An outdoor unit of a refrigeration apparatus includes: a fan that generates an upward flow of air passing through a heat exchanger; an electric component box that accommodates a group of electric components; and a casing that includes a panel disposed at a predetermined position opposite to the electric component box. The panel is divided into at least a first panel and a second panel in a lateral direction as viewed from a front view of the panel. The first panel is opposed to at least part of the electric component box. The first panel is detachable from the casing while the second panel remains attached to the casing.

A fan unit includes: a fan casing having a long side corresponding to either a width or a depth of the fan casing, a short side corresponding to the other of the width or the depth, and an upper surface on which a blow-out grille is mounted; a fan housed in the fan casing and that blows out air from the blow-out grille; and a bell mouth comprising a cylindrical portion surrounding the fan inside the fan casing. The cylindrical portion includes two first arc regions each facing the short side of the fan casing, a second arc region facing the long side of the fan casing, and a guide portion disposed in at least one of the first arc regions. The guide portion includes an extended end portion.

Fan unit, and outdoor unit of air conditioner comprising fan unit

An outdoor unit for an air conditioner includes: a casing including a bottom plate that defines a bottom surface of the casing; a heat exchanger disposed in the casing; and an installation foot that supports the bottom plate from below. The installation foot includes: a support portion that supports from below an end portion of the bottom plate, a wall portion disposed on an outer side of the end portion of the bottom plate and that extends upward from the support portion, and a mount portion that extends from an upper end of the wall portion. The heat exchanger is mounted on the mount portion. The mount portion has a hole that extends through the mount portion in a height direction of the outdoor unit.

A heat source unit includes: a corrugated plate-like bottom frame in which ridges and furrows extend across the front and rear direction or across the right and left direction; and mounting feet. The mounting feet include: supports that support, from below, the furrows of supported ends of the bottom frame on sides that the ridges and the furrows can be seen; and walls disposed on outer sides of the supported ends and that extend upward from the supports. Water drainage passages, that drain water sticking to tops of the ridges of the supported ends to the supports, are disposed above the supports.

Heat source unit with corrugated bottom plate

A bottom frame () which constitutes a bottom surface of a casing () is divided into a main bottom frame () where a first compressor () is to be provided and a sub bottom frame () where a second compressor () is to be provided. The main bottom frame () is further divided into a first bottom frame () and a second bottom frame (). The first compressor () is to be provided on the first bottom frame (). A refrigerant circuit component () to be replaced or added in accordance with a capability or a function is to be provided on the second bottom frame ().
