Is there sound-absorbing cotton in the air inlet shaft 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 buckle 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 50mm thick sound-absorbing cotton. The outer wall uses an aluminum buckle perforated ceiling as the wall sound-absorbing material. After the sound insulation treatment of the computer room, the ventilation and heat dissipation problem in the computer room must be solved. The air inlet should be set on the same straight line as the generator set and air exhaust outlet. The air inlet should be equipped with a resistive piece muffler. Since the pressure loss at the air inlet is also within the allowable range, the air volume in and out of the machine room can be naturally balanced, and the ventilation and heat dissipation effect is obvious. If sound-absorbing cotton is used in the air inlet shaft, the heat dissipation effect will be affected.
