The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Figure 1 and Figure 2 The refrigeration device of the embodiment of the present invention is shown. The refrigeration device may be a refrigerator, a wine cabinet, etc. Figure 3 for Figure 2 The enlarged view of point C is shown. Figures 1 to 3As shown, it can be understood that the refrigeration equipment of the related art includes a cabinet 101, a refrigeration assembly and a humidification assembly 100, the cabinet 101 is provided with a storage room and an air supply duct 201 for conveying airflow to the storage room, the refrigeration assembly is used to provide a refrigeration environment for the storage room, and the refrigeration assembly includes an evaporator 301 and a compressor, which is configured to generate a cooling airflow in a controlled manner and cause the cooling airflow to be sent to the storage room through the air supply duct 201. In other words, the refrigeration assembly is used to cool the storage room. The humidification assembly 100 is arranged in the cabinet 101, configured to generate a high-humidity airflow in a controlled manner, and convey the high-humidity airflow to the storage room. It can be understood that the moisture in the high-humidity airflow is large, which can increase the humidity in the storage room.

[0027] Reference Figure 2 and Figure 3 As shown, it can be understood that the air supply duct 201 includes a second air outlet 202 and a return air outlet 302 connected to the storage compartment, the second air outlet 202 is located at the top of the storage compartment, and the return air outlet 302 is located at the bottom of the storage compartment. The refrigeration device includes a second fan for promoting air circulation between the storage compartment and the air supply duct 201. The humidification component 100 is provided with a first air outlet 104, and the high humidity airflow generated by the humidification component 100 flows out from the first air outlet 104. The first air outlet 104 is arranged at a position close to the position close to the return air outlet 302, so that when the second fan and the humidification component 100 are both in working state, 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 compartment through the second air outlet 202. After secondary acceleration by the second fan, the high-humidity airflow comes out from the second air outlet 202 and mixes more fully with the air in the storage room, thereby further improving the humidification efficiency.

[0028] For example, refer to Figure 1 As shown, the cabinet 101 includes a shelf 103, and the humidifying assembly 100 is arranged on the shelf 103. The cabinet 101 is provided with an opening 102, and the opening 102 is connected to the storage room. The humidifying assembly 100 is located in the storage room, and the return air port 302 and the opening 102 are located on opposite sides of the storage room. The user takes and puts items from the opening 102, and the return air port 302 is far away from the user. The return air port 302 is located at the deepest part of the cabinet 101. That is, the return air port 302 and the humidifying assembly 100 are located on the same side of the storage room. In other words, the humidifying assembly 100 is located on the side of the shelf 103 close to the return air port 302. More specifically, the humidifying assembly 100 is located in the half area of ​​the shelf 103 close to the return air port 302, that is, the humidifying assembly 100 is located on the side of the midline of the shelf 103 close to the return air port 302.

[0029] It is understandable that the types of humidification components 100 are generally divided into two types. One is a passive type, including a simple water receiving box or adding humidification materials 406 such as volcanic rocks and non-woven fabrics to the water box, using the passive method of natural evaporation of water to increase the humidity in the refrigeration device. The passive humidification method is not convenient for controlling the humidity in the refrigeration device, and the humidity in the refrigeration device fluctuates greatly. The other is an active type, including a first fan 401, using the wind blown by the first fan 401 to drive the moisture to the internal space of the refrigeration device.

[0030] It should be noted that, in this embodiment, when the humidifying component 100 is a passive structure, the reference to opening or closing the humidifying component 100 refers to opening or closing the first air outlet 104 through the switch structure. When the humidifying component 100 is an active structure, the reference to opening or closing the humidifying component 100 refers to opening or closing the first fan 401.

[0031] Reference Figure 4 and Figure 5 As shown, the humidifying component 100 is described below as an active structure.

[0032] Reference Figure 4 As shown, it can be understood that a humidification component 100 of an embodiment includes a housing 402, a first fan 401 and a humidification material 406, a first mounting groove 403 and a second mounting groove 404 are provided in the housing 402, a partition bar 405 is provided between the first mounting groove 403 and the second mounting groove 404, and the partition bar 405 is located at the bottom of the first mounting groove 403 and the second mounting groove 404, so that the bottom of the first mounting groove 403 and the second mounting groove 404 cannot be connected, while the top of the first mounting groove 403 and the second mounting groove 404 can be connected. The first fan 401 is arranged in the first mounting groove 403, and the humidification material 406 is arranged in the second mounting groove 404. The humidifying material 406 can be a material such as volcanic rock or non-woven fabric, that is, the humidifying material 406 can be a porous dense structure water-absorbing material, and the diameter and volume of the holes on the porous dense structure water-absorbing material are smaller than the diameter and volume of the normally dripping water droplets, so that the water droplets cannot flow through the porous dense structure water-absorbing material, while allowing air flow to pass through. After the first fan 401 is started, dry air passes through the surface of the humidifying material 406, and the air with high humidity on the surface of the humidifying material 406 reaches the storage room and mixes with the air, thereby increasing the relative humidity of the storage room. After the humid air above the humidifying material 406 is taken away, it can quickly absorb the moisture at the bottom of the humidifying material 406 and evaporate to the top (the water vapor density is small), so that the air above the humidifying material 406 remains in a high humidity state.

[0033] The humidification assembly 100 further includes a cover plate 408, which is connected to the housing 402 and is located above the first mounting groove 403 and the second mounting groove 404. There is a gap between the cover plate 408 and the humidification material 406 to form a humidification channel. The cover plate 408 is provided with a plurality of first air outlets 104 arranged at intervals, and high-humidity air flows out from the plurality of first air outlets 104 respectively.

[0034] Reference Figure 4 As shown, it can be understood that the humidification component 100 includes a connecting air duct 407. In this embodiment, the connecting air duct 407 is used to guide the airflow blown out by the first fan 401 to the outer surface of the humidification material 406. The connecting air duct 407 is provided with a first pipe opening and a second pipe opening, the first pipe opening is connected to the outlet of the first fan 401, and the second pipe opening is toward the gap between the cover plate 408 and the humidification material 406. The first fan 401, the connecting air duct 407 and the humidification material 406 are arranged along the length direction of the housing 402.

[0035] Reference Figure 5 As shown, it can be understood that the humidification component 100 of another embodiment includes a housing 402, a first fan 401 and an air distribution duct 501, a first mounting groove 403 and a second mounting groove 404 are provided in the housing 402, the first fan 401 is provided in the first mounting groove 403, water or a humidifying material 406 is placed in the second mounting groove 404 to form a water storage member, and the air distribution duct 501 runs through the first mounting groove 403 and the second mounting groove 404. The air distribution duct 501 is connected to the first fan 401, and the air distribution duct 501 is provided with a plurality of third air outlets 502, all of which face the water storage member, that is, the conveying airflow generated by the first fan 401 is divided into a plurality of branch airflows through all the third air outlets 502 and then passes through the water storage member.

[0036] Reference Figure 5 As shown, it can be understood that a plurality of equally spaced partitions 503 are further provided in the housing 402, and the plurality of partitions 503 are arranged along the length direction of the air distribution duct 501, that is, arranged in a direction away from the first fan 401. One or more third air outlets 502 are provided between every two partitions 503, so that an independent humidification unit is formed between every two partitions 503, and the function of the partition 503 is to prevent the various humidification units from being easily affected or interfered with, thereby ensuring the humidification uniformity of the humidification assembly 100 at various positions.

[0037] Reference Figure 5As shown, it can be understood that the humidification component 100 includes a connecting air duct 407. In this embodiment, the connecting air duct 407 is used to guide the airflow blown out by the first fan 401 to the air distribution duct 501. The connecting air duct 407 is provided with a first pipe opening and a second pipe opening, the first pipe opening is connected to the outlet of the first fan 401, and the second pipe opening is connected to the air distribution duct 501. The first fan 401, the connecting air duct 407 and the air distribution duct 501 are arranged along the length direction of the shell 402, and the air distribution duct 501 is arranged on one side of the width direction of the shell 402 and is located above the water storage part. By providing the connecting air duct 407, the airflow generated by the first fan 401 can pass through the air distribution duct 501 more concentratedly, thereby improving the humidification efficiency.

[0038] It should be noted that the water storage member can also be replaced by a humidifier, for example, the type of humidifier is an ultrasonic humidifier or a steam (thermal evaporation) humidifier, that is, the humidification component 100 of another embodiment includes a first fan 401 and a humidifier. Among them, the ultrasonic humidifier uses a high-frequency vibrating ultrasonic transducer (usually a ceramic or metal element) to atomize water into micron-sized particles, and then blows the water mist into the air through a fan. This technology does not generate heat, so it is called a "cold mist" humidifier. A steam humidifier heats water to boiling through a heating element to generate steam, and then releases the steam into the air. This type of humidifier is also called a "hot mist" humidifier.

[0039] It is understandable that the first fan 401 has a relatively small power and a relatively weak driving capability, and it is difficult to effectively deliver the high-humidity airflow generated by it to the upper area of ​​the storage compartment. The second fan is used to deliver cooling airflow to the storage compartment, and it has a relatively large power and a relatively strong driving capability. Therefore, the second fan can be cleverly used to deliver air to cause the high-humidity airflow generated by the humidification assembly 100 to flow at a high speed, thereby effectively delivering it to the entire space of the storage compartment.

[0040] It should be noted that when the humidifying component 100 is in working state, mainly in the stage of stopping cooling, even if the evaporator 301 is located in the air supply duct 201, the evaporator 301 is in a non-working state, and the second fan is kept turned on to accelerate the high-humidity air blown out by the humidifying component 100 and interact with the indoor air of the storage room, thereby reducing the probability of frost of the high-humidity airflow due to low temperature.

[0041] It can be understood that the refrigeration device of the embodiment of the present invention further includes a control device, a temperature sensor and a humidity sensor, and the control device is respectively connected to the temperature sensor, the humidity sensor, the second fan, the refrigeration component and the humidification component 100. Among them, the temperature sensor can be used to obtain the temperature value of the storage room, the humidity sensor can be used to obtain the humidity measurement value x in the storage room, and the control device can be used to control the working mode of the refrigeration device according to the temperature signal output by the temperature sensor and the humidity signal output by the humidity sensor.

[0042] It should be noted that the working modes of the refrigeration equipment include a humidification mode and a dehumidification mode, etc., which are not specifically limited in this embodiment. All control logics in this embodiment give priority to satisfying the temperature requirement and then adjusting the humidity.

[0043] The embodiment of the present invention provides a control method for refrigeration equipment, which is applied to the control device provided in the refrigeration equipment in the above embodiment, wherein the structure or component composition of the control device has been described in detail in the above embodiment and will not be repeated here. Figure 6 As shown, the control method of the embodiment of the present invention includes but is not limited to step S100, step S200, and step S300.

[0044] Step S100, obtaining a humidity setting value y.

[0045] In one embodiment, the humidity setting value y is input by the user.

[0046] In another embodiment, the humidity setting value y is called from a program stored in the refrigeration device.

[0047] Step S200, obtaining a humidity measurement value x.

[0048] In one embodiment, the humidity measurement value x is detected by a humidity sensor.

[0049] Step S300, controlling the working mode of the refrigeration equipment according to the humidity setting value y and the humidity measurement value x.

[0050] It is understandable that when the humidity measurement value x is less than the humidity setting value y, it indicates that the humidity in the storage room is low and does not meet the expected requirements. Generally, it is necessary to turn on the humidification mode to humidify the storage room to increase the humidity. When the humidity measurement value x is equal to the humidity setting value y, it indicates that the humidity in the storage room just meets the expected requirements, and the humidification component 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 high. Generally, in addition to turning off the humidification component, dehumidification may also be required.

[0051] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Figure 7 As shown, Figure 7yes Figure 6 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S300 in FIG. 4 , wherein step S300 includes but is not limited to step S310.

[0052] Step S310, when x<ya, control the humidification component and the second fan to turn on, wherein a is the first humidity compensation value, that is, the value of a is a constant, and the unit is the humidity unit.

[0053] It is understandable that when the set humidity is changed from a single point value y to a range value [ya,y], that is, when the humidity measurement value x falls within the range [ya,y], there is no need to turn on the humidification component and the second fan, which can avoid frequent startup of the second fan and the humidification component. The value of a can be a constant such as 8%, 5%, 3%. If the humidity setting value y is 60% and a is 5%, when the humidity measurement value x is 50%, the humidification component needs to be turned on to supplement the high-humidity airflow, and the refrigeration equipment enters the humidification mode; when the humidity measurement value x is 58%, the humidification component does not need to be turned on. However, this also has disadvantages, that is, when the refrigeration equipment enters the humidification mode, the detected humidity measurement value x is already much different from the humidity setting value y. If only the humidification component is turned on, the humidification efficiency is slow and it takes a long time to reach the humidity setting value y. In this embodiment, when the refrigeration device enters the humidification mode, the second fan also enters the on state, and the second fan is used to supply air to cause the high-humidity airflow generated by the humidification component to enter the air supply duct from the return air port, thereby increasing the flow rate of the high-humidity airflow, thereby effectively delivering the high-humidity airflow to the entire space of the storage compartment, improving the humidification efficiency, and shortening the humidification time. By arranging the first air outlet of the humidification component close to the return air port, after turning on the second fan and the humidification component, the high-humidity airflow enters the air supply duct through the return air port, and finally enters the storage compartment from the second air outlet. The second fan is used to deliver cooling airflow to the storage compartment, and its power is relatively large and its driving ability is relatively strong. Therefore, the second fan can be cleverly used to participate in humidity control. The second fan supplies air to cause the high-humidity airflow generated by the humidification component to flow at a high speed, thereby reducing the humidity control cost and improving the humidification efficiency.

[0054] 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 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S310 in FIG. 4 , wherein step S310 includes but is not limited to step S311.

[0055] Step S311, when the refrigeration component is in the on state, the speed of the second fan is Rn1.

[0056] Referring to Table 1, it can be understood that the speed of the second fan is divided into four gears: R1, R2, R3 and R4, and the speeds from R1 to R4 are arranged from small to large. It can be understood that when the refrigeration component is in the on state, it indicates that the storage room is in the refrigeration state. At this time, the speed Rn1 of the second fan is specifically R2 or R3. That is, the speed of the second fan is set to meet the refrigeration demand, and the temperature requirement is preferentially met when the humidity is adjusted.

[0057] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig. 9 As shown, Fig. 9 yes Figure 7 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S310 in FIG. 4 , wherein step S310 includes but is not limited to step S312.

[0058] Step S312, when the refrigeration component is in the closed state, the rotation speed of the second fan is Rn2, wherein Rn2>Rn1.

[0059] It is understandable that when the refrigeration component is in the off state, indicating that the storage room is in a non-refrigeration state, the speed Rn2 of the second fan is set to R3 or R4, and Rn2>Rn1 is satisfied. That is, when Rn1 is set to R2, Rn2 is specifically R3 or R4; when Rn1 is set to R3, Rn2 is set to R4. In some embodiments, Rn2 is fixedly set to R4, that is, when the refrigeration component is in the off state, the speed of the second fan is increased to the maximum speed, which can make the humidity reach the set humidity as quickly as possible, with little impact on the temperature.

[0060] Table 1 Speed ​​control table of the second fan

[0061] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.10 As shown, Fig.10 yes Figure 6 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S300 in FIG. 4 , wherein step S300 includes but is not limited to step S320.

[0062] Step S320, when x>y+b, control the humidification component to be turned off, detect the temperature value of the storage compartment and control the working state of the refrigeration component and the second fan according to the working state of the refrigeration component, wherein b is the second humidity compensation value, that is, the value of b is a constant, and the unit is the humidity unit.

[0063] It is understandable that when the set humidity is changed from the single point value y to the range value [y,y+b], that is, when the humidity measurement value x falls within the range [y,y+b], the humidification component and the second fan do not need to be turned on, which can avoid frequent startup of the second fan and the humidification component. The value of b can be a constant such as 8%, 5%, 3%. If the humidity setting value y is 80% and a is 5%, when the humidity measurement value x is 88%, the humidification component needs to be turned off, and the refrigeration component and the second fan need to be turned on, and the refrigeration equipment enters the dehumidification mode; when the humidity measurement value x is 82%, the refrigeration component and the second fan do not need to be turned on. In the refrigeration mode, the air is cooled by the evaporator, so that the water vapor in the air condenses into water droplets, thereby achieving the dual effects of cooling and dehumidification. Specifically, when the refrigeration equipment is set to the refrigeration mode, the air in the storage room is sucked in and cooled by the evaporator. In this process, the water vapor in the air condenses due to the cold and is converted into liquid water, thereby achieving the dehumidification of the air in the storage room.

[0064] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.11 As shown, Fig.11 yes Fig.10 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S320 in FIG. 4 , wherein step S320 includes but is not limited to step S321.

[0065] Step S321, when the temperature value of the storage compartment is less than or equal to the preset temperature value, and the refrigeration component is in the on state, the refrigeration component and the second fan are controlled to be turned off.

[0066] It can be understood 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, and the refrigeration component is also in the on state, and dehumidification can be performed. However, the temperature sensor detects that the temperature value of the storage room is less than or equal to the preset temperature value, and starting the refrigeration component will cause the temperature of the storage room to continue to drop, affecting the temperature control. Therefore, the refrigeration component and the second fan are controlled to be turned off. When there is a conflict between humidity control and temperature control, the temperature requirement is met first.

[0067] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.12 As shown, Fig.12 yes Fig.10 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S320 in FIG. 5 , wherein step S320 includes but is not limited to step S322.

[0068] Step S322, when the temperature value of the storage compartment 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.

[0069] It can be understood that when x>y+b, it indicates 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. The refrigeration component and the second fan continue to be in the on state, and the requirements of refrigeration and dehumidification are met 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 refrigeration state.

[0070] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.13 As shown, Fig.13 yes Fig.10 FIG. 5 is a schematic diagram of an embodiment of a detailed process of step S320 in FIG. 5 , wherein step S320 includes but is not limited to step S323.

[0071] Step S323: When the temperature value of the storage compartment is less than or equal to the preset temperature value and the refrigeration component is in the off state, the refrigeration component and the second fan are controlled to remain in the off state.

[0072] It is understandable that when x>y+b, it indicates that the humidity measurement 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 of the storage room is less than or equal to the preset temperature value, and starting the refrigeration component will cause the temperature of the storage room to continue to drop, affecting the temperature control, and the refrigeration component is currently in the off state. Therefore, the refrigeration component and the second fan are controlled to remain in the off state. When there is a conflict between humidity control and temperature control, the temperature requirement is given priority.

[0073] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.14 As shown, Fig.14 yes Fig.10 A schematic diagram of an embodiment of a detailed process of step S320 in FIG. 1 , wherein step S320 includes but is not limited to step S324.

[0074] Step S324, when the temperature value of the storage compartment is greater than the preset temperature value and the refrigeration component is in the off state, control the refrigeration component and the second fan to turn on.

[0075] It can be understood that when x>y+b, it indicates that the humidity measurement value x is greater than the required humidity setting value y. Normally, dehumidification is required, and the temperature value of the storage room is detected to be greater than the preset temperature value. Refrigeration is required to lower the temperature. The refrigeration component and the second fan are turned on to meet the requirements of refrigeration 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 refrigeration state.

[0076] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.15 As shown, Fig.15 yes Figure 6 FIG. 4 is a schematic diagram of an embodiment of a detailed process of step S300 in FIG. 4 , wherein step S300 includes but is not limited to step S330.

[0077] Step S330: when ya≤x≤y+b, the humidification component is controlled to be turned off.

[0078] It is understandable that when the set humidity is changed from the single point value y to the range value [ya, y+b], that is, when the humidity measurement value x falls within the range [ya, y+b], the compressor and the second fan do not need to be turned on, which can avoid frequent starting of the compressor and the second fan. The value of a can be a constant such as 8%, 5%, 3%, and the value of b can be a constant such as 8%, 5%, 3%. If the humidity setting value y is 60%, a is 5%, and b is 5%, when the humidity measurement value x is 50%, the humidification component needs to be turned on to supplement the high humidity airflow, and the refrigeration equipment enters the humidification mode; when the humidity measurement value x is 58%, the humidification component does not need to be turned on; when the humidity measurement value x is 80%, the humidification component needs to be turned off, and it is determined whether to turn on the refrigeration component for dehumidification based on the detected temperature value. When ya≤x≤y+b, if the storage room is in the cooling state, the speed of the second fan is R2 or R3; if the storage room is in the non-cooling state, the speed of the second fan is R1 or R2. When the humidity is sufficient, the second fan is turned on to improve the uniformity of temperature and humidity in the refrigeration equipment. The wind is constantly rotating to ensure that the upper and lower parts of the storage room have uniform temperature and humidity.

[0079] Another embodiment of the present invention also provides a control method for a refrigeration device, such as Fig.16 As shown, Fig.16 This is a complete embodiment of the control method for refrigeration equipment, which is described below in conjunction with specific steps.

[0080] Get the humidity setting value y and the humidity measurement value x, judge the humidity, confirm the range of humidity, control the working mode of the refrigeration equipment, and then perform corresponding control. When x<y-5, it indicates that the humidity of the storage space is low, and the refrigeration equipment is controlled to be in humidification mode. When x>y+5, it indicates that the humidity of the storage space is high, and the refrigeration equipment is controlled to be in dehumidification mode. When y-5≤x≤y+5, it indicates that the humidity of the storage space meets the requirements and humidity control is not required. The following describes in detail the specific control process of each humidity range combined with the temperature conditions.

[0081] When x<y-5, it is determined whether the refrigeration equipment is in the refrigeration stage. If the refrigeration equipment is in the refrigeration stage, the speed of the second fan is the same as that of the fan with the same temperature control specification 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. You can refer to Table 1 for the speed control table of the storage room in the refrigeration state, and turn on the humidification component. If the refrigeration equipment is not in the refrigeration stage, the second fan runs at the speed of R4 gear, that is, the speed of the second fan is increased to the maximum speed, and the humidification component is turned on until the humidity reaches the set humidity.

[0082] When x>y+5, it is determined whether the refrigeration equipment is in the refrigeration stage. If the refrigeration equipment is in the refrigeration stage, the speed of the second fan is the same as that of the fan with the same temperature control specification 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. You can refer to Table 1, the speed control table of the storage room in the refrigeration state, and turn on the humidification component. And it is determined in real time whether the temperature reaches the shutdown point, that is, whether the detected temperature value reaches the preset temperature value. If it reaches the shutdown point, the evaporator does not refrigerate, that is, the compressor is turned off, the second fan is not turned on, and the humidification component is not turned on. If the shutdown point is not reached, the evaporator continues to refrigerate, and the previous fan speed control strategy is continued. If the refrigeration equipment is not in the refrigeration stage, it is also necessary to determine whether the temperature reaches the shutdown point. If it does not reach the shutdown point, the evaporator starts to refrigerate, and the speed of the second fan is the same as that of the fan with the same temperature control specification under the same conditions. If it reaches the shutdown point, the evaporator does not refrigerate, that is, the compressor is turned off, the second fan is not turned on, and the humidification component is not turned on.

[0083] When y-5≤x≤y+5, the speed of the second fan is the same as that of the fan with temperature control specifications under the same conditions. You can refer to the speed control table in Table 1, where the storage room is in a non-refrigeration state (only executed when the humidity meets the requirements), and the humidification component is not turned on.

[0084] In the control strategies for the above three humidity ranges, it is finally necessary to read the new measurement value x in real time and then return to the step of judging the humidity.
