Abstract (en)
[origin: EP3845819A1] An outdoor unit includes plural machine units, an air-sending device, and a heat exchanger. The machine units each accommodate a machine chamber storing a machine part. The air-sending device is installed in an air-sending chamber positioned between partition walls of the machine units, and is configured to provide an air flow. The heat exchanger is installed upstream of the air-sending device, and is configured to exchange heat between refrigerant and air sent by the air-sending device. At least one of the partition walls of the machine units has a first region, a second region, and a third region. The first region is positioned close to the heat exchanger, and is inclined from a position close to the heat exchanger toward a rotation axis of the air-sending device. The second region is positioned downstream of the first region, and is inclined at an angle that is smaller than an angle of the first region. The third region is positioned downstream of the second region, and is inclined at an angle that is greater than the angle of the second region.
