Abstract

L'invention a notamment pour objet une installation de ventilation comprenant : - un caisson central (2) avec un ventilateur (1) d'extraction ou d'insufflation d'air, - N gaines d'extraction ou d'insufflation d'air (41, 42, 43), chacune raccordée à un piquage d'entrée ou de sortie d'air dudit caisson central (2) ; - au moins une gaine de rejet ou d'entrée d'air (8), et - un régulateur de débit ( 5 1 " , 5 2 " , 5 3 "

Figure imga0001
) à ouverture de passage réglable pour chaque gaine d'extraction ou d'insufflation d'air (41, 42, 43). L'installation est caractérisée en ce que le caisson central (2) comporte des moyens d'auto-calibration aptes à déterminer et mémoriser in situ un coefficient de perte de charge associé à chaque gaine d'extraction ou d'insufflation d'air (41, 42, 43).

The invention particularly relates to a ventilation installation comprising: - a central box (2) with an air extraction or insufflation fan (1), - N air extraction or insufflation ducts (4 1 , 4 2 , 4 3 ), each connected to an air inlet or outlet of said central box (2); - at least one air rejection or inlet duct (8), and - a flow regulator ( 5 1 " , 5 2 " , 5 3 "
Figure imga0001
 ) with adjustable passage opening for each air extraction or supply duct (4 1 , 4 2 , 4 3 ). The installation is characterized in that the central box (2) comprises self-calibration means capable of determining and storing in situ a pressure loss coefficient associated with each air extraction or insufflation duct ( 4 1 , 4 2 , 4 3 ).
