Of course, the present utility model is not limited thereto, and the introduction pipe 313 of the first separator 310 may be provided as an introduction straight pipe, the connection pipe 330 may be provided as a connection bent pipe, or the introduction pipe 313 of the first separator 310 may be provided as an introduction bent pipe, and the connection pipe 330 may be provided as a connection straight pipe. Under the condition of ensuring the gas-liquid separation effect, the arrangement mode of the ingress pipe 313 and the connection pipe 330 can be adjusted according to the requirement so as to improve the applicability of the structural arrangement of the gas-liquid separator.

In some embodiments, the connection tube 330 has a protrusion height a from the top end of the second separation port 312 to the bottom end of the first separator 310, a protrusion height C from the delivery tube 323 to the bottom end of the second separator 320, and a protrusion height D from the top end of the fourth separation port 322 to the bottom end of the second separator 320, and the relationship: a > B and C > D. It will be appreciated that by having the height of the protrusion of the connecting tube 330 within the first separator 310 greater than the height of the top end of the second separation port 312 from the bottom end of the first separator 310, the gaseous refrigerant and the liquid refrigerant resulting from the gas-liquid separation of the refrigerant within the first separator 310 are relatively lighter, and are adapted to be formed relatively higher in the first separator 310, while the liquid refrigerant is relatively heavier, and are adapted to be formed relatively lower in the second separator. Therefore, by making the protrusion height of the connection pipe 330 in the first separator 310 greater than the height of the top end of the second separation port 312 from the bottom end of the first separator 310, the gaseous refrigerant can be adapted to enter the second separator 320 through the connection pipe 330, while the liquid refrigerant can be adapted to be discharged through the second separation port 312 and into the second heat exchanger 400 for subsequent use. Moreover, the height of the protrusion of the connecting pipe 330 in the second separator 320 is greater than the height of the fourth separating opening 322 from the bottom end of the second separator 320, so that the refrigerant in the second separator 320 is suitable for gas-liquid separation, so that the gaseous refrigerant is suitable for being led into the compressor 100 through the delivery pipe 323, and the separated liquid refrigerant is suitable for being led into the second heat exchanger 400 through the fourth separating opening 322, so that the refrigerant entering the second heat exchanger 400 is purer, and the service performance of the air conditioner 10 is improved.

In some embodiments, the top end of the second separating opening 312 is located at the same height from the bottom end of the first separator 310 as the top end of the fourth separating opening 322 is located at the same height from the bottom end of the second separator 320, so that the purity of the liquid refrigerant separated by the first separator 310 is the same as that of the liquid refrigerant separated by the second separator 320, and the refrigerant flowing in the second heat exchanger 400 has higher heat exchange capability. Moreover, the height of the protrusion of the connecting pipe 330 in the first separator 310 is the same as the height of the protrusion of the delivery pipe 323 in the second separator 320, so as to simplify the structural design of the gas-liquid separator 300 and improve the consistency.

In some embodiments, the gas-liquid separator 300 further comprises: the three-way pipe 340 is provided with a first interface 341, a second interface 342 and a third interface 343, wherein the first interface 341 is used for being communicated with the second separation port 312, the second interface 342 is used for being communicated with the fourth separation port 322, and the third interface 343 is communicated with the sixth connection port 303. In this way, by providing the tee 340, the first port 341 of the tee 340 is adapted to communicate with the second separating port 312, and the second port 342 is adapted to communicate with the fourth separating port 322, so that the liquid refrigerant separated by the first separator 310 and the second separator 320 is adapted to merge into one place and be introduced into the second heat exchanger 400 through the third port 343, so that a sufficient amount of refrigerant is adapted to be collected in the second heat exchanger 400 for circulation, thereby improving the operation performance of the air conditioner 10. Meanwhile, the liquid refrigerant separated by the first separator 310 and the second separator 320 is collected and uniformly introduced into the second heat exchanger 400 through the tee 340, so that the liquid refrigerant is suitable for being mixed in the tee 340, and enough refrigerant is introduced into the second heat exchanger 400 for circulation, thereby improving the service performance of the air conditioner 10.

In some embodiments, the first separator 310 is on the top side of the second separator 320, and/or; the volume of the first separator 310 is greater than the volume of the second separator 320.

In this way, the first separator 310 is disposed on the top side of the second separator 320, so that the gaseous refrigerant separated from the first separator 310 can more reliably enter the second separator 320, so as to enhance the gas-liquid separation effect of the gas-liquid separator 300. In some embodiments, the volume of the second separator 320 may be smaller than the volume of the first separator 310, and the refrigerant is suitable for being mainly separated in the first separator 310, and the separated gaseous refrigerant is suitable for being introduced into the second separator 320 for separation, so that the volume of the second separator 320 is smaller than the volume of the first separator 310, which not only can fit the design of the gas-liquid separator 300, but also can reduce the volume of the gas-liquid separator 300, thereby realizing the miniaturization design of the air conditioner 10 and enabling the structure of the air conditioner 10 to be more compact.
