Abstract

The invention relates to a device (1) for generating an air wall across a passage opening (100), which passage opening (100) has lateral edges and a top edge, comprising: a first and second blowing device (10, 20), arranged at the lateral edges in such a way that planar air streams are blown over the height and respective parts of the width of the passage opening (100); wherein the device (1) is provided with regulating means (13; 23) for regulating the blowing speeds of the blowing devices; and wherein the first blowing device (10) and the second blowing device (20) are provided with secondary blower slits (12; 22) which are parallel to the respective primary blower slits (11; 21), which secondary blower slits (12; 22) are connected to secondary means for drying and/or heating air to be blown.

Dependent claims

Device (1) for generating an air wall across a passage opening between a first space and a second space, which passage opening (100) has a first lateral edge, a second lateral edge and a top edge, the device (1) comprising:

a first blowing device (10) with a first primary blower slit (11), suitable for being arranged at the first lateral edge of the passage opening (100) in such a way that a first substantially planar air stream is blown over substantially the entire height and at least a first part of the width of the passage opening (100);
and
a second blowing device (20) with a second primary blower slit (21), suitable for being arranged at the second lateral edge of the passage opening (100) in such a way that a second substantially planar air stream is blown over substantially the entire height and at least a second part of the width of the passage opening (100);
wherein the device (1) is further provided with regulating means (13;
23) for regulating the respective blowing speeds of the first blowing device and the second blowing device;
and
wherein the first blowing device (10) and the second blowing device (20) are provided with secondary blower slits (12;
22) which are parallel to the respective primary blower slits (11;
21), which secondary blower slits (12;
22) are connected to secondary means for drying and/or heating air to be blown.

Method for screening a passage opening (100) between a first space and a second space by means of an air wall, which passage opening (100) has a first lateral edge, a second lateral edge and a top edge, the method comprising:

generating a first substantially planar air stream over substantially the entire height and a first part of the width of the passage opening (100) by means of a first blowing device (10) with a first primary blower slit (11), arranged at the first lateral edge of the passage opening (100);
and
generating a second substantially planar air stream over substantially the entire height and a second part of the width of the passage opening (100) by means of a second blowing device (20) with a second primary blower slit (21), arranged at the second lateral edge of the passage opening (100);
and
generating respective secondary air streams by means of secondary blower slits (12;
22) which are provided in the first blowing device (10) and the second blowing device (20) and are parallel to the respective primary blower slits (11;
21), wherein the air to be blown through the secondary blower slits (12;
22) is dried and/or heated;
wherein the respective blowing speeds of the first blowing device and the second blowing device are regulated by regulating means (13;
23) in such a way that the first air stream and the second air stream cover the width of the passage opening (100), and that the occurrence of turbulence is minimized in an area where the first air stream and the second air stream meet.
