Description

Technical Field

[0001] This invention relates to the field of refrigeration electrical technology, and in particular to a method for controlling the temperature of a vehicle refrigerator, a vehicle refrigerator, electronic equipment, and a storage medium. Background Technology

[0002] A dual-temperature, dual-control car refrigerator is a portable refrigeration device that can simultaneously meet freezing and refrigeration needs. It features two independent temperature control zones, allowing users to set different temperatures according to the storage requirements of different foods. This type of refrigerator typically uses compressor refrigeration technology, achieving a cooling effect of -18°C, far superior to semiconductor refrigeration technology. Dual-temperature, dual-control car refrigerators can achieve rapid cooling; some models can reach 0°C within 15 minutes.

[0003] Most existing dual-temperature, dual-control vehicle refrigerators use two capillary tubes to transport refrigerant to the evaporators of the two separate temperature compartments to achieve refrigeration (see attached). Figure 1 (As shown). When both the refrigerator and freezer compartments require refrigeration, the refrigerant enters the evaporators of the refrigerator and freezer compartments through two capillary tubes respectively, allowing both compartments to cool simultaneously. When the refrigerator compartment reaches the designated temperature or no longer requires refrigeration, the refrigerant enters only the freezer compartment evaporator through a single capillary tube for refrigeration.

[0004] The compression process is the most energy-intensive step in the refrigeration process. In a vapor compression refrigeration cycle system, the compressor compresses low-pressure, low-temperature refrigerant vapor into high-pressure hot vapor. This process consumes a significant amount of electrical energy because the compressor needs to overcome system resistance to compress the refrigerant vapor to a higher pressure. The aforementioned dual-temperature, dual-control car refrigerator, due to the need to regulate the temperature of both compartments, experiences frequent brief on / off cycles of the compressor, resulting in high energy consumption. This not only increases user costs but also fails to meet increasingly stringent energy efficiency standards and environmental requirements. Furthermore, high energy consumption limits the operating time of the car refrigerator, especially when the vehicle's power supply is limited. Summary of the Invention

[0005] The purpose of this invention is to provide a method for controlling the temperature of a vehicle-mounted refrigerator, a vehicle-mounted refrigerator, an electronic device, and a storage medium, which have the advantages of reducing energy consumption, improving refrigeration efficiency, and increasing flexibility of use.

[0006] In a first aspect, the present invention provides a method for controlling the temperature of a vehicle-mounted refrigerator, wherein the vehicle-mounted refrigerator includes a first compartment and a second compartment. A first evaporator for transporting refrigerant is arranged around the first compartment, and the input end of the first evaporator is connected to a first capillary tube. A second evaporator for transporting refrigerant is arranged around the second compartment, and the input end of the second evaporator is simultaneously connected to the output end of the first evaporator and the second capillary tube via a connecting tee. The method for controlling the temperature of the vehicle-mounted refrigerator includes the following steps:

[0007] Obtain the real-time temperatures of the first greenhouse and the second greenhouse;

[0008] Calculate the first difference between the real-time temperature of the first greenhouse and the target temperature of the first greenhouse;

[0009] Calculate the second difference between the real-time temperature of the second greenhouse and the target temperature of the second greenhouse;

[0010] When both the first difference and the second difference rise to positive values, the second capillary tube is controlled to transport refrigerant to the second evaporator to cool the second greenhouse separately; when the second difference drops from a positive value to a negative value, the first capillary tube is controlled to transport refrigerant to the first evaporator to cool the first greenhouse and insulate the second greenhouse.

[0011] The vehicle-mounted refrigerator temperature control method provided by this invention acquires the real-time temperatures of two greenhouses and calculates the difference between these temperatures and the target temperature. When both the first and second differences rise to positive values, the real-time temperatures of both the first and second greenhouses are higher than the target temperature. Cooling is prioritized for the second greenhouse, which has a lower temperature requirement. Once the real-time temperature of the second greenhouse reaches the target temperature, cooling is then applied to the first greenhouse. Simultaneously, the residual heat from the first evaporator is used to maintain the temperature of the second greenhouse. Because the target temperature of the second greenhouse is lower, its cooling frequency is typically higher than that of the first greenhouse. By flexibly controlling the refrigerant flow between the first and second greenhouses, combined with real-time temperature monitoring and difference calculation, the refrigerant flow direction can be intelligently controlled, achieving coordinated cooling of both greenhouses. This helps reduce the cooling frequency of the second greenhouse, thereby reducing the number of compressor start-stop cycles and lowering energy consumption.

[0012] Furthermore, the vehicle-mounted refrigerator temperature control method further includes the following steps:

[0013] Obtain the ambient temperature of the vehicle refrigerator;

[0014] When the real-time temperature of the first greenhouse and the real-time temperature of the second greenhouse are both ambient temperatures, the first capillary tube is controlled to transport refrigerant to the first evaporator to cool both the first greenhouse and the second greenhouse simultaneously; when the first difference decreases to a negative value, the second capillary tube is controlled to transport refrigerant to the second evaporator to cool the second greenhouse alone.

[0015] By adopting the above technical solution, the refrigeration strategy can be flexibly adjusted according to the actual needs of different greenhouses, which not only ensures the refrigeration effect but also improves energy utilization efficiency.

[0016] Furthermore, a partition is detachably provided between the first greenhouse and the second greenhouse. The partition can be inserted into or removed from the vehicle-mounted refrigerator to separate or connect the first greenhouse and the second greenhouse. The temperature control method of the vehicle-mounted refrigerator further includes the following steps:

[0017] Obtain the insertion information of the partition plate;

[0018] The operating mode of the vehicle refrigerator is adjusted based on the inserted information. The operating mode includes a dual-temperature cooling mode and a single-temperature cooling mode.

[0019] By adopting the above technical solution, the vehicle refrigerator temperature control method of this application can effectively solve the problem of insufficient flexibility in the use of traditional vehicle refrigerators. It not only meets the diverse needs of users in different scenarios, but also improves energy efficiency through intelligent temperature control. Compared with traditional vehicle refrigerators with fixed partitions, the method of this application has significant advantages in both space utilization and temperature control. For example, when users need to store large food items, they can remove the middle partition to obtain more storage space; and when they need to store different types of food simultaneously, they can quickly switch to a dual-temperature mode to achieve precise temperature control. This flexibility not only improves the user experience, but also optimizes energy use according to actual needs, reducing unnecessary energy waste.

[0020] Further, the insertion information indicates either the separation status information of the partition being inserted into the vehicle refrigerator to separate the first and second compartments, or the connection status information of the partition being removed from the vehicle refrigerator to connect the first and second compartments; adjusting the operating mode of the vehicle refrigerator based on the insertion information includes the following steps:

[0021] When the inserted information is separation state information, the vehicle refrigerator is controlled to enter the dual-temperature cooling mode. During the operation of the dual-temperature cooling mode, the first target temperature of the first greenhouse is greater than the second target temperature of the second greenhouse.

[0022] When the inserted information is connectivity information, the vehicle refrigerator is controlled to enter the single-temperature cooling mode; during the operation of the single-temperature cooling mode, the first capillary tube is controlled to transport refrigerant to the first evaporator so as to cool the first greenhouse and the second greenhouse at the same time, and the target temperature of the first greenhouse and the second greenhouse are both the third target temperature.

[0023] By employing the above technical solution and acquiring the insertion information of the partition, the operating mode of the vehicle refrigerator can be flexibly adjusted. This method allows switching between dual-temperature cooling and single-temperature cooling modes according to the user's actual needs, improving the flexibility and practicality of the vehicle refrigerator.

[0024] Furthermore, operating the single-temperature cooling mode includes the following steps:

[0025] Calculate the third difference between the real-time temperature of the first greenhouse and the third target temperature;

[0026] Calculate the fourth difference between the real-time temperature of the second greenhouse and the third target temperature;

[0027] When the third and fourth differences are negative, the first and second capillary tubes are controlled to stop transporting refrigerant.

[0028] By adopting the above technical solution and acquiring the temperatures of the two greenhouses, the temperature distribution of the entire space can be better reflected, avoiding situations where the temperature in certain areas is too low or too high. Simultaneously, by promptly stopping the transport of refrigerant, energy can be effectively saved, improving the energy efficiency of the vehicle-mounted refrigerator.

[0029] Secondly, this application also provides a vehicle-mounted refrigerator, including a first greenhouse and a second greenhouse. The first greenhouse is surrounded by a first evaporator for transporting refrigerant, and the input end of the first evaporator is connected to a first capillary tube. The second greenhouse is surrounded by a second evaporator for transporting refrigerant, and the input end of the second evaporator is connected to both the output end of the first evaporator and the second capillary tube via a connecting tee. The vehicle-mounted refrigerator further includes:

[0030] A temperature acquisition module is used to acquire the real-time temperatures of the first greenhouse and the second greenhouse;

[0031] The first calculation module is used to calculate the first difference between the real-time temperature of the first greenhouse and the target temperature of the first greenhouse;

[0032] The second calculation module is used to calculate the second difference between the real-time temperature of the second greenhouse and the target temperature of the second greenhouse;

[0033] The refrigeration control module is used to control the second capillary tube to transport refrigerant to the second evaporator when both the first difference and the second difference rise to positive values, so as to refrigerate the second greenhouse alone; and to control the first capillary tube to transport refrigerant to the first evaporator when the second difference drops from a positive value to a negative value, so as to refrigerate the first greenhouse and insulate the second greenhouse.

[0034] Furthermore, it also includes a partition plate, which is detachably disposed between the first greenhouse and the second greenhouse, and the partition plate can separate or connect the first greenhouse and the second greenhouse.

[0035] Furthermore, a magnetic switch is provided between the first greenhouse and the second greenhouse. When the partition is located between the first greenhouse and the second greenhouse, the magnetic switch adjusts the vehicle refrigerator from single-temperature cooling mode to dual-temperature cooling module.

[0036] By employing the above technical solution and installing a magnetic switch between the first and second greenhouses, the automatic switching of the vehicle refrigerator's operating mode is achieved. When the middle partition is inserted between the first and second greenhouses, the magnetic switch senses the presence of the partition, thereby automatically switching the vehicle refrigerator's operating mode from single-temperature cooling mode to dual-temperature cooling mode. This design not only simplifies user operation but also improves the intelligence level of the vehicle refrigerator.

[0037] Thirdly, this application provides an electronic device including a processor and a memory, the memory storing a computer program that, when executed by the processor, performs the steps of the method provided in the first aspect above.

[0038] Fourthly, this application provides a storage medium having a computer program stored thereon, which, when executed by a processor, performs the steps of the method provided in the first aspect above.

[0039] As can be seen from the above, the vehicle refrigerator temperature control method provided by this invention obtains the real-time temperatures of the two greenhouses and calculates the difference between them and the target temperature. When both the first and second differences rise to positive values, the real-time temperatures of the first and second greenhouses are higher than the target temperature. Cooling is prioritized for the second greenhouse, which has a lower temperature requirement. Once the real-time temperature of the second greenhouse reaches the target temperature, cooling is then applied to the first greenhouse. Simultaneously, the residual heat from the first evaporator is used to maintain the temperature of the second greenhouse. Because the target temperature of the second greenhouse is lower, its cooling frequency is usually higher than that of the first greenhouse. By flexibly controlling the refrigerant flow between the first and second greenhouses, combined with real-time temperature monitoring and difference calculation, the refrigerant flow direction can be intelligently controlled, achieving coordinated cooling of the first and second greenhouses. This helps reduce the cooling frequency of the second greenhouse, thereby reducing the number of compressor start-ups and shutdowns and lowering energy consumption.

Detailed Implementation

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

[0049] The following disclosure provides many different embodiments or examples for implementing different structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0050] Dual-temperature, dual-control car refrigerators, as portable refrigeration devices capable of simultaneously meeting freezing and refrigeration needs, feature two independent temperature control zones, allowing for temperature settings tailored to the storage requirements of different foods. These refrigerators typically employ compressor refrigeration technology, achieving a cooling effect down to -18°C, far superior to semiconductor refrigeration technology. However, existing dual-temperature, dual-control car refrigerators suffer from high energy consumption in practical applications. Specifically, due to the need to regulate the temperature of the two compartments, the compressor frequently and intermittently starts and stops. The compression process is the most energy-intensive step in the refrigeration process, as the compressor compresses low-pressure, low-temperature refrigerant vapor into high-pressure hot vapor, consuming a significant amount of electricity. This frequent start-stop operation not only increases user costs but also fails to meet increasingly stringent energy efficiency standards and environmental protection requirements.

[0051] Specifically, suppose a dual-temperature, dual-control vehicle refrigerator is installed on a long-haul transport vehicle to transport foods requiring different temperature preservation levels. The target temperature for the refrigerator compartment is 0°C, used for storing fresh fruits and vegetables; the target temperature for the freezer compartment is -10°C, used for storing frozen meat. During transport, due to fluctuations in the external ambient temperature and frequent opening and closing of the vehicle doors, the temperatures of the two compartments will constantly change. To maintain the target temperature, the system needs to frequently adjust the flow and distribution of refrigerant. Specifically, when the refrigerator compartment temperature rises to 1°C, the system starts the compressor and opens the capillary tube leading to the evaporator in the refrigerator compartment; when the refrigerator compartment temperature drops to -1°C, the system closes the capillary tube. Simultaneously, the freezer compartment undergoes a similar temperature regulation process. This frequent temperature regulation causes the compressor to start and stop multiple times in a short period, and each start-up requires overcoming static friction and initial pressure, consuming a large amount of electrical energy.

[0052] Reference Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 This application proposes a method for controlling the temperature of a vehicle-mounted refrigerator. The vehicle-mounted refrigerator includes a first temperature chamber 100 and a second temperature chamber 200. A first evaporator 110 for transporting refrigerant is arranged around the first temperature chamber 100, and a first capillary tube 120 is connected to the input end of the first evaporator 110. A second evaporator 210 for transporting refrigerant is arranged around the second temperature chamber 200, and the input end of the second evaporator 210 is connected to both the output end of the first evaporator 110 and the second capillary tube 230 via a connecting tee 220. The method for controlling the temperature of the vehicle-mounted refrigerator includes the following steps:

[0053] S100: Obtain the real-time temperature of the first greenhouse 100 and the second greenhouse 200;

[0054] S200: Calculate the first difference between the real-time temperature of the first greenhouse 100 and the target temperature of the first greenhouse 100;

[0055] S300: Calculate the second difference between the real-time temperature of the second greenhouse 200 and the target temperature of the second greenhouse 200;

[0056] S400: When both the first difference and the second difference rise to positive values, control the second capillary tube 230 to transport refrigerant to the second evaporator 210 to cool the second greenhouse 200 separately; when the second difference drops from a positive value to a negative value, control the first capillary tube 120 to transport refrigerant to the first evaporator 110 to cool the first greenhouse 100 and keep the second greenhouse 200 warm.

[0057] Among them, the vehicle refrigerator refers to a portable refrigeration device that can be used in a vehicle, which can be implemented using compressor refrigeration technology; the first greenhouse 100 and the second greenhouse 200 refer to two independent temperature control areas inside the vehicle refrigerator, which can be separated by a partition 300; the evaporator refers to a device used to absorb heat to evaporate the refrigerant, which can be implemented using a coil or plate structure; the capillary tube refers to a thin tube used to reduce refrigerant pressure and control flow, which can be implemented using copper or stainless steel tubes.

[0058] For example, the first target temperature of the first greenhouse 100 is 0°C, used for storing fresh fruits and vegetables; the second target temperature of the second greenhouse 200 is -10°C, used for storing frozen foods. The specific steps of the temperature control method are as follows:

[0059] The real-time temperature of the two greenhouses is acquired every 10 seconds using NTC temperature sensors installed in the first greenhouse 100 and the second greenhouse 200.

[0060] The microprocessor is used to calculate the first difference between the real-time temperature of the first greenhouse 100 and 0°C.

[0061] Calculate the second difference between the real-time temperature of the second greenhouse 200 and -10℃.

[0062] When both the first and second temperature differences are detected to rise to positive values ​​(e.g., the temperature of the first greenhouse 100 is 1°C and the temperature of the second greenhouse 200 is -9°C), the control system opens the solenoid valve of the second capillary tube 230 and closes the solenoid valve of the first capillary tube 120, allowing the refrigerant to flow only through the second capillary tube 230 to the second evaporator 210, thus cooling the second greenhouse 200 alone. When the second temperature difference is detected to drop from a positive value to a negative value (e.g., the temperature of the second greenhouse 200 drops to -11°C), the control system closes the solenoid valve of the second capillary tube 230 and opens the solenoid valve of the first capillary tube 120, allowing the refrigerant to flow through the first capillary tube 120 to the first evaporator 110, thus cooling the first greenhouse 100. Simultaneously, since the output of the first evaporator 110 is connected to the second evaporator 210, some of the low-temperature refrigerant will flow through the second evaporator 210, thereby providing insulation for the second greenhouse 200. Using this control method, the vehicle-mounted refrigerator can flexibly adjust its cooling strategy according to the real-time temperature changes of the two compartments, effectively reducing the number of compressor start-ups and shutdowns, lowering energy consumption, and ensuring that the temperature control accuracy of the two compartments is within ±1℃.

[0063] As can be seen from the above, the vehicle refrigerator temperature control method provided by the present invention obtains the real-time temperatures of the two greenhouses and calculates the difference between them and the target temperature. When both the first difference and the second difference rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are higher than the target temperature. Cooling is prioritized for the second greenhouse 200, which has a lower temperature requirement. Once the real-time temperature of the second greenhouse 200 reaches the target temperature, cooling is then applied to the first greenhouse 100. Simultaneously, the residual cooling from the first evaporator 110 is used to maintain the temperature of the second greenhouse 200. Because the target temperature of the second greenhouse 200 is lower, its cooling frequency is usually higher than that of the first greenhouse 100. By flexibly controlling the refrigerant flow between the first greenhouse 100 and the second greenhouse 200, combined with real-time temperature monitoring and difference calculation, the flow direction of the refrigerant can be intelligently controlled, achieving coordinated cooling of the first greenhouse 100 and the second greenhouse 200. This helps reduce the cooling frequency of the second greenhouse 200, thereby reducing the number of compressor start-ups and shutdowns and lowering energy consumption.

[0064] In one embodiment, the vehicle-mounted refrigerator temperature control method further includes the following steps:

[0065] Obtain the ambient temperature of the vehicle refrigerator;

[0066] When the real-time temperature of the first greenhouse 100 and the real-time temperature of the second greenhouse 200 are both ambient temperatures, the first capillary tube 120 is controlled to transport refrigerant to the first evaporator 110 to cool the first greenhouse 100 and the second greenhouse 200 simultaneously; when the first difference decreases to a negative value, the second capillary tube 230 is controlled to transport refrigerant to the second evaporator 210 to cool the second greenhouse 200 separately.

[0067] Specifically, the temperature control method of this application first obtains the ambient temperature of the vehicle refrigerator through a temperature sensor. This ambient temperature may be the temperature outside the refrigerator or the initial temperature inside the refrigerator before cooling begins. Next, the system determines whether the real-time temperatures of the first temperature chamber 100 and the second temperature chamber 200 are equal to the ambient temperature. If so, it indicates that the refrigerator has just started working or has not been used for a long time, and rapid cooling is required.

[0068] In this configuration, the control system instructs the first capillary tube 120 to deliver refrigerant to the first evaporator 110. Since the first evaporator 110 is connected to the second evaporator 210 via a connecting tee 220, the refrigerant flows through both evaporators simultaneously, thus achieving synchronous cooling of the first greenhouse 100 and the second greenhouse 200. This method can rapidly lower the temperature of both greenhouses, improving cooling efficiency.

[0069] As the cooling process proceeds, the system continuously monitors the difference between the real-time temperature of the first greenhouse 100 and the first target temperature (i.e., the first difference). When the first difference gradually decreases from a positive value to a negative value, it indicates that the temperature of the first greenhouse 100 has reached or fallen below the target temperature. At this point, in order to avoid the temperature of the first greenhouse 100 becoming too low and to save energy, the control system will switch the cooling strategy.

[0070] By adopting the above technical solution, the refrigeration strategy can be flexibly adjusted according to the actual needs of different greenhouses, which not only ensures the refrigeration effect but also improves energy utilization efficiency.

[0071] In actual use, car refrigerators typically have limited storage space for portability. Car refrigerators employing dual-temperature, dual-control systems further compress this space by having two internal temperature chambers, making it difficult to cool large items. Therefore, in one embodiment, a detachable partition 300 is provided between the first temperature chamber 100 and the second temperature chamber 200. The partition 300 can be inserted into or removed from the car refrigerator to separate or connect the first temperature chamber 100 and the second temperature chamber 200. The car refrigerator temperature control method further includes the following steps:

[0072] Obtain the insertion information of the middle partition 300;

[0073] The operating mode of the vehicle refrigerator is adjusted based on the inserted information. The operating modes include dual-temperature cooling mode and single-temperature cooling mode.

[0074] Specifically, the insertion information of the middle partition 300 can be obtained in several ways. One method is to install a magnetic sensor inside the refrigerator. When the middle partition is inserted, the sensor can detect a change in the magnetic field, thus identifying the presence of the middle partition. Another method is to use a mechanical switch or photoelectric sensor. When the middle partition 300 is inserted into place, these sensors can be triggered, sending a signal to the control system.

[0075] Based on the information obtained regarding the insertion of the partition 300, the vehicle refrigerator's control system can intelligently adjust its operating mode. When the insertion of the partition 300 is detected, the system automatically switches to a dual-temperature cooling mode, allowing independent temperature control for both compartments. In this mode, the first compartment 100 and the second compartment 200 can be set with different target temperatures to meet different needs for refrigeration and freezing. Conversely, when the removal of the partition 300 is detected, the system switches to a single-temperature cooling mode, treating the entire space as a single large storage area and controlling the temperature uniformly.

[0076] By adopting the above technical solution, the vehicle refrigerator temperature control method of this application can effectively solve the problem of insufficient flexibility in the use of traditional vehicle refrigerators. It not only meets the diverse needs of users in different scenarios, but also improves energy efficiency through intelligent temperature control. Compared with traditional vehicle refrigerators with fixed partitions, the method of this application has significant advantages in both space utilization and temperature control. For example, when users need to store large food items, the middle partition 300 can be removed to obtain more storage space; and when different types of food need to be stored simultaneously, it can quickly switch to a dual-temperature mode to achieve precise temperature control. This flexibility not only improves the user experience, but also optimizes energy use according to actual needs, reducing unnecessary energy waste.

[0077] In one embodiment, the insertion information is either separation status information indicating that the partition 300 is inserted into the vehicle refrigerator to separate the first greenhouse 100 and the second greenhouse 200, or connection status information indicating that the partition 300 is removed from the vehicle refrigerator to connect the first greenhouse 100 and the second greenhouse 200; adjusting the operating mode of the vehicle refrigerator based on the insertion information includes the following steps:

[0078] When the inserted information is the separated state information, the vehicle refrigerator is controlled to enter the dual-temperature cooling mode. During the operation of the dual-temperature cooling mode, the first target temperature of the first greenhouse 100 is greater than the second target temperature of the second greenhouse 200. The first target temperature and the second target temperature are respectively the target temperatures of the first greenhouse 100 and the second greenhouse 200 in the dual-temperature cooling mode.

[0079] When the inserted information is a connected state information, the vehicle refrigerator is controlled to enter a single-temperature cooling mode; during the operation of the single-temperature cooling mode, the first capillary tube 120 is controlled to transport refrigerant to the first evaporator 110 so as to cool the first greenhouse 100 and the second greenhouse 200 at the same time, and the target temperature of the first greenhouse 100 and the second greenhouse 200 is the third target temperature.

[0080] The third target temperature can be equal to the first target temperature or the second target temperature, or it can be customized by the user.

[0081] By employing the above technical solution and acquiring the insertion information of the partition 300, the operating mode of the vehicle refrigerator can be flexibly adjusted. This method allows switching between dual-temperature cooling and single-temperature cooling modes according to the user's actual needs, improving the flexibility and practicality of the vehicle refrigerator.

[0082] In one embodiment, the single-temperature cooling mode includes the following steps:

[0083] Calculate the third difference between the real-time temperature of the first greenhouse 100 and the third target temperature;

[0084] Calculate the fourth difference between the real-time temperature of the second greenhouse 200 and the third target temperature;

[0085] When both the third and fourth differences are negative, the first capillary tube 120 and the second capillary tube 230 are controlled to stop transporting refrigerant.

[0086] The vehicle-mounted refrigerator temperature control method proposed in this application operates in a single-temperature cooling mode. In this mode, the first greenhouse 100 and the second greenhouse 200 are connected, forming a large temperature control space. The third target temperature is the target temperature of this large space. By calculating the difference between the real-time temperatures of the two greenhouses and the third target temperature, the temperature of the entire space can be controlled more precisely.

[0087] Specifically, the temperature control method of this application first calculates the difference between the real-time temperatures of the two greenhouses and the third target temperature. The third difference is the difference between the real-time temperature of the first greenhouse (100°C) and the third target temperature, and the fourth difference is the difference between the real-time temperature of the second greenhouse (200°C) and the third target temperature. These two differences reflect the temperature distribution of the entire space.

[0088] By adopting the above technical solution and acquiring the temperatures of the two greenhouses, the temperature distribution of the entire space can be better reflected, avoiding situations where the temperature in certain areas is too low or too high. Simultaneously, by promptly stopping the transport of refrigerant, energy can be effectively saved, improving the energy efficiency of the vehicle-mounted refrigerator.

The second greenhouse 200 is surrounded by a second evaporator 210 for transporting refrigerant, and the input end of the second evaporator 210 is simultaneously connected to the output end of the first evaporator 110 and a second capillary tube 230 via a connecting tee 220.

[0093] The refrigeration control module 440 is used to control the second capillary tube 230 to transport refrigerant to the second evaporator 210 when both the first difference and the second difference rise to positive values, so as to cool the second greenhouse 200 separately; and to control the first capillary tube 120 to transport refrigerant to the first evaporator 110 when the second difference drops from a positive value to a negative value, so as to cool the first greenhouse 100 and keep the second greenhouse 200 warm.

[0094] By adopting the above technical solution, the real-time temperatures of the two greenhouses are acquired and the difference between these temperatures and the target temperature is calculated. When both the first and second differences rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are higher than the target temperature. Cooling is then prioritized for the second greenhouse 200, which has a lower temperature requirement. Once the real-time temperature of the second greenhouse 200 reaches the target temperature, cooling is then applied to the first greenhouse 100. Simultaneously, the residual heat from the first evaporator 110 is used to maintain the temperature of the second greenhouse 200. Because the target temperature of the second greenhouse 200 is lower, its cooling frequency is typically higher than that of the first greenhouse 100. Through flexible refrigerant flow between the first greenhouse 100 and the second greenhouse 200, combined with real-time temperature monitoring and difference calculation, the refrigerant flow direction can be intelligently controlled, achieving coordinated cooling of both greenhouses. This helps reduce the cooling frequency of the second greenhouse 200, thereby reducing the number of compressor start-ups and shutdowns and lowering energy consumption.

[0095] In one embodiment, a partition 300 is also included, which is detachably disposed between the first greenhouse 100 and the second greenhouse 200. The partition 300 can separate or connect the first greenhouse 100 and the second greenhouse 200.

[0096] By adopting the above technical solution, the vehicle refrigerator temperature control method of this application can effectively solve the problem of insufficient flexibility in the use of traditional vehicle refrigerators. It not only meets the diverse needs of users in different scenarios, but also improves energy efficiency through intelligent temperature control. Compared with traditional vehicle refrigerators with fixed partitions, the method of this application has significant advantages in both space utilization and temperature control. For example, when users need to store large food items, the middle partition 300 can be removed to obtain more storage space; and when different types of food need to be stored simultaneously, it can quickly switch to a dual-temperature mode to achieve precise temperature control. This flexibility not only improves the user experience, but also optimizes energy use according to actual needs, reducing unnecessary energy waste.

[0097] In one embodiment, a magnetic switch 310 is provided between the first greenhouse 100 and the second greenhouse 200. When the partition 300 is provided between the first greenhouse 100 and the second greenhouse 200, the magnetic switch 310 adjusts the vehicle refrigerator from single-temperature cooling mode to dual-temperature cooling module.

[0098] By employing the above technical solution, an automatic switching of the vehicle refrigerator's operating mode is achieved by installing a magnetic switch 310 between the first greenhouse 100 and the second greenhouse 200. When the middle partition 300 is inserted between the first greenhouse 100 and the second greenhouse 200, the magnetic switch 310 can sense the presence of the middle partition 300, thereby automatically switching the vehicle refrigerator's operating mode from single-temperature cooling mode to dual-temperature cooling mode. This design not only simplifies user operation but also improves the intelligence level of the vehicle refrigerator.

[0099] In one embodiment, the temperature acquisition module 410 is further configured to acquire the ambient temperature of the vehicle refrigerator; the refrigeration control module 440 is further configured to control the first capillary tube 120 to transport refrigerant to the first evaporator 110 when the real-time temperature of the first greenhouse 100 and the real-time temperature of the second greenhouse 200 are both ambient temperatures, so as to simultaneously refrigerate the first greenhouse 100 and the second greenhouse 200; and to control the second capillary tube 230 to transport refrigerant to the second evaporator 210 when the first difference decreases to a negative value, so as to refrigerate the second greenhouse 200 separately.

[0100] In one embodiment, the vehicle refrigerator further includes an insertion acquisition module and a mode adjustment module. The insertion acquisition module is used to acquire the insertion information of the partition 300. The mode adjustment module is used to adjust the operating mode of the vehicle refrigerator based on the insertion information. The operating modes include a dual-temperature cooling mode and a single-temperature cooling mode.

This application provides an electronic device 500, including: a processor 510 and a memory 520. The processor 510 and the memory 520 are interconnected and communicate with each other through a communication bus 530 and / or other forms of connection mechanism (not shown). The memory 520 stores a computer program executable by the processor 510. When the computing device is running, the processor 510 executes the computer program to execute the method in any optional implementation of the above embodiment to achieve the following functions: by acquiring the real-time temperatures of the two greenhouses and calculating the difference with the target temperature, when both the first difference and the second difference rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are higher than the target temperature. The second greenhouse 200, which has a lower temperature requirement, is cooled first. When the real-time temperature of the second greenhouse 200 reaches the target temperature, the first greenhouse 100 is cooled. At the same time, the residual cold of the first evaporator 110 is used to keep the second greenhouse 200 warm. Because the target temperature of the second greenhouse 200 is lower, the cooling frequency of the second greenhouse 200 is usually higher than that of the first greenhouse 100. By flexibly controlling the flow of refrigerant between the first greenhouse 100 and the second greenhouse 200, combined with real-time temperature monitoring and differential calculation, the flow direction of the refrigerant can be intelligently controlled to achieve coordinated cooling of the first greenhouse 100 and the second greenhouse 200. This helps to reduce the cooling frequency of the second greenhouse 200, thereby reducing the number of compressor start-ups and shutdowns and reducing energy consumption.

[0102] This application provides a storage medium storing a computer program. When the computer program is executed by a processor, it executes the method in any optional implementation of the above embodiments to achieve the following functions: by acquiring the real-time temperatures of two greenhouses and calculating the difference between them and the target temperature, when both the first difference and the second difference rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are higher than the target temperature. The second greenhouse 200, which has a lower temperature requirement, is prioritized for cooling. After the real-time temperature of the second greenhouse 200 reaches the target temperature, the first greenhouse 100 is then cooled. At the same time, the residual cooling of the first evaporator 110 is used to keep the second greenhouse 200 warm. Because the target temperature of the second greenhouse 200 is lower, the cooling frequency of the second greenhouse 200 is usually higher than that of the first greenhouse 100. By flexibly controlling the flow of refrigerant between the first greenhouse 100 and the second greenhouse 200, combined with real-time temperature monitoring and differential calculation, the flow direction of the refrigerant can be intelligently controlled to achieve coordinated cooling of the first greenhouse 100 and the second greenhouse 200. This helps to reduce the cooling frequency of the second greenhouse 200, thereby reducing the number of compressor start-ups and shutdowns and reducing energy consumption.
