PURPOSE:To install an air conditioning device of ceiling type in the ceiling in a good-looking manner without a sense of oppression, by installing the air conditioning device in the ceiling by fitting all the edges of the top plate of a device in the wall surface around the hole of a ceiling. CONSTITUTION:Hangers 37-40 are fitted to a beam 49 in the hole 48 of a ceiling, and a device body 1 is set in the wall surface 51 around the hole 48 of a ceiling, interposed by a heat insulating material 31, so that the whole edge 50 of the top plate 20 of the device is contacted to the well surface 51 around the hole 48 of the ceiling. Then nuts 41-44 are screwed in the hangers 37-40, respectively, tightened up in order to adjust the device body 1 to get it horizontal by compressing the heat insulating material 31. By this method, the device body 1 can be installed in the ceiling so that the space 52 above a ceiling board 47 and the space 53 in a room are completely sealed up. As the hole 48 in the ceiling is hidden by the device, the ceiling is kept in a good-looking manner. Besides, a sense of oppression can be removed, because the device body 1 is installed closely in the ceiling board. |
