垂直单管跨越式系统水力工况分析

Hydraulic Condition Analysis of Vertical Single-pipe Cross-over System

分别从采暖热力入口定压差和定流量两种情况下,探讨了公共建筑中常用的垂直单管跨越式采暖系统的水力工况。分析了用户自行调节过程中系统的水力工况稳定性。总结出系统入口定压差控制方式的垂直单管跨越式系统,具有近似定流量的良好特点,而且用户调节时相互影响较小,是理想的公共建筑采暖系统形式。

The common hydraulic conditions of vertical single-pipe cross-over system were discussed in public buildings from constant differential pressure and constant flow of heating supply entrance.The hydraulic condition stability in the system was analyzed in the course of control by heat consumer.It was summarized that the vertical single-pipe cross-over system for the pressure differential control mode of the system entrance was the perfect attended mode of heating supply entrance, which had better properties of approximately constant flow, and in which the mutual effects were smaller when controlled by consumers.
