[0002] Red wine storage generally requires a suitable humidity range for optimal results. Too low humidity will cause the cork to dry out, affecting the seal and allowing more air to contact the wine, accelerating oxidation and leading to a decline in quality.

[0055] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0056] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and 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. Therefore, they should not be construed as limiting this invention.

[0057] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0058] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0059] In related technologies, the ambient temperature of the refrigeration equipment is high (e.g., external temperature above 35°C), while the internal temperature is set relatively low (e.g., 5°C). Therefore, the compressor needs to be turned on frequently or for extended periods to provide cooling. However, air-cooled refrigeration causes moisture condensation, resulting in a significant decrease in humidity inside the refrigeration equipment. When the refrigeration equipment needs to maintain a high humidity level (e.g., 80%), the humidification components in related technologies are insufficient to meet the humidification requirements, thus necessitating improvements in humidification efficiency.

[0060] The following reference Figures 1 to 5 The diagram illustrates how the humidification component 100 and the refrigeration device of this embodiment solve the above-mentioned problems.

[0061] Reference Figure 1 and Figure 2 As shown, it can be understood that the humidification component 100 of the first aspect embodiment of the present invention includes a water storage component 410 and a first fan 401. The water storage component 410 can store liquid, and the first fan 401 generates a conveying airflow. The air outlet of the first fan 401 faces the water storage component 410, so that the conveying airflow passes through the water storage component 410 to remove the moisture in the water storage component 410, thereby forming high humidity air, which enters the target space and mixes with the air in the target space to increase the humidity of the target space.

[0062] Understandably, due to the limited space within the refrigeration equipment, the installation space for the humidification component 100 is relatively small to avoid affecting usability, thus limiting the power of the first fan 401. When faced with high-temperature external environments and low-temperature storage requirements, leading to increased moisture loss, and also requiring high-humidity storage conditions, the combination of the first fan 401 and the water storage unit 410 alone results in low humidification efficiency, making it difficult to meet the aforementioned requirements.

[0063] Reference Figure 1 and Figure 2As shown, it can be understood that the humidification assembly 100 of the first aspect embodiment of the present invention further includes an ultrasonic generator 406 and a water guide 407. The water guide 407 connects the ultrasonic generator 406 and the water storage unit 410 to transfer water from the water storage unit 410 to the ultrasonic generator 406. The water guide 407 can be a device with water guiding function, such as a cotton swab. The ultrasonic generator 406 emits waveforms through vibration, causing liquid water to transform into tiny water mist particles. These tiny water mist particles are then blown into the air by the first fan 401, thereby achieving the humidification effect.

[0064] Specifically, the humidification assembly 100 includes a housing 402 and a cover plate 408. The housing 402 has a first mounting groove 403 and a second mounting groove 404. A spacer 405 is provided between the first mounting groove 403 and the second mounting groove 404, located at the bottom of both grooves, preventing communication between their bottoms but allowing communication between their tops. A first fan 401 is disposed in the first mounting groove 403, and liquid is stored in the second mounting groove 404 to form a water reservoir 410. The airflow from the first fan 401 enters the second mounting groove 404 from above the spacer 405, contacting the liquid and removing moisture, thus creating highly humid air. The cover plate 408 is connected to the housing 402 and located above the first mounting groove 403 and the second mounting groove 404. A gap exists between the cover plate 408 and the liquid surface to form a humidification channel. A first air outlet 104 is provided on the cover plate 408, from which highly humid air flows out. When the first fan 401 is powered on, relatively dry air is drawn into the fan and accelerated. The dry air then quickly passes over the liquid surface, while the more humid air on the liquid surface is quickly carried out through the first air outlet 104 on the cover plate 408 to the target space to mix with the air, thereby increasing the relative humidity of the target space. When the ultrasonic generator 406 is turned on, it can further increase the air humidity, and under the action of the airflow blown out by the first fan 401, it can accelerate the mixing with the air in the target space, thereby improving the humidification efficiency.

[0065] Understandably, the ultrasonic generator 406 is mounted on the cover plate 408, which has a humidification hole 409. Water mist particles generated by the vibration of the ultrasonic generator 406 can enter the target space through the humidification hole 409, shortening the transport distance. Furthermore, the humidification hole 409 is close to the first air outlet 104, allowing the airflow from the first fan 401 to accelerate the mixing rate of the water mist particles with the air in the target space. Since the ultrasonic generator 406 is integrated into the cover plate 408, the space occupied by the humidification assembly 100 is reduced. That is, the ultrasonic generator 406 and the water guide 407 are positioned between the cover plate 408 and the housing 402, utilizing the existing space of the humidification assembly 100. Without increasing the space occupied by the humidification assembly 100, the overall humidification efficiency of the humidification assembly 100 is increased, better meeting the requirements of refrigeration equipment for setting low temperature and high humidity in high ambient temperatures.

[0066] Reference Figure 1 and Figure 2 As shown, it can be understood that the cover plate 408 includes an air outlet area, the first air outlet 104 is located in the air outlet area, the first fan 401 is located on one side of the air outlet area, and the ultrasonic generator 406 is located on the other side of the air outlet area. That is, the airflow blown out by the first fan 401 first passes through the first air outlet 104 and is not blocked by the ultrasonic generator 406 and the water guide 407, so as to avoid the ultrasonic generator 406 and the water guide 407 affecting the humidification efficiency of the first fan 401 and the water storage device 410.

[0067] Reference Figures 3 to 5 As shown, it can be understood that the refrigeration device of the second aspect embodiment of the present invention can specifically be a refrigerator, wine cabinet, or other products. The refrigeration device includes a cabinet 101, a refrigeration component, and a humidification component 100 according to the first aspect embodiment of the present invention. The cabinet 101 has a storage compartment and an air supply duct 201 for supplying airflow to the storage compartment. The refrigeration component is used to provide a refrigeration environment for the storage compartment. The refrigeration component includes an evaporator 301 and a compressor, configured to controllably generate a cooling airflow and cause the cooling airflow to be delivered to the storage compartment through the air supply duct 201. That is, the refrigeration component is used to refrigerate the storage compartment. The humidification component 100 is disposed in the cabinet 101 and configured to controllably generate a high-humidity airflow and deliver the high-humidity airflow to the air supply duct 201 so that the high-humidity airflow flows into the storage compartment along with the cooling airflow. It can be understood that the high-humidity airflow has a high moisture content, which can increase the humidity in the storage compartment.

[0068] Reference Figure 4 and Figure 5As shown, the air supply duct 201 includes a second air outlet 202 and a return air outlet 302 connecting the storage room. The second air outlet 202 is located at the top of the storage room, and the return air outlet 302 is located at the bottom of the storage room. The refrigeration equipment includes a second fan for circulating air between the storage room and the air supply duct 201. The first air outlet 104 is located near the return air outlet 302, that is, the first air outlet 104 is located on the side of the cabinet 101 near the return air outlet 302, for example, the first air outlet 104 is located directly below the return air outlet 302, or the first air outlet 104 is located diagonally below the return air outlet 302. When both the second fan and the humidification component 100 are in operation, the high-humidity airflow generated by the humidification component 100 is sent to the air supply duct 201 through the return air outlet 302 and enters the storage room through the second air outlet 202. After being accelerated a second time by the second fan, the high-humidity airflow comes out from the second air outlet 202 and mixes more thoroughly with the air in the storage room, thereby further improving the humidification efficiency.

[0069] For example, refer to Figure 3 As shown, the cabinet 101 includes a shelf 103, on which a humidifying component 100 is mounted. The cabinet 101 has an opening 102 connecting to a storage compartment. The humidifying component 100 is located within the storage compartment. A return air vent 302 and the opening 102 are located on opposite sides of the storage compartment. The user retrieves or places items through the opening 102. The return air vent 302 is located away from the user and at the deepest part of the cabinet 101. That is, the return air vent 302 and the humidifying component 100 are located on the same side of the storage compartment; in other words, the humidifying component 100 is located on the side of the shelf 103 closest to the return air vent 302. More specifically, the humidifying component 100 is located in the half-section of the shelf 103 closest to the return air vent 302, that is, the humidifying component 100 is located on the side of the center line of the shelf 103 closest to the return air vent 302.

[0070] Understandably, the first fan 401 has relatively low power and weak driving capability, making it difficult to effectively deliver the high-humidity airflow it generates to the upper area of ​​the storage compartment. The second fan, however, is used to deliver cooling airflow to the storage compartment; it has higher power and stronger driving capability. Therefore, the second fan can be cleverly used to drive the high-humidity airflow generated by the humidification component 100 at high speed, thereby effectively delivering it to the entire space of the storage compartment.

[0071] It should be noted that when the humidification component 100 is in operation, it is mainly in the stage of stopping cooling. Even if the evaporator 301 is located in the air supply duct 201, the evaporator 301 is not in operation. The second fan is kept on to accelerate the high-humidity air blown out by the humidification component 100 and interact with the indoor air of the storage room, reducing the probability of high-humidity airflow frosting due to low temperature.

[0072] Understandably, the refrigeration equipment also includes a first temperature sensor, a second temperature sensor, a humidity sensor, and a controller. The first temperature sensor detects the ambient temperature, the second temperature sensor detects the temperature inside the storage space, and the humidity sensor detects the humidity inside the storage space. The controller is connected to the first temperature sensor, the second temperature sensor, the humidity sensor, the first fan 401, and the ultrasonic generator 406. The controller operates based on signals transmitted from the first temperature sensor, the second temperature sensor, and the humidity sensor. When the first temperature sensor detects that the ambient temperature is high and the refrigeration equipment is set to a low temperature, the temperature inside the storage space is lower than the set temperature, the set humidity is high, and the humidity inside the storage space is lower than the set humidity, the controller controls the first fan 401 and the ultrasonic generator 406 to turn on simultaneously. In other cases, when the humidity inside the storage space is detected to be lower than the set humidity, the controller controls the first fan 401 to turn on and the ultrasonic generator 406 to turn off. When the humidity inside the storage space is detected to be greater than or equal to the set humidity, the controller controls the first fan 401 and the ultrasonic generator 406 to turn off.

[0073] This invention provides a control method for a refrigeration device, applied to a controller disposed within the refrigeration device as described in the above embodiments. The structure or components of the controller have been described in detail in the above embodiments and will not be repeated here. (Refer to...) Figure 6 As shown, the control method of this embodiment includes, but is not limited to, steps S100, S200, S300, S400, and S500.

[0074] Step S100: Obtain the ambient temperature value Th, the storage room temperature setting value Ts, the humidity setting value y, and the humidity measurement value x.

[0075] In one embodiment, the temperature setting value Ts and the humidity setting value y are input by the user.

[0076] In another embodiment, the temperature setting value Ts and the humidity setting value y are retrieved from a program stored in the refrigeration device.

[0077] In one embodiment, the ambient temperature value Th and the humidity measurement value x are obtained by a humidity sensor.

[0078] Step S200: The humidity measurement value x is less than the humidity setting value y.

[0079] When the humidity measurement value x is less than the humidity setting value y, it indicates that the humidity in the storage room is too low and has not met the expected requirements. It is necessary to turn on the humidification mode to increase the humidity in the storage room.

[0080] Step S300: Determine whether the following conditions are met simultaneously: ambient temperature value Th is greater than the first preset value, temperature setting value Ts is less than the second preset value, and humidity setting value y is greater than the third preset value. If yes, proceed to step S300; otherwise, proceed to step S400.

[0081] In one embodiment, the first preset value can be set to 30°C, the second preset value can be set to 8°C, and the third preset value can be set to 75%. When all three conditions are met simultaneously, it indicates that the refrigeration equipment is in a high-temperature environment and requires a low-temperature, high-humidity storage environment. Step S300 is then executed to achieve efficient humidification. If one or more conditions are not met, step S400 is executed, and a general humidification scheme is adopted to reduce the frequency of use of the ultrasonic oscillator and improve its service life.

[0082] In another embodiment, the first preset value can also be set to values ​​such as 28°C, 32°C, and 35°C, the second preset value can be set to values ​​such as 9°C, 6°C, and 5°C, and the third preset value can be set to values ​​such as 70%, 80%, and 85%.

[0083] Step S400: The refrigeration equipment operates in the first working mode: the first fan and ultrasonic generator are turned on.

[0084] It is understandable that when the refrigeration equipment is set to low temperature and high humidity at a high ambient temperature, turning on the first fan and the ultrasonic generator can combine the increased humidity from the two humidification methods, effectively improving humidification efficiency and meeting humidity requirements.

[0085] In step S500, the refrigeration equipment operates in the second working mode, controlling the first fan to turn on and the ultrasonic generator to turn off.

[0086] It is understandable that when the refrigeration equipment is set to low temperature and high humidity in a non-high temperature environment, that is, when the ambient temperature value Th is less than or equal to the first preset value, the temperature setting value Ts is less than the second preset value, and the humidity setting value y is greater than the third preset value, the high humidity air generated by turning on the first fan can meet the humidity requirements.

[0087] It is understandable that when the refrigeration equipment is set to non-low temperature high humidity in a high temperature environment, that is, when the ambient temperature value Th is greater than the first preset value, the temperature setting value Ts is greater than or equal to the second preset value, and the humidity setting value y is greater than the third preset value, the high humidity air generated by turning on the first fan can meet the humidity requirements.

[0088] It is understandable that when the refrigeration equipment is set to low temperature and non-high humidity in a high-temperature environment, that is, when the ambient temperature value Th is greater than the first preset value, the temperature setting value Ts is less than the second preset value, and the humidity setting value y is less than or equal to the third preset value, the high humidity air generated by turning on the first fan can meet the humidity requirements.

[0089] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 7 As shown, Figure 7 yes Figure 6 A schematic diagram of an embodiment of the detailed process of step S400, which includes, but is not limited to, step S410.

[0090] Step S410: Control the second fan to start.

[0091] In this embodiment, when the refrigeration equipment enters the humidification mode, the second fan also turns on. The second fan directs airflow, causing the high-humidity airflow generated by the humidification component to enter the supply air duct from the return air inlet, increasing the flow speed of the high-humidity airflow. This effectively delivers the high-humidity airflow to the entire storage room, improving humidification efficiency and shortening humidification time. By placing the first air outlet of the humidification component near the return air inlet, after the second fan and humidification component are turned on, the high-humidity airflow enters the supply air duct through the return air inlet and finally enters the storage room from the second air outlet. The second fan, used to deliver cooling airflow to the storage room, has high power and strong driving capability. Therefore, it can be cleverly used in humidity control. The second fan's airflow causes the high-humidity airflow generated by the humidification component to flow at high speed, reducing humidity control costs and improving humidification efficiency.

[0092] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 8 As shown, Figure 8 yes Figure 7 A schematic diagram of an embodiment of the detailed process of step S410, which includes, but is not limited to, step S411.

[0093] Step S411: When the refrigeration component is in the on state, the speed of the second fan is Rn1.

[0094] Referring to Table 1, it can be understood that the second fan's speed is divided into four levels: R1, R2, R3, and R4, with the speeds from R1 to R4 corresponding to increasing speeds. The ambient temperature range is divided into eight intervals, with the ambient temperature increasing from interval one to interval eight. It can be understood that when the cooling unit is on, it indicates that the storage room is in a cooling state, and at this time, the second fan's speed Rn1 is specifically either R2 or R3. That is, the second fan's speed is set to meet the cooling demand, and when adjusting humidity, temperature requirements are prioritized.

[0095] Table 1 Speed ​​Control Table for the Second Fan

[0096]

[0097] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 9 As shown, Figure 9 yes Figure 7 A schematic diagram of an embodiment of the detailed process of step S410, which includes, but is not limited to, step S412.

[0098] In step S412, when the cooling component is in the off state, the rotational speed of the second fan is Rn2, where Rn2 > Rn1.

[0099] Understandably, when the cooling unit is off, indicating that the storage compartment is not cooling, the speed Rn2 of the second fan is set to either R3 or R4, and Rn2 > Rn1. That is, when Rn1 is set to R2, Rn2 is specifically either R3 or R4; when Rn1 is set to R3, Rn2 is set to R4. In some embodiments, Rn2 is fixed at R4, meaning that when the cooling unit is off, the speed of the second fan increases to its maximum speed, enabling the humidity to reach the set humidity level most quickly with minimal impact on temperature.

[0100] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 10 As shown, Figure 10 yes Figure 6 A schematic diagram of an embodiment of the detailed process of step S500, which includes, but is not limited to, step S510.

[0101] Step S510: When x < ya, control the first fan and the second fan to start, where a is the first humidity compensation value.

[0102] It's understandable that changing the humidity setting from a single point value 'y' to a range value [ya, y] means that when the humidity measurement value 'x' falls within the range [ya, y], the humidifier and second fan don't need to be turned on, avoiding frequent starts and stops for both. The value of 'a' can be a constant such as 8%, 5%, or 3%. For example, if the humidity setting 'y' is 60% and 'a' is 5%, when the humidity measurement value 'x' is 50%, the humidifier needs to be turned on to supplement the high-humidity airflow, and the cooling equipment enters humidification mode; when the humidity measurement value 'x' is 58%, the humidifier doesn't need to be turned on. However, this also has drawbacks. When the cooling equipment enters humidification mode, the detected humidity measurement value 'x' is already significantly different from the humidity setting 'y'. If only the first fan is turned on, the humidification efficiency is slow, requiring a longer time to reach the humidity setting 'y'. In this embodiment, when the refrigeration equipment enters the humidification mode, the second fan also turns on. The second fan directs airflow, causing the high-humidity airflow generated by the humidification component to enter the supply air duct from the return air inlet, increasing the flow speed of the high-humidity airflow. This effectively delivers the high-humidity airflow to the entire storage room, improving humidification efficiency and shortening humidification time. By placing the first air outlet of the humidification component near the return air inlet, after the second and first fans are turned on, the high-humidity airflow enters the supply air duct through the return air inlet and finally enters the storage room from the second air outlet. The second fan, used to deliver cooling airflow to the storage room, has higher power and stronger driving capability. Therefore, the second fan can be cleverly used in humidity control. The second fan's airflow causes the high-humidity airflow generated by the humidification component to flow at high speed, reducing humidity control costs and improving humidification efficiency.

[0103] The wind speed control logic for the second fan is described in steps S411 and S412.

[0104] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 11 As shown, Figure 11 yes Figure 6 A schematic diagram of an embodiment of the detailed process of step S500, which includes, but is not limited to, step S520.

[0105] Step S520: When x > y + b, control the humidification component to turn off, detect the temperature value Ti of the storage room, and control the working state of the refrigeration component and the second fan according to the working state of the refrigeration component. Here, b is the second humidity compensation value, that is, the value of b is a constant and the unit is humidity unit.

[0106] Understandably, changing the humidity setting from a single-point value 'y' to a range [y, y+b] means that when the humidity measurement value 'x' falls within the range of [y, y+b], the humidifier and second fan do not need to be turned on, avoiding frequent starts and stops of the second fan and humidifier. The value of 'b' can be a constant such as 8%, 5%, or 3%. For example, if the humidity setting 'y' is 80% and 'a' is 5%, when the humidity measurement value 'x' is 88%, the humidifier needs to be turned off, and the cooling unit and second fan need to be turned on, putting the cooling equipment into dehumidification mode. When the humidity measurement value 'x' is 82%, the cooling unit and second fan do not need to be turned on. In cooling mode, the air is cooled by the evaporator, causing water vapor in the air to condense into water droplets, thus achieving the dual effects of cooling and dehumidification. Specifically, when the cooling equipment is set to cooling mode, the air in the storage room is drawn in and cooled by the evaporator. During this process, water vapor in the air condenses upon cooling, turning into liquid water, thereby dehumidifying the air in the storage room.

[0107] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 12 As shown, Figure 12 yes Figure 11 A schematic diagram of an embodiment of the detailed process of step S520, which includes, but is not limited to, step S521.

[0108] Step S521: When the temperature value Ti of the storage room is less than or equal to the preset temperature value Ts, and the refrigeration component is in the on state, control the refrigeration component and the second fan to shut down.

[0109] Understandably, when x > y + b, it indicates that the measured humidity value x is greater than the required humidity setting value y, which normally necessitates dehumidification, and the cooling unit is also on, enabling dehumidification. However, if the temperature sensor detects that the storage compartment temperature value Ti is less than or equal to the preset temperature value Ts, activating the cooling unit would cause the storage compartment temperature to continue to decrease, affecting temperature control. Therefore, the cooling unit and the second fan are shut down here, prioritizing temperature requirements when humidity and temperature control conflict.

[0110] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 13 As shown, Figure 13 yes Figure 10 A schematic diagram of an embodiment of the detailed process of step S520, which includes, but is not limited to, step S522.

[0111] Step S322: When the temperature Ti of the storage room is greater than the preset temperature Ts and the refrigeration component is in the on state, the refrigeration component and the second fan remain in the on state.

[0112] It is understandable that when x > y + b, it means that the humidity measurement value x is greater than the required humidity setting value y. Normally, dehumidification is required, and the refrigeration component is also in the on state. Continue to keep the refrigeration component and the second fan in the on state to meet the requirements of both cooling and dehumidification. At this time, the speed of the second fan is controlled according to the temperature control logic when the storage room is in the cooling state.

[0113] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 14 As shown, Figure 14 yes Figure 11 A schematic diagram of an embodiment of the detailed process of step S520, which includes, but is not limited to, step S523.

[0114] Step S323: When the temperature value Ti of the storage room is less than or equal to the preset temperature value Ts, and the refrigeration component is in the off state, control the refrigeration component and the second fan to remain in the off state.

[0115] Understandably, when x > y + b, it indicates that the measured humidity value x is greater than the required humidity setting value y, and dehumidification is normally required. However, the temperature sensor detects that the temperature value Ti of the storage compartment is less than or equal to the preset temperature value Ts. Activating the cooling system would cause the temperature of the storage compartment to continue to decrease, affecting temperature control, and the cooling system is currently in a turned-off state. Therefore, the cooling system and the second fan are kept off, prioritizing temperature requirements when humidity control and temperature control conflict.

[0116] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 15 As shown, Figure 15 yes Figure 11 A schematic diagram of an embodiment of the detailed process of step S520, which includes, but is not limited to, step S524.

[0117] Step S524: When the temperature Ti of the storage room is greater than the preset temperature Ts and the refrigeration unit is in the off state, control the refrigeration unit and the second fan to turn on.

[0118] It is understandable that when x > y + b, it means that the humidity measurement value x is greater than the required humidity setting value y, and dehumidification is normally required. Also, the temperature value Ti of the storage room is detected to be greater than the preset temperature value Ts, so cooling is required to lower the temperature. The cooling components and the second fan are turned on to meet the requirements of cooling and dehumidification at the same time. At this time, the speed of the second fan is controlled according to the temperature control logic when the storage room is in the cooling state.

[0119] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 16 As shown, Figure 16 yes Figure 6 A schematic diagram of an embodiment of the detailed process of step S500, which includes, but is not limited to, step S530.

[0120] Step S530: When ya≤x≤y+b, control the humidification component to turn off.

[0121] Understandably, changing the humidity setting from a single-point value y to a range [ya, y+b] means that when the humidity measurement value x falls within the range [ya, y+b], the compressor and second fan do not need to be turned on, thus avoiding frequent starts and stops. The value of 'a' can be a constant such as 8%, 5%, or 3%, and the value of 'b' can also be a constant such as 8%, 5%, or 3%. For example, if the humidity setting y is 60%, 'a' is 5%, and 'b' is 5%, when the humidity measurement value x is 50%, the humidifier needs to be turned on to supplement the high-humidity airflow, and the cooling equipment enters humidification mode. When the humidity measurement value x is 58%, the humidifier does not need to be turned on. When the humidity measurement value x is 80%, the humidifier needs to be turned off, and the cooling component should be turned on for dehumidification based on the detected temperature value. When ya ≤ x ≤ y+b, if the storage room is in cooling mode, the second fan speed is R2 or R3; if the storage room is not in cooling mode, the second fan speed is R1 or R2. When the humidity is sufficient, turning on the second fan is to improve the temperature and humidity uniformity within the refrigeration equipment. The fan keeps rotating to ensure that the upper and lower parts of the storage room have uniform temperature and humidity.

[0122] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 17 As shown, Figure 17 This is a complete embodiment of a humidification method using a single first fan in the control method of a refrigeration equipment, which will be described below with specific steps.

[0123] The system acquires the humidity setpoint 'y' and the measured humidity value 'x', determines the humidity level, confirms the humidity range, and controls the operating mode of the refrigeration equipment accordingly. When x < y - 5, it indicates that the humidity in the storage space is too low, and the refrigeration equipment is switched to humidification mode. When x > y + 5, it indicates that the humidity in the storage space is too high, and the refrigeration equipment is switched to dehumidification mode. When y - 5 ≤ x ≤ y + 5, it indicates that the humidity in the storage space meets the requirements, and humidity control is not necessary. The following details the specific control process for each humidity range in conjunction with temperature conditions.

[0124] When x < y - 5, determine whether the refrigeration equipment is in the refrigeration stage. If the refrigeration equipment is in the refrigeration stage, the second fan operates at the same speed as the fan with the same temperature control specifications under the same conditions. That is, the opening and closing of the second fan, as well as the speed control, are adjusted according to the needs of temperature control. Refer to Table 1 for the speed control table of the storage room in the refrigeration state, and the first fan is turned on. If the refrigeration equipment is not in the refrigeration stage, the second fan operates at the R4 speed setting, that is, the speed of the second fan increases to the maximum speed, and the first fan is turned on until the humidity reaches the set humidity.

[0125] When x > y + 5, determine if the refrigeration equipment is in the cooling stage. If it is, the second fan operates at the same speed as the fan with the same temperature control specifications under the same conditions. That is, the opening and closing of the second fan, as well as its speed control, are adjusted according to the temperature control requirements. Refer to Table 1 for the speed control table of the storage room in cooling mode. The humidification component is also turned on. The system continuously checks if the temperature has reached the stop point, i.e., whether the detected temperature value has reached the preset temperature value. If the stop point is reached, the evaporator stops cooling, i.e., the compressor is turned off, the second fan is not turned on, and the humidification component is not turned on. If the stop point is not reached, the evaporator continues cooling, continuing the previous fan speed control strategy. If the refrigeration equipment is not in the cooling stage, it is also necessary to determine if the temperature has reached the stop point. If the stop point is not reached, the evaporator starts cooling, and the second fan operates at the same speed as the fan with the same temperature control specifications under the same conditions. If the stop point is reached, the evaporator stops cooling, i.e., the compressor is turned off, the second fan is not turned on, and the humidification component is not turned on.

[0126] When y-5≤x≤y+5, the second fan has the same speed as the fan with the same temperature control specification under the same conditions. You can refer to Table 1 for the speed control table when the storage room is in a non-cooling state (only executed when the humidity meets the requirements), and the humidification component is not turned on.

[0127] In all three humidity control strategies mentioned above, it is necessary to read the new measured value x in real time and then return to the step of determining the humidity.

[0128] This invention also provides a control device for a refrigeration device. The control device is built into the refrigeration device and includes one or more control processors and a memory, taking one control processor and one memory as an example.

[0129] The control processor and memory can be connected via a bus or other means, taking a bus connection as an example.

Furthermore, memory may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device.
