PROBLEM TO BE SOLVED: To provide an air blow out opening for supplying the air sent into a duct from a required position of the air conditioning duct and to provide an air conditioning method using the same. SOLUTION: The air blow out opening 1 is formed between duct constitutions 11 constituting the air conditioning duct 10 to form a supplied air flow channel. The air supply opening 1 is provided with an air introduction plate 2 with an angle of elevation toward an upstream side in the air supply direction, and the air introduced from the air flow channel by the air introduction plate 2 is blown out to the outside of the duct from a porous plate 3a forming a part of a peripheral wall 3. By adjusting an angle of elevation of the air introduction plate 2, an air volume blown out from the porous plate 3a can be adjusted. COPYRIGHT: (C)2006,JPO&NCIPI
