INSTALLATION OF VENTILATION FORCED IN SPECIAL FOR VEHICLES

摘要

The installation has a motor driven fan and ventilation outlets that may be formed as nozzles. Each fan is connected to a group of outlets made up of a central outlet (1) and at least two peripheral outlets (2) which are arranged around the central outlet. The outlets have a tubular housing (11,21) and a guide that is located in the housing and is made up of three guide ramps which guides the air flowing upstream and down stream of the outlets. The airflow is first guided in a radial plane, then in a helical direction along the length of an axis relatively central to the outlets.
