应用水力失调度校核采暖房间温度变化的理论分析

Theoretical analysis for the hydraulic imbalance degree in the check of heating room temperature change

在热水供暖系统水力计算时，由于受各种条件的限制，并联管路的压力损失不能达到完全平衡，以及在运行中条件的变化，使得计算管段的实际水流量与规定流量不同，从而导致供暖房间的温度与设计温度偏差较大。为此从理论上导出了水流量变化对供暖房间温度的影响以及管路水力失调度允许波动的取值范围。

In the hydraulic calculation of hot water heating system,the pressure loss of the parallel pipeline cannot achieve full balance due to the limit of various conditions and the changes of conditions in motion,which causes the difference between the real water flow of the calculated section and the stipulated water flow,and further results in a big deviation between the designed temperature and actual temperature in the heating room.This article deduces in theory the influence of water flow changes on the temperature heating room and range of the permitted fluctuation of the hydraulic imbalance degree of pipeline.
