| 摘 要： | 针对供暖工程中并联环路阻力损失计算与流体力学中的并联环路计算的不同,指出流体力学中的并联环路不存在自然作用压力差,而供暖系统中的并联环路有自然作用压力差的作用,并导出了供暖工程中并联环路的阻力损失计算式,从而解释了当供暖系统中的并联环路阻力损失的差值与自然作用压力的差值不同时出现垂直失调、导致室温的波动,并通过实例进行了分析计算。

| Abstract: | The paper analyses the difference between resistances loss calculation of parallel circuit in heating engineering and hydromechanics.Gravity pressure has no influence on the parallel circuit in hydromechanics,but has influence on heating engineering.It establishes mathematical models for "resistance loss calculation of parallel circuit in heating" engineering.Room temperature becomes imbalanced vertically when difference of resistance loss is not equal to gravity pressure difference in parallel circuit in heating engineering,which is analyzed through the example. |
