[0036] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0037] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0038] like Figures 1 to 5 As shown, Figure 3 The a direction refers to the length direction of the mounting plate 20, which is also the width direction of the shell 10, and the b direction refers to the height direction of the mounting plate 20, which is also the height direction of the shell 10.

[0039] It is understandable that the first valve assembly can be a control valve 14 of an outdoor unit of a HVAC device, and the control valve 14 is used to control the circulation or closing of the refrigerant in the enthalpy-increasing injection pipe 102 to control the air supply of the compressor 101, and the control valve 14 can also have a flow control function. The control valve 14 can be a solenoid valve, which includes a valve body and a control valve 14 coil sleeved on the valve body. The control valve 14 coil controls the opening or closing of the valve 14 body to control the circulation or closing of the refrigerant in the enthalpy-increasing injection pipe 102. The compressor 101 with the jet enthalpy increasing function has an enthalpy increasing injection pipe 102. The enthalpy increasing effect is achieved by the enthalpy increasing injection pipe 102 in the middle of the two-stage throttling injection technology. The compressor 101 compresses and injects mixed cooling at medium and low pressures, and then compresses normally at high pressures to increase the exhaust volume of the compressor 101, so as to achieve the purpose of improving the heating capacity in a low temperature environment. The refrigerant is supplemented to the air supply port of the intermediate pressure chamber of the compressor 101 through the enthalpy increasing injection pipe 102, thereby increasing the exhaust volume of the compressor 101, so as to increase the refrigerant dosage of the heating cycle refrigeration, thereby increasing the heating capacity of the air conditioner. The second valve assembly can be a high and low pressure stop valve of the air conditioner outdoor unit.

[0040] Specifically, the mounting plate 20 may be a rectangular plate structure, and is made by a sheet metal process according to a sheet metal part, and the first mounting portion 21 may be a bolt hole opened on the mounting plate 20, so as to fix the control valve 14 by bolts. A clamping hole or a notch may also be provided to clamp the valve body of the control valve 14 or the connected pipeline in the clamping hole for fixing. A housing cavity having an outer shape adapted to the control valve 14 may also be defined by bending the sheet metal, and the control valve 14 may be installed in the housing cavity for fixing.

[0044] like Figures 2 to 3 As shown, in some embodiments of the present invention, a convex plate 26 is formed on a portion of the top of the mounting plate 20, and at least one first connection hole 211 is provided on the convex plate 26.

[0046] It is understandable that the first mounting notch 221 can be semicircular for the valve body or pipeline of the high-pressure shut-off valve 12 and the low-pressure shut-off valve 13 to pass through, or can be other shapes that are compatible with the valve body of the high-pressure shut-off valve 12, such as an arc. The second mounting notch 222 can be circular for the valve body or pipeline of the low-pressure shut-off valve 13 to pass through, or can be other shapes that are compatible with the valve body of the low-pressure shut-off valve 13, such as an arc. The first mounting notch 221 and the second mounting notch 222 can be arranged at intervals along the length direction of the mounting plate 20. Bolt holes can also be arranged on the periphery of the first mounting notch 221 and the second mounting notch 222, and the bolt holes can be arranged one on the left and one on the right of the first mounting notch 221 and the second mounting notch 222. Bolts are inserted through the bolt holes and connected to the high-pressure shut-off valve 12 and the low-pressure shut-off valve 13, so as to further enhance the reliability of the connection between the high-pressure shut-off valve 12 and the low-pressure shut-off valve 13 and the valve group fixing component.

[0047] Specifically, along the vertical direction, that is, along the height direction of the shell ( Figure 3 In the middle (b direction), the openings of the first mounting notch 221 and / or the second mounting notch 222 are set downward, so that the valve bodies or pipelines of the high-pressure stop valve 12 and the low-pressure stop valve 13 can be easily connected to the first mounting notch 221 and the second mounting notch 222 from bottom to top, which is convenient for assembly.

[0048] like Figures 2 to 3 As shown, in some embodiments of the utility model, the mounting plate 20 is provided with at least one mounting hole, and the mounting holes include at least one first mounting hole 223 and at least one second mounting hole 224. The first mounting hole 223 is arranged on the periphery of the first mounting notch 221, and the second mounting hole 224 is arranged on the periphery of the second mounting notch 222. A second fastener can be passed through the first mounting hole 223 to fix the high-pressure shut-off valve 12 on the mounting plate 20, and a third fastener can be passed through the second mounting hole 224 to fix the low-pressure shut-off valve 13 on the mounting plate 20.

[0049] It can be understood that at least one first mounting hole 223 and at least one second mounting hole 224 can be respectively set on the periphery of the first mounting notch 221 and the second mounting notch 222. The first mounting hole 223 and the second mounting hole 224 can be used as bolt holes. The bolt holes can be arranged one on the left and one on the right of the first mounting notch 221 and the second mounting notch 222. The second fastener and the third fastener can be used as bolts, which are passed through the bolt holes and connected to the high-pressure shut-off valve 12 and the low-pressure shut-off valve 13 by bolts, so as to further enhance the reliability of the connection between the high-pressure shut-off valve 12 and the low-pressure shut-off valve 13 and the valve group fixing component.

[0050] like Figures 4 to 5As shown, in some embodiments of the present invention, along the thickness direction of the mounting plate 20 , one side of the mounting plate 20 is used to set the high-pressure stop valve 12 and the low-pressure stop valve 13 , and the first mounting portion 21 is set on the other side of the mounting plate 20 .

[0051] It is understandable that the high-pressure stop valve 12 and the low-pressure stop valve 13 are arranged on the outer side of the mounting plate 20, that is, the side of the mounting plate 20 facing the outer side of the outdoor unit 100, to facilitate installation and maintenance. The first mounting portion 21 is arranged on the inner side of the mounting plate 20 to install the one-way control valve 14, and the valve bodies are arranged on both sides of the mounting plate 20 in a reasonable manner, thereby improving the compactness of the structure and facilitating installation and maintenance operations.

[0052] like Figures 2 to 5 As shown, in some embodiments of the utility model, at least one second connecting hole 23 is respectively provided at both ends of the mounting plate 20 along the length direction of the mounting plate 20, and the valve group fixing assembly also includes a fourth fastener, which is passed through the second connecting hole 23 and is used to connect the bracket 15 of the outdoor unit 100.

[0053] It can be understood that the mounting plate 20 is a long strip plate structure, and second connecting holes 23 can be set at both ends of the mounting plate 20. The second connecting holes 23 can be in the form of bolt holes. The fourth fastener can be a bolt structure. The bolts are passed through the second connecting holes 23 and connected to the bracket 15 of the outdoor unit 100 to achieve the fixation of the valve group fixing assembly, thereby making the vibration benchmark of the valve mounting plate and the structure connected thereto consistent with the bracket 15, avoiding pulling damage to the pipeline due to different vibrations, thereby improving the overall reliability of the outdoor unit 100.

[0054] like Figures 2 to 3 As shown, in some embodiments of the present invention, a flange structure 24 is provided at the edge of the mounting plate 20 .

[0055] It is understandable that the flange structure 24 is bent at the edge of the mounting plate 20, that is, the four sides of the mounting plate 20, so that the overall strength of the mounting plate 20 is improved, thereby improving the rigidity of the mounting plate 20 under vibration, thereby improving the overall reliability of the outdoor unit 100.

[0056] like Figures 1 to 5 As shown, the second aspect of the utility model provides an outdoor unit 100 for HVAC equipment, comprising:

[0057] The housing 10 defines a receiving chamber 11;

[0058] A bracket 15 is disposed in the accommodating cavity 11;

[0059] The valve group fixing assembly is the valve group fixing assembly proposed in the first aspect of the utility model, and the valve group fixing assembly is installed on the bracket 15 and is arranged in the accommodating chamber 11;

[0060] A first valve assembly is disposed in the accommodating cavity 11 and mounted on a first mounting portion 21 of the valve assembly fixing assembly;

[0061] The second valve assembly is disposed in the accommodating cavity 11 and is mounted on the second mounting portion 22 of the valve group fixing assembly.

[0062] It is understandable that the HVAC equipment can be an air conditioning system or a heat pump system, the housing 10 is the overall housing of the outdoor unit 100, such as the housing of the air conditioning outdoor unit, the housing 10 defines a housing chamber 11, and the housing chamber 11 accommodates various structural parts of the outdoor unit 100, and the bracket 15 can be the main bracket 15 of the outdoor unit 100, and its function is to support and fix the housing 10, and to fix some pipelines and devices. The bracket 15 can be an H-shaped structure or a door-shaped structure, which is composed of profiles or sheet metal parts. The valve group fixing assembly can be fixed to the bracket 15 by welding or bolts, so that the vibration base of the valve group fixing assembly and each valve installed thereon is unified with the bracket 15, reducing the phenomenon that the pipeline is pulled and damaged due to different vibrations. The valve group fixing assembly is installed on the bracket 15 of the outdoor unit, and can also be fixed on the inner side of the shell 10. The first valve assembly and the second valve assembly are installed in the accommodating cavity 11 through the valve group fixing assembly and are not exposed outside the shell 10, making the exterior of the outdoor unit 100 more concise and beautiful, and the shell 10 can protect the high-pressure stop valve 12 and the low-pressure stop valve 13.

[0063] The outdoor unit 100 proposed in the second aspect of the utility model is fixed by arranging a valve group fixing component in the accommodating cavity 11 formed by the housing 10, and installing the high-pressure stop valve 12 and the low-pressure stop valve 13 on the valve group fixing component. In addition, the high-pressure stop valve 12, the low-pressure stop valve 13 and the valve group fixing component are located in the accommodating cavity 11 and are not exposed outside the housing 10, so that the appearance of the outdoor unit 100 is more concise and beautiful.

[0064] like Figures 1 to 5As shown, the first valve assembly includes a control valve 14, and the second valve assembly is used to control the on and off of the enthalpy-increasing injection pipe 102. The control valve 14 is installed on the valve group fixing assembly and is arranged in the accommodating chamber 11. The second valve assembly includes a high-pressure stop valve 12 and a low-pressure stop valve 13. The high-pressure stop valve 12 and the low-pressure stop valve 13 are both installed on the valve group fixing assembly and are arranged in the accommodating chamber 11. The mounting plate 20 takes into account the installation and fixation of the high-pressure stop valve 12, the low-pressure stop valve 13 and the control valve 14 at the same time, so that the control valve 14 is more stable when vibrating, and the vibration reference is consistent with the rigid structure such as the bracket 15, so as to reduce the pulling of the enthalpy-increasing injection pipe 102 connected to the control valve 14 due to inconsistent vibration.

[0065] like Figures 4 to 5 As shown, in some embodiments of the utility model, the bracket 15 includes a first support member 151 and a second support member 152. The first support member 151 and the second support member 152 are spaced apart along the width direction of the outdoor unit 100, and the mounting plate 20 of the valve group fixing assembly is respectively connected to the first support member 151 and the second support member 152 at both ends along its own length direction.

[0066] It is understandable that the first support member 151 and the second support member 152 can be extended in the vertical direction to form two column structures to fix and support the shell 10 and some compressor 101 pipelines or other devices. The valve group fixing component extends horizontally to form a beam structure between the first support member 151 and the second support member 152. Bolt holes can be set at both ends of the valve group fixing component along its own length direction, and it is fixed to the first support member 151 and the second support member 152 by bolts. The valve group fixing component is fixed by the first support member 151 and the second support member 152, so that the vibration reference of the valve group fixing component and each valve installed thereon is unified with the bracket 15, reducing the phenomenon that the pipeline is pulled and damaged due to different vibrations.

[0067] like Figures 4 to 5 As shown, in some embodiments of the present invention, the bracket 15 is provided with a limiting portion 16 , and the mounting plate 20 of the valve group fixing assembly is provided with a matching portion 25 . The limiting portion 16 is connected to the matching portion 25 and is used to limit the mounting plate 20 .

[0068] It is understandable that the limiting portion 16 can be a limiting hole provided on the bracket 15, and the matching portion 25 can be a protrusion provided on the mounting plate 20. The protrusion is inserted into the limiting hole to limit the mounting plate 20, further improving the reliability of the connection and reducing the shaking of the mounting plate 20 during vibration. The protrusion can be provided at both ends of the mounting plate 20 along its own length direction, and the limiting hole is provided at the corresponding position of the bracket 15. The limiting portion 16 and the matching portion 25 can also be in the form of a card slot and a protrusion, which can also play a role in limiting the mounting plate 20.

[0069] like Figures 4 to 5 As shown, in some embodiments of the present invention, the outdoor unit 100 further includes a chassis 17 , the bracket 15 is mounted on the chassis 17 , and along the height direction of the outdoor unit 100 , the valve group fixing assembly is located above the chassis 17 .

[0070] It is understandable that the chassis 17 can be a water receiving pan of the outdoor unit 100, and its function is to receive condensed water and some leaked water of the outdoor unit 100. The chassis 17 assembly can also fix the pipeline and the device to improve the overall connection reliability. The bottom end of the bracket 15 can be fixed to the chassis 17 by welding or bolts, and the valve group fixing assembly is arranged above the chassis 17 through the bracket 15, so that the valve body on the valve group fixing assembly and the liquid leaked from the pipeline can be received by the water receiving pan, reducing the phenomenon that the circuit part of the outdoor unit 100 is soaked by liquid to cause safety hazards.

[0071] 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 person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
