<p>The invention concerns a ventilation means (10) comprising at least one fresh air intake duct (11, 110), and said ventilation means (10) comprising a means producing air flow circulation, fresh air being introduced through the intake duct into a room space. The ventilation means comprises a blower means (22, 220a) and/or (220b) or equivalent producing air circulation and disposed in the space defined within themselves by a first heat transfer and/or filtering circle (19, 190) and a second heat transfer and/or filtering circle (19, 190) and a second heat transfer and/or filtering circle (20, 200). The blower (22, 220a and/or 220b) or equivalent is disposed to move and transport part of the air from the area (A2 and/or A2', or A20' and/or A20'') on the intake side of the blower (22, 220a and/or 220b) to the area (A1; A10' and/or A10'') on its delivery side and thence through the ribbed surfaces of the heat transfer circle on the delivery side of the blower (22, 220a and/or 220b) to an area (A3) in the ventilation means (10) and further into the room space, and from the area (A1; A10' and/or A10'') by an induction duct (30a and/or 30b; 300a and/or 300b) to a point adjacent to, and advantageously above, the fresh air duct (11 and/or 12; 110 and/or 120), whereby the air flow coming through said induction duct that has been produced by the blower induces and attracts fresh outdoor air coming through the fresh air duct (11 and/or 12; 110 and/or 120). The invention also concerns a ventilation procedure.</p> |
