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.

Outdoor unit for air-conditioning apparatus

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.

Outdoor units for air conditioners

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.

Refrigerant distributor, and heat pump device having the refrigerant distributor

An outdoor unit includes: a lower heat exchanger having a first heat-transfer tube; an upper heat exchanger provided above the lower heat exchanger, including a first-row heat-exchanger core and a second-row heat-exchanger core, and a second heat-transfer tube; and a reinforcing member supporting the upper heat exchanger, wherein the reinforcing member includes a first supporting tab supporting the bottom of the second-row heat-exchanger core; a second supporting tab supporting the lower side surface of the second-row heat-exchanger core and formed integrally with the first supporting tab; a third supporting tab providing a gap between the first-row heat-exchanger core and the second-row heat-exchanger core and formed integrally with the first supporting tab; an engaging tab holding the first heat-transfer tubes and formed integrally with the third supporting tab; and an engaging tab holding the second heat-transfer tubes and formed integrally with the third supporting tab.
