Description

Technical Field

[0001] This utility model relates to the field of fresh air equipment technology, and in particular to a frame and a fresh air integrated unit. Background Technology

[0002] With the development of building environmental control technology, people's requirements for indoor air quality and thermal comfort are increasing. This has led to the emergence of integrated fresh air conditioning units that combine fresh air exchange and temperature control. This technology features a compact structure and integrated functions, aiming to solve the problems of traditional independent fresh air systems' inability to effectively control supply air temperature and traditional air conditioners' inability to provide sufficient fresh air. Current traditional units typically employ an integrated cabinet design, dividing the unit into different functional areas through internal partitions or sheet metal structures. For example, the fresh air intake area, heat exchange area, and outdoor unit (compressor) area are integrated into a single enclosure to minimize space occupation and facilitate installation.

[0003] In traditional technologies, the interior of the air conditioning unit is typically physically partitioned using vertical or horizontal partitions. For example, Chinese patent application CN114935187A discloses an energy-saving, spray-type integrated fresh air conditioning unit with dual winter and summer operating conditions. This device divides the entire unit into an air intake area and a combined area using vertical panels, and further divides the combined area into a fresh air section and a return air section using vertical panels. This partitioned layout, combined with a condensate spray system, achieves energy savings. However, the partitions in such devices are usually only used as simple physical space dividers (such as single-layer sheet metal structures). While they achieve the division of airflow channels, they have significant shortcomings in terms of thermodynamic isolation. Specifically, although this patent lowers the compressor's operating point using a water system, it does not specifically address the thermal conductivity of the partition itself, resulting in a significant thermal bridging effect on both sides of the partition.

[0004] However, the current rack structure of integrated fresh air systems still has significant problems in practical applications. Because the fresh air module (which typically requires lower temperatures to ensure comfortable airflow) and the outdoor unit module (containing the high-heat-generating compressor) are physically adjacent, traditional single-layer partitions are insufficient to effectively prevent heat transfer. This allows heat generated by the compressor to easily transfer to the fresh air side through the partition, reducing cooling efficiency. More seriously, when the temperature difference between the two sides of the partition is too large, condensation easily forms on its surface. If this condensation is not effectively suppressed or drained in time, it accumulates and drips onto other electronic components or insulation materials inside the unit, causing moisture damage, mold growth, and even short circuits, severely impacting the equipment's lifespan and safety. Utility Model Content

[0005] Therefore, it is necessary to provide a rack and integrated air purifier to address the above issues.

[0006] This application provides a frame for an integrated fresh air unit, including a partition disposed between a fresh air module and an outdoor unit module. The edge of the partition body is bent toward the outdoor unit module to form a bent portion. The bent portion and the partition body together form a mounting cavity. The mounting cavity is filled with a filler to block the heat generated by the compressor from being transferred to the fresh air module and to reduce the formation of condensate on the partition.

[0007] Optionally, the filler is a foam insulation board.

[0008] Optionally, the filler is a vacuum multilayer board.

[0009] Optionally, the mounting cavity is an empty cavity, and the inner wall surface of the mounting cavity is coated with a coating.

[0010] Optionally, the coating is hollow glass microspheres.

[0011] This application also provides a frame for a fresh air unit, the frame including a partition and a panel, the partition and the panel forming a first receiving cavity and a second receiving cavity, the first receiving cavity and the second receiving cavity being arranged in a vertical direction, the fresh air module being disposed in the first receiving cavity, the outdoor unit module being disposed in the second receiving cavity, the partition having a mounting cavity, and a medium being disposed in the mounting cavity.

[0012] Optionally, the medium is a foam material.

[0013] Optionally, the inner wall of the mounting cavity is coated with a heat-insulating coating, and the medium is air.

[0014] Optionally, the panel is provided with an access port suitable for the maintenance of the compressor and electronic control components, and an access cover plate adapted to the access port.

[0015] This application also provides a fresh air integrated unit, including the frame described above, and a fresh air module and an outdoor unit module disposed on the frame. The frame includes a partition and a panel, the partition and the panel forming a first receiving cavity and a second receiving cavity. The first receiving cavity and the second receiving cavity are arranged in a vertical direction. The fresh air module and the outdoor unit module are respectively disposed in the first receiving cavity and the second receiving cavity, so that the fresh air module and the outdoor unit module are physically isolated.

[0016] Compared with the prior art, the technical solution provided in this application has the following advantages: The frame of the aforementioned integrated fresh air unit features a bend in the partition body that extends towards the outdoor unit module, forming a mounting cavity together with the main body. Filler material is placed within this cavity, creating a physical space capable of accommodating the insulation medium. This cavity forms a thermal resistance layer, effectively preventing the transfer of high-temperature heat generated by the compressor in the outdoor unit module to the fresh air module, ensuring that the intake air temperature of the fresh air module remains undisturbed. Simultaneously, this insulation structure significantly reduces the temperature difference between the two sides of the partition, preventing condensation on the partition surface due to excessive temperature differences, thus avoiding the risk of moisture or corrosion inside the unit caused by condensation dripping.

[0019] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0020] See Figure 1 and Figure 2An embodiment of this utility model provides a frame for an integrated fresh air unit, including a partition 300 disposed between a fresh air module 100 and an outdoor unit module 200. The edge of the partition 300 body is bent toward the outdoor unit module 200 to form a bent portion 310. The bent portion 310 and the partition 300 body together form a mounting cavity. The mounting cavity is filled with a filler to block the heat generated by the compressor from being transferred to the fresh air module 100 and to reduce the formation of condensate on the partition 300.

[0021] In this embodiment, the bend 310 formed by the edge of the partition 300 bending towards the outdoor unit module 200, together with the partition body, constitutes an installation cavity. A filler is placed within this cavity, creating a physical space capable of accommodating the insulation medium. The filler within this installation cavity forms a thermal resistance layer, effectively preventing the transfer of high-temperature heat generated by the compressor in the outdoor unit module 200 to the fresh air module 100, ensuring that the intake air temperature of the fresh air module 100 remains undisturbed. Simultaneously, this insulation structure significantly reduces the temperature difference between the two sides of the partition 300, preventing condensation from forming on the surface of the partition 300 due to excessive temperature differences, thereby avoiding the risk of moisture or corrosion inside the unit caused by condensate dripping.

[0022] This embodiment constructs a composite barrier that combines mechanical strength and thermal performance through the combination of the bent portion 310 and the filler. From a structural mechanics perspective, the bending design of the partition 300 edge towards the outdoor unit module 200 effectively acts as a reinforcing rib. In sheet metal processing, this bending significantly increases the bending section modulus of the partition 300 edge, preventing deformation of the partition 300 when bearing internal components or undergoing thermal expansion, thus ensuring the long-term structural stability of the frame. From a thermodynamic heat transfer mechanism perspective, the mounting cavity constructed in this embodiment is not merely a container; by introducing the filler, it artificially creates a high thermal resistance region, forcibly altering the heat flow path. Without this cavity and filler, heat would be directly conducted to the fresh air side through the metal partition 300 at an extremely high rate; however, by setting up a mounting cavity filled with heat-insulating filler, a composite sandwich structure of metal-insulation layer-metal is essentially formed. This structure plays a crucial role in preventing condensation: it ensures that the surface temperature of the partition 300 facing the fresh air module 100 is always maintained above the air dew point temperature. Especially in a humid and hot fresh air environment, if the temperature of the partition 300 is too low, moisture is easily condensed. This embodiment eliminates temperature dead zones through precise thermal bridge blocking, fundamentally solving the hidden dangers of condensation dripping causing internal circuit short circuits or bacterial growth, and significantly improving the safety and hygiene standards of the entire unit.

[0023] In one embodiment, the filler is a foam insulation board. Building upon the foregoing embodiments, this embodiment further specifies that the filler is a foam insulation board. Utilizing the microstructure of the foam material containing numerous closed pores, these pores effectively suppress air convection heat transfer, thereby providing extremely low thermal conductivity. The technical advantage of this embodiment is that, while ensuring excellent thermal insulation performance, the foam material has extremely low density, significantly reducing the overall weight of the frame. Furthermore, the foam board is easy to cut and fill, reducing the complexity of the manufacturing process and production costs, achieving a balance between lightweight and high performance.

[0024] In one embodiment, the filler is a vacuum multilayer board. This embodiment proposes another filler option: the use of a vacuum multilayer board. Vacuum multilayer boards typically consist of a porous core material and a high-barrier membrane, with an internal vacuum. The physical basis of its technical effect lies in eliminating gas convective heat transfer and gas molecule conduction heat transfer, retaining only extremely weak solid conduction and radiative heat transfer. Compared to traditional polyurethane foam or mineral wool, the thermal conductivity of vacuum multilayer boards is typically only one-tenth or even lower. In integrated unit rack designs, this means that the thickness of the mounting cavity can be compressed to the extreme while achieving the same insulation effect. This feature is extremely valuable for integrated fresh air systems that prioritize compact size: it frees up valuable internal space for duct design or filter components without sacrificing insulation performance (i.e., preventing the compressor's high temperature from affecting the fresh air), thereby indirectly improving the ventilation volume and purification efficiency of the fresh air system. Furthermore, the excellent flame-retardant properties of the vacuum multilayer board provide an additional fire safety barrier for high-temperature areas within the rack.

[0025] In one embodiment, the mounting cavity is an empty cavity, and the inner wall surface of the mounting cavity is coated with a coating. This embodiment utilizes the thermal resistance effect of the static air layer as a basic insulation method, avoiding the material costs of solid fillers. More importantly, the coating on the inner wall surface can block radiative heat transfer. This combination of air layer and functional coating can effectively reduce heat passing through the partition 300 by radiation and convection, and the structure is simpler, reducing the burden of maintenance or replacement of filler materials.

[0026] In one embodiment, the coating is hollow glass microspheres. This embodiment is a further specification of the coating material in the foregoing embodiments, limited to the use of hollow glass microspheres. Hollow glass microspheres are micron-sized hollow spheres encapsulated with a thin layer of rarefied gas. When this material is added as a filler to the coating and applied to the inner wall of the mounting cavity, countless tiny hollow spheres are densely packed within the coating, forming a complex labyrinth effect. From a heat transfer perspective, this structure produces two significant technical effects: first, the hollow structure greatly reduces the effective heat conduction path of the coating solid, providing excellent thermal insulation; second, the surface of the glass microspheres has extremely high reflectivity to infrared radiation. The heat generated by the outdoor unit compressor is often accompanied by strong thermal radiation. The hollow glass microsphere coating can reflect most of the radiant heat back to the outdoor unit side like a broken array of mirrors, preventing it from penetrating the partition 300. This dual mechanism of reflection and blocking allows this embodiment to achieve highly efficient thermal shielding without increasing the weight of the frame or occupying additional space (due to the extremely thin coating), making it particularly suitable for the inner walls of irregularly shaped mounting cavities that are difficult to fill with solid plates.

[0027] See Figure 3 and Figure 4 An embodiment of this utility model also provides a frame for an integrated fresh air unit. The frame includes a partition 300 and a panel 400. The partition 300 and the panel 400 form a first receiving cavity 500 and a second receiving cavity 600. The first receiving cavity 500 and the second receiving cavity 600 are arranged in a vertical direction. A fresh air module 100 is provided in the first receiving cavity 500, and an outdoor unit module 200 is provided in the second receiving cavity 600. The partition 300 has a mounting cavity, in which a medium is provided.

[0028] This embodiment proposes a rack design focused on spatial layout. Through the cooperation of the partition 300 and the panel 400, a first receiving cavity 500 (fresh air zone) and a second receiving cavity 600 (outdoor unit zone) arranged vertically are constructed, with the partition 300 containing a media-containing mounting cavity. The technical advantages of this design are mainly reflected in the overall thermal and humidity management and space optimization. The vertical arrangement utilizes the physical property of rising hot air, which is beneficial for heat dissipation of the outdoor unit. Simultaneously, the physical upper and lower partitions, combined with the media-containing partition 300, completely isolate the fresh air system from the outdoor unit system. This isolation ensures that the vibration, noise, and heat from the outdoor unit do not interfere with the fresh air module 100 located in the other receiving cavity, guaranteeing the cleanliness and quiet operation of the fresh air.

[0029] In one embodiment, the medium is a foam material. Similar to the previous embodiment, but in the vertical partition architecture, the foam material not only serves as insulation, but its porous structure can also absorb the vibration waves transmitted from the compressor to the partition 300 to a certain extent, thereby playing an auxiliary role in shock absorption and noise reduction, and enhancing the overall stability of the vertical structure.

[0030] In one embodiment, the inner wall of the mounting cavity is coated with a thermal insulation coating, with air as the medium. This embodiment employs a thermal insulation coating combined with an air medium. In the case of a vertical partition 300, this prevents thermal bridging caused by temperature gradients along the height direction on both sides of the partition 300. The thermal insulation coating on the inner wall protects the partition 300 substrate from long-term heat radiation and aging. Combined with the air medium, it forms a lightweight and durable thermal barrier, particularly suitable for models that are weight-sensitive but require high-strength insulation.

[0031] See Figure 4 In one embodiment, the panel 400 is provided with an access port 410 suitable for the maintenance of the compressor and electronic control components, and an access cover 420 adapted to the access port 410. This embodiment adds the technical features of the access port 410 and the access cover 420 to the structure of the panel 400. In practical applications, the compressor and electronic control components are components with relatively high failure rates and require regular inspection. The technical effect of this embodiment is to greatly improve the maintainability of the equipment. Maintenance personnel do not need to disassemble the entire large side panel 400 or damage the sealing structure; they only need to open the specific access cover 420 to directly access the core components. This not only shortens maintenance time and reduces after-sales costs, but also avoids the problem of decreased sealing caused by repeated disassembly and reassembly of the large panel 400.

[0032] See Figure 3 An embodiment of this utility model also provides a fresh air integrated unit, including the aforementioned frame, and a fresh air module 100 and an outdoor unit module 200 disposed on the frame. The frame includes a partition 300 and a panel 400, the partition 300 and the panel 400 forming a first receiving cavity 500 and a second receiving cavity 600. The first receiving cavity 500 and the second receiving cavity 600 are arranged in a vertical direction. The fresh air module 100 and the outdoor unit module 200 are respectively disposed in the first receiving cavity 500 and the second receiving cavity 600, so that the fresh air module 100 and the outdoor unit module 200 are physically isolated.

[0033] This embodiment is a comprehensive solution encompassing the aforementioned embodiments. It integrates an optimized rack structure and modular layout, placing the fresh air module 100 and the outdoor unit module 200 in vertically arranged accommodating cavities and achieving physical isolation, thus providing a highly integrated and high-performance integrated fresh air unit solution. Through the aforementioned heat-insulating cavity technology and vertical partitioning design, the entire unit achieves heat and cold decoupling and static / dynamic separation within a compact size. This effectively prevents the heat from the outdoor unit from damaging the fresh air temperature and blocks noise from entering the indoor unit, solving industry pain points such as heat cross-contamination, condensation, and excessive noise that are common in traditional integrated units.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
