The working principle of ventilation counter wind speed control system/通风柜面风速控制系统工作原理

1. Surface wind speed control system continuously monitor s the Bctual exhBust Bir wolume of the fume cabinetCalculate the average wind speed of the open area according to the height of the window, When the exhaust pipe pressure changes the window height changes. the system responses within a second adjust the openlng of the air valve to keep the average surfece wind speed of the window open surface stable.

面风速控制系统持续地监测通风柜实际排风量,根据视窗高度计算出视窗开口面积的早均面凤遣,当排凤管道压力变化或视窗高度发生变化时,系统在心1S的时间做出反应。及时调整风阀开度保持视窗开口面积的早均面凤遭稳定。

2. Under dfferent experimental cond, itions, we can set diferent parameters on the panel.

不同实验状况时,可在面板上设置不同的参数。

3. The system controls surtace wind speed at a set speed (0. 5m/s) through intrared detector when there Is an operator in tront of the ventilation cabinet the system automatically swiches to another value(e.g.0.3m's)to save costs when there is no operator in front of the fume cabinet.

系统通过红外线监测器当通风柜前有操作人员工作时而风唐控制在某一设定值(0.5m/s),当通风柜前无人操作时,系统自动转换到另-设定值(如0.3m/s)以节省运行费用。

4. When venfilation cupboard door was off, the air valve maintains the minimum of the venilation cabinet exhaust air 1500MM,the ventilation cabinet 300CMH.

当通风柜门关闭后,风量阀要维持通风柜的最小排风量,1500MM通风柜为300CMH。

5. Due to the fault surtace wind speed is high low, there will be sound-light alarms.

由于故障面风速过高或过低时有声光报警。

6. When temperatures of ventiation cabinet are high, there will be sound-ligh alarms.

通风柜温度过高时有声光报警。

7. When the position of the ventlation cabinet is 100 high, there will be sound -light alarms ,

通风柜门位过高时有声音报警。

B、When there is an exception, open the emergency discharge mode control the sy8tem will open all the air valves.The maximum air volume of the ventilation cabinets is free the control of the wind speed value.

当出现异常情况时,开启紧急排放模式控制,系统将全部打开风阀,本台适风柜大风量,不受面风速值的控制。

We provide laboratory for variable air volume systems CON-LABC with VAV fume hood control system CON-FHC, using the worl's most advanced VAV solutions through a digital contoller for laboratory supply exhaust, fume hood face velocity for strict monitoring control.

我们提供的实验室变风量体统CON-LABC与通风柜变风量控制系统CON-FHC,采用世界先进的进的VAV解决

方案,通过过数学控制器对实验室送排风、通风柜的面风速,进行严格的监视与控制。

Security no matter how to adjust the opening window, you can always precise control of the fume hood wind speed of 0.5m/s+20% of imports. At the same time the exhaust valve air flow tracking changes in the amount of wind to send the air valve to increase decrease exhaust volume to ensure that the design of the infiltration air flow is constant . thus ensuring a laboratory micro- negative pressure aiflow direction. System strong adaptability, energy consumption can be decline to fullyprotect the safety on this premise.

保障无论调节窗开度如何,始终可以控制遇风柜进口风速为0.5m/s。同时排放阀风量追踪送风阀的风量的

变化。增大或减小排风量,以保证设计的渗透风量恒定,从而保证实验室的微负压及正确的气流方向。系统适应性强,可以在充分保障安全的前提下降低能耗。
