摘要
介绍了一种主要应用于实验柜的排风控制系统的设计。此装置包括微控制单元、执行器单元、传感器输入单元、显示单元和操作单元5大部分,使通风柜具有智能化、变风量控制功能。通风量的大小完全由电脑控制,操作简单,保证排出有害气体的效果始终处于最佳状态,不仅能精确地控制排风量,还可以降低能耗、减小噪声,甚至无噪声工作(有多种工作状态)。该装置可有效地应用于核医学科和普通化学实验室。
The design of an air exhaust control system mainly used in lab fume hood is introduced.This device is composed of MCU,final control unit,sensor input unit,display unit and operating unit.All of this makes the fume hood intelligent and to achieve VAV control function.The volume of ventilation is totally controlled by a computer.It is easy to operate and can guarantee the effect of discharge of harmful gas at the optimal status.It can control the air exhaust rate precisely,and reduce the power consumption and noise.The device can effectively be used in the nuclear medicine and common chemical labs.
