PROBLEM TO BE SOLVED: To prevent the adhesion of oil to a ceiling panel material and prolong the life of a ceiling panel, by attaching an oilproof protective sheet to the topside of the ceiling panel positioned under the refrigerant pipe and the flare joint projecting from the flank of the main body where the refrigerant pipe from the outdoor machine of an air conditioner. SOLUTION: In an air conditioner, inlet refrigerant pipes and outlet refrigerant pipes 20 for a heat exchanger are arranged at the chamfered side faces of the four corners of the main body 2, and flare joints 21 and 22 are installed each at these tips so as to connect with the refrigerant pipes from an outdoor machine. At this time, the lower opening of the main body 2 is covered with the ceiling panel 98, and also the under section of the refrigerant pipes 19 and 20 arranged protectively and the flare joints 21 and 22 are covered with it. Then, an oilproof protective sheet 23 made of oil-resistant polypropylene resin material is attached and fixed to the corners applicable to the area under the flare joints 21 and 22, out of the topside of the ceiling panel 8. Hereby, the direct sticking to the surface of the ceiling panel material of the leaked oil is prevented. |
