Hydraulic balance and control strategy of combination control system of electric adjustable dynamic balancing valve and terminal electric constant pressure valve

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.
