Dear member,
It is general practice to provide 3 mtrs Acoustic insulation in supply and return duct from AHU. Irrespective of AHU capacity. i.e CFM. However, low capacity AHU/FCU/Split Ducted unit may not required upto 3mtrs acoustic insulation. Hence, on what basis acoustic insulation shall be provided upto 3mtrs or less?
