Abstract

The controlled object in constant-temperature and constant-humidity air-conditioning system has characteristic such as multi-disturbance, multi-work-condition and couple of temperature and humidity, etc. This paper designs a measurement and control system. The annual work condition and regulation method is analyzed, and the hardware and software are described. The control system of field controller is programming in configuration software, and the control strategy, on-off logic and time program are designed. The experiment results show that the designed control system is valid and reliable to satisfy the requirement of the air-conditioning system.
