Abstract
A method for converting a representation of a ventilation duct system in a computer readable form from a first duct type to a second duct type, such as circular and rectangular ducts. The method identifies straight duct elements in the system, calculates an equivalent size of one or several duct elements of the second duct type to provide the same performance as the duct elements of the first duct type; and connects the duct element of the second duct type with connection duct elements in accordance with the connection of the corresponding elements in the original ventilation system, whereby a converted representation of the ventilation system is obtained.
