DN series efficient silencer

At present, ship air conditioning and ventilation systems mostly use centralized air supply all air systems to achieve cabin air environment control. There are two main sources of noise: one is the noise generated by the operation of (combination) air conditioners, ventilators, and other equipment; The second is the regenerative noise generated by the airflow in the air ducts and equipment, including the noise generated by the air ducts and air vents. Therefore, noise control needs to be approached from two aspects: on the one hand, optimizing system design to reduce noise from the sound source; On the other hand, measures such as sound absorption and noise reduction are taken to control the propagation of noise, which to some extent attenuates the noise to a lower value. In the air conditioning and ventilation system, the air vents require airflow to pass through. In this case, vibration isolation and noise reduction schemes are no longer sufficient at certain locations. In this case, we usually install silencers on the ventilation ducts to reduce noise. Josun air conditioner is a specialized high-efficiency muffler developed according to the GB/T 25516-2010 standard for various ventilation systems. It has the characteristics of good noise reduction effect, low air resistance loss, and easy installation. Widely used in various equipment rooms, garages, ships, and offshore platforms.
