METHODS OF REPRESENTING THE DUCTS OF AIR CONDITIONING SYSTEMS.

To achieve hygro-thermal comfort in buildings, an essential role belongs to air conditioning installations. Since the thermal agent is the air treated to appropriate parameters, the pipes through which the transport is ensured have large sizes, varying in the range of approximately 100-2000 mm. For this reason, pipe elements need a geometric study, especially where changes in direction, section or shape take place. Their representation is mandatory through views and/or sections, i.e. in double or triple orthogonal projections, but for an overall view of the installation are completed with 3D representation, through various drawing programs such as computer aided design.
