SMOKING AREA ISOLATION SYSTEM AND SMOKING AREA ISOLATION METHOD

WIPO Patent Application WO/2015/136691

A1

A smoking area isolation system for implementing a smoking area isolation method according to the present invention comprises: a boundary entrance/exit opening (20) that is formed in a smoking area separation boundary dividing a non-smoking room (16), which is a non-smoking compartment, and a smoking room (18), which is a smoking compartment, so as to link the non-smoking room (16) and the smoking room (18); an air supply/discharge device (32) that discharges air from the smoking room (18) while supplying air to the non-smoking room (16) so as to cause air to flow from the non-smoking room (16) toward the smoking room (18) at the boundary entrance/exit opening (20) and thereby generate a boundary passing flow (BPF); an air blowing device (24) that blows air from a position above the boundary entrance/exit opening (20) toward the smoking room (18) at a downward slanting direction so as to form an air curtain (AC) in the smoking room (18); and a blocking device (38) or a blocking plate (40) that blocks the flow of air from the smoking room (18) toward the boundary entrance/exit opening (20) through a gap (G) between the air curtain (AC) and the boundary entrance/exit opening (20) created by the slant of the air curtain.
