[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] Reference Figure 1 The diagram illustrates a dehumidification method for a storage system according to an embodiment of this application, which may include the following steps: Step 101: Obtain the food respiration rate of the food stored in the storage system, and the humidity information of the area in the storage system used to store the food.
[0029] In this embodiment of the application, in order to avoid accidental triggering of dehumidification, the dehumidification function can be triggered by combining the breathing status of the video stored in the storage system and the humidity status of the area where the food is stored.
[0030] In some embodiments, during operation, the storage system can collect data on the respiration of the food stored in the system to obtain the food respiration rate. For example, the storage system may include a food respiration rate sensor, which can be directly attached to the outer surface of the food to monitor its respiration and generate the food respiration rate (μL CO2·kg⁻¹). -1 ·h -1 ).
[0031] In some embodiments, during operation, the storage system can collect humidity data on the area where food is stored, thereby obtaining humidity information for that area. This humidity information may include the humidity value of the area where food is stored. For example, the storage system may include a humidity sensor, which can be used to monitor the humidity of the area where food is stored.
[0032] Humidity sensors can include food surface humidity sensors, humidity distribution sensor arrays, etc. Among them, food surface humidity sensors can be directly attached to the food surface to monitor the humidity of the food surface; humidity distribution sensor arrays can be evenly deployed at different horizontal positions on each shelf in the food storage area to detect the humidity in the horizontal direction of each shelf.
[0033] Step 102: Dehumidify the area based on the food's respiration rate and humidity information.
[0034] After obtaining information on the food's respiration rate and humidity, it is possible to determine whether to trigger the dehumidification function of the storage system based on this information. Compared to triggering the dehumidification function of the storage system solely based on humidity, this application can avoid accidental activation of the dehumidification function. This prevents the dehumidification function from being activated when the humidity is high but the respiration rate is low, thus avoiding wasting energy. It also prevents the dehumidification function from being deactivated when the humidity is low but the respiration rate is high, thus avoiding food spoilage.
[0035] For example, the storage system can be a refrigerator or other equipment for refrigerating and freezing food. Through the embodiments of this application, problems such as untimely dehumidification or excessive dehumidification in refrigerators can be avoided, and refrigerators can have energy-saving functions.
[0036] In this embodiment, the food respiration rate stored in the storage system and the humidity information of the area used for food storage in the storage system are obtained; based on the food respiration rate and humidity information, the area is dehumidified. Through this embodiment, the dehumidification function can be triggered by combining the respiration data of the video stored in the storage system with the humidity of the area where the food is stored, thereby avoiding problems such as untimely or excessive dehumidification.
[0037] Reference Figure 2 The diagram illustrates a flowchart of another dehumidification method for a storage system according to an embodiment of this application, which may include the following steps: Step 201: Obtain the food respiration rate of the food stored in the storage system, and the humidity information of the area in the storage system used to store the food; the humidity information includes the humidity values of different sub-areas in the area.
[0038] In this embodiment of the application, in order to avoid accidental triggering of dehumidification, the dehumidification function can be triggered by combining the breathing status of the video stored in the storage system and the humidity status of the area where the food is stored.
[0039] In some embodiments, during operation, the storage system can collect data on the respiration of the food stored in the storage system to obtain the food respiration rate of the food stored in the storage system.
[0040] In some embodiments, during operation, the storage system can collect humidity data of the area where food is stored, thereby obtaining humidity information for that area. For example, the humidity information may include humidity values for different sub-regions within the storage system. The division of sub-regions can be set according to actual conditions; for example, different sub-regions can be divided according to different vertical heights within the storage system. This embodiment does not impose such limitations.
[0041] Step 202: Determine the humidity non-uniformity of the area based on the humidity information.
[0042] After determining the humidity information, the humidity non-uniformity of the region can be determined based on the humidity values of different sub-regions within the region. Humidity non-uniformity indicates the degree of unevenness in humidity within a region; a higher value indicates greater humidity non-uniformity, with the existence of high-humidity and low-humidity sub-regions, and a larger difference in humidity values between these sub-regions. Conversely, a lower value indicates more uniform humidity within the region, with smaller differences in humidity values even if high-humidity and low-humidity sub-regions exist.
[0043] For example, we can first determine the humidity value with the highest value, the humidity value with the lowest value, and the average humidity value of multiple sub-regions from the humidity information; then, we can calculate the humidity non-uniformity using the following formula: Humidity unevenness = [(maximum humidity value - minimum humidity value) / average humidity value] × 100%.
[0044] Step 203: When the humidity non-uniformity is greater than the non-uniformity threshold and the food respiration rate is greater than the respiration rate threshold, the area is dehumidified.
[0045] After determining the humidity unevenness and food respiration rate, it is possible to determine whether to trigger the dehumidification function of the storage system based on the food respiration rate and humidity unevenness.
[0046] In some embodiments, the relationship between humidity non-uniformity and a preset non-uniformity threshold, and the relationship between food respiration rate and a preset respiration rate threshold can be determined.
[0047] If the humidity unevenness is greater than the unevenness threshold and the food respiration rate is greater than the respiration rate threshold, then it can be determined that the dehumidification function of the storage system needs to be activated; at this time, the area where the food is stored can be dehumidified.
[0048] Conversely, if the humidity unevenness is not greater than the unevenness threshold, or the food respiration rate is not greater than the respiration rate threshold, then it can be determined that the dehumidification function of the storage system does not need to be activated. In this case, new food respiration rate and humidity information can be obtained for a new round of judgment.
[0049] In some embodiments, after dehumidifying an area, the humidity unevenness can be re-acquired; if the humidity unevenness is detected to have dropped below a preset value, dehumidification of the area can be stopped. For example, dehumidification of the area can be stopped when the humidity unevenness drops to ≤2%.
[0050] In some other embodiments of this application, after determining that the dehumidification function of the storage system does not need to be turned on based on the humidity unevenness and food respiration rate, it can also be determined whether the average humidity value is greater than a certain value; for example, 85%. If the average humidity value is greater than this value, the step of dehumidifying the area can be directly performed to avoid excessive humidity.
[0051] In some embodiments of this application, the non-uniformity threshold can be determined in the following manner: Obtain historical humidity information and current environmental information for the region; determine the non-uniformity threshold based on the historical humidity information and current environmental information.
[0052] In some embodiments, the non-uniformity threshold can be automatically adjusted and determined based on historical data of the region, the current environment, etc., to achieve adaptive optimization.
[0053] For example, historical humidity information of the area where food is stored can be obtained first, such as the average humidity of the area over the past 30 days. Additionally, current environmental information about the location of the storage system can be obtained, including season, weather, humidity, and temperature.
[0054] After determining the historical humidity information and the current environmental information, the current non-uniformity threshold can be determined by combining the historical humidity information and the current environmental information.
[0055] For example, based on historical humidity information, a historical coefficient can be determined first; for instance: if the average humidity of the area over the past 30 days is >75%, the coefficient = 0.1; if the average humidity of the area over the past 30 days is ≤75%, the coefficient = 0. Since the air conditioner blows air, the ambient humidity determines the rate at which high-humidity areas form; the higher the humidity, the faster the high-humidity areas form, thus requiring a lower threshold.
[0056] Based on the current environmental information, different environmental coefficients can be set for different seasons and weather conditions; for example, summer (June-August) = 0.2, other seasons = 0. This current environmental information can also consider the seasonal impact of location; for example, in the north, summer (June-August) = 0.18, and in the south, summer (June-August) = 0.2. This application does not impose such limitations. Because humidity is generally high in summer, high-humidity zones in food areas form more quickly and severely, so the threshold is lowered for earlier intervention.
[0057] The environmental coefficient is a long-term seasonal characteristic, reflecting the inherent seasonal humidity characteristics of different regions, and can also change with the weather. In addition, a baseline value for the environmental coefficient can be preset for each region, based on the average humidity variability in summer (June-August) (humidity variability = average summer humidity / average annual humidity).
[0058] Variation rate > 1.2: Humidity is highly seasonal (high humidity areas require a higher coefficient), and the environmental coefficient benchmark value is preset to 0.25.
[0059] 0.9 < variability ≤ 1.2: moderate seasonality (medium humidity zone), the environmental coefficient baseline value is preset to 0.2.
[0060] Variation rate ≤ 0.9: Humidity seasonality is weak (low humidity area, lower coefficient), and the environmental coefficient benchmark value is preset to 0.15.
[0061] Historical coefficients are influenced by short-term weather conditions, and the dynamic impact of weather can be handled by historical coefficients, avoiding excessive dynamism in seasonal coefficients that could increase system complexity. The control mechanism, with a coefficient of 0.1 for average humidity > 75% and a coefficient of 0 for average humidity ≤ 75% over the past 30 days, already reflects the dynamic impact of weather: stricter controls for high humidity and more lenient controls for low humidity.
[0062] After determining the historical and environmental coefficients, a preset first baseline threshold can be calibrated based on these coefficients and environmental information to obtain the current non-uniformity threshold. For example, the current non-uniformity threshold can be calculated using the following formula: The current unevenness threshold = first basic threshold × (1 - seasonal coefficient × historical coefficient); The first basic threshold can be the benchmark value of the non-uniformity threshold, which can be set according to the actual situation, for example: 3%.
[0063] Example: In July 2025 (summer), the average humidity is 82%. The current non-uniformity threshold is 3% × (1 - 0.2 × 0.1) = 2.94% ≈ 2.9% (rounded to the nearest integer). By multiplying the seasonal coefficient by the historical coefficient, the threshold is ensured to be lowered only during periods of high humidity, while remaining at 3% in other scenarios. This avoids over-adjustment (such as false triggering during high humidity in spring) while ensuring timely response in high humidity scenarios.
[0064] In some embodiments of this application, the respiratory rate threshold can be determined in the following manner: Determine the food type, storage duration, and / or surface humidity of the food; determine the respiration rate threshold based on the food type, storage duration, and / or surface humidity.
[0065] In some embodiments, the respiration rates of different foods, foods stored for different durations, and foods with different humidity levels are different. In order to intervene in advance or avoid premature intervention, the respiration rate threshold can be determined based on the food type, the storage duration of the food, and / or the surface humidity of the food.
[0066] For example, one or more of the following information can be determined for the food: food type, food storage time, and food surface humidity.
[0067] The classification of food types can be set according to actual conditions; for example, based on moisture content, they can be divided into high-moisture foods and low-moisture foods. High-moisture foods can include strawberries, leafy green vegetables, etc., while low-moisture foods can include apples, dried fruits, etc. Another example is based on sensitivity to moisture, they can be divided into moisture-sensitive foods and moisture-sensitive foods. Moisture-sensitive foods can include dried goods, while moisture-sensitive foods can include root vegetables and fruits. This application does not impose any limitations on these classifications.
[0068] The storage time of food can refer to the length of time that food is stored in the storage system area; the respiration intensity of food is different after different storage times, and based on this, it can also be used to determine the respiration rate threshold.
[0069] The surface humidity of food can be measured using a food surface humidity sensor, which indicates the humidity value of the food surface.
[0070] In some embodiments, the respiratory rate threshold can be determined based on food type; for example, food type coefficients can be set for different food types; then, the current respiratory rate threshold can be calculated based on the following formula: Respiratory rate threshold = Second baseline threshold × (1 - food type coefficient); The second basic threshold can be set according to the actual situation; it can be a baseline value, for example, 50 μL CO2·kg.-1 ·h -1 .
[0071] In other embodiments, the respiration rate threshold can be determined based on the storage time of the food; for example, strawberries have a high respiration rate in the early stages of refrigeration, which gradually decreases over time (due to reduced ethylene production or slower metabolism). Therefore, the longer the storage time, the more lenient the threshold may need to be (i.e., a smaller coefficient, because the risk is lower due to the reduced respiration rate).
[0072] In another embodiment, the respiration rate threshold can be determined based on surface humidity; for example, when surface humidity > 80%, the respiration rate threshold can be dynamically reduced by 5 μL CO2·kg. -1 ·h -1 .
[0073] In some embodiments, the respiration rate threshold may also be determined based on at least two of the following: food type, storage duration, and surface humidity.
[0074] For example, the effective coefficient corresponding to the food type coefficient can be set to decrease with the number of days (the coefficient decreases linearly with the number of days, with a decrease rate of 0.03 / day). Then, the respiratory rate threshold can be calculated using the following formula: Respiratory rate threshold = Second baseline threshold × (1 - effective coefficient); Effective coefficient = food type coefficient × (1 - 0.03 × (shelf life - 1)).
[0075] In another example, after determining the respiration rate threshold based on food type and storage duration, if surface humidity is detected to be greater than 80%, the respiration rate threshold can be directly reduced to 5 μL CO2·kg⁻¹. -1 ·h -1 However, the embodiments in this application do not impose any limitations on this.
[0076] In this embodiment, the food respiration rate of the food stored in the storage system and the humidity information of the area used for food storage in the storage system are obtained. The humidity information includes the humidity values of different sub-areas within the area. Based on the humidity information, the humidity non-uniformity of the area is determined. When the humidity non-uniformity is greater than a non-uniformity threshold and the food respiration rate is greater than a respiration rate threshold, the area is dehumidified. Through this embodiment, historical data, environmental information, food type, storage time, surface humidity, etc., can be integrated to adaptively adjust the threshold, thereby triggering the dehumidification function of the storage system more accurately.
[0077] Reference Figure 3 The diagram illustrates a flowchart of another dehumidification method for a storage system according to an embodiment of this application, which may include the following steps: Step 301: Obtain the food respiration rate of the food stored in the storage system, and the humidity information of the area in the storage system used to store the food.
[0078] In this embodiment of the application, in order to avoid accidental triggering of dehumidification, the dehumidification function can be triggered by combining the breathing status of the video stored in the storage system and the humidity status of the area where the food is stored.
[0079] In some embodiments, during operation, the storage system can collect data on the respiration of the food stored in the storage system to obtain the food respiration rate of the food stored in the storage system.
[0080] In some embodiments, during operation, the storage system can collect data on the humidity of the area where food is stored, thereby obtaining humidity information of that area.
[0081] Step 302: Determine the humidity non-uniformity of the area based on the humidity information.
[0082] After determining the humidity information, the humidity non-uniformity of the region can be determined based on the humidity values of different sub-regions within the region.
[0083] For example, the humidity value with the highest value, the humidity value with the lowest value, and the average humidity value of multiple sub-regions can be determined from the humidity information first; then, the humidity non-uniformity can be determined based on the highest humidity value, the lowest humidity value, and the average humidity value of multiple sub-regions.
[0084] Step 303: Determine the direction of the humidity gradient in the area based on the humidity information.
[0085] In some embodiments, after determining the humidity information, the direction of the humidity change gradient in the region can be determined based on the humidity values of different sub-regions in the humidity information; the direction of the change gradient can refer to the direction from the sub-region with high humidity to the sub-region with low humidity.
[0086] Step 304: When the humidity non-uniformity is greater than the non-uniformity threshold and the food respiration rate is greater than the respiration rate threshold, blow air from the high humidity sub-region to the low humidity sub-region along the gradient direction.
[0087] After determining the humidity unevenness and food respiration rate, it is possible to determine whether to trigger the dehumidification function of the storage system based on the food respiration rate and humidity unevenness.
[0088] In some embodiments, the relationship between humidity non-uniformity and a preset non-uniformity threshold, and the relationship between food respiration rate and a preset respiration rate threshold can be determined.
[0089] If the humidity unevenness is greater than the unevenness threshold and the food respiration rate is greater than the respiration rate threshold, then it can be determined that the dehumidification function of the storage system needs to be activated; at this time, the area where the food is stored can be dehumidified.
[0090] Conversely, if the humidity unevenness is not greater than the unevenness threshold, or the food respiration rate is not greater than the respiration rate threshold, then it can be determined that the dehumidification function of the storage system does not need to be activated. In this case, new food respiration rate and humidity information can be obtained for a new round of judgment.
[0091] When dehumidifying an area, air can be blown from the high-humidity sub-area to the low-humidity sub-area along the direction of the changing gradient, thereby blowing water vapor from the high-humidity sub-area to the low-humidity sub-area and accelerating water evaporation.
[0092] In some embodiments of this application, step 304 can be implemented by the following sub-steps: Sub-step 11: Determine the type of food and, based on the type of food, determine the airflow pattern.
[0093] In some embodiments, different airflow patterns can be used for blowing based on the type of food in the area.
[0094] For example, high-moisture foods can be moistened using a pulse method; for strawberries, a pulse method can be used, blowing for 10 seconds and then stopping for 5 seconds.
[0095] For low-moisture foods, such as dried fruits, a continuous blowing method can be used; blow at a speed of 0.1-0.5 m / s along the direction of the humidity gradient.
[0096] Sub-step 12: According to the airflow pattern, blow air from the high humidity sub-region to the low humidity sub-region along the direction of the changing gradient.
[0097] After determining the airflow pattern, air can be blown from the high-humidity sub-region to the low-humidity sub-region along the changing gradient direction, according to the airflow pattern. For example, if the airflow pattern is pulsed, air can be blown from the high-humidity sub-region to the low-humidity sub-region along the changing gradient direction, blowing for 10 seconds and then stopping for 5 seconds.
[0098] In another example, if the airflow pattern is continuous, air can be continuously blown from a high-humidity sub-region to a low-humidity sub-region along the changing gradient direction.
[0099] In some embodiments of this application, when blowing air from a high-humidity sub-region to a low-humidity sub-region along the changing gradient direction, the above embodiments may further include the following steps: Sub-step 21: Reduce the speed of the air cooler in the storage system; and / or reduce the cooling power of the condenser in the storage system.
[0100] In this embodiment of the application, the storage system may further include a cooler and a condenser; wherein, the condenser is the core of the storage system and can be used to condense the refrigerant; the cooler can be used to provide cold airflow to promote uniform cooling.
[0101] In some embodiments, when blowing air from a high-humidity sub-region to a low-humidity sub-region along the changing gradient direction, the speed of the storage system's air cooler can be reduced to avoid the airflow of the air cooler interfering with the directional blowing during dehumidification.
[0102] In other embodiments, when air is blown from a high-humidity sub-region to a low-humidity sub-region along the changing gradient direction, the overall dehumidification load is reduced due to the decrease in local humidity. In this case, the cooling power of the condenser can be reduced to save energy.
[0103] For example, when the airflow actuator is started, the storage system can simultaneously perform the following actions: 1. Reduce the speed of the evaporative air cooler to 50% of its original speed (controlled by the frequency converter) to avoid the airflow of the evaporative air cooler interfering with the directional blowing of the micro airflow, and reduce the speed to ensure the effectiveness of the micro airflow; 2. Reduce the condenser's cooling power to 90% of its original power (by adjusting the compressor frequency). The overall dehumidification load is reduced due to the decrease in local humidity, resulting in energy savings. If the temperature gradient is greater than 1°C, the start-up speed range of the airflow actuator will dynamically increase to 0.3–0.5 m / s. Temperature gradient is a cause of respiratory rate fluctuations. An increase in temperature gradient leads to more severe respiratory rate fluctuations, resulting in continuous humidity accumulation in low-temperature areas. The airflow actuator needs to increase its speed and respond more quickly to avoid exacerbating the high-humidity areas (such as condensation in low-temperature areas).
[0104] When surface humidity exceeds 80%, the system automatically and dynamically reduces the respiration rate threshold by 5 μL CO2·kg. -1 ·h -1 Food surface humidity is a direct cause of respiratory rate fluctuations. Increased food surface humidity makes food more prone to spoilage, so it is necessary to lower the respiratory rate threshold and trigger micro-airflow earlier.
[0105] During micro-airflow operation, the system calculates the rate of decline in respiratory rate. The duration of the airflow actuator is based on the rate of decline in respiratory rate; when the rate of decline in respiratory rate > 15% / min, the duration of the airflow actuator is shortened to 2-3 minutes. The rate of decline in respiratory rate reflects the effectiveness of the micro-airflow; a higher rate of decline in respiratory rate indicates a better micro-airflow effect. When the effect is good, the duration is shortened to avoid excessive blowing and wasting energy, thus saving energy and reducing costs.
[0106] When the humidity distribution unevenness drops to ≤2%, the system automatically shuts down the airflow actuator.
[0107] In some embodiments of this application, the storage system includes an airflow actuator for blowing air along a changing gradient direction from a high-humidity sub-region to a low-humidity sub-region within the region; based on this, the above embodiments may further include the following steps: Determine the temperature gradient of the area; adjust the start-up speed of the airflow actuator based on the temperature gradient.
[0108] In this embodiment of the application, the storage system may include an airflow actuator that can be used to blow air along a changing gradient direction from a high-humidity sub-region to a low-humidity sub-region in order to reduce local humidity.
[0109] In some embodiments, because cold air is denser and naturally sinks, there are significant differences in temperature along the vertical direction. Therefore, a temperature gradient sensor array can be deployed in the storage system to monitor the temperature gradient along the height of each layer. The temperature gradient can be calculated using the following formula: Temperature gradient = (Upper temperature - Lower temperature) / Vertical height difference; The vertical height difference can be the height difference between the corresponding positions of the upper and lower temperatures; the upper temperature can be the temperature of the upper layer in the region, and the lower temperature can be the temperature of the lower layer in the region.
[0110] In some embodiments, temperature gradient is the cause of respiratory rate fluctuations. An increase in temperature gradient leads to more severe respiratory rate fluctuations, which in turn leads to continuous accumulation of humidity in low-temperature areas. In response, airflow actuators need to accelerate and respond faster to avoid the deterioration of high-humidity areas (such as condensation in low-temperature areas).
[0111] Based on this, after determining the temperature gradient, this application can adjust the start-up speed of the airflow actuator according to the temperature gradient. For example, if the temperature gradient is >1°C, the start-up speed range of the airflow actuator can be dynamically increased to 0.3-0.5 m / s, and this application does not limit this.
[0112] In some embodiments of this application, the above embodiments may further include the following steps: Based on the food's respiration rate, determine the rate of decrease in respiration rate; based on the rate of decrease in respiration rate, determine the duration of operation of the airflow actuator.
[0113] In some embodiments, after determining the food respiration rate, the rate of decrease in respiration rate can be determined based on the food respiration rate at different time periods.
[0114] The rate of decrease in breathing rate reflects the dehumidification effect. The higher the rate of decrease in breathing rate, the better the effect. When the effect is good, the time can be shortened, which can avoid excessive blowing and wasting energy, thus saving energy and reducing costs.
[0115] Based on this, this application can determine the duration of operation of the airflow actuator according to the rate of decline in respiratory rate; for example, when the rate of decline in respiratory rate is >15% / min, the duration of the airflow actuator can be shortened to 2-3 minutes. That is, the operation of the airflow actuator can be turned off after 2-3 minutes of operation.
[0116] In this embodiment, the respiration rate of food stored in the storage system and the humidity information of the area used for food storage in the storage system are obtained. Based on the humidity information, the humidity non-uniformity of the area is determined. Based on the humidity information, the direction of the humidity change gradient in the area is determined. When the humidity non-uniformity is greater than the non-uniformity threshold and the food respiration rate is greater than the respiration rate threshold, air is blown from the high-humidity sub-area to the low-humidity sub-area along the change gradient direction. Through this embodiment, the dehumidification function can be triggered by combining the respiration status of the video stored in the storage system and the humidity status of the area where the food is stored, thereby avoiding problems such as untimely dehumidification or over-dehumidification.

However, those skilled in the art should understand that the embodiments of this application are not limited to the described order of actions, because according to the embodiments of this application, some steps can be performed in other orders or simultaneously.

[0118] Reference Figure 4 A simplified structural diagram of a storage system according to an embodiment of this application is shown; as follows: Figure 4 As shown, the storage system 40 may include: Cold storage 410 has an area for storing food; Airflow actuator 420, deployed in the area; Control device 430 is used to acquire the food respiration rate of the food stored in storage system 40 and the humidity information of the area in storage system 40 used for storing food; based on the food respiration rate and humidity information, control airflow actuator 420 to dehumidify the area.
[0119] In this embodiment of the application, the storage system 40 may consist of at least a cold storage 410, an airflow actuator 420, and a control device 430; wherein, the cold storage 410 may be provided with an area for storing food; in addition, the storage system 40 may also include a refrigeration subsystem for reducing the temperature of the area of the cold storage 410, thereby providing a suitable storage environment for the food in the area.
[0120] The airflow actuator 420 can be deployed in the area and controlled by the control device 430 for dehumidifying the area.
[0121] The control device 430 can be connected to the airflow actuator 420 and is used to acquire the food respiration rate of the food stored in the storage system 40. Additionally, the control device 430 can also acquire humidity information of the area in the storage system 40 where the food is stored.
[0122] After obtaining the food's respiration rate and humidity information, the control device 430 can determine whether to trigger the dehumidification function of the storage system 40 based on the food's respiration rate and humidity information.
[0123] If it is determined that the dehumidification function needs to be triggered, the control device 430 may start the airflow actuator 420; if it is determined that the dehumidification function does not need to be triggered, the control device 430 may not start the airflow actuator 420.
[0124] It should be noted that the control device 430 can also be used to perform any one of the steps in the above method embodiments, which will not be described again in this application.

[0127] The control device 430 can be used to control the motor 431, thereby driving the fan 432 to rotate, and thus blowing air from the high humidity sub-region to the low humidity sub-region along the changing gradient direction.
[0128] In some embodiments, in order to achieve precise dehumidification, the angle of the adjustable guide vane 433 can be adjusted by the motor 431; the control device 430 can adjust the angle of the adjustable guide vane 433 by controlling the motor 431, thereby adjusting the airflow direction of the fan 432 outlet so that the airflow is directed to the high humidity sub-area.
[0129] Reference Figure 6 The diagram shows a structural schematic of a storage system 40 according to an embodiment of this application; as shown Figure 6 As shown: The storage system 40 may include a housing; a cold storage 410, an airflow actuator 420 and a control device 430 may be installed in the housing; the storage system 40 may also be provided with a condenser 440 for condensation and dehumidification.
[0130] Reference Figure 7 , showed Figure 6 A schematic diagram of the AA' cross-section; as shown Figure 7 As shown: Storage system 40 may include at least a condenser 440, an air cooler 450, a cold storage 410, an airflow actuator 420, and shelves 460; shelves may include multiple (see reference). Figure 7 It may include a first shelf 460 (1) and a second shelf 460 (2); food may be placed on the shelf.
[0131] The air cooler 450 can be used to circulate cold air in the food storage area of the cold storage 410; the first shelf 460 (1) and the second shelf 460 (2) can be arranged in parallel in the food storage area of the cold storage 410.
[0132] The shelf 460 may have grid ventilation holes, and the airflow actuator 420 may be deployed on the lower surface of the shelf; thus, the airflow actuator 420 can blow air from bottom to top onto the food on the shelf 460, thereby dispersing the humid air and achieving dehumidification.
[0133] Reference Figure 8 The following is a flowchart illustrating the steps of a dehumidification method for a storage system according to an embodiment of this application: First, detection can begin to obtain information on food respiration rate and humidity. In addition, based on the integration of historical humidity information, food type and current environmental information, the unevenness threshold and respiration rate threshold can be dynamically adjusted, and it can be determined whether the food respiration rate is greater than the respiration rate threshold and whether the humidity unevenness is greater than the unevenness threshold.
[0134] If the food's respiration rate is not greater than the respiration rate threshold, or the humidity unevenness is not greater than the unevenness threshold, the test can be repeated.
[0135] Conversely, if the food's respiration rate exceeds the respiration rate threshold and the humidity unevenness exceeds the unevenness threshold, the airflow actuator can be activated, and the condenser and air cooler can be adjusted accordingly. It can also be determined whether the temperature gradient is greater than 1°C.
[0136] When the temperature gradient is greater than 1℃, the starting speed range of the airflow actuator can be increased to 0.3-0.5m / s; conversely, if the temperature gradient is not greater than 1℃, the starting speed range of the airflow actuator can be 0.1-0.5m / s.
[0137] In addition, the type of food can be determined; if it is a low-moisture food, the airflow actuator can be controlled to blow air in a continuous airflow mode. If it is a high-moisture food, the airflow actuator can be controlled to blow air in a pulsed airflow mode.
[0138] After the airflow actuator has been running for a period of time, it can be determined whether the rate of decrease in respiratory rate is greater than 15% / min. If so, the running time of the airflow actuator can be shortened to 2-3 minutes. Conversely, if the rate of decrease in respiratory rate is not greater than 15% / min, the airflow actuator can continue to run.
[0139] When the detected humidity non-uniformity is less than or equal to 2%, the airflow actuator can be turned off.
[0140] This application integrates historical humidity information, food type and current environmental information to dynamically adjust the non-uniformity threshold and breathing rate threshold, and establishes a closed-loop causal chain of temperature gradient, breathing rate fluctuation and airflow acceleration to achieve directional blowing and speed / mode / duration adaptation of the airflow actuator.
[0141] In addition, the synchronous linkage between the speed reduction of the air cooler and the power adjustment of the condenser extends the shelf life of food and reduces equipment energy consumption, solving the problems of blind spots in monitoring, rigid thresholds and inefficient execution in traditional cold storage preservation.
