Plenum chamber muffler pipes at high flow air conditioning system used widely, which is characterized by simple structure, good muffler muffler frequency band effect, but a large resistance losses, generally applies to low flow high flow air conditioning system. Plenum chamber muffler pipes generally 20dB. Setting off in the plenum silencing effect can be increased at the same time to increase the pressure loss is generally no more than 4 Shanghai anechoic chamber plenum, Room 4 does not serve to improve over the role of the muffler. Best opening 1/3 the width between the chamber. Plenum chamber muffler pipes have characteristics of resistance, and its performance depends on the muffler sound-absorbing material properties. Airflow speed control 6 m / s or less. Duct plenum required system configuration and use of the remaining space is designed according to the specific conditions difficult to have a fixed form and size, silencer plenum specifications according to user requirements. Muffler outlet plenum air outlet plenum is an essential accessory end of the main air duct or directly through a hose connected to the plenum of the diameter section, here has a valve can be controlled into the static pressure air volume boxes, Shandong silencer plenum static pressure increase system stability Merry plenum, making Beijing more reasonable air distribution plenum chamber muffler, air conditioning to achieve the desired effect. Glass wool or other sound-absorbing materials, surface mount plenum has sound-absorbing material, can eliminate the noise outlet airflow, while preventing crosstalk adjacent room, eliminating volume 5-10dB (A) .ZHXS.XJY -2 is suitable for small B-side width of 200mm long back vent. With EVA foam or polyethylene foam sound-absorbing material gas ester. Material Standard thickness 10 mm .. B × l may be based on the size of the outlet provides:. Ф according to the selected depending on the diameter of the hose connector interface standard round feet; 150 150 200 250 320.A general size A = B + 100mm; H size according to the ceiling space height may be, but not less than ф + 100mm H or pipe degrees degrees plus 100mm. Vent length L is less than 2000mm. Width less than 200mm plenum |. Shandong silencer plenum | Dingrui air conditioning (certified merchants) by Wu Cheng Ding Rui Air Conditioning Equipment Co., Ltd.
