Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an air conditioning system, a dehumidification method, and a drying device. Background Art

[0002] With the development of automobile technology, people's requirements for the comfort of the whole vehicle are getting higher and higher. As one of the mainstream configurations of automobiles, the air conditioning system (heating ventilation and air conditioning, HVAC) (can be referred to as air conditioning for short) can provide a comfortable riding environment for drivers and passengers. However, traditional car air conditioners have the problem of high energy consumption during use, which will lead to a decrease in vehicle energy efficiency. For example, in the scene of heating in the car in winter, if the humidity in the car is high, in order to prevent fogging in the car, the car air conditioner usually introduces dry fresh air from outside the car into the car, and heats the air in the car and the dry fresh air to the target temperature to achieve the purpose of dehumidification in the car. However, due to the low temperature of the dry fresh air, it takes more energy to heat the dry fresh air to the target temperature, which will increase the energy consumption of the car air conditioner.

[0003] Therefore, how to reduce the energy consumption of vehicle air conditioners has become an urgent problem that needs to be solved in the industry. Summary of the invention

[0004] The present application provides an air conditioning system, a dehumidification method, and a drying device to reduce the energy consumption of a vehicle air conditioner, thereby improving the energy efficiency of the vehicle.

[0005] In a first aspect, an embodiment of the present application provides an air-conditioning system, which includes a controller, a drying device and an air-conditioning device; wherein a accommodating cavity formed by a shell of the drying device is filled with a desiccant; the controller is used to determine whether the desiccant is saturated when the vehicle meets the dehumidification conditions; the controller is also used to control the opening and closing structure of the drying device to open when the desiccant is not saturated, so that the desiccant absorbs moisture in the air inside the vehicle; and control the air-conditioning to heat and dehumidify the air inside the vehicle.

[0006] The air conditioning system in the embodiment of the present application can absorb moisture in the air inside the vehicle through the desiccant in the air conditioning system when the vehicle meets the dehumidification conditions, and control the air conditioning to heat and dehumidify the air inside the vehicle. In this way, during the entire dehumidification process, the air conditioning does not need to heat the dry fresh air outside the vehicle, which can effectively reduce the power consumption of the air conditioning, thereby effectively improving the energy efficiency of the vehicle.

[0007] In a possible design, the controller is also used to: when the desiccant is saturated and the vehicle is in a locked state and / or there is no user in the vehicle, control the heating element in the drying device to heat and reduce the desiccant. In this design, when the desiccant in the drying device can be heated and reduced, the controller in the air conditioning system can also control the heating element in the drying device to heat and reduce the desiccant, so that the desiccant in the drying device can be recycled, effectively saving energy; and the heating and reduction process of the desiccant is carried out when the vehicle is in a locked state and / or there is no user in the vehicle, so that the user does not feel the heating and reduction process of the desiccant, and thus does not affect the user's riding experience.

[0010] In a possible design, the controller is further used to: when the desiccant is saturated, control the prompt device to output a first prompt message, and the first prompt message is used to instruct to replace the desiccant in the desiccant device. In this design, after the desiccant in the desiccant device is saturated, a prompt message instructing to replace the desiccant can be output, so that the desiccant can be replaced in time, and then the new desiccant can absorb the moisture in the car, so that the dehumidification process in the car can continue.

[0059] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Reference to "one embodiment" or "some embodiments" described in this specification means that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in the different parts of this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. In addition, the words "first", "second", etc. involved in this specification are only used to distinguish the purpose of description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order.

[0060] First, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0061] 1. In internal circulation mode, the air conditioner heats the air inside the car to achieve dehumidification.

[0062] 2. In external circulation mode, the air conditioner introduces dry fresh air from outside the car and heats the dry fresh air to achieve dehumidification in the car.

[0063] 3. In mixed air mode, the air conditioner heats the air inside the car and the dry fresh air introduced from outside the car to achieve dehumidification in the car.

[0064] 4. Physical adsorption type desiccant, which can remove moisture from the air by physical adsorption. Physical adsorption type desiccant, for example, can be at least one of silica gel desiccant, activated alumina, sodium sulfate, potassium carbonate, or anhydrous copper sulfate. Among them, physical adsorption type desiccant can be heated and reduced to achieve recycling.

[0065] 5. Chemical reaction type desiccants can remove moisture from the air through chemical reactions. Some chemical reaction type desiccants (such as anhydrous calcium chloride) can be reduced by heating, while others can only be reduced by chemical reagents.

[0066] The present application provides an air conditioning system, a dehumidification method, and a drying device to reduce the energy consumption of a vehicle air conditioner, thereby improving the energy efficiency of the vehicle. When the vehicle meets the dehumidification conditions, the desiccant in the air conditioning system can absorb the moisture in the air inside the vehicle, and the air conditioning can be controlled to heat and dehumidify the air inside the vehicle. In this way, during the entire dehumidification process, the air conditioning does not need to heat the dry fresh air outside the vehicle, which can effectively reduce the power consumption of the air conditioning, thereby effectively improving the energy efficiency of the vehicle.

[0067] The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0068] Figure 1 This is a structural schematic diagram of an air-conditioning system provided in an embodiment of the present application. The air-conditioning system includes a controller 100, an air conditioner 200, and a drying device 300.

[0069] The controller 100 may be any chip or integrated circuit with computing capability. For example, the controller 100 may be a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), other programmable logic devices, transistor logic devices, or any combination thereof. The general purpose processor may be a microprocessor, such as a micro controller unit (MCU), or may be other conventional processors.

[0070] The air conditioner 200 is a device with a dehumidification function. For example, Figure 2 A schematic diagram showing a possible structure of the air conditioner 200 is shown. Figure 2 In the figure, the air conditioner 200 includes a heater core, a blower, an air outlet 1, an air outlet 2, and a damper. The heater core is used to provide warm air to the vehicle, and the blower can adjust the air volume of the warm air. The air outlet 1 and the air outlet 2 can independently adjust the temperature and / or air volume, and blow the warm air provided by the heater core to the corresponding position. For example, the air outlet 1 is facing the main driving position, so that the warm air provided by the heater core can be blown to the main driving position; the air outlet 2 is facing the co-pilot position, so that the warm air provided by the heater core can be blown to the co-pilot position.

[0071] like Figure 2 As shown in (a), when the air conditioner 200 is a vehicle-mounted air conditioner, in a vehicle heating scenario (such as a winter heating scenario), when the air conditioner 200 can start external circulation, the air door of the air conditioner 200 is in an open state, and the blower of the air conditioner 200 introduces dry fresh air outside the vehicle into the vehicle through the air inlet, and the warm air core heats the dry fresh air to obtain warm air, which can be blown into the vehicle cabin through the air outlet 1 and the air outlet 2.

[0073] The drying device 300 is a device with a drying function. In a vehicle heating scenario (e.g., a winter heating scenario), the desiccant in the drying device 300 can absorb moisture in the air to achieve dehumidification of the air in the vehicle. The drying device 300 can be arranged in an air circulation area in the vehicle cabin. The air circulation area can be the interior of the air conditioner 200, the air duct of the air conditioner 200, the air outlet of the air conditioner 200, or the air inlet of the air conditioner 200. For example, Figure 2 As shown, the drying device 300 may be disposed between the warm air core of the air conditioner 200 and the blower of the air conditioner 200 (ie, the air duct of the air conditioner 200 ).

[0074] The drying device 300 is described in detail below with reference to specific drawings.

[0076] The housing 301 includes an opening and closing structure 3011. When the opening and closing structure 3011 is opened, a first opening is formed on the housing 301, and the desiccant contacts the air outside the housing 301 through the first opening. The opening and closing structure 3011 can be implemented in a variety of ways, including but not limited to the following implementations:

[0078] Implementation method 2, Figure 4B This is a second schematic diagram of the first surface of the housing 301. Figure 4B In the embodiment, the opening and closing structure 3011 includes a first component and a second component, the first component is provided with a plurality of holes, and the second component is a rotatable component; Figure 4B As shown in (a), when the opening and closing structure 3011 is in the open state, the second component rotates to a position with a first angle with the first component, and the plurality of holes on the first component are not blocked by the second component. At this time, the plurality of holes form a first opening; Figure 4B As shown in (b), when the opening and closing structure 3011 is in a closed state, a number of holes on the first component are blocked by the second component.

[0079] Implementation method 3, Figure 4C The third schematic diagram of the first surface of the housing 301 is shown in FIG. Figure 4C In the embodiment, the opening and closing structure 3011 includes a first component and a second component, the first component is provided with a first hole, and the second component is a rotatable component; Figure 4C As shown in (a), when the opening and closing structure 3011 is in the open state, the second component rotates to a position with a second angle with the first component, and the first hole on the first component is not blocked by the second component. At this time, the first hole forms a first opening; Figure 4C As shown in (b), when the opening and closing structure 3011 is in a closed state, the first stem hole on the first component is blocked by the second component.

[0080] Implementation method 4, Figure 4D The third schematic diagram of the first surface of the housing 301 is shown in FIG. Figure 4D In the embodiment, the opening and closing structure 3011 includes a frame, a first component and a locking mechanism, the first component is retractable, the first component is arranged on a first side of the frame, and the locking mechanism is arranged on a second side of the frame; Figure 4D As shown in (a), when the opening and closing structure 3011 is in the closed state, the first component extends to the second side and closes with the locking mechanism; Figure 4D As shown in (b), when the opening and closing structure 3011 is in the open state, the first component is in the contracted state, and at this time, a first opening is formed on the first surface of the shell 301.

[0081] The heating element 304 is a circuit or element with a heating function. For example, the heating element 304 can be any one of a heating wire, a heating line, a heating tube, or a heating coil.

[0082] Optional, see Figure 5 The drying device 300 may further include a through hole 305, which is disposed on the housing 301. The liquid formed after the desiccant 302 absorbs moisture can be discharged through the through hole 305. In this way, the liquid formed after part of the chemical reaction type desiccant absorbs moisture can be discharged in time, which is convenient for replacing new desiccant in the drying device 300.

[0083] In the embodiment of the present application, the controller 100 can be arranged in the drying device 300 or outside the drying device 300. That is, the controller 100 can be a component in the drying device 300 or a device independent of the drying device 300. When the weight sensor 303 detects the weight of the desiccant 302, the controller 100 can determine whether the desiccant 302 is saturated based on the weight of the desiccant 302; when the desiccant 302 is not saturated, the controller 100 can control the opening and closing structure 3011 to open so that the desiccant 302 absorbs moisture in the air outside the housing 301; or, when the desiccant 302 is saturated, the controller 100 can control the opening and closing structure 3011 to close, and control the heating element 304 to heat and restore the desiccant 302.

[0084] The above-mentioned air conditioning system and drying device can be applied to scenes where air conditioning is provided. For example, it can be applied to scenes such as vehicles or smart homes. Among them, when the air conditioning system or drying device 300 is applied to a vehicle, the controller 100 can be any one of the vehicle domain controller, body domain controller, electronic control unit (ECU), or vehicle-mounted terminal in the vehicle.

[0085] When the drying device 300 is applied to a vehicle, the embodiment of the present application provides a dehumidification method. Figure 6 The execution subject of the method may be the controller 100, and the method includes:

[0086] S601 : The controller 100 controls the opening and closing structure 3011 of the drying device 300 in the vehicle to open, so that the desiccant 302 in the drying device 300 absorbs moisture in the air in the vehicle.

[0087] S602: The controller 100 controls the air conditioner 200 in the vehicle to heat and dehumidify the air in the vehicle.

[0088] exist Figure 6In the method shown, the controller 100 achieves the purpose of dehumidification by controlling the desiccant 302 in the drying device to absorb moisture in the air in the vehicle, and starts the air conditioner to heat and dehumidify the air in the vehicle. In this way, during the entire dehumidification process, the vehicle air conditioner does not need to start the external circulation, that is, the air conditioner does not need to introduce dry fresh air outside the vehicle, nor does it need to heat the dry fresh air, which can effectively reduce the power consumption of the vehicle air conditioner, thereby improving the energy efficiency of the vehicle.

[0089] As can be seen from the above description, after the controller 100 controls the opening and closing structure 3011 of the drying device 300 in the vehicle to open, a first opening is formed on the housing 301 of the drying device 300, and then the desiccant 302 absorbs moisture in the air in the vehicle through the first opening. Combining the various implementations of the above-mentioned opening and closing structure 3011, it can be seen that the controller 100 controls the opening and closing structure 3011 to open in the following embodiments, but is not limited to:

[0090] Implementation method 1, for Figure 4A In the opening and closing structure 3011 , the controller 100 can control the contraction state of the first component and the second component, the first component contracts to the first side of the frame, and the second component contracts to the second side of the frame, forming a first opening on the first surface of the shell 301 .

[0091] Implementation method 2, for Figure 4B In the opening and closing structure 3011, the controller 100 can control the second component to rotate so that the second component and the first component are at a first angle. At this time, several holes on the first component are not blocked by the second component, and the several holes form a first opening.

[0092] Implementation method 3, for Figure 4C In the opening and closing structure 3011, the controller 100 can control the second component to rotate so that the second component and the first component are at a second angle. At this time, the first hole on the first component is not blocked by the second component, and the first hole forms a first opening.

[0093] Implementation method 4, for Figure 4D In the opening and closing structure 3011 , the controller 100 can control the first component to be in a contracted state, and the first component contracts to the first side of the frame, and at this time a first opening is formed on the shell 301 .

[0094] In the embodiment of the present application, the desiccant 302 may be a physical adsorption type desiccant or a chemical reaction type desiccant. Different types of desiccant have different treatment methods after the desiccant is saturated.

[0095] In a possible implementation, if the desiccant 302 is a physical adsorption type desiccant, when the desiccant 302 is saturated, the controller 100 can control the heating element 304 to heat and reduce the desiccant 302; and the condensed water formed after the desiccant 302 is heated and reduced is discharged through the through hole 305. Optionally, when the desiccant 302 is a physical adsorption type desiccant, the heating temperature of the heating element 304 is less than 100 degrees Celsius. The physical adsorption type desiccant can be, for example, at least one of a silica gel desiccant, activated alumina, sodium sulfate, potassium carbonate, or anhydrous copper sulfate. In this way, by heating and reducing the physical adsorption type desiccant, the physical adsorption type desiccant can be recycled.

[0096] In another possible implementation, if the desiccant 302 is a chemical reaction type desiccant, when the desiccant 302 is saturated, the controller 100 can control the heating element 304 to heat and reduce the desiccant 302; and the condensed water formed after the desiccant 302 is heated and reduced is discharged through the through hole 305. Optionally, when the desiccant 302 is a chemical reaction type desiccant, the heating temperature of the heating element 304 is greater than 100 degrees Celsius. Exemplarily, such a chemical reaction type desiccant can be, for example, anhydrous calcium chloride. After the anhydrous calcium chloride absorbs water, the heating element 304 can reduce the anhydrous calcium chloride by heating the temperature of the anhydrous calcium chloride to 150 degrees.

[0097] In another possible implementation, if the desiccant 302 is a chemical reaction type desiccant, when the desiccant 302 is saturated, the desiccant 302 will chemically react with the water absorbed by it and form a corresponding liquid, which can be discharged through the hole 305. At this time, a new desiccant can be placed in the drying device 300. Exemplarily, such a chemical reaction type desiccant can be any one of silica gel, calcium chloride (such as anhydrous calcium chloride), calcium oxide (quicklime), and potassium permanganate.

[0098] When the above air conditioning system is applied to a vehicle, the present application embodiment provides another dehumidification method. Figure 7 The execution subject of the method is the controller 100 in the air conditioning system, and the method includes:

[0099] S701. When the vehicle meets the dehumidification conditions, the controller 100 determines whether the desiccant 302 is saturated.

[0100] In the embodiment of the present application, the dehumidification condition may include one or more of the following: the humidity inside the vehicle is greater than a first threshold, the temperature inside the vehicle is greater than a second threshold, and the temperature outside the vehicle is less than a third threshold. The specific values ​​of the first threshold, the second threshold, and the third threshold may be the same or different.

[0101] For example, the first threshold is 60%. In the winter car heating scenario, when the vehicle is heated by air conditioning 200, if the humidity in the vehicle is greater than 60%, it is considered that the vehicle meets the dehumidification conditions. At this time, the windows may fog up and the air in the vehicle needs to be dehumidified.

[0102] For another example, the first threshold is 60% and the second threshold is 25. In the scenario of car heating in winter, when the vehicle is heated by air conditioning 200, if the humidity in the car is greater than 60% and the temperature in the car is greater than 25°C, it is considered that the vehicle meets the dehumidification conditions. At this time, there is a possibility that the windows are fogged and the air in the car needs to be dehumidified.

[0103] For another example, the first threshold is 60%, the second threshold is 25, and the third threshold is 10. In the scenario of car heating in winter, when the vehicle is heated by air conditioning 200, if the humidity in the car is greater than 60%, the temperature in the car is greater than 25°C, and the temperature outside the car is less than 10°C, then the vehicle is considered to meet the dehumidification conditions. At this time, there is a possibility that the windows are fogged and the air in the car needs to be dehumidified.

[0104] In a possible implementation of S701, the controller 100 can determine whether the desiccant 302 is saturated by the weight of the desiccant 302. Specifically, the controller 100 can receive the weight information detected by the weight sensor 303 in real time, and determine whether the desiccant 302 is saturated according to the weight information. For example, the relationship between the weight of the desiccant 302 and the saturation degree of the desiccant 302 is shown in Table 1. In Table 1, the initial weight of the desiccant 302 (i.e., the weight of the desiccant 302 when it does not absorb moisture) is 100g, at which time the desiccant 302 is not saturated, and the desiccant can absorb 400g of moisture; the weight of the desiccant 302 at time T1 is 200g, at which time the desiccant 302 is not saturated, and the desiccant can also absorb 300g of moisture; the weight of the desiccant 302 at time T2 is 500g, at which time the desiccant 302 is saturated and can no longer absorb moisture. Accordingly, the controller 100 can determine whether the desiccant 302 is saturated and the saturation degree of the desiccant 302 according to Table 1.

[0105] Table 1

[0106]

[0107] S702: If the desiccant 302 is not saturated, the controller 100 controls the opening and closing structure 3011 of the drying device 300 to open, so that the desiccant 302 absorbs moisture in the air inside the vehicle.

[0108] Among them, the implementation method of the controller 100 controlling the opening and closing structure 3011 to open can be found in the relevant description above and will not be repeated here.

[0109] For example, Fig. 8A As shown, when the desiccant 302 is not saturated, the controller 100 controls the opening and closing structure 3011 of the drying device 300 to open, and the shell of the drying device 300 forms a first opening; the controller 100 controls the blower in the air conditioner 200 to blow the humid air in the car into the drying device 300, so that the desiccant 302 absorbs moisture in the humid air, and the humid air can form dry air after passing through the drying device 300.

[0110] S703: If the desiccant 302 is not saturated, the controller 100 controls the air conditioner 200 to heat and dehumidify the air in the vehicle.

[0111] For example, please see Fig. 8A As shown, when the desiccant 302 is not saturated, the controller 100 can control the air conditioner 200 to start the internal circulation mode, so that the air conditioner 200 heats the air inside the vehicle, so that the temperature of the air inside the vehicle is greater than the target temperature, thereby achieving heating and dehumidification of the air inside the vehicle.

[0112] In S702 and S703, the desiccant 302 absorbs moisture from part of the air in the vehicle, and the air conditioner 200 heats and dehumidifies the other part of the air in the vehicle, thereby achieving dehumidification of the air in the vehicle. In this way, during the entire dehumidification process, the air conditioner 200 does not need to turn on the external circulation mode, that is, the air conditioner 200 does not need to heat the dry fresh air outside the vehicle, which can effectively reduce the power consumption of the air conditioner 200, thereby improving the energy efficiency of the vehicle.

[0113] Optional, such as Figure 8B As shown, if the vehicle meets the dehumidification conditions, the desiccant 302 is saturated, and the drying device 300 cannot work at this time, the controller 100 can control the air conditioner 200 to turn on the mixed air mode, the controller 100 controls the air conditioner 200 to turn on the internal circulation mode, and the air conditioner 200 heats the air in the vehicle to the target temperature, and the air conditioner 200 can turn on the external circulation mode to introduce a small amount of dry fresh air outside the vehicle and heat the dry fresh air to the target temperature. In this way, the vehicle can be dehumidified through the internal circulation mode and the external circulation mode of the air conditioner.

[0114] As can be seen from the above, the desiccant 302 can be a physical adsorption type desiccant or a chemical reaction type desiccant. Different types of desiccant have different treatment methods. The following is an introduction of heatable desiccant and non-heatable desiccant.

[0115] 1. Heatable reducible desiccant, including physical adsorption type desiccant and some chemical reaction type desiccant. Among them, the physical adsorption type desiccant can be, for example, at least one of silica gel desiccant, activated alumina, sodium sulfate, potassium carbonate, or anhydrous copper sulfate. The some chemical reaction type desiccant can be, for example, anhydrous calcium chloride. Optionally, when the desiccant 302 is a physical adsorption type desiccant, the heating temperature of the heating element 304 is less than 100 degrees Celsius; when the desiccant 302 is the some chemical reaction type desiccant, the heating temperature of the heating element 304 is greater than 100 degrees Celsius.

[0116] If the desiccant 302 is a heatable desiccant, when the desiccant 302 is saturated, the controller 100 can control the heating element 304 in the drying device 300 to heat and reduce the desiccant so that the drying device 300 can continue to work. Fig. 9 As shown, the process of the controller 100 controlling the heating element 304 to heat and reduce the desiccant 302 includes:

[0117] S901. The controller 100 determines whether the vehicle satisfies a first condition.

[0118] The first condition may include, but is not limited to, at least one of: the vehicle is in a locked state, there is no user in the vehicle, or the vehicle is in a charging state. For example, the first condition may be that the vehicle is in a locked state. For another example, the first condition may be that the vehicle is in a locked state and there is no user in the vehicle. For another example, the first condition may be that the vehicle is in a charging state and there is no user in the vehicle. For another example, the first condition may be that the vehicle is in a locked state and a charging state, and there is no user in the vehicle.

[0119] Specifically, when the vehicle meets the first condition, the controller executes S902; when the vehicle does not meet the first condition, the subsequent process is stopped.

[0120] S902 , the controller 100 determines whether the desiccant 302 is saturated.

[0121] Specifically, when the desiccant 302 is saturated, the controller 100 executes S903 .

[0122] S903 , the controller 100 controls the heating element 304 to heat and reduce the desiccant 302 .

[0123] In S901-S903, the heating and restoring process of the desiccant 302 is performed when the vehicle meets the first condition (i.e., the vehicle is locked, the vehicle is charging, or there is no user in the vehicle), so that the user does not feel the heating and restoring process of the desiccant 302, and thus does not affect the user's riding experience. In addition, by heating and restoring the desiccant 302, the desiccant 302 can be recycled, effectively saving energy.

[0124] Optionally, when the vehicle is in a charging state, the controller 100 may also control the heating element 304 to heat and reduce the desiccant 302 under the power supply of the charging pile. In this way, by using the charging pile to power the heating element 304, the heating and reducing process of the desiccant 302 does not consume the power of the vehicle, which can further improve the energy efficiency of the vehicle.

[0125] S904: The controller 100 turns on the external circulation mode of the air conditioner.

[0126] S905 : The controller 100 turns on the blower in the air conditioner.

[0127] In the embodiment of the present application, when the desiccant 302 is saturated, the desiccant 302 is heated and reduced by the heating element 304 to form moisture; Fig.10 As shown, the controller 100 can control the air conditioner 200 to start the external circulation mode, and introduce dry fresh air (i.e., dry air) outside the vehicle; at this time, the opening and closing structure 3011 of the drying device 300 is in the open state, and the controller 100 can control the blower to blow dry air into the drying device 300, and the dry air absorbs the moisture formed after the desiccant 302 is heated and reduced to form humid air, which can be discharged through the air outlet of the air conditioner 200. In this way, it can effectively avoid the situation where the moisture formed after the desiccant 302 is heated and reduced is retained in the air conditioner 200 or the vehicle cabin and increases the humidity in the vehicle.

[0128] 2. Non-heatable reducible desiccants include some chemical reaction type desiccants, which may be any one of silica gel, calcium chloride (such as anhydrous calcium chloride), calcium oxide (quicklime), and potassium permanganate.

[0129] If the desiccant 302 is a non-heatable desiccant, the desiccant 302 will form a liquid after absorbing moisture in the air in the vehicle. When the above air conditioning system is applied to a vehicle, the through hole 305 in the drying device 300 can be connected to the drain pipe of the air conditioner 200. Accordingly, the liquid formed by the desiccant 302 after absorbing moisture in the air in the vehicle can be discharged to the outside of the vehicle through the through hole 305 and the drain pipe in sequence. In this way, the liquid formed by the desiccant 302 can be discharged in time, which facilitates the timely replacement of the desiccant in the drying device 300.

[0130] Accordingly, after the liquid formed by the desiccant 302 is discharged outside the drying device 300, the controller 100 can also control the prompt device to output a first prompt message, and the first prompt message is used to indicate the replacement of the desiccant in the drying device 300. In this way, the desiccant 302 can be replaced in time, and then the new desiccant can continue to absorb moisture from the air in the vehicle, so that the dehumidification process in the vehicle can continue. Among them, the prompt device may include but is not limited to at least one of a voice device, an optoelectronic device, or a display device. Exemplarily, the prompt device 200 can be, for example, at least one of a vehicle-mounted display screen, a tablet computer, a laptop computer, a PDA, headphones, speakers, wearable devices (such as smart watches, smart bracelets, pedometers, etc.), virtual reality (VR) devices, or mobile phones. Accordingly, the "first prompt message" output by the prompt device 200 can be at least one of a voice message, a text message, or a picture message. For example, the controller 100 can control the prompt device to display on the vehicle-mounted display screen such as Fig.11 The first prompt message shown is "Please replace the desiccant!".

[0131] Based on the structure and functional principles of the air-conditioning system described above, the present application may also provide a vehicle, which may include the above-mentioned air-conditioning system or drying device. Fig.12 12 is an exemplary functional block diagram of a vehicle provided in the present application. Components coupled to or included in the vehicle 1200 may include an air conditioning system 1201 and a control system 1202. It is understood that Fig.12The vehicle functional framework given is just an example. In other examples, the vehicle 1200 may include more, fewer or different systems, and each system may include more, fewer or different components. In addition, the systems and components shown may be combined or divided in any manner, and this application does not specifically limit this. For example, the vehicle may also include a power supply 1203, a sensor system 1204, a user interface 1205, and a peripheral device 1206. In some embodiments, the peripheral device 1206 provides a means for the user of the vehicle 1200 to interact with the user interface 1205. For example, the touch screen may provide information to the user of the vehicle 1200, such as displaying automatic driving and manual driving modes for the driver to select. The user interface 1205 may also operate the touch screen to receive the user's input, such as inputting or selecting automatic driving or manual driving modes. In other cases, the peripheral device 1206 may provide a means for the vehicle 1200 to communicate with other devices located in the vehicle. For example, a microphone may receive audio (e.g., voice commands or other audio input) from a user of the vehicle 1200. Similarly, a speaker may output audio to a user of the vehicle 1200. The components of the vehicle 1200 may be configured to work in a manner interconnected with each other and / or with other components coupled to various systems. For example, the power supply 1203 may provide power to all components of the vehicle 1200. The control system 1202 may be configured to receive data from the air conditioning system 1201, the sensor system 1204, and the peripheral device 1206 and control them.

[0132] The air conditioning system 1201 can refer to the introduction of any of the above embodiments, which will not be repeated here.

[0133] The sensor system 1204 may include several sensors for sensing information about the environment in which the vehicle 1200 is located. Exemplarily, the sensor system 1204 may include a temperature and humidity sensor for collecting temperature and humidity information inside and outside the vehicle. Further, the sensors of the sensor system 1204 may also include, but are not limited to, millimeter wave radar, laser radar, visual device, global positioning system (global positioning system, GPS), inertial measurement unit (inertial measurement unit, IMU), and brakes for modifying the position and / or orientation of the sensor. In some embodiments, GPS may be any sensor for estimating the geographic location of the vehicle 1200. To this end, the GPS may include a transceiver to estimate the position of the vehicle 1200 relative to the earth based on satellite positioning data. In some examples, the control system 1202 may determine whether the vehicle needs dehumidification in combination with the temperature and humidity information collected by the temperature and humidity sensor.

[0134] It is understood that the sensor system 1204 may also include sensors of the internal systems of the monitored vehicle 1200 (e.g., in-vehicle air quality monitor, fuel gauge, oil temperature gauge, accelerator pedal position sensor, etc.). Sensor data from one or more of these sensors can be used to detect objects and their corresponding characteristics (position, shape, direction, speed, etc.). Such detection and identification is a key function for the safe operation of the vehicle 1200. The sensor system 1204 may also include other sensors. This application does not specifically limit this.

[0135] Some or all functions of the vehicle 1200 are controlled by a control system 1202. The control system 1202 may include at least one processor 12021, and further, the control system 1202 may include an interface circuit 12022. The processor 12021 executes instructions stored in a non-transitory computer-readable medium such as a memory 12023. The control system 1202 may also be a plurality of computing devices that control individual components or subsystems of the vehicle 1200 in a distributed manner.

[0136] Processor 12021 can be a circuit with signal (or data) processing capability. In one implementation, the processor can be a circuit with instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP); in another implementation, the processor can implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or reconfigurable, such as a hardware circuit implemented by a processor as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. For example, it can also be an application processor (AP), an image signal processor (ISP), or other programmable logic devices, transistor logic devices, hardware components or any combination thereof.

[0137] although Fig.12 The processor, memory, and other elements of the control system 1202 are functionally illustrated in the same block, but one of ordinary skill in the art will appreciate that the processor and memory may not actually be multiple processors or memories stored in the same physical housing. For example, the memory may be a hard drive or other storage medium located in a different housing than the control system 1202. For another example, the processor may be remote from the vehicle but may be in wireless communication with the vehicle.

[0138] In some embodiments, the memory 12023 may include instructions (e.g., program logic) that can be read by the processor 12021 to perform various functions of the vehicle 1200, including the functions described above. The memory 12023 may also include additional instructions, including instructions to send data to, receive data from, interact with, and / or control one or more of the sensor system 1204, the control system 1202, and the peripheral device 1206. In addition to instructions, the memory 12023 may also store data, such as road maps, route information, data detected by sensors, the location, direction, speed, and other such vehicle data of the vehicle, as well as other information. This information can be used by the vehicle 1200 and the control system 1202 in the vehicle 1200 in autonomous, semi-autonomous, and / or manual modes.

[0139] The memory may be, for example, a random access memory (RAM), a flash memory, a read-only memory (ROM), a programmable ROM (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a register, a hard disk, a mobile hard disk, a CD-ROM, or any other form of storage medium known in the art. An exemplary storage medium is coupled to a processor so that the processor can read information from the storage medium and write information to the storage medium. In another example, the storage medium may also be a component of the processor. The processor and the storage medium may be located in an ASIC. In addition, the ASIC may be located in a control system. Of course, the processor and the storage medium may also exist in a control system as discrete components.

[0140] The control system 1202 may control functions of the vehicle 1200 based on input received from various subsystems (e.g., sensor system 1204, etc.) and from the user interface 1205. For example, the control system 1202 may utilize input from the sensor system 1204 to control the vehicle to accelerate or decelerate to avoid an obstacle detected by an obstacle avoidance system. In some embodiments, the control system 1202 may be operable to provide control over many aspects of the vehicle 1200 and its subsystems.

[0141] Alternatively, one or more of the above-mentioned components may be installed or associated separately from the vehicle 1200. For example, the memory 12023 may exist partially or completely separately from the vehicle 1200. The above-mentioned components may be communicatively coupled together in a wired and / or wireless manner.

[0142] Exemplarily, the vehicle 1200 may be a pure electric vehicle, a hybrid electric vehicle, an extended-range electric vehicle, a plug-in hybrid electric vehicle, other new energy vehicles or a fuel vehicle, etc.

Therefore, the present application may adopt the form of a complete hardware embodiment, a complete software embodiment, or an embodiment in combination with software and hardware. Moreover, the present application may adopt the form of a computer program product implemented in one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) that include computer-usable program code.

It should be understood that each process and / or box in the flowchart and / or block diagram, as well as the combination of the processes and / or boxes in the flowchart and / or block diagram, can be implemented by computer program instructions.
