PROBLEM TO BE SOLVED: To improve a maintenance and repairing characteristic in an air conditioning system in which conditioned air heat exchanged with an indoor device passes through a duct and is supplied from a blowing-out port at a ceiling surface into room by a method an air blowing-out grill is easily fixed to an air blowing-out port of the blowing-out chamber mounted at a back side of the ceiling to improve a workability and at the same time an air volume adjusting device in the blowing-out chamber is adjusted and a dust removing filter is cleaned. SOLUTION: A blowing-out chamber 26a at a back side of a ceiling is formed such that a blowing-out frame 34 and a blowing-out grill 35 are fixed in sequence to its blowing-out port 33. At this time, the blowing-out grill 35 can be removably engaged with the blowing-out frame 34 in one-finger touch by a latch mechanism comprised of a latch 52 and an engaging protrusion 53 having a striker, resulting in that an assembling of the blowing-out chamber 26a is facilitated. Further, this device has a certain convenience that in order to prevent a falling of the device, the blowing-out grill 35 is supported by a hanger means such as chains 65, 65, various kinds of works (such as a maintenance or the like) can be performed while being hung without performing complete removal of the blowing-out grill 35 and its re- installing operation can be easily carried out. |
