How to reduce the energy consumption of fume hoods?

The fume hood adopts the exhaust structure, which can discharge harmful gases, which is the premise of safety for our use. Different equipment in the whole process of use, for security issues are not the same, so the correct understanding of these specific aspects, then it will be helpful for us all. How to reduce the energy consumption of fume hoods? Method one: Reduce the exhaust air volume outside the fume hood, the use of this method is mainly with the help of the VAV system (variable air volume control system), mainly in the operation process as far as possible to reduce the height of the front door panel, that is, the lower the front door panel of the fume hood is opened, the smaller the volume of air discharged to the outside, and the less the need for air supply. On the contrary, the higher the front door of the fume hood is opened, the greater the volume of air discharged to the outside, and the greater the amount of air needed. For the ventilation cabinet equipped with VAV system, in order to ensure the safety of experimental personnel, no matter what the height of the door panel, the surface wind speed should reach 0.5m/s. Installing a VAV system is complex and expensive, and it can take a long time to recoup the cost of installation through the energy savings it brings. Importantly, if the experimenters do not develop a good habit of paying attention to the height of the door, the VAV system will lose its power saving effect. Method two: Use a pipeless clean air type fume hood. The fume hood is equipped with an activated carbon filter, which can absorb the chemical gases produced during the operation. After filtration, clean air will be circulated indoors instead of being discharged outdoors. This kind of pipeless clean air type fume hood can be called as "green fume hood", it has two advantages: one is not exhaust indoor air, thus saving a lot of energy consumption; Second, it does not pollute the environment. In addition, it is very flexible, only requires a power outlet, can be placed anywhere in the laboratory.
