Breathability of Bag Air Duct

Understand the bag Air Duct permeability and permeability

1，what does the bag air duct permeability mean? The main component of fabric bag air duct is made of special material-polyester fiber, and the permeability is equal to the air permeability of ordinary fabric, the pressure in the duct is 125Pa, when the air permeability of 1 square meter surface area of fabric bag air duct reaches 1 CFM (1 CFM = 1.68 M3H) , the air permeability of the bag air duct is 1 Ch/t 2. The conversion unit can be obtained as follows: 1 CFM/ft 2 = 18 m3/h/M 2, in our country, we usually reduce the unit“M 3/h/m 2” to“Mm/s”, so: 1 CFM/F 2 = 18 m 3/h/M 2 = 5 mm/s II, the importance of selecting the material of bag air duct,

2，one of the characteristics of the bag air duct is that the air volume of the equipment through the bag air duct transmission into the working area, there are two ways: first, through the infiltration of fiber materials (not perforated way) , second, through the air around the uniform distribution of jet holes (openings or nozzles) . Among them, the most commonly used way of opening or nozzle, the general amount of air infiltration can only be used to prevent the formation of condensation, which is not the reason why the duct does not produce condensation, only 5% -10% of the total air volume of the system or less (except for the selection of pure infiltration mode air supply) . If the amount of air permeability in the air too much heat exchange, will cause a fixed cooling fee at high altitude, therefore, in different occasions, should choose different permeability material (and different air way) , to the same project, in different areas or different installation height, the need to choose the way the air outlet should also be different.
