前馈控制与点阵在空调节能中的应用

Application of Feedforward Compensation and Dot Matrix in Air Conditioning Energy Conservation

通过使用压电陶瓷制成点阵状的传感器,感应进出空调房间的人流,判别进出人员的性别、身高、体重和行进方向,从而对中央空调系统做出较精确的前馈控制,达到减少空调系统的瞬时冷负荷及新风量,在满足人体热舒适性要求的同时减少空调系统的能耗。

Piezoelectric ceramic can be used to make a dot matrix sensor which counts the number of people and analyzes their sex,height,weight and the walk direction approximately and to control central air-conditioning system relatively precise.This system can be used to reduce fresh air volume and instantaneous cooling load,so as to reduce air conditioning cooling energy consumption under the condition of people comfort.
