Study of Intelligent Control System in Air-conditioning System Experiment Installation

According to the application situation of central air-conditioning system in China, an experiment installation of intelligent air-conditioning system is designed which is based on BAS (building automation system) of EBI (enterprise buildings integrator) of automated logic corporation. This study is to analyze the composition and characteristics of this installation. The hardware and software are presented. The software includes the EBI and CARE (computer aided regulation engineering) of the corresponding upper and lower computer. At last the control strategy of the installation is discussed, which includes the cascade control and hybrid fuzzy-PID control algorithms. Especially the supply air temperature and air-conditioning room air temperature is controlled coordinately by adjusting the air system and water system. By flexibly configuring the software and hardware of the system, this installation can fulfil various research tasks as air-conditioning system characteristics, indoor airflow and control strategy, and the economy running mode of air-conditioning system
