After the evaporation side fan 42 is started, the air outside the housing 1 can continuously flow into the second chamber 102 from the evaporation side air inlet 1202, and then flows into the channel of the evaporator 32 from the second chamber 102, the air in the channel exchanges heat with the refrigerant in the evaporator 32 and then is cooled to form cold air, and the cold air is pumped to the evaporation side air inlet 1204 through the evaporation side fan 42 after leaving the channel of the evaporator 32, and then is conveyed to the indoor through the air supply pipe.

Referring to fig. 1, the air conditioner 100 further includes a plurality of sections of pipes 5, in an embodiment of the present invention, the pipes 5 include a first pipe 51, a second pipe 52 and a third pipe 53, the first pipe 51 is connected between the compressor 2 and the condenser 31, the second pipe 52 passes through the first partition 13 and is connected between the condenser 31 and the throttling element 523, and the third pipe 53 passes through the first partition 13 and is connected between the evaporator 32 and the compressor 2. In the present embodiment, since the throttling element 523 is a capillary tube with a diameter smaller than that of the pipeline 5, a dry filter 524 is further disposed between the second pipeline 52 and the throttling element 523. In other embodiments, throttling element 523 may also be a thermal expansion valve.

Referring to fig. 4 and 5, in the present embodiment, the second pipeline 52 is a U-shaped pipeline including a first section 525, a second section 526, and a third section 527. In this embodiment, the first section 525 and the third section 527 are located on different sides in the thickness direction of the first separator 13 and extend in parallel, and the second section 526 is connected between the first section 525 and the third section 527 and extends perpendicular to the first separator 13. That is, the end of the third section 527 of the second pipeline 52 is connected to the throttling element 523 in the form of a capillary tube via the dry filter 524. After impurities are filtered by the drying filter 524, the high-pressure refrigerant in the condenser 31 passes through the throttling element 523, so that the blockage caused by the precipitation of the impurities at the throttling element 523 is avoided, the throttling element 523 reduces the pressure of the refrigerant while cooling the refrigerant, the refrigerant entering the evaporator 32 is rapidly cooled, and the effect of refrigerating hot air can be achieved by heat exchange with the hot air. In the present embodiment, the throttling element 523 in the form of a capillary tube is also connected to the evaporator 32 via another line (not numbered), so that communication is achieved between the condenser 31 and the evaporator 32 via the line 5.

Therefore, the U-shaped design gains the overall size optimization based on the small sacrifice of the length reduction scheme for the second pipeline 52, and it can also be understood that the U-shaped design is a proper reduction of the length of the second pipeline 52, not a maximum reduction.
