Product Description
Control scheme of variable air volume butterfly valve for fume hood
Working principle of variable air volume control system: Variable air volume control is to adjust the supply and exhaust air volume of the system by adjusting the opening of the ventilation cabinet window and door in the laboratory, ensuring that no matter how the window opening is adjusted, the wind speed on the ventilation cabinet surface can always be accurately controlled to be 0.3-05m/s
Solution for variable air volume Venturi valve in fume hood
Variable air volume control system: Variable air volume control is achieved by adjusting the opening of ventilation cabinet windows and doors in the laboratory. Regardless of the adjustment of window opening, the system can always accurately control the wind speed on the ventilation cabinet surface to be 0.3-05m/s
UBC fume hood adaptive solution
Principle of UBC adaptive system: Based on VAV variable air volume, a detector is installed on the fume hood to monitor whether there is anyone moving in front of the fume hood. When someone is operating, a constant air inlet speed of 0.5m/s is maintained, and when there is no one, the air inlet speed is 0.3m/s. On the basis of VAV, energy consumption is greatly reduced again
Ventilation cabinet window lifting system
Working principle of the fume hood window lifting system: Based on the UBC adaptive system, by setting the window to automatically lower when the window automatically descends, the exhaust air volume of the fume hood is reduced to the minimum value, greatly reducing energy consumption again
