应用水力失调度校核采暖房间温度变化的理论分析

The Theory Analysis for the Hydraulic Im-balance degreeto Check the Change of Hea-ting Room Temperature

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。本文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 achoeve full banlance due to the liomit of various conditions and the changes of conditions in motion, which causes the difference between the real water flow of the calcuilated section and the stipulated water flow, and further results in a big deviation between the designed temperature and the actual temperature in the herting room.this article deduees in theory the influerce of water flow changes on the temperature of the heating room and the range of the permitted fluctuation of the hydraulic imbalance degree of pipeline.
