Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration appliances, and in particular to a vehicle refrigerator temperature control method, a vehicle refrigerator, an electronic device and a storage medium. Background Art

[0002] A dual-temperature dual-control car refrigerator is a portable refrigeration device that can meet both freezing and refrigeration needs. It has two independent temperature control areas, allowing users to set different temperatures according to the storage requirements of different foods. This type of refrigerator usually uses compressor refrigeration technology, and the cooling effect can reach -18℃, which is much better than semiconductor refrigeration technology. Dual-temperature dual-control car refrigerators can achieve rapid cooling, and some models can drop to 0℃ within 15 minutes.

[0003] Most of the existing dual-temperature dual-control car refrigerators use two capillaries to transport refrigerant to the evaporators of the two greenhouses to achieve refrigeration (such as the attached Figure 1 As shown). When both the refrigerator and freezer compartments need to be refrigerated, the refrigerant enters the refrigerator compartment evaporator and the freezer compartment evaporator through two capillaries respectively, and the two compartments are refrigerated at the same time. When the refrigerator compartment reaches the specified temperature or no longer needs to be refrigerated, the refrigerant enters only the freezer compartment evaporator through one capillary tube for refrigeration.

[0004] In the refrigeration process, the step with the highest energy consumption is the compression process. In a vapor compression refrigeration cycle system, the compressor compresses low-pressure and low-temperature refrigerant vapor into high-pressure hot steam. This process consumes a lot of electricity because the compressor needs to overcome the resistance of the system and compress the refrigerant vapor to a higher pressure. Since the above-mentioned dual-temperature and dual-control car refrigerator needs to regulate the temperature of the two greenhouses, the compressor will frequently start and stop for a short time, so there is a problem of high energy consumption. This not only increases the user's cost of use, but also does not meet the current increasingly stringent energy efficiency standards and environmental protection requirements. In addition, the high energy consumption problem will also limit the use time of the car refrigerator, especially when the vehicle power supply is limited. Summary of the invention

[0005] The object of the present invention is to provide a vehicle refrigerator temperature control method, a vehicle 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 vehicle refrigerator temperature control method for controlling the temperature of the vehicle refrigerator, wherein the vehicle refrigerator comprises a first greenhouse and a second greenhouse, wherein the first greenhouse is surrounded by a first evaporator for transporting a refrigerant, wherein an input end of the first evaporator is connected to a first capillary tube, and the second greenhouse is surrounded by a second evaporator for transporting a refrigerant, wherein the input end of the second evaporator is connected to an output end of the first evaporator and a second capillary tube through a connecting tee, wherein the vehicle refrigerator temperature control method comprises the following steps: Acquiring real-time temperatures of the first greenhouse and the second greenhouse; calculating a first difference between the real-time temperature of the first greenhouse and the target temperature of the first greenhouse; calculating a second difference between the real-time temperature of the second greenhouse and the target temperature of the second greenhouse; 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 alone; 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 keep the second greenhouse warm.

[0007] The vehicle refrigerator temperature control method provided by the present invention obtains the real-time temperatures of the two greenhouses and calculates the difference with the target temperature. When the first difference and the second difference both rise to positive values, the real-time temperatures of the first greenhouse and the second greenhouse are both higher than the target temperature, and the second greenhouse with a lower temperature requirement is refrigerated first. When the real-time temperature of the second greenhouse reaches the target temperature, the first greenhouse is refrigerated again, and the second greenhouse is kept warm by using the residual cold of the first evaporator. Since the target temperature of the second greenhouse is lower, the refrigeration frequency of the second greenhouse is usually higher than that of the first greenhouse. Through the flexible flow of the refrigerant between the first greenhouse and the second greenhouse, combined with real-time temperature monitoring and difference calculation, the flow direction of the refrigerant can be intelligently controlled to achieve coordinated refrigeration of the first greenhouse and the second greenhouse, which helps to reduce the refrigeration frequency of the second greenhouse, thereby reducing the number of starts and stops of the compressor and reducing energy consumption.

[0008] Furthermore, the vehicle refrigerator temperature control method further comprises the following steps: Obtaining the ambient temperature of the vehicle refrigerator; When the real-time temperature of the first greenhouse and the real-time temperature of the second greenhouse are both the ambient temperature, the first capillary tube is controlled to transport the refrigerant to the first evaporator to cool the first greenhouse and the second greenhouse at the same time; when the first difference decreases to a negative value, the second capillary tube is controlled to transport the refrigerant to the second evaporator to cool the second greenhouse alone.

[0009] 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 the energy utilization efficiency.

[0010] Furthermore, a middle partition is detachably provided between the first greenhouse and the second greenhouse, and the middle partition can be inserted into or removed from the vehicle refrigerator to separate or connect the first greenhouse and the second greenhouse. The vehicle refrigerator temperature control method further includes the following steps: Obtaining the insertion information of the middle partition; An operation mode of the vehicle refrigerator is adjusted based on the insertion information, and the operation mode includes a dual-temperature refrigeration mode and a single-temperature refrigeration mode.

[0011] By adopting the above technical solution, the temperature control method of the vehicle refrigerator of the present application can effectively solve the problem of insufficient flexibility in the use of traditional vehicle refrigerators. It can not only meet the diverse needs of users in different scenarios, but also improve energy utilization efficiency through intelligent temperature control. Compared with traditional vehicle refrigerators with fixed partitions, the method of the present application has obvious advantages in space utilization and temperature control. For example, when the user needs to store large food, the middle partition can be removed to obtain a larger storage space; and when different types of food need to be stored at the same time, it can be quickly switched to 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 and reduces unnecessary energy waste.

[0012] Further, the insertion information is partition state information indicating that the middle partition is inserted into the vehicle refrigerator to separate the first greenhouse and the second greenhouse, or connection state information indicating that the middle partition is taken out of the vehicle refrigerator to connect the first greenhouse and the second greenhouse; and adjusting the operation mode of the vehicle refrigerator based on the insertion information comprises the following steps: When the insertion information is separation state information, the vehicle refrigerator is controlled to enter the dual-temperature refrigeration mode, and during the operation of the dual-temperature refrigeration mode, the first target temperature of the first greenhouse is greater than the second target temperature of the second greenhouse; When the insertion information is connectivity status information, the vehicle refrigerator is controlled to enter the single-temperature refrigeration mode; during the operation of the single-temperature refrigeration mode, the first capillary tube is controlled to transport refrigerant to the first evaporator to cool the first greenhouse and the second greenhouse at the same time, and the target temperatures of the first greenhouse and the second greenhouse are both the third target temperature.

[0013] By adopting the above technical solution, the operation mode of the vehicle refrigerator can be flexibly adjusted by obtaining the insertion information of the middle partition. This method can switch between the dual-temperature cooling mode and the single-temperature cooling mode according to the actual needs of the user, thereby improving the flexibility and practicality of the vehicle refrigerator.

[0014] Furthermore, operating the single-temperature refrigeration mode includes the following steps: calculating a third difference between the real-time temperature of the first greenhouse and a third target temperature; calculating a fourth difference between the real-time temperature of the second greenhouse and the third target temperature; When the third difference and the fourth difference are negative values, the first capillary tube and the second capillary tube are controlled to stop transporting the refrigerant.

[0015] By adopting the above technical solution, by obtaining the temperature of the two greenhouses, the temperature distribution of the entire space can be better reflected, avoiding the situation where the temperature in some areas is too low or too high. At the same time, by stopping the transportation of refrigerant in time, energy can be effectively saved and the energy efficiency of the car refrigerator can be improved.

[0016] In a second aspect, the present application further provides a vehicle refrigerator, comprising a first greenhouse and a second greenhouse, wherein the first greenhouse is surrounded by a first evaporator for transporting a refrigerant, an input end of the first evaporator is connected to a first capillary tube, and the second greenhouse is surrounded by a second evaporator for transporting a refrigerant, the input end of the second evaporator is simultaneously connected to the output end of the first evaporator and the second capillary tube through a connecting tee, and the vehicle refrigerator further comprises: A temperature acquisition module, used to acquire the real-time temperatures of the first greenhouse and the second greenhouse; a first calculation module, configured to calculate a first difference between the real-time temperature of the first greenhouse and the target temperature of the first greenhouse; a second calculation module, configured to calculate a second difference between the real-time temperature of the second greenhouse and the target temperature of the second greenhouse; The refrigeration control module is used to control the second capillary tube to transport the refrigerant to the second evaporator when the first difference and the second difference both rise to positive values, so as to cool the second greenhouse alone; and to control the first capillary tube to transport the refrigerant to the first evaporator when the second difference decreases from a positive value to a negative value, so as to cool the first greenhouse and keep the second greenhouse warm.

[0017] Furthermore, it also includes a middle partition, which is detachably arranged between the first greenhouse and the second greenhouse, and the middle partition can separate or connect the first greenhouse and the second greenhouse.

[0018] Furthermore, a magnetically controlled switch is provided between the first greenhouse and the second greenhouse. When the middle partition is provided in the first greenhouse and the second greenhouse, the magnetically controlled switch adjusts the vehicle refrigerator from a single-temperature cooling mode to a dual-temperature cooling module.

[0019] By adopting the above technical solution, a magnetic control switch is set between the first greenhouse and the second greenhouse to realize the automatic switching of the working mode of the vehicle refrigerator. When the middle partition is inserted between the first greenhouse and the second greenhouse, the magnetic control switch can sense the existence of the middle partition, thereby automatically switching the working mode of the vehicle refrigerator from the single-temperature cooling mode to the dual-temperature cooling mode. This design not only simplifies user operation, but also improves the intelligence level of the vehicle refrigerator.

[0020] In a third aspect, the present application provides an electronic device, comprising a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, the steps in the method provided in the first aspect are performed.

[0021] In a fourth aspect, the present application provides a storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, the steps in the method provided in the first aspect are performed.

[0022] As can be seen from the above, the vehicle refrigerator temperature control method provided by the present invention obtains the real-time temperature of the two greenhouses and calculates the difference with the target temperature. When the first difference and the second difference both rise to positive values, the real-time temperatures of the first greenhouse and the second greenhouse are higher than the target temperature, and the second greenhouse with a lower temperature requirement is refrigerated first. When the real-time temperature of the second greenhouse reaches the target temperature, the first greenhouse is refrigerated again, and the second greenhouse is kept warm by using the residual cold of the first evaporator. Since the target temperature of the second greenhouse is lower, the refrigeration frequency of the second greenhouse is usually higher than that of the first greenhouse. Through the flexible flow of the refrigerant between the first greenhouse and the second greenhouse, combined with real-time temperature monitoring and difference calculation, the flow direction of the refrigerant can be intelligently controlled to achieve coordinated refrigeration of the first greenhouse and the second greenhouse, which helps to reduce the refrigeration frequency of the second greenhouse, thereby reducing the number of starts and stops of the compressor and reducing energy consumption.

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0033] As a portable refrigeration device that can meet the needs of freezing and refrigeration at the same time, the dual-temperature dual-control car refrigerator has two independent temperature control areas, and different temperatures can be set according to the storage requirements of different foods. This type of refrigerator usually uses compressor refrigeration technology, and the refrigeration effect can reach -18°C, which is much better than semiconductor refrigeration technology. However, the existing dual-temperature dual-control car refrigerator has the problem of high energy consumption in practical applications. Specifically, due to the need to regulate the temperature of the two greenhouses, the compressor will frequently start and stop for a short time. In the refrigeration process, the compression process is the step with the highest energy consumption. The compressor compresses the low-pressure and low-temperature refrigerant vapor into high-pressure hot vapor, which consumes a lot of electricity. This frequent start and stop not only increases the user's cost of use, but also does not meet the current increasingly stringent energy efficiency standards and environmental protection requirements.

[0034] Specifically, assume that a dual-temperature dual-control vehicle refrigerator is installed on a long-distance transport vehicle to transport food that needs to be stored at different temperatures. The target temperature of the refrigerator is 0°C, which is used to store fresh fruits and vegetables; the target temperature of the freezer is -10°C, which is used to store frozen meat. During transportation, the temperature of the two greenhouses will continue to change due to fluctuations in the external ambient temperature and the frequent opening and closing of the car door. In order to maintain the target temperature, the system needs to frequently adjust the flow and distribution of the refrigerant. Specifically, when the temperature of the refrigerator rises to 1°C, the system will start the compressor and open the capillary leading to the evaporator of the refrigerator; when the temperature of the refrigerator drops to -1°C, the system will close the capillary again. At the same time, the freezer is also undergoing a similar temperature adjustment process. This frequent temperature adjustment causes the compressor to start and stop multiple times in a short period of time. Each start needs to overcome static friction and initial pressure, consuming a lot of electricity.

[0035] Reference Figure 2 , Attachment Figure 3 , Attachment Figure 4 The present application proposes a vehicle refrigerator temperature control method for controlling the temperature of the vehicle refrigerator, wherein the vehicle refrigerator comprises a first greenhouse 100 and a second greenhouse 200, wherein the first greenhouse 100 surrounds a first evaporator 110 for transporting a refrigerant, wherein an input end of the first evaporator 110 is connected to a first capillary tube 120, and the second greenhouse 200 surrounds a second evaporator 210 for transporting a refrigerant, wherein an input end of the second evaporator 210 is connected to an output end of the first evaporator 110 and a second capillary tube 230 through a connecting tee 220; the vehicle refrigerator temperature control method comprises the following steps: S100: Acquire the real-time temperatures of the first greenhouse 100 and the second greenhouse 200; S200: Calculating a first difference between the real-time temperature of the first greenhouse 100 and the target temperature 100 of the first greenhouse; S300: Calculating a second difference between the real-time temperature of the second greenhouse 200 and the target temperature of the second greenhouse 200; S400: When both the first difference and the second difference rise to positive values, the second capillary tube 230 is controlled to transport the refrigerant to the second evaporator 210 to cool the second greenhouse 200 alone; when the second difference drops from a positive value to a negative value, the first capillary tube 120 is controlled to transport the refrigerant to the first evaporator 110 to cool the first greenhouse 100 and keep the second greenhouse 200 warm.

[0036] Among them, the vehicle refrigerator refers to a portable refrigeration device that can be used in a vehicle, which can be specifically implemented by 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 specifically implemented by separating them with a middle partition 300; the evaporator refers to a device for absorbing heat to evaporate the refrigerant, which can be specifically implemented by a coil or plate structure; the capillary refers to a thin tube used to reduce the refrigerant pressure and control the flow rate, which can be specifically implemented by a copper tube or a stainless steel tube.

[0037] For example, the first target temperature of the first greenhouse 100 is 0° C., which is used to store fresh fruits and vegetables; the second target temperature of the second greenhouse 200 is -10° C., which is used to store frozen food. The specific steps of the temperature control method are as follows: Through the NTC temperature sensors installed in the first greenhouse 100 and the second greenhouse 200, the real-time temperatures of the two greenhouses are acquired every 10 seconds.

[0038] The first difference between the real-time temperature of the first greenhouse 100 and 0° C. is calculated using the microprocessor.

[0039] A second difference between the real-time temperature of the second greenhouse 200 and -10°C is calculated.

[0040] When it is detected that both the first difference and the second difference rise to positive values ​​(for example, the temperature of the first greenhouse 100 is 1°C and the temperature of the second greenhouse 200 is -9°C), the control system will open the solenoid valve of the second capillary tube 230 and close the solenoid valve of the first capillary tube 120, so that the refrigerant flows to the second evaporator 210 only through the second capillary tube 230, and cools the second greenhouse 200 alone; when it is detected that the second difference drops from a positive value to a negative value (for example, the temperature of the second greenhouse 200 drops to -11°C), the control system will close the solenoid valve of the second capillary tube 230 and open the solenoid valve of the first capillary tube 120, so that the refrigerant flows to the first evaporator 110 through the first capillary tube 120, and cools the first greenhouse 100. At the same time, since the output end of the first evaporator 110 is connected to the second evaporator 210, part of the low-temperature refrigerant will flow through the second evaporator 210, thereby keeping the second greenhouse 200 warm. Through this control method, the car refrigerator can flexibly adjust the refrigeration strategy according to the real-time temperature changes of the two greenhouses, effectively reducing the start and stop times of the compressor and reducing energy consumption, while ensuring that the temperature control accuracy of the two greenhouses is within the range of ±1°C.

[0041] 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 with the target temperature. When the first difference and the second difference both rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are both higher than the target temperature, and the second greenhouse 200 with a lower temperature requirement is refrigerated first. When the real-time temperature of the second greenhouse 200 reaches the target temperature, the first greenhouse 100 is refrigerated again, and the second greenhouse 200 is kept warm by using the residual cold of the first evaporator 110. Since the target temperature of the second greenhouse 200 is lower, the refrigeration frequency of the second greenhouse 200 is usually higher than that of the first greenhouse 100. Through the flexible flow of the refrigerant 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 to achieve coordinated refrigeration of the first greenhouse 100 and the second greenhouse 200, which helps to reduce the refrigeration frequency of the second greenhouse 200, thereby reducing the number of starts and stops of the compressor and reducing energy consumption.

[0042] In one embodiment, the vehicle refrigerator temperature control method further includes the following steps: Obtaining the ambient temperature of the vehicle refrigerator; When the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are both the ambient temperature, the first capillary tube 120 is controlled to transport the refrigerant to the first evaporator 110 to cool the first greenhouse 100 and the second greenhouse 200 at the same time; when the first difference decreases to a negative value, the second capillary tube 230 is controlled to transport the refrigerant to the second evaporator 210 to cool the second greenhouse 200 alone.

[0043] Specifically, the temperature control method of the present 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 it may be the initial temperature inside the refrigerator before refrigeration. Next, the system determines whether the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are both equal to the ambient temperature. If so, it means that the refrigerator has just started to work or has not been used for a long time, and it needs to be cooled quickly.

[0044] In this case, the control system will instruct the first capillary tube 120 to deliver the refrigerant to the first evaporator 110. Since the first evaporator 110 is connected to the second evaporator 210 through the connecting tee 220, the refrigerant will flow through the two evaporators at the same time, thereby realizing synchronous cooling of the first greenhouse 100 and the second greenhouse 200. This method can quickly reduce the temperature of the two greenhouses and improve the cooling efficiency.

[0045] As the cooling process proceeds, the system will continuously monitor 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 and becomes a negative value, it means that the temperature of the first greenhouse 100 has reached or is lower than the target temperature. At this time, in order to avoid the temperature of the first greenhouse 100 being too low and to save energy, the control system will switch the cooling strategy.

[0046] 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 the energy utilization efficiency.

[0047] In the actual use of a car refrigerator, its storage space is usually small for the sake of portability. However, a car refrigerator adopting a dual-temperature dual-control method has two greenhouses inside, which further compresses its storage space and makes it difficult to refrigerate large items. To this end, in one embodiment, a detachable middle partition 300 is provided between the first greenhouse 100 and the second greenhouse 200. The middle partition 300 can be inserted into or removed from the car refrigerator to separate or connect the first greenhouse 100 and the second greenhouse 200. The car refrigerator temperature control method also includes the following steps: Obtaining the insertion information of the middle partition plate 300; The operation mode of the vehicle refrigerator is adjusted based on the inserted information, and the operation modes include a dual-temperature refrigeration mode and a single-temperature refrigeration mode.

[0048] Specifically, the insertion information of the middle partition 300 can be obtained in a variety of ways. One method is to install a magnetic sensor inside the refrigerator. When the middle partition is inserted, the sensor can detect the change in the magnetic field, thereby identifying the presence of the middle partition. Another method is to use a mechanical switch or a photoelectric sensor. When the middle partition 300 is inserted into place, these sensors can be triggered to send a signal to the control system.

[0049] Based on the information obtained about the insertion of the middle partition 300, the control system of the vehicle refrigerator can intelligently adjust the operating mode. When the insertion of the middle partition 300 is detected, the system will automatically switch to the dual-temperature cooling mode, allowing the two greenhouses to be independently controlled. In this mode, different target temperatures can be set for the first greenhouse 100 and the second greenhouse 200 to meet the different needs of refrigeration and freezing. On the contrary, when it is detected that the middle partition 300 is removed, the system will switch to the single-temperature cooling mode, treating the entire space as a large storage area and controlling the temperature uniformly.

[0050] By adopting the above technical solution, the temperature control method of the vehicle refrigerator of the present application can effectively solve the problem of insufficient flexibility in the use of traditional vehicle refrigerators. It can not only meet the diverse needs of users in different scenarios, but also improve energy utilization efficiency through intelligent temperature control. Compared with traditional vehicle refrigerators with fixed partitions, the method of the present application has obvious advantages in space utilization and temperature control. For example, when the user needs to store large food, the middle partition 300 can be removed to obtain a larger storage space; and when different types of food need to be stored at the same time, it can be quickly switched to 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 and reduces unnecessary energy waste.

[0051] In one embodiment, the insertion information is partition state information indicating that the middle partition 300 is inserted into the vehicle refrigerator to separate the first greenhouse 100 and the second greenhouse 200, or the connection state information indicating that the middle partition 300 is taken out of the vehicle refrigerator to connect the first greenhouse 100 and the second greenhouse 200; adjusting the operation mode of the vehicle refrigerator based on the insertion information includes the following steps: When the insertion information is separation state information, the vehicle refrigerator is controlled to enter the dual-temperature refrigeration mode. During the operation of the dual-temperature refrigeration 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 refrigeration mode. When the insertion information is the connection status information, the vehicle refrigerator is controlled to enter the single-temperature refrigeration mode; during the operation of the single-temperature refrigeration mode, the first capillary tube 120 is controlled to transport the refrigerant to the first evaporator 110 to cool the first greenhouse 100 and the second greenhouse 200 at the same time, and the target temperatures of the first greenhouse 100 and the second greenhouse 200 are both the third target temperature.

[0052] The third target temperature may be equal to the first target temperature or the second target temperature, or may be customized by the user.

[0053] By adopting the above technical solution, the operation mode of the vehicle refrigerator can be flexibly adjusted by obtaining the insertion information of the middle partition 300. This method can switch between the dual-temperature refrigeration mode and the single-temperature refrigeration mode according to the actual needs of the user, thereby improving the flexibility and practicality of the vehicle refrigerator.

[0054] In one embodiment, the single temperature cooling mode includes the following steps: calculating a third difference between the real-time temperature of the first greenhouse 100 and the third target temperature; calculating a fourth difference between the real-time temperature of the second greenhouse 200 and the third target temperature; When the third difference and the fourth difference are both negative values, the first capillary tube 120 and the second capillary tube 230 are controlled to stop transporting the refrigerant.

[0055] The vehicle refrigerator temperature control method proposed in the present application is performed in a single temperature refrigeration mode. In this mode, the first greenhouse 100 and the second greenhouse 200 are connected to form a large temperature-controlled space. The third target temperature is the target temperature of this large space. By calculating the difference between the real-time temperature of the two greenhouses and the third target temperature, the temperature of the entire space can be controlled more accurately.

[0056] Specifically, the temperature control method of the present application first calculates the difference between the real-time temperature 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 and the third target temperature, and the fourth difference is the difference between the real-time temperature of the second greenhouse 200 and the third target temperature. These two differences reflect the temperature distribution of the entire space.

[0057] By adopting the above technical solution, by obtaining the temperature of the two greenhouses, the temperature distribution of the entire space can be better reflected, avoiding the situation where the temperature in some areas is too low or too high. At the same time, by stopping the transportation of refrigerant in time, energy can be effectively saved and the energy efficiency of the car refrigerator can be improved.

[0058] Reference Figure 2 , Attachment Figure 3 , Attachment Figure 5 The present invention also provides a vehicle refrigerator, comprising a first greenhouse 100 and a second greenhouse 200, wherein the first greenhouse 100 is surrounded by a first evaporator 110 for transporting a refrigerant, and the input end of the first evaporator 110 is connected to a first capillary tube 120, and the second greenhouse 200 is surrounded by a second evaporator 210 for transporting a refrigerant, and the input end of the second evaporator 210 is simultaneously connected to the output end of the first evaporator 110 and the second capillary tube 230 through a connecting tee 220, and the vehicle refrigerator further comprises: A temperature acquisition module 410 is used to acquire the real-time temperatures of the first greenhouse 100 and the second greenhouse 200; A first calculation module 420, configured to calculate a first difference between the real-time temperature of the first greenhouse 100 and the target temperature of the first greenhouse 100; A second calculation module 430, for calculating a second difference between the real-time temperature of the second greenhouse 200 and the target temperature of the second greenhouse 200; The refrigeration control module 440 is used to control the second capillary tube 230 to transport the refrigerant to the second evaporator 210 to cool the second greenhouse 200 alone when the first difference and the second difference both rise to positive values; and to control the first capillary tube 120 to transport the refrigerant to the first evaporator 110 to cool the first greenhouse 100 and keep the second greenhouse 200 warm when the second difference decreases from a positive value to a negative value.

[0059] By adopting the above technical solution, by obtaining the real-time temperatures of the two greenhouses and calculating the difference with the target temperature, when the first difference and the second difference both rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are both higher than the target temperature, and the second greenhouse 200 with a lower temperature requirement is refrigerated first. When the real-time temperature of the second greenhouse 200 reaches the target temperature, the first greenhouse 100 is refrigerated again, and the second greenhouse 200 is kept warm by using the residual cold of the first evaporator 110. Since the target temperature of the second greenhouse 200 is lower, the refrigeration frequency of the second greenhouse 200 is usually higher than that of the first greenhouse 100. Through the flexible flow of the refrigerant 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 to achieve coordinated refrigeration of the first greenhouse 100 and the second greenhouse 200, which helps to reduce the refrigeration frequency of the second greenhouse 200, thereby reducing the number of starts and stops of the compressor and reducing energy consumption.

[0060] In one embodiment, a middle partition plate 300 is further included. The middle partition plate 300 is detachably disposed between the first greenhouse 100 and the second greenhouse 200 . The middle partition plate 300 can separate or connect the first greenhouse 100 and the second greenhouse 200 .

[0061] By adopting the above technical solution, the temperature control method of the vehicle refrigerator of the present application can effectively solve the problem of insufficient flexibility in the use of traditional vehicle refrigerators. It can not only meet the diverse needs of users in different scenarios, but also improve energy utilization efficiency through intelligent temperature control. Compared with traditional vehicle refrigerators with fixed partitions, the method of the present application has obvious advantages in space utilization and temperature control. For example, when the user needs to store large food, the middle partition 300 can be removed to obtain a larger storage space; and when different types of food need to be stored at the same time, it can be quickly switched to 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 and reduces unnecessary energy waste.

[0062] In one embodiment, a magnetically controlled 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 magnetically controlled switch 310 adjusts the vehicle refrigerator from a single-temperature cooling mode to a dual-temperature cooling module.

[0063] By adopting the above technical solution, the magnetic control switch 310 is arranged between the first greenhouse 100 and the second greenhouse 200, so as to realize the automatic switching of the working mode of the vehicle refrigerator. When the middle partition 300 is inserted between the first greenhouse 100 and the second greenhouse 200, the magnetic control switch 310 can sense the existence of the middle partition 300, thereby automatically switching the working mode of the vehicle refrigerator from the single-temperature cooling mode to the dual-temperature cooling mode. This design not only simplifies the user operation, but also improves the intelligence level of the vehicle refrigerator.

[0064] In one embodiment, the temperature acquisition module 410 is also used to obtain the ambient temperature of the vehicle refrigerator; the refrigeration control module 440 is also used to control the first capillary 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 the ambient temperature, so as to cool the first greenhouse 100 and the second greenhouse 200 at the same time; when the first difference decreases from a negative value, control the second capillary 230 to transport refrigerant to the second evaporator 210 to cool the second greenhouse 200 alone.

[0065] In one embodiment, the vehicle refrigerator further includes an insertion acquisition module and a mode adjustment module. The insertion acquisition module is used to obtain the insertion information of the middle partition 300; the mode adjustment module is used to adjust the operation mode of the vehicle refrigerator based on the insertion information. The operation modes include a dual-temperature refrigeration mode and a single-temperature refrigeration mode.

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 mechanisms (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 obtaining the real-time temperatures of the two greenhouses and calculating the difference with the target temperature, when the first difference and the second difference both rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are both higher than the target temperature, and the second greenhouse 200 with 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 again, and the second greenhouse 200 is kept warm by using the residual cold of the first evaporator 110. Since 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. Through the flexible flow of refrigerant 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 to achieve coordinated cooling of the first greenhouse 100 and the second greenhouse 200, which helps to reduce the cooling frequency of the second greenhouse 200, thereby reducing the start and stop times of the compressor and reducing energy consumption.

[0067] An embodiment of the present application provides a storage medium having a computer program stored thereon. When the computer program is executed by a processor, the method in any optional implementation of the above embodiment is executed to achieve the following functions: by obtaining the real-time temperatures of the two greenhouses and calculating the difference with the target temperature, when the first difference and the second difference both rise to positive values, the real-time temperatures of the first greenhouse 100 and the second greenhouse 200 are both higher than the target temperature, and the second greenhouse 200 with a lower temperature requirement is cooled preferentially. When the real-time temperature of the second greenhouse 200 reaches the target temperature, the first greenhouse 100 is cooled again, and at the same time, the second greenhouse 200 is kept warm by using the residual cooling of the first evaporator 110. Since 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. Through the flexible flow of refrigerant 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 to achieve coordinated cooling of the first greenhouse 100 and the second greenhouse 200, which helps to reduce the cooling frequency of the second greenhouse 200, thereby reducing the start and stop times of the compressor and reducing energy consumption.
