Provided are an outdoor unit for an air-conditioning apparatus and a method for assembling such an outdoor unit for an air-conditioning apparatus. Such an outdoor unit has a structure in which an oil separator is fixed to a partition plate with an auxiliary component. An outdoor unit for an air-conditioning apparatus includes a fan chamber, a machine chamber accommodating a compressor and an oil separator, and a partition plate partitioning off the fan chamber and the machine chamber. The oil separator is fixed to the partition plate with an auxiliary component. The auxiliary component includes a leg portion fixed to the partition plate, and a bed portion attached to the leg portion such that the bed portion is detachable, the bed portion supporting the oil separator.

A chilling unit includes a machine room unit to accommodate a compressor and a heat exchanger, and a plurality of air heat exchangers placed on top of the machine room unit. The air heat exchangers include a pair of air heat exchangers including two air heat exchangers opposite to each other in a lateral direction. They are inclined such that respective upper end portions of the two air heat exchangers have a spacing between each other greater than a spacing between respective lower end portions of the two air heat exchangers. In the lateral direction, the machine room unit has a top width greater than a heat-exchanger bottom width, the top width is one between side walls in a top face portion of the machine room unit, the bottom width is defined as a width between outer side faces of the respective lower end portions of the two air heat exchangers.

An outdoor unit of an air conditioner having an expansion valve unit. The outdoor unit of the air conditioner includes a compressor, a heat exchanger configured to exchange heat between outdoor air and refrigerant compressed by the compressor, an expansion valve unit configured to decompress the refrigerant discharged from the heat exchanger, a refrigerant pipe configured to deliver the refrigerant, which is decompressed and expanded by the expansion valve unit, to the indoor unit of the air conditioner, and a bracket configured to support the expansion valve unit. The expansion valve unit includes an expansion valve, a first connection portion configured to connect the expansion valve to the heat exchanger, and a second connection portion configured to connect the expansion valve to the refrigerant pipe. The expansion valve, and one of the first connection portion or the second connection portion are fixed to the bracket.
