the system operating time.

关 键 词：太阳能热水系统 回水系统 稳态 非稳态 管道热损 循环时间
