Is there sound-absorbing cotton in the air inlet duct of the generator room?

No. Sound-absorbing cotton is used in the generator room, and sound-absorbing equipment will be used in and out of the air shaft. The generator room is designed with a sound-absorbing ceiling. The ceiling adopts special sound-absorbing keels and is covered with 50mm thick high-quality sound-absorbing cotton as sound-absorbing material. Aluminum loop ceilings with a perforation rate >20% are used as surface protection sound-absorbing materials. The wall absorbs sound. In order to prevent sound from penetrating the wall and transmitting to the outside world, it is necessary to install a sound absorber on the wall. The sound absorber is made of 50 mm thick sound-absorbing cotton. The exterior wall uses an aluminum. loop perforated ceiling as sound-absorbing material of the wall. After the sound insulation treatment of the computer room, the ventilation and heat dissipation problem in the info roomrmatics must be resolved. The air inlet must be placed on the same straight line as the generator set and the air exhaust outlet. The air inlet must be equipped with a resistive piece silencer. Since the pressure loss at the air inlet is also within the allowable range, the air volume entering and leaving the engine room can be naturally balanced, and the ventilation and heat dissipation effect is obvious. If sound-absorbing cotton is used in the air inlet duct, the heat dissipation effect will be affected.
