METHODS FOR REPRESENTING THE TUBING OF VENTILATION/AIR-CONDITIONING PLANTS

Abstract

The representation of ventilation or air conditioning plants, particularly of the tubing, specifically require the ability to "see into space" or, more completely expressed, to make the connection between the plane and the space. For this reason, in the study program of the "Building Services Engineering" these types of installations have a privileged role. Thus, the students learn the representation in 2D of these plants during the study of the discipline Technical Drawing and further they learn the representation methods in 2D and 3D using the AutoCAD software – respectively the subroutine CAD VENT. Finally, the undergraduates study - as an alternative - the axonometric representation of these plants, by using the Allplan software. The last one offers also elements of the tubes (pipes) dimensioning. The paper presents teaching methods using concrete examples.
