PURPOSE:To form a comfortable air conditioned spacing by a method wherein air outside or inside a guiding member having a parabolic guide surface made of light- and heat-shielding sheet material is sucked and injected toward a central part of the guiding surface and an air conditioner is installed in a zone enclosed by a filmy air flowed out of an outer circumferential edge of the guide member. CONSTITUTION:When an axial blower 2 is operated, air outside a guiding member 1 made of sheet material of light- and heat-shielding substance having ceramics for the space or the like mixed therein passes through a guard 26, enters from an air suction port 25 into a casing 21, strikes against a central part of a parabolic guiding surface 1a. The air is guided by a guide 28 and becomes a flow B along a guiding surface la and then the air is dispersed toward an outer circumferential edge 1c. Then, the air becomes a filmy annular air flow C from an entire circumference of the outer circumferential edge 1c and flows out slant downwardly. An air curtain is formed by this annular air flow C from the outer circumferential edge 1c of the guiding member 1 to a fixed wall 3. That is, a zone 9 is formed in a spacing 8 between the guiding member 1 and the fixed wall 3. In turn, an operating panel 50 is operated, an air conditioner 4 and a condensing device 6 are operated for a cooling operation so as to cool within the zone 9. |
