The generator room must be well ventilated to reduce noise

diesel fuelGenerator setIn the construction of computer rooms, how to reduce noise is a concern of many users and friends. In many computer room design links, Haixing Power believes that good ventilation design is the key. If ventilation is done well, the noise will naturally be small!

Since the diesel generator set requires a large amount of fresh air during operation, the exhaust and exhaust ducts of the machine room must be designed to meet the requirements. A large amount of noise is also spread out of the machine room from the air inlet and exhaust ducts. Properly designed air inlet and exhaust ducts are important links in reducing noise. Generally speaking, the air inlet and exhaust ducts of diesel generator sets use folded brick air ducts. The air inlet muffler and exhaust muffler have both inner cavities. Install sound-absorbing materials and perforated sound-absorbing panels to ensure that the unit can operate normally When running at rated power for a long time, the air inlet and outlet of the unit must reserve sufficient exhaust area according to the unit's usage requirements. A low-noise axial flow fan must be installed on the exhaust duct of the unit to ensure sufficient ventilation in the machine room. The above methods are expected to reduce noise by 25-30DBA.

Exhaust noise is the main noise source of the unit. Using two mufflers in series for secondary silencing is expected to reduce TL=30-40DBA. On the other hand, the exhaust pipe connection must have good sealing performance, and part of the noise is exhausted through the exhaust pipe. to the atmosphere.

In order to prevent the temperature of the machine room from rising and affecting the output power of the unit after the unit has been running for a long time, the exhaust pipe and exhaust muffler of the unit are insulated and insulated.

Only by constructing the machine room through the above means can good ventilation be ensured. On the one hand, it ensures the environment for operators, and on the other hand, it also solves the problem of noise, allowing the generator set to operate and provide sufficient power supply.
