Referring to fig. 1, 2 and 10, according to some embodiments of the present invention, the outdoor heat exchangers 20 of the multiple sets of outdoor heat exchange compression systems are arranged along the up-down direction, so as to facilitate heat exchange between the outdoor heat exchanger 20 and the outdoor air, and the overall structure is compact, so that the outdoor heat exchanger 20 can be prevented from occupying too much space in the outdoor housing 10. For example, the outdoor unit 100 of the air conditioner includes two sets of outdoor heat exchange compression systems, the outdoor heat exchangers 20 of the two sets of outdoor heat exchange compression systems are respectively a first outdoor heat exchanger 21 and a second outdoor heat exchanger 22, the first outdoor heat exchanger 21 and the second outdoor heat exchanger 22 are arranged in the up-down direction, and the first outdoor heat exchanger 21 is located on the upper side of the second outdoor heat exchanger 22.

Referring to fig. 10, alternatively, each of the outdoor heat exchangers 20 extends in the horizontal direction to have the same length, so that space utilization inside the outdoor cabinet 10 is high and piping is convenient to arrange.

Referring to fig. 10, according to some optional embodiments of the present invention, the outdoor heat exchangers 20 of the multiple sets of outdoor heat exchange compression systems are arranged along the up-down direction, and the at least two outdoor heat exchangers 20 are different in height in the up-down direction, so that the heat exchange capacities of the at least two outdoor heat exchangers 20 are different and can correspond to outdoor heat exchange compression systems with different powers.

Referring to fig. 1, according to some embodiments of the present invention, an outdoor fan 90 is shared by a plurality of sets of outdoor heat exchanging compression systems, and when the outdoor fan 90 works, the air flow in the outdoor housing 10 can be accelerated, which helps the outdoor heat exchanger 20 of the plurality of sets of outdoor heat exchanging compression systems to exchange heat with air quickly. By sharing one outdoor fan 90 by a plurality of sets of outdoor heat exchange compression systems, the cost can be saved, and the occupation of the whole space can be reduced. For example, the outdoor housing 10 is provided with an outdoor air inlet and an outdoor air outlet, when the outdoor fan 90 rotates, the air outside the outdoor housing 10 can be sucked into the outdoor housing 10 from the outdoor air inlet, so that the outdoor heat exchanger 20 exchanges heat with the air inside the outdoor housing 10, and the air after heat exchange can be discharged out of the outdoor housing 10 from the outdoor air outlet under the driving of the outdoor fan 90.

The electric control part 40 of the outdoor heat exchange compression system with higher power generates relatively more heat, the electric control part 40 of the outdoor heat exchange compression system with the highest power adopts refrigerant cooling, the refrigerant cooling effect is better, and insufficient heat dissipation can be avoided. The electric control component 40 of the outdoor heat exchange compression system with the minimum power adopts air cooling, and the electric control component 40 of the outdoor heat exchange compression system with the maximum power adopts refrigerant cooling, so that the accurate control of the heat dissipation of the electric control component 40 of the outdoor heat exchange compression system with different powers can be realized.
