Natural light/ventilation cupola having an extremely high ventilation performance

摘要

Technical problem of the invention: Attempts to find for buildings with a full-time or intermittent requirement for a high degree of ventilation, rather than a ducted, artificial and always mechanically operated air supply and discharge, a ventilation system which is coupled with the inflow of large quantities of natural light and acts largely by natural air flow, but can also, particularly if the need arises, perform very highly. Solution of the problem: Duct-free, high-performance ventilation system with minimal construction and operation costs by the combination of methodically arranged air and light shafts with large, high-performance drum-type or propeller fans with a simultaneously high yield of natural light. Application areas: industrial buildings requiring a high degree of ventilation and natural light, above-ground garages enclosed on three or four sides, underground garages between vertically offset levels, underground garages in special cases where it is possible to feed large quantities of supply air to the bottom of the building naturally, a silo-type building with no windows and requiring air and light, and patios (air wells) which are enclosed on all sides and have special requirement for a natural-light atmosphere.
