[0038] like Figures 1 to 6 As shown, Figure 5 A in the middle represents the axial direction of the jet reheat compressor. The first aspect of the utility model proposes a compressor assembly, which includes a jet reheat compressor 10 and a jet pipe assembly 20. The jet reheat compressor 10 has a jet port 11. Both ends of the jet pipe assembly 20 are respectively connected to the heat exchanger and the jet port 11. At least part of the pipe section of the jet pipe assembly 20 is arranged on the periphery of the jet reheat compressor 10 and around the jet reheat compressor 10. An installation gap 101 for installing a sound insulation component 14 is formed between the jet pipe assembly 20 and the outer peripheral side of the jet reheat compressor 10.
[0039] It is understandable that the working principle of the jet reheat compressor 10 is a prior art and will not be described in detail here. The jet reheat compressor 10 has a jet port 11 for air replenishment, and the jet pipe assembly 20 is composed of a plurality of pipe sections connected together. One end of the jet pipe assembly 20 can be connected to the jet port 11 by welding. When the jet reheat compressor 10 needs to replenish air, the injection valve body opens, and the medium-pressure refrigerant gas in the refrigeration flow path enters the pressure chamber of the jet reheat compressor 10 from the jet port 11 through the jet pipe assembly 20, and is mixed with the refrigerant in the pressure chamber that has been compressed by the return air, and is compressed again, so that the compressor generates more high-temperature, high-pressure refrigerant to enter the condenser, which improves the heating effect of the HVAC equipment 100 of the air conditioner in a low-temperature environment. Specifically, the jet pipe assembly 20 of the utility model extends as a whole along the circumference of the jet enthalpy increasing compressor 10, and has a plurality of U-shaped pipe sections, so that the bending direction of the jet pipe assembly 20 is increased, thereby improving the flexibility of the jet pipe assembly 20. When the jet enthalpy increasing compressor 10 is running, the jet pipe assembly 20 with multiple bending positions can reduce vibration, thereby reducing the noise generated. Since the jet pipe assembly 20 extends along the circumference of the jet enthalpy increasing compressor 10, and there is an installation gap 101 between the jet enthalpy increasing compressor 10, the sound insulation member 14 can be conveniently installed on the outer peripheral wall of the jet enthalpy increasing compressor 10. The sound insulation member can be sound insulation cotton. Wrapping multiple pieces of sound insulation cotton on the outer peripheral wall of the jet enthalpy increasing compressor 10 improves the sound insulation effect of the jet enthalpy increasing compressor 10, thereby reducing noise and improving user experience.
[0040] In some embodiments of the present invention, the injection pipe assembly 20 includes a plurality of first straight pipe segments 21 and a plurality of first bent pipe segments 22, the plurality of first straight pipe segments 21 and the plurality of first bent pipe segments 22 are alternately arranged, and two adjacent first straight pipe segments 21 are connected by a first bent pipe segment 22, and the first straight pipe segment 21 extends along the axial direction of the jet reheat compressor 10.
[0041] It can be understood that the first straight pipe section 21 is a straight pipe structure, and the axis of the first straight pipe section 21 is arranged parallel to the axial direction of the jet enthalpy increasing compressor 10. A plurality of first straight pipe sections 21 arranged at intervals can be arranged on the periphery of the jet enthalpy increasing compressor 10, and adjacent first straight pipe sections 21 are connected by first bent pipe sections 22. The first bent pipe section 22 can be a U-shaped structure in which two elbow pipes are connected at both ends of a straight pipe. The end of the elbow pipe away from the straight pipe is connected to one end of the first injection pipe. By setting the injection pipe assembly 20 as a pipeline including a plurality of bent pipe sections, the flexibility of the injection pipe assembly 20 is improved, thereby reducing noise when the injection pipe assembly 20 vibrates.
[0042] In some embodiments of the present invention, the jet reheat compressor 10 also has a return air port 12, and the compressor assembly also includes a return air pipe assembly 30, one end of the return air pipe assembly 30 is connected to the return air port 12, and at least part of the return air pipe assembly 30 is arranged on the periphery of the jet reheat compressor 10 and is arranged around the jet reheat compressor 10.
[0043] It can be understood that when the jet reheat compressor 10 is in operation, the refrigerant coming out of the refrigerant outlet of the gas-liquid separator enters the return air pipe, and the refrigerant is transported into the jet reheat compressor 10 to compress the refrigerant respectively.
[0044] The return air pipe assembly 30 is composed of a plurality of pipe sections connected together. One end of the return air pipe assembly 30 can be connected to the return air port 12 by welding. The refrigerant gas in the refrigeration flow path enters the pressure chamber of the jet reheat compressor 10 from the return air port 12 through the return air pipe assembly 30, and is mixed with the refrigerant of the jet pipe assembly 20 in the pressure chamber, and is compressed again, so that the compressor generates a larger flow of high-temperature, high-pressure refrigerant to enter the condenser, thereby improving the heating effect of the HVAC equipment 100 of the air conditioner in a low-temperature environment. Specifically, the return air pipe assembly 30 of the utility model extends as a whole along the circumference of the jet reheat compressor 10, and has a plurality of U-shaped pipe sections, so that the bending direction of the return air pipe assembly 30 is increased, thereby improving the flexibility of the return air pipe assembly 30. When the jet reheat compressor 10 is running, the return air pipe assembly 30 with multiple bends can reduce vibration, thereby reducing the noise generated.
[0045] In addition, the jet enthalpy increasing compressor 10 is also provided with an exhaust port 13 for connecting with an exhaust pipe. The gas-liquid separator is provided with a refrigerant inlet for inputting refrigerant into the gas-liquid separator.
[0046] In some embodiments of the present invention, the return air pipe assembly 30 includes a plurality of second straight pipe sections 31 and a plurality of second bent pipe sections 32, the plurality of second straight pipe sections 31 and the plurality of second bent pipe sections 32 are alternately arranged, and two adjacent second straight pipe sections 31 are connected by a second bent pipe section 32, and the second straight pipe section 31 extends along the axial direction of the jet enthalpy increasing compressor 10.
[0047] It can be understood that the second straight pipe section 31 is a straight pipe structure, and the axis of the second straight pipe section 31 is arranged parallel to the axial direction of the jet enthalpy increasing compressor 10. A plurality of second straight pipe sections 31 arranged at intervals can be arranged on the periphery of the jet enthalpy increasing compressor 10, and adjacent second straight pipe sections 31 are connected by second bent pipe sections 32. The second bent pipe section 32 can be a U-shaped structure in which two elbow pipes are connected at both ends of a straight pipe. The end of the elbow pipe away from the straight pipe is connected to one end of the first return air pipe. By setting the return air pipe assembly 30 as a pipeline containing a plurality of bent pipe sections, the flexibility of the return air pipe assembly 30 is improved, thereby reducing noise when the return air pipe assembly 30 vibrates.
[0048] In some embodiments of the present invention, along the direction from the axis of the jet regenerative braking compressor 10 to the jet port 11 , at least part of the jet pipe assembly 20 and at least part of the return pipe assembly 30 are located on the same side of the jet regenerative braking compressor 10 .
[0049] It can be understood that at least part of the pipe section of the injection pipe assembly 20 extends around the jet reheat compressor 10 and extends a certain angle in the circumferential direction of the jet reheat compressor 10, and at least part of the pipe section of the return pipe assembly 30 extends around the jet reheat compressor 10 and extends a certain angle in the circumferential direction of the jet reheat compressor 10, for example, extending 90° around the jet reheat compressor 10, so that the injection pipe assembly 20 and the return pipe assembly 30 are more curved, thereby improving the flexibility of the pipeline and reducing the pipeline vibration.
[0050] In some embodiments of the present invention, the compressor assembly further includes at least one fixing member 40, and the at least one fixing member 40 is used to connect the adjacent injection pipe assembly 20 and the return pipe assembly 30. The fixing member 40 may be a sheet-type structure, and the material of the fixing member 40 may be an elastic material, such as rubber, and a notch or perforation is provided on the fixing member to fix the injection pipe assembly 20 and the return pipe assembly 30 to reduce vibration and noise.
[0051] Specifically, the fixing member 40 is provided with a first notch 41 and a second notch 42 , a portion of the injection pipe assembly 20 is passed through the first notch 41 and connected to the fixing member 40 , and a portion of the return air pipe assembly 30 is passed through the second notch 42 and connected to the fixing member 40 .
[0052] It is understandable that the fixing member 40 may be a rubber pad or a plastic pad, etc. The fixing member 40 is in a plate shape as a whole and has a first notch 41 and a second notch 42. The first notch 41 is adapted to the injection pipe assembly 20, and the second notch 42 is adapted to the return pipe assembly 30. The fixing member 40 can be clamped with the injection pipe assembly 20 and the return pipe assembly 30 at the same time, thereby fixing the injection pipe assembly 20 and the return pipe assembly 30 to reduce the vibration of the pipeline and improve the user experience.
[0053] In some embodiments of the present invention, at least one first straight pipe section 21 is fixed to the second straight pipe section 31 via a fixing member 40 .
[0054] It can be understood that, for example, the first straight pipe section 21 extending in the height direction of the jet enthalpy increasing compressor 10 is fixed to the second straight pipe section 31 also extending in the height direction of the jet enthalpy increasing compressor 10 through the fixing member 40, and this part of the first straight pipe section 21 can be arranged close to the second straight pipe section 31, so that the length of the fixing member 40 meets the fixing requirements. The first straight pipe section 21 and the second straight pipe section 31 are fixed by the fixing member 40 of elastic material, such as a rubber structure, so that the gap between the two pipe sections can be controlled, so that the layout of the whole machine is more compact, and the vibration of the pipeline is reduced, thereby improving the user experience.
[0055] In some embodiments of the present invention, the fixing member 40 is a rubber member or a silicone member.
[0056] It is understandable that the fixing member 40 can be a rubber structure or a silicone structure as a whole, and it is an integrally formed structure, so that when the fixing member 40 is connected to the injection pipe assembly 20 and the return air pipe assembly 30, the friction and elastic force of the rubber structure make the connection more secure, and the rubber structure can absorb the vibration of the injection pipe assembly 20 and the return air pipe assembly 30, thereby reducing noise. The fixing member 40 can also be partially set as a rubber structure, for example, the part of the fixing member 40 located around the injection pipe assembly 20 and the part around the return air pipe assembly 30 are rigid structures, and the above two parts are connected by the rubber structure, which can also achieve the effect of absorbing vibration.
[0057] In some embodiments of the present invention, the compressor assembly also includes a sound insulation cover, which is located on the outside of the sound insulation member 14. The sound insulation cover defines a accommodating cavity, and the jet reheat compressor 10, at least part of the injection pipe assembly 20, and at least part of the return air pipe assembly 30 are arranged in the accommodating cavity.
[0058] It can be understood that the bends of the injection pipe assembly 20 and the return air pipe assembly 30 that partially surround the jet reheat compressor 10 leave space on its periphery for placing a sound insulation cover. The sound insulation cover can refer to the existing sound insulation cover structure, such as a blanket-type structure made of sound-absorbing material, to wrap around the outer side of the portion of the injection pipe assembly 20 and the portion of the return air pipe assembly 30 that surrounds the jet reheat compressor 10. The sound insulation cover can be annular or U-shaped and surround its outer circumference. By arranging sound insulation parts and sound insulation on both sides of the sound insulation cover, the vibration noise of the jet reheat compressor 10 can be reduced, thereby improving the user experience.
[0059] In some embodiments of the present invention, the compressor assembly further includes a liquid storage tank, which is disposed on the return air pipe assembly 30 and is used to store the refrigerant used by the jet enthalpy increasing compressor 10. The refrigerant is replenished when needed by providing a liquid storage pipe, thereby improving the reliability of the whole machine operation.
[0060] The second aspect of the present invention provides a HVAC device 100 having the compressor assembly provided in the first aspect of the present invention.
[0061] The HVAC device 100 proposed in the second aspect of the present invention has the same beneficial effects as the compressor assembly proposed in the first aspect of the present invention. Specifically, the HVAC device 100 may be an air conditioner outdoor unit, and the compressor assembly is arranged inside the housing of the air conditioner outdoor unit as the core refrigeration assembly of the air conditioner outdoor unit. For the connection relationship and operation principle between the jet enthalpy increase compressor and other components of the air conditioner outdoor unit, please refer to the existing air conditioner outdoor unit equipped with a jet enthalpy increase compressor.
[0062] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
