供热空调水系统的稳定性分析

Stability analysis of hydraulic networks in heating and air conditioning systems

为研究不同网络连接方式和系统调节方式对系统水力稳定性的影响 ,采用一个通用的水力稳定性定量分析指标对常用的异程系统、同程系统、分布式变频泵系统、混水系统以及环形网的稳定性作了分析比较 。

Adopts a general criterion evaluating the hydraulic stability of several types of networks including direct return, reverse return, distributed-pumps and loop networks in detail, which reveals the stability differences between these networks and the factors influencing the stability and reaches a few conclusions helpful to design and regulation in operation.
