Central Air-Conditioning Terminal Intelligent Control System

According to the current situation of the traditional central air conditioning system and the technical requirements of the partner, this paper designs and develops a central air conditioning intelligent control system which takes WQ-series PLC as its master controller. Designing three operating modes for the central air conditioning terminal control system and making a detail introduction. This system is based on the size of the absolute deviation between indoor actual temperature and setting temperature, using self-adaptive PID control, environment temperature compensation control, day and night time automatic variable compensation coefficient control and other intelligent control to achieve the following and decoupling control of the flow and temperature and the purpose of energy-saving, creating a good economic and social benefit.
