摘要
分析了集中空调系统水力失调的原因和解决措施,通过比较末端恒压差控制系统和应用电动可调式动态流量平衡阀的控制系统的控制原理以及变流量条件下的能耗高低,研究了这两个控制系统对管网中调节阀流量特性曲线的影响,具体分析了设备效率对系统性能的影响。
Examines the cause and solutions of hydraulic disorder of central air conditioning systems. According to the comparison of control principle and energy consumption under variable flow rate condition between the end constant pressure difference control system and the control system with electric adjustable dynamic balancing valve, studies the influence of the two control systems on the flow characteristic curve of the electric control valve, and analyses the influence of equipment efficiency on the performance of the system in detail.
