And the housing accommodating the heat exchanger and the fan, one end in the width direction of the housing, and the other end in the width direction intersect each other in the width direction. A plurality of handles provided in pairs apart from each other in the depth direction of the housing, and a first handle provided at one end of the handles in the width direction is provided in the width direction and in the width direction. A plurality of pairs are provided at positions separated in the height direction intersecting the depth direction, and the second handle provided at the other end of the handles in the width direction is located at the uppermost portion in the height direction. Only a pair is provided at the height position between the first handle provided and the first handle provided at the lowermost part in the height direction, and is provided in the width direction as compared with the fan. A control box housed in the housing is further provided on the other side, and the second handle is provided at a position in the width direction corresponding to the position of the control box.

According to such an outdoor unit, on at least one of one side in the width direction and the other side in the width direction of the housing, handles provided in pairs in the depth direction are separated in the height direction. There are multiple pairs. Therefore, for example, when the outdoor unit is transported (carried in and out) using the stairs, the worker on the upper stage side of the stairs can grasp the handle provided on the upper part. Alternatively, the worker on the lower side of the stairs can grip the handle provided at the lower part. As a result, the worker is not forced to take an unreasonable posture when transporting the outdoor unit.
Further, by providing only a pair of second handles on the other side in the width direction between a plurality of pairs of first handles, the cost of installing the handles can be reduced as compared with the case where a plurality of pairs of second handles are provided. ..
Further, since the control box has an electronic device, it is difficult to secure a space for providing a handle at the position where the control box is provided. By providing only a pair of second handles, it is possible to solve the problem of securing the installation space for such handles. Further, if a large number of handles are provided at the position where the control box is provided, the possibility that rainwater or the like infiltrates into the housing from the position of the handles increases. Therefore, by reducing the number of second handles installed, the possibility of water entering the housing can be reduced. In addition, the control box is heavier than the fans. Therefore, by providing the second handle at a position higher than the first handle provided at the bottom, it is necessary for the operator to lift the other side in the width direction of the housing on which the control box is installed to a higher position. Is gone. Therefore, the outdoor unit can be easily transported without forcing the worker to take an unreasonable posture.

Further, in the above aspect, the dimension of the distance between the handles provided in a plurality of pairs at the positions separated in the height direction in the height direction may be one half or more of the maximum diameter of the fan. ..

Multiple pairs of handles are provided at such positions, and when the outdoor unit is transported using the stairs, the worker on the upper side of the stairs grips the handle on the upper side, and the worker on the lower side of the stairs holds the handle on the lower side. By grasping the stairs, the operator can easily carry the outdoor unit without being forced into an unreasonable posture.

Further, in the above aspect, the handles provided in a plurality of pairs at positions separated in the height direction are above and below the virtual line so as to sandwich the virtual line extending in the width direction through the rotation center of the fan. It may be provided in and.

By providing a plurality of pairs of handles at such positions, it is possible to secure an installation space for the handles without interfering with the fan. In addition, when transporting the outdoor unit using the stairs, the worker on the upper stage of the stairs grips the handle on the upper stage, and the worker on the lower stage of the stairs grips the handle on the lower stage, which makes it impossible for the worker. The outdoor unit can be easily transported without being forced to take a proper posture.

The air conditioner according to one aspect of the present invention includes the above-mentioned outdoor unit and an indoor unit in which a refrigerant circulates between the outdoor units.

According to such an air conditioner, a plurality of pairs of handles are provided in the housing of the outdoor unit at positions separated in the height direction, so that, for example, when the outdoor unit is transported using a staircase. The worker will not be forced into an unreasonable posture.
