Abstract: An air-conditioning-apparatus outdoor unit includes a casing, a heat exchanger disposed in upper part of an inner space of the casing, a bottom plate located at a bottom of the casing and having a drain hole through which drain water that is generated on the heat exchanger is discharged outside, a support disposed in the inner space of the casing and supporting the heat exchanger in the upper part of the inner space of the casing, and a drain structure disposed under the heat exchanger and guiding the drain water to the bottom plate.

Abstract: An outdoor unit for an air-conditioning apparatus is provided in which heat-exchanger units can be arranged such that a heat exchanger has a further increased capacity in a casing of a limited size while the volume of air to be fed to the heat exchanger is maximized. An outdoor unit for an air-conditioning apparatus includes a casing having a rectangular plan-view shape formed of a front portion, a left portion, and a rear portion; a heat exchanger provided in the casing and including a plurality of parts each having a rectangular plan-view shape; and a plurality of air-sending fans provided above a plurality of air inlet spaces, respectively, the air inlet spaces each being provided on an inner side of a corresponding one of the plurality of rectangular parts of the heat exchanger.

Abstract: A refrigerant distributor includes an inflow portion made of aluminum into which refrigerant flows through an inflow pipe, and a distributing portion made of aluminum that distributes incoming refrigerant to a plurality of outflow pipes. The distributing portion includes a main body portion connected to the inflow portion, and a plurality of outflow portions connected to the outflow pipes. The outflow portions are protruded from the main body portion, and are formed integrally with the main body portion.
