Anhui Bench Fume Hood

For multiple parallel fume hood exhaust system VAV control system which is substantially the same as a single fume hood exhaust control systems, different thing is the speed sensor or fume hood doors on each fume hood monitor each bit t adjust fume hood electric exhaust manifold on the wide door, variable frequency drive controller conveyed by the static signal to automatically adjust a point before the main exhaust duct static pressure fan of the population, in order to keep constant, so as to achieve the purpose of changing the amount of exhaust . VAV fume hood system speed sensor is a very important element, in order to ensure the accuracy of the measurement, generally for temperature compensation in order to ensure reliable measurements in the laboratory temperature range. Also in the selection of the speed sensor, but also consider its durability and whether rapid response to changes in speed and so on. We can see from the above description, the core VAV fume hood exhaust system is variable air volume control system, but the system The cost is higher. According to the operation of some foreign systems, the payback period which cost more than 2 ^ 75 years. In addition, in order to ensure energy savings, with the operator it is essential.
