How to Control Noise in Air Conditioning and Ventilation Engineering Design
1、 The overall effectiveness of the air conditioning and ventilation engineering system depends not only on meeting the design requirements for room temperature and humidity, but also on the noise level of the room used, which is the key to the success or failure of the design.
2、 The main noise sources of the air conditioning and ventilation engineering system are:
1. Regular ventilation: exhaust fan, supply fan.
2. Ventilation and air conditioning engineering system: refrigeration unit, circulating water pump, cooling tower, air conditioning terminal (fan coil unit, air handling unit).
3. In case of fire: smoke exhaust fan, positive pressure supply fan.
4. Civil air defense ventilation engineering system: civil air defense fan.
The equipment that needs to control noise mainly includes air conditioning and ventilation engineering system equipment, as well as regular ventilation engineering equipment; The equipment for civil air defense ventilation engineering and the pressurized fan for ventilation and smoke exhaust engineering in case of fire can only be turned on during wartime or fire, and the noise cannot be controlled.
