[0002] Currently, rooftop units are HVAC systems that combine indoor and outdoor units into one unit. They are characterized by their compact structure and can be directly installed on the roof to save ground space.

[0003] The rooftop unit has its indoor and outdoor units arranged adjacent to each other, and the indoor unit has high static pressure suction.

[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 1-3 The present application describes a housing 100 for a heating, ventilation, and air conditioning (HVAC) system according to an embodiment of the present application. The housing 100 serves as a mounting carrier for multiple devices (such as compressors, fans, heat exchangers, etc.) in the HVAC system, thereby requiring the housing 100 to have good protective effects to prevent the HVAC system from malfunctioning due to external environmental influences during operation.

[0036] Among them, HVAC equipment can be constructed as rooftop units. Rooftop units are HVAC equipment that combines indoor and outdoor units into one unit. They are characterized by their compact structure and can be directly installed on the roof to save ground space.

[0037] The rooftop unit has its indoor and outdoor units arranged adjacent to each other, and the indoor unit has high static pressure suction. When outdoor weather conditions are severe (e.g., rain), water and other contaminants located outside the rooftop unit may enter the indoor unit's arrangement space through the gap between the indoor and outdoor unit chassis. Additionally, rainwater may enter the indoor unit's arrangement space from the outdoor unit's arrangement space, potentially causing dripping water or other problems inside the user's home.

[0038] In related technologies, the protective effect of the housing 100 on the inner unit side is usually improved by applying glue to the gaps. However, as the rooftop unit is used for a long time, the glue ages, which affects the sealing effect.

[0039] According to an embodiment of this application, the housing 100 for HVAC equipment includes: a chassis body 1, a partition 2, a first chassis 3, and a second chassis 4.

[0040] The partition 2 is vertically arranged, and the housing 100 can be divided into accommodating spaces by the partition 2 to form adjacent and independently arranged indoor unit side spaces and outdoor unit side spaces. The above-mentioned "independent" arrangement of the indoor unit side spaces and outdoor unit side spaces means that the indoor unit side spaces and outdoor unit side spaces are separated by the partition 2 and are not connected by the partition 2.

[0041] Combination Figure 1 and Figure 2 As shown, a first chassis 3 is mounted on a chassis body 1. A first connecting plate segment 31 is provided at one end of the first chassis 3 near the partition 2. Part of the first connecting plate segment 31 is positioned opposite the partition 2 in a first direction. A second chassis 4 is mounted on the chassis body 1. The second chassis 4 and the first chassis 3 are arranged along a first direction. A second connecting plate segment 41 is provided at one end of the second chassis 4 near the first chassis 3. The second connecting plate segment 41 is located on the side of the first connecting plate segment 31 away from the partition 2 in the first direction. The second connecting plate segment 41 and the first connecting plate segment 31 are positioned opposite each other in the first direction. This arrangement allows the first connecting plate segment 31, the second connecting plate segment 41, and the partition 2 to be arranged correspondingly in the first direction, enabling them to be stacked and connected in the first direction. This improves the structural strength of the connection points between the first chassis 3, the second chassis 4, and the partition 2, and enhances the protective effect between the first chassis 3 and the partition 2.

[0042] The first chassis 3 is the outer chassis of the shell 100. The first chassis 3 is used to provide support for the outdoor unit side equipment in the space where the HVAC equipment is arranged on the outdoor unit side, so as to realize the installation and fixation of the outdoor unit side equipment (such as compressor, fan, heat exchanger, etc.); the second chassis 4 is the inner chassis of the shell 100. The second chassis 4 is used to provide support for the indoor unit side equipment in the space where the HVAC equipment is arranged on the indoor unit side, so as to realize the installation and fixation of the indoor unit side equipment (such as heat exchanger, etc.).

[0043] It is understood that the partition 2 is vertically arranged in the housing 100 to separate the housing 100 into an indoor unit side arrangement space and an outdoor unit side arrangement space arranged along a first direction. The first chassis 3 is used to provide installation support for the outdoor unit side equipment in the outdoor unit side arrangement space, and the second chassis 4 is used to provide installation support for the indoor unit side equipment in the indoor unit side arrangement space. The first direction refers to the thickness direction of the partition 2.

[0044] Furthermore, it can be understood that since the partition plate 2 is arranged vertically, and at least a portion of the first connecting plate segment 31 also extends vertically, the first connecting plate segment 31 and the partition plate 2 are arranged correspondingly in the first direction. Simultaneously, the second connecting plate segment 41 is located on the side of the first connecting plate segment 31 away from the partition plate 2 in the first direction, and the second connecting plate segment 41 is arranged opposite to the first connecting plate segment 31 in the first direction. Therefore, at least a portion of the second connecting plate segment 41 also extends vertically, allowing the second connecting plate segment 41 to be arranged opposite to the first connecting plate segment 31 in the first direction. This stacking of the second connecting plate segment 41, the first connecting plate segment 31, and the partition plate 2 in the first direction helps to improve the structural strength of the housing 100 at the connection and mating points of the first chassis 3, the second chassis 4, and the partition plate 2.

[0045] Reference Figure 3 As shown, since the first connecting plate segment 31, the second connecting plate segment 41 and the middle partition 2 are stacked and connected in the first direction, the second connecting plate segment 41, the first connecting plate segment 31 and the middle partition 2 can fit tightly in the first direction to improve the sealing and protection effect between the first connecting plate segment 31 and the second connecting plate segment 41, and between the first connecting plate segment 31 and the middle partition 2.

[0046] The first chassis 3 and the second chassis 4 are connected and fitted together in a first direction via a first connecting plate segment 31 and a second connecting plate segment 41. This allows the first connecting plate segment 31 and the second connecting plate segment 41 to be connected and fixed while being stacked, ensuring a tight fit between them in the first direction. This prevents water from outside the housing 100 from being sucked into the indoor unit side arrangement space through the gap between the first chassis 3 and the second chassis 4. Simultaneously, in the first direction, the first connecting plate segment 31 is positioned between the partition plate 2 and the second connecting plate segment 41, thereby ensuring a tight fit between the first connecting plate segment 31 and the partition plate 2 in the first direction. This prevents contaminants (such as rainwater) in the outdoor unit side arrangement space from entering the indoor unit side arrangement space through the gap between the first connecting plate segment 31 and the partition plate 2. Therefore, the stacked and connected arrangement of the first connecting plate segment 31, the second connecting plate segment 41, and the partition plate 2 in the first direction enhances the protective effect of the HVAC equipment in the indoor unit side arrangement space of the housing 100.

[0047] According to the embodiments of this application, the housing 100 for HVAC equipment has a first connecting plate segment 31, a second connecting plate segment 41, and a middle partition 2 stacked and connected in a first direction, thereby forming a multi-layer plate structure through the first connecting plate segment 31, the second connecting plate segment 41, and the middle partition 2. This improves the structural strength of the first chassis 3 and the second chassis 4 at the joint, and prevents rainwater and other pollutants from entering the indoor unit side arrangement space from the outside of the housing 100 or the outdoor unit side arrangement space, thus helping to improve the protective effect of the housing 100 in the indoor unit side arrangement space.

[0048] like Figure 3 As shown, in some embodiments of this application, the first connecting plate segment 31 includes a first flange 311, which is bent vertically upward and is disposed opposite to the middle partition plate 2 in a first direction; the second connecting plate segment 41 includes a second flange 411, which is bent vertically upward and is disposed opposite to the first flange 311 in a first direction.

[0049] Specifically, a first connecting plate segment 31 is formed at one end of the first chassis 3 near the partition 2, and a first flange 311 is bent upward from the first chassis 3, so that the first chassis 3 can extend from below the partition 2 to the side of the partition 2 facing the second chassis 4 (which is also the side surface of the partition 2 facing the interior unit side where the space is arranged), and the first flange 311 and the side surface of the partition 2 facing the second chassis 4 are arranged opposite each other in the first direction; a second connecting plate segment 41 is formed at one end of the second chassis 4 near the first chassis 3, and a second flange 411 is bent upward from the second chassis 4, so that the second flange 411 and the first flange 311 are arranged opposite each other in the first direction. Thus, by arranging the first flange 311, the second flange 411 and the partition 2 sequentially along the first direction to form a multi-layer plate structure, the structural strength of the connection and mating joint of the first flange 311, the second flange 411 and the partition 2 can be improved.

[0050] Reference Figure 3 As shown, by bending both the first flange 311 and the second flange 411 upwards, it is convenient to position the first flange 311 and the second flange 411 at the corresponding positions of the partition plate 2 arranged above the chassis body 1, so that the second flange 411, the first flange 311, and the partition plate 2 can be stacked along the first direction. At the same time, the first flange 311 is located between the second flange 411 and the partition plate 2. After the first flange 311 and the partition plate 2 are connected and cooperated, a protective structure can be formed at the first chassis 3 and the partition plate 2 to prevent rainwater and other pollutants in the outdoor unit side arrangement space from being sucked into the indoor unit side arrangement space through the gap between the first chassis 3 and the partition plate 2.

[0051] Combination Figure 2 and Figure 3 As shown, in some embodiments of this application, the housing 100 further includes a chassis cover plate 5, which covers the second chassis 4. A third connecting plate segment 51 is formed at one end of the chassis cover plate 5 near the middle partition plate 2. The third connecting plate segment 51 is disposed on the side of the second connecting plate segment 41 away from the first connecting plate segment 31. The third connecting plate segment 51 is connected and engaged with the second connecting plate segment 41 to connect and fix the chassis cover plate 5 to the second chassis 4.

[0052] Reference Figure 3 As shown, the third connecting plate segment 51 is located on the side of the second connecting plate segment 41 away from the first connecting plate segment 31, so that the second connecting plate segment 41 is positioned in a position corresponding to the second connecting plate segment 41, so that the chassis cover plate 5 and the second chassis 4 are fixed by the connection and cooperation between the second connecting plate segment 41 and the third connecting plate segment 51.

[0053] Combination Figure 2 and Figure 3 As shown, in some embodiments of this application, the chassis cover plate 5 and the second chassis 4 together form a cavity 501, and a heat insulation component 61 is provided in the cavity 501. The heat insulation component 61 has good heat insulation function and can form a heat insulation protection structure at the bottom of the space arranged on the indoor unit side to reduce the influence of the external ambient temperature on the temperature of the indoor unit side.

[0054] Understandably, the insulation component 61 can be filled into the cavity 501, thereby blocking heat exchange between the indoor unit side and the outer side of the casing 100, which helps to ensure the temperature regulation effect of the indoor unit side. The insulation component 61 can be constructed as fiberglass wool (i.e., glass fiber cotton). Fiberglass wool has an extremely low thermal conductivity, which can effectively prevent heat transfer, and its porous structure can absorb sound waves to improve the acoustic environment.

[0055] like Figure 3 As shown in a further embodiment of this application, the third connecting plate segment 51 includes a third flange 511, which is bent vertically upward from the chassis cover plate 5. The third flange 511 is located on the side of the second flange 411 away from the first flange 311 in the first direction, and the third flange 511 and the second flange 411 are arranged opposite to each other in the first direction, so that the third flange 511 and the second flange 411 are stacked to form a double-layer plate structure through the second flange 411 and the third flange 511, which helps to improve the structural strength at the joint of the second flange 411 and the third flange 511.

[0056] It is understandable that a heat insulation component 61 needs to be arranged in the cavity 501 formed between the chassis cover plate 5 and the second chassis 4. By bending the third flange 511 upward, the third flange 511 and the second flange 411 can be arranged correspondingly in the first direction, and the third flange 511 can be exposed on the outside of the cavity 501, which makes it convenient for the operator to connect and cooperate the second flange 411 and the third flange 511.

[0057] By setting a third flange 511 at the edge of the chassis cover plate 5, the structural strength of the chassis cover plate 5 can be improved, thereby enhancing the anti-deformation performance of the chassis cover plate 5 at the edge.

[0058] In some embodiments of this application, the housing 100 further includes a first connector (not shown in the figure), which can pass through the third flange 511, the second flange 411, the first flange 311 and the middle partition 2 along the first direction, and connect and fix the third flange 511, the second flange 411, the first flange 311 and the middle partition 2.

[0059] It is understandable that the third flange 511, the second flange 411, the first flange 311, and the partition plate 2 are stacked to form a multi-layer (specifically four-layer) structure at the joint between the second chassis 4 and the first chassis 3, which can improve the structural strength of the joint between the second chassis 4 and the first chassis 3. Simultaneously, the third flange 511, the second flange 411, the first flange 311, and the partition plate 2 are arranged correspondingly in the first direction, allowing the first connector to pass through the third flange 511, the second flange 411, the first flange 311, and the partition plate 2 along the first direction, connecting and fixing them in the first direction. This ensures a tight fit between the third flange 511, the second flange 411, the first flange 311, and the partition plate 2 in the first direction, thereby improving the sealing and protective effect between the second flange 411 and the first flange 311, and between the first flange 311 and the partition plate 2.

[0060] The first connector can be constructed as a threaded connector (such as a bolt or screw). The installation direction of the first connector is not specifically limited here. That is to say, the first connector can be installed from the indoor unit side to sequentially pass through the third flange 511, the second flange 411, the first flange 311, and the middle partition 2; the first connector can also be installed from the outdoor unit side to sequentially pass through the middle partition 2, the first flange 311, the second flange 411, and the third flange 511.

[0061] In a further embodiment of this application, there are multiple first connectors, which are sequentially arranged along a second direction to fully fix the third flange 511, the second flange 411, the first flange 311, and the middle partition 2, thereby improving the connection reliability. The second direction is horizontal and is perpendicular to both the first and vertical directions.

[0062] It should be noted that the number of first connectors can be 4, 5, 6, etc. There is no specific limit to the number of first connectors here. The number of first connectors can be set according to the connection requirements of the third flange 511, the second flange 411, the first flange 311 and the middle partition 2.

[0063] like Figure 3 As shown, in some embodiments of this application, the first connecting plate segment 31 further includes a fourth flange 312, which is bent from the upper edge of the first flange 311 toward a first side in a first direction; the second connecting plate segment 41 further includes a fifth flange 412, which is bent from the upper edge of the second flange 411 toward a first side in a first direction; the third connecting plate segment 51 further includes a sixth flange 512, which is bent from the upper edge of the third flange 511 toward a first side in a first direction.

[0064] Among them, the fourth flange 312, the fifth flange 412 and the sixth flange 512 are stacked from top to bottom, thereby further improving the structural strength of the joint between the first chassis 3, the second chassis 4 and the chassis cover plate 5.

[0065] Specifically, by providing a fourth flange 312 along the upper edge of the first flange 311, the structural strength of the first connecting plate segment 31 and its resistance to deformation can be improved; by providing a fifth flange 412 along the upper edge of the second flange 411, the structural strength of the second connecting plate segment 41 and its resistance to deformation can be improved; and by providing a sixth flange 512 along the upper edge of the third flange 511, the structural strength of the third connecting plate segment 51 and its resistance to deformation can be improved. This further enhances the structural strength at the mating point of the first chassis 3 and the second chassis 4.

[0066] Reference Figure 3As shown, the first side of the first direction refers to the side of the first flange 311 that faces away from the partition 2, the side of the second flange 411 that faces away from the first flange 311, or the side of the third flange 511 that faces away from the second flange 411. Therefore, extending the fourth flange 312, the fifth flange 412, and the sixth flange 512 towards the same side allows them to be stacked to form a multi-layered structure. This helps improve the structural strength at the junction of the first chassis 3 and the second chassis 4, and also allows the fourth flange 312, the fifth flange 412, and the sixth flange 512 to avoid interference with the partition 2.

[0067] In a further embodiment of this application, the housing 100 also includes a second connector (not shown in the figure). The second connector can pass through the fourth flange 312, the fifth flange 412 and the sixth flange 512 in the vertical direction, and is used to connect and fix the fourth flange 312, the fifth flange 412 and the sixth flange 512, so as to further improve the connection reliability between the first chassis 3, the second chassis 4 and the chassis cover plate 5 through the connection and cooperation of the fourth flange 312, the fifth flange 412 and the sixth flange 512.

[0068] It is understood that the connection position of the second connector is set at the overlapping area of ​​the projection of multiple flanges (i.e., the fourth flange 312, the fifth flange 412 and the sixth flange 512 mentioned above) in the vertical direction, so as to connect and fix the fourth flange 312, the fifth flange 412 and the sixth flange 512 through the same connecting component (i.e. the second connector).

[0069] The second connector can be installed with the fourth flange 312, the fifth flange 412 and the sixth flange 512 sequentially from top to bottom. The top-to-bottom installation can provide sufficient operating space for the installation of the second connector and reduce the difficulty of operation for the operator.

[0070] In some embodiments of this application, there are multiple second connectors, which are arranged sequentially along a second direction, thereby fully fixing the fourth flange 312, the fifth flange 412, and the sixth flange 512.

[0071] In some embodiments of this application, the fourth flange 312 protrudes from the fifth flange 412 along the first direction to the first side, thereby fully corresponding the fourth flange 312 and the fifth flange 412 so as to facilitate the connection and cooperation between the fourth flange 312 and the fifth flange 412.

[0072] In some embodiments of this application, the fifth flange 412 protrudes from the sixth flange 512 along the first direction to the first side, thereby fully corresponding the fifth flange 412 and the sixth flange 512 so as to facilitate the connection and cooperation between the fifth flange 412 and the sixth flange 512.

[0073] Reference Figure 3 As shown, the fourth flange 312 can be configured to protrude from the fifth flange 412 and the sixth flange 512 to the first side of the first direction, and the fifth flange 412 can be configured to protrude from the sixth flange 512 to the first side of the first direction, so that the fourth flange 312, the fifth flange 412 and the sixth flange 512 can be fully corresponded.

[0074] Among them, a multi-layered "I" structure can be formed at the first connecting plate segment 31, the second connecting plate segment 41 and the third connecting plate segment 51, which helps to improve the structural strength of the mating parts of the first chassis 3, the second chassis 4 and the chassis cover plate 5.

[0075] Meanwhile, the first connecting plate segment 31, the second connecting plate segment 41, and the third connecting plate segment 51 can be connected and fixed from multiple directions by connecting components (such as the first connecting member and the second connecting member mentioned above), which can improve the connection reliability of the first connecting plate segment 31, the second connecting plate segment 41, and the third connecting plate segment 51. Furthermore, the multi-layered structure formed by the first connecting plate segment 31, the second connecting plate segment 41, and the third connecting plate segment 51 can effectively improve the rigidity of the first chassis 3, the second chassis 4, and the chassis cover plate 5 at the connection and mating points.

[0076] It should be noted that the first connector is installed horizontally and the second connector is installed vertically, so that the first connecting plate segment 31, the second connecting plate segment 41 and the third connecting plate segment 51 can be connected and fixed from two intersecting directions, which can improve the connection reliability of the first connecting plate segment 31, the second connecting plate segment 41 and the third connecting plate segment 51.

[0077] like Figure 3 As shown, in some embodiments of this application, the lower end of the partition plate 2 is provided with a partition flange 21, which is bent toward the second side in the first direction, and the partition flange 21 is disposed opposite to a portion of the first chassis 3 in the vertical direction. The partition flange 21 can improve the structural strength of the lower end of the partition plate 2, thereby improving the deformation resistance of the lower end of the partition plate 2.

[0078] It is understandable that the partition flange 21 is bent from the lower end of the middle partition 2 toward the second side in the first direction (which is also the side of the middle partition 2 away from the first flange 311). The partition flange 21 can block the gap between the middle partition 2 and the first flange 311, thereby increasing the difficulty for pollutants to enter the gap between the middle partition 2 and the first flange 311 and improving the sealing and protection effect between the middle partition 2 and the first flange 311.

[0079] In some embodiments of this application, the chassis body 1 is constructed as a frame structure consisting of multiple beam segments connected end to end, such as a rectangular frame. The chassis body 1 serves as the mounting carrier for the first chassis 3 and the second chassis 4, and can be used to install and fix the first chassis 3 and the second chassis 4.

Furthermore, installation and fixing in multiple directions can be achieved at the joint to improve the connection reliability of the partition plate 2, the first chassis 3, the second chassis 4 and the chassis cover plate 5, which helps to improve the overall strength of the shell in the bottom area.

[0083] (2) The partition 2 is located on the side of the first connecting plate section 31 away from the second connecting plate section 41, so that the partition 2 and the first connecting plate section 31 can cooperate to form a sealed protection on the outdoor unit side to prevent contaminants on the outdoor unit side from entering the indoor unit side through the gap between the partition 2 and the first connecting plate section 31.

[0084] At the junction of the first connecting plate section 31 and the second connecting plate section 41, the first flange 311 and the second flange 411 are connected and fitted together to form a protective structure between the first chassis 3 and the second chassis 4 through the tight fit of the first flange 311 and the second flange 411, preventing contaminants outside the housing 100 from entering the indoor unit side through the gap between the first chassis 3 and the second chassis 4.

[0085] According to an embodiment of this application, the heating and ventilation equipment includes the housing 100 described above.

[0086] The HVAC equipment can be constructed as a rooftop unit, and the advantages of the HVAC equipment compared to existing technical solutions are the same as those of the aforementioned housing 100, which will not be repeated here.
