<p><P>PROBLEM TO BE SOLVED: To obtain circulation effect and cool air feeling for producing an energy-saving and comfortable space, by generating energy for blowing a large air amount to a blowing-off space by inductive effect in an energy-saving manner from a small air amount energy necessary for generating a get from a blowing-off nozzle, by reducing projection into a room as a blower is provided under the roof, and by reducing operating sound generated from the blower. <P>SOLUTION: A main air duct 5 includes: an air duct connecting a first suction port 6 to a lower chamber 19 and a nozzle 10 via the blower 7 integrally provided for a ceiling side which is an upper surface of a blower device 1, via an upper chamber 9, and via a first connection air duct 8; and an air duct, as an induction air duct 11 composed by separating the nozzle 10 from a ceiling 2, connecting a second suction port 12 outside in the short direction of a straight tube type light source 4 via a second connection air duct 13 to a space between two nozzles 10. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
