1、空调通风系统的总体要效果，除了房间温度、湿度达到设计要求外，使用房间的噪声大小也同样重要，是设计成功与否的关键之一。
1, the overall effect of air conditioning and ventilation system. Besides the room temperature and humidity to meet the design requirements, the noise size of the room is also important, which is one of the keys to the success of the design.
2、空调通风系统主要噪声源：
2. The main noise source of air conditioning and ventilation system:
2.1平时通风：排风机、送风机。
2.1 normal ventilation: air exhausting machine and air supply machine.
2.2空调系统：制冷机组，循环水泵 、冷却塔、空调末端（风机盘管、空气处理机组）2.3火灾时：排烟风机、正压送风机。
2.2 air conditioning system: refrigeration unit, circulating water pump, cooling tower, air conditioning terminal (fan coil unit, air handling unit) 2.3 when fire: smoke exhausting fan and positive pressure fan.
2.4人防通风系统：人防风机。
2.4 air defense ventilation system: air defense fan.

需要控制噪声的设备主要为空调系统设备、平时通风设备；而人防通风设备及火灾时排烟加压风机因其仅在战时或火灾开启，噪声可不予控制。
The equipments that need noise control are mainly air conditioning system and usual ventilation equipment. However, the noise of civil air defense ventilation equipment and smoke exhaust pressurized fan is not controlled because of its opening in wartime or fire.
3、要使使用房间达到室内允许噪声标准，可从以下几方面去控制：
3, to make use of the room to meet the national standard of indoor noise, it can be controlled from the following aspects:
3.1设备设置的位置及选型的优化。
3.1 the location and selection optimization of equipment setting.
3.2风管系统设计优化。
3.2 design optimization of the wind pipe system.
3.3设备的安装减震及管道隔振。
3.3 the installation of shock absorption and vibration isolation of the pipe.
传递途径上对通风设备噪声抑制
Noise suppression of ventilation equipment in transmission route
(1)在通风设备的进、出风口上装配恰当的消声器。
(1) fitting the appropriate muffler on the inlet and outlet of the ventilator.
(2)通风设备设减振基座，进、出风口用软管连接。
(2) the ventilation equipment is equipped with vibration damping base, and the inlet and outlet tuyere is connected with a hose.
(3)对通风设备做隔声处理。如设备通风设备隔声罩;在通风设备机壳内衬只声材料;将通风设备设置在专门的通风设备室内，并设置隔声门、隔声窗或设置其他吸声设施，或在通风设备室内另设值班室等。
(3) sound insulation treatment for ventilation equipment. For example, the ventilation cover of the equipment, the sound material inside the ventilating equipment shell, the ventilating equipment in the special ventilating room, and the soundproof door, the sound insulation window or the other sound absorption facilities, or the duty room in the ventilating room.
(4)通风设备室的进、排气通道采取声措施。
(4) sound measures are taken for the inlet and exhaust passages of the ventilation equipment room.
(5)将通风设备布置在远离要求安静的房间。
(5) the ventilation equipment is arranged away from the quiet room.
