Abstract

The aerating and ventilating system has a fresh air shaft (24) and exhaust air shaft (26) in a vertical shaft (12) and located vertically and parallel to one another. The fresh air shaft in an upper section has at least one fresh air inlet (28), and in a section below it at least one fresh air outlet (30). Between the fresh air inlet and outlet the fresh guiding in the fresh air shaft runs from the top downwards. The exhaust air shaft is similarly constructed but with the exhaust air guiding running from the bottom upwards.
