[0001] The present application relates to the field of air conditioning control, and in particular to an air conditioning control method, electronic equipment, a vehicle, and a computer-readable storage medium. Background Art

[0002] When the temperature of a car's window glass reaches or is lower than the dew point of the air inside the car, the moisture contained in the air inside the car will condense into water droplets on the surface of the glass inside the car. This phenomenon is usually called vehicle interior fogging.

[0003] At present, humidity sensors can be configured inside the vehicle to determine the risk of fogging inside the vehicle. When there is a risk of fogging inside the vehicle, the air conditioner in the vehicle can be used to reduce the humidity inside the vehicle, thereby reducing the risk of fogging in the vehicle.

[0022] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the implementation methods of the present application and the features in the implementation methods can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present application. The described implementations are only part of the implementations of the present application, rather than all the implementations.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] It should be further noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0026] In this application, "at least one" means one or more, and "more" means two or more than two. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0027] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0028] At present, a humidity sensor can be configured inside the vehicle to determine the risk of fogging inside the vehicle. When there is a risk of fogging inside the vehicle, the air conditioner inside the vehicle can be used to reduce the humidity inside the vehicle, thereby reducing the risk of fogging inside the vehicle. For example, an evaporator can be used to reduce the humidity inside the vehicle.

[0029] However, the above method relies on a humidity sensor, and when a humidity controller is not configured in the vehicle, it is difficult to reduce the risk of fogging inside the vehicle.

[0030] Therefore, in some embodiments, when the ambient temperature is low, for example, in winter, the air conditioner can close the inner circulation damper and adjust the opening of the outer circulation damper to the maximum value.

[0031] Among them, the internal circulation damper can control the air circulation in the car.

[0032] The external circulation damper can bring the air outside the car into the car. The damper opening refers to the degree of opening of the damper. The damper opening may be presented in the form of a percentage or in other ways, and the embodiments of the present application are not limited to this.

[0033] For example, if the opening of the internal circulation damper is 0%, it means that the internal circulation damper is closed; if the opening of the internal circulation damper is 100%, it means that the vehicle's air-conditioning system only circulates air in the vehicle and does not introduce air from outside the vehicle; if the opening of the external circulation damper is 100%, it means that the vehicle's air-conditioning system mainly obtains air from outside the vehicle and delivers it into the vehicle.

[0034] Since the air inlet temperature of the external circulation damper is low and the air humidity is low, the above method can reduce the risk of fogging inside the vehicle.

[0035] However, since the air inlet temperature of the external circulation damper is relatively low, the temperature of the passenger compartment will be relatively low. In a low temperature environment, users generally have heating needs, and the air conditioner needs to consume more electricity to heat the air. Therefore, the above method will cause excessive energy consumption of the vehicle air conditioner.

[0036] Furthermore, the internal circulation opening can be increased, and the air conditioning energy consumption can be reduced by increasing the internal circulation opening.

[0037] The following analyzes the impact of the vehicle's internal and external circulation openings on vehicle energy consumption.

[0038] The cooling load of the passenger compartment is recorded as , which is calculated as follows: in, Transfer heat to the car body. Heat transfer to glass, is the fresh air heat, It is the heat from the electrical appliances in the car and the human body.

[0039] Assuming the current ambient temperature is -18 degrees, the fresh air flow is 320m³ / h, and the temperature inside the car is required to reach 15 degrees. Through theoretical calculation, we can get =7.26KW.

[0040] Among them, the fresh air heat accounts for 53%. =1.86KW; =1.56KW; =3.86KW; =0.278KW.

[0041] When the vehicle internal circulation accounts for 30% and the external circulation accounts for 70%, =2.1KW, cooling load reduced by 1.76KW, heat reduced by 24%.

[0042] When the vehicle's internal circulation accounts for 70% and the external circulation accounts for 30%, =0.6KW, cooling load is reduced by 3.26KW, and heat is reduced by 44.9%.

[0043] From the above, we can see that the greater the proportion of internal circulation during winter heating, the lower the energy consumption of vehicle air conditioning. However, if the internal circulation is too large, it is impossible to ensure that the humidity in the car is at a low state, and the risk of fogging is still high.

[0044] In view of the above, the embodiments of the present application provide an air conditioning control method, an electronic device, a vehicle and a computer-readable storage medium. The embodiments of the present application can reasonably control the opening of the inner circulation damper and the outer circulation damper without relying on a humidity sensor to reduce the risk of fogging in the vehicle and save air conditioning energy consumption.

[0045] refer to Figure 1 As shown, Figure 1 A schematic diagram of an air conditioner provided in accordance with an embodiment of the present application.

[0046] The air conditioner at least comprises an inner circulation damper, an outer circulation damper, a blower, an evaporator, a compressor, a condenser, a throttle valve and electronic equipment. The electronic equipment can be connected to the inner circulation damper, the outer circulation damper, the blower, the evaporator and the compressor for communication.

[0047] Among them, the internal circulation damper is the damper that allows the air inside the car to enter the air conditioner.

[0048] The external circulation damper is the damper that allows air outside the car to enter the air conditioner.

[0049] The blower is used to accelerate the air entering the air conditioner and transfer it to the evaporator.

[0050] The evaporator is used to vaporize the refrigerant in the vehicle, thereby absorbing heat from the air.

[0051] The compressor is used to compress the refrigerant gas, changing it from low-temperature and low-pressure refrigerant gas to high-temperature and high-pressure refrigerant gas.

[0052] The condenser is used to condense the refrigerant gas in a high-temperature and high-pressure state into a medium-temperature and high-pressure liquid refrigerant. During the condensation process, the refrigerant will dissipate heat and transfer the heat to the surrounding air or water.

[0053] The throttle valve is used to convert medium-temperature and high-pressure liquid refrigerant into low-temperature and low-pressure liquid refrigerant.

[0054] The electronic device can be used to execute the air conditioning control method provided in the embodiment of the present application. The air conditioning refrigeration method may include: obtaining the outside temperature of the vehicle; if the outside temperature is less than a preset first temperature threshold, determining the target return air temperature of the air conditioner based on the outside temperature, the target return air temperature being the return air temperature of the air conditioner when no fogging occurs inside the vehicle and the vehicle is at the outside temperature; obtaining the actual return air temperature of the air conditioner; and adjusting the inner circulation damper opening and the outer circulation damper opening based on the target return air temperature and the actual return air temperature.

[0055] When the outside temperature (i.e., the ambient temperature) is lower than the first temperature threshold, it means that the outside temperature is low, and users generally have a heating demand. At this time, the temperature difference between the inside and outside of the vehicle is large, and there is a certain risk of fogging in the vehicle. Therefore, the embodiment of the present application can obtain the target return air temperature, and adjust the opening of the internal and external circulation dampers based on the actual return air temperature and the target return air temperature, so that the return air temperature of the air conditioner is maintained at the target return air temperature, thereby reducing the risk of fogging in the vehicle at the outside temperature without relying on the humidity sensor. Moreover, the embodiment of the present application can reasonably adjust the opening of the internal circulation damper and the opening of the external circulation damper according to the target return air temperature, which can reduce the energy consumption of the air conditioner compared to adjusting the opening of the external circulation damper to the maximum value.

[0056] That is, the embodiment of the present application can reduce the risk of fogging inside the vehicle without relying on a humidity sensor, and is beneficial for reducing air conditioning energy consumption.

[0057] The above-mentioned air conditioner is only an example. In actual application, its specific structure may be different, and the embodiments of the present application are not limited to this.

[0058] Figure 2 The present invention is a flowchart of the steps of an embodiment of an air conditioning control method of the present invention. The air conditioning control method uses an electronic device, and the electronic device is used to control the air conditioning in a vehicle.

[0059] According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

[0060] See also Figure 2 As shown, the air conditioning control method may include the following steps.

[0061] Step 201, obtaining the vehicle's outside temperature.

[0062] The temperature outside the vehicle is also called the ambient temperature.

[0063] In some embodiments, the vehicle is equipped with a temperature sensor outside the vehicle body, and the electronic device can obtain the outside temperature of the vehicle from the temperature sensor.

[0064] In other embodiments, the electronic device may obtain the outside temperature of the vehicle from a server storing real-time weather information.

[0065] The above method of obtaining the vehicle's outdoor temperature is only an example and is not limited in this application.

[0066] Step 202: If the outside temperature of the vehicle is lower than a preset first temperature threshold, a target return air temperature of the air conditioner is determined based on the outside temperature of the vehicle.

[0067] Among them, the first temperature threshold can be set according to actual application needs. When the temperature outside the vehicle is lower than the first temperature threshold, the user generally only has heating demand but no cooling demand, and the air conditioner is generally in the heating mode.

[0068] The value of the first temperature threshold may be between 3 degrees and 6 degrees, for example, 5 degrees, which is not limited in the embodiment of the present application.

[0069] The target return air temperature is the return air temperature of the air conditioner when fogging does not occur inside the vehicle and the vehicle is at the outside temperature.

[0070] Furthermore, the target return air temperature may be a maximum return air temperature that the air conditioner can reach when no fogging occurs inside the vehicle and the vehicle is at the outside temperature.

[0071] That is, when the vehicle is at the outside temperature and the return air temperature of the air conditioner is greater than the maximum return air temperature, there is a high probability that fogging will occur inside the vehicle.

[0072] In a low temperature environment, the higher the return air temperature of the air conditioner, the less energy is required for air conditioning heating. However, the higher the return air temperature of the air conditioner, the higher the probability of fogging in the car. Therefore, the target return air temperature of the embodiment of the present application is the above-mentioned maximum return air temperature, which can minimize the energy consumption of the air conditioner while ensuring that the car does not fog up as much as possible, thereby reducing the energy consumption of the vehicle in a low temperature environment.

[0073] In some embodiments, step 202 may be implemented in the following manner: First, in a pre-stored relationship table between the vehicle exterior temperature and the return air temperature, the return air temperature corresponding to the vehicle exterior temperature is searched to obtain a calibrated return air temperature.

[0074] The relationship table includes the outside temperature of the vehicle and the return air temperature of the air conditioner when the vehicle is at the outside temperature and no fogging occurs inside the vehicle.

[0075] The relationship table of the embodiment of the present application can be obtained through calibration experiments. For example, a vehicle is placed in a certain ambient temperature, and the return air temperature of the air conditioner is gradually adjusted. If the return air temperature of the air conditioner is greater than a certain value, the interior of the vehicle begins to fog up, and if the return air temperature of the air conditioner is less than the value, the vehicle does not fog up. The value can be used as the return air temperature corresponding to the ambient temperature and stored in the relationship table, so that the calibrated return air temperature can be found from the relationship table later.

[0076] After the calibrated return air temperature is acquired, the target return air temperature may be determined based on the calibrated return air temperature.

[0077] For example, the calibrated return air temperature may be used as the target return air temperature.

[0078] For another example, the electronic device may obtain the current speed of the vehicle; and correct the calibrated return air temperature based on the current speed to obtain the target return air temperature.

[0079] The higher the vehicle speed, the lower the vehicle glass temperature and the lower the dew point temperature. At this time, the vehicle is more likely to fog. Therefore, when the current vehicle speed is high, the calibrated return air temperature can be lowered to obtain the target return air temperature.

[0080] Furthermore, the higher the current vehicle speed, the greater the reduction gradient of the calibrated return air temperature. The reduction gradient can be configured according to actual application requirements, and the embodiments of the present application are not limited to this.

[0081] When determining the target return air temperature, the embodiment of the present application also takes the vehicle speed into consideration, thereby improving the accuracy of the target return air temperature and further reducing the risk of fogging in the vehicle.

[0082] Step 203: Obtain the actual return air temperature of the air conditioner.

[0083] For example, a temperature sensor can be configured on the evaporator. When the temperature outside the vehicle is lower than the first temperature threshold, the electronic device can control the evaporator temperature to stop working. In this case, the temperature measured by the temperature sensor is the actual return air temperature. The temperature sensor can transmit the actual return air temperature to the electronic device so that the electronic device can obtain the actual return air temperature.

[0084] Step 204: adjusting the opening of the inner circulation damper and the opening of the outer circulation damper based on the target return air temperature and the actual return air temperature.

[0085] In some embodiments, the electronic device can perform proportional integral adjustment (PI adjustment) on the difference between the target return air temperature and the actual return air temperature to obtain the inner circulation damper opening and the outer circulation damper opening, so that the actual return air temperature of the air conditioner can reach the target return air temperature and maintain at the target return air temperature.

[0086] In some embodiments, when the outside temperature of the vehicle is less than the first temperature threshold, in addition to adjusting the inner circulation damper opening and the outer circulation damper opening according to the above steps 201 to 204, the evaporator can also be controlled to stop working.

[0087] Since the outside temperature is lower than the first temperature threshold, it indicates that the current temperature is relatively cold and the air conditioner does not need to provide a cooling function. Therefore, the evaporator can be controlled to stop working, thereby reducing the energy consumption of the air conditioner.

[0088] When the outside temperature of the vehicle is greater than the first temperature threshold, the electronic device may also adjust the internal circulation damper, the external circulation damper and the evaporator.

[0089] When the outside temperature is greater than the first temperature threshold, the evaporator is adjusted as follows: If the outside temperature is greater than the first temperature threshold and less than the preset second temperature threshold, it means that the air conditioner is generally in a pure cooling mode, or a cooling-based and heating-assisted mode. In this case, the electronic device can obtain the requested air outlet temperature; and determine the evaporation temperature of the evaporator based on the requested air outlet temperature.

[0090] For example, the evaporation temperature corresponding to the requested air outlet temperature may be found out by a table lookup method, but the method is not limited thereto. The embodiment of the present application does not limit the method of calculating the evaporation temperature of the evaporator based on the requested air outlet temperature. The above-mentioned requested air outlet temperature is the air outlet temperature that the air conditioner is requested to reach.

[0091] In automatic air conditioning mode, users can also configure the perceived temperature, and the air conditioner can automatically switch between cooling mode and heating mode based on the perceived temperature. In automatic air conditioning mode, the cooling and heating modes of the air conditioner include: 1. Pure cooling mode. For example, when the outside temperature is higher than 25 degrees, the air conditioner is in pure cooling mode.

[0092] 2. The mode with cooling as the main function and heating as the auxiliary function. For example, when the outside temperature is between 15-25 degrees, the air conditioner is in this mode.

[0093] 3. A mode that uses heating as the main function and cooling as the auxiliary function. For example, when the outside temperature is between 5 and 15 degrees, the air conditioner is in this mode.

[0094] The second temperature threshold may be determined by a critical temperature at which the air conditioner switches between the three modes.

[0095] Specifically, when the outside temperature is greater than the second temperature threshold, the air conditioner is in a mode of mainly heating and mainly cooling; when the outside temperature is less than the second temperature threshold, the air conditioner is in a mode of mainly cooling and supplemented by heating, or a pure cooling mode. For example, the second temperature threshold can be set to the above-mentioned 15 degrees, but is not limited thereto.

[0096] The above is the case where the outside temperature is between the first temperature threshold and the second temperature threshold. In some embodiments, if the outside temperature is greater than the second temperature threshold, it means that the air conditioner is in a mode with heating as the main and cooling as the auxiliary. At this time, the electronic device can determine the evaporation temperature of the evaporator according to the outside temperature.

[0097] For example, the evaporation temperature corresponding to the vehicle outside temperature can be found by looking up a table. Generally speaking, the evaporation temperature is 1 to 2 degrees lower than the vehicle outside temperature.

[0098] Furthermore, the evaporation temperature of the evaporator needs to be no greater than a preset odor calibration temperature. That is, when the evaporation temperature is greater than the odor calibration temperature, odor is likely to appear inside the vehicle. Therefore, if the evaporation temperature calculated in the above manner exceeds the odor calibration temperature, the evaporation temperature is changed to the odor calibration temperature to avoid odor in the vehicle.

[0099] When the outside temperature is greater than the first temperature threshold, the control methods of the internal circulation damper and the external circulation damper are different for different types of air conditioners to adapt to the structural characteristics of different types of air conditioners. For example, heat pump type air conditioners and non-heat pump type air conditioners may have different damper control methods.

[0100] Vehicles equipped with heat pump air conditioners can be called heat pump models. The heating and cooling of heat pump air conditioners are both achieved by compressors. When the heating capacity is insufficient, a practical heater is used to compensate for the heat.

[0101] Vehicles equipped with non-heat pump air conditioners can be called non-heat pump models. Non-heat pump air conditioners use compressors to cool and heaters to heat.

[0102] refer to Figure 3 As shown, when the air conditioner is a non-heat pump air conditioner and the outside temperature is greater than the first temperature threshold, the control steps of the inner circulation damper and the outer circulation damper include: Step 301, obtaining the temperature inside the vehicle.

[0103] For example, a temperature sensor is provided in the vehicle, and the electronic device can obtain the temperature in the vehicle from the temperature sensor.

[0104] Step 302, detecting whether the temperature inside the vehicle is greater than the temperature outside the vehicle.

[0105] If the temperature inside the vehicle is greater than the temperature outside the vehicle, step 303 is performed. If the temperature inside the vehicle is less than the temperature outside the vehicle, step 304 is performed.

[0106] Step 303, controlling the opening of the outer circulation damper to be greater than the opening of the inner circulation damper.

[0107] When the temperature inside the vehicle is greater than the temperature outside the vehicle, the larger the opening of the inner circulation damper is, the higher the inlet air temperature at the evaporator is. The higher the inlet air temperature is, the higher the energy consumption of the compressor is. Therefore, in this case, controlling the opening of the outer circulation damper to be greater than the opening of the inner circulation damper is beneficial to reducing the energy consumption of the compressor and thus reducing the energy consumption of the air conditioner.

[0108] Furthermore, if the temperature inside the vehicle is greater than the temperature outside the vehicle, the electronic device may close the inner circulation damper and adjust the opening of the outer circulation damper to the maximum.

[0109] If the temperature inside the vehicle is lower than the temperature outside the vehicle, step 304 is executed.

[0110] Step 304, controlling the opening of the outer circulation damper to be smaller than the opening of the inner circulation damper.

[0111] For example, the electronic device can close the external circulation damper and adjust the internal circulation damper opening to the maximum to achieve energy saving.

[0112] refer to Figure 4 As shown, when the air conditioner is a heat pump type air conditioner and the outside temperature of the vehicle is greater than the first temperature threshold, the control steps of the inner circulation damper and the outer circulation damper include: Step 401, obtaining the blower air volume of the air conditioner and the requested air outlet temperature of the air conditioner.

[0113] Step 402, in the pre-stored internal and external circulation damper opening table, search for the internal circulation damper opening and the external circulation damper opening corresponding to the blower air volume and the requested air outlet temperature to obtain the target internal and external circulation damper opening.

[0114] The internal and external circulation damper opening table includes the internal circulation damper opening and the external circulation damper opening when the air conditioner energy consumption reaches the minimum value under different blower air volumes and requested air outlet temperatures.

[0115] In some embodiments, the inner circulation damper opening and the outer circulation damper opening in the inner and outer circulation damper opening table may be obtained based on experiments.

[0116] For example, the vehicle's blower air volume and requested air outlet temperature are set to remain unchanged at the experimental values, the inner circulation damper opening and the outer circulation damper opening are adjusted and the air conditioning energy consumption is measured. When the air conditioning energy consumption reaches the minimum value, the inner circulation damper opening and the outer circulation damper opening are recorded to obtain the inner circulation damper opening and the outer circulation damper opening corresponding to different blower air volumes and requested air outlet temperatures in the inner and outer circulation damper opening table.

[0117] Step 403: Control the internal circulation damper and the external circulation damper based on the target internal and external circulation damper opening.

[0118] In some embodiments, the electronic device may configure the opening values ​​of the internal circulation damper and the external circulation damper to be the target internal and external circulation damper openings.

[0119] In other embodiments, step 403 can be implemented as follows: if the compressor reaches the minimum speed and the pressure of the compressor exceeds a preset pressure value, the inner circulation damper opening in the target inner and outer circulation damper opening is reduced, and / or the outer circulation damper opening in the target inner and outer circulation damper opening is increased to obtain a corrected inner and outer circulation damper opening; based on the corrected inner and outer circulation damper opening, the inner circulation damper and the outer circulation damper are controlled, for example, the openings of the inner circulation damper and the outer circulation damper are configured to be the corrected inner and outer circulation damper openings.

[0120] The preset pressure value is a critical value that causes the compressor to stop running.

[0121] When the air conditioner is a heat pump air conditioner, if the compressor pressure is too high, the compressor will stop running. Therefore, by reducing the opening of the inner circulation damper and increasing the opening of the outer circulation damper, the high pressure of the compressor can be alleviated to avoid frequent starting and stopping.
