基于PID调节的中央空调温湿度控制系统

Control System of Central Air-conditioning Temperature and Humidity Based on PID Regulator

采用三菱FX2n—48MR型PLC替代以往的专用控制器,作为中央空调控制系统核心,具有良好的灵活性和可靠性;并利用三菱PLC的PID功能指令对室内温、湿度进行调节,提高控制精度,具有良好的应用前景。

This design uses a Mitsubishi FX2n-48MR-based alternative to the past, a dedicated PLC controller as the core of central air-conditioning control system has good flexibility and reliabihty; and using PID function instruction on the indoor temperature and humidity to adjust and improve the control accuracy, has good application prospects.
