The pressure reducer can be an expansion valve or a capillary tube.

Specifically, an outdoor air passage is formed in the first housing 11, and an outdoor air inlet and an outdoor air outlet are formed in the first housing 11, that is, the surfaces of the first housing 11 are disposed at the outdoor air inlet and the outdoor air outlet. The outdoor air outlet is located at one side of the first housing 11 facing the outside, so that the outdoor air enters the first housing 11 from the outdoor air inlet and then enters the outside from the outdoor air outlet.

The indoor unit is located at the indoor side, and the indoor unit includes a second casing 12, and an indoor fan and an indoor heat exchanger provided in the second casing 12. An indoor air passage is formed in the second housing 12, and an indoor air inlet and an indoor air outlet are formed in the second housing 12, that is, the surfaces of the second housing 12 are disposed at the indoor air inlet and the indoor air outlet. The indoor air outlet is positioned at one side of the second housing 12 facing the indoor direction, so that indoor air enters the second housing 12 from the indoor air inlet and then enters the indoor from the indoor air outlet.

It will be appreciated that the first housing 11 is disposed outdoors, that is, the first housing 11 is provided with an outdoor air inlet and an outdoor air outlet, and outdoor air enters the first housing 11 from the outdoor air inlet and then enters the outdoor from the outdoor air outlet. The outdoor air passage is provided in the first housing 11, and the compressor, the outdoor heat exchanger 14 and the outdoor fan are all provided in the first housing 11, and outdoor air enters the first housing 11 from the outdoor air inlet and is discharged from the outdoor air outlet after heat exchange is performed in the first housing 11.

The second housing 12 is disposed in a room, and the first housing 11 and the second housing 12 are connected, that is, an indoor air inlet and an indoor air outlet are disposed on the second housing 12, and indoor air enters the second housing 12 from the indoor air inlet and then enters the room from the indoor air outlet. The indoor heat exchanger and the indoor fan are located in the second housing 12, and the indoor air passage is also located in the second housing 12, and the indoor air enters the second housing 12, and enters the room from the indoor air outlet after exchanging heat at the indoor heat exchanger.

Since the first housing 11 is disposed outdoors and the second housing 12 is disposed indoors, the first housing 11 and the second housing 12 are disposed at a distance, a window is spaced between the first housing 11 and the second housing 12, and the second housing 12 is connected to the first housing 11 through the window.

The compressor is arranged in the outdoor air channel, and is provided with an exhaust port and a return port, and the compressor compresses the refrigerant to change the low-pressure refrigerant into a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor from the air return port, the compressor compresses the low-pressure refrigerant into a high-pressure refrigerant, the high-pressure refrigerant is discharged from the exhaust port, the refrigerant releases heat at the condenser, absorbs heat at the evaporator after decompression, and finally enters the compressor from the air return port.

The outdoor heat exchanger 14 is disposed in the outdoor air passage, and exchanges heat between the outdoor air and the refrigerant transferred through the outdoor heat exchanger 14. The outdoor air introduced into the first casing 11 from the outdoor air inlet circulates through the outdoor air passage to the outdoor heat exchanger 14 to exchange heat with the refrigerant.

For example, the outdoor heat exchanger 14 operates as a condenser in the cooling mode of the window air conditioner 100 such that the refrigerant compressed by the compressor is condensed by radiating heat to the outdoor air through the outdoor heat exchanger 14. The outdoor heat exchanger 14 operates as an evaporator in the heating mode of the window air conditioner 100 such that the decompressed refrigerant evaporates by absorbing heat of the outdoor air by the outdoor heat exchanger 14.

Indoor air entering the second housing 12 from the indoor air inlet circulates in the indoor air passage to the indoor heat exchanger to exchange heat with the refrigerant.

Indoor air enters the second housing 12 from the indoor air inlet, circulates in the indoor air channel and flows to the indoor heat exchanger; the refrigerant circulates in the indoor heat exchanger, and when the indoor air passes through the indoor heat exchanger, the indoor air exchanges heat with the refrigerant; the indoor air after heat exchange flows to the indoor air outlet through the indoor air channel, and is discharged to the indoor from the indoor air outlet.

For example, the indoor heat exchanger operates as an evaporator in the cooling mode of the window air conditioner 100 such that the decompressed refrigerant evaporates by absorbing heat of indoor air by the indoor heat exchanger. The indoor heat exchanger operates as a condenser in a heating mode of the window air conditioner 100 such that the refrigerant compressed by the compressor radiates heat to indoor air through the indoor heat exchanger to be condensed.

When the window air conditioner 100 is used for refrigerating, the exhaust port of the compressor is communicated with the outdoor heat exchanger 14, the indoor heat exchanger is an evaporator, the refrigerant releases heat at the outdoor heat exchanger 14 and flows to the indoor heat exchanger, the indoor air entering from the indoor air inlet flows to the indoor heat exchanger, and the refrigerant at the indoor heat exchanger absorbs the heat of the indoor air, so that the indoor refrigerating effect is achieved.
