PROBLEM TO BE SOLVED: To provide an air conditioning system having an improved work execution performance, by providing freedom of installation direction of a duct for supplying plural rooms with conditioned air blown out from an indoor machine to easily install the duct under the floor. SOLUTION: An opening 81 is provided in a first floor 46, and heat insulating material 82 (board for installation of an indoor machine) having an fitting hole 85 is installed over this opening, and a T collar 92 is passed into the fitting hole from above, while the ventilation pipe 55 of a branch chamber 50 is set so that the tube 92c of this T collar is fitted inside, and both are integrally united. Then, an indoor machine 3 provided with an outlet 3F at it lower part is set up on the heat insulating material 82 by locating fittings 86 and 86 and fixing fittings 87 and 87. Since the tubular ventilation pipe is coupled with the tube of the T collar freely rotatably by 360 deg.C, the direction of installed supply duct coupled with the branch chamber becomes free, and the work execution performance can be improved. |
