The main performance is to eliminate air noise generated by wind flow, is a noise reduction facilities, mainly applied to central air conditioning, air conditioning units and other equipment in the plenum chamber muffler, then this muffler plenum structure What are the characteristics of it? Silencer plenum material can be selected within the post upon request rockwool, glass wool and other sound-absorbing material, the surface of the sheet metal or non-fired glass, steel, superior corrosion resistance. Control wind speed within 2.5 may be appropriate if the volume is too large may have to raise about the wind on the length of the generally greater than 1 meter have no other mandatory requirements (zjh112275) 4, height × depth = cross-sectional area of ??the plenum chamber muffler plenum, the plenum cross-section Area × 2.5m / s = fan flow, as with height and depth how? air volume units L ÷ 3 m / s, you get the plenum area of ??a surface, then you according to your height silencer plenum house design, if it is four meters, but your unit is 2 meters high, at about 0.5 meters minus the soft joints, stay above 0.5 meters high, that your plenum is only 1 meter, then you can determine the width, the With two numbers, the third number will be easy to determine where the most important is to look at their air-conditioned room enough position if enough position to try for big points! ! The method of calculating the length is the same, you know the width, then multiply the length of the width you do not also have an area of ??it? This area is also equal to L / 3, but the surface wind speed in the institute where the access 2m / s, and if enough space on the big point of it.
