Description

Technical Field

[0001] This invention relates to the field of refrigeration control technology, and in particular to control methods and devices for refrigeration equipment, and refrigeration equipment. Background Technology

[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 degrading its quality. Too high humidity will cause the cork to mold, further ruining the wine. In related technologies, the power of the humidification components is limited by the space available in the mounting bracket, resulting in low humidification efficiency during the humidification process. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a control method for refrigeration equipment that can improve humidification efficiency.

[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] Figure 1 and Figure 2 The image shown is a refrigeration device according to an embodiment of the present invention. The refrigeration device can specifically be a refrigerator, wine cooler, or other similar products. Figure 3 for Figure 2 The enlarged view at point C is shown. (Refer to...) Figures 1 to 3 As shown, the refrigeration equipment of the relevant technology includes a cabinet 101, a refrigeration component, and a humidification component 100. The cabinet 101 has a storage compartment and an air supply duct 201 for delivering airflow to the storage compartment. The refrigeration component provides a cooling environment for the storage compartment and includes an evaporator 301 and a compressor, configured to controllably generate a cooling airflow and direct it through the air supply duct 201 to the storage compartment. In other words, the refrigeration component is used to cool the storage compartment. The humidification component 100 is located in the cabinet 101 and configured to controllably generate a high-humidity airflow and deliver it to the storage compartment. It is understood that the high-humidity airflow contains a high level of moisture, which increases the humidity within the storage compartment.

[0060] Reference Figure 2 and Figure 3 As 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 humidification component 100 is provided with a first air outlet 104. The high-humidity airflow generated by the humidification component 100 flows out from the first air outlet 104. The first air outlet 104 is positioned close to the return air outlet 302, so that 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.

[0061] For example, refer to Figure 1As 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.

[0062] Understandably, humidification components 100 generally fall into two categories: passive and active. Passive humidification components include simple water collection boxes or humidifying materials 406 such as volcanic rock or non-woven fabric added to the water box. They increase the humidity inside the refrigeration equipment by relying on the natural evaporation of water. However, passive humidification is not convenient for controlling the humidity inside the refrigeration equipment, and the humidity fluctuates greatly. Active humidification components include a first fan 401, which blows air to expel moisture into the internal space of the refrigeration equipment.

[0063] It should be noted that, in this embodiment, when the humidification component 100 is a passive structure, the mention of turning the humidification component 100 on or off refers to turning the first air outlet 104 on or off via a switch structure. When the humidification component 100 is an active structure, the mention of turning the humidification component 100 on or off refers to turning the first fan 401 on or off.

[0064] Reference Figure 4 and Figure 5 As shown, the following description uses the humidification component 100 as an active structure.

[0065] Reference Figure 4As shown, it can be understood that a humidification assembly 100 in one embodiment includes a housing 402, a first fan 401, and a humidifying material 406. 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 and allowing communication between their tops. The first fan 401 is disposed in the first mounting groove 403, and the humidifying material 406 is disposed in the second mounting groove 404. The humidifying material 406 can be made of materials such as volcanic rock or non-woven fabric. In other words, the humidifying material 406 can be a porous, multi-layered absorbent material. The diameter and volume of the pores in the porous, multi-layered absorbent material are smaller than the diameter and volume of a normally falling water droplet, so that water droplets cannot flow through the porous, multi-layered absorbent material while allowing airflow. After the first fan 401 is started, dry air passes over the surface of the humidifying material 406. The air with high humidity on the surface of the humidifying material 406 enters the storage compartment and mixes with the air, thereby increasing the relative humidity of the storage compartment. After the humid air above the humidifying material 406 is carried away, it can quickly absorb moisture from the bottom of the humidifying material 406 and evaporate it to the top (water vapor density is low), thus maintaining a high humidity state above the humidifying material 406.

[0066] The humidification assembly 100 also includes a cover plate 408, which is connected to the housing 402 and located above the first mounting groove 403 and the second mounting groove 404. There is a gap between the cover plate 408 and the humidifying material 406 to form a humidification channel. The cover plate 408 is provided with a plurality of spaced-apart first air outlets 104, from which highly humidified air flows out respectively.

[0067] Reference Figure 4 As shown, the humidifying assembly 100 includes a connecting duct 407. In this embodiment, the connecting duct 407 is used to guide the airflow blown by the first fan 401 to the outer surface of the humidifying material 406. The connecting duct 407 has a first port and a second port. The first port is connected to the outlet of the first fan 401, and the second port faces the gap between the cover plate 408 and the humidifying material 406. The first fan 401, the connecting duct 407, and the humidifying material 406 are arranged along the length of the housing 402.

[0068] Reference Figure 5As shown, it can be understood that the humidification component 100 in another embodiment includes a housing 402, a first fan 401, and a distribution duct 501. The housing 402 has a first mounting groove 403 and a second mounting groove 404. The first fan 401 is disposed in the first mounting groove 403, and water or humidifying material 406 is placed in the second mounting groove 404 to form a water storage component. The distribution duct 501 passes through the first mounting groove 403 and the second mounting groove 404. The distribution duct 501 is connected to the first fan 401 and has multiple third air outlets 502. All third air outlets 502 face the water storage component, meaning that the airflow generated by the first fan 401 is divided into multiple branch airflows through all the third air outlets 502 before passing through the water storage component.

[0069] Reference Figure 5 As shown, it can be understood that multiple equally spaced partitions 503 are also provided inside the housing 402. The multiple partitions 503 are arranged along the length of the air distribution duct 501, that is, along the direction away from the first fan 401. One or more third air outlets 502 are provided between every two partitions 503, so that each pair of partitions 503 forms an independent humidification unit. The function of the partitions 503 is to prevent the various humidification units from affecting or interfering with each other, thereby ensuring the uniformity of humidification of the humidification component 100 at all positions.

[0070] Reference Figure 5 As shown, the humidification assembly 100 includes a connecting duct 407. In this embodiment, the connecting duct 407 is used to guide the airflow blown by the first fan 401 to the distribution duct 501. The connecting duct 407 has a first port and a second port. The first port is connected to the outlet of the first fan 401, and the second port is connected to the distribution duct 501. The first fan 401, the connecting duct 407, and the distribution duct 501 are arranged along the length of the housing 402. The distribution duct 501 is located on one side of the housing 402 in the width direction and above the water storage component. By providing the connecting duct 407, the airflow generated by the first fan 401 can be more concentrated through the distribution duct 501, thereby improving the humidification efficiency.

[0071] It should be noted that the water storage component can also be replaced by a humidifier, such as an ultrasonic humidifier or a steam (thermal evaporation) humidifier. In another embodiment, the humidification assembly 100 includes a first fan 401 and a humidifier. Ultrasonic humidifiers atomize water into micron-sized particles using a high-frequency vibrating ultrasonic transducer (typically a ceramic or metal element), which is then dispersed into the air by a fan. This technology does not generate heat and is therefore called a "cold mist" humidifier. Steam humidifiers heat water to boiling using a heating element, producing steam, which is then released into the air. This type of humidifier is also called a "hot mist" humidifier.

[0072] 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.

[0073] 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.

[0074] It is understood that the refrigeration equipment in this embodiment of the invention also includes a control device, a temperature sensor, and a humidity sensor. The control device is connected to the temperature sensor, the humidity sensor, the second fan, the refrigeration component, and the humidification component 100, respectively. The temperature sensor can be used to acquire the temperature value inside the storage room, the humidity sensor can be used to acquire the humidity measurement value x inside the storage room, and the control device can be used to determine the operating mode of the refrigeration equipment based on the temperature signal output by the temperature sensor and the humidity signal output by the humidity sensor.

[0075] It should be noted that the working modes of the refrigeration equipment include humidification mode and dehumidification mode, etc. This embodiment does not impose specific limitations on them. In this embodiment, all control logic prioritizes meeting the temperature requirements before adjusting the humidity.

[0076] This invention provides a control method for a refrigeration device, applied to a control device disposed within the refrigeration device as described in the above embodiments. The structure or components of the control device 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, and S300.

[0077] Step S100: Obtain the humidity setpoint y.

[0078] In one embodiment, the humidity setting value y is input by the user.

[0079] In another embodiment, the humidity setpoint y is invoked from a program stored within the refrigeration device.

[0080] Step S200: Obtain the humidity measurement value x.

[0081] In one embodiment, the humidity measurement value x is obtained by a humidity sensor.

[0082] Step S300: Control the operating mode of the refrigeration equipment according to the humidity setpoint y and the humidity measurement value x.

[0083] Understandably, 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 reached the expected level. In this case, the humidifier mode should generally be turned on to increase the humidity. When the humidity measurement value x equals the humidity setting value y, it indicates that the humidity in the storage room has just reached the expected level, and the humidifier does not need to be turned on. When the humidity measurement value x is greater than the humidity setting value y, it indicates that the humidity in the storage room is too high. In this case, in addition to turning off the humidifier, dehumidification may also be necessary.

[0084] 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 S300, which includes, but is not limited to, step S310.

[0085] Step S310: When x < ya, control the humidification component and the second fan to turn on, where a is the first humidity compensation value, that is, the value of a is a constant and the unit is humidity unit.

[0086] Understandably, 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 do not need to be turned on, thus avoiding frequent starts and stops of the second fan and humidifier. 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 does not 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 humidifier is turned on, the humidification efficiency is slow, and it takes a long 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 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 a large power and strong 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.

[0087] 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 S310, which includes, but is not limited to, step S311.

[0088] Step S311: When the refrigeration component is in the on state, the speed of the second fan is Rn1.

[0089] 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 increasing from R1 to R4. This means that when the cooling unit is on, the storage compartment is in cooling mode, and the second fan's speed Rn1 is either R2 or R3. In other words, the second fan's speed is set to meet cooling requirements, prioritizing temperature control when adjusting humidity.

[0090] 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 7A schematic diagram of an embodiment of the detailed process of step S310, which includes, but is not limited to, step S312.

[0091] In step S312, when the refrigeration component is in the off state, the rotational speed of the second fan is Rn2, where Rn2 > Rn1.

[0092] 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.

[0093] Table 1 Speed ​​Control Table for the Second Fan

[0094]

[0095] 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 S300, which includes, but is not limited to, step S320.

[0096] Step S320: When x > y + b, control the humidification component to turn off, detect the temperature value 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.

[0097] 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.

[0098] 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 10 A schematic diagram of an embodiment of the detailed process of step S320, which includes, but is not limited to, step S321.

[0099] Step S321: When the temperature value of the storage room is less than or equal to the preset temperature value and the refrigeration component is in the on state, control the refrigeration component and the second fan to shut down.

[0100] 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 to perform dehumidification. However, if the temperature sensor detects that the temperature in the storage compartment is less than or equal to the preset temperature value, activating the cooling unit would cause the temperature in the storage compartment to continue to decrease, affecting temperature control. Therefore, the cooling unit and the second fan are shut down here, prioritizing temperature requirements when humidity control and temperature control conflict.

[0101] 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 10 A schematic diagram of an embodiment of the detailed process of step S320, which includes, but is not limited to, step S322.

[0102] Step S322: When the temperature of the storage room is greater than the preset temperature value and the refrigeration component is in the on state, the refrigeration component and the second fan remain in the on state.

[0103] 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.

[0104] 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 S320, which includes, but is not limited to, step S323.

[0105] Step S323: When the temperature value of the storage room is less than or equal to the preset temperature value and the refrigeration component is in the off state, control the refrigeration component and the second fan to remain in the off state.

[0106] 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 in the storage room is less than or equal to the preset temperature value. Activating the cooling system would cause the temperature in the storage room to continue to drop, affecting temperature control, and the cooling system is currently off. Therefore, the cooling system and the second fan are kept off, prioritizing temperature control when there is a conflict between humidity and temperature control.

[0107] 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 10 A schematic diagram of an embodiment of the detailed process of step S320, which includes, but is not limited to, step S324.

[0108] Step S324: When the temperature of the storage room is greater than the preset temperature value and the refrigeration unit is in the off state, control the refrigeration unit and the second fan to turn on.

[0109] 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 of the storage room is detected to be greater than the preset temperature value, 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.

[0110] 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 6 A schematic diagram of an embodiment of the detailed process of step S300, which includes, but is not limited to, step S330.

[0111] Step S330: When ya≤x≤y+b, control the humidification component to turn off.

[0112] 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.

[0113] Another embodiment of the present invention also provides a control method for a refrigeration device, such as... Figure 16 As shown, Figure 16 This is a complete embodiment of a control method for refrigeration equipment, which will be explained below with specific steps.

[0114] 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.

[0115] 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 humidification component is turned on. If the refrigeration equipment is not in the refrigeration stage, the second fan operates at the R4 speed, that is, the speed of the second fan increases to the maximum speed, and the humidification component is turned on until the humidity reaches the set humidity.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.
