[0047] The present application provides a self-drying method of an air conditioner, an air conditioner, a readable storage medium, and a control system. The self-drying method of the present application, the air conditioner, the readable storage medium, and the control system are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0048] The present application provides an air conditioner, comprising a heat exchanger, a self-drying device and a control system. The self-drying device is used to remove water vapor generated by the heat exchanger. The control system is electrically connected to the heat exchanger and the self-drying device, and is used to control the self-drying device and the heat exchanger.

[0049] The self-drying method of the air conditioner provided in the present application is applied to the above-mentioned air conditioner, and the self-drying method is used to remove water vapor in the air conditioner.

[0050] Figure 1 Shown is a flow chart of an exemplary embodiment of the self-drying method of the present application. Figure 1 In the embodiment shown, the self-drying method of the present application includes steps 11-13:

[0051] Step 11, when the heat exchanger is working, obtain the ambient dew point temperature and the outlet air temperature of the heat exchanger. In some embodiments, the ambient dew point temperature can be used to characterize the temperature of the environment in which the air conditioner is located under a certain humidity. The heat exchanger can be an evaporator. The ambient dew point temperature and the outlet air temperature can be detected by a temperature sensor.

[0052] Step 12, determine the difference between the ambient dew point temperature and the outlet air temperature of the heat exchanger as the operating temperature difference. The larger the operating temperature difference, the larger the difference between the ambient dew point temperature and the outlet air temperature. The heat exchanger with a lower outlet air temperature will generate more water vapor when it encounters a higher ambient dew point temperature. By determining the operating temperature difference, it is helpful to improve the accuracy of judging the amount of water vapor generated.

[0053] Step 13, if the operating temperature difference is greater than the operating temperature setting difference, and when the operating temperature difference is greater than the operating temperature setting difference, the heat exchanger working time is greater than the set operating time, after the heat exchanger stops working, the self-drying device is controlled to dry the heat exchanger. The operating temperature difference being greater than the operating temperature setting difference can be used to indicate that the amount of water vapor generated may be large, and at this time, the generated water vapor needs to be dried to prevent the heat exchanger from being damp and moldy, and when the operating temperature difference is greater than the operating temperature setting difference, the heat exchanger working time is greater than the set operating time, indicating that under a large temperature difference, the condition of the heat exchanger generating water vapor has lasted for a long enough time, and under this condition, the amount of water vapor generated by the heat exchanger is larger, and the heat exchanger needs to be self-dried to remove a large amount of water vapor. By satisfying the conditions of the operating temperature setting difference and the set operating time, it is helpful to improve the accuracy of the judgment of the amount of water vapor generated, to dry the water vapor to a greater extent, and to reduce the power consumption waste caused by the long-term operation of the self-drying device. In addition, drying the heat exchanger after it stops working is helpful to avoid the negative impact on the user's experience during the drying process, and is conducive to achieving the drying function while ensuring the user experience.

[0054] Figure 2 Shown Figure 1 The self-drying method shown is a flow chart of an exemplary embodiment of the steps of controlling the self-drying device to dry the heat exchanger. Figure 2 In the embodiment shown, in step 13, the self-drying device is controlled to dry the heat exchanger, including steps 21-22:

[0055] Step 21, after the heat exchanger stops working, the cabin information of the vehicle is obtained, and the cabin information indicates whether there is anyone in the vehicle. In some embodiments, a camera installed inside the vehicle can be used to detect whether there is anyone in the vehicle, or an infrared temperature sensor installed inside the vehicle can be used to detect whether there is a living body in the vehicle, thereby determining whether there is anyone in the vehicle.

[0056] Step 22: If the cabin information is unmanned information indicating that there is no one in the vehicle, the self-drying device is controlled to dry the heat exchanger. Since the self-drying device is likely to generate a lot of noise when drying the heat exchanger, the self-drying device can be controlled to dry the heat exchanger when the user is not present, thereby achieving self-drying of the heat exchanger and reducing the impact on the user's riding comfort, which is conducive to improving the user's use experience.

[0057] In some embodiments, in step 22, controlling the self-drying device to dry the heat exchanger includes: if the duration of the unmanned information is longer than the parking time, controlling the self-drying device to dry the heat exchanger. By setting the heat exchanger to be dried only after the duration of the unmanned information is longer than the parking time, it is helpful to reduce the impact of the self-drying of the heat exchanger on the user. Since the user has just got off the vehicle, the user is still close to the vehicle, and the noise generated by the self-drying device when drying the heat exchanger is relatively large, immediately controlling the self-drying device to dry the heat exchanger at this time is likely to cause a large noise disturbance to the user. By setting the drying after the parking time is met, it is helpful to improve the user's experience. In addition, if the duration of the unmanned information is short, it can be determined that the heat exchanger has just stopped working for a short time, and the difference with the ambient temperature is still large. At this time, the temperature of the heat exchanger is low and the humidity is high. Self-drying after being longer than the parking time is conducive to self-drying under relatively low humidity conditions, which is conducive to reducing the energy consumption of the self-drying device.

[0058] Figure 3 Shown Figure 1 The self-drying method shown is a flow chart of another exemplary embodiment of the steps of controlling the self-drying device to dry the heat exchanger. Figure 3 In the embodiment shown, in step 13, the self-drying device is controlled to dry the heat exchanger, including steps 31-32:

[0059] Step 31, after the heat exchanger stops working, the vehicle locking information is obtained, and the locking information indicates whether the vehicle is locked. In some embodiments, the vehicle can be locked by a remote control device or automatically locked after the remote control device and the person leave a certain distance. In some embodiments, the locking information of the entire vehicle can be obtained by obtaining the locking status information of the vehicle windows or doors.

[0060] Step 32: If the vehicle lock information is information indicating that the vehicle is locked, the self-drying device is controlled to dry the heat exchanger. If the vehicle is locked, it means that the user no longer needs to use the vehicle and the vehicle is in an idle state. Since the noise generated during the drying of the heat exchanger is relatively large, drying the heat exchanger when the vehicle is idle is beneficial to reduce the impact on the user to a lower level and improve the user's experience.

[0061] In some embodiments, in step 32, the self-drying device is controlled to dry the heat exchanger, including: if the duration of the locked vehicle information is longer than the vehicle locking time, the self-drying device is controlled to dry the heat exchanger. The duration of the locked vehicle information being longer than the vehicle locking time indicates that the vehicle has been locked for a long time, and also indicates that the user does not need to use the vehicle during this period of time, and thus it can be determined that the user is not near the vehicle. At this time, controlling the self-drying device to dry the heat exchanger has less impact on the user. Furthermore, if the duration of the locked vehicle information is short, it can be determined that the heat exchanger has just stopped working not long ago, and the difference with the ambient temperature is still large. At this time, the temperature of the heat exchanger is low and the humidity is high. Self-drying after being longer than the vehicle locking time is more conducive to self-drying under relatively low humidity conditions, which is conducive to reducing the energy consumption of the self-drying device.

[0062] In some embodiments, the user continues driving for a period of time after turning off the heat exchanger. At this time, the self-circulation of air inside the vehicle makes the operating temperature difference smaller. After driving, the user locks the vehicle. At this time, the detected operating temperature difference does not meet the set operating temperature difference. There is no need to automatically turn on the self-drying device to dry the heat exchanger. In some embodiments, the user can dry the heat exchanger by manually turning on the self-drying device.

[0063] Figure 4 Shown Figure 1 The flowchart of another exemplary embodiment of the steps of controlling the self-drying device to dry the heat exchanger in the self-drying method shown. Figure 4 In the embodiment shown, in step 13, the self-drying device is controlled to dry the heat exchanger, including steps 41-43:

[0064] Step 41, obtaining the temperature of the coolant in the air conditioner. The temperature of the coolant in the air conditioner can be measured by placing a temperature sensor at a location where the coolant flows in the air conditioner.

[0065] Step 42, determine the difference between the coolant temperature and the outlet air temperature of the heat exchanger as the heat exchange temperature difference. The heat exchange temperature difference can be used to characterize the residual amount of water vapor, so as to facilitate the judgment of whether it is necessary to continue to remove water vapor. The larger the heat exchange temperature difference, the more water vapor is generated inside the heat exchanger, and the smaller the heat exchange temperature difference, the less water vapor is left inside the heat exchanger. In some embodiments, the difference between the ambient temperature and the outlet air temperature of the heat exchanger can also be obtained as a standard for judging the residual amount of water vapor. The larger the difference between the ambient temperature and the outlet air temperature of the heat exchanger, the more water vapor is generated.

[0066] Step 43, if the heat exchange temperature difference is less than or equal to the heat exchange temperature setting difference, control the self-drying device to stop drying the heat exchanger. When the heat exchange temperature difference is less than the heat exchange temperature setting difference, it means that the water vapor inside the heat exchanger is less at this time, and the heat exchanger does not need to be dried. If the heat exchanger is controlled to continue to be dried, unnecessary power consumption will be generated. Therefore, controlling to stop drying is conducive to reducing power consumption when the water vapor is less, which is conducive to energy saving and emission reduction.

[0067] Step 44, if the heat exchange temperature difference is greater than the heat exchange temperature setting difference, control the self-drying device to continue drying the heat exchanger. When the heat exchange temperature difference is greater than the heat exchange temperature setting difference, it means that the water vapor inside the heat exchanger is relatively large at this time, and the heat exchanger needs to be dried continuously to avoid the heat exchanger from getting moldy due to moisture, which is beneficial to improving the riding experience of users.

[0068] Figure 5 Shown Figure 1 The self-drying method shown in the figure is a flow chart of another exemplary embodiment of the steps of controlling the self-drying device to dry the heat exchanger. Figure 5 In the embodiment shown, the self-drying device includes a blower, and step 13 controls the self-drying device to dry the heat exchanger, including steps 51-53:

[0069] Step 51, obtaining the wind speed of the blower. In some embodiments, the wind speed of the blower can be measured by an anemometer.

[0070] Step 52, determining the first working time of the blower according to the wind speed, the greater the wind speed, the shorter the first working time. The greater the wind speed of the blower, the better the effect of drying the water vapor in the heat exchanger, and the shorter the required drying time. When the blower dries most of the water vapor, the blower can be controlled to stop drying for the purpose of energy saving and emission reduction. Therefore, the greater the wind speed of the blower, the shorter the time for the blower to perform drying work is set.

[0071] Step 53, control the blower to dry the heat exchanger for a first working time. Control the blower to dry for the first working time so that the blower can fully dry the water vapor inside the heat exchanger, and only control the blower to work for the first working time, which is conducive to avoiding energy waste caused by dry blowing of the blower when there is no water vapor.

[0072] Figure 6 Shown Figure 1 The flowchart of another exemplary embodiment of the steps of controlling the self-drying device to dry the heat exchanger in the self-drying method shown. Figure 6 In the embodiment shown, in step 13, the self-drying device is controlled to dry the heat exchanger, including steps 61-63:

[0073] Step 61, obtaining the ambient humidity. In some embodiments, the ambient humidity can be measured by setting a humidity detector.

[0074] Step 62, determining the second working time of the self-drying device according to the ambient humidity, the higher the ambient humidity, the longer the second working time. The higher the humidity, the more residual water vapor in the heat exchanger, and the longer the required drying time. Therefore, the higher the ambient humidity data obtained, the longer the working time of the self-drying device needs to be controlled to perform drying.

[0075] Step 63, control the self-drying device to dry the heat exchanger for a second working time. Control the drying working time of the self-drying device to the second working time, so that the self-drying device can fully dry the water vapor inside the heat exchanger, and only control the self-drying device to work for the second working time, which is conducive to avoiding energy waste caused by dry blowing of the self-drying device when there is no water vapor.
