[0002] Currently, electrical control boxes in HVAC equipment are usually located in the space on the outdoor unit side, so that they can be cooled by the fans on the outdoor unit side to meet the heat dissipation requirements of the electrical control box during the operation of the HVAC equipment. However, the fans on the outdoor unit side need to be constructed as high-power fans (such as high static pressure fans), which results in high cost of the fans on the outdoor unit side. If the fans on the outdoor unit side cannot meet the heat dissipation requirements, there is a risk that the electrical control box will fail due to excessive temperature.

[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0035] The following is for reference. Figures 1-6 HVAC equipment 100 according to an embodiment of this application is described.
[0036] The HVAC equipment 100 can be configured as a rooftop unit, which is an integrated indoor and outdoor unit that features a compact structure and can be directly installed on the roof to save floor space. This application describes the HVAC equipment 100 as a rooftop unit as an example.
[0037] According to an embodiment of this application, the heating and ventilation equipment 100 includes a housing assembly 1 and an electrical control box 2. The housing assembly 1 is the mounting carrier for devices (such as compressors, fans 3, heat exchangers, and electrical control boxes 2) in the heating and ventilation equipment 100.
[0038] The shell assembly 1 includes a central partition 11 and an air duct enclosure 12.
[0039] Combination Figure 1 and Figure 2 As shown, the partition plate 11 is arranged vertically, and a mounting base 111 is provided on the partition plate 11. The duct enclosure 12 is arranged horizontally on one side of the partition plate 11. The duct enclosure 12 can be used to enclose and define the duct in the housing, and can also be used to install and cooperate with the fan 3.
[0040] It is understandable that, since the partition 11 in the housing is arranged vertically, it can be used to divide the housing into two arrangement spaces (e.g., the indoor unit side arrangement space and the outdoor unit side arrangement space of the roof unit), and the air duct enclosure 12 is arranged in one of the arrangement spaces (e.g., the indoor unit side arrangement space).
[0041] Furthermore, the electrical control box 2 is positioned above the duct enclosure 12. The upper end of the electrical control box 2 is provided with a first mounting part 21 for connecting and cooperating with the mounting base 111, and the lower end of the electrical control box 2 is provided with a second mounting part 22. The second mounting part 22 is used to connect and fix with the duct enclosure 12, so as to install and fix the electrical control box 2 on the shell assembly 1, thereby realizing the connection and cooperation between the electrical control box 2 and the shell assembly 1.
[0042] Reference Figure 1 As shown, the duct enclosure 12 is horizontally arranged in the middle of the partition 11 in the vertical direction, so as to divide the arrangement space on one side of the partition 11 into two parts arranged vertically. The fan 3 and the electrical control box 2 can be arranged above the duct enclosure 12. The lower part of the duct enclosure 12 can be used to guide the airflow to realize the air supply function of the HVAC equipment 100.
[0043] Specifically, the electrical control box 2 is provided with a first mounting part 21 and a second mounting part 22. The first mounting part 21 is used to connect and cooperate with the middle partition 11, and the second mounting part 22 is used to connect and cooperate with the air duct enclosure 12, so that the electrical control box 2 can be arranged in the adjacent area of the middle partition 11 and the air duct enclosure 12, that is, the electrical control box 2 is arranged in the area that is close to both the middle partition 11 and the air duct enclosure 12.
[0044] The first mounting part 21 and the second mounting part 22 are respectively provided at the upper and lower ends of the electrical control box 2. The first mounting part 21 is connected and cooperates with the mounting seat 111 on the middle partition 11, and the second mounting part 22 is connected and cooperates with the air duct enclosure 12 located below the electrical control box 2, so as to fully constrain the electrical control box 2 on the middle partition 11 and the air duct enclosure 12, and the assembly reliability of the electrical control box 2 at the shell assembly 1 is high.
[0045] Currently, electrical control boxes in HVAC systems are typically located on the outdoor unit side for cooling by fans. This meets the cooling requirements of the control box during HVAC operation. However, this requires high-power fans (e.g., high static pressure fans), leading to higher costs. Furthermore, if the outdoor fans cannot meet the cooling demands, the control box may fail due to overheating. Related technologies place the control box on the indoor unit side for cooling by fans (e.g., high static pressure fans). However, installing the control box on the indoor unit side is complex and inconvenient for assembly.
[0046] According to the HVAC equipment 100 of the present application embodiment, the electrical control box 2 and the fan 3 in the HVAC equipment 100 are arranged in the same space, thereby meeting the heat dissipation requirements at the electrical control box 2. The electrical control box 2 is installed and cooperated with the partition plate 11 and the air duct enclosure plate 12 through the first mounting part 21 and the second mounting part 22 respectively, so as to improve the assembly reliability of the electrical control box 2 at the shell assembly 1.
[0047] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments of this application, the electrical control box 2 includes a box body 23 and a box cover 24. The box body 23 has a mounting groove 231 that opens to the side away from the middle partition 11, and a first mounting part 21 is disposed on the box body 23.
[0048] Furthermore, the cover 24 is placed on the box body 23, and the cover 24 is used to cover the open end of the mounting groove 231, so that the cover 24 and the box body 23 enclose a space for accommodating electronic components (such as PCB boards, wire harnesses, etc.) inside the electrical control box 2.
[0049] The main body 23 of the box has a mounting groove 231 that opens to the side opposite to the partition plate 11, and the open end of the mounting groove 231 is covered by a box cover 24. When the box cover 24 is removed from the box body, the electronic components inside the control box 2 can be fully exposed at the open end of the mounting groove 231. The testing or maintenance needs of the control box 2 can be met without disassembling the entire control box 2, which can reduce the difficulty of testing and maintenance of the control box 2.
[0050] It is understood that the second mounting part 22 is provided on at least one of the box body 23 and the box cover 24. That is, the second mounting part 22 can be provided on the box body 23, the second mounting part 22 can also be provided on the box cover 24, or the second mounting part 22 can be provided on both the box body 23 and the box cover 24. For example, when the electrical control box 2 is provided with multiple second mounting parts 22, all of the multiple second mounting parts 22 can be provided on the box body 23, all of the multiple second mounting parts 22 can be provided on the box cover 24, or a portion of the second mounting parts 22 can be provided on the box body 23 and another portion of the second mounting parts 22 can be provided on the box cover 24.
[0051] Combination Figure 3 and Figure 6 As shown, in some embodiments of this application, the second mounting part 22 is configured as a connecting flange, which is disposed on the cover 24. The connecting flange extends in the lateral direction and is used to connect and fix with the air duct enclosure 12.
[0052] The connecting flange is set horizontally, so that the connecting flange can be set to correspond with the air duct enclosure 12, making it easy to connect and cooperate with the connecting flange and the air duct enclosure 12.
[0053] Combination Figure 3 and Figure 6 As shown, the connecting flange is located at the lower end of the cover 24, and the connecting flange is bent from the main body of the cover 24 toward the side away from the partition 11, so that the connection between the connecting flange and the air duct enclosure 12 is formed in a suitable exposed position, so that the operator can connect and fix the connecting flange to the air duct enclosure 12, thereby realizing the fixed connection between the electrical control box 2 and the air duct enclosure 12.
[0054] Understandably, because the connecting flange is bent away from the partition 11, the connecting flange is fully exposed. In other words, in the vertical projection, no other parts or devices will obstruct the connection between the connecting flange and the air duct enclosure 12, thus providing ample operating space for operators to assemble and disassemble the cover 24.
[0055] Reference Figure 3 As shown, in some embodiments of this application, the connecting flange is provided with a mounting hole 221, which is used for the connector to pass through, so as to connect and fix the connecting flange to the air duct enclosure 12 through the connector, thereby realizing the fixed connection between the electrical control box 2 and the air duct enclosure 12. The connector can be constructed as a screw, bolt or other connecting component, and the specific construction of the connector is not limited here.
[0056] In this design, when the electrical control box 2 is connected to the duct enclosure 12, the connecting flange and the duct enclosure 12 are stacked together, and the connector can be inserted through the connecting flange and the duct enclosure 12 to connect and fix the connecting flange to the duct enclosure 12. The installation method is simple and highly reliable, which can ensure the connection reliability between the electrical control box 2 and the duct enclosure 12 and facilitate the subsequent maintenance of the electrical control box 2.
[0057] Combination Figure 3 and Figure 6 As shown, in some embodiments of this application, the connecting flange is provided with a positioning hole 222, and the air duct enclosure 12 is provided with a positioning protrusion 121 protruding upward (i.e. the side of the connecting flange). The positioning protrusion 121 can be positioned and engaged with the positioning hole 222 to position and engage the connecting flange with the air duct enclosure 12, thereby positioning and engaging the bottom of the electrical control box 2 with the air duct enclosure 12.
[0058] Specifically, the positioning hole 222 is provided through the thickness direction. Since the connecting flange is provided laterally, the positioning hole 222 is provided through the connecting flange in the vertical direction. When the positioning hole 222 and the positioning protrusion 121 are positioned and engaged, the bottom of the electrical control box 2 can be positioned in the horizontal direction, thereby positioning and engaging the connecting flange with the air duct enclosure 12, which facilitates further connection and fixation of the connecting flange with the air duct enclosure 12.
[0059] It is understandable that the connecting flange can be provided with both mounting holes 221 and positioning holes 222. When connecting the connecting flange to the duct enclosure 12, the positioning holes 222 can be used to engage with the positioning protrusions 121 on the duct enclosure 12 to position the connecting flange to the duct enclosure 12. This allows the mounting holes 221 to correspond to the mounting structures (such as hole structures) formed on the duct enclosure 12. Then, the connecting flange can be further fixedly connected to the duct enclosure 12 at the mounting holes 221 using connectors, thus fixing the electrical control box 2 to the duct enclosure 12.
[0060] Therefore, in the assembly of the electrical control box 2 with the air duct enclosure 12 via the second mounting part 22, the electrical control box 2 and the air duct enclosure 12 can be connected and fixed by positioning first and then connecting and fixing. The installation method is easy to operate and highly reliable, which can ensure the installation reliability of the electrical control box 2 at the shell assembly 1.
[0061] Reference Figure 1 and Figure 2 As shown, in some embodiments of this application, the lid 24 has a connecting edge 241, which is located on the outer side of the side wall of the box body 23 and is used to connect and fix with the side wall of the box body 23 to fix the lid 24 to the box body 23.
[0062] It is understandable that when the lid 24 and the body 23 are fitted together, the connecting edge 241 covers the outer side of the side wall of the body 23, so that the connecting edge 241 and the side wall of the body 23 are correspondingly set. Thus, the connecting edge 241 and the body 23 can be connected and fixed by connecting parts (such as screws). The connection method is simple and highly reliable, and it can also ensure the covering effect of the lid 24 on the open side of the body 23.
[0063] like Figure 1 As shown, in some embodiments of this application, a wire passing part 232 is provided on the side wall of the box body 23. The wire passing part 232 is used for the wire harness to be led out from the inside of the box body 23, so that the electronic components (such as PCB board, etc.) in the electrical control box 2 can be electrically connected and cooperated with the equipment (such as fan 3, etc.) arranged in the indoor unit side space through the wire harness, so as to meet the wiring requirements of the electrical control box 2.
[0064] When the electrical control box 2 is connected and fitted with the partition plate 11 and the duct enclosure 12, the bottom wall of the electrical control box 2 and the duct enclosure 12 are vertically opposite each other. The wall of the box body 23, which is opposite to the open end of the slot structure, is positioned close to the partition plate 11. By setting the wire passage 232 on the side wall of the box body 23, the protection effect of the electrical control box 2 can be improved while meeting the wire passage requirements. It is understandable that if the wire passage 232 is located on the top wall of the electrical control box 2, dust and other contaminants will easily enter the electrical control box 2 through the wire passage 232; if the wire passage 232 is located on the box cover 24, the wiring of the electrical control box 2 will be more difficult. In this application, by setting the wire passage 232 on the side wall of the box body 23, the wire passage hole can be led out from the side of the box body 23, which facilitates the wiring and can also play a certain role in dust prevention.
[0065] Combination Figure 4 and Figure 5 As shown, in some embodiments of this application, the mounting base 111 is provided with an upwardly open snap-fit groove 1111, and the first mounting part 21 is constructed as a snap hook. The snap hook can be snapped into the snap-fit groove 1111 from top to bottom, and the electrical control box 2 is hung on the mounting base 111 of the middle partition plate 11. Thus, the electrical control box 2 is pre-installed on the middle partition plate 11 by the snap-fit cooperation between the first mounting part 21 and the mounting base 111.
[0066] The mounting base 111 has an upward-opening slot 1111, allowing the first mounting part 21 to engage with the slot 1111 from top to bottom, thus hanging the electrical control box 2 on the partition 11. This installation method is simple and easy to operate. In other words, during the installation of the electrical control box 2 and the partition 11, the electrical control box 2 is hung on the mounting base 111 of the partition 11 via the first mounting part 21. That is, the upper end of the electrical control box 2 is not fixedly connected to the partition 11, making it easier to remove the electrical control box 2 from the partition 11 and reducing the difficulty of disassembling and assembling the electrical control box 2 at the housing assembly 1.
[0067] Understandably, during the installation of the electrical control box 2, it can first be hung on the mounting seat 111 of the partition 11 via the first mounting part 21 to achieve pre-installation of the electrical control box 2 at the partition 11. Then, the electrical control box 2 is connected and fixed to the duct enclosure 12 via the second mounting part 22 to fix the electrical control box 2 onto the shell assembly 1. When it is necessary to remove the electrical control box 2 from the shell assembly 1, it is only necessary to disassemble the second mounting part 22 from the duct enclosure 12. The electrical control box 2 can then be removed from the partition 11 by lifting it upwards. This makes the disassembly of the electrical control box 2 easy and facilitates the operator to remove the electrical control box 2 from the shell assembly 1 for maintenance.
[0068] The first mounting part 21 is disposed on the box body 23, and the first mounting part 21 is located on the side of the box body 23 near the middle partition 11, so as to facilitate the first mounting part 21 to be snapped into the middle partition 11.
[0069] like Figure 5 As shown in a further embodiment of this application, the first mounting portion 21 includes a first plate segment 211 and a second plate segment 212. The first plate segment 211 is connected to the top wall of the electrical control box 2, and a portion of the first plate segment 211 protrudes from the electrical control box 2 towards the partition plate 11. The second plate segment 212 is connected to the end of the first plate segment 211, and the second plate segment 212 extends downward in a vertical direction from the end of the first plate segment 211. The second plate segment 212 can extend into the snap-fit groove 1111 to snap-fit the first mounting portion 21 with the mounting base 111.
[0070] Reference Figure 5 The first plate segment 211 is installed on the box body 23 of the electrical control box 2, and the first plate segment 211 is connected and engaged with the top wall of the box body 23 to place the first mounting part 21 at the upper end of the electrical control box 2. The first plate segment 211 extends laterally, and one end of the first plate segment 211 protrudes towards the middle partition 11, so that the second plate segment 212 connected to the end of the first plate segment 211 is spaced apart from the box body 23 to form a clearance space between the second plate segment 212 and the box body 23. The clearance space can accommodate the mounting seat 111, so that when the first mounting part 21 and the mounting seat 111 are engaged, part of the mounting seat 111 can be located within the clearance space between the second plate segment 212 and the box body 23.
[0071] Understandably, the first plate segment 211 and the second plate segment 212 are arranged vertically to construct the first mounting portion 21 as an L-shaped plate. When the electrical control box 2 is installed and engaged with the housing assembly 1, the second plate segment 212 can fit tightly against the vertical wall surface of the mounting base 111.
[0072] Combination Figure 4 and Figure 5 As shown, in some embodiments of this application, a support layer 25 is provided on the side surface of the electrical control box 2 opposite to the partition plate 11. The support layer 25 is supported between the electrical control box 2 and the partition plate 11, so as to support and position the electrical control box 2 relative to the partition plate 11 through the support layer 25, thereby tightly fitting the second plate segment 212 with the vertical wall surface of the mounting base 111 and preventing the electrical control box 2 from shaking relative to the partition plate 11.
[0073] The thickness of the support layer 25 is greater than the gap between the electrical control box 2 and the partition plate 11, so that after the electrical control box 2 is supported and positioned by the air duct enclosure 12, it can cooperate with the partition plate 11 to press against the support layer 25, thereby supporting and positioning the electrical control box 2 through the support layer 25. In other words, the support layer 25 sandwiched between the box body 23 and the partition plate 11 has a tendency to drive the box body 23 to move away from the partition plate 11.
[0074] Combination Figure 4 and Figure 5 As shown, it can be understood that the hook is inserted into the mounting groove 231 from top to bottom. Under the support of the support layer 25, the box body 23 is supported away from the middle partition 11. Since the upper part of the box body 23 is hung on the mounting base 111 by the hook, the second plate segment 212 in the hook can be fitted with the vertical wall of the mounting base 111 near the box body 23. Thus, under the constraint of the hook and the mounting base 111 and the support of the support layer 25, the upper end of the box body 23 is positioned relative to the middle partition 11.
[0075] Further integration Figure 6 As shown, the electrical control box 2 is connected and fixed to the air duct enclosure 12 through the second mounting part 22, thereby fixing the lower end of the electrical control box 2 to fix the bottom of the electrical control box 2 relative to the middle partition 11, so that the bottom of the box body 23 cannot move away from the middle partition 11 under the support of the support layer 25. Thus, the support layer 25 can be squeezed by the cooperation of the box body 23 and the middle partition 11, and the upper part of the box body 23 can be supported and positioned away from the middle partition 11 by the support layer 25, so as to assemble and fix the electrical control box 2 on the shell assembly 1.
[0076] In some embodiments of this application, the support layer 25 can be constructed as a sponge layer. The sponge layer has good deformation properties so that when the electrical control box 2 and the air duct enclosure 12 are positioned and engaged, the sponge layer is squeezed by the electrical control box 2 and the middle partition 11, so that the sponge layer can play an elastic support role for the electrical control box 2 and prevent the electrical control box 2 from shaking relative to the middle partition 11.
[0077] In some embodiments of this application, a heat insulation layer 112 is provided on the side surface of the partition 11 opposite to the electrical control box 2, and a support layer 25 is sandwiched and supported between the heat insulation layer 112 and the electrical control box 2. This can block the heat exchange between the indoor unit side and the outdoor unit side through the heat insulation layer 112, reduce the influence of the outdoor unit side temperature on the indoor unit side, and help ensure the temperature regulation effect of the indoor unit side.
[0078] It is understandable that the partition 11 divides the two sides of the shell assembly 1 to form an indoor unit side arrangement space and an outdoor unit side arrangement space. By setting the heat insulation layer 112 on the partition 11, the heat exchange between the indoor unit side and the outdoor unit side can be effectively blocked, so as to reduce the influence of the outdoor unit side temperature on the indoor unit side.
[0079] In one specific embodiment of this application, the heat insulation layer 112 is constructed as a fiberglass cotton layer (i.e., glass fiber cotton). Fiberglass cotton has an extremely low thermal conductivity, which can effectively prevent heat transfer and absorb sound waves through its porous structure to improve the acoustic environment.
[0080] In some embodiments of this application, the duct enclosure 12 is provided with enclosure flange 122, at least a portion of the enclosure flange 122 is provided at one end of the duct enclosure 12 near the middle partition 11, and the enclosure flange 122 is located on the side of the support layer 25 facing the heat insulation layer 112, and the duct flange can abut against the heat insulation layer 112 to improve the sealing effect at the joint between the duct enclosure 12 and the middle partition 11.
[0081] Reference Figure 4 As shown, the flange 122 of the enclosure is located on the side of the electrical control box 2 facing the middle partition 11, and the flange 122 of the enclosure is located on the side of the support layer 25 facing the middle partition 11, so as to prevent interference between the flange 122 of the enclosure and the support layer 25, and the flange 122 of the enclosure can abut against the heat insulation layer 112 on the middle partition 11.
[0082] It is understood that the duct enclosure 12 can also be used to connect and cooperate with the partition 11 to connect and fix the partition 11 and the duct enclosure 12. The duct enclosure 12 can be provided with multiple enclosure flanges 122 in the circumferential direction, so that the duct enclosure 12 can be connected and cooperate with the panel structure in the shell assembly 1 through the enclosure flanges 122, thereby meeting the assembly and fixing requirements of the duct enclosure 12 in the shell assembly 1.
[0083] Reference Figures 1-6 The assembly process of the electrical control box 2 in the HVAC equipment 100 according to an embodiment of this application is described below:
[0084] After the box body 23 and the box cover 24 are assembled, the electrical control box 2 is hung on the mounting seat 111 of the middle partition 11 by the first mounting part 21 (i.e., the hook) so as to pre-install the electrical control box 2 on the middle partition 11.
[0085] Furthermore, the second mounting part 22 is correspondingly set with the air duct enclosure 12, and the second mounting part 22 is positioned and engaged with the air duct enclosure 12. Then, the second mounting part 22 is connected and fixed with the air duct enclosure 12 through the connector, so as to assemble and fix the electrical control box 2 on the shell assembly 1.
[0086] When the second mounting part 22 is connected to the air duct enclosure 12, the support layer 25 can support the box body 23, so that the electrical control box 2 is supported and positioned by the support layer 25 and the constraint cooperation between the first mounting part 21 and the mounting base 111.
[0087] When it is necessary to disassemble the electrical control box 2, simply disassemble the connector to release the second mounting part 22 from the air duct enclosure 12, and remove the electrical control box 2 from the mounting seat 111 of the partition 11 by lifting it upwards. The disassembly method is simple and easy to operate, which can reduce the difficulty of testing and maintenance of the electrical control box 2.
[0088] The HVAC equipment 100 according to the embodiments of this application has at least the following advantages over the prior art:
[0089] (1) The electrical control box 2 and the fan 3 in the HVAC equipment 100 are arranged in the same space so that heat dissipation can be achieved by the fan 3 (e.g., high static pressure fan) on the indoor unit side of the HVAC equipment 100. This can improve the heat dissipation and cooling effect of the HVAC equipment 100 at the electrical control box 2. The electrical control box 2 can be first hung on the middle partition 11 through the first mounting part 21, and then further installed and fixed on the air duct enclosure 12 through the second mounting part 22. The installation method of the electrical control box 2 is simple and reliable, and it is easy to disassemble and assemble the electrical control box 2, reducing the difficulty of maintenance operation of the electrical control box 2.
[0090] (2) A support layer 25 is provided between the electrical control box 2 and the middle partition 11 to support and position the electrical control box 2, thereby ensuring the installation reliability of the electrical control box 2.
[0091] (3) The second mounting part 22 includes a positioning hole 222 and a mounting hole 221. The second mounting part 22 can be positioned and matched with the air duct enclosure 12 by the positioning structure first, and then the second mounting part 22 can be connected and fixed to the air duct enclosure 12 by the connector. This can reduce the difficulty of the installation process and improve the disassembly and assembly efficiency of the electrical control box 2.
