Description

Technical Field

[0001] This utility model belongs to the field of refrigeration technology, specifically relating to a humidification component and a refrigeration unit. Background Technology

[0002] Refrigeration units for fresh-keeping are generally used in cold storage facilities for fruits, vegetables, and flowers to provide cooling and humidification. Preservation of some high-value fruits and flowers allows for off-peak sales and increased profits. Therefore, more and more businesses are choosing refrigeration units for fresh-keeping. Currently, most refrigeration units on the market use a combination of an evaporator and a fan, and a humidifier and a fan. This design results in large units that are inconvenient to install and use. The evaporation and humidification systems each use their own air supply system, leading to increased unit size and difficulties in installation, transportation, and operation. Since refrigeration units must be suspended from the ceiling of the cold storage facility, smaller units are easier to install and maintain. Furthermore, the additional air supply system inevitably increases the unit's operating power, leading to higher overall energy consumption. Utility Model Content

[0003] This utility model provides a humidification component and a refrigeration unit, which can solve the technical problems of conventional preservation refrigeration units, which have increased unit size and high energy consumption due to the use of two independent air supply systems.

[0004] This utility model provides a humidification component, which includes a housing and multiple wet films;

[0005] The housing has a specific air inlet, and multiple wet films are spaced apart in the housing, with the wet films being rotatably disposed.

[0006] When the wet membrane rotates to the first position, a ventilation duct is formed between adjacent wet membranes, and the air at the air inlet flows in the ventilation duct; when the wet membrane rotates to the second position, the ventilation duct is closed, and the air at the air inlet flows through the wet membrane.

[0007] In some embodiments, the wet membrane has a windward side and a leeward side. When the wet membrane is rotated to a first position, the sidewall of the wet membrane faces the air inlet, and the windward side is disposed opposite to the leeward side of the adjacent wet membrane, forming the ventilation duct between the windward side and the leeward side. When the wet membrane is rotated to a second position, the windward side faces the air inlet.

[0008] In some embodiments, a first pull rod is also included, wherein the plurality of wet films are vertically disposed in the housing, the first pull rod is connected to the top of the plurality of wet films or to the bottom of the plurality of wet films, and the first pull rod is used to pull the wet films to rotate in the horizontal direction.

[0009] In some embodiments, a connecting assembly is provided on the wet film. The connecting assembly includes a first hinge plate, a second hinge plate, and a connecting shaft. One end of the first hinge plate is connected to the outer wall of the first pull rod, and one end of the second hinge plate is connected to the wall surface of the wet film. The end of the first hinge plate opposite to the first pull rod is hinged to the end of the second hinge plate opposite to the wet film through the connecting shaft.

[0010] In some embodiments, the connecting assembly further includes a rotating shaft, one end of which is connected to the bottom end of the wet film, and the other end of which is rotatably connected to the housing.

[0011] In some embodiments, a drive assembly is also included, which includes a motor, a rack and a first rack. One end of the rack is connected to the output shaft of the motor, and the other end of the rack is provided with a first meshing tooth. One end of the first rack meshes with the first meshing tooth, and the other end of the first rack is connected to the end of the first pull rod away from the wet film.

[0012] In some embodiments, a second pull rod is also included, wherein the first pull rod is connected to the bottom of the wet film and the second pull rod is connected to the top of the wet film. The drive assembly also includes a second rack, which extends along the height direction of the wet film. The rack is also provided with a second meshing tooth. One end of the second rack meshes with the second meshing tooth, and the other end of the second rack is connected to the end of the second pull rod away from the wet film.

[0013] In some embodiments, the top of the housing is provided with a water inlet and a water distribution pipe, the water distribution pipe is connected to the water inlet, and the water distribution pipe is provided with a plurality of water distribution outlets, the water distribution outlets facing the wet membrane.

[0014] A refrigeration unit includes a humidifier, a fan, and an evaporator. The humidifier is the humidifier described above. The humidifier, the fan, and the evaporator are arranged sequentially in the air supply path at the air inlet.

[0015] In some embodiments, when the refrigeration unit is in cooling mode, the wet film rotates to the first position, and the air at the air inlet flows sequentially through the ventilation duct, the fan, and the evaporator; when the refrigeration unit is in humidification mode, the wet film rotates to the second position, and the air at the air inlet flows sequentially through the wet film and the fan.

[0016] The humidification component and refrigeration unit provided by this utility model have the following beneficial effects:

[0017] In this invention, the humidifier's operating state can be flexibly controlled by rotating the wet film. When the wet film rotates to the first position, the ventilation duct is open, and air does not flow through the wet film, thus achieving no humidification. When the wet film rotates to the second position, the ventilation duct is closed, and air must flow through the wet film, thus achieving humidification. This setting allows for flexible switching of humidification states according to actual needs, avoiding unnecessary humidification operations and saving energy. In humidification mode, air must flow through the wet film, increasing the contact area between the air and the wet film, allowing for more effective absorption of moisture and improving humidification efficiency. The rotation of the wet film ensures that the air absorbs moisture more evenly as it flows through the film, avoiding uneven humidification in certain areas and improving the uniformity of the humidification effect. In non-humidification mode, air does not flow through the wet film, preventing it from becoming over-wet when humidification is not needed. Over-wetting can lead to the growth of bacteria and mold on the surface of the wet film, affecting its lifespan and humidification effect. By reducing over-wetting of the wet film, its lifespan can be extended. The rotatable wet film design reduces the space occupied by the ventilation duct, making the humidifier more compact. This compact design helps reduce component size, making it more suitable for installation in space-constrained cold storage rooms, optimizing space utilization. In non-humidifying mode, air flows through the ventilation duct with low resistance, reducing airflow resistance and improving airflow efficiency, thereby reducing the unit's operating power. The rotatable wet film design allows the humidifier to better adapt to different environmental conditions. Whether in high or low humidity environments, the optimal humidification effect can be achieved by adjusting the position of the wet film, improving the equipment's adaptability and versatility.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0027] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used here to describe the spatial positional relationship of a device or feature as shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device as described in the figure. For example, if a device in the figure is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures.

[0028] See also Figures 1 to 4As shown, according to an embodiment of the present invention, a humidification component is provided, which includes a housing 1 and a plurality of wet membranes 2; the housing 1 has an air inlet 101, and the plurality of wet membranes 2 are spaced apart in the housing 1 and are rotatably disposed; when the wet membranes 2 are rotated to a first position, a ventilation duct 201 is formed between adjacent wet membranes 2, and the air at the air inlet 101 flows in the ventilation duct 201; when the wet membranes 2 are rotated to a second position, the ventilation duct 201 is closed, and the air at the air inlet 101 flows through the wet membranes 2.

[0029] Specifically, when the unit does not need to humidify the circulating air, the wet membrane 2 rotates to the first position. At this time, ventilation ducts 201 are formed between the multiple wet membranes 2. These ventilation ducts 201 are channels for airflow, allowing the air to flow smoothly through them without contacting the wet membranes 2. After the air enters the housing 1 from the air inlet 101, it flows directly through the ventilation ducts 201 to the next component. During this process, the air does not pass through the wet membranes 2 and is therefore not humidified. When the unit needs to humidify the circulating air, the wet membranes 2 rotate to the second position. At this time, the distance between the wet membranes 2 decreases, and the ventilation ducts 201 are closed. This means that the air cannot flow through the ventilation ducts 201 but must flow through the wet membranes 2. After the air enters the housing 1 from the air inlet 101, because the ventilation ducts 201 are closed, the air can only flow through the wet membranes 2. During the flow through the wet membranes 2, the air comes into contact with the surface of the wet membranes 2, thereby absorbing the moisture on the wet membranes 2 and achieving humidification.

[0030] In this embodiment, the humidification component is specifically a humidifier. The operating state of the humidifier can be flexibly controlled by rotating the wet membrane 2. When the wet membrane 2 rotates to the first position, the ventilation duct 201 opens, and air does not flow through the wet membrane 2, thus achieving no humidification. When the wet membrane 2 rotates to the second position, the ventilation duct 201 closes, and air must flow through the wet membrane 2, thus achieving humidification. This setting allows for flexible switching of the humidification state according to actual needs, avoiding unnecessary humidification operations and saving energy. In humidification mode, air must flow through the wet membrane 2, increasing the contact area between the air and the wet membrane 2, allowing for more effective absorption of moisture and improving humidification efficiency. The rotation of the wet membrane 2 ensures that the air absorbs moisture more evenly as it flows through it, avoiding uneven humidification in certain areas and improving the uniformity of the humidification effect. In non-humidification mode, air does not flow through the wet membrane 2, preventing it from becoming overly moist when humidification is not needed. Over-moistening can lead to the growth of bacteria and mold on the surface of the wet membrane 2, affecting its lifespan and humidification effect. By reducing excessive wetting of the wet film 2, its service life can be extended. The rotatable design of the wet film 2 reduces the space occupied by the ventilation duct 201, making the humidifier more compact. This compact design helps reduce component size, making it more suitable for installation in space-constrained cold storage rooms, optimizing space utilization. In non-humidifying mode, air flows through the ventilation duct 201 with low resistance, reducing airflow resistance and improving airflow efficiency, thereby reducing the unit's operating power. The rotatable wet film 2 design allows the humidifier to better adapt to different environmental conditions. Whether in high or low humidity environments, the optimal humidification effect can be achieved by adjusting the position of the wet film 2, improving the equipment's adaptability and versatility.

[0031] In this embodiment, in humidification mode, air must flow through the wet membrane 2, increasing the contact area between the air and the wet membrane 2. This allows for more effective absorption of moisture, thereby improving humidification efficiency. By controlling the position of the wet membrane 2, humidification can be flexibly adjusted, avoiding unnecessary humidification operations and saving energy. Because the number of air supply systems is reduced, the unit size can be made smaller, facilitating installation and transportation. The reduced number of components simplifies the unit's structure and lowers the complexity of installation and maintenance. In non-humidification mode, air does not flow through the wet membrane 2, preventing it from becoming over-wet when humidification is not needed. This reduces wear and tear on the wet membrane 2 and extends its service life. The reduced number of air supply systems also reduces the frequency of use of related components, thus minimizing component wear.

[0032] As a specific implementation method, this embodiment uses an automatic control system to automatically determine whether humidification is needed based on the humidity value detected by the humidity sensor inside the cold storage, and controls the rotation position of the wet film 2. This automatic control method improves the intelligence of the unit, enabling flexible adjustment of the humidification state according to actual needs. By precisely controlling the humidification state, the humidity environment inside the cold storage can be better maintained.

[0033] See also Figures 1 to 4 As shown, the wet membrane 2 has a windward side 21 and a leeward side 22. When the wet membrane 2 is rotated to the first position, the sidewall of the wet membrane 2 faces the air inlet 101, and the windward side 21 is arranged opposite to the leeward side 22 of the adjacent wet membrane 2, forming a ventilation duct 201 between the windward side 21 and the leeward side 22. When the wet membrane 2 is rotated to the second position, the windward side 21 faces the air inlet 101.

[0034] Specifically, when the circulating air does not require humidification, the wet membrane 2 rotates to the first position. At this time, the sidewall of the wet membrane 2 faces the air inlet 101, and the windward side 21 is set opposite to the leeward side 22 of the adjacent wet membrane 2. A ventilation duct 201 is formed between the windward side 21 and the leeward side 22. These ventilation ducts 201 are channels for airflow, and the air can flow smoothly through these channels without contacting the wet membrane 2. After the air enters the housing 1 from the air inlet 101, it flows directly through the ventilation duct 201 to the next component. During this process, the air does not pass through the wet membrane 2 and therefore is not humidified. When the circulating air needs humidification, the wet membrane 2 rotates to the second position. At this time, the windward side 21 faces the air inlet 101. Because the windward side 21 faces the air inlet 101, the distance between adjacent wet membranes 2 becomes smaller, and the ventilation duct 201 is closed. This means that the air cannot flow through the ventilation duct 201 and must flow through the wet membrane 2. After the air enters the housing 1 from the air inlet 101, because the ventilation duct 201 is closed, the air can only flow through the windward side 21 of the wet membrane 2. During the flow through the wet membrane 2, the air will come into contact with the surface of the wet membrane 2, thereby absorbing the moisture on the wet membrane 2, thus achieving humidification. The humidified air then flows into the next component to complete the humidification process. The rotation speed of the wet membrane 2 can be adjusted according to actual needs, allowing for rapid switching between humidification and non-humidification, avoiding excessive impact on the operation of the unit.

[0035] In this embodiment, when the wet membrane 2 rotates to the first position, its sidewall faces the air inlet 101, and its windward side 21 is positioned opposite the leeward side 22 of the adjacent wet membrane 2. At this time, a ventilation duct 201 is formed between the windward side 21 and the leeward side 22. This arrangement results in lower airflow resistance and lower unit operating power, saving energy. Simultaneously, the air does not contact the wet membrane 2, preventing over-wetting when humidification is not needed and extending its service life. When the wet membrane 2 rotates to the second position, its windward side 21 faces the air inlet 101. At this time, the distance between adjacent wet membranes 2 decreases, and the ventilation duct 201 is closed. This arrangement effectively humidifies the circulating air when humidification is needed, increasing air humidity. Furthermore, humidification can be controlled by adjusting the position of the wet membrane 2, offering flexible operation and allowing adjustments based on actual needs. The rotatable wet membrane 2 design reduces the need for additional valves or other control components, further simplifying the humidifier's structure and reducing the number of components.

[0036] See also Figures 1 to 4 As shown, it also includes a first pull rod 3. Multiple wet films 2 are vertically arranged in the housing 1. The first pull rod 3 is connected to the top or bottom of the multiple wet films 2. The first pull rod 3 is horizontally arranged and is used to pull the wet films 2 to rotate in the horizontal direction. In this embodiment, the first pull rod 3 can be manually operated or automatically driven by a drive system.

[0037] Specifically, in non-humidification mode, the first lever 3 pulls the wet membrane 2 towards the air inlet 101. After rotation, the lever holds the wet membrane 2 in the first position, with its sidewall facing the air inlet 101. The windward side 21 is positioned opposite the leeward side 22 of the adjacent wet membrane 2, forming a ventilation duct 201 between them. These ventilation ducts 201 are channels for airflow, allowing air to flow smoothly without contacting the wet membrane 2. In humidification mode, the wet membrane 2 rotates to the second position. At this time, the windward side 21 faces the air inlet 101. Because the windward side 21 faces the air inlet 101, the distance between adjacent wet membranes 2 decreases, and the ventilation duct 201 is closed. This means that air cannot flow through the ventilation duct 201 but must flow through the wet membrane 2. In humidification mode, the first lever 3 pulls the wet membrane 2 to the second position, ensuring that the windward side 21 faces the air inlet 101. The first lever 3, through horizontal pulling force, keeps the wet membrane 2 in a stable position, ensuring that airflow must pass through the wet membrane 2, thus achieving humidification. The first lever 3, through horizontal pulling force, drives the wet membrane 2 to rotate horizontally. When switching from non-humidification mode to humidification mode, the first lever 3 pulls the wet membrane 2 to the second position; when switching from humidification mode to non-humidification mode, the first lever 3 pulls the wet membrane 2 to the first position. The pulling speed of the first lever 3 can be adjusted according to actual needs. Generally, the switching speed should be fast enough to ensure rapid switching when humidification or non-humidification is needed, avoiding excessive impact on the unit's operation.

[0038] In this embodiment, in humidification mode, the first pull rod 3 ensures that the windward side 21 of the wet membrane 2 faces the air inlet 101 through horizontal pulling force, and the air must flow through the wet membrane 2. In non-humidification mode, the first pull rod 3 ensures that the side wall of the wet membrane 2 faces the air inlet 101, forming a ventilation duct 201. This setting can prevent the wet membrane 2 from shifting due to wind pressure or other external forces, thereby ensuring the stable operation of the humidifier. The pulling force of the first pull rod 3 can reduce the vibration of the wet membrane 2 during operation and improve the stability and reliability of the equipment. The first lever 3 can precisely control the position of the wet film 2, allowing it to flexibly switch between the first position (non-humidification mode) and the second position (humidification mode). This precise control enables the humidifier to quickly adjust its working state according to actual needs. The first lever 3 ensures that the wet film 2 remains stable in different positions through horizontal pulling force, which can prevent the wet film 2 from shifting due to wind pressure or other external forces, thereby ensuring the stable operation of the humidifier. By simplifying the structure and reducing additional control components, the setting of the first lever 3 reduces the number of failure points and improves the reliability and stability of the equipment.

[0039] See also Figures 1 to 4As shown, a connecting assembly 4 is provided on the wet membrane 2. The connecting assembly 4 includes a first hinge plate 401, a second hinge plate 402, and a connecting shaft 403. One end of the first hinge plate 401 is connected to the outer wall of the first pull rod 3, and one end of the second hinge plate 402 is connected to the wall surface (leeward side 22) of the wet membrane 2. The end of the first hinge plate 401 away from the first pull rod 3 is hinged to the end of the second hinge plate 402 away from the wet membrane 2 through the connecting shaft 403.

[0040] Specifically, one end of the first hinge plate 401 is connected to the outer wall of the first pull rod 3, and the other end is hinged to the second hinge plate 402 through the connecting shaft 403. One end of the second hinge plate 402 is connected to the wall of the wet film 2, and the other end is hinged to the first hinge plate 401 through the connecting shaft 403. The first hinge plate 401 and the second hinge plate 402 are connected, allowing relative rotation between them. In the non-humidification mode, the first pull rod 3 holds the wet film 2 in the first position through the connecting component 4 to ensure that the ventilation duct 201 is unobstructed. The hinge setting of the connecting component 4 allows the wet film 2 to rotate flexibly when needed. In the humidification mode, the first pull rod 3 pulls the wet film 2 to the second position through the connecting component 4 to ensure that the windward surface 21 faces the air inlet 101. The first pull rod 3, through horizontal pulling force, drives the connecting assembly 4 (first hinge plate 401 and second hinge plate 402) to move, thereby causing the wet film 2 to rotate in the horizontal direction. The first pull rod 3 pulls the first hinge plate 401, and through the hinge action of the connecting shaft 403, drives the second hinge plate 402 and the wet film 2 to rotate to the second position. The first pull rod 3 pulls the first hinge plate 401, and through the hinge action of the connecting shaft 403, drives the second hinge plate 402 and the wet film 2 to rotate to the first position.

[0041] In this embodiment, the hinged arrangement of the connecting component 4 allows the wet membrane 2 to rotate flexibly in the horizontal direction, ensuring that the wet membrane 2 can smoothly switch between the first position and the second position. The first hinge plate 401 and the second hinge plate 402 are hinged through the connecting shaft 403, ensuring that the wet membrane 2 remains stable in different positions and preventing the wet membrane 2 from shifting due to wind pressure or other external forces. The hinged arrangement reduces direct friction between components, extends the service life of the connecting component 4, and reduces maintenance costs. Moreover, by enabling the rotation of the wet membrane 2 through the connecting component 4, the use of additional drive devices or control components is reduced, further simplifying the structure of the humidifier and reducing the number of components. Through the connecting component 4, the first pull rod 3 can precisely control the position of the wet membrane 2, realizing rapid switching between humidification and non-humidification modes. In humidification mode, the air must flow through the wet membrane 2, increasing the contact area between the air and the wet membrane 2 and improving humidification efficiency. In non-humidification mode, the air does not flow through the wet membrane 2, avoiding over-wetting of the wet membrane 2 when humidification is not needed, thus extending the service life of the wet membrane 2. Simultaneously, a first pull rod 3 and a connecting component 4 are installed. The first pull rod 3 precisely controls the position of the wet film 2 through the connecting component 4, ensuring that the humidifier can quickly switch between different modes. The hinged design of the connecting component 4 ensures that the wet film 2 remains stable in different positions, reducing external interference and improving the operational stability of the equipment. Through the connecting component 4, the operation of the first pull rod 3 is simpler, reducing the complexity of maintenance and cleaning, and improving the ease of use of the equipment. Through the synergistic effect of the first pull rod 3 and the connecting component 4, flexible control and stable operation of the wet film 2 are achieved, effectively improving the performance and reliability of the humidifier.

[0042] In one specific implementation, one end of the first hinge plate 401 is riveted to the outer wall of the first pull rod 3 by a pin, and one end of the second hinge plate 402 is riveted to the wall (leeward side 22) of the wet film 2 by a pin.

[0043] See also Figures 1 to 4 As shown, the connecting assembly 4 also includes a rotating shaft 404. One end of the rotating shaft 404 is connected to the bottom end of the wet film 2, and the other end of the rotating shaft 404 is rotatably connected to the housing 1. In order to ensure that the connecting assembly 4 can drive the wet film 2 to rotate, the rotating shaft 404 provides a constraint force.

[0044] In this embodiment, one end of the rotating shaft 404 is connected to the bottom end of the wet membrane 2, and the other end is rotatably connected to the housing 1. This configuration provides a stable support point for the wet membrane 2, ensuring that the wet membrane 2 will not undergo unnecessary displacement or vibration due to external forces during operation. The fixing effect of the rotating shaft 404 can effectively reduce the shaking of the wet membrane 2 during operation and improve the operational stability of the equipment. Especially in humidification mode, when the airflow passes through the wet membrane 2, a certain wind pressure is generated. The rotating shaft 404 can ensure that the wet membrane 2 maintains a stable position and avoids displacement caused by wind pressure. The rotating shaft 404 provides a constraint force to ensure that the wet membrane 2 can rotate smoothly along a predetermined axis during rotation. This constraint force makes the rotation of the wet membrane 2 more precise and avoids mechanical wear or failure caused by unstable rotation. Through the constraint of the rotating shaft 404, the rotation of the wet membrane 2 is smoother, reducing direct friction between components, extending the service life of the wet membrane 2 and the connecting assembly 4, and reducing maintenance costs. The rotating shaft 404 reduces potential failure points caused by unstable positioning of the wet film 2, improving the reliability and stability of the equipment. Stable support and constraint reduce safety hazards during operation, enhancing overall equipment safety. The stable rotation of the wet film 2 via the rotating shaft 404 reduces the need for additional support components or fixing devices, further simplifying the humidifier's structure and reducing the number of parts.

[0045] It is worth noting that the thickness of the wet film 2 is relatively thin. Therefore, when selecting the rotating shaft 404, a small rotating shaft 404 should be selected accordingly. It is necessary to ensure that the rotating shaft 404 can enable the wet film 2 to rotate relative to the shell 1 without affecting the structural strength of the wet film 2, so as to play a certain constraining role on the wet film 2.

[0046] See also Figures 1 to 4 As shown, it also includes a drive assembly 5, which includes a motor 501, a rack 502 and a first rack 503. One end of the rack 502 is connected to the output shaft of the motor 501, and the other end of the rack 502 is provided with a first meshing tooth. One end of the first rack 503 meshes with the first meshing tooth, and the other end of the first rack 503 is connected to the end of the first pull rod 3 away from the wet film 2.

[0047] Specifically, the output shaft of motor 501 is connected to one end of rack 502 to provide power. The other end of rack 502 is provided with a first meshing tooth. One end of first rack 503 meshes with the first meshing tooth, and the other end is connected to the end of first pull rod 3 away from wet film 2. In humidification mode, motor 501 drives first pull rod 3 through rack 502 and rack 503 to pull wet film 2 to the second position, ensuring that the windward surface 21 faces air inlet 101. Motor 501 drives first pull rod 3 through rack 502 and rack 503, thereby causing wet film 2 to rotate in the horizontal direction. When motor 501 starts, it drives first pull rod 3 through rack 502 and rack 503 to pull wet film 2 from the first position to the second position. When motor 501 starts in reverse, it drives first pull rod 3 through rack 502 and rack 503 to pull wet film 2 from the second position to the first position.

[0048] In this embodiment, the motor 501 precisely controls the movement of the first pull rod 3 through the rack 502 and the first gear 503, thereby driving the wet film 2 to switch between different positions. Combined with the automatic control system, the motor 501 can automatically adjust the position of the wet film 2 according to the feedback from the humidity sensor, realizing automated control, reducing manual intervention, and improving operating efficiency. The meshing arrangement of the rack 502 and the first gear 503 reduces direct friction between components, extends the service life of the drive assembly 5, and reduces maintenance costs. The rotation of the wet film 2 is achieved through the motor 501, rack 502, and first gear 503, reducing the use of additional drive devices or control components, further simplifying the structure of the humidifier and reducing the number of components. The drive assembly 5 and the connecting assembly 4 work together. The motor 501 precisely controls the movement of the first pull rod 3 through the rack 502 and the first gear 503, thereby driving the wet film 2 to switch between different positions. The connecting assembly 4 (including the first hinge plate 401, the second hinge plate 402 and the connecting shaft 403) ensures that the wet film 2 remains stable in different positions, reduces external interference, and improves the operational stability of the equipment. Through the synergistic effect of the drive assembly 5 and the connecting assembly 4, the rotation operation of the wet film 2 is simpler, reducing the complexity of maintenance and cleaning, and improving the ease of use of the equipment.

[0049] See also Figures 1 to 4 As shown, it also includes a second pull rod 6. The first pull rod 3 is connected to the bottom of the wet film 2, and the second pull rod 6 is connected to the top of the wet film 2. The drive assembly 5 also includes a second rack 505. The rack 502 extends along the height direction of the wet film 2. The rack 502 is also provided with a second meshing tooth. One end of the first rack 503 meshes with the second meshing tooth, and the other end of the first rack 503 is connected to the end of the second pull rod 6 away from the wet film 2. Correspondingly, the top of the wet film 2 is also provided with a rotating shaft 404.

[0050] In this embodiment, the first pull rod 3 is connected to the bottom of the wet membrane 2, and the second pull rod 6 is connected to the top of the wet membrane 2. This double pull rod arrangement can distribute the tension more evenly, reducing the swaying and deformation of the wet membrane 2 during rotation. With the simultaneous action of the first pull rod 3 and the second pull rod 6, the wet membrane 2 is subjected to more even force during rotation, reducing stress concentration caused by single-point force, thereby extending the service life of the wet membrane 2. The rack 502 is provided with a first meshing tooth and a second meshing tooth. The first rack 503 meshes with the first meshing tooth, and the second rack 505 meshes with the second meshing tooth. This double rack drive mechanism can more accurately control the rotation position of the wet membrane 2. The double rack drive can reduce the errors that may be caused by the single rack drive, ensuring that the wet membrane 2 remains stable in different positions and improving the operating accuracy of the equipment. The double rack and pinion configuration reduces the load on individual components, thereby reducing wear and extending the equipment's lifespan. More stable rotation control reduces safety hazards during operation, improving overall safety. The double rack drive allows for faster switching of the wet film 2 between different positions, increasing response speed and reducing energy consumption during mode switching. Motor 501 drives the first pull rod 3 via rack 502 and first rack 503, and simultaneously drives the second pull rod 6 via second rack 505, precisely controlling the position of the wet film 2 and enabling rapid switching between humidification and non-humidification modes. The double pull rod and double rack configuration ensures the wet film 2 remains stable in different positions, reducing external interference and improving operational stability. The synergistic effect of the double pull rod and double rack simplifies the rotation of the wet film 2, reducing maintenance and cleaning complexity and improving ease of use.

[0051] See also Figures 1 to 4 As shown, the top of the housing 1 is provided with a water inlet 102 and a water distribution pipe 103. The water distribution pipe 103 is connected to the water inlet 102. The water distribution pipe 103 is provided with multiple water distribution ports, which face the wet film 2.

[0052] Specifically, water enters the water distribution pipe 103 at the top of the housing 1 through the water inlet 102. The water distribution pipe 103 is connected to the water inlet 102 and is responsible for evenly distributing the water to each water outlet. Multiple water outlets are provided on the water distribution pipe 103, facing the wet membrane 2 to ensure that the water can be sprayed evenly onto the wet membrane 2. The wet membrane 2 rotates to the second position, at which point the windward side 21 faces the air inlet 101. Water enters the water distribution pipe 103 from the water inlet 102 and is evenly sprayed onto the wet membrane 2 through the water outlets. After absorbing moisture, the wet membrane 2 becomes humid. After air enters the housing 1 from the air inlet 101, since the ventilation duct 201 is closed, the air can only flow through the wet membrane 2. During the flow through the wet membrane 2, the air comes into contact with the surface of the wet membrane 2, thereby absorbing the moisture on the wet membrane 2, achieving humidification. The humidified air then flows into the next component, completing the humidification process.

[0053] In this embodiment, the water inlet 102, acting as the water inlet, introduces water into the distribution pipe 103. It ensures that water can smoothly enter the system and is the starting point of the entire humidification process. The distribution pipe 103 connects the water inlet 102 and multiple distribution outlets, its function being to evenly distribute water to each outlet. The design of the distribution pipe 103 typically considers the uniformity of water flow to ensure consistent water output from each outlet. The distribution outlets are the ends of the distribution pipe 103, directly facing the wet film 2. They evenly spray moisture onto the wet film 2, ensuring that every part of the wet film 2 is adequately wetted. This uniform wetting is crucial for improving humidification efficiency. Water can be evenly sprayed onto the wet membrane 2 through the water distribution pipe 103 and multiple water outlets, ensuring that the wet membrane 2 can absorb water evenly in humidification mode. The evenly moistened wet membrane 2 can more effectively contact the air and absorb moisture, thereby improving humidification efficiency. The evenly moistened wet membrane 2 also ensures that the contact area between the air and the wet membrane 2 is maximized when the air flows through the wet membrane 2, thereby improving the humidification effect. The design of the water inlet 102 and the water distribution pipe 103 ensures that water can be sprayed onto the wet membrane 2 quickly and evenly, reducing the wetting time and improving the response speed of the equipment.

[0054] See also Figures 1 to 5 As shown, a refrigeration unit includes a humidifier, a fan 7 and an evaporator 8, characterized in that the humidifier is the aforementioned humidifier, and the humidifier, fan 7 and evaporator 8 are arranged sequentially on the air supply path of the air inlet 101.

[0055] Specifically, in humidification mode, the wet film 2 rotates to the second position, with its windward side 21 facing the air inlet 101. Water enters the water distribution pipe 103 from the water inlet 102 and is evenly sprayed onto the wet film 2 through the water distribution pipe, thus moistening the wet film 2. After the air enters the humidifier, it flows through the moist wet film 2 and absorbs the moisture on the wet film 2, achieving humidification. The humidified air continues to flow to the next component and enters the fan 7. The fan 7 generates negative pressure by rotating, accelerating the airflow. At this time, the evaporator 8 does not work, and the humidified air is directly sent out. When humidification is not required, the wet film 2 rotates to the first position, with its sidewall facing the air inlet 101. The windward side 21 is positioned opposite the leeward side 22 of the adjacent wet film 2, forming a ventilation duct 201 between the windward side 21 and the leeward side 22. After the air enters the humidifier, it passes directly through the ventilation duct 201 without contacting the wet film 2, thus not humidifying. The air continues to flow to the next component. The unhumidified air enters the fan 7, which generates negative pressure by rotating, accelerating the airflow and ensuring that the air can flow smoothly to the evaporator 8. The refrigerant inside the evaporator 8 circulates continuously through the refrigeration cycle system, absorbing heat from the air and cooling it.

[0056] In this embodiment, the position of the wet film 2 can be flexibly changed between humidification and non-humidification modes. In humidification mode, the wet film 2 is moistened, and air flowing through it absorbs moisture, achieving humidification. In non-humidification mode, air passes through the ventilation duct 201 and does not come into contact with the wet film 2, avoiding unnecessary humidification. In non-humidification mode, air is accelerated by the fan 7 and enters the evaporator 8, where the refrigerant absorbs heat from the air through the refrigeration cycle system, achieving cooling. This setup ensures the independence and high efficiency of the cooling and humidification functions. In humidification mode, the evaporator 8 can remain inactive, reducing unnecessary energy consumption. The evaporator 8 only activates when cooling is needed, thereby reducing overall operating power and saving energy. By uniformly wetting the wet film 2, the growth of bacteria and mold is reduced, improving air quality. Simultaneously, it reduces wear and maintenance costs of the wet film 2, minimizing environmental impact. The humidifier, fan 7, and evaporator 8 are arranged sequentially on the air supply path. The overall arrangement is compact, reducing the equipment's footprint and making it suitable for installation in cold storage rooms with limited space. By simplifying the structure, additional control components and drive devices are reduced, lowering the points of failure and improving the equipment's reliability and stability.

[0057] See also Figures 1 to 5 When the refrigeration unit is in cooling mode, the wet film 2 rotates to the first position, and the air at the air inlet 101 flows through the ventilation duct 201, the fan 7 and the evaporator 8 in sequence; when the refrigeration unit is in humidification mode, the wet film 2 rotates to the second position, and the air at the air inlet 101 flows through the wet film 2 and the fan 7 in sequence.

[0058] In this embodiment, the evaporator 8 operates while the humidifier does not in cooling mode, reducing unnecessary energy consumption. Conversely, the evaporator 8 operates while the humidifier does, further reducing the energy consumption of the refrigeration system. By rationally allocating operating states, unnecessary energy consumption is reduced, lowering operating costs. Uniform wetting of the wet film 2 reduces the growth of bacteria and mold, improving air quality. Simultaneously, it reduces wear and maintenance costs of the wet film 2, minimizing environmental impact. This configuration, through rational control of the wet film 2's position, allows the refrigeration unit to flexibly switch between cooling and humidification modes, while optimizing the airflow path and improving the overall system efficiency and performance. This configuration, through the synergistic action of the humidifier, fan 7, and evaporator 8, achieves highly efficient cooling and humidification functions.
