If the current air outlet temperature of the air conditioner is within the first preset temperature range, cooling treatment can be performed according to the first cooling strategy.

[0033] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0034] When air conditioning is used for extended periods, hot, humid air condenses into water droplets when it contacts the cooler air duct walls. This accumulation of water droplets can damage vehicle components and significantly impact electrical components. Furthermore, the dripping water can negatively impact the user's riding experience. Therefore, reducing the amount of condensation generated during vehicle air conditioning operation, and thus minimizing the risk of electrical component failure due to condensation, has become a pressing issue.

[0035] Based on this, in order to solve the above problems, the embodiments of the present application provide cooling strategies for different situations. Through the above cooling strategies, the ambient temperature in the car can be reduced to a temperature range where no condensation water will be generated, thereby reducing the condensation water generated during the operation of the car air conditioner, thereby reducing the failure of electrical components due to condensation water, and improving the user's riding experience.

[0036] The specific implementation of the condensate control method and device in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1 , which is a flow chart of a condensed water control method provided in an embodiment of the present application, combined with Figure 1 Specifically, it may include:

[0038] S101: When the condensate mass of the entire vehicle is less than a preset threshold, if the current air outlet temperature of the air conditioner is within a first preset temperature range, the first condensate area and the air outlet temperature are cooled according to a first cooling strategy to reduce the ambient temperature in the vehicle to within a second preset temperature range.

[0039] According to the enthalpy-humidity diagram of the physical characteristics of air, it can be determined whether condensation will occur on the air conditioning box shell and the air duct wall when the cold air from the air conditioner passes through the air conditioning box and blows into the air duct. Figure 2 , Figure 2 This is a schematic diagram of the air conditioning condensation line provided in an embodiment of the present application. The two different condensation lines in the figure represent schematic lines that will produce condensation at different air conditioning outlet temperatures. Figure 2 The horizontal axis is the ambient temperature inside the car, and the vertical axis is the ambient humidity inside the car.

[0040] For example, the air outlet temperature of a car air conditioner is 15℃-30℃. Figure 2 The condensation line is drawn based on the above outlet air temperature. When the ambient temperature is 40℃, the ambient humidity is 80%, and the outlet air temperature of the air conditioner is 20℃, Figure 2 As you can see, condensation only occurs at the 20°C air conditioning condensation line when the ambient temperature is above 23°C. The current ambient temperature is 40°C, far exceeding the condensation temperature. Therefore, condensation will form on the AC housing and air duct. In other words, if the current ambient temperature and humidity are to the right of the set air conditioning cold air outlet temperature condensation line, condensation will form. The farther away from the condensation line, the faster the condensation, and the longer the state lasts, the greater the amount of condensation.

[0041] There are two condensation processes in car air conditioners, which can be referred to Figure 3 , Figure 3 This is a schematic diagram of the structure of generating condensed water provided in the embodiment of the present application. The first process (i.e. Figure 3 The first part is that inside the air conditioner, the hot and humid air sucked in from the air conditioner blower exchanges heat with the refrigeration components inside the air conditioner, which will produce condensed water. This condensation process will produce a lot of condensed water due to the large temperature difference, but the condensed water produced in this process can be discharged to the outside of the car through the water pipe of the air conditioner; the second process (i.e. Figure 32) in the preceding text refers to the cold air flowing from the air conditioner into the vehicle, which exchanges heat with the hot, humid air inside the vehicle on the AC unit housing and duct walls, producing condensation. While the temperature difference during this condensation process is relatively small, excessive condensation can still form over time and drip onto electrical components, potentially causing failure and affecting the passenger experience.

[0042] Typically, the temperature during the first process is 10-20°C lower than the temperature during the second process, and a large amount of condensed water is generated first during the first process. Therefore, based on the aforementioned condensation characteristics and the two condensation processes in a car air conditioner, this application controls and reduces the amount of condensed water generated in the car air conditioner, thereby reducing damage to the car's electrical components.

[0043] In one possible implementation, reference may be made to Figure 4 , Figure 4 The structural schematic diagram for obtaining parameters provided in the embodiment of the present application can detect the air outlet temperature of the air conditioner through the air duct temperature sensor, and a temperature sensor for the cooling area of ​​the air-conditioning box can be added to the whole vehicle to detect the cooling temperature of the air conditioner through the temperature sensor in the cooling area of ​​the air-conditioning box; an interior environment humidity sensor can be added to the whole vehicle to detect the interior environment humidity through the interior environment humidity sensor; an exterior environment humidity sensor can be added to the whole vehicle to detect the exterior environment humidity through the exterior environment humidity sensor; an interior environment temperature sensor can be added to the whole vehicle to detect the interior environment temperature through the interior environment temperature sensor; a door and window opening time sensor can be added to the whole vehicle to detect the opening time of the doors and windows through the door and window opening time sensor, thereby providing data support for the cooling process based on the above parameters, facilitating the rapid acquisition of the above parameters, and thus improving the efficiency of the cooling process.

[0044] In a possible implementation, a treatment method for reducing condensed water may be determined based on the quality of the condensed water. Before determining the treatment method for reducing condensed water based on the quality of the condensed water, the quality of the condensed water may be determined first.

[0045] As an example, the dew point temperature of condensed water can be determined based on air temperature and relative humidity. The condensed water mass can then be determined based on the dew point temperature, duct surface area, air temperature, door and window opening time, and the condensation coefficient. For example, the air ducts on typical cars are made of plastic. Different plastics have different heat transfer coefficients. Based on the heat transfer coefficients of different materials, it can be seen that the higher the thermal conductivity of a plastic, the more likely it is to form condensed water. The thermal conductivity coefficients of different plastics can be found in Table 1.

[0046] Table 1

[0047]

[0048]

[0049] The heat transfer rate of a material is proportional to the heat conduction system. For example, the mass of condensed water can be determined experimentally based on a 1.5 mm thick high-density polyethylene air duct of an experimental vehicle model.

[0050] The dew point temperature refers to the temperature at which water vapor in the air begins to condense into liquid water (i.e., condensed water) when the water vapor in the air cools to a certain degree. The method for determining the dew point temperature can refer to Formula 1.

[0051]

[0052] Among them, T d It represents dew point temperature (°C), T refers to air temperature (°C), and RH refers to relative humidity (%).

[0053] After determining the dew point temperature, for a surface area of ​​A (m 2 ) for the air duct, if the surface temperature of the air duct is T s (℃), and T s <T d The quality of condensed water can be referred to Formula 2.

[0054] m=A*(T d -T s )*Δt*k Formula 2

[0055] Among them, k (g / m2·℃·h) represents the condensation coefficient, which is related to parameters such as material thermal conductivity, surface properties, and thickness. Δt represents the time the car door and window are open. Since the duct material, thickness, and manufacturing method used in the experiment are the same, k can be used as a constant. In addition, the duct surface temperature T s There is a difference between the temperature and the air temperature T, but in practical application scenarios, the accuracy requirement is low, so it is set to T s =T, accordingly, Formula 2 can be transformed into Formula 3, and the mass of the condensed water can be determined according to Formula 3.

[0056] m=A*(T d -T)*Δt*k Formula 3

[0057] According to the experiment of calculating the mass of condensed water, when m>=8k, condensed water droplets have already formed in the air duct. If it is hit with a small hammer (simulating bumpy road conditions), a small amount of condensed water will drip.

[0058] Therefore, if m is less than 8k, condensation can be reduced in the first process where condensation occurs. The preset threshold value is used to indicate whether the condensation of the current vehicle can be partially reduced in the first process. For example, the preset threshold value may be 8k. If the mass of the condensation water in the vehicle, m, is less than 8k, it indicates that the condensation of the current vehicle can be partially reduced in the first process through cooling treatment. If the mass of the condensation water in the vehicle, m, is not less than 8k, that is, m>=8k, it indicates that the condensation of the current vehicle cannot be partially reduced in the first process through cooling treatment, and cooling treatment is required in the second process.

[0059] As an example, after the condensation water mass of the entire vehicle is calculated based on various parameters in the automobile air-conditioning refrigeration environment, when m<8k, if the current air outlet temperature of the air conditioner is within the first preset temperature range, the first condensation water area and the air outlet temperature can be cooled according to the first cooling strategy to reduce the ambient temperature in the vehicle to within the second preset temperature range.

[0060] The first condensation water region refers to the first process in which condensation water is generated, the first preset temperature range is used to indicate the temperature range in which condensation water is generated, and the second preset temperature range is used to indicate the temperature range in which condensation water is not generated. Figure 5 , Figure 5 This is a schematic diagram of the first cooling treatment method provided in the embodiment of the present application. Figure 5 The yellow zone refers to the first preset temperature range, the red zone refers to the air temperature greater than the first preset temperature range, and the green zone refers to the second preset temperature range.

[0061] For example, if the current air outlet temperature of the air conditioner is in the yellow zone, then the reverse L-shaped cooling control can be performed, that is, first, the air outlet temperature of the car air conditioner in the second process where condensed water will be generated can be controlled to be the same as the current ambient temperature in the car, and then the cooling temperature in the first condensed water area can be gradually lowered, that is, the temperature of the evaporator in the first process (i.e., the cooling temperature) can be gradually lowered, so that the humidity of the hot and humid air in the car decreases, until the moisture in the air in the car is reduced by the cooling treatment method in the first process, and the humidity is reduced to an appropriate value, such as after the ambient humidity is reduced to the left of the condensation line, the air outlet temperature of the air conditioner is lowered, so that the ambient temperature in the car can be reduced to the green zone. Figure 5 It can be seen that the cooling process of the above-mentioned first cooling strategy looks like an inverted L-shape. Therefore, the first cooling strategy can also be called an inverted L-shaped cooling control, which reduces the generation of condensed water in the first process, thereby reducing the failure of electrical components due to condensed water, and at the same time improves the user's riding experience.

[0062] S102: When the condensate water quality is less than a preset threshold and the outlet air temperature is greater than a first preset temperature range, the first condensate water area and the outlet air temperature are cooled according to a second cooling strategy, and the air volume of the air conditioner is adjusted.

[0063] As an example, after the condensation water mass of the entire vehicle is calculated based on various parameters in the automobile air-conditioning refrigeration environment, when m<8k, if the current air outlet temperature of the air conditioner is greater than the first preset temperature range, that is, if the current air outlet temperature of the air conditioner is in the red zone, then the first condensation water area and the air outlet temperature can be cooled according to the second cooling strategy, and the air volume can be adjusted.

[0064] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the second cooling treatment method provided in the embodiment of the present application. Figure 6 The yellow, red and green areas in the Figure 5 The same as in .

[0065] For example, if the current air outlet temperature of the air conditioner is in the red zone, reverse Z-type cooling control can be performed. When the ambient temperature is in the red area to the right of the air conditioning condensation line, it means that the current environment in the car is in a high temperature and high humidity situation. At this time, the air outlet temperature of the car air conditioner can be controlled to be the highest temperature and maximum air volume in the cooling mode, that is, the air outlet temperature and air volume can be increased to reduce the ambient temperature to the nearest air conditioning condensation line. The subsequent cooling process is the same as the first cooling strategy. Afterwards, the air outlet temperature of the car air conditioner in the second process can be controlled to be the same as the current ambient temperature in the car. Then, the cooling temperature in the first condensation water area can be gradually lowered to reduce the humidity of the hot and humid air in the car until the moisture in the air in the car is reduced by the cooling treatment method in the first process. After the humidity is reduced to an appropriate value, the air outlet temperature of the air conditioner is lowered, so that the ambient temperature in the car can be reduced to the green zone. Reference Figure 6 It can be seen that the cooling process of the above-mentioned second cooling strategy looks like an inverted Z-type. Therefore, the second cooling strategy can also be called an inverted Z-type cooling control, which reduces the generation of condensed water in the first process, thereby reducing the failure of electrical components due to condensed water, and at the same time improves the user's riding experience.

[0066] S103: When the condensed water mass is not less than a preset threshold and the humidity outside the vehicle is greater than the humidity inside the vehicle, if the air outlet temperature is within a first preset temperature range, adjust the air outlet temperature and air volume according to a third cooling strategy.

[0067] As an example, after calculating the condensate mass of the entire vehicle based on various parameters in the vehicle air conditioning cooling environment, if m >= 8K and the humidity outside the vehicle is greater than the humidity inside the vehicle, and the air conditioner's outlet air temperature is within the first preset temperature range (i.e., the outlet air temperature is in the yellow zone), the outlet air temperature and air volume can be adjusted according to the third cooling strategy. For example, the air conditioner's outlet air temperature can be controlled to the highest temperature in cooling mode. This is because an increase in outlet air temperature may not meet the user's cooling needs, and the cooling process to reduce condensate will produce condensate first, followed by cooling, resulting in a slower cooling rate. Therefore, to compensate for the slow cooling and the resulting decrease in perceived temperature comfort caused by the inability to meet the user's cooling needs due to the heating, the air conditioner can be controlled to increase air volume during the cooling process based on the empirical formula for perceived temperature to ensure a comfortable perceived temperature. The empirical formula for perceived temperature can be: perceived temperature = ambient temperature - wind speed * wind cooling coefficient + humidity * humidity heat coefficient.

[0068] Therefore, according to the third cooling strategy, the process of adjusting the air outlet temperature and air volume can include raising the air outlet temperature in the cooling mode and increasing the air volume to meet the user's cooling needs. In this way, not only can the user's cooling needs be met, but condensation water can also be reduced, thereby improving the user's riding experience.

[0069] S104: When the condensed water mass is not less than a preset threshold and the humidity outside the vehicle is greater than the humidity inside the vehicle, if the air outlet temperature is greater than a first preset temperature range, adjust the air outlet temperature and air volume according to a fourth cooling strategy.

[0070] As an example, after the condensation water quality of the entire vehicle is calculated based on various parameters in the automobile air-conditioning refrigeration environment, when m>=8k, and the humidity outside the vehicle is greater than the humidity inside the vehicle, if the air outlet temperature of the air conditioner is greater than the first preset temperature range, that is, the air outlet temperature is in the red zone, then the air outlet temperature and air volume can be adjusted according to the fourth cooling strategy. For example, the air outlet temperature of the automobile air conditioner can be controlled to be the highest temperature under the cooling model, that is, the air outlet temperature in the cooling mode can be increased and the air volume can be increased. In addition, a prompt message can be sent to the automobile terminal, which is used to instruct the closing of the doors and windows. Since the use of commercial vehicles is more complicated, it is very likely that the driver will often open the doors and windows, and according to the calculation formula for the quality of condensation water, it can be known that the opening time of the doors and windows is proportional to the quality of condensation water. The quality of condensation water can be determined based on the opening time of the doors and windows. In this way, the overall cooling process can be referred to. Figure 7 , Figure 7 This is an overall schematic diagram of the cooling treatment method provided in an embodiment of the present application.

[0071] S105: When the mass of the condensed water is not less than the preset threshold and the humidity outside the vehicle is less than the humidity inside the vehicle, a cooling process is performed according to the state when the mass of the condensed water is less than the preset threshold.

[0072] As an example, after the condensation water mass of the entire vehicle is calculated based on various parameters in the automobile air-conditioning refrigeration environment, when m>=8k and the humidity outside the vehicle is lower than the humidity inside the vehicle, the cooling process can refer to the first cooling strategy and the second cooling strategy, that is, if the current air outlet temperature of the air conditioner is in the yellow zone, then the cooling temperature in the first condensation water area is lowered, and then the air outlet temperature is lowered to reduce the ambient temperature inside the vehicle to the green zone; if the current air outlet temperature of the air conditioner is in the red zone, then the air outlet temperature and air volume in the cooling mode are increased, and then the cooling temperature in the first condensation water area is lowered, and then the air outlet temperature is lowered to reduce the ambient temperature inside the vehicle to the green zone.

[0073] The above is a condensation water control method provided by an embodiment of the present application. In this method, when the condensation water quality of the whole vehicle is less than a preset threshold value, if the current air outlet temperature of the air conditioner is within a first temperature range that will produce condensation water, the first condensation water area and the air outlet temperature of the air conditioner can be cooled according to the first cooling strategy, thereby reducing the ambient temperature in the vehicle to a second temperature range where condensation water will not be produced; when the condensation water quality of the whole vehicle is less than the preset threshold value, if the current air outlet temperature of the air conditioner is greater than the first preset temperature range, indicating that the current air outlet temperature of the air conditioner is within a temperature range where a large amount of condensation water will be produced, the first condensation water area and the air outlet temperature of the air conditioner can be cooled according to the second cooling strategy, and the air volume of the air conditioner can be adjusted, thereby reducing the ambient temperature in the vehicle to a second temperature range where condensation water will not be produced; when the condensation water quality of the whole vehicle is not less than the preset threshold value, and the humidity outside the vehicle is greater than the humidity inside the vehicle, if the current air outlet temperature of the air conditioner is within the first temperature range where condensation water will be produced, then the third cooling strategy can be used, The air outlet temperature and air volume of the air conditioner are adjusted to reduce the ambient temperature in the vehicle to a second temperature range where condensation water will not be generated; when the condensation water quality of the entire vehicle is not less than the preset threshold value, and the humidity outside the vehicle is greater than the humidity inside the vehicle, if the current air outlet temperature of the air conditioner is greater than the first preset temperature range, it means that the current air outlet temperature of the air conditioner is within the temperature range that will generate a large amount of condensation water, then the air outlet temperature and air volume of the air conditioner can be adjusted according to the fourth cooling strategy to reduce the ambient temperature in the vehicle to a second temperature range where condensation water will not be generated; when the condensation water quality of the entire vehicle is not less than the preset threshold value, and the humidity outside the vehicle is less than the humidity inside the vehicle, cooling treatment can be performed according to the state when the condensation water quality of the entire vehicle is less than the preset threshold value, that is, the current air outlet temperature of the air conditioner can be judged. If the current air outlet temperature of the air conditioner is within the first preset temperature range, cooling treatment can be performed according to the first cooling strategy. If the current air outlet temperature of the air conditioner is greater than the first preset temperature range, the ambient temperature in the vehicle is reduced to a second temperature range where condensation water will not be generated. It can be seen that the embodiments of the present application provide cooling strategies for different situations. Through the above-mentioned cooling strategies, the ambient temperature in the car can be reduced to a temperature range where no condensation water will be generated, thereby reducing the condensation water generated during the operation of the car air conditioner, thereby reducing the failure of electrical components due to condensation water, and improving the user's riding experience.

[0074] The above are some specific implementations of the condensate water control method provided in the embodiments of the present application.
