    The ventilation cabinet adopts the exhaust structure, which can discharge harmful gases, which is the premise of safety for our use In the whole process of using different equipment, there are different safety problems, so it will be helpful for us to understand these specific aspects correctly How to reduce the energy consumption of fume hood? Method 1: reduce the exhaust air volume outside the fume hood The application of this method mainly relies on the VAV system (variable air volume control system) It is mainly to reduce the height of the front door panel as much as possible in the operation process, that is, the lower the front door panel of the fume hood is opened, the smaller the volume of air discharged to the outdoor, and the less the supplementary air volume is required On the contrary, the higher the front door panel of the fume hood is opened, the larger the volume of air discharged to the outside and the larger the supplementary air volume is required For the fume hood equipped with VAV system, in order to ensure the safety of the experimental personnel, no matter the height of the door panel, the surface wind speed should reach 0.5m/s It is very complex and expensive to install VAV system, and it will take a long time to recover the cost of installation through its energy saving It is important that the VAV system will lose its energy-saving effect if the experimenter does not form a good habit to pay attention to the door opening height Method 2: use the tubeless clean air type fume hood This kind of fume hood is equipped with active carbon filter, which can absorb the chemical gas produced in the operation process After filtering, the clean air will circulate indoors instead of being discharged outdoors This kind of tubeless clean air type fume hood can be called "green fume hood" It has two outstanding advantages: first, it does not exhaust indoor air, thus saving a lot of energy consumption; second, it does not pollute the environment In addition, it is also very flexible, only need a power socket, can be placed in any position in the laboratory
