Ceiling cassette air conditioner

Abstract

A ceiling cassette air conditioner includes: an external case 3 attached to a lower side of a ceiling-embedded casing 2, and forming an air inlet 9 with the ceiling U; an external panel 4 attached to a lower side of the external case 3, having an air blower 7 and a heat exchanger 8 inside, and forming an air outlet 10 with the external case 3 to discharge conditioned air passing the heat exchanger 8 in a ceiling-parallel direction; and wind direction adjusting vanes 5 provided on an outer periphery of the external panel 4 to adjust a discharge direction of the conditioned air discharged from the air outlet 10. During operation, the wind direction adjusting vanes 5 are turned in a clockwise and counterclockwise direction from a reference position M, which is defined such that the wind direction adjusting vanes flushes with the external panel 4 during operation stop.

1 . A ceiling cassette air conditioner comprising:
 an external case attached to a lower side of a casing embedded in a ceiling, and having an air inlet between the external case and the casing;   an external panel attached to a lower side of the external case, having an air blower and a heat exchanger inside, and having an air outlet between the external panel and the external case to discharge conditioned air passed through the heat exchanger; and   a plurality of wind direction adjusting vanes provided on an outer periphery of the external panel to adjust a discharge direction of the conditioned air to be discharged from the air outlet,   wherein during operation, the plurality of wind direction adjusting vanes are turned in a clockwise direction and in a counterclockwise direction from a reference position, wherein the reference position is defined to be a position during operation stop in which the plurality of wind direction adjusting vanes flushes with the external panel.   
     
     
         2 . The ceiling cassette air conditioner according to  claim 1 , wherein
 the plurality of wind direction adjusting vanes are individually turned in a range of 90° in the clockwise direction from the reference position and in a range of 90° in the counterclockwise direction from the reference position.   
     
     
         3 . The ceiling cassette air conditioner according to  claim 1 , wherein
 two wind direction adjusting vanes opposing to each other across the external panel, from among the plurality of wind direction adjusting vanes, are turned in a same direction by a same angle.   
     
     
         4 . The ceiling cassette air conditioner according to  claim 1 , further comprising a radiation panel that performs heat exchange by radiation at the center of a lower surface of the external panel.
