| 摘 要： | 设计了户式中央空调变风量控制系统，着重对末端控制器和中央控制器进行了研究。末端控制器采用PID算法调节房间送风量，控制室内温度。中央控制器实现两个控制功能：一方面控制系统新风量，另一方面是根据末端变风量调节（TRAV）思路，采集各房间温度和风量参数，对送风机进行模糊变频调速，控制系统总送风量。给出了控制系统硬件组成和软件实现，采用VB语言编制控制系统界面，界面简单友好，使用方便。

| Abstract: | The controlling system of household central air conditioning VAV system is designed; terminal controller and central controller are studied emphasizely. The single room temperature is controlled by the terminal controUer with PID algorithm. The central controller tins two controlling function, the one is controlling outside air volume, and the other is collecting the room temperature and airflow parameters by TRAV, controUing total airflow of the system, and fuzzy control is applied in the central controUer. In the end, the hardware organization and technique realization of software are both supplied. And VB language is used to compile control system interface, which is friendly and simple. |
