摘要
分析了异程系统干管压差控制、异程系统末端压差控制、同程系统干管压差控制、同程系统末端压差控制、环形管网干管压差控制和环形管网末端压差控制对变流量空调水系统水力稳定性的影响。计算结果表明,同程系统、环形管网末端压差控制具有最好的水力稳定性。
Analyses the effect of different pressure difference control methods on hydraulic stability of variable flow air conditioning water systems, including main pipe pressure difference control and end pressure difference control of direct return system, reversed return system and loop pipe network. The results indicate that end pressure difference control of reversed return system and loop pipe network makes the most desirable hydraulic stability.
