Description

Technical Field

[0001] The present application relates to the technical field of refrigerator adjustment, and in particular to a method, device, equipment and storage medium for adjusting energy consumption of a refrigerator. Background Art

[0002] Energy consumption regulation is an important issue in the use of modern refrigerators. Refrigerator cabinets are usually divided into multiple areas, each area is used to store different types and quantities of items. In order to ensure the quality and freshness of the items, the refrigerator needs to adjust the temperature according to the characteristics of the items in different areas. However, how to achieve energy-saving operation of the refrigerator while ensuring the quality of the items has become a technical problem that needs to be solved urgently.

[0003] At present, the energy-saving operation of refrigerators is achieved by controlling the compressor of the refrigerator to stop running, so that the temperature of each storage area in the refrigerator slowly rises to a certain temperature, and then restarting the compressor to cool down. This method can reduce the frequent startup of the compressor to a certain extent, thereby reducing energy consumption. Then, after the compressor stops, the temperature in the refrigerator will gradually rise until it reaches a certain upper limit temperature, and then the compressor will be restarted to cool down. This will cause large temperature fluctuations in the refrigerator, which may affect the quality and freshness of the stored items. Summary of the invention

[0004] The present application provides a method, device, equipment and storage medium for regulating energy consumption of a refrigerator, which are used to achieve energy-saving operation of the refrigerator while ensuring the quality of goods.

[0005] In a first aspect, the present application provides a method for regulating energy consumption of a refrigerator, the method comprising: obtaining the number and types of items stored in multiple areas of the refrigerator; determining a target refrigeration temperature range for each of the areas based on the number and types of items; obtaining the energy-saving refrigeration temperature of each of the areas when it is in energy-saving mode; adjusting the refrigeration temperature of a first area to the energy-saving refrigeration temperature, the energy-saving refrigeration temperature of the first area being within the target refrigeration temperature range; adjusting the refrigeration temperature of a second area to a target refrigeration temperature, the energy-saving refrigeration temperature of the second area being not within the refrigeration temperature range, the target refrigeration temperature being the temperature with the lowest energy consumption in the target refrigeration temperature range.

[0006] By adopting the above technical solution, the number and types of items stored in multiple areas of the refrigerator are obtained, and the target refrigeration temperature range of each area is determined based on this information. The refrigeration temperature of each area can be customized according to the characteristics of the actual stored items to ensure that the items are stored at the most suitable temperature, thereby maximizing their quality and freshness. For the first area, when its energy-saving refrigeration temperature is in the target refrigeration temperature range, its refrigeration temperature is adjusted to the energy-saving refrigeration temperature. For the second area, if its energy-saving refrigeration temperature is not in the target refrigeration temperature range, its refrigeration temperature is adjusted to the temperature with the lowest energy consumption in the target refrigeration temperature range. In the case where the energy-saving refrigeration temperature cannot be directly applied, it is still possible to achieve the lowest possible energy consumption by selecting the target refrigeration temperature with the lowest energy consumption, while ensuring that the items are stored within a suitable temperature range. In summary, energy-saving operation of the refrigerator is achieved while ensuring the quality of the items.

[0007] Optionally, after adjusting the refrigerated temperature of the second area to the target refrigerated temperature, the method further includes: obtaining the influence coefficient of the first area on the refrigerated temperature of the second area; calculating the difference between the energy-saving refrigerated temperature of the first area and the target refrigerated temperature of the second area; when the difference is greater than a threshold, adjusting the refrigerated temperature of the first area and / or the second area according to the influence coefficient.

[0008] By adopting the above technical solution, the influence coefficient of the first area on the refrigerated temperature of the second area is obtained. Then, the difference between the energy-saving refrigerated temperature of the first area and the target refrigerated temperature of the second area is calculated. If the difference is greater than the preset threshold, the refrigerated temperature of the first area and / or the second area is adjusted according to the influence coefficient. Not only is the personalized adjustment of the refrigerated temperature of each area ensured, the quality and freshness of the stored items are guaranteed, but also the efficient operation of the refrigerator is achieved in the energy-saving mode. In particular, by calculating the temperature difference between different areas and adjusting it according to the influence coefficient, the problems of temperature fluctuation and uneven distribution can be effectively reduced, thereby improving the stability and energy efficiency of the overall system.

[0009] Optionally, determining the target refrigerated temperature range for each of the areas based on the number of items and the types of items includes: sorting each of the item types from large to small according to the number of items in each of the item types to obtain a target sequence; obtaining standard refrigerated temperature ranges corresponding to multiple item types that are before a preset position in the target sequence, and using an intersection range between the standard refrigerated temperature ranges corresponding to the multiple item types as the target refrigerated temperature range for each of the areas.

[0010] By adopting the above technical solution and comprehensively considering the number and types of items, it is ensured that the target refrigeration temperature range can meet the refrigeration needs of most items, thereby improving the rationality and accuracy of the temperature setting. Secondly, by taking the intersection interval of the standard refrigeration temperature ranges of multiple types of items, the conflict of temperature requirements of different items is avoided, ensuring the coordination and unification of the refrigeration environment. In addition, under the premise of meeting the refrigeration needs, by reasonably determining the target refrigeration temperature range, energy consumption can be effectively reduced and the energy efficiency of the refrigerator can be improved. At the same time, precise temperature control and reasonable temperature range settings can help maintain the freshness and quality of refrigerated items and extend the shelf life of items. Finally, through reasonable temperature range settings, the problems of temperature fluctuations and uneven distribution are reduced, and the stability and overall operation efficiency of the refrigeration system are improved.

[0011] Optionally, after obtaining the standard refrigerated temperature intervals corresponding to the multiple item types before the preset position in the target sequence, the method further includes: if there is no intersection interval between the standard refrigerated temperature intervals corresponding to the multiple item types before the preset position in the third area, then the standard refrigerated temperature interval corresponding to the first item type at the first position in the target sequence is used as the first target refrigerated temperature interval; sequentially obtaining the standard refrigerated temperature intervals corresponding to the multiple item types after the first position in the target sequence; determining whether the difference between the boundary value of the first target refrigerated temperature interval and the boundary value of the standard refrigerated temperature interval corresponding to the multiple item types is less than a preset threshold; if it is not less than the preset threshold, then eliminating the standard refrigerated temperature intervals corresponding to the items that are not less than the preset threshold; if it is less than the preset threshold, then taking the union of the first target refrigerated temperature interval and the standard refrigerated temperature intervals corresponding to the items that are less than the preset threshold as the target refrigerated temperature interval for the third area.

[0012] By adopting the above technical solution, when there is no intersection between the standard refrigerated temperature intervals of multiple types of items in the third area, the standard refrigerated temperature interval of the item type in the first position in the target sequence is selected as the first target refrigerated temperature interval, thereby ensuring the initial rationality and priority of the temperature interval. Then, by gradually adjusting and judging the boundary values ​​of the standard refrigerated temperature intervals of adjacent item types and comparing them with the first target refrigerated temperature interval, the problem that direct selection may cause the temperature interval to be too large or too small is avoided. Furthermore, by eliminating the standard refrigerated temperature intervals of item types that do not meet the preset threshold, the accuracy and applicability of the target refrigerated temperature interval finally determined are guaranteed. Finally, by taking the union of the standard refrigerated temperature intervals of the item types that meet the preset threshold and the first target refrigerated temperature interval as the target refrigerated temperature interval of the third area, the optimization and balance of the temperature setting are achieved, ensuring that the refrigerator meets the refrigeration needs of different types of items while improving the overall energy efficiency and stability of the system.

[0013] Optionally, obtaining the energy-saving refrigeration temperature of each of the areas when the area is in the energy-saving mode includes: measuring and recording the refrigeration temperature change curve of each of the areas after entering the energy-saving mode; determining the temperature value after the refrigeration temperature change curve tends to be stable based on the refrigeration temperature change curve; and using the temperature value after each of the refrigeration temperature change curve tends to be stable as the energy-saving refrigeration temperature of each of the areas.

[0014] By adopting the above technical solution, by measuring and recording the refrigeration temperature change curve of each area after entering the energy-saving mode, the temperature change of the refrigerator in the energy-saving mode can be grasped in real time. This process provides detailed temperature data, which provides a solid foundation for subsequent temperature evaluation and optimization. Secondly, by analyzing and determining the temperature value after the refrigeration temperature change curve tends to be stable, the stable operation state of the refrigerator in the energy-saving mode can be effectively identified. The stable temperature value reflects the optimal temperature setting of the refrigerator under low energy consumption conditions, ensuring the refrigeration effect while minimizing energy consumption. Using these stable temperature values ​​as the energy-saving refrigeration temperature of each area can not only optimize the overall energy efficiency of the refrigerator, but also find a balance between items with different temperature requirements, ensuring that the refrigeration needs of each area are met.

[0015] Optionally, the method further includes: real-time monitoring of the actual refrigerated temperature of each of the areas; determining whether the actual refrigerated temperature exceeds the target refrigerated temperature range of the corresponding area; if it exceeds the target refrigerated temperature range of the corresponding area, sending an alarm message to the user end.

[0016] By adopting the above technical solution, the temperature changes in each area of ​​the refrigerator can be instantly grasped by real-time monitoring of the actual refrigeration temperature of each area. The real-time and accuracy of the temperature data is ensured, providing a reliable basis for subsequent judgment and processing. By judging whether the actual refrigeration temperature exceeds the target refrigeration temperature range of the corresponding area, temperature abnormalities can be discovered in time. The target refrigeration temperature range is determined comprehensively based on the refrigeration needs and energy-saving requirements of the items. Keeping the actual temperature within this range can ensure the best balance between refrigeration effect and energy efficiency.

[0017] In a second aspect, the present application provides an energy consumption adjustment device for a refrigerator, the device comprising: a first acquisition module, a determination module, a second acquisition module, a first adjustment module and a second adjustment module; wherein the first acquisition module is used to obtain the number and types of items stored in multiple areas of the refrigerator; the determination module is used to determine the target refrigeration temperature range of each of the areas based on the number and types of items; the second acquisition module is used to obtain the energy-saving refrigeration temperature of each of the areas when it is in energy-saving mode; the first adjustment module is used to adjust the refrigeration temperature of the first area to the energy-saving refrigeration temperature, the energy-saving refrigeration temperature of the first area being in the target refrigeration temperature range; the second adjustment module is used to adjust the refrigeration temperature of the second area to the target refrigeration temperature, the energy-saving refrigeration temperature of the second area is not in the refrigeration temperature range, and the target refrigeration temperature is the temperature with the minimum energy consumption in the target refrigeration temperature range.

[0027] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0029] Figure 1 is a flow chart of a method for adjusting energy consumption of a refrigerator provided in an embodiment of the present application. It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but the steps are not necessarily executed in the order indicated by the arrows; unless otherwise specified in this document, there is no strict order restriction for the execution of the steps, and the steps may be executed in other orders; and Figure 1 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0030] The present application discloses a method for regulating energy consumption of a refrigerator, such as Figure 1 As shown, the method includes S101-S105.

[0031] S101, obtaining the quantity and types of items stored in multiple areas of the refrigerator.

[0032] Specifically, multiple zones are different temperature control areas inside the refrigerator, which can be divided according to the type of items, storage requirements and the design structure of the refrigerator. For example, a refrigerator may be divided into a freezing area, a refrigeration area, a fruit and vegetable preservation area, and a meat preservation area, etc. Each area has an independent temperature control system to meet the storage requirements of different items.

[0033] In one example, because different items have different requirements for refrigeration temperature, and the number of items will affect the temperature distribution inside the refrigerator. In order to achieve energy consumption optimization, it is necessary to accurately understand the information of the items in each area so as to subsequently determine the target refrigeration temperature range and energy-saving refrigeration temperature of each area.

[0034] In specific implementation, it can be done through sensor and tag technology. Sensors are installed in multiple areas of the refrigerator, and each item is equipped with a corresponding RFID tag or QR code. The sensor can read the tag information in real time to obtain the type and quantity of items stored in each area. The data collected by the sensor is transmitted wirelessly to the central control system. The system processes and counts the data and generates a detailed report on the number and type of items in each area. The report will serve as the basic data for subsequent temperature adjustment. In order to ensure the accuracy of the data, the system needs to be calibrated and updated regularly. For example, the sensor should be calibrated regularly to ensure the accuracy of the data it reads; the data should be updated in time when the items enter and leave the refrigerator to reflect the latest storage status of the items.

[0035] S102, determining a target refrigeration temperature range for each area according to the quantity and type of items.

[0036] In one example, different types and quantities of items have different requirements for refrigeration temperature. Precise temperature control can ensure the freshness of the items while optimizing energy consumption.

[0037] In the specific implementation, the data of the number and type of items obtained in step S101 need to be input into the central control system. The system includes a preset database, which stores the optimal storage temperature range of various items. For example, the optimal storage temperature of vegetables and fruits is usually between 1°C and 5°C, while the optimal storage temperature of meat is between -2°C and 2°C. The system will calculate the target refrigeration temperature range of each area based on the item data of each area and match it with the optimal storage temperature in the database.

[0038] Next, consider the number of items. More items may generate more heat and require a slightly lower temperature to maintain a stable refrigerated environment. Through statistical analysis of the number of items, the target temperature range can be refined. For example, if there are fewer items in a certain area, the temperature in that area can be slightly higher than the standard storage temperature to save energy; conversely, if there are more items, the temperature needs to be lowered to ensure that all items can be evenly refrigerated.

[0039] After the system finally determines the target refrigeration temperature range for each area, it will send these target temperature range instructions to the corresponding temperature control equipment to adjust the refrigeration temperature of each area. This ensures that the temperature of each area is within the optimal range suitable for the items stored there, thereby ensuring the freshness of the items.

[0040] Based on the above embodiment, as an optional implementation, in S102, determining the target refrigeration temperature range of each area according to the number of items and the type of items specifically includes the following steps:

[0041] S20, according to the quantity of each item type, sort each item type in descending order according to the quantity, to obtain a target sequence.

[0042] S21, obtaining standard refrigeration temperature intervals corresponding to multiple types of goods before a preset position in the target sequence, and taking the intersection interval between the standard refrigeration temperature intervals corresponding to the multiple types of goods as the target refrigeration temperature interval of each area.

[0043] In one example, the target sequence and preset position are determined, and the order of arrangement of items in the refrigerator, that is, the target sequence, is determined. For example, the target sequence is: [apple, carrot, milk], and the preset position is the second position (that is, the position of carrot). Extract the item type and the standard refrigeration temperature range, and obtain multiple item types before the preset position in the target sequence. In this example, the item type before the preset position is [apple]. Query the standard refrigeration temperature range corresponding to each item. For example: the standard refrigeration temperature range for apples is 1°C to 4°C, and the standard refrigeration temperature range for carrots is 0°C to 5°C. Calculate the intersection interval, and use the intersection interval between the standard refrigeration temperature ranges corresponding to multiple item types as the target refrigeration temperature range for each area. In this example, the intersection interval of the standard refrigeration temperature ranges of apples and carrots is 1°C to 4°C.

[0044] The target refrigerated temperature interval is set, and the calculated intersection interval is set as the target refrigerated temperature interval of each area. That is, in this example, 1°C to 4°C is set as the target refrigerated temperature interval of each area.

[0045] After obtaining the standard refrigeration temperature ranges corresponding to the multiple types of items before the preset position in the target sequence, the following steps are also included:

[0046] If there is no intersection between the standard refrigerated temperature intervals corresponding to the multiple item types before the preset position in the third area, the standard refrigerated temperature interval corresponding to the first item type at the first position in the target sequence is used as the first target refrigerated temperature interval;

[0047] Sequentially obtaining standard refrigeration temperature intervals corresponding to a plurality of types of items after the first position in the target sequence;

[0048] Determine whether the difference between the boundary value of the first target refrigerated temperature range and the boundary value of the standard refrigerated temperature range corresponding to multiple types of items is less than a preset threshold; if it is not less than the preset threshold, the standard refrigerated temperature range corresponding to the items not less than the preset threshold will be eliminated; if it is less than the preset threshold, the union of the first target refrigerated temperature range and the standard refrigerated temperature range corresponding to the items less than the preset threshold will be used as the target refrigerated temperature range for the third area.

[0049] In one example, when there is no intersection between the standard refrigerated temperature intervals, the following steps are performed: the standard refrigerated temperature interval corresponding to the first item type at the first position in the target sequence is used as the first target refrigerated temperature interval. In this example, the item type at the first position is apple, and its standard refrigerated temperature interval is 1°C to 4°C. Therefore, 1°C to 4°C is set as the first target refrigerated temperature interval. The standard refrigerated temperature intervals corresponding to multiple item types after the first position in the target sequence are obtained in sequence. In this example, the standard refrigerated temperature interval of bananas, 12°C to 14°C, is obtained. It is determined whether the difference between the boundary value of the first target refrigerated temperature interval and the boundary value of the standard refrigerated temperature interval corresponding to multiple item types is less than a preset threshold. Assuming that the preset threshold is 10°C: compare the difference between the upper limit value of the first target refrigerated temperature interval 4°C and the lower limit value of the banana standard refrigerated temperature interval 12°C, and find that the difference between 4°C and 12°C is 8°C, which is less than the preset threshold 10°C. The union of the standard refrigerated temperature intervals corresponding to items less than the preset threshold and the first target refrigerated temperature interval is used as the target refrigerated temperature interval of the third area. Therefore, 1° C. to 14° C. is set as the target refrigerated temperature range of the third area.

[0050] S103, obtaining the energy-saving refrigeration temperature of each area when it is in the energy-saving mode.

[0051] In one example, after determining the target refrigerated temperature range for each storage area, it is also necessary to obtain the corresponding stable energy-saving refrigerated temperature of each area when entering the energy-saving mode. Because the temperature in the energy-saving mode of each area will be affected by many factors such as the size of the area and the material of the partition, a fixed temperature cannot be simply preset. In order to obtain accurate energy-saving refrigerated temperatures, a temperature sensor can be installed in each storage area, and the refrigerator can be allowed to enter the energy-saving mode after running in the usual way for a period of time. In energy-saving mode, the temperature sensor monitors the temperature changes in each area in real time, and records and generates a curve of the change of the regional refrigerated temperature over time. By analyzing the change curve, it can be observed that the regional refrigerated temperature will first drop and then stabilize. At this time, the temperature value after the change curve stabilizes is taken as the energy-saving refrigerated temperature of the area. By repeatedly measuring and taking the average value, the accurate energy-saving refrigerated temperature value of each area can be obtained.

[0052] Based on the above embodiment, as an optional implementation, in S103, obtaining the energy-saving refrigeration temperature of each area when it is in the energy-saving mode specifically includes:

[0053] Measure and record the refrigeration temperature change curve of each area after entering the energy-saving mode; determine the temperature value after the refrigeration temperature change curve tends to be stable based on the refrigeration temperature change curve; and use the temperature value after each refrigeration temperature change curve tends to be stable as the energy-saving refrigeration temperature of each area.

[0054] In one example, the refrigeration temperature change curve of each area after entering the energy-saving mode is measured and recorded. A temperature sensor is installed in each area of ​​the refrigerated cabinet, and the temperature change is continuously monitored and recorded by a data recording device. For example, the refrigerated cabinet is divided into three areas A, B and C, which store different types of items. After entering the energy-saving mode, the temperature of each area is recorded at regular intervals (such as every minute) by the temperature sensor, and a corresponding temperature change curve is generated.

[0055] According to the refrigeration temperature change curve, determine the temperature value after the refrigeration temperature change tends to stabilize. Specifically, analyze the temperature change curve of each area and observe the trend of temperature change. When the fluctuation amplitude of the temperature change curve gradually decreases and tends to a stable value, record the stable value. For example, the temperature change curve of area A shows that the temperature gradually decreases from 5°C to 3°C in the first 30 minutes after entering the energy-saving mode, and fluctuates around 3°C before stabilizing and finally stabilizing at 3°C; the temperature change curve of area B shows that it decreases from 6°C to 4°C in the first 20 minutes and stabilizes at 4°C; the temperature change curve of area C shows that it decreases from 7°C to 5°C in the first 25 minutes and stabilizes at 5°C.

[0056] The temperature value after each refrigeration temperature changes tends to be stable is used as the energy-saving refrigeration temperature of each area. Based on the above analysis, the energy-saving refrigeration temperature of area A is determined to be 3°C, the energy-saving refrigeration temperature of area B is 4°C, and the energy-saving refrigeration temperature of area C is 5°C. These temperature values ​​are set as the target energy-saving refrigeration temperature of each area, and the control system of the refrigerator is adjusted to keep each area within these temperature ranges in energy-saving mode.

[0057] S104, adjusting the refrigeration temperature of the first area to an energy-saving refrigeration temperature, and the energy-saving refrigeration temperature of the first area is within a target refrigeration temperature range.

[0058] In one example, the refrigeration temperature of the first area is adjusted to the energy-saving refrigeration temperature to ensure that the energy-saving refrigeration temperature of the first area is within the target refrigeration temperature range. Under the premise of maintaining the quality of the goods, the energy consumption is optimized by adjusting the refrigeration temperature to achieve energy-saving effect.

[0059] Specifically, the energy-saving refrigeration temperature of the first area obtained in step S103 has been calculated to be within the acceptable range of the product quality and also belongs to the target refrigeration temperature range determined in step S102. The temperature of the first area is monitored and adjusted in real time by a temperature sensor and a control device.

[0060] Gradually adjust the temperature of the first area from the current temperature to the energy-saving refrigeration temperature. For example, if the current temperature of the first area is 2°C and the energy-saving refrigeration temperature is 4°C, the system will control the working state of the refrigeration device and the air cooler to slowly increase the temperature to 4°C. This process needs to be carried out smoothly to avoid excessive temperature fluctuations that affect the quality of the goods.

[0061] During the temperature adjustment process, the temperature change and the state of the items in the first area are continuously monitored. Once it is detected that the temperature of the first area reaches the set energy-saving refrigeration temperature and the items are in good condition, the temperature is maintained and the energy-saving mode is entered. In the energy-saving mode, the operating frequency of the refrigeration device is reduced, thereby reducing energy consumption.

[0062] S105 adjusts the refrigeration temperature of the second area to the target refrigeration temperature, the energy-saving refrigeration temperature of the second area is not in the refrigeration temperature range, and the target refrigeration temperature is the temperature with the lowest energy consumption in the target refrigeration temperature range.

[0063] In one example, the target refrigerated temperature interval of the second area determined in step S102 is the optimal storage temperature range determined based on the number and type of items. For example, the target refrigerated temperature interval of the second area is 2°C to 4°C.

[0064] Since the energy-saving refrigeration temperature of the second area is not within the above target refrigeration temperature range, the temperature with the lowest energy consumption needs to be selected as the target refrigeration temperature according to the target refrigeration temperature range. The system's built-in energy consumption model and database will provide energy consumption data for each temperature point. By analyzing these data, it can be determined which temperature point in the target refrigeration temperature range has the lowest energy consumption. For example, through analysis, it was found that in the range of 2°C to 4°C, the energy consumption at 3°C ​​is the lowest.

[0065] Set 3℃ as the target refrigeration temperature for the second area. Next, use the temperature sensor and control equipment to gradually adjust the temperature of the second area to 3℃. This process needs to be carried out smoothly to avoid excessive temperature fluctuations that affect the quality of the goods. The system will issue instructions to control the working status of the refrigeration device and the air cooler to gradually reduce or increase the temperature to 3℃.

[0066] During the temperature adjustment process, the temperature change and the status of the items in the second area are continuously monitored. Once the temperature in the second area is detected to reach 3°C and the items are in normal condition, the system will maintain this temperature. This adjustment method not only ensures that the items are within the optimal storage temperature range, but also achieves energy consumption optimization.

[0067] Based on the above embodiment, as an optional implementation manner, after adjusting the refrigeration temperature of the second area to the target refrigeration temperature, the following steps are specifically included:

[0068] S201, obtaining an influence coefficient of the first area on the refrigeration temperature of the second area.

[0069] In one example, it is necessary to monitor the temperature changes of the first area and the second area in real time by arranging temperature sensors in the two areas. Through a period of data collection, the impact of the temperature change of the first area on the temperature of the second area under different environmental conditions and operating conditions is recorded. For example, when the temperature of the first area rises by 1°C, the change in the temperature of the second area is recorded.

[0070] After data collection is completed, the data is analyzed to calculate the influence coefficient of the first area on the refrigerated temperature of the second area. The influence coefficient can be expressed as a value that reflects the proportional relationship between the temperature change of the first area and the temperature change of the second area. For example, if the temperature of the first area rises by 1°C, the temperature of the second area rises by 0.2°C, then the influence coefficient is 0.2.

[0071] When calculating the influence coefficient, the system will take into account a variety of factors, including the insulation performance of the refrigerator, the air circulation path, the layout of the refrigeration equipment, etc. Through a complex algorithm model, the system can accurately calculate the influence coefficient of the first area on the temperature of the second area.

[0072] The process of obtaining the influence coefficient can be achieved through the following steps: Data collection: high-precision temperature sensors are arranged in the first area and the second area to monitor temperature changes in real time. Data analysis: record the impact of temperature changes in the first area on the temperature of the second area under different environmental conditions. Calculate the influence coefficient: calculate the influence coefficient of the first area on the second area through the algorithm model to obtain a value reflecting the proportional relationship of temperature changes.

[0073] The specific implementation steps for obtaining the influence coefficient are as follows: Install high-precision temperature sensors in the first area and the second area respectively. These sensors should be able to monitor and record temperature changes in real time. Ensure the calibration and accuracy of the temperature sensors to ensure the reliability of the data.

[0074] Set initial conditions: Set the temperature of the first and second regions to a stable initial value. For example, the first region is set to 2°C and the second region is set to 4°C. Gradually change the temperature of the first region and record the temperature response of the second region. The experiment can be performed in the following ways:

[0075] Gradually increase the temperature of the first area (for example, increase it by 1°C each time), and record the temperature change of the second area. Gradually reduce the temperature of the first area (for example, reduce it by 1°C each time), and record the temperature change of the second area. Data recording: For each temperature change step, record the corresponding temperature change data. For example, when the temperature of the first area rises to 3°C, 4°C, and 5°C, record the temperature change of the second area respectively.

[0076] Organize the temperature change data recorded during the experiment into a table to clarify the temperature change in the second area corresponding to each temperature change in the first area. Use statistical methods to analyze the data and calculate the average impact of the temperature change in the first area on the temperature change in the second area. Calculate the proportional relationship between the temperature change in the first area and the temperature change in the second area through linear regression or other appropriate mathematical models. Assume that the linear relationship obtained by linear regression analysis is ΔT2=K×ΔT1, where k is the influence coefficient, ΔT1 is the temperature change in the first area, and ΔT2 is the temperature change in the second area.

[0077] Verify the accuracy of the calculated influence coefficient through additional experiments. Adjust the temperature of the first region again and observe whether the temperature change of the second region is in line with the prediction. If the experimental results deviate from the calculated results, adjust the influence coefficient appropriately to ensure its accuracy.

[0078] S202, calculating the difference between the energy-saving refrigeration temperature of the first area and the target refrigeration temperature of the second area.

[0079] S203: When the difference is greater than a threshold, adjusting the refrigeration temperature of the first area and / or the second area according to the influence coefficient.

[0080] In one example, the temperature of the first area and the second area needs to be monitored in real time. The system uses high-precision temperature sensors arranged in the two areas to continuously collect temperature data. The temperature difference between the first area and the second area is continuously calculated and compared with a preset threshold.

[0081] When the temperature difference is greater than the preset threshold, the temperature is adjusted according to the previously calculated influence coefficient. The influence coefficient already reflects the proportional relationship between the temperature change in the first area and the temperature change in the second area. Assuming the influence coefficient is k, it means that for every 1°C change in the temperature of the first area, the temperature of the second area changes by k°C.

[0082] Temperature detection and difference calculation: Real-time monitoring of the temperature T1 of the first area and the temperature T2 of the second area. Calculate the temperature difference. Compare the temperature difference with the preset threshold. If the temperature difference is not greater than the preset threshold, the system maintains the current state and does not make adjustments. If the temperature difference is greater than the preset threshold, the next adjustment process is entered. Determine the adjustment strategy based on the influence coefficient k. For example, if the temperature of the first area is too high and causes the temperature of the second area to deviate from the set value, the temperature of the first area needs to be adjusted. Calculate the temperature change that needs to be adjusted. Assuming that the temperature change of the second area needs to be set to ΔT2, according to the influence coefficient k, the temperature change of the first area needs to be adjusted. Adjust the temperature T1 of the first area to change by ΔT1 degrees, thereby affecting the temperature T2 of the second area to change by ΔT2 degrees, until the temperature difference ΔT returns to within the threshold. Continuously monitor the temperature change to ensure that the adjusted temperature change meets expectations. If the expected effect is not achieved, continue to fine-tune the temperature of the first area or the second area until the temperature difference returns to within the threshold.

[0083] The method also includes: real-time monitoring of the actual refrigeration temperature of each area; determining whether the actual refrigeration temperature exceeds the target refrigeration temperature range of the corresponding area; if it exceeds the target refrigeration temperature range of the corresponding area, sending an alarm message to the user end.

[0084] In one example, it is determined whether the actual refrigerated temperature exceeds the target refrigerated temperature range of the corresponding area. The control system continuously receives and analyzes the temperature data of each area, and compares it with the pre-set target refrigerated temperature range. For example, the target refrigerated temperature range of area A is 2°C to 4°C, the target refrigerated temperature range of area B is 3°C to 5°C, and the target refrigerated temperature range of area C is 4°C to 6°C. The control system determines whether the actual temperature of each area is within the above range based on real-time data.

[0085] If the actual refrigerated temperature exceeds the target refrigerated temperature range of the corresponding area, an alarm message will be sent to the user end. Once the control system detects that the actual temperature of a certain area exceeds the preset target temperature range, the alarm mechanism will be triggered immediately and the alarm message will be sent to the user end through the network connection. The alarm message can include detailed information such as the over-temperature area, the current actual temperature, the target temperature range, etc. For example, if the actual temperature of area A exceeds 4°C, the control system will immediately generate an alarm message and send it to the user through a mobile phone application or SMS to inform the user that the temperature of area A is abnormal.

[0086] Based on the above method, the present application also discloses a refrigerator energy consumption adjustment device, such as Figure 2 As shown, Figure 2 It is a structural schematic diagram of a refrigerator energy consumption regulating device provided in an embodiment of the present application.

[0088] In one example, the above-mentioned device is also used to obtain the influence coefficient of the first area on the refrigerated temperature of the second area; calculate the difference between the energy-saving refrigerated temperature of the first area and the target refrigerated temperature of the second area; when the difference is greater than a threshold, adjust the refrigerated temperature of the first area and / or the second area according to the influence coefficient.

[0089] In one example, the above-mentioned device is also used to calculate the product of the difference between the energy-saving refrigerated temperature of the first area and the target refrigerated temperature of the second area and the influence coefficient to obtain a temperature adjustment value; if the temperature adjustment value is greater than zero, the refrigerated temperature of the first area is increased by the temperature adjustment value, and / or the refrigerated temperature of the second area is decreased by the temperature adjustment value; if the temperature adjustment value is less than zero, the refrigerated temperature of the first area is decreased by the absolute value of the temperature adjustment value, and / or the refrigerated temperature of the second area is increased by the absolute value of the temperature adjustment value; until the difference between the refrigerated temperature of the first area and the refrigerated temperature of the second area is no greater than the threshold value.

[0090] In one example, the determination module is also used to sort each item type from large to small according to the number of items in each item type to obtain a target sequence; obtain the standard refrigerated temperature ranges corresponding to multiple item types before a preset position in the target sequence, and use the intersection range between the standard refrigerated temperature ranges corresponding to the multiple item types as the target refrigerated temperature range for each area.

[0091] In one example, the determination module is also used to, if there is no intersection between the standard refrigerated temperature intervals corresponding to multiple item types before a preset position in the third area, use the standard refrigerated temperature interval corresponding to the first item type at the first position in the target sequence as the first target refrigerated temperature interval; sequentially obtain the standard refrigerated temperature intervals corresponding to multiple item types after the first position in the target sequence; determine whether the difference between the boundary value of the first target refrigerated temperature interval and the boundary value of the standard refrigerated temperature intervals corresponding to multiple item types is less than a preset threshold; if it is not less than the preset threshold, eliminate the standard refrigerated temperature intervals corresponding to items that are not less than the preset threshold; if it is less than the preset threshold, use the union of the first target refrigerated temperature interval and the standard refrigerated temperature intervals corresponding to items that are less than the preset threshold as the target refrigerated temperature interval for the third area.

[0092] In one example, the second acquisition module is also used to measure and record the refrigeration temperature change curve of each area after entering the energy-saving mode; based on the refrigeration temperature change curve, determine the temperature value after the refrigeration temperature change curve tends to be stable; and use the temperature value after each refrigeration temperature change curve tends to be stable as the energy-saving refrigeration temperature of each area.

[0093] In one example, the above device is also used to monitor the actual refrigeration temperature of each area in real time; determine whether the actual refrigeration temperature exceeds the target refrigeration temperature range of the corresponding area; if it exceeds the target refrigeration temperature range of the corresponding area, send an alarm message to the user end.
