Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically providing a vehicle air conditioning system control method and a vehicle. Background Technology

[0002] As people's living standards continue to improve, there is an increasing demand for vehicles with refrigeration functions. Currently, some vehicles, such as commercial vehicles, are equipped with refrigeration functions. The cooling and food refrigeration functions required by commercial vehicles are basically provided by separate devices.

[0003] Currently, the vehicle's parking air conditioning provides cooling for the interior, while food refrigeration is achieved using the original vehicle's air conditioning system. This means that food and other items cannot be kept refrigerated while the vehicle is parked. In order to meet the refrigeration function when parked, a separate refrigerator needs to be installed, which takes up space and reduces space utilization. Moreover, the refrigeration function is always on regardless of whether there is food in the refrigerator compartment, resulting in energy waste when the refrigerator is empty. If it needs to be turned off, the user needs to turn it off manually, which is inconvenient and results in a poor user experience.

[0004] Therefore, the present invention needs to provide a new vehicle air conditioning system control method and a vehicle to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention aims to solve the aforementioned technical problems, namely, that the current vehicle parking air conditioner provides cooling for the interior, while food refrigeration is achieved using the original vehicle air conditioning system. This means that food and other items cannot be refrigerated while the vehicle is parked. In order to meet the refrigeration function when parked, a separate refrigerator needs to be installed, which occupies space and reduces space utilization. Moreover, the refrigeration function is always on regardless of whether there is food in the refrigerator compartment, resulting in energy waste when the refrigerator is empty.

[0012] With the above technical solution, the vehicle air conditioning system and parking air conditioning system can select the appropriate mode based on the difference between the interior temperature and the preset temperature, as well as the presence of food in the refrigerator compartment, regardless of whether the vehicle is in motion or parked. This achieves intelligent adjustment of the cooling function in the refrigerator compartment and the vehicle interior, ensuring that user needs are not interrupted during driving and parking, and improving the user experience and the happiness of vehicle life.

Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] Currently, the vehicle's parking air conditioning provides cooling for the interior, while food refrigeration is achieved using the original vehicle's air conditioning system. This means that food and other items cannot be kept refrigerated while the vehicle is parked. In order to meet the refrigeration function when parked, a separate refrigerator needs to be installed, which takes up space and reduces space utilization. Moreover, the refrigeration function is always on regardless of whether there is food in the refrigerator compartment, resulting in energy waste when the refrigerator is empty. If it needs to be turned off, the user needs to turn it off manually, which is inconvenient and results in a poor user experience.

[0048] To address the aforementioned technical problems, this invention provides a vehicle air conditioning system. The vehicle includes a refrigerator compartment equipped with a food detector to detect the presence of food within the compartment. Exemplarily, the food detector is a weighing sensor, and the presence of food in the refrigerator compartment is detected by the weight information detected by the weighing sensor. The air conditioning system includes a driving air conditioning system 7 and a parking air conditioning system 8.

[0049] In one embodiment, see Figure 4 The air conditioning system includes a first compressor 1, a second compressor 4, a first outdoor heat exchanger 2, a second outdoor heat exchanger 3, an indoor heat exchanger 6, and a refrigerator heat exchanger 5. The first compressor 1, the first outdoor heat exchanger 2, the indoor heat exchanger 6, and the refrigerator heat exchanger 5 are combined to form a driving air conditioning system 7. The second compressor 4, the second outdoor heat exchanger 3, the indoor heat exchanger 6, and the refrigerator heat exchanger 5 are combined to form a parking air conditioning system 8.

[0050] In one embodiment, see Figure 4 The outlet end of the first outdoor heat exchanger 2 and the outlet end of the second outdoor heat exchanger 3 intersect at a junction, and a first three-way valve is installed at this junction; the inlet end of the indoor heat exchanger 6 and the inlet end of the cold storage heat exchanger 5 intersect at a junction, and a second three-way valve is installed at this junction. The first three-way valve and the second three-way valve are connected through a first pipeline, and a throttling valve is installed on the first pipeline.

[0051] Specifically, the outlet of the first compressor 1 is connected to the inlet of the first outdoor heat exchanger 2 via a second pipeline. The outlet of the first outdoor heat exchanger 2 is connected to a third pipeline, which is connected to a common pipeline. One end of the common pipeline is connected to the inlet of the indoor heat exchanger 6 and the refrigerator heat exchanger 5, respectively. The outlet of the second outdoor heat exchanger 3 is connected to a fourth pipeline, which is connected to the common pipeline. A first three-way valve is installed at the junction of the third, fourth, and common pipelines. The inlet of the indoor heat exchanger 6 is connected to a fifth pipeline, and the inlet of the refrigerator heat exchanger 5 is connected to a sixth pipeline. A second three-way valve is installed at the junction of the common pipeline and the fifth and sixth pipelines. The outlets of the indoor heat exchanger 6 and the refrigerator heat exchanger 5 are both connected to the inlet of the first compressor 1 and the inlet of the second compressor 4 via a seventh pipeline, respectively. The outlet of the second compressor 4 is connected to the inlet of the second outdoor heat exchanger 3.

[0052] In addition, the air conditioning system also includes a fan 9. The fan 9 is installed in the first outdoor heat exchanger 2, the second indoor heat exchanger 6, the indoor heat exchanger 6 and the cold storage room. The fan 9 is used to realize air flow for heat exchange.

[0053] It should be noted that although the food detector described above is a weighing sensor, this is only an example. It can also be a pressure sensor, which is also within the scope of protection of this invention.

[0054] In the above embodiment, the automatic switching between the driving air conditioning system 7 and the parking air conditioning system 8 is realized by opening and closing the various passages of the first three-way valve and the second three-way valve. The degree of automation is high, which is conducive to improving the user experience. Moreover, the driving air conditioning system 7 and the parking air conditioning system 8 share some pipelines, reducing the amount of pipeline used and reducing space occupation.

[0055] First refer to Figure 1 The present invention also provides a vehicle air conditioning system control method, the air conditioning system control method comprising:

[0056] S1, determine if the vehicle is running;

[0057] S2, compares the interior temperature with the preset temperature;

[0058] S3, determine if there is food in the refrigerator compartment;

[0059] S4, if the vehicle is running, based on the difference between the interior temperature and the preset temperature and the determination of whether there is food in the refrigerator compartment, selectively control the vehicle air conditioning system 7 to execute one of the following modes: single air cooling mode, single refrigerator cooling mode, dual air cooling and refrigerator cooling mode, and off mode.

[0060] S5, if the vehicle is in a parked state, based on the difference between the interior temperature and the preset temperature and the determination of whether there is food in the refrigerator compartment, the parking air conditioning system 8 is selectively controlled to perform one of the following modes: single air cooling mode, single refrigerator cooling mode, air cooling and refrigerator cooling dual-on mode, and off mode.

[0061] It should be noted that the specific value of the preset temperature is not specifically limited in this application, and can be flexibly designed according to different user needs, such as a preset temperature of 30°.

[0062] Furthermore, regarding the execution order of steps S1, S2, and S3, it should be noted that although this application describes executing S1 first, followed by S2 and S3 in sequence, this is merely an example. Without departing from the basic principles of this invention, those skilled in the art can arbitrarily adjust the execution order of S1, S2, and S3 as needed. For example, S2 can be executed first, followed by S1 and S3, or all three can be executed simultaneously. The adjusted solution is equivalent to the technical solution described in this application and therefore will also fall within the protection scope of this invention.

[0063] In one embodiment, the single-air cooling mode corresponding to the vehicle air conditioning system 7 is as follows: the passage connecting the first three-way valve to the outlet end of the second outdoor heat exchanger 3 is closed, the passage connecting the first three-way valve to the outlet end of the first outdoor heat exchanger 2 is opened, and the passage connecting the second three-way valve to the inlet end of the refrigerator compartment heat exchanger 5 is closed at the same time.

[0064] In one embodiment, the single-air cooling mode corresponding to the parking air conditioning system 8 is as follows: open the passage connecting the first three-way valve to the outlet end of the second outdoor heat exchanger 3, close the passage connecting the first three-way valve to the outlet end of the first outdoor heat exchanger 2, and simultaneously close the passage connecting the second three-way valve to the inlet end of the refrigerator compartment heat exchanger 5.

[0065] In one embodiment, the single refrigeration mode corresponding to the vehicle air conditioning system 7 is as follows: the passage connecting the first three-way valve to the outlet end of the second outdoor heat exchanger 3 is closed, the passage connecting the first three-way valve to the outlet end of the first outdoor heat exchanger 2 is opened, and the passage connecting the second three-way valve to the inlet end of the indoor heat exchanger 6 is closed at the same time.

[0066] In one embodiment, the single refrigeration mode corresponding to the parking air conditioning system 8 is as follows: open the passage connecting the first three-way valve to the outlet end of the second outdoor heat exchanger 3, close the passage connecting the first three-way valve to the outlet end of the first outdoor heat exchanger 2, and simultaneously close the passage connecting the second three-way valve to the inlet end of the indoor heat exchanger 6.

[0067] In one embodiment, the dual-mode air refrigeration and cooling corresponding to the vehicle air conditioning system 7 is as follows: the passage connecting the first three-way valve to the outlet of the second outdoor heat exchanger 3 is opened, the passage connecting the first three-way valve to the outlet of the first outdoor heat exchanger 2 is closed, and the passage connecting the second three-way valve to the inlet of the refrigeration compartment heat exchanger 5 and the inlet of the indoor heat exchanger 6 are both in the open state.

[0068] In one embodiment, the dual-mode air refrigeration and cooling corresponding to the parking air conditioning system 8 is as follows: the passage connecting the first three-way valve to the outlet of the second outdoor heat exchanger 3 is closed, the passage connecting the first three-way valve to the outlet of the first outdoor heat exchanger 2 is opened, and at the same time, the passage connecting the second three-way valve to the inlet of the refrigeration compartment heat exchanger 5 and the inlet of the indoor heat exchanger 6 are both in the open state.

[0069] In one embodiment, see Figure 2 The step S4, which involves "selectively controlling the vehicle's air conditioning system 7 to perform one of the following modes based on the difference between the vehicle's interior temperature and the preset temperature, as well as the presence of food in the refrigerator compartment," specifically includes:

[0070] S41, if the interior temperature is higher than the preset temperature and there is no food in the refrigerator compartment, control the vehicle air conditioning system 7 to execute the single-air cooling mode.

[0071] In the above steps, if there is no food in the refrigerator compartment, that is, no refrigeration function is needed, and the temperature inside the vehicle is higher than the preset temperature, it is sufficient to turn on the single air cooling mode, which helps to save energy.

[0072] S42, if the interior temperature is lower than the preset temperature and there is no food in the refrigerator compartment, control the vehicle air conditioning system 7 to enter the off mode;

[0073] S43, if the interior temperature is higher than the preset temperature and there is food in the refrigerator compartment, control the vehicle air conditioning system 7 to execute the dual-mode of air refrigeration and cooling.

[0074] S44, if the interior temperature is lower than the preset temperature and there is food in the refrigerator compartment, control the vehicle air conditioning system 7 to execute the single refrigerator cooling mode.

[0075] In the above steps, if there is food in the refrigerator compartment, the refrigeration function is needed. If the temperature inside the vehicle is lower than the preset temperature, you only need to turn on the single refrigeration mode, which helps to save energy.

[0076] In one embodiment, see Figure 3The step S5, which involves "selectively controlling the parking air conditioning system 8 to perform one of the following modes based on the difference between the vehicle interior temperature and the preset temperature, and the determination of whether there is food in the refrigerator compartment," specifically includes:

[0077] S51, if the interior temperature is higher than the preset temperature and there is no food in the refrigerator compartment, control the parking air conditioning system 8 to execute the single air cooling mode.

[0078] In the above steps, if there is no food in the refrigerator compartment, that is, no refrigeration function is needed, and the temperature inside the vehicle is higher than the preset temperature, it is sufficient to turn on the single air cooling mode, which helps to save energy.

[0079] S52, if the interior temperature is lower than the preset temperature and there is no food in the refrigerator compartment, control the parking air conditioning system 8 to enter the off mode;

[0080] S53, if the interior temperature is higher than the preset temperature and there is food in the refrigerator compartment, control the parking air conditioning system 8 to execute the dual-mode of air refrigeration and cooling.

[0081] S54, if the interior temperature is lower than the preset temperature and there is food in the refrigerator compartment, control the parking air conditioning system 8 to execute the single refrigerator cooling mode.

[0082] In the above steps, if there is food in the refrigerator compartment, the refrigeration function is needed. If the temperature inside the vehicle is lower than the preset temperature, you only need to turn on the single refrigeration mode, which helps to save energy.

[0083] In one embodiment, the air conditioning system control method further includes:

[0084] Determine if there is anyone inside the vehicle;

[0085] If the vehicle is unoccupied and the interior temperature is higher than the preset temperature, the air conditioning system's cooling mode will be off. This means that when no one is in the vehicle, there is no need to cool the interior, thus the cooling mode is off, saving energy and avoiding resource waste. If someone is in the vehicle and the interior temperature is higher than the preset temperature, the cooling mode will be turned on and off according to the above control method.

[0086] Specifically, a life detection device is installed inside the vehicle to detect whether there are people inside.

[0087] On the other hand, the present invention also provides a vehicle, including a controller and an air conditioning system as described in any of the above technical solutions, wherein the controller is configured to execute a vehicle air conditioning system control method as described in any of the above technical solutions.

[0088] In the above embodiments and various extended implementations, through the settings of the driving air conditioning system and the parking air conditioning system, regardless of whether the vehicle is in a driving state or a parking state, the corresponding mode can be selected based on the difference between the interior temperature and the preset temperature and the determination of whether there is food in the refrigerator compartment. This realizes the intelligent adjustment function of the refrigerator compartment and the vehicle interior cooling function, ensuring that the user's needs are not interrupted during driving and parking, and improving the user experience and the happiness of vehicle life.
