<p>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 said duct elements of the first duct type; and connects said duct elements of the second duct type with connection duct elements in accordance with the connection of the corresponding duct elements in the original ventilation system, whereby a converted representation of the ventilation system is obtained. <IMAGE></p> |
