2, static pressure box general old engineer experience is 5 ~ 10db ((a) / m, impedance composite type (as the air conditioning ventilation system is generally used this) silencer 10 ~ 15db ((a) / m.

4, height × depth = static pressure box section area, static pressure box section area × 2.5m/s = fan volume, to the height and depth how to match, let's master your own ~~

5, use your unit's air volume L÷3 m/second, you can get your static pressure box a face of the area, then you can rely on your house's height, if it's 4 meters, but your unit is 2 meters high, in subtracting soft connector about 0.5 meters, on top leave high 0.5 meters, then your static pressure box is only 1 meter high, then you can determine the width, with two numbers, the third number will also be simple determined, here the first thing is to see your own air conditioning machine room enough not enough direction, if enough direction will try to be the largest possible point!!

6, static pressure box thickness is better than 600mm, section wind speed less than 2m/s, other attention to take out direction and access direction there is a bit of air flow buffer zone, once in Shanghai and China East House teacher brother grassroots when, teacher brother told me China East House boss strongly advise not to use static pressure box, cost high resistance large, there are conditions to try using trousers three through to silence elbow or pipeline silencer.
