How to control the air conditioning and ventilation engineering noise? Environmental impact of noise and air-conditioning equipment to use the room for everyone to have been paying attention, this article from the installation and piping vibration isolation damping three positions and selection device settings, duct system design, optimization, equipment elaborated in the actual engineering design in how the equipment silencer, isolation, damping, making the surrounding buildings and the use of the room noise from reaching the specification requirements. 1, the overall effect of air conditioning and ventilation systems should, in addition to room temperature, and humidity to meet the design requirements Shanxi fan manufacturers, the use of the room noise level is also important Shanxi HVAC fans, is one of the keys to the success of the design. 2, air conditioning and ventilation system noise sources: 2.1 usual ventilation: exhaust fan, blower. 2.2 air conditioning system: cooling unit, circulating pumps, cooling towers, air-conditioned terminal (fan coil units, air handling units) 2.3 Fire: exhaust fan, positive pressure blower. 2.4 Ventilation air defense systems: air defense fan. Request to have the muffler Shanxi general ventilation system fan, you should first consider the low-noise fan, such as high efficiency, the circumferential speed of the impeller -M, and make it work at maximum efficiency point; we will take appropriate measures muffler, such as loading set up special muffler equipment. According to the nature of gas transportation in Shanxi fans different choice for different purposes Yuncheng fan. Transporting flammable gases such as Shanxi proof fans should be selected; transport pulverized coal powder should be selected fan; transport of corrosive gases should choose corrosion fan; in the case of work or delivery of high-temperature gas turbine high temperature should be chosen; transport concentration large dusty gas should be used for dust blower and so on.
