PROBLEM TO BE SOLVED: To permit a common duct to be used for a cold air outlet duct and an exhaust hot air outlet duct by forming fitting portions of the cold air outlet duct and the exhaust hot air outlet duct to have the same shape for direct fixture to a roof plate. SOLUTION: A roof plate 8 of an air conditioner 1 is provided with a single cold air outlet 8a and two exhaust hot air outlets 8b which have the same shape as the cold air outlet 8a. A cold air outlet duct 12 or an exhaust hot air outlet duct 13, which is flexible and whose flange-like fitting portions 12a, 13a are shaped in the same form, are directly fitted to the positions of the outlets 8a, 8b of the roof plate 8, respectively, by means of screws. The number of the cold air outlet 8a and the exhaust hot air outlet 8b is determined in accordance with a set ratio of a cold air capacity from an evaporator and an exhaust hot air capacity from a condenser. In this way, a duct which is common for the cold air outlet duct and the exhaust hot air outlet duct can be used. |
