PURPOSE:To obtain sufficient heat insulating effect in spite of thin thickness and attain the miniaturization of a casing by a method wherein the foamed body of vinylidene chloride is employed for a heat insulating material arranged in the casing, in which a heat exchanger, a fan and the like are received. CONSTITUTION:In a ceiling-embedded type air-conditioning machine, indoor air, sucked by a centrifugal fan 8 from a suction grille 7 through an air filter 7 and a nozzle plate 12, is cooled or heated by heat exchange in a heat exchanger 14 and, thereafter, is discharged out of an air outlet port 6. Drain water, condensed in the heat exchanger 14, drops into a drain pan 13 while the drain pan 13 effects as a heat insulating material for preventing the downward radiation of heat of the heat exchanger 14. In this case, the drain pan 13 is formed of the foamed body of vinylidene chloride. According to this method, heat insulating performance of about 1.5 times compared with a heat insulating material made of foamed styrol is obtained whereby the thinning of the drain pan 13 can be contrived and the miniaturization of a casing can be realized. |
