Description

Technical Field

[0002] Currently, fragrance systems integrated with vehicle air conditioning systems are limited by the AC's operating state, releasing fragrance only when it's on and in face-blowing mode. A few fragrance systems operate independently of the AC system and can be turned on and off independently, but these systems require separate air ducts and outlets. Furthermore, some fragrance systems lack precise adjustment, resulting in varying degrees of intensity and subtlety in different environments, which can significantly impact the driver's mood.

[0025] For the purposes of brevity and illustration, the principles of the present application are described herein primarily with reference to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of air conditioning methods and systems, vehicles, and storage media, and that the same or similar principles may be implemented therein, without departing from the true spirit and scope of the present application.

[0026] It should be noted that the air conditioning system in some examples of the present invention refers to a system including temperature regulation function and odor regulation function. In some examples, it only refers to the unit module in the air conditioning system that realizes the temperature regulation function, which is also referred to as the air conditioning system.

[0027] The context of the present invention records setting the air volume of the odor adjustment unit, which can be achieved specifically by adjusting the fan speed of the odor adjustment unit.

[0028] According to one aspect of the present application, there is provided an air conditioning method for a vehicle. Figure 1 As shown, the air conditioning method 10 includes the following process. Figure 1 A feasible sequence is shown in FIG, but the present invention is not limited thereto. In other examples, Figure 1 The order of the various steps shown in FIG. 1 can be reversed. Air conditioning method 10 determines the ambient temperature inside the vehicle in step S102, determines the operating state of the temperature control unit and the minimum air volume of the odor control unit under the operating state in step S104, receives the concentration setting of the odor control unit in step S106, and determines the air volume of the odor control unit in step S108 based on the ambient temperature determined in step S102, the operating state and minimum air volume determined in step S104, and the concentration setting received in step S106. The following examples will use fragrance as an example to illustrate the basic principles of air conditioning method 10. Through these steps of air conditioning method 10, the release of odors such as fragrance can be precisely controlled to achieve air purification.

[0029] In step S102, the air conditioning method 10 determines the ambient temperature inside the vehicle. According to the kinetic theory of molecules, the movement and diffusion of fragrance molecules are related to temperature. Therefore, the number of fragrance molecules perceived by the human olfactory system (the intensity of the scent) is also related to the ambient temperature. Therefore, the ambient temperature can be detected first, and then the method for releasing the fragrance can be determined based at least in part on the detected temperature.

[0030] In step S104, the air conditioning method 10 determines the operating status of the temperature control unit. Because the temperature control unit (e.g., the vehicle air conditioning system) shares an air duct with the aroma control unit (e.g., the fragrance system) described below, the operating status of the temperature control unit (e.g., whether it is on, the operating position, the fan speed, etc.) will affect the operation of the aroma control unit. In some examples of the present invention, the method for releasing fragrance can be determined at least in part based on the operating status of the temperature control unit.

[0031] Figure 3An example of a temperature adjustment unit and an odor adjustment unit sharing an air duct is shown. As shown in the figure, the air conditioning system 302 and the fragrance system 304 share an air duct 306. The air flow from the air conditioning system 302 passes through the first air duct 321, and the air flow from the fragrance system 304 passes through the second air duct 341, and then the two air flows merge into the air duct 306. It is worth noting that when the air conditioning system 302 is working, the pressure generated at the outlet of the first air duct 321 may be greater than the pressure at the outlet of the second air duct 341, so the air flow from the second air duct 341 will be significantly affected by the air flow from the first air duct 321. That is, the air conditioning system 302 will affect the operation of the fragrance system 304 to a certain extent. In some examples of the present invention, the working status of the temperature adjustment unit can be determined first, and then the working mode of the fragrance system can be configured at least in part based on its working status.

[0032] In some examples, the minimum air volume of the odor adjustment unit can be determined based on the operating status of the temperature adjustment unit. Figure 6 As shown, air conditioning system 302 and fragrance system 304 are simultaneously activated. Specifically, damper 322 of air conditioning system 302 remains open, and fan 343 of fragrance system 304 is also on. To ensure that the fragrance in fragrance system 304 can be rapidly and controlled diffused across all air conditioning system 302 and air outlet settings, and to prevent adverse effects such as unintended backflow, fan 343 must maintain a minimum airflow output.

[0033] The following table illustrates the minimum speed requirements for fan 343 of fragrance system 304 to ensure fragrance can be dispensed under different operating conditions of air conditioning system 302 for a specific vehicle model. The speed of fan 343 of fragrance system 304 must be adjusted to ensure that the outlet of second air duct 341 of fragrance system 304 can overcome the corresponding back pressure.

[0034] Air conditioning system operating conditions Air volume of air conditioning system under different working conditions (CMH) The back pressure that the fragrance system fan must overcome at its minimum speed (Pa) 1 89.46 10.02 2 122.29 18.73 3 153.48 29.50 4 188.77 44.63 5 229.81 66.15 6 283.16 100.42 7 350.22 153.62 8 435.00 237.00

[0035] To this end, the speed of the fan 343 of the fragrance system 304 can be matched to the operating state of the air conditioning system 302 (e.g., its fan gear position) to ensure that backflow does not occur, preventing the fragrance from being blown out. The flow rate generated by the speed required to overcome back pressure and ensure the fragrance is blown out is called the minimum air volume, which is related to the operating state of the temperature control unit (e.g., the operating conditions in the table above). The following table shows an example of the minimum air volume setting determined based on the operating state of the temperature control unit.

[0036] Air conditioning system operating conditions Minimum air volume of the fragrance system 1 M1 2 M2 3 M3 4 M4 5 M5 6 M6 7 M7 8 M8

[0037] In step S106, the air conditioning method 10 receives a setting for the concentration level of the odor adjustment unit. The setting for the concentration level of the odor adjustment unit may include whether to enable or disable the odor adjustment unit. If the odor adjustment unit is disabled, it is considered to be enabled at level 0. If multiple fragrances are available, a setting including the fragrance selection may also be received in step S106.

[0038] In step S108, air conditioning method 10 determines the air volume of the odor control unit based on the ambient temperature detected in step S102, the operating status determined in step S104, and the settings for the odor control unit received in step S106. While step S108 considers the impact of ambient temperature, operating status, and settings on the air volume of the odor control unit, these impacts may be weighted differently. In some cases, if one or more impacts dominate, it may even be possible to ignore one or more impacts, meaning that these impacts can be disregarded when determining the air volume of the odor control unit.

[0039] In some embodiments of the present application, the process of determining the air volume in step S108 may specifically include: if the detected ambient temperature is higher than a first threshold, stopping the air volume output of the odor adjustment unit. For example, after the vehicle has been exposed to the sun, the temperature inside the vehicle is high. At this time, turning on the odor adjustment unit will cause a large amount of fragrance to dissipate. In some examples, if the temperature inside the vehicle is higher than 40°C, the odor adjustment unit will no longer be turned on, thereby reducing unnecessary consumption. See also Figure 3 The fan 343 in the fragrance system 304 is used to control the size of the output air flow, so the air output can be stopped by adjusting the fan 343 of the fragrance system 304.

[0040] In some embodiments of the present application, the air volume of the odor adjustment unit includes a basic air volume at a concentration level, and the basic air volume at each level is pre-calibrated by the following method.

[0041] In some examples, the basic air volume based on the default working state and default ambient temperature at each concentration gear can be calibrated according to the minimum air volume. For example, the default working state is that the fan of the air conditioning system 302 is turned off, and the default ambient temperature is 10°C to 30°C. The conditions for determining the basic air volume are the common working conditions of the common fragrance system 304. On the one hand, this will reduce the complexity of the calculation of the compensation air volume to be described in detail below, and on the other hand, it is also convenient to quickly determine the actual output air volume. In some examples, since the conditions for determining the basic air volume correspond to the common working conditions of the vehicle, the compensation air volume may be 0, and the actual output air volume is equal to the basic air volume. The following table shows an example of the basic air volume setting determined based on the working state of the temperature control unit (assuming that the fragrance system 304 has only two gears). Calibration can be performed by on-site calibration and theoretical calculation, which will not be repeated here. The calibration results can be stored in a table form, for example, so that they can be called in the process of determining the air volume.

[0042] Air conditioning system operating conditions Concentration range Basic air volume of the fragrance system 1 Low L1 2 Low L2 3 Low L3 4 Low L4 5 Low L5 6 Low L6 7 Low L7 8 Low L8 1 high L9 2 high L10 3 high L11 4 high L12 5 high L13 6 high L14 7 high L15 8 high L16

[0043] In some embodiments of the present application, the air volume of the odor adjustment unit also includes a compensation air volume at the concentration level received in step S106, wherein the compensation air volume is used to correct the base air volume described above. The compensation herein and in the context of the present application can be either positive compensation or negative compensation.

[0044] In some embodiments of the present application, the working state of the temperature regulating unit includes the fan air volume of the temperature regulating unit. In step S108, the compensation air volume can be determined based on the fan air volume. The following table shows the setting of the compensation air volume when only the fan air volume is considered.

[0045] Compensation air volume for the fragrance system condition f1 Fan air volume <= 40%; concentration level: low f2 40% < Fan air volume <= 60%; Concentration level: Low f3 60% < Fan air volume; Concentration level: Low f4 Fan air volume <= 40%; concentration level: high f5 40% < Fan air volume <= 60%; Concentration level: High f6 60% < Fan air volume; Concentration level: High 0 other

[0046] When for example Figure 3 When the air volume of the fan (not shown) of the air conditioning system 302 is large, the compensation air volume can be increased, thereby making it more convenient for the fragrance system 304 to release fragrance from the second air duct 341.

[0047] In some embodiments of the present application, if the ambient temperature is not higher than a first threshold (continuing the above example, for example, 40°C), the compensation air volume may be determined based on the ambient temperature in step S108. The following table illustrates the compensation air volume setting when only the ambient temperature is considered.

[0048] Compensation air volume for the fragrance system condition d1 Environmental dimension <=10℃; Concentration level: low d2 10°C < Environmental dimension <= 30°C; Concentration level: Low d3 30°C < environmental dimension <= 40°C; Concentration level: low d4 Environmental dimension <=10℃; Concentration level: High d5 10°C < Environmental dimension <= 30°C; Concentration level: High d6 30°C < environmental dimension <= 40°C; concentration level: high 0 other

[0049] In some examples, if the scent control unit is set to its default setting (e.g., the default setting), the air volume of the scent control unit can be determined solely based on the concentration setting, ambient temperature, and the operating status of the temperature control unit. For example, if the concentration setting is low, the operating status of the temperature control unit is "Operating Condition 7," and the current ambient temperature is between 10°C and 30°C, the air volume of the scent control unit can be determined as: L7 + d2. In some examples, when the ambient temperature is too low or too high, the compensatory air volume can be set slightly higher to ensure that more fragrance molecules remain in the vehicle interior.

[0050] In some embodiments of the present application, in step S108, the compensation air volume may be determined based on the external circulation ratio of the temperature adjustment unit. The following table shows the setting of the compensation air volume when only the external circulation ratio is considered.

[0051] Compensation air volume for the fragrance system condition c1 Internal circulation 100%; external circulation ratio 100%; concentration gear: low c2 Internal circulation 100%; 40% <= external circulation ratio < 100%; concentration gear: low c3 Internal circulation 100%; 35%<= external circulation ratio<40; concentration gear: low c4 Internal circulation 100%; 25%<= external circulation ratio<35%; concentration gear: low c5 Internal circulation 100%; 15%<=external circulation ratio<25%; concentration gear: low c6 Internal circulation 100%; external circulation ratio <15%; concentration gear: low c7 Internal circulation 100%; external circulation ratio 100%; concentration gear: high c8 Internal circulation 100%; 40%<=external circulation ratio<100%; concentration gear: high c9 Internal circulation 100%; 35%<= external circulation ratio<40; concentration gear: high c10 Internal circulation 100%; 25%<= external circulation ratio<35%; concentration gear: high c11 Internal circulation 100%; 15%<=external circulation ratio<25%; concentration gear: high c12 Internal circulation 100%; external circulation ratio <15%; concentration range: high 0 other

[0052] When the external circulation ratio of the temperature control unit increases, the outside air blown in will have a dilution effect on the internal fragrance. Therefore, when the external circulation ratio is too large, the compensating air volume can be appropriately increased to allow the fragrance to evaporate more and faster.

[0053] It should be noted that the above examples show setting the odor control unit's compensation air volume based solely on the temperature control unit's fan volume, ambient temperature, and the temperature control unit's external circulation ratio. However, these factors can also be combined (for example, based on at least one of them) to set the odor control unit's compensation air volume. For example, if both the ambient temperature and the temperature control unit's operating status are considered simultaneously, the configuration shown in the following table can be achieved.

[0054] Compensation air volume for the fragrance system condition z1 Environmental dimension <=10℃; internal circulation 100%; external circulation ratio 100%; concentration level: low z2 10°C < Environmental dimension <= 30°C; Inner circulation 100%; 40% <= Outer circulation ratio < 100%; Concentration level: Low z3 30°C < environmental dimension <= 40°C; 100% internal circulation; 35% <= external circulation ratio < 40; concentration level: low …… …… 0 other

[0055] According to the above configuration scheme, for example, if the working status of the temperature control unit is "working condition 7", the current ambient temperature is between 10℃ and 30℃, the internal circulation is 100%, 40%<=external circulation ratio<100% and the concentration position is low, then the air volume of the odor adjustment unit can be determined to be L7+z2.

[0056] In some embodiments of the present application, if the sum of the compensating air volume and the base air volume exceeds the minimum air volume, the sum of the compensating air volume and the base air volume is used as the air volume of the odor adjustment unit; otherwise, the minimum air volume is used as the air volume of the odor adjustment unit. This can avoid the backflow situation described above when the air volume is less than the minimum air volume. In other examples, the air volume output of the odor adjustment unit can also be stopped if the sum of the compensating air volume and the base air volume is less than the minimum air volume.

[0057] According to another aspect of the present application, a vehicle air conditioning system is provided. Figure 2 As shown, the vehicle air conditioning system includes a temperature control unit 202 and an odor control unit 204, which share an air duct. The temperature control unit 202 is configured to detect and adjust the ambient temperature within the vehicle. The odor control unit 204 is configured to receive a setting for its concentration level and determine the air volume of the odor control unit based on the ambient temperature, the operating state of the temperature control unit 202, the minimum air volume of the odor control unit in the operating state, and the concentration level of the odor control unit 204.

[0058] In some examples, according to the kinetic theory of molecules, the movement and diffusion of fragrance molecules are related to temperature. Therefore, the number of fragrance molecules perceived by the human olfactory system (the intensity of the odor) is also related to the ambient temperature. Therefore, the ambient temperature can be detected first, and then the method of fragrance release can be determined based at least in part on the detected temperature.

[0059] In some examples, because the temperature adjustment unit 202 shares an air duct with the scent adjustment unit 204 (e.g., a fragrance system) described below, the operating state of the temperature adjustment unit 202 (e.g., whether it is on, the operating position, the fan speed, etc.) will affect the operation of the scent adjustment unit 204. In some examples of the present invention, the method of releasing fragrance can be determined at least in part based on the operating state of the temperature adjustment unit 202.

[0060] As described above, the air flow from the air conditioning system 302 passes through the first air duct 321, and the air flow from the fragrance system 304 flows through the fragrance cartridge 342 and the second air duct 341, and then the two air flows merge into the air duct 306. It is worth noting that when the air conditioning system 302 is operating, the pressure generated at the outlet of the first air duct 321 may be greater than the pressure at the outlet of the second air duct 341. Therefore, the air flow from the second air duct 341 will be significantly affected by the air flow from the first air duct 321. In other words, the air conditioning system 302 will affect the operation of the fragrance system 304 to a certain extent. Therefore, in some examples of the present invention, the operating status of the temperature adjustment unit 202 can be determined first, and then the operating mode of the fragrance system can be configured at least in part based on its operating status.

[0061] In some examples, the minimum air volume of the odor adjustment unit can be determined based on the operating status of the temperature adjustment unit. Figure 6As shown, air conditioning system 302 and fragrance system 304 are simultaneously activated. Specifically, damper 322 of air conditioning system 302 remains open, and fan 343 of fragrance system 304 is also on. To ensure that the fragrance in fragrance system 304 can be rapidly and controlled diffused across all air conditioning system 302 and air outlet settings, and to prevent adverse effects such as unintended backflow, fan 343 must maintain a minimum airflow output.

[0062] The following table illustrates the minimum speed requirements for fan 343 of fragrance system 304 to ensure fragrance can be dispensed under different operating conditions of air conditioning system 302 for a specific vehicle model. The speed of fan 343 of fragrance system 304 must be adjusted to ensure that the outlet of second air duct 341 of fragrance system 304 can overcome the corresponding back pressure.

[0063] Air conditioning system operating conditions Air volume of air conditioning system under different working conditions (CMH) The back pressure that the fragrance system fan must overcome at its minimum speed (Pa) 1 89.46 10.02 2 122.29 18.73 3 153.48 29.50 4 188.77 44.63 5 229.81 66.15 6 283.16 100.42 7 350.22 153.62 8 435.00 237.00

[0064] To this end, the speed of the fan 343 of the fragrance system 304 can be matched to the operating state of the air conditioning system 302 (e.g., its fan gear position) to ensure that backflow does not occur, preventing the fragrance from being blown out. The flow rate generated by the speed required to overcome back pressure and ensure the fragrance is blown out is called the minimum air volume, which is related to the operating state of the temperature control unit 202 (e.g., the operating conditions in the table above). The following table shows an example of the minimum air volume setting determined based on the operating state of the temperature control unit 202.

[0066] Figure 3-Figure 6 The air conditioning system 302 and the fragrance system 304 are shown sharing a common air duct 306. Figure 3 In the example, the air conditioning system 302 and the fragrance system 304 are both in the off state, specifically, the damper 322 (and its fan, not shown in the figure) of the air conditioning system 302 is closed, and the fan 343 of the fragrance system 304 stops working. Figure 4 In the example, only the air conditioning system 302 is turned on, and the damper 322 (and its fan, not shown in the figure) remains open. The fan 343 of the fragrance system 304 stops working. Figure 5 In the example, only the fragrance system 304 is turned on, and the fan 343 remains on. The damper 322 of the air conditioning system 302 (and its fan, not shown in the figure) is closed. Figure 6 In the example, the air conditioning system 302 and the fragrance system 304 are both in the on state. At this time, the damper 322 (and its fan, not shown in the figure) of the air conditioning system 302 remains in the open state, and the fan 343 of the fragrance system 304 remains in the on state.

[0067] In some examples, the setting of the concentration level of the scent adjustment unit 204 may include a setting of whether to enable or disable the scent adjustment unit. If the scent adjustment unit is disabled, it may be considered to be enabled at level 0. If applicable, if multiple fragrances are available, the scent adjustment unit 204 may also receive a setting including a fragrance selection.

[0068] In some examples, the odor adjustment unit 204 determines its air volume based on the ambient temperature, the operating status of the temperature adjustment unit 202, and the settings of the odor adjustment unit 204. While the effects of the ambient temperature, operating status, and settings on the air volume of the odor adjustment unit 204 are all considered, these influences may be weighted differently. In some examples, if one or more influences dominate, it may even be possible to ignore one or more of them. In other words, these influences can be disregarded when determining the air volume of the odor adjustment unit 204.

[0069] In some embodiments of the present application, the odor adjustment unit 204 is configured to stop the air volume output of the odor adjustment unit 204 when the ambient temperature is higher than a first threshold. For example, after the vehicle has been exposed to the sun, the temperature inside the vehicle is high. At this time, turning on the odor adjustment unit 204 will cause a large amount of fragrance to be dissipated. In some examples, if the temperature inside the vehicle is higher than 40°C, the odor adjustment unit will not be turned on, thereby reducing unnecessary consumption. See also Figure 3 The fan 343 in the fragrance system 304 is used to control the size of the output air flow, so the air output can be stopped by adjusting the fan 343 of the fragrance system 304.

[0070] In some embodiments of the present application, the odor adjustment unit 204 is configured to determine the basic air volume under the received concentration level, and the basic air volume under each level can be pre-calibrated by the following method.

[0071] In some examples, the basic air volume based on the default working state and default ambient temperature at each concentration gear can be calibrated according to the minimum air volume. For example, the default working state is that the fan of the air conditioning system 302 is turned off, and the default ambient temperature is 10°C to 30°C. The conditions for determining the basic air volume are the common working conditions of the common fragrance system 304. On the one hand, this will reduce the complexity of the calculation of the compensation air volume to be described in detail below, and on the other hand, it is also convenient to quickly determine the actual output air volume. In some examples, since the conditions for determining the basic air volume correspond to the common working conditions of the vehicle, the compensation air volume may be 0, and the actual output air volume is equal to the basic air volume. The following table shows an example of the basic air volume setting determined based on the working state of the temperature control unit (assuming that the fragrance system 304 has only two gears). Calibration can be performed by on-site calibration and theoretical calculation, which will not be repeated here. The calibration results can be stored in a table form, for example, so that they can be called in the process of determining the air volume.

[0072] Air conditioning system operating conditions Concentration range Basic air volume of the fragrance system 1 Low L1 2 Low L2 3 Low L3 4 Low L4 5 Low L5 6 Low L6 7 Low L7 8 Low L8 1 high L9 2 high L10 3 high L11 4 high L12 5 high L13 6 high L14 7 high L15 8 high L16

[0073] In some embodiments of the present application, the air volume of the odor adjustment unit is further configured to determine a compensation air volume under the received concentration gear setting, wherein the compensation air volume is used to correct the basic air volume described above. Compensation here and in the context of this application can be positive compensation or negative compensation.

[0074] In some embodiments of the present application, the operating state includes the fan air volume of the temperature adjustment unit 202, and the odor adjustment unit 204 is configured to determine the compensation air volume based on the fan air volume of the temperature adjustment unit 202. The following table shows the setting of the compensation air volume when only the fan air volume is considered.

[0075] Compensation air volume for the fragrance system condition f1 Fan air volume <= 40%; concentration level: low f2 40% < Fan air volume <= 60%; Concentration level: Low f3 60% < Fan air volume; Concentration level: Low f4 Fan air volume <= 40%; concentration level: high f5 40% < Fan air volume <= 60%; Concentration level: High f6 60% < Fan air volume; Concentration level: High 0 other

[0076] When for example Figure 3 When the air volume of the fan (not shown) of the air conditioning system 302 is large, the compensation air volume can be increased, thereby making it more convenient for the fragrance system 304 to release fragrance from the second air duct 341.

[0077] In some embodiments of the present application, the odor adjustment unit 204 is configured to determine the compensating air volume based on the ambient temperature when the ambient temperature is not higher than a first threshold (continuing the above example, e.g., 40°C). The following table illustrates the compensating air volume settings when only the ambient temperature is considered.

[0078] Compensation air volume for the fragrance system condition d1 Environmental dimension <=10℃; Concentration level: low d2 10°C < environmental dimension <= 30°C; Concentration level: low d3 30°C < environmental dimension <= 40°C; Concentration level: low d4 Environmental dimension <=10℃; Concentration level: High d5 10°C < environmental dimension <= 30°C; Concentration level: high d6 30°C < environmental dimension <= 40°C; Concentration level: high 0 other

[0079] In some examples, if the scent adjustment unit 204 is set to a default value (e.g., the default setting), the air volume of the scent adjustment unit 204 can be determined solely based on the concentration setting, ambient temperature, and the operating state of the temperature adjustment unit 202. For example, if the concentration setting is low, the operating state of the temperature adjustment unit 202 is "Operating Condition 7," and the current ambient temperature is between 10°C and 30°C, the air volume of the scent adjustment unit 204 can be determined as: L7 + d2. In some examples, when the ambient temperature is too low or too high, the compensatory air volume can be set slightly higher to ensure that more fragrance molecules remain in the vehicle interior.

[0080] In some embodiments of the present application, the odor adjustment unit 204 is configured to determine the compensation air volume based on the external circulation ratio of the temperature adjustment unit 202. The following table shows the setting of the compensation air volume when only the external circulation ratio is considered.

[0081] Compensation air volume for the fragrance system condition c1 Internal circulation 100%; external circulation ratio 100%; concentration gear: low c2 Internal circulation 100%; 40% <= external circulation ratio < 100%; concentration gear: low c3 Internal circulation 100%; 35%<= external circulation ratio<40; concentration gear: low c4 Internal circulation 100%; 25%<= external circulation ratio<35%; concentration gear: low c5 Internal circulation 100%; 15%<=external circulation ratio<25%; concentration gear: low c6 Internal circulation 100%; external circulation ratio <15%; concentration gear: low c7 Internal circulation 100%; external circulation ratio 100%; concentration gear: high c8 Internal circulation 100%; 40%<=external circulation ratio<100%; concentration gear: high c9 Internal circulation 100%; 35%<= external circulation ratio<40; concentration gear: high c10 Internal circulation 100%; 25%<= external circulation ratio<35%; concentration gear: high c11 Internal circulation 100%; 15%<=external circulation ratio<25%; concentration gear: high c12 Internal circulation 100%; external circulation ratio <15%; concentration range: high 0 other

[0082] When the external circulation ratio of the temperature adjustment unit 202 increases, the blown-in external air will have a dilution effect on the internal fragrance. Therefore, when the external circulation ratio is too large, the compensating air volume can be appropriately increased to allow the fragrance to evaporate more quickly.

[0083] It should be noted that the above example shows setting the compensating air volume of the odor control unit 204 based solely on the fan air volume of the temperature control unit 202, the ambient temperature, and the external circulation ratio of the temperature control unit 202. However, these factors can also be combined (for example, based on at least one of them) to set the compensating air volume of the odor control unit 204. For example, if the ambient temperature and the operating status of the temperature control unit 202 are also considered, the configuration scheme shown in the following table can be formed.

[0084] Compensation air volume for the fragrance system condition z1 Environmental dimension <=10℃; internal circulation 100%; external circulation ratio 100%; concentration level: low z2 10°C < Environmental dimension <= 30°C; 100% internal circulation; 40% <= External circulation ratio < 100%; Concentration level: Low z3 30°C < Environmental dimension <= 40°C; Inner circulation 100%; 35% <= Outer circulation ratio < 40; Concentration level: Low …… …… 0 other

[0085] According to the above configuration scheme, for example, if the working state of the temperature adjustment unit 202 is "working condition 7", the current ambient temperature is between 10°C and 30°C, the internal circulation is 100%, 40%<=external circulation ratio<100% and the concentration position is low, then the air volume of the odor adjustment unit 204 can be determined to be L7+z2.

[0086] In some embodiments of the present application, the odor adjustment unit is configured to: if the sum of the compensating air volume and the base air volume is greater than the minimum air volume, the sum of the compensating air volume and the base air volume is used as the air volume of the odor adjustment unit; otherwise, the minimum air volume is used as the air volume of the odor adjustment unit. In this way, the backflow situation described above can be avoided when the air volume is less than the minimum air volume. In other examples, the odor adjustment unit can also be configured to stop the air volume output of the odor adjustment unit when the sum of the compensating air volume and the base air volume is less than the minimum air volume.

[0087] According to another aspect of the present application, a vehicle is provided, which includes any one of the vehicle air conditioning systems described above, thereby enabling the vehicle equipped with the air conditioning system to precisely adjust the degree of fragrance release.

When the instructions are executed by a processor, the processor is caused to perform any of the air conditioning methods described above. The computer-readable medium referred to in the present application includes various types of computer storage media, and can be any available medium that can be accessed by a general-purpose or special-purpose computer. For example, the computer-readable medium can include RAM, ROM, EPROM, E 2PROM, register, hard disk, removable disk, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage device, or any other temporary or non-temporary medium that can be used to carry or store desired program code units in the form of instructions or data structures and can be accessed by a general or special purpose computer, or a general or special purpose processor.
