Abstract (en)
[origin: EP3862638A1] An outdoor unit including fans at two locations reduces noise caused by suction air. The outdoor unit includes: a housing; a bottom plate forming a lower surface of the housing, a top plate forming an upper surface of the housing, and a side wall provided between the bottom plate and the top plate to partition an internal space of the housing; a heat exchanger provided in the housing and on an inlet-port side; and fans provided in the housing and on an outlet port side. In the housing, an air flow passage is provided to extend from the heat exchanger to the fans. The fans are first and second fans that are respectively provided in upper and lower regions on the outlet port side in the housing. The air flow passage is defined by the bottom plate, the top plate, and the side wall located beside the fans. Cross sections of regions of the air flow passage that are located between central axes of the fans and the side wall have respective cross-sectional areas A, B, and C such that the cross-sectional area B < the cross-sectional area A < the cross-sectional area C is satisfied, where the cross-sectional area A is a cross-sectional area of a first cross section that is located between the central axis of the first fan and the top plate and is parallel to the bottom plate, the cross-sectional area B is a cross-sectional area of a second cross section that is located between the central axis of the second fan and the bottom plate and is parallel to the bottom plate, and the cross-sectional area C is a cross-sectional area of a third cross section that is located between the first cross section and the second cross section and is parallel to the bottom plate.
