Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a method, device, electronic device and medium for the linkage control of a vehicle refrigerator and an air conditioner. Background Technology

[0002] Currently, in-vehicle refrigerators face several technical challenges in practical applications that are highly dependent on ambient temperature, severely impacting their cooling performance and user experience. Firstly, in summer or under intense sunlight, the air temperature inside the vehicle rises significantly. Refrigerators using fan cooling cannot effectively cool the condenser due to the high-temperature air blown out by the fan, resulting in poor cooling and long cooling times. While compressor-cooled refrigerators have stronger cooling capacity, insufficient space for heat dissipation when the vehicle is parked and exposed to direct sunlight makes it difficult to maintain a stable low temperature inside the refrigerator. Semiconductor-cooled refrigerators are even more limited by ambient temperature, only achieving refrigeration in high summer temperatures, with further reduction in effectiveness. Secondly, in-vehicle air conditioning and refrigerators are often independent systems without coordinated operation. When a refrigerator starts in a high-temperature environment, it cannot utilize the air conditioning to lower the ambient temperature beforehand to optimize its own heat dissipation. This not only exacerbates the low cooling efficiency of the refrigerator but also leads to redundant energy consumption due to independent operation. Furthermore, existing in-vehicle refrigerators lack dynamic power adjustment based on ambient temperature and air conditioning status after startup, further affecting the stability of the cooling effect. In addition, the redundant design of independent systems indirectly increases the space occupied inside the vehicle, failing to fully leverage the synergistic effect between the two systems, resulting in a poor user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide a method, device, electronic device and medium for the linkage control of vehicle refrigerator and air conditioner in order to solve at least one of the problems existing in the prior art.

[0004] Firstly, a method for linking and controlling a vehicle-mounted refrigerator and air conditioner is provided, including: In response to the start command for the vehicle refrigerator, the current ambient temperature is detected; If the current ambient temperature is higher than a preset temperature threshold, the air conditioner will be activated to cool the temperature. When the ambient temperature drops to the vehicle refrigerator's activation trigger temperature, or when the air conditioner's activation time reaches a preset duration, the vehicle refrigerator is activated, and its cooling power is dynamically adjusted.

[0005] In one possible implementation, the vehicle refrigerator and the air conditioner share the same refrigeration module. After the vehicle refrigerator is started, the weight information of the items inside the vehicle refrigerator and the real-time temperature of the air conditioner vent are obtained. Based on the weight information of the items and the real-time temperature, the refrigerant flow rate delivered by the refrigeration module to the vehicle refrigerator is adjusted to dynamically adapt to the refrigeration needs of the vehicle refrigerator.

[0006] In one possible implementation, the method further includes: If the current environment is low temperature, obtain the waste heat emitted when the high temperature and high pressure refrigerant formed by the compressor in the air conditioner flows through the condenser; The waste heat emitted by the condenser is transferred to the heat transfer medium, which is water or antifreeze, through a pre-set heat exchange device. The heat transfer medium carrying waste heat is controlled to be delivered to the internal heating components of the vehicle refrigerator through a pre-set pipeline; The waste heat carried by the heat transfer medium is used to heat the interior of the vehicle refrigerator through the internal heating component to meet the heating requirements of the vehicle refrigerator in low-temperature environments.

[0007] In one possible implementation, the method further includes: When the vehicle refrigerator is in operation, the condensation heat released by the condenser of the vehicle refrigerator during the refrigerant heat release process is obtained; The system checks whether the preheating trigger conditions of the vehicle air conditioner are met. The preheating trigger conditions include the ambient temperature being lower than a preset temperature threshold or before the air conditioner is turned on. If the preheating trigger condition is met, the corresponding valve in the preset switchable heat exchange circuit is opened, and the condensing heat released by the condenser of the vehicle refrigerator is guided to the air passage of the vehicle air conditioner through the heat exchange circuit. The condensation heat is used to preheat the air entering the air conditioning air passage, thereby shortening the time it takes for the air conditioner to reach the set temperature and reducing the energy consumption of the air conditioner.

[0008] In one possible implementation, the method further includes: Real-time monitoring of the current voltage of the battery supplying power to the vehicle-mounted refrigerator; If the current voltage is lower than a first preset threshold and higher than a second preset threshold, the cooling power of the vehicle refrigerator will be automatically reduced. If the current voltage is lower than or equal to the second preset threshold, the vehicle refrigerator is controlled to stop operating, wherein the second preset threshold is the minimum safe voltage to ensure that the vehicle can start normally; The first preset threshold is higher than the second preset threshold, and the first preset threshold and the second preset threshold are set according to the battery type.

[0009] In one possible implementation, activating the vehicle-mounted refrigerator and dynamically adjusting its cooling power includes: During the startup process of the vehicle refrigerator, the current temperature of the vehicle refrigerator and the type of items placed inside are detected; If the placed item is perishable and the current temperature is higher than the preservation threshold, start the vehicle refrigerator and adjust the cooling temperature of the vehicle refrigerator to be lower than the preset cooling temperature threshold. If the item being placed is a durable product and the current temperature is less than or equal to the preservation threshold, start the vehicle refrigerator and maintain basic cooling power.

[0010] In one possible implementation, the dynamic adjustment of the cooling power of the vehicle-mounted refrigerator includes: Detect the first current cooling load of the air conditioner and the second current cooling load of the vehicle refrigerator; If the first current cooling load is less than the first preset threshold and the second current cooling load is greater than the second preset threshold, increase the refrigerant flow in the vehicle refrigerator cooling pipe while maintaining basic air conditioning cooling. If the first current cooling load is greater than the third preset threshold and the second current cooling load is less than the fourth preset threshold, then reduce the refrigerant flow rate of the vehicle refrigerator's cooling pipes.

[0011] Secondly, a vehicle-mounted refrigerator and air conditioning linkage control device is provided, including: The current ambient temperature detection unit is used to detect the current ambient temperature in response to the start command for the vehicle refrigerator; An air conditioning start-up unit is used to start the air conditioner to cool down the environment if the current ambient temperature is higher than a preset temperature threshold. The vehicle refrigerator start-up unit is used to start the vehicle refrigerator when the ambient temperature drops to the vehicle refrigerator start-up trigger temperature, or when the air conditioner starts for a preset time, and to dynamically adjust the cooling power of the vehicle refrigerator.

[0012] Thirdly, an electronic device is provided, including a memory, a processor, and computer-readable instructions stored in the memory and executable on the processor, wherein the processor, when executing the computer-readable instructions, implements the steps of the vehicle refrigerator and air conditioner linkage control method described above.

[0013] Fourthly, a readable storage medium is provided, which stores computer-readable instructions that, when executed by a processor, implement the steps of the vehicle refrigerator and air conditioner linkage control method described above.

[0014] The aforementioned method, device, electronic equipment, and medium for the coordinated control of a vehicle refrigerator and air conditioner include the following steps: responding to a start command for the vehicle refrigerator, detecting the current ambient temperature; if the current ambient temperature is higher than a preset temperature threshold, starting the air conditioner for cooling; when the ambient temperature drops to the vehicle refrigerator start trigger temperature, or the air conditioner has been running for a preset duration, starting the vehicle refrigerator and dynamically adjusting its cooling power. This technical solution, through the coordinated control of the air conditioner and vehicle refrigerator, responds to the start command of the vehicle refrigerator in a high-temperature environment by first starting the air conditioner for cooling, and then starting the vehicle refrigerator only after the ambient temperature reaches the target or the air conditioner has run for a preset duration. This effectively avoids the problem of high temperatures affecting the heat dissipation of the vehicle refrigerator, significantly improves cooling efficiency, shortens cooling time, and ensures the temperature stability of the compressor-cooled vehicle refrigerator when it is not in use. Simultaneously, it breaks the limitation of independent operation between the two, reduces redundant energy consumption, and dynamically adjusts the cooling power after the vehicle refrigerator starts, further ensuring stable cooling effect. It does not require additional complex structures, improving performance while considering the space occupied in the vehicle and optimizing the user experience. Attached Figure Description

[0015] To more clearly illustrate the technical solutions of the embodiments of this application, the drawings used in the description of the embodiments of this application will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Figure 1 This is a flowchart illustrating a method for the linkage control of a vehicle refrigerator and an air conditioner in one embodiment of this application; Figure 2 This is a schematic diagram of the structure of a vehicle refrigerator and air conditioner linkage control device in one embodiment of this application; Figure 3 This is a schematic diagram of an electronic device according to an embodiment of this application. Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] In one embodiment, such as Figure 1 As shown, a method for linking and controlling a vehicle refrigerator and an air conditioner is provided, including the following steps: In step S110, in response to the start command for the vehicle refrigerator, the current ambient temperature is detected; Optionally, when a user issues a start command for the car refrigerator via a physical button, in-vehicle central control unit, or mobile terminal, an ambient temperature detection process is triggered. This process uses temperature sensors pre-installed in appropriate locations within the car refrigerator or vehicle to collect real-time ambient temperature data around the refrigerator and inside the vehicle. The cooling performance of the car refrigerator (such as heat dissipation efficiency, cooling speed, and power consumption) is strongly correlated with ambient temperature. High temperatures directly hinder heat dissipation from the refrigerator's condenser, reducing cooling efficiency. By checking the current ambient temperature, it can be ensured that the car refrigerator operates under suitable environmental conditions after startup.

[0019] In step S120, if the current ambient temperature is higher than a preset temperature threshold, the air conditioner is activated to cool down the room. Optionally, after detecting the current ambient temperature, the measured temperature is compared with a preset temperature threshold. When the current ambient temperature is determined to be higher than the threshold, the vehicle's air conditioning is activated, switching it into cooling mode. By activating the air conditioning in advance, the overall temperature inside the vehicle and around the refrigerator can be quickly reduced, eliminating the adverse effects of high temperatures on the refrigerator's heat dissipation and preventing excessive energy consumption and component load caused by forcibly starting the refrigerator in a high-temperature environment. The preset temperature threshold can be set based on the ambient temperature requirements for efficient refrigerator operation, such as 30°C. Below this temperature, the refrigerator's heat dissipation efficiency can meet basic cooling needs; above this temperature, heat dissipation may be hindered.

[0020] In step S130, when the ambient temperature drops to the vehicle refrigerator start-up trigger temperature, or the air conditioner start-up time reaches the preset time, the vehicle refrigerator is started, and the cooling power of the vehicle refrigerator is dynamically adjusted.

[0021] Optionally, during air conditioning operation, the ambient temperature can be monitored in real time. When the ambient temperature drops to the vehicle refrigerator's activation trigger temperature (e.g., 26°C, which is the ideal ambient temperature for efficient cooling and heat dissipation), it indicates that the vehicle refrigerator has met the activation conditions and can be started immediately. In addition, if the ambient temperature does not reach the trigger temperature for a long time due to extreme high temperatures (e.g., a sudden rise in interior temperature after being exposed to the sun and difficult to lower), the vehicle refrigerator will also be triggered to start when the air conditioning starts for a preset time (e.g., 5-8 minutes, which can be set based on the air conditioning's normal cooling efficiency and the vehicle refrigerator's weather resistance, avoiding excessive power consumption by the air conditioning while ensuring that the ambient temperature has dropped to an acceptable range for the vehicle refrigerator). This avoids the problem of users being unable to use the vehicle refrigerator for a long time due to a single temperature condition causing the refrigerator to be stuck.

[0022] When the car refrigerator is started, the compressor frequency or semiconductor cooling power can be flexibly adjusted based on the current ambient temperature (e.g., whether it is close to the trigger temperature), the real-time operating status of the air conditioner (e.g., whether it is still in high-intensity cooling), the temperature of the air conditioner vents, and the type, weight, and internal temperature of the items in the car refrigerator. For example, when the ambient temperature is slightly higher than the trigger temperature, the power can be appropriately increased to quickly compensate for cooling; when the ambient temperature is stable and meets the standard, the base power can be maintained to save energy. Ultimately, this achieves precise and controllable start-up timing and dynamic adaptation of the operating status of the car refrigerator, solving the problems of difficult start-up and poor cooling at high temperatures, while avoiding redundant energy consumption.

[0023] It should be noted that the system can also acquire the vehicle's current operating status. If the vehicle is in motion, and the ambient temperature is stable below the refrigerator's start-up trigger temperature and the air conditioning load is low, it will maintain basic power operation. If the ambient temperature shows a rising trend or the items in the refrigerator are perishable, the power can be appropriately increased to quickly suppress temperature fluctuations and ensure cooling effect. In this case, there is no need to strictly limit the power limit; the priority is to meet the preservation needs. If the vehicle is off, the refrigerator relies on the vehicle's battery for power, and its energy sustainability is limited. After starting, it will default to a low-power mode. It can also dynamically adapt based on the remaining battery power. If the battery is sufficient, it can maintain the current low power. If the battery is low, it will further reduce the power to the cooling setting (only maintaining the internal temperature from rising significantly). The system can also remind the user through the vehicle's onboard system to avoid the refrigerator continuously consuming power and causing the battery to deplete, affecting vehicle startup.

[0024] In one embodiment of this application, the vehicle refrigerator and the air conditioner share the same refrigeration module. After the vehicle refrigerator is started, the weight information of the items inside the vehicle refrigerator and the real-time temperature of the air conditioner vent are obtained. Based on the weight information and the real-time temperature, the refrigerant flow rate delivered by the refrigeration module to the vehicle refrigerator is adjusted to dynamically adapt to the refrigeration needs of the vehicle refrigerator. Specifically, the air conditioner and the vehicle refrigerator share the same refrigeration module (such as core components like compressors and condensers), simplifying the structure and avoiding energy redundancy. After the vehicle refrigerator is started, the weight of the items and the temperature of the air conditioner vent are used as dual bases for adjusting the refrigerant flow rate: the weight of the items directly reflects the current refrigeration load of the vehicle refrigerator (e.g., more cooling capacity is needed to maintain a low temperature when fully loaded, while less cooling capacity can be used to avoid waste when lightly loaded); the temperature of the air conditioner vent indirectly reflects the overall load of the current refrigeration module and its environmental adaptability (e.g., a low vent temperature indicates sufficient module cooling capacity, and refrigerant can be appropriately allocated to the vehicle refrigerator; a high temperature requires balanced distribution to avoid affecting the core function of the air conditioner).

[0025] Through the coordinated analysis of these two parameters, the refrigerant flow to the vehicle refrigerator can be dynamically adjusted (e.g., via an electronic expansion valve or four-way valve assembly): when the items are heavy and the air conditioning load is low, the refrigerant flow is increased to enhance the vehicle refrigerator's cooling; when the items are light or the air conditioning needs to be prioritized, the refrigerant flow is reduced to save energy. This precise parameter sensing enables on-demand allocation, ultimately ensuring the vehicle refrigerator's cooling effect while improving the overall energy efficiency of the refrigeration system, balancing structural simplification and performance optimization.

[0026] This application provides a method for coordinated control of a vehicle refrigerator and an air conditioner, comprising: responding to a start command for the vehicle refrigerator and detecting the current ambient temperature; if the current ambient temperature is higher than a preset temperature threshold, starting the air conditioner for cooling; when the ambient temperature drops to the vehicle refrigerator start trigger temperature, or the air conditioner has been running for a preset duration, starting the vehicle refrigerator and dynamically adjusting the cooling power of the vehicle refrigerator. This technical solution, through coordinated control of the air conditioner and the vehicle refrigerator, responds to the start command of the vehicle refrigerator in a high-temperature environment by first starting the air conditioner for cooling, and then starting the vehicle refrigerator after the ambient temperature reaches the target or the air conditioner has run for a preset duration. This effectively avoids the problem of high temperatures affecting the heat dissipation of the vehicle refrigerator, significantly improves cooling efficiency, shortens cooling time, and ensures the temperature stability of the vehicle refrigerator when the compressor is cooling it while the vehicle is not in use. Simultaneously, it breaks the limitation of independent operation of the two, reduces redundant energy consumption, and the dynamic adjustment of cooling power after the vehicle refrigerator starts further ensures stable cooling effect. It does not require additional complex structures, improving performance while considering the space occupied in the vehicle and optimizing the user experience.

[0027] In one embodiment of this application, the method further includes: If the current environment is low temperature, obtain the waste heat emitted when the high temperature and high pressure refrigerant formed by the compressor in the air conditioner flows through the condenser; The waste heat emitted by the condenser is transferred to the heat transfer medium, which is water or antifreeze, through a pre-set heat exchange device. The heat transfer medium carrying waste heat is controlled to be delivered to the internal heating components of the vehicle refrigerator through a pre-set pipeline; The waste heat carried by the heat transfer medium is used to heat the interior of the vehicle refrigerator through the internal heating component to meet the heating requirements of the vehicle refrigerator in low-temperature environments.

[0028] Optionally, if the current environment is low temperature (such as winter), the air conditioning compressor will compress the refrigerant to form a high temperature and high pressure refrigerant. When this type of refrigerant flows through the condenser, it will release a large amount of heat (i.e., the waste heat that is directly discarded in traditional scenarios). Through a preset heat exchange device (such as a heat exchanger), this part of the waste heat emitted by the condenser is efficiently transferred to a heat transfer medium such as water or antifreeze. Then, through a specially designed pipeline system, the heat transfer medium carrying the waste heat is transported to the internal heating component of the vehicle refrigerator. Finally, the heating component uses the waste heat carried by the heat transfer medium to heat the inside of the vehicle refrigerator. This not only meets the heating needs of the vehicle refrigerator in low temperature environments, but also avoids the energy consumption caused by the vehicle refrigerator relying on an independent electric heating module for heating. At the same time, it does not affect the normal cooling function of the air conditioner. It is especially suitable for the complex scenario in winter where the vehicle interior needs to meet both cooling and vehicle refrigerator insulation at the same time.

[0029] In one embodiment of this application, the method further includes: When the vehicle refrigerator is in operation, the condensation heat released by the condenser of the vehicle refrigerator during the refrigerant heat release process is obtained; The system checks whether the preheating trigger conditions of the vehicle air conditioner are met. The preheating trigger conditions include the ambient temperature being lower than a preset temperature threshold or before the air conditioner is turned on. If the preheating trigger condition is met, the corresponding valve in the preset switchable heat exchange circuit is opened, and the condensing heat released by the condenser of the vehicle refrigerator is guided to the air passage of the vehicle air conditioner through the heat exchange circuit. The condensation heat is used to preheat the air entering the air conditioning air passage, thereby shortening the time it takes for the air conditioner to reach the set temperature and reducing the energy consumption of the air conditioner.

[0030] Optionally, when the vehicle refrigerator is in cooling mode, its condenser will continuously release condensation heat during the refrigerant heat release process (in traditional scenarios, this heat is often directly wasted). The system can detect in real time whether the preheating trigger conditions of the vehicle air conditioner are met, including when the ambient temperature is lower than the preset temperature threshold (such as in low-temperature environments in winter, where direct heating by the air conditioner requires a lot of energy) or before the air conditioner is turned on (preheating the air conditioner in advance to improve the heating speed after startup). If the trigger conditions are met, the corresponding valve in the preset switchable heat exchange circuit can be opened, and the condensation heat released by the vehicle refrigerator condenser can be directed to the air passage of the vehicle air conditioner through this circuit. Finally, this part of the condensation heat is used to preheat the air entering the air passage of the air conditioner, so that the air conditioner does not need to start heating from zero when it starts heating. This can significantly shorten the time it takes for the air conditioner to reach the set temperature, improve the user's comfort, reduce the energy consumption during the air conditioner heating process, and at the same time, it does not affect the normal cooling function of the vehicle refrigerator.

[0031] In one embodiment of this application, the method further includes: Real-time monitoring of the current voltage of the battery supplying power to the vehicle-mounted refrigerator; If the current voltage is lower than a first preset threshold and higher than a second preset threshold, the cooling power of the vehicle refrigerator will be automatically reduced. If the current voltage is lower than or equal to the second preset threshold, the vehicle refrigerator is controlled to stop operating, wherein the second preset threshold is the minimum safe voltage to ensure that the vehicle can start normally; The first preset threshold is higher than the second preset threshold, and the first preset threshold and the second preset threshold are set according to the battery type.

[0032] Optionally, during the operation of the in-vehicle refrigerator or air conditioner, the current battery voltage can be monitored in real time. This current battery voltage can be the current voltage of the vehicle's main battery or the current voltage of the secondary battery, where the secondary battery refers to the battery in the car used to power in-vehicle electrical equipment such as the in-vehicle refrigerator. Simultaneously, two differentiated protection thresholds are preset based on the battery type (e.g., lead-acid battery, lithium battery), with the first preset threshold being higher than the second preset threshold. When the detected current battery voltage is lower than the first preset threshold but still higher than the second preset threshold, it indicates that the battery power is insufficient but has not reached a critical state. At this time, the cooling power of the in-vehicle refrigerator is automatically reduced (e.g., reducing compressor frequency, reducing semiconductor cooling intensity). While reducing battery power consumption, the basic cooling function of the in-vehicle refrigerator is preserved as much as possible to prevent a sudden rise in the temperature of items inside. When the voltage further drops below or equal to the second preset threshold (this threshold is set as the minimum safe voltage to ensure normal vehicle startup, such as approximately 11.1V for lead-acid batteries), it indicates that the battery is approaching the critical depletion value. The in-vehicle refrigerator must be immediately shut down, with only the low-power monitoring module remaining operational to prioritize vehicle power supply and avoid the risk of the vehicle failing to start or battery damage due to continuous power consumption by the in-vehicle refrigerator.

[0033] In one embodiment of this application, the step of activating the vehicle-mounted refrigerator and dynamically adjusting its cooling power includes: During the startup process of the vehicle refrigerator, the current temperature of the vehicle refrigerator and the type of items placed inside are detected; If the placed item is perishable and the current temperature is higher than the preservation threshold, start the vehicle refrigerator and adjust the cooling temperature of the vehicle refrigerator to be lower than the preset cooling temperature threshold. If the item being placed is a durable product and the current temperature is less than or equal to the preservation threshold, start the vehicle refrigerator and maintain basic cooling power.

[0034] Optionally, upon responding to the vehicle refrigerator start command, the current temperature of the vehicle refrigerator can be obtained through the detection module. At the same time, the type of items placed inside the refrigerator can be obtained through user presets or image recognition. If it is determined that the placed items are perishable (such as fresh food, cooked food, etc., which are temperature-sensitive and require strict temperature control), and the current temperature of the vehicle refrigerator is higher than the preservation threshold of such items, it indicates that the items are at risk of spoilage. At this time, the vehicle refrigerator is started and the cooling temperature is adjusted to a level lower than the preset cooling temperature threshold (such as 3-5℃ lower than the preservation threshold). By quickly reducing the temperature inside the refrigerator, the freshness of perishable items is ensured. If it is determined that the placed items are durable (such as bottled beverages, dry goods, etc., which are highly tolerant of temperature fluctuations), and the current temperature of the vehicle refrigerator is less than or equal to the preservation threshold, it indicates that the items are currently in a safe storage state. At this time, after starting the vehicle refrigerator, only the basic cooling power is maintained, ensuring the basic preservation needs of the items while avoiding unnecessary energy consumption.

[0035] In one embodiment of this application, the dynamic adjustment of the cooling power of the vehicle-mounted refrigerator includes: Detect the first current cooling load of the air conditioner and the second current cooling load of the vehicle refrigerator; If the first current cooling load is less than the first preset threshold and the second current cooling load is greater than the second preset threshold, increase the refrigerant flow in the vehicle refrigerator cooling pipe while maintaining basic air conditioning cooling. If the first current cooling load is greater than the third preset threshold and the second current cooling load is less than the fourth preset threshold, then reduce the refrigerant flow rate of the vehicle refrigerator's cooling pipes.

[0036] Optionally, when both the air conditioner and the car refrigerator are running, the first current cooling load of the air conditioner (such as temperature difference reflecting the cooling demand inside the vehicle, compressor operating frequency, etc.) and the second current cooling load of the car refrigerator (such as temperature difference reflecting the cooling demand inside the car refrigerator, heat capacity of items, etc.) can be detected simultaneously. If the first current cooling load of the air conditioner is less than the first preset threshold (indicating low air conditioner load) and the second current cooling load of the car refrigerator is greater than the second preset threshold (indicating high car refrigerator load and need for enhanced cooling), the refrigerant flow in the car refrigerator's cooling pipe can be increased to provide more cooling support for the car refrigerator, while maintaining the basic cooling state of the air conditioner to prevent the temperature inside the vehicle from rising again; if the first current cooling load of the air conditioner is greater than the third preset threshold (indicating high air conditioner load and need to prioritize cooling inside the vehicle), and the second current cooling load of the car refrigerator is less than the fourth preset threshold (indicating low car refrigerator load and weak cooling demand), the refrigerant flow in the car refrigerator's cooling pipe can be reduced to allocate more refrigerant resources to the air conditioner and ensure the air conditioner's cooling effect. By using dual-load linkage judgment and dynamic adjustment of refrigerant flow, the limitation of independent operation of air conditioner and vehicle refrigerator is broken, and energy efficiency can be achieved at the same time.

[0037] In this embodiment, through the coordinated control of the air conditioner and the vehicle refrigerator, the air conditioner is activated first to cool down the vehicle refrigerator in response to the start command in a high-temperature environment. The vehicle refrigerator is then activated only after the ambient temperature reaches the standard or the air conditioner has run for a preset time. This effectively avoids the problem of high temperature affecting the heat dissipation of the vehicle refrigerator, significantly improves cooling efficiency, shortens cooling time, and ensures the temperature stability of the vehicle refrigerator when the compressor is not in use. At the same time, it breaks the limitation of independent operation of the two, reduces redundant energy consumption, and dynamically adjusts the cooling power after the vehicle refrigerator is started to further ensure stable cooling effect. No additional complex structure is required, which improves performance while taking into account the space occupied in the vehicle and optimizes the user experience.

[0038] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0039] In one embodiment, a vehicle refrigerator and air conditioner linkage control device is provided, which corresponds one-to-one with the vehicle refrigerator and air conditioner linkage control method described in the above embodiments. For example... Figure 2 As shown, the vehicle refrigerator and air conditioning linkage control device includes a current ambient temperature detection unit 10, an air conditioning start unit 20, and a vehicle refrigerator start unit 30. Detailed descriptions of each functional module are as follows: The current ambient temperature detection unit 10 is used to detect the current ambient temperature in response to the start command for the vehicle refrigerator; Air conditioning start-up unit 20 is used to start the air conditioner to cool down if the current ambient temperature is higher than a preset temperature threshold. The vehicle refrigerator start-up unit 30 is used to start the vehicle refrigerator when the ambient temperature drops to the vehicle refrigerator start-up trigger temperature, or when the air conditioner starts for a preset time, and to dynamically adjust the cooling power of the vehicle refrigerator.

[0040] In one embodiment of this application, the vehicle refrigerator and the air conditioner share the same refrigeration module. After the vehicle refrigerator is started, the weight information of the items inside the vehicle refrigerator and the real-time temperature of the air conditioner outlet are obtained. Based on the weight information of the items and the real-time temperature, the flow rate of refrigerant delivered to the vehicle refrigerator by the refrigeration module is adjusted to dynamically adapt to the refrigeration needs of the vehicle refrigerator.

[0041] In one embodiment of this application, the apparatus further includes a waste heat utilization unit, used for: If the current environment is low temperature, obtain the waste heat emitted when the high temperature and high pressure refrigerant formed by the compressor in the air conditioner flows through the condenser; The waste heat emitted by the condenser is transferred to the heat transfer medium, which is water or antifreeze, through a pre-set heat exchange device. The heat transfer medium carrying waste heat is controlled to be delivered to the internal heating components of the vehicle refrigerator through a pre-set pipeline; The waste heat carried by the heat transfer medium is used to heat the interior of the vehicle refrigerator through the internal heating component to meet the heating requirements of the vehicle refrigerator in low-temperature environments.

[0042] In one embodiment of this application, the device further includes an air conditioning preheating unit, used for: When the vehicle refrigerator is in operation, the condensation heat released by the condenser of the vehicle refrigerator during the refrigerant heat release process is obtained; The system checks whether the preheating trigger conditions of the vehicle air conditioner are met. The preheating trigger conditions include the ambient temperature being lower than a preset temperature threshold or before the air conditioner is turned on. If the preheating trigger condition is met, the corresponding valve in the preset switchable heat exchange circuit is opened, and the condensing heat released by the condenser of the vehicle refrigerator is guided to the air passage of the vehicle air conditioner through the heat exchange circuit.
