Many users often encounter many problems in the process of using air duct, and they will feel that it is the design problem of air duct. Today, Xiaobian will talk to you about the key points of air duct system and air duct design.
Classification of air duct system: air duct of dust removal system, air duct of ventilation system, air duct of smoke control system and air duct of air conditioning system.
Classification block diagram of air duct system: according to the shape of air duct, the material of air duct, the air velocity in air duct and the function of air duct.
Design principle of air duct system: reasonably and correctly divide ventilation and air conditioning air duct system; Reasonably arrange the air duct system; Reasonable zoning and pipeline layout and connection; Coordinate with the building design; Reduce the flow resistance of air duct system; Comply with fire code; Insulation of air duct; Design the end face size of the air duct according to the noise requirements; If the air duct may produce condensed gas, the air duct shall be set with a slope of ≮ 0.005; Standard air duct and air duct accessories p354 ~ 355; Wind speed in air duct of ventilation and air conditioning system; Selection of fan, air volume: the air volume of the selected fan > the design flow of the system; Connection between fan and air duct.
