PROBLEM TO BE SOLVED: To contrive energy saving in work or maintenance, thinning of constituting members, lowering of noise and the like by a method wherein the lower ends of supporting pillars, having a connecting part at the end of the same, are permitted to be removed from both end parts of a frame while at least two sets of air conditioners, having different outputs, are attached to the trestle so that the air conditioner, having a smaller output, is attached above the other air conditioner having a larger output. SOLUTION: The supporting area of a hanging frame can be reduced by arranging two sets of indoor machines 4, 5, having different outputs, on the hanging frame so as to be vertically superposed on each other. On the other hand, the hanging frame can be constituted of a heavy structure in order to prevent vibration on the circumference of the indoor machines 4, 5 from occurring due to vibration at the time of operating the indoor machines 4, 5. Further, the indoor machines 4, 5, the connecting part of ventilation ducts 17, 18 for air conditioning, the connecting part of a suction duct 22 for air conditioning and the like are arranged in the ceiling of a corridor 6 or the ceiling of a corridor in the close vicinity of living rooms. Accordingly, centralization of maintenance can be achieved whereby installation work and piping work can be effected easily. |
