[0051] Please refer to Figure 1 , an integrated gas supplement and enthalpy increasing function agent side integrated system, wherein the integrated gas supplement and enthalpy increasing function agent side integrated system comprises:

[0052] A compressor 1, the compressor 1 has oppositely arranged first and second ends, the first end of the compressor 1 is provided with an outer cover 18, and the second end of the compressor 1 is provided with a controller 9;

[0053] A valve island 2 is installed on the top surface of the compressor 1; a water cooler 2, a refrigeration device 3, a liquid storage tank 4, an economizer 5, a first expansion valve 6, and a second expansion valve 7 are fixedly connected to the valve island 8 and installed on the top surface of the compressor 1; wherein the economizer 5 is installed on the first end side of the valve island 8, the economizer 5 is connected to the outer cover 18 of the compressor 1 through a flow guide pipe 55, and the compressor 1 is supplemented with gas.

[0054] Based on the above structure of the present application, each element can be integrated through the valve island 8, and the air supplement can be realized through the end air inlet of the compressor 1, the structure is small in size, and the air supplement channel 181 is short, and specifically, in the structure of the present application, the valve island 8 is fixed on the top of the compressor 1, and the valve island 8 is connected with the corresponding water cooler 2, refrigerant cooler 3, liquid storage tank 4, economizer 5, first expansion valve 6, second expansion valve 7 and other structures, thereby forming a highly integrated refrigerant side integrated system, which is small in size and easy to maintain. Meanwhile, the economizer 5 in the present application is arranged near the end of the compressor 1, and directly supplements the air in the compressor 1 through the end cover 18 of the compressor 1, and the economizer 5 installed on the opposite side of the air supplement flow channel is shorter. The valve island 8 not only plays a role of fixing the above-mentioned water cooler 2, refrigerant cooler 3, liquid storage tank 4, economizer 5, first expansion valve 6, second expansion valve 7 and other elements, but also can be connected with any of the above-mentioned elements, so as to realize the through of the refrigerant according to the corresponding flow line.

[0055] For the air supplement and enthalpy increasing part in the present application, please refer to Figures 1-3 Specifically, during installation, the static disc 14 can be first fixed on the first end side of the cylinder body of the compressor 1, based on the position of the recess 141 on the static disc 14, the fixed end 171 of the valve piece 17 can be first fixed on the second end surface side of the cover plate 16, then the cover plate 16 connected with the valve piece 17 is installed in the recess 141 by aligning the position of the cover plate 16 with the position of the recess 141, and the position of the movable end 172 of the valve piece 17 is aligned with the positions of the recess 141 and the air inlet hole 143, then the connecting plate 151 is installed outside the cover plate 16, and the connecting plate 151 is fixed in the recess 141 through the bolts 152, so that the cover plate 16 is also clamped in the recess 141.

[0056] In the closed state without air intake, the movable end 172 of the valve piece 17 is tightly attached to and covers all the through holes 161 of the cover plate 16, so that the through holes 161 are isolated from the air intake hole 143. At this time, the valve piece 17 blocks the through holes 161, and the refrigerant in the cylinder of the compressor 1 cannot enter the air supplement pipe 15 in the reverse direction, considering that the valve piece 17 can only bend to the side away from the cover plate 16.

[0057] In the air supplement process, the air supplement pipe 15 is in a ventilated state, the valve piece 17 is deformed under the action of air pressure, and the movable end 172 of the valve piece 17 is separated from the cover plate 16 to make the air intake hole 143 and the through hole 161 communicate. Specifically, the air supplement pipe 15 fills the refrigerant gas from the first end side to the second end side, the valve piece 17 can bend to the side away from the cover plate 16, and a space for gas passing between the valve piece 17 and the through hole 161 of the cover plate 16 is formed, so that the refrigerant gas can pass through the through hole 161 of the cover plate 16 and then pass through the static disc 14 through the recess 141 and the air intake hole 143 to enter the side of the compressor 1, thereby achieving air supplement.

[0058] In the above structure, the air supplement and enthalpy increasing device can be arranged at the end of the compressor 1, that is, the side of the static disc 14, so as to significantly reduce the overall volume and facilitate installation. In use, air is directly introduced through the side of the static disc 14 at the end of the compressor 1 for air supplement, compared with installing air supplement and enthalpy increasing elements on the side wall of the compressor 1, the overall volume of the compressor 1 is significantly reduced, the integration is high, and the one-way control of the gas is realized with the cooperation of the cover plate 16 and the valve piece 17 with small axial thickness, the structure is simple and efficient.

[0059] In another embodiment, the outer cover 18 is arranged on the first end of the compressor 1, and the outer cover 18 covers all the static discs 14. The main function of the outer cover 18 is to serve as the main protective cover on the first end side of the compressor 1 to support and protect the internal structure, and the outer cover 18 can be directly locked and connected with the cylinder of the main body of the compressor 1 through peripheral bolts. In this embodiment, the outer cover 18 is provided with an air supplement channel 181, and the second end of the air supplement channel 181 is in communication with the first end of the air supplement pipe 15. The air supplement channel 181 serves as an external interface for air supplement at the end of the first end of the compressor 1 and is directly connected in the direction of the end. Similarly, the outer cover 18 can also be arranged to be directly connected with the water cooler for exchanging refrigerant with the water cooler, and also penetrating the static disc 14 and entering the inside of the compressor 1.

[0060] That is, the air supplement and the refrigerant air intake on the side of the main refrigeration device are arranged on the side of the outer cover 18, and the integration is high.

[0061] In the embodiment, the static disc 14 is provided with a plurality of air inlet holes 143, each of which corresponds to a valve piece 17. The plurality of valve pieces 17 share the same connecting plate 151. The first end surface of the cover plate 16 is provided with a raised isolation portion 162, and the second end surface of the cover plate 16 is in abutment with the isolation portion 162, so that a gap is formed between the second end surface of the cover plate 16 and the through hole 161. Specifically, the above-mentioned air inlet hole 143 and valve piece 17 combination can be provided in two, one of which in the embodiment is directly opposite the air supplement pipe 15, and the refrigerant injected from the second end of the air supplement pipe 15 can directly push away the adjacent valve piece 17 and directly enter the air inlet hole 143 in the groove 141, while another part of the refrigerant injected from the second end of the air supplement pipe 15 can flow to the other air inlet hole 143 position spaced apart through the gap between the isolation portion 162 and the connecting plate 151, and supplement air from the corresponding air inlet hole 143 of the other spaced groove 141.

[0062] The above-mentioned one air supplement pipe 15 can supplement air to a plurality of air inlet holes 143 in different positions, so that the effect of air supplement is more uniform.

[0063] Further, in the above-mentioned embodiment, in the case of only one air inlet hole 143 and a corresponding valve piece 17 combination, the position of the air inlet hole 143 matches the through hole 161, the air inlet path of the air inlet hole 143 is the shortest and the most unobstructed. In the case of multiple sets of air inlet holes 143 and valve pieces 17, at least one set is the case where the position of the air inlet hole 143 matches the through hole 161.

[0064] In the embodiment, the valve piece 17 has a predetermined rigidity, so that in the air passage state, the movable end 172 of the valve piece 17 can always not cover the air inlet hole 143. That is, on the basis of the air inlet and pushing of the valve piece 17 by the second end of the air supplement pipe 15, the bending deformation degree of the valve piece 17 is always controlled by means of the above-mentioned rigidity setting of the valve piece 17, so as to avoid the case that the valve piece 17 blocks the air inlet hole 143 in the corresponding groove 141, resulting in the failure to supplement air to the compressor 1.

[0065] In fact, in the above-mentioned embodiment with a plurality of air inlet holes 143, the grooves 141 where the plurality of air inlet holes 143 are located can connect the air inlet holes 143 in series to form a complete multi-segment or arc-shaped groove 141 shape, and the connecting plate 151 and the cover plate 16 are provided as an arc or multi-segment shape embedded in the groove 141.

[0066] For the design and structure of the valve island 8 in the present application, please refer to Figures 4-10Wherein the valve island 8 itself can be provided as a separate box-shaped block, in the installation, the water cooler 2, the refrigeration device 3, the liquid storage tank 4, the economizer 5, the first expansion valve 6, the second expansion valve 7 and the valve island 8 can be connected in advance, and the valve island 8 is installed on the top surface of the compressor 1, and is fixed by means of bolts, so that the above-mentioned elements and the valve island 8 are fixed on the compressor 1, and then the remaining water cooler 2, the refrigeration device 3, the liquid storage tank 4, the economizer 5, the first expansion valve 6, the second expansion valve 7 and the valve island 8 are fixed on the installed valve island 8, so that all the elements are fixed on the compressor 1 by means of the support of the valve island 8.

[0067] Based on the structure of the present application, the corresponding elements including the economizer 5 can be integrated and incorporated on the compressor 1 by the intervention of the valve island 8, which has high integration degree and is easy to install. Specifically, the valve island 8 itself not only can be used as a flow channel bridge for the serial connection of the compressor 1, the water cooler 2, the refrigeration device 3, the liquid storage tank 4, the economizer 5, the first expansion valve 6 and the second expansion valve 7, but also can be fixed on the top of the compressor 1 body, so that it itself serves as a stable support to fix the water cooler 2, the refrigeration device 3, the liquid storage tank 4, the economizer 5, the first expansion valve 6 and the second expansion valve 7 on the compressor 1 by means of the valve island 8 itself, which has high stability and high integration degree.

[0068] Specifically, in the present application, the compressor 1 has an exhaust port 11, a suction port 12 and a charge port 13, the water cooler 2 includes a water cooling inlet 21 and a water cooling outlet 22, the refrigeration device 3 includes a refrigeration inlet 31 and a refrigeration outlet 32, the liquid storage tank 4 includes a liquid storage inlet 41 and a liquid storage outlet 42, the economizer 5 includes a first inlet 51, a first outlet 52, a second inlet 53 and a second outlet 54, and the valve island 8 forms independent first, second, third, fourth, fifth and sixth channels 81, 82, 83, 84, 85 and 86, wherein,

[0069] Please refer to the perspective view of the economizer 5 of the present application Figure 4 The exhaust port 11 is directly connected with the water cooling inlet 21; the water cooling outlet 22 is directly connected with the liquid storage inlet 41;

[0070] As shown in the channel cross-sectional view of the valve island of the present application Figure 6 The liquid storage outlet 42 is connected with the first inlet 51 through the first channel 81 and is connected to the first outlet 52 through the economizer 5;

[0071] As shown in the channel cross-sectional view of the valve island of the present application Figure 7 The first outlet 52 is connected with the first expansion valve 6 through the second channel 82;

[0076] As shown in the channel cross-section schematic view of the valve island of the present application Figure 4 As shown in the channel cross-section schematic view of the valve island of the present application

[0077] Based on the above structure, when the compressor 1 pressurizes the refrigerant, the refrigerant is directly discharged from the exhaust port 11 into the water cooling inlet 21. The refrigerant and the cooling liquid in the water cooler 2 are coupled and then flow out from the water cooling outlet 22. The refrigerant flows into the liquid storage inlet 41 and then flows out from the liquid storage outlet 42 to the first channel 81. Then, the refrigerant is guided to the first inlet 51 of the economizer 5. After flowing through the economizer 5, the refrigerant flows out from the first outlet 52. One of the refrigerants is guided by the second channel 82 to the first expansion valve 6, and then flows into the refrigeration inlet 31 and the cooling liquid in the refrigeration device 3 after pressure reduction and expansion. The refrigerant flows out from the refrigeration outlet 32. The refrigerant is guided by the fourth channel 84 to return to the compressor from the suction port 12.

[0078] Another refrigerant flowing out from the first outlet 52 of the economizer 5 is guided by the fifth channel 85 to enter the second expansion valve 7. After throttling of the second expansion valve 7, the refrigerant returns to the economizer 5 from the second inlet 53 through the sixth channel 86, and exchanges heat with the refrigerant entering the economizer 5 for the first time. Then, the refrigerant flows out from the second outlet 54 and enters the compressor 1 from the air inlet 13 through the flow guide pipe 55, thereby achieving air supply to the compressor 1.

[0079] In another embodiment, the first inlet 51, the first outlet 52 and the second inlet 53 of the economizer 5 are arranged on the same side of the valve island 8 and are respectively connected with the valve island 8, and the second outlet 54 of the economizer 5 is arranged on the side away from the valve island 8 and is connected with the air supplement port 13 of the compressor 1 through the flow guide pipe 55. That is, the same side of the valve island 8 in the present application simultaneously interfaces with three passages, and the economizer 5 shown in the prior art is arranged on the side away from the outside, and the air supplement is realized through the only flow guide pipe 55, and the external pipeline is only the flow guide pipe 55 itself, and the main pipeline passages are arranged on the inside, and the integration degree is high. Figure 1

[0080] In the present application, the compressor 1 has oppositely arranged first and second ends, the economizer 5 is arranged on the side close to the first end of the compressor 1, the liquid storage tank 4 is arranged on the side close to the second end of the compressor 1, and the valve island 8 is arranged between the first and second ends of the compressor 1. Further, the water cooler 2 and the refrigerant cooler 3 are respectively arranged between the first and second ends of the compressor 1 and are respectively suspended and fixed on the opposite sides of the valve island 8. Further, the first expansion valve 6 and the second expansion valve 7 are installed on the top of the valve island 8. Therefore, based on the valve island 8, an “airplane-shaped” balanced layout is actually formed, the valve island 8 and the compressor 1 serve as the main cabin, the water cooler 2 and the refrigerant cooler 3 serve as the wings on the two sides, the liquid storage tank 4 and the economizer 5 serve as the nose and tail respectively, the weight is balanced, specifically, the compressor 1 has a preset center of mass, and the center of mass of the whole of the water cooler 2, the refrigerant cooler 3, the liquid storage tank 4, the economizer 5, the first expansion valve 6, the second expansion valve 7 and the valve island 8 is close to or located on the vertical plane of the preset center of mass. Through the above-mentioned balanced arrangement of the center of mass, not only the integration degree can be improved, but also the overall structure can have stronger stability during vehicle operation, and the situation that some connection points are subjected to excessive stress and the structure is loose due to long-term deviation of the unbalanced center of mass can be avoided.
