1. Reduce Exhaust Noise: Using a muffler can typically reduce exhaust noise by 30 to 50 decibels.
2. Reduce fan noise: Use a resistive chip silencer.
3. Sound insulation, noise reduction and sound absorption treatment of the computer room:
3.1 Sound insulation of the computer room: Except for the necessary interior wall observation windows connected to the observation room, the rest The windows must be removed, all holes and holes must be tightly sealed, and the sound insulation of the brick walls must be more than 40 decibels. The doors and windows of the computer room adopt fireproof and soundproof doors and windows.
3.2 Air inlet and exhaust: The air inlet must be equipped with a resistive piece silencer to naturally balance the volume of air entering and leaving the computer room and oachieve obvious ventilation and heat dissipation effects.
3.3 Sound absorption treatment: The five walls of the engine room, with the exception of the floor, are subject to sound absorption treatment. According to the spectral characteristics of the generator set, a perforated plate resonance sound absorption structure is adopted.
Vibration isolation: Through vibration isolation, the excitation force generated by the equipment is isolated by the vibration reduction device, so that the solid sound is effectively isolated.
Sound absorption: Use sound-absorbing materials to absorb sound energy and reduce reverberation in the computer room.
Sound insulation: Take sound insulation measures for the doors and windows of the generator room and replace them with professional soundproof doors and windows.
Soundproofing: install soundproofingSound dampening at the computer room inlet and exhaust ports to reduce noise leakage.
General ventilation and process air supply in the diesel engine room are carried out by HVAC professionals. Others are determined by the electrical major. To put it simply: When the diesel engine room is not producing electricity, the air supply and exhaust is provided by HVAC professionals and when the machines in the diesel engine room are operating, the power in process air is also provided at this time by the HVAC service; . As with process smoke extraction, these are determined by the electrical sector.
