An outdoor unit of an air-conditioning apparatus includes: a terminal unit that is provided on an outer peripheral surface of a compressor, and electrically connects components provided in the compressor and outside the compressor; a side soundproof cover that covers the outer peripheral surface of the compressor except for the terminal unit; and a terminal cover that covers the terminal unit exposed from the side soundproof cover to the outside of the side soundproof cover, and soundproofs the terminal unit. The terminal cover is attached to the side soundproof cover such that the state of the terminal cover can be changed between a state in which the terminal cover covers the terminal unit and a state in which the terminal cover does not cover the terminal unit.

In an embodiment, a fan mounting assembly for use in refrigeration system includes a mounting body having a first side and a second side with a fan opening. The mounting body includes a collar extending from the second side of the mounting body around the fan opening, a flange extending outboard of the collar, and a plurality of retainers extending from the second side of the mounting body outward from the fan opening. Each retainer has a fastener opening extending therethrough. The fan mounting assembly further includes a motor mount and guard that includes a plurality of rings and a plurality of legs extending radially from a center portion. Each leg has a proximal end with a proximal eyelet formed thereon and a distal end with a distal eyelet formed thereon. The distal eyelet is configured to align with the fastener opening of a corresponding retainer.

There is disclosed an outdoor unit an outdoor unit that may attach a cover to a case by using a magnetic member and have an empty space formed between the case and the cover as large as the thickness of the magnetic member, wherein air or a sound-proof or meta material may be filled in the empty space and a cover for covering the case of the outdoor unit may include several pieces that are detachably connected with each other like Lego pieces, and the cover may be attached to the other area of an outer surface of the outdoor unit except the area having an inlet for sucking external air and an outlet hole for discharging the external air drawn into the outdoor unit via the inlet outside again.

A drainage tray may be provided for collecting condensate from a heat pump that is adapted to be mounted on a support. The support may be mountable to at least one supporting structure to carry the weight of the heat pump and the support. The drainage tray may include a peripheral edge portion defining a central recessed portion configured to collect condensate. A condensate outlet may be provided for removing the condensate from the tray. The drainage tray may be configured to be arranged between an underside of the heat pump and the support. The drainage tray may have a trapezoidal shape.

An outdoor unit of an air-conditioning apparatus includes a housing, a compressor disposed in the housing, an outdoor heat exchanger through which refrigerant supplied from the compressor flows, an air-sending device that sends air to the outdoor heat exchanger, an electric component box including an electric component that controls the compressor, a dividing plate that separates the compressor from an air-sending chamber accommodating the air-sending device, an electric component mount disposed above the compressor to partition a mechanical chamber accommodating the compressor from an electric component chamber accommodating the electric component box, and a support part for the electric component mount provided on an inner wall of the housing along an outer circumferential shape of the electric component mount to project toward an interior of the housing.

A grommet assembly includes a bolt assembly that has a head portion. A grommet includes a tapering bolt opening for accepting the bolt assembly. A projecting portion extends from a body portion and has an overhang adjacent a distal end. The bolt opening at least partially defines a radial gap between the grommet and the bolt assembly. The head portion of the bolt assembly is spaced from the distal end of the projecting portion by an axial gap.

An outdoor unit of an air conditioner includes a cabinet including a first plate and a second plate, a blower disposed inside the cabinet, and a blower cover covering the blower and an upper side of the cabinet. The first plate includes a contact area in contact with the blower cover in an outward direction of the cabinet, and the second plate includes a first non-contact area that is not in contact with the blower cover in the outward direction of the cabinet. The blower cover is disposed on one of four plates of the cabinet to reduce the noise generated due to the vibration of the cabinet by reducing the vibration transmitted from the blower cover to the cabinet.
