Further, by providing the outdoor fan 30, when the air conditioner outdoor unit 100 works, the outdoor fan 30 can introduce the air flow outside the casing 10 into the casing 10, and exchange heat via the outdoor heat exchanger 20 to form a heat exchange air flow, and the heat exchange air flow is output to the outside of the casing 10 under the driving of the outdoor fan 30, so that the outdoor fan 30 can accelerate the flow rate of the air flowing through the outdoor heat exchanger 20, thereby improving the heat exchange efficiency of the air conditioner outdoor unit 100 and the working performance of the air conditioner outdoor unit 100.

Specifically, the air conditioner outdoor unit 100 in the present application cooperates with an air conditioner indoor unit, and the air conditioner performs a cooling cycle and a heating cycle by using the compressor 50, the four-way valve 40, the gas-liquid separator 60, the throttling part, the outdoor heat exchanger 20, and the indoor heat exchanger 200.

When the air conditioner outdoor unit 100 operates the refrigeration cycle, the compressor 50 extracts low-temperature steam returned from the gas-liquid separator 60, compresses the low-temperature steam into high-temperature steam, then enters the outdoor heat exchanger 20 through the four-way valve 40, cools the refrigerant into medium-temperature liquid in the outdoor heat exchanger 20, then enters the throttling part, reduces the pressure and temperature through the throttling part, becomes low-temperature low-pressure liquid, then enters the indoor heat exchanger 200, absorbs heat through the indoor heat exchanger 200, evaporates the refrigerant into low-temperature steam, enters the gas-liquid separator 60 through the four-way valve 40, deposits the liquid refrigerant to the bottom of the container in the gas-liquid separator 60, and the gas refrigerant enters the compressor 50 again, thereby completing one refrigeration cycle.

When the air conditioner outdoor unit 100 is operated to perform a heating cycle, the compressor 50 extracts low-temperature steam returned from the gas-liquid separator 60, compresses the low-temperature steam into high-temperature steam, then enters the indoor heat exchanger 200 through the four-way valve 40, cools the refrigerant in the indoor heat exchanger 200 into medium-temperature liquid, then enters the throttling part, reduces the temperature through the pressure reduction of the throttling part, becomes low-temperature low-pressure liquid, then enters the outdoor heat exchanger 20, absorbs heat through the outdoor heat exchanger 20, evaporates the refrigerant into low-temperature steam, enters the gas-liquid separator 60 through the four-way valve 40, deposits the liquid refrigerant in the gas-liquid separator 60 to the bottom of the container, and the gas refrigerant enters the compressor 50 again, thereby completing a refrigerating cycle.

The compressor 50 is responsible for the compression work of the refrigerant, the four-way valve 40 is responsible for the switching of the refrigerating and heating modes, the indoor heat exchanger 200 and the outdoor heat exchanger 20 are responsible for the heat dissipation or heat absorption of the refrigerant, the throttling component is responsible for the temperature reduction and the pressure reduction of the refrigerant, and the gas-liquid separator 60 is responsible for storing redundant refrigerant. Considering that the components are all required to be connected through the pipeline 90, the pipeline 90 is required to meet the requirements of shock absorption and stress, so that more severe requirements are required for arrangement and connection of the components, and the volume of the air conditioner outdoor unit 100 is prevented from being increased on the premise that the air conditioner outdoor unit 100 can normally work.
