PROBLEM TO BE SOLVED: To prevent drain water from freezing to have an adverse effect on a fan, heat-exchanger, or the like. SOLUTION: The bottom plate 2 of an outdoor unit is embossed to form a plurality of faces vertically in multistage and one main drain port 6 for discharging drain water from a heat-exchanger 3 is made through the lowermost plane of the bottom plate 2 or the plane directly under the heat-exchanger 3 while a plurality of sub-drain ports 7 are made through a plane located higher than the main drain port 6. Since the drain water is discharged through the sub-drain ports 7 even if it is not discharged through the main drain port 6, the drain water is prevented from freezing to have an adverse effect on a heat- exchanger, or the like. |
