In the biomedical field, the storage conditions of thermosensitive products such as drugs and vaccines need to strictly comply with temperature and humidity control specifications. Once deviating from the specified range, it may lead to a decline in product quality or even failure, bringing potential risks to patients. The cold chain logistics industry faces challenges such as frequent temperature fluctuations and complex and changeable environments during transportation and warehousing, and requires storage equipment to maintain stable temperature and humidity under different environmental conditions to ensure the quality and safety of goods.

[0003] To meet the multi-scenario storage requirements, a box body storage temperature and humidity control system based on single-chip microcomputer control has emerged in related technologies. This system takes the single-chip microcomputer as the core, collects the temperature and humidity data inside the box through temperature and humidity sensors, and controls the working states of refrigeration, heating, humidification or dehumidification equipment according to preset thresholds. For example, when it is detected that the temperature inside the box is lower than the set value, the system will start the heating equipment; when the temperature is higher than the set value, the refrigeration equipment will be started. Thus, it can be seen that this system can achieve basic temperature and humidity control to a certain extent.

[0036] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The attached drawings are only for reference and explanation purposes and are not used to limit the embodiments of the present disclosure.

It should be understood that the data used in this way can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0038] Unless otherwise specified, the term "plurality" means two or more.

[0039] In the embodiments of the present disclosure, the character " / " means that the objects before and after are an "or" relationship. For example, A / B means: A or B.

[0040] The term "and / or" is a description of the association relationship of an object and indicates that three relationships can exist. For example, A and / or B means: A or B, or, the three relationships of A and B.

[0041] The term "corresponding" can refer to an association relationship or a binding relationship. A corresponding to B means that there is an association relationship or a binding relationship between A and B.

[0042] Figure 1 is a schematic structural connection diagram of a refrigerated storage box system provided by the embodiments of the present disclosure; specifically, the embodiments of the present disclosure provide a refrigerated storage box including a compressor 1, a first solenoid valve 2, an exhaust connection pipe 3, a condenser 4, a filter 5, a second solenoid valve 6, a second capillary tube 7, a finned evaporator 8, a gas-liquid separator 9, a first capillary tube 10, and a smooth tube evaporator 11. The specific connection relationship is as Figure 1As shown. Among them, the compressor 1 is placed in the compressor compartment at the rear lower part of the refrigerated storage box, and its main function is to provide cold capacity to reduce the temperature of the space in the refrigerated storage box or dehumidify the space in the box. The exhaust pipe 3 is used to heat the condensed water discharged from the box to achieve automatic defrosting and evaporation, thereby keeping the environment in the box dry and clean. The condenser 4 is responsible for heat exchange with the environment, transferring the heat of the refrigerant to the environment, and ensuring the continuous operation of the refrigeration system. The first capillary 10 and the second capillary 7 are used as refrigerant throttling devices for the light tube evaporator 11 and the fin evaporator 8 respectively, and the refrigeration requirements of different evaporators are achieved by accurately controlling the flow rate of the refrigerant. The fin evaporator 8 is mainly used for auxiliary refrigeration, and the surface of the light tube evaporator 11 is attached with a cold storage module, and the cold storage module is built with cold storage materials, so as to effectively control the temperature in the box and improve the insulation capacity. The air duct riser not shown in the figure is arranged in front of the fin evaporator to form an air duct to ensure the smooth circulation of the air in the box. The evaporating fan is an adjustable speed fan that drives the air in the refrigerated storage box to circulate back and forth through the finned evaporator 8 for cooling, thereby reducing the air temperature and humidity in the refrigerated storage box. The condensing fan is responsible for forcing the heat in the condenser to be convectively transferred to the environment to ensure the heat dissipation effect of the condenser. The first solenoid valve 2 and the second solenoid valve 6 change the refrigerant flow path according to different mode settings to achieve function switching. In this way, through the coordinated work of the components, an efficient and stable refrigerated storage function can be achieved, providing reliable protection for the user's refrigeration needs.

[0043] Figure 2 is a schematic diagram of a method for controlling a refrigerated storage box provided by an embodiment of the present disclosure; Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerated storage box, comprising:

[0044] S21, the refrigerated storage box obtains target storage conditions of the items stored in the refrigerated storage box, where the target storage conditions include a temperature storage range and a humidity storage range.

[0045] S22, the refrigerated storage box determines a target operation mode of the refrigerated storage box according to the target storage condition.

[0046] S23, the refrigerated storage box controls the refrigerated storage box to execute the target operation mode.

[0047] Among them, the target operating modes include shade mode, refrigeration mode, refrigeration temperature and humidity control mode, refrigeration temperature control and insulation mode, and freezing temperature control and insulation mode.

[0048] In this solution, the refrigerated storage box can obtain the target storage conditions of the items stored in it in various ways. In one example, the refrigerated storage box can be equipped with a high-definition camera and an image recognition system inside. When an item is placed in it, the refrigerated storage box can automatically capture an image of the item and analyze information such as the type, brand, and even batch of the item through an image recognition algorithm. Based on these recognition results, the refrigerated storage box can quickly match the target storage conditions required for the item from a pre-set database, such as the temperature storage range and humidity storage range. In this way, it is not only fast and accurate but also can effectively reduce the manual operation burden of the user. In another example, for some special or unknown items, the user can manually input the name, type, and required target storage conditions of the item through the touch screen on the refrigerated storage box or the application on the connected mobile device. Although this method requires the user to have certain operation knowledge, it also provides great flexibility, allowing the user to set the storage conditions according to their own needs and experience. In an optimized solution, the two-dimensional code or barcode on the item packaging can be scanned through the scanning device on the refrigerated storage box or the mobile phone application to automatically analyze the target storage conditions of the item. This method is both convenient and fast, especially suitable for items that have been standardized and informatized.

[0049] Further, the refrigerated storage box can determine the target operation mode of the refrigerated storage box in combination with the target storage conditions. In one example, the refrigerated storage box can use an intelligent algorithm to optimize the selection of the target operation mode. Here, the algorithm selected by the refrigerated storage box comprehensively considers the storage requirements of the items, the current state of the equipment, and external environmental factors, and through complex calculations and analyses, obtains the optimal operation mode. Here, the current state of the equipment includes but is not limited to the mode state, energy consumption state, etc., and the external environmental factors include room temperature factors, humidity factors, etc. In another way, the refrigerated storage box determines the target operation mode of the refrigerated storage box according to the target storage conditions, including: when the target storage conditions include a temperature storage range of a first temperature range and a humidity storage range of a preset humidity range, the refrigerated storage box determines that the target operation mode of the refrigerated storage box is the shady mode. When the target storage conditions include a temperature storage range of a second temperature range, the refrigerated storage box determines that the target operation mode of the refrigerated storage box is the refrigerated mode. When the target storage conditions include a temperature storage range of a second temperature range and a humidity storage range of a preset humidity range, the refrigerated storage box determines that the target operation mode of the refrigerated storage box is the refrigerated temperature and humidity control mode. When the target storage conditions include a temperature storage range of a second temperature range and the items stored in the refrigerated storage box have a heat preservation requirement to maintain their activity stability, the refrigerated storage box determines that the target operation mode of the refrigerated storage box is the refrigerated temperature control and heat preservation mode. When the target storage conditions include a temperature storage range of a third temperature range, the refrigerated storage box determines that the target operation mode of the refrigerated storage box is the frozen temperature control and heat preservation mode. Among them, the minimum value of the first temperature range is higher than the maximum value of the second temperature range, and the maximum value of the third temperature range is lower than the minimum value of the second temperature range.

[0050] Further, the refrigerated storage box controls the refrigerated storage box to execute the target operation mode.

[0051] By using the method for controlling a refrigerated storage box provided by the embodiments of the present disclosure, by obtaining the target storage conditions of the items stored in the refrigerated storage box and accurately matching and determining various target operation modes of the refrigerated storage box accordingly, the refined and intelligent control of the refrigerated storage box is realized. With this solution, the operation mode can be flexibly switched according to the storage requirements of different items, effectively meeting the needs of multi-scenario mixed storage. This flexible control method significantly improves the versatility and environmental adaptability of the refrigerated storage box, ensuring that an efficient and reliable storage solution can be provided for users in various complex scenarios.

[0052] Optionally, in S22, the refrigerated storage box determines the target operation mode of the refrigerated storage box according to the target storage conditions, including:

[0053] When the target storage conditions include a temperature storage range of a first temperature range and a humidity storage range of a preset humidity range, the refrigerated storage box determines that the target operating mode of the refrigerated storage box is the shady mode.

[0054] When the target storage conditions include a temperature storage range of a second temperature range, the refrigerated storage box determines that the target operating mode of the refrigerated storage box is the refrigerated mode.

[0055] When the target storage conditions include a temperature storage range of a second temperature range and a humidity storage range of a preset humidity range, the refrigerated storage box determines that the target operating mode of the refrigerated storage box is the refrigerated temperature and humidity control mode.

[0056] When the target storage conditions include a temperature storage range of a second temperature range and the items stored in the refrigerated storage box have a heat preservation requirement to maintain their activity stability, the refrigerated storage box determines that the target operating mode of the refrigerated storage box is the refrigerated temperature control and heat preservation mode.

[0057] When the target storage conditions include a temperature storage range of a third temperature range, the refrigerated storage box determines that the target operating mode of the refrigerated storage box is the frozen temperature control and heat preservation mode.

[0058] In this solution, the minimum value of the first temperature range is higher than the maximum value of the second temperature range, and the maximum value of the third temperature range is lower than the minimum value of the second temperature range. As an example, the first temperature range is 8°C to 20°C, the second temperature range is 2°C to 8°C, the third temperature range is -10°C to -30°C, and the preset humidity range is 35% to 75%. Thus, when the target storage conditions include a temperature storage range of 8°C to 20°C and a humidity storage range of 35% to 75%, the refrigerated storage box determines that the target operating mode of the refrigerated storage box is the shady mode. When the target storage conditions include a temperature storage range of 2°C to 8°C, the target operating mode of the refrigerated storage box is determined to be the refrigerated mode. When the target storage conditions include a temperature storage range of 2°C to 8°C and a humidity storage range of 35% to 75%, the target operating mode of the refrigerated storage box is determined to be the refrigerated temperature and humidity control mode. When the target storage conditions include a temperature storage range of 2°C to 8°C and the items stored in the refrigerated storage box have a heat preservation requirement to maintain their activity stability, the target operating mode of the refrigerated storage box is determined to be the refrigerated temperature control and heat preservation mode. When the target storage conditions include a temperature storage range of -10°C to -30°C, the target operating mode of the refrigerated storage box is determined to be the frozen temperature control and heat preservation mode.

[0059] With this solution, by accurately matching the operating mode of the refrigerated storage box according to the target storage conditions, intelligent management of different food ingredients and environmental requirements is achieved. Specifically, the refrigerated storage box can flexibly switch to the shaded mode, refrigerated mode, refrigerated temperature and humidity control mode, refrigerated temperature and heat preservation mode, or frozen temperature and heat preservation mode according to the temperature and humidity ranges, as well as the special requirements of the food ingredients. In this way, not only the adaptability and preservation effect of the refrigerated storage box are improved, but also the energy consumption management is optimized, and the user experience is enhanced.

[0060] Figure 3-1 It is a refrigerant flow diagram of the refrigerated storage box operating in the shaded mode in an embodiment of the present disclosure; combined with Figure 3-1 As shown, optionally, the refrigerated storage box includes a first circuit, and the first circuit is a pipeline formed by flowing into the inlet of the compressor 1 after passing through the outlet of the compressor 1, the first solenoid valve 2, the exhaust connection pipe 3, the condenser 4, the filter 5, the second solenoid valve 6, the second capillary tube 7, the fin evaporator 8, and the gas-liquid separator 9. Specifically, in the illustrated first circuit, after the refrigerant is compressed in the compressor 1, it enters the exhaust connection pipe 3 through the first solenoid valve 2, and then flows to the condenser 4 for heat exchange. After that, the refrigerant flows through the filter 5 to remove impurities. Then, the refrigerant passes through the second solenoid valve 6 and the second capillary tube 7, enters the fin evaporator 8 for evaporation and heat absorption, and then the refrigerant flows into the gas-liquid separator 9 to separate the gaseous and liquid refrigerants. Finally, the refrigerant returns to the inlet of the compressor 1 to complete the cycle of the first circuit.

[0061] Figure 3-2 It is another method schematic diagram for controlling a refrigerated storage box provided by an embodiment of the present disclosure; combined with Figure 3-2 As shown, optionally, the target operating mode is the shaded mode, S23, and the refrigerated storage box controls the refrigerated storage box to execute the target operating mode, including:

[0062] S311, when controlling the compressor to operate at a preset speed, the refrigerated storage box controls the first solenoid valve and the second solenoid valve to switch to the first circuit.

[0063] S312, the refrigerated storage box controls the compressor to adjust the speed according to the first strategy.

[0064] S313, the refrigerated storage box controls the internal fan to perform delayed start and stop control according to the start and stop state of the compressor after the speed is adjusted.

[0065] In this solution, after the refrigerated storage box is powered on, the refrigerated storage box can control the first solenoid valve and the second solenoid valve to switch to the first circuit when the compressor is controlled to run at a preset speed. The preset speed can be the maximum speed of the compressor when it is running. The first solenoid valve and the second solenoid valve are both three-way valves. The first circuit includes a pipeline formed by flowing into the compressor inlet through the compressor outlet, the first solenoid valve, the exhaust pipe, the condenser, the filter, the second solenoid valve, the second capillary tube, the fin evaporator, and the gas-liquid separator. In this way, when the refrigerated storage box is powered on, the compressor is controlled to run at a preset maximum speed, and the first solenoid valve and the second solenoid valve are operated to switch to the first circuit to ensure switching to shade operation. In this mode, the refrigerant flows out from the outlet of the compressor, passes through the first solenoid valve, the exhaust pipe, the condenser and the filter in sequence, and then enters the fin evaporator through the second solenoid valve and the second capillary tube. After separation in the gas-liquid separator, it finally flows back to the compressor inlet to form a closed cycle. This flow switching ensures efficient flow of refrigerant in the system and optimizes the cooling effect of the refrigerated storage box. At the same time, due to the precise control of the solenoid valve, the appropriate temperature and humidity can be maintained in the shade mode, effectively extending the shelf life of the food and maintaining its freshness.

[0066] Furthermore, after the flow path is switched, the refrigerated storage box can control the compressor to adjust the speed according to the first strategy. Specifically, the refrigerated storage box determines the first strategy in the following manner:

[0067] Refrigerated Storage Box Acquires the internal temperature of the refrigerated storage box.

[0068] When the temperature inside the refrigerated storage box is higher than the second threshold and lower than the first threshold, the refrigerated storage box determines a first strategy to adjust the compressor speed according to the current ambient temperature and the low-gear tachometer.

[0069] When the temperature inside the refrigerated storage box is lower than a second threshold, the refrigerated storage box determines that the first strategy is to control the compressor to stop.

[0070] Among them, the first threshold value is the sum of the temperature setting value and the calibration value in the current mode. The second threshold value is the difference between the temperature setting value and the fluctuation value in the current mode of the refrigerated storage box. As an example, if the current mode is refrigeration mode or refrigerated temperature and humidity control mode or refrigerated temperature control and insulation mode, the temperature setting value in the box in the current mode is 5°C. If the current mode is shade mode, the temperature setting value in the box in the current mode is 15°C. If the current mode is freezing temperature control and insulation mode, the temperature setting value in the box in the current mode is -20°C. The calibration value and the fluctuation value can be set in advance. Generally, the calibration value>fluctuation value. For example, the calibration value is 3°C, and the fluctuation value ranges from 0.5°C to 1°C.

[0071] Optionally, the low - gear tachometer is as shown in the following table:

[0072] Ambient temperature Target speed of the compressor Ambient temperature ≤ 16°C 1300 r / min 16°C < Ambient temperature ≤ 25°C 1600 r / min 25°C < Ambient temperature ≤ 38°C 1800 r / min 38°C < Ambient temperature 2100 r / min

[0073] In this way, when the temperature inside the refrigerated storage box is higher than the second threshold and lower than the first threshold, the refrigerated storage box can adjust the compressor speed according to the current ambient temperature and the low - gear tachometer. For example, if the detected ambient temperature is 16°C, the target speed of the compressor can be determined to be 1300 r / min. In this way, the first strategy can be determined to adjust the compressor speed to 1300 r / min.

[0074] Optionally, the method further includes: when it is detected that the temperature inside the refrigerated storage box is higher than the third threshold, the refrigerated storage box restarts the compressor again and adjusts the compressor speed again according to the current ambient temperature and the low - gear tachometer. Here, the third threshold is the sum of the temperature set value inside the box and the fluctuation value in the current mode.

[0075] With this solution, when the temperature inside the box is between the second threshold and the first threshold, the refrigerated storage box will adjust the compressor speed according to the ambient temperature and the preset low - gear tachometer to reduce energy consumption when operating in the shaded mode. When the temperature inside the box is lower than the second threshold, the compressor will stop to further save energy. When the temperature inside the box is higher than the third threshold, the compressor will restart and adjust the speed again. This dynamic adjustment strategy not only optimizes the temperature control of the refrigerated storage box, but also significantly improves energy efficiency, extends the service life of the compressor, and ensures the freshness and quality of the ingredients when the refrigerated storage box is operating in the shaded mode.

[0076] Optionally, the refrigerated storage box controls the internal fan to perform delayed start - stop control according to the start - stop state of the compressor after speed adjustment.

[0077] In this solution, the start and stop of the internal fan are no longer synchronized with the compressor, but are adjusted according to the set first delay time F1 and second delay time F2. Specifically, when the compressor starts, the internal fan will start after a delay of F1 time, which can effectively avoid the high load at the initial stage of the compressor start and reduce energy consumption. When the compressor stops, the internal fan will be turned off after a delay of F2 time to ensure that the temperature and humidity inside the refrigerated storage box are fully adjusted. In addition, the values of the first delay time F1 and the second delay time F2 can be intelligently adjusted according to the ambient temperature. The higher the ambient temperature, the smaller the values of the first delay time F1 and the second delay time F2, to adapt to the longer startup time and better dehumidification effect in high - temperature environments. This delayed start - stop control method not only improves the energy efficiency of the refrigerated storage box, but also helps to maintain the stability of the temperature inside the box, thus enhancing the refrigeration effect.

[0078] Optionally, in the shade mode, the defrosting process of the refrigerated storage box can be performed by naturally stopping the machine for defrosting. With this solution, the power consumption and temperature rise caused by the defrosting heater in the conventional refrigerator can be reduced, thereby achieving energy saving.

[0079] Figure 3-3 is another schematic diagram of a method for controlling a refrigerated storage box provided by an embodiment of the present disclosure; Figure 3-3 As shown, optionally, the target operation mode is a refrigeration mode, S23, the refrigerated storage box controls the refrigerated storage box to execute the target operation mode, including:

[0080] S321, when the compressor is controlled to run at a preset speed, the refrigerated storage box controls the first solenoid valve and the second solenoid valve to switch to the first circuit.

[0081] S322, the refrigerated storage box controls the compressor to adjust the speed according to the second strategy, and controls the internal fan to continue to rotate to improve the uniformity of the temperature in the box.

[0082] In this solution, the refrigerant flow diagrams used in the refrigeration mode and the shade mode are the same. Figure 3-1 As shown, after the refrigerated storage box is powered on, when the compressor is controlled to run at a preset speed, the refrigerated storage box can control the first solenoid valve and the second solenoid valve to switch to the first circuit. The preset speed can be the maximum speed when the compressor is running. The first solenoid valve and the second solenoid valve are both three-way valves. The first circuit includes a pipeline formed by flowing into the compressor inlet after passing through the compressor outlet, the first solenoid valve, the exhaust pipe, the condenser, the filter, the second solenoid valve, the second capillary tube, the fin evaporator, and the gas-liquid separator.

[0083] In this way, when the refrigerated storage box is powered on, the compressor is controlled to run at a preset maximum speed, and the first solenoid valve and the second solenoid valve are operated to switch to the first circuit to ensure switching to the refrigeration mode. In this mode, the refrigerant flows out from the outlet of the compressor, passes through the first solenoid valve, the exhaust pipe, the condenser and the filter in sequence, and then enters the fin evaporator through the second solenoid valve and the second capillary tube. After separation in the gas-liquid separator, it finally flows back to the compressor inlet to form a closed loop. This flow path switching ensures the efficient flow of the refrigerant in the system and optimizes the cooling effect of the refrigerated storage box. At the same time, due to the precise control of the solenoid valve, the appropriate temperature and humidity can be maintained in the refrigeration mode, which effectively extends the shelf life of the food and maintains its freshness.

[0084] Furthermore, after the flow path of the refrigerated storage box is switched, the compressor can be controlled to adjust the speed according to the second strategy while the internal fan can be controlled to continue to rotate to improve the uniformity of the temperature in the box.

[0085] Specifically, the cold storage box determines the second strategy in the following manner:

[0086] The refrigerated storage box obtains the temperature inside the box of the refrigerated storage box.

[0087] When the temperature inside the box of the refrigerated storage box is higher than the second threshold and lower than the first threshold, the refrigerated storage box determines that the second strategy is to adjust the compressor speed according to the current ambient temperature and the high gear tachometer.

[0088] When the temperature inside the box of the refrigerated storage box is lower than the second threshold, the refrigerated storage box determines that the second strategy is to control the compressor to stop.

[0089] Wherein, the first threshold is the sum of the set value of the temperature inside the box and the calibration value in the current mode. The second threshold is the difference between the set value of the temperature inside the box and the fluctuation value in the current mode of the refrigerated storage box. As an example, if the current mode is the refrigeration mode or the refrigeration temperature and humidity control mode or the refrigeration temperature and heat preservation mode, the set value of the temperature inside the box in the current mode is 5°C. If the current mode is the shady mode, the set value of the temperature inside the box in the current mode is 15°C. If the current mode is the freezing temperature and heat preservation mode, the set value of the temperature inside the box in the current mode is -20°C. The calibration value and the fluctuation value can be preset. Generally, the calibration value > the fluctuation value. For example, the calibration value is 3°C, and the value range of the fluctuation value is 0.5°C to 1°C.

[0090] Optionally, the high gear tachometer is as shown in the following table:

[0091] Ambient temperature Target speed of the compressor Ambient temperature ≤ 16°C 2200 r / min 16°C < Ambient temperature ≤ 25°C 2800 r / min 25°C < Ambient temperature ≤ 38°C 3500 r / min 38°C < Ambient temperature 4000 r / min

[0092] In this way, when the temperature inside the box of the refrigerated storage box is higher than the second threshold and lower than the first threshold, the refrigerated storage box can adjust the compressor speed according to the current ambient temperature and the high gear tachometer. For example, if the detected ambient temperature is 16°C, the target speed of the compressor can be determined to be 2200 r / min. In this way, the second strategy can be determined to adjust the compressor speed to 2200 r / min.

[0093] Optionally, in the refrigeration mode, the defrosting process of the refrigerated storage box can adopt the method of natural shutdown defrosting. With this solution, the power consumption and temperature rise caused by the defrosting heater in a conventional refrigerator can be reduced, and energy conservation can be achieved.

[0094] Figure 4-1 It is another schematic diagram of the method for controlling a refrigerated storage box provided by an embodiment of the present disclosure; in combination with Figure 4-1 As shown, the target operating mode is the refrigeration temperature and humidity control mode, S23, and the refrigerated storage box controls the refrigerated storage box to execute the target operating mode, including:

[0095] S41, when controlling the compressor to operate at a preset speed, the refrigerated storage box controls the first solenoid valve and the second solenoid valve to switch to the first circuit.

[0096] S42, the refrigerated storage box controls the compressor to adjust its rotational speed according to the third strategy.

[0097] S43, the refrigerated storage box controls the internal blower to perform delayed start / stop control according to the start / stop state of the compressor after the rotational speed adjustment.

[0098] S44, when the surface temperature of the evaporator meets the defrosting condition, the refrigerated storage box controls the compressor to switch from the state after the rotational speed adjustment to the start state, switches the first solenoid valve to the second circuit, and controls the internal blower to stop.

[0099] In this solution, the refrigerant flow diagrams used in the temperature control stage and the humidity control stage of the refrigerated temperature and humidity control mode are the same as those of the shady mode. Specifically, after the refrigerated storage box is powered on, when controlling the compressor to operate at a preset rotational speed, the refrigerated storage box can control the first solenoid valve and the second solenoid valve to switch to the first circuit. Among them, the preset rotational speed can be the maximum rotational speed during the operation of the compressor. Both the first solenoid valve and the second solenoid valve are three-way valves. The first circuit includes the pipeline formed by flowing into the compressor inlet after passing through the compressor outlet, the first solenoid valve, the exhaust connection pipe, the condenser, the filter, the second solenoid valve, the second capillary tube, the finned evaporator, and the gas-liquid separator. In this way, when the refrigerated storage box is powered on, by controlling the compressor to operate at the preset maximum rotational speed and operating the first solenoid valve and the second solenoid valve to switch to the first circuit, it is ensured to switch to the refrigerated temperature and humidity control mode. In this mode, the refrigerant flows out from the outlet of the compressor, passes through the first solenoid valve, the exhaust connection pipe, the condenser and the filter in sequence, then enters the finned evaporator through the second solenoid valve and the second capillary tube, and after being separated in the gas-liquid separator, finally returns to the compressor inlet to form a closed cycle. This flow path switching ensures the efficient flow of the refrigerant in the system, optimizes the cooling effect of the refrigerated storage box, and at the same time, due to the precise control of the solenoid valve, it can maintain a suitable temperature and humidity in the refrigerated temperature and humidity control mode, effectively extending the fresh-keeping time of the food ingredients and maintaining their freshness.

[0100] Furthermore, after the refrigerated storage box performs the flow path switching, it can control the compressor to adjust its rotational speed according to the third strategy. Specifically, the refrigerated storage box determines the third strategy through the following methods:

[0101] The refrigerated storage box obtains the temperature inside the refrigerated storage box.

[0102] When the temperature inside the refrigerated storage box is higher than the second threshold and lower than the first threshold, the refrigerated storage box determines that the third strategy is to adjust the rotational speed of the compressor according to the current ambient temperature and the high gear rotational speed table.

[0103] When the temperature inside the refrigerated storage box is lower than the second threshold, the refrigerated storage box determines that the third strategy is to control the compressor to stop.

[0104] Among them, the first threshold is the sum of the set value and the calibration value of the temperature inside the box in the current mode. The second threshold is the difference between the set value of the temperature inside the box and the fluctuation value in the current mode of the refrigerated storage box. As an example, if the current mode is the refrigeration mode, the refrigeration temperature and humidity control mode, or the refrigeration temperature and heat preservation mode, the set value of the temperature inside the box in the current mode is 5°C. If the current mode is the shady mode, the set value of the temperature inside the box in the current mode is 15°C. If the current mode is the freezing temperature and heat preservation mode, the set value of the temperature inside the box in the current mode is -20°C. The calibration value and the fluctuation value can be preset. Generally, the calibration value > the fluctuation value. For example, the calibration value is 3°C, and the value range of the fluctuation value is from 0.5°C to 1°C.

[0105] Optionally, the high gear tachometer is as shown in the following table:

[0106] Ambient temperature Target speed of the compressor Ambient temperature ≤ 16°C 2200 r / min 16°C < Ambient temperature ≤ 25°C 2800 r / min 25°C < Ambient temperature ≤ 38°C 3500 r / min 38°C < Ambient temperature 4000 r / min

[0107] In this way, when the temperature inside the refrigerated storage box is higher than the second threshold and lower than the first threshold, the refrigerated storage box can adjust the compressor speed according to the current ambient temperature and the high gear tachometer.

[0108] Optionally, the method further includes: when it is detected that the temperature inside the refrigerated storage box is higher than the third threshold, the refrigerated storage box restarts the compressor again and adjusts the compressor speed again according to the current ambient temperature and the high gear tachometer. Here, the third threshold is the sum of the set value of the temperature inside the box and the fluctuation value in the current mode.

[0109] With this solution, when the temperature inside the box is between the second threshold and the first threshold, the refrigerated storage box will adjust the compressor speed according to the ambient temperature and the preset high gear tachometer to reduce energy consumption when operating in the refrigeration temperature and humidity control mode. When the temperature inside the box is lower than the second threshold, the compressor will stop to further save energy. And when the temperature inside the box is higher than the third threshold, the compressor will restart and adjust the speed again. This dynamic adjustment strategy not only optimizes the temperature control of the refrigerated storage box, but also significantly improves the energy efficiency, extends the service life of the compressor, and at the same time ensures the freshness and quality of the ingredients when the refrigerated storage box operates in the refrigeration temperature and humidity control mode.

[0110] Optionally, when the target operating mode is the refrigeration temperature and humidity control mode, when the compressor speed starts at a high gear, it can use the temperature on the evaporator surface lower than the dew point temperature for dehumidification.

[0111] Optionally, the refrigerated storage box controls the internal fan to perform delayed start and stop control according to the start and stop state of the compressor after the speed adjustment.

[0112] In this solution, the startup and shutdown of the internal fan are no longer synchronized with the compressor, but are adjusted according to the set first delay time F1 and second delay time F2. Specifically, after the compressor starts, the internal fan will start with a delay of F1 time, which can effectively avoid the high load at the initial stage of the compressor startup and reduce energy consumption. When the compressor stops, the internal fan will be turned off with a delay of F2 time to ensure that the temperature and humidity in the refrigerated storage box are fully adjusted. In addition, the values of the first delay time F1 and the second delay time F2 can be intelligently adjusted according to the ambient temperature. The higher the ambient temperature, the smaller the values of the first delay time F1 and the second delay time F2, to adapt to the longer startup time and better dehumidification effect in high-temperature environments. This delayed startup and shutdown control method not only improves the energy efficiency of the refrigerated storage box, but also helps to maintain the stability of the temperature inside the box, thus enhancing the refrigeration effect.

[0113] In an optimized solution, the refrigerated storage box further includes an internal humidification system. This system includes a humidification box and an auxiliary fan. When the built-in humidity sensor detects that the humidity inside the box is lower than the preset lower threshold H1, the auxiliary fan will be activated to promote the evaporation of the water in the humidification box by blowing air, thereby increasing the humidity inside the box. On the contrary, when the humidity sensor detects that the humidity inside the box exceeds the preset upper threshold H2, the auxiliary fan will stop running to prevent over-humidification. This automated humidity adjustment mechanism not only ensures a constant and suitable humidity environment inside the refrigerated storage box, but also helps to maintain the freshness and quality of the ingredients, while avoiding the inconvenience of manual adjustment.

[0114] Figure 4-2 is a refrigerant flow diagram of a refrigerated storage box running refrigeration defrosting in an embodiment of the present disclosure; combined with Figure 4-2 As shown, the refrigerated storage box includes a second circuit, and the second circuit includes a pipeline formed by flowing into the compressor 1 inlet after passing through the outlet of the compressor 1, the first solenoid valve 2, the fin evaporator 8, and the gas-liquid separator 9. Specifically, in the illustrated second circuit, after the refrigerant is compressed in the compressor 1, it flows to the first solenoid valve 2. Subsequently, the refrigerant flows through the fin evaporator 8 for heat exchange, and then flows into the gas-liquid separator 9 to separate the gaseous and liquid refrigerants. Finally, the refrigerant returns to the inlet of the compressor 1 to complete the cycle of the second circuit. This process ensures that under defrosting conditions, the refrigerant can flow along a predetermined path to achieve effective heat exchange and the normal operation of the system.

[0115] Optionally, when the surface temperature of the evaporator meets the defrosting condition, control the compressor to switch from the state after speed adjustment to the startup state, switch the first solenoid valve to the second circuit, and control the internal fan to stop running, where the second circuit includes a pipeline formed by flowing into the compressor inlet after passing through the compressor outlet, the first solenoid valve, the fin evaporator, and the gas-liquid separator.

[0116] Specifically, a defrost sensor is set on the surface of the fin evaporator. When the defrost sensor detects that the surface temperature of the evaporator is lower than the low temperature critical value for multiple consecutive startups, the compressor starts immediately. The low temperature critical value is -2°C. In this way, when the defrost sensor detects that the surface temperature of the evaporator is lower than the fourth threshold, the temperature inside the box is lowered in advance to prevent the temperature inside the box from overheating during defrosting. The fourth threshold is the difference between the set value and the floating value of the temperature inside the refrigerated storage box in the current mode. The floating value can be set in advance, for example, the floating value is 1°C. In this way, by switching the first solenoid valve to the second circuit, the exhaust heat of the compressor can be used to defrost the surface of the fin, and the internal fan stops.

[0117] Optionally, when the defrost sensor detects that the surface temperature of the evaporator is higher than the temperature collected by the temperature sensor in the box, the defrost exit operation is executed. Here, the defrost exit operation includes controlling the compressor to stop, the internal fan to keep stopping, and delaying the start of F3 time. In this scheme, the hot gas defrosting method effectively avoids ice blockage caused by the accumulation of residual frost left by the unevenness of electric defrosting, greatly reducing the failure rate.

[0118] Figure 5-1 is a refrigerant flow diagram of a refrigerated storage box in a refrigerated temperature control and insulation mode according to an embodiment of the present disclosure; Figure 5-1 As shown, optionally, the cold storage box includes a third circuit, which is a pipeline formed by flowing into the inlet of the compressor 1 after passing through the outlet of the compressor 1, the first solenoid valve 2, the exhaust pipe 3, the condenser 4, the filter 5, the second solenoid valve 6, the first capillary 10, the light tube evaporator 11, and the gas-liquid separator 9, and the surface of the light tube evaporator 11 is attached with a cold storage module. The cold storage module is built with cold storage material. Here, the cold storage module can be a first cold storage module or a second cold storage module. If the current operating mode is a refrigeration temperature control and insulation mode, the cold storage material built into the first cold storage module is paraffin. If the current operating mode is a freezing temperature control and insulation mode, the cold storage material built into the second cold storage module is water. Specifically, in the third circuit shown in the figure, after the refrigerant is compressed in the compressor 1, it passes through the first solenoid valve 2 and enters the exhaust pipe 3, then undergoes heat exchange through the condenser 4, and then flows through the filter 5 to remove impurities. Subsequently, the refrigerant passes through the second solenoid valve 6 and the first capillary tube 10 and enters the light tube evaporator 11, where it evaporates and absorbs heat. At the same time, the first cold storage module attached to the surface of the light tube evaporator assists in absorbing and releasing heat. The evaporated refrigerant gas flows into the gas-liquid separator 9, where the liquid refrigerant is separated and returned to the inlet of the compressor 1, completing the refrigerant cycle of the third circuit. This process ensures that the system can effectively exchange heat and store cold in a specific mode, optimizing the energy efficiency and temperature control of the refrigerated storage box.

[0119] Figure 5-2is another schematic diagram of a method for controlling a refrigerated storage box provided by an embodiment of the present disclosure; Figure 5-2 As shown, the target operation mode is the refrigerated temperature control and insulation mode, S23, the refrigerated storage box controls the refrigerated storage box to execute the target operation mode, including:

[0120] S511, when the compressor is controlled to operate at a preset speed, the refrigerated storage box controls the first solenoid valve and the second solenoid valve to switch to the third circuit.

[0121] S512, the refrigerated storage box controls the compressor to adjust the speed according to the fourth strategy.

[0122] In this solution, after the refrigerated storage box is powered on, the refrigerated storage box can control the first solenoid valve and the second solenoid valve to switch to the third circuit when the compressor is controlled to run at a preset speed. The preset speed can be the maximum speed when the compressor is running. The first solenoid valve and the second solenoid valve are both three-way valves. The third circuit includes a pipeline formed by the compressor outlet, the first solenoid valve, the exhaust pipe, the condenser, the filter, the second solenoid valve, the first capillary tube, the light tube evaporator, and the gas-liquid separator, and the first cold storage module is attached to the surface of the light tube evaporator. The cold storage material built into the first cold storage module is paraffin. In this solution, by controlling the compressor to run at a preset maximum speed and operating the first solenoid valve and the second solenoid valve to switch to the third circuit, it is ensured that the refrigerant flows through a specific pipeline including the light tube evaporator and the first cold storage module, wherein the paraffin attached to the surface of the light tube evaporator can absorb and release heat during the flow of the refrigerant, that is, the refrigeration capacity of the light tube evaporator is used to cool the first cold storage module, and the temperature of the first cold storage module is used to cool the items in the box. This design not only improves the temperature control accuracy of the refrigerated storage box, but also optimizes energy consumption, extends the service life of the compressor, and maintains a stable temperature inside the box through the auxiliary role of the cold storage module, thereby providing a more suitable storage environment for items that require temperature control and insulation.

[0123] Furthermore, after the flow path is switched, the refrigerated storage box can control the compressor to adjust the speed according to the fourth strategy. Specifically, the refrigerated storage box determines the fourth strategy in the following manner:

[0124] Refrigerated Storage Box Acquires the internal temperature of the refrigerated storage box.

[0125] When the temperature inside the refrigerated storage box is lower than the second threshold, the refrigerated storage box determines that the fourth strategy is to control the compressor to stop.

[0126] When it is detected that the temperature inside the refrigerated storage box is higher than the third threshold, the refrigerated storage box determines that the fourth strategy is to restart the compressor and adjust the compressor speed according to the current ambient temperature and the low-gear tachometer.

[0127] Wherein, the second threshold is the difference between the set value and the fluctuation value of the temperature inside the refrigerated storage box in the current mode. The third threshold is the sum of the set value and the fluctuation value of the temperature inside the box in the current mode. In one example, the fluctuation value can be preset. For example, the value range of the fluctuation value is from 0.5°C to 1°C.

[0128] Optionally, the low gear tachometer is as shown in the following table:

[0129] Ambient temperature Target speed of the compressor Ambient temperature ≤ 16°C 1300 r / min 16°C < Ambient temperature ≤ 25°C 1600 r / min 25°C < Ambient temperature ≤ 38°C 1800 r / min 38°C < Ambient temperature 2100 r / min

[0130] In this way, when the temperature inside the refrigerated storage box is higher than the third threshold, the refrigerated storage box can adjust the compressor speed according to the current ambient temperature and the low gear tachometer.

[0131] With this solution, in the refrigerated temperature control and heat preservation mode, the compressor operates at the preset maximum speed. Through the control of the first and second solenoid valves, the refrigerant flows to the third circuit, so that the light tube evaporator absorbs heat during the flow of the refrigerant for cooling, while the paraffin material in the first cold storage module assists in temperature control during the process of absorbing and releasing heat, providing a stable low-temperature environment for the items inside the box. In addition, the refrigerated storage box intelligently adjusts the operation strategy of the compressor according to the comparison result between the temperature inside the box and the preset threshold, thereby optimizing energy consumption and extending the life of the compressor. This intelligent temperature control not only improves the energy efficiency of the refrigerated storage box, but also ensures the stability of the temperature inside the box, providing ideal storage conditions for items that require precise temperature control.

[0132] Figure 5-3 It is another schematic diagram of a method for controlling a refrigerated storage box provided by an embodiment of the present disclosure; in combination with Figure 5-3 As shown, the target operation mode is the freezing temperature control and heat preservation mode. S23, the refrigerated storage box controls the refrigerated storage box to execute the target operation mode, including:

[0133] S521, when controlling the compressor to operate at a preset speed, the refrigerated storage box controls the first solenoid valve and the second solenoid valve to switch to the third circuit.

[0134] S522, the refrigerated storage box controls the compressor to adjust the speed according to the fifth strategy.

[0135] In this solution, the refrigerant flow diagram used in the freezing temperature control and insulation mode is the same as that used in the refrigeration temperature control and insulation mode. Specifically, after the refrigerated storage box is powered on, when the compressor is controlled to run at a preset speed, the refrigerated storage box can control the first solenoid valve and the second solenoid valve to switch to the third circuit. Among them, the preset speed can be the maximum speed when the compressor is running. The first solenoid valve and the second solenoid valve are both three-way valves. The third circuit includes a pipeline formed by flowing into the compressor inlet after passing through the compressor outlet, the first solenoid valve, the exhaust pipe, the condenser, the filter, the second solenoid valve, the first capillary tube, the light tube evaporator, and the gas-liquid separator. The second cold storage module is attached to the surface of the light tube evaporator. The cold storage material built into the second cold storage module is water. As an example, the second cold storage module can be a water box or an ice block fixed in advance to the foaming layer. This solution not only improves the temperature control accuracy of the refrigerated storage box, but also optimizes energy consumption, extends the service life of the compressor, and maintains the stability of the temperature inside the box through the auxiliary role of the cold storage module, providing a more suitable storage environment for items that require temperature control and insulation, so as to maintain efficient and energy-saving operation in both freezing temperature control and insulation mode.

[0136] Furthermore, after the flow path is switched, the refrigerated storage box can control the compressor to adjust the speed according to the fifth strategy. Specifically, the refrigerated storage box determines the fifth strategy in the following manner:

[0137] Refrigerated Storage Box Acquires the internal temperature of the refrigerated storage box.

[0138] In a case where the temperature inside the refrigerated storage box is lower than the second threshold, the refrigerated storage box determines a fifth strategy as controlling the compressor to stop.

[0139] When it is detected that the temperature inside the refrigerated storage box is higher than the third threshold, a fifth strategy is determined to restart the compressor of the refrigerated storage box and adjust the compressor speed according to the current ambient temperature and a high-speed tachometer.

[0140] The second threshold is the difference between the temperature setting value and the fluctuation value in the current mode of the refrigerated storage box. The third threshold is the sum of the temperature setting value and the fluctuation value in the current mode. In one example, the fluctuation value can be pre-set. For example, the fluctuation value ranges from 0.5°C to 1°C.

[0141] Optionally, the high-speed speed table is shown in the following table:

[0142] Ambient temperature Target speed of the compressor Ambient temperature ≤ 16°C 2200 r / min 16°C < Ambient temperature ≤ 25°C 2800 r / min 25°C < Ambient temperature ≤ 38°C 3500 r / min 38°C < Ambient temperature 4000 r / min

[0143] In this way, when it is detected that the temperature inside the refrigerated storage box is higher than the third threshold, the refrigerated storage box can adjust the speed of the compressor according to the current ambient temperature and the high-speed tachometer.

[0144] With this solution, by controlling the preset speed of the compressor and the switching of the solenoid valve, precise control of the refrigerant flow direction in the third circuit is achieved. This circuit includes a compressor, an exhaust pipe, a condenser, a filter, a capillary tube, a finned-tube evaporator, and a gas-liquid separator. The surface of the finned-tube evaporator is attached with a second cold storage module with an internal water-based cold storage material. This design not only enhances the accuracy of temperature control but also optimizes energy consumption with the heat capacity of the cold storage module, maintains the stability of the temperature inside the box, and extends the service life of the compressor. In addition, by implementing the fifth strategy, it can quickly respond when the temperature exceeds the third threshold and adjust according to the ambient temperature and the high-grade speed table to ensure efficient and energy-saving operation in the freezing temperature control and heat preservation mode, providing ideal storage conditions for items that require precise temperature control.
