1、空調通風系統的總體要效果，除了房間溫度、濕度達到設計要求外，使用房間的噪聲大小也同樣重要，是設計成功與否的關鍵之一。
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、空調通風系統主要噪聲源：
2. The main noise source of air conditioning and ventilation system:
2.1平時通風：排風機、送風機。
2.1 normal ventilation: air exhausting machine and air supply machine.
2.2空調系統：制冷機組，循環(huán)水泵 、冷卻塔、空調末端（風機盤管、空氣處理機組）2.3火災時：排煙風機、正壓送風機。
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人防通風系統：人防風機。
2.4 air defense ventilation system: air defense fan.

需要控制噪聲的設備主要為空調系統設備、平時通風設備；而人防通風設備及火災時排煙加壓風機因其僅在戰(zhàn)時或火災開啟，噪聲可不予控制。
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、要使使用房間達到室內允許噪聲標準，可從以下幾方面去控制：
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設備設置的位置及選型的優(yōu)化。
3.1 the location and selection optimization of equipment setting.
3.2風管系統設計優(yōu)化。
3.2 design optimization of the wind pipe system.
3.3設備的安裝減震及管道隔振。
3.3 the installation of shock absorption and vibration isolation of the pipe.
傳遞途徑上對通風設備噪聲抑制
Noise suppression of ventilation equipment in transmission route
(1)在通風設備的進、出風口上裝配恰當的消聲器。
(1) fitting the appropriate muffler on the inlet and outlet of the ventilator.
(2)通風設備設減振基座，進、出風口用軟管連接。
(2) the ventilation equipment is equipped with vibration damping base, and the inlet and outlet tuyere is connected with a hose.
(3)對通風設備做隔聲處理。如設備通風設備隔聲罩;在通風設備機殼內襯只聲材料;將通風設備設置在專門的通風設備室內，并設置隔聲門、隔聲窗或設置其他吸聲設施，或在通風設備室內另設值班室等。
(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)通風設備室的進、排氣通道采取聲措施。
(4) sound measures are taken for the inlet and exhaust passages of the ventilation equipment room.
(5)將通風設備布置在遠離要求安靜的房間。
(5) the ventilation equipment is arranged away from the quiet room.
