3、系統(tǒng)風(fēng)閥和風(fēng)機(jī)整體聯(lián)鎖，實(shí)現(xiàn)氣流的有序流動(dòng)，平衡系統(tǒng)風(fēng)量，防止氣流反串、倒流。


The system adopts static pressure sensor automatic frequency conversion control or PLC programming control, static pressure sensor automatic frequency conversion, control can be based on the number of open ventilation equipment changes, the induced static pressure is converted into 0-10v electrical signal input frequency converter to automatically adjust the fan frequency, so that the fan's exhaust air volume is matched with the actual exhaust air volume, thus ensuring the exhaust air effect and achieving the effect of energy-saving and noise-saving; 2. Each fume hood shall be equipped with an electronic air volume control valve. The control switch, frequency conversion control system and fan linkage can realize the control of one or more ventilators under the same working condition. The Air Volume Control Valve uses the digital display adjustable angle electronic air volume control valve, and has the memory function then may remember this adjustment angle, next time opens still adjusts to the design angle. 3, the System Air Valve and the whole fan interlocking, to achieve the orderly flow of air flow, balance the system air flow, to prevent cross-flow, reverse flow. Vav Control System 1, the system uses static pressure sensor automatic frequency control, static pressure sensor automatic frequency control can be based on the number of open ventilation equipment changes, the induced static pressure is converted into 0-10v electrical signal input frequency converter to automatically adjust the fan frequency, so that the fan's exhaust air volume is matched with the actual exhaust air volume, thus ensuring the exhaust air effect and achieving the effect of energy-saving and noise-saving; 2. Each fume hood shall be equipped with a venturi variable air volume air valve. The control switch, frequency conversion control system and fan linkage can realize the control of single or multiple ventilators under different working conditions. VVVV Valve Adopts Venturi Valve with adjustable angle digital display, and memory function can remember the angle of this adjustment, the next time open still to the design angle. 3, the System Air Valve and the whole fan interlocking, to achieve the orderly flow of air flow, balance the system air flow, to prevent cross-flow, reverse flow.
