The various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-described embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0022] like Figure 1 and Figure 2 As shown, in one embodiment, a compressor device 10 is provided, including a compressor 11, wherein an auxiliary shell 12 is disposed outside the shell 111 of the compressor 11, and a gas-liquid separation chamber 13 is formed between the auxiliary shell 12 and the shell 111 of the compressor 11. An air suction port 121 is disposed on the auxiliary shell 12, and an air inlet 122 is disposed on the shell 111 of the compressor 11, and the air inlet 122 is communicated with the air suction chamber of the pump body of the compressor 11. A gas-liquid separation component is disposed in the gas-liquid separation chamber 13, which is used to separate the mixed refrigerant sucked from the air suction port 121 into gas and liquid, and the separated gaseous refrigerant can enter the air suction chamber of the pump body of the compressor 11 from the air inlet 122, and the separated liquid is deposited in the liquid collection chamber 131 of the gas-liquid separation chamber 13.

[0023] The pump body structure of the compressor 11 is arranged in the shell 111 of the compressor 11, and the gas-liquid separation chamber 13 formed between the auxiliary shell 12 and the shell 111 of the compressor 11 provides space for the gas-liquid separation process. The gaseous refrigerant obtained by gas-liquid separation in the gas-liquid separation chamber 13 enters the suction chamber of the pump body of the compressor 11 from the air inlet 122.

[0024] By arranging the auxiliary shell 12 outside the outer shell 111 of the compressor 11, so that the gas-liquid separation chamber 13 surrounds the compressor 11, and the gas-liquid separation component is arranged in the gas-liquid separation chamber 13, the mixed refrigerant entering the air inlet 121 is separated into gas and liquid under the action of the gas-liquid separation component in the gas-liquid separation chamber 13, and the separated gaseous refrigerant enters the air inlet chamber of the pump body of the compressor 11 from the air inlet 122, and the separated liquid refrigerant is deposited in the liquid collection chamber 131. The structure for gas-liquid separation is sleeved outside the outer shell 111 of the compressor 11, so that the overall structure of the compressor device 10 is more balanced, the center of gravity of the compressor device 10 is closer to its geometric center, the vibration of the compressor device 10 during operation is reduced, the noise is reduced, and the use performance is improved. Avoid the situation where the gas-liquid separator is hung on one side of the compressor 11, which causes the compressor 11 to vibrate more and generate more noise during operation.

[0025] Moreover, by arranging the auxiliary housing 12 outside the housing 111 of the compressor 11 to form the gas-liquid separation chamber 13, the noise inside the housing 111 of the compressor 11 is not easily transmitted, thereby further reducing the noise of the compressor device 10. Moreover, the refrigerant that undergoes gas-liquid separation outside the housing 111 of the compressor 11 can also cool the compressor 11, improve the use environment of the compressor 11, and reduce the dependence on the external environment.

[0026] Specifically, the gas-liquid separation component can be an annular filter screen capable of filtering the liquid refrigerant, and Figure 3 and Figure 4 As shown, the cross-section of the filter is a structure that is high in the middle and low on both sides. The gaseous refrigerant can pass through the filter, and the liquid refrigerant is blocked and slides to the lower positions on both sides to the wall of the auxiliary shell 12 or the outer shell 111 of the compressor 11, and flows downward along the wall; or the gas-liquid separation component is a gas-liquid separation guide plate spirally arranged in the gas-liquid separation chamber 13, and the mixed refrigerant entering the gas-liquid separation chamber 13 spirally moves forward under the action of the gas-liquid separation guide plate, and the liquid and gas are separated in the process of moving forward.

[0027] Furthermore, in one embodiment, the outer ring of the gas-liquid separation guide plate is connected to the auxiliary shell 12, the inner ring of the gas-liquid separation guide plate is spaced apart from the outer shell 111 of the compressor 11, and a plurality of liquid guide holes are provided on the gas-liquid separation guide plate, and the liquid guide holes pass through the upper surface and the lower surface of the gas-liquid separation guide plate.

[0028] The liquid refrigerant obtained by gas-liquid separation flows downward from the liquid guide holes on the gas-liquid separation guide plate and is deposited in the liquid collecting chamber 131, while the gaseous refrigerant flows through the gap between the gas-liquid separation guide plate and the outer shell 111 of the compressor 11, and finally enters the suction chamber of the pump body from the air inlet 122 on the outer shell 111 of the compressor 11.

[0029] More specifically, if Figure 1 As shown, in one embodiment, the air suction port 121 is located at the top of the auxiliary shell 12, the air inlet 122 is spaced apart from the bottom of the auxiliary shell 12, and the portion of the gas-liquid separation chamber 13 below the air inlet 122 is the liquid collection chamber 131. The liquid refrigerant sliding down the wall is deposited in the liquid collection chamber 131.

[0030] The liquid refrigerant after gas-liquid separation in the gas-liquid separation chamber 13 is deposited in the liquid collection chamber 131, and the separated gaseous refrigerant enters the suction chamber of the pump body from the air inlet 122. The top of the auxiliary housing 12 can be as follows: Figure 1 The highest point of the auxiliary housing 12 shown can also be Figure 2 The upper part of the auxiliary shell 12 is shown. The positions of the air intake port 121 and the air inlet port 122 are mainly to ensure that the mixed refrigerant entering from the air intake port 121 can be fully separated into gas and liquid under the action of the gas-liquid separation component. The air inlet port 122 is spaced apart from the bottom end of the auxiliary shell 12 to provide sufficient sedimentation space for the liquid refrigerant.

[0031] Further, in one embodiment, if Figure 3 As shown, the filter is a first gas-liquid filter 15, the inner circle of the first gas-liquid filter 15 is connected to the outer shell 111 of the compressor 11, and the outer circle of the first gas-liquid filter 15 is connected to the auxiliary shell 12. The compressor equipment 10 also includes a gas duct 16, one end of the gas duct 16 is connected to the air inlet 122, and the other end of the gas duct 16 extends upward to a position close to the first gas-liquid filter 15.

[0032] After being filtered by the first gas-liquid filter 15 , the gaseous refrigerant enters the air inlet 122 through the gas conduit 16 . The gas conduit 16 extends to a position close to the first gas-liquid filter 15 , effectively preventing the liquid refrigerant sliding along the wall from entering the air inlet 122 .

[0033] Further, in one embodiment, if Figure 2 As shown, the air intake port 121 is located on the side wall of the auxiliary shell 12 , and the air intake port 121 is provided with an air intake pipeline (not shown in the figure), and the air intake pipeline is tangent to the outer side surface of the auxiliary shell 12 .

[0034] In this way, the mixed refrigerant entering the gas-liquid separation chamber 13 from the air intake port 121 can spirally descend along the inner wall of the auxiliary shell 12, extending the distance of gas-liquid separation, thereby improving the effect of gas-liquid separation.

[0035] Furthermore, if the gas-liquid separation component includes a spirally arranged gas-liquid separation guide plate, the mixed refrigerant entering from the air intake port 121 can move along the gas-liquid separation guide plate better, thereby improving the gas-liquid separation effect.

[0036] Further, in one embodiment, if Figure 2 As shown, an isolation layer 14 is provided between the auxiliary shell 12 and the outer shell 111 of the compressor 11. The isolation layer 14 is spaced between the auxiliary shell 12 and the outer shell 111 of the compressor 11. The bottom end of the isolation layer 14 extends to below the air inlet 122 and is connected to the auxiliary shell 12 or the outer shell 111 of the compressor 11. The top end of the isolation layer 14 is spaced from the top end of the auxiliary shell 12, and the air intake port 121 is provided on the side wall of the auxiliary shell 12.

[0037] Therefore, the mixed refrigerant entering from the air inlet 121 is separated into gas and liquid in the gap formed between the isolation layer 14 and the auxiliary shell 12, and the separated gaseous refrigerant enters the gap formed between the isolation layer 14 and the shell 111 of the compressor 11 from the top of the isolation layer 14, and finally enters the suction cavity of the pump body from the air inlet 122 on the shell 111 of the compressor 11. The gas-liquid separation process is effectively isolated outside the isolation layer 14, and the liquid refrigerant is deposited in the gap formed between the isolation layer 14 and the auxiliary shell 12.

[0038] In one embodiment, if the gas-liquid separation component includes a spirally arranged gas-liquid separation guide plate, the gas-liquid separation guide plate is sleeved in the gap between the isolation layer 14 and the auxiliary shell 12. At this time, the outer circle of the gas-liquid separation guide plate is connected to the auxiliary shell 12, and the inner circle of the gas-liquid separation plate is spaced from the isolation layer 14, providing a circulation space for the gaseous refrigerant.

[0039] Further, in one embodiment, if Figure 2 As shown, the gas-liquid separation component includes an annular second gas-liquid filter 17, the second gas-liquid filter 17 is located between the isolation layer 14 and the outer shell 111 of the compressor 11, the second gas-liquid filter 17 is located above the air inlet 122, the inner circle of the second gas-liquid filter 17 is connected to the outer shell 111 of the compressor 11, and the outer circle of the second gas-liquid filter 17 is connected to the isolation layer 14.

[0040] The second gas-liquid filter 17 further filters the refrigerant flowing into the gap between the isolation layer 14 and the compressor 11 shell 111 , so that only the gaseous refrigerant can continue to move downward and eventually enter the suction chamber of the pump body from the air inlet 122 .

[0041] Further specifically, in one embodiment, Figure 4 As shown, the filter screens are annular third gas-liquid filter screens 18 and fourth gas-liquid filter screens 19, and the third gas-liquid filter screens 18 and the fourth gas-liquid filter screens 19 are spaced apart in the axial direction of the outer shell 111 of the compressor 11, and the third gas-liquid filter screen 18 is located above the fourth gas-liquid filter screen 19, and the fourth gas-liquid filter screen 19 is located above the air inlet 122, and the inner ring of the third gas-liquid filter screen 18 and the inner ring of the fourth gas-liquid filter screen 19 are both connected to the outer shell 111 of the compressor 11, and the outer ring of the third gas-liquid filter screen 18 and the outer ring of the fourth gas-liquid filter screen 19 are both connected to the auxiliary shell 12.

[0042] After multiple filtrations by the third filter screen 18 and the fourth filter screen 19 , the liquid refrigerant slides along the wall surface to the liquid collecting chamber 131 , and the gaseous refrigerant enters the suction chamber of the pump body of the compressor 11 from the air inlet 122 .

[0043] Furthermore, in another embodiment, a refrigeration system is provided, comprising the compressor device 10 in any of the above embodiments. Based on the compressor device 10, a structure for performing gas-liquid separation is sleeved outside the shell 111 of the compressor 11, so that the center of gravity of the compressor device 10 is closer to the geometric center, so that the vibration of the compressor device 10 is smaller during operation, thereby reducing the noise of the refrigeration system and improving the performance.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
