METHOD AND DEVICE FOR REALIZING THE VENTILATION OF A VENTILATED BUILDING BY LOW PRESSURE, ESPECIALLY A FRESH LIVESTOCK

摘要

P According to the invention, the air is introduced into the room in a direction of substantially horizontal blowing, and with a substantially constant introduction rate so as to obtain a blast range of between one quarter and one half of the width of the room. For this purpose, the ventilation device comprises an air inlet blower 1 in the room, shutter means 3 making it possible to modify the air inlet area of the mouth 1, a window life sensor. air 8 at the outlet of the mouth, control means 10 of the closure means 3 and a control circuit 11 adapted to vary the air inlet surface according to the measurement made by the detector 8 so as to to maintain a substantially constant value of the air inlet velocity in the room. / P P Ventilation of buildings ventilated by depression, particularly poultry rooms. / P
