[0003] In the related art, usually according to a set target temperature, the temperature and air flow speed inside the vehicle are adjusted, while ignoring the adjustment of the humidity inside the vehicle. That is, there is a lack of an effective method for adjusting the humidity inside the vehicle in the related art. Summary of the Invention

[0004] In view of the above problems, embodiments of the present invention provide a humidity control method, a vehicle, a device, an electronic device, and a readable storage medium that overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] In a first aspect, an embodiment of the present application discloses a humidity control method, including:

[0007] Obtaining a first humidity inside a vehicle;

[0008] If the first humidity is within a first preset humidity range, then according to the first temperature, the first humidity inside the vehicle, the second temperature and the second humidity outside the vehicle, determining an opening degree of a circulation air door of an air conditioner in the vehicle, and adjusting the first humidity to a target humidity according to the opening degree of the circulation air door;

[0009] If the first humidity is within a second preset humidity range, then according to the first temperature and the target humidity, determining a rotation speed of a compressor of the air conditioner, and adjusting the first humidity to the target humidity according to the rotation speed of the compressor; wherein, an upper limit value of the first preset humidity range is less than or equal to a lower limit value of the second preset humidity range.

[0010] In a second aspect, an embodiment of the present application discloses a humidity control device, including:

[0011] A first obtaining module, configured to obtain a first humidity inside a vehicle;

[0012] The first control module is configured to, if the first humidity is within the first preset humidity range, determine the opening degree of the circulation air damper of the air conditioner in the vehicle according to the first temperature inside the vehicle, the first humidity, the second temperature and the second humidity outside the vehicle, and adjust the first humidity to the target humidity according to the opening degree of the circulation air damper;

[0013] The second control module is configured to, if the first humidity is within the second preset humidity range, determine the rotational speed of the compressor of the air conditioner according to the first temperature and the target humidity, and adjust the first humidity to the target humidity according to the rotational speed of the compressor; wherein, the upper limit value of the first preset humidity range is less than or equal to the lower limit value of the second preset humidity range.

[0014] In a third aspect, an embodiment of the present application discloses an electronic device, including a processor and a memory, where the memory stores a program or instruction that can run on the processor, and when the program or instruction is executed by the processor, the steps of the method described in the first aspect are implemented.

When the first humidity is within the first preset humidity range, the opening degree of the circulation air door of the air conditioner in the vehicle is quantitatively calculated based on the first temperature inside the vehicle, the second temperature outside the vehicle, and the second humidity. Then, the operation of the circulation air door of the vehicle air conditioner is controlled according to the quantitatively calculated opening degree of the circulation air door. When the first humidity is within the second preset humidity range, the compressor speed of the compressor in the air conditioner is quantitatively calculated based on the first temperature and the target humidity, so as to accurately control the operation of the compressor according to the quantitatively calculated compressor speed. In addition, the upper limit value of the first preset humidity range is less than or equal to the lower limit value of the second preset humidity range. Therefore, the humidity in the first preset humidity range is lower than that in the second preset humidity range. In the case of relatively low humidity, the humidity can be adjusted to the target humidity by adjusting the opening degree of the circulation air door. However, when the humidity is relatively high, only adjusting the opening degree of the circulation air door can no longer meet the humidity adjustment requirements. Therefore, in this embodiment, when the first humidity is within the second preset humidity range, the humidity is adjusted by the accurately calculated compressor speed. Thus, it can be ensured that the humidity can be adjusted to the target humidity. In other words, through this embodiment, according to the judgment result of the first humidity being in different preset humidity ranges, different adjustment strategies are used for humidity adjustment, further improving the accuracy of humidity adjustment. Based on this embodiment, the humidity inside the vehicle can be accurately adjusted, and then a humidity adjustment result that meets the comfort requirements of users can be obtained.

[0025] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0026] Reference Figure 1 , which shows the humidity control method provided by the embodiments of the present application. The method includes:

[0027] Step 101, obtain the first humidity inside the vehicle.

[0028] The first humidity inside the vehicle can be obtained through a humidity sensor.

[0029] Among them, the vehicle can be a vehicle, an aircraft, or other vehicles with humidity adjustment requirements; the first humidity inside the vehicle can be the humidity in the cockpit and / or the cargo hold that needs to be moderately adjusted; the first humidity can be the relative humidity.

[0030] Step 102, if the first humidity is within the first preset humidity range, then determine the opening degree of the circulation air damper of the air conditioner in the vehicle according to the first temperature inside the vehicle, the first humidity, the second temperature outside the vehicle, and the second humidity, and adjust the first humidity to the target humidity according to the opening degree of the circulation air damper.

[0031] Specifically, if the first humidity is within the first preset humidity range, obtain the first temperature inside the vehicle, the second temperature outside the vehicle, and the second humidity, calculate the opening degree of the circulation air damper of the air conditioner in the vehicle according to the first temperature, the second temperature, the first humidity, and the second humidity, and control the operation of the circulation air damper of the air conditioner according to the opening degree of the circulation air damper to adjust the first humidity to the target humidity.

[0032] The second temperature outside the vehicle is the ambient temperature outside the vehicle, and the second humidity outside the vehicle is the relative ambient humidity outside the vehicle. The target humidity can be the humidity set by the user or the humidity automatically set by the vehicle that can meet the user's comfort requirements or the humidity requirements inside the vehicle.

[0033] The humidity in the first preset humidity range is higher than the preset humidity that makes the user feel comfortable or meets the storage requirements of the cargo in the cargo hold. For example, the first humidity RH in is within the first preset humidity range. Exemplarily, the first preset humidity range can be [RH0, RH1); where RH0 is the preset humidity that makes the user feel comfortable. For example, RH0 can be 55%. RH1 is the first humidity critical value calculated according to the preset humidity.

[0034] Exemplarily, obtain the conversion relationship between the internal temperature of the vehicle, the internal humidity of the vehicle, the external temperature of the vehicle, the external humidity of the vehicle, and the opening degree of the circulation air door. According to the conversion relationship, and the first temperature, the second temperature, the first humidity, and the second humidity, calculate the opening degree of the circulation air door of the air conditioner in the vehicle.

[0035] Specifically, adjust the opening degree of the circulation air door of the air conditioner to the opening degree of the circulation air door obtained in this step. By adjusting the opening degree of the circulation air door of the circulation air door, adjust the first humidity to the target humidity.

[0036] Further, if the first humidity is within the first preset humidity range, obtain the rotational speed of the air conditioner compressor and the working mode of the mode air door according to the temperature after the outlet of the air conditioner evaporator (TAO); obtain the blower air volume corresponding to the first humidity according to the corresponding relationship between the preset blower air volume and the preset humidity. Then control the operation of the circulation air door according to the opening degree of the circulation air door determined in this embodiment, control the operation of the compressor according to the obtained rotational speed of the compressor, control the operation of the mode air door according to the working mode of the mode air door, control the operation of the blower according to the blower air volume, and adjust the first humidity to the target humidity based on the coordinated processing of the circulation air door, the compressor, the mode air door, and the blower.

[0037] Step 103, if the first humidity is within the second preset humidity range, determine the rotational speed of the air conditioner compressor according to the first temperature and the target humidity, and adjust the first humidity to the target humidity according to the rotational speed of the compressor.

[0038] Specifically, if the first humidity is within the second preset humidity range, calculate the rotational speed of the air conditioner compressor according to the first temperature and the target humidity, and control the operation of the air conditioner compressor according to the rotational speed of the compressor to adjust the first humidity to the target humidity.

[0039] Among them, the upper limit value of the first preset humidity range is less than or equal to the lower limit value of the second preset humidity range. Correspondingly, the humidity in the first preset humidity range is less than the humidity in the second preset humidity range.

[0040] Further, the second preset humidity range may include a first sub-preset humidity range and a second sub-preset humidity range, and the upper limit value of the humidity in the first sub-preset humidity range is less than or equal to the lower limit value of the second sub-preset humidity range.

[0041] If the first humidity is within the first sub - preset humidity range, obtain the working mode of the mode air door according to the TAO value, and obtain the blower air volume corresponding to the first humidity according to the corresponding relationship between the preset blower air volume and the preset humidity; adjust the working mode of the circulation air door to the internal circulation mode. Then control the operation of the compressor according to the compressor speed determined in this embodiment; control the operation of the circulation air door through the internal circulation mode, control the operation of the mode air door through the working mode of the mode air door, control the operation of the blower through the blower air volume, and based on the coordinated processing of the circulation air door, compressor, mode air door and blower, adjust the first humidity to the target humidity.

[0042] If the first humidity is within the second sub - preset humidity range, set the working mode of the circulation air door to the internal circulation mode, set the working mode of the mode air door to the window - blowing mode, and obtain the blower air volume corresponding to the first humidity according to the corresponding relationship between the preset blower air volume and the preset humidity. Then, based on the coordinated processing of the circulation air door, compressor, mode air door and blower, adjust the first humidity to the target humidity.

[0043] The target temperature corresponding to the target humidity can be obtained according to the corresponding relationship between the preset temperature and the preset humidity; the target temperature is the outlet temperature of the compressor. The compressor speed of the compressor can be obtained according to the conversion relationship between the preset temperature inside the vehicle, the preset outlet temperature of the compressor, and the preset speed of the compressor, as well as the first temperature and the target temperature of the vehicle.

[0044] Further, if the first humidity is within the third preset humidity range, obtain the opening degree of the circulation air door, the operation mode of the mode air door, the compressor speed and the blower speed according to the TAO value, and then, based on the coordinated processing of the circulation air door, compressor, mode air door and blower, adjust the first humidity to the target humidity. Among them, the upper limit value of the third preset humidity range is less than or equal to the lower limit value of the first preset humidity range.

[0045] For vehicles, airplanes and other driving tools with driving functions, if the humidity inside (such as the passenger compartment) is too high or too low, it may make the passengers feel uncomfortable. For example, if the humidity is too high, it may cause discomfort such as chest tightness, shortness of breath and difficulty in breathing for the passengers; a higher humidity will also affect the driving safety of the vehicle. For example, excessive humidity may cause the front windshield to fog up and affect the driver's vision; for example, if the humidity is too low, it may cause problems such as dry skin for the passengers. Reasonable humidity control can improve the comfort and driving safety inside the vehicle.

[0046] The air conditioner automatic control algorithm of the related technology can only reasonably adjust the temperature and air flow speed in the passenger compartment, but lacks reasonable control over the humidity in the passenger compartment. In the related technology, by obtaining the sensor measurement values and the control information input through human-machine interaction, the air volume and air outlet temperature of the air conditioner are controlled. For example, temperature control can be performed through the heat load to characterize the temperature difference (TemperatureDifference, TD), TAO value, and by obtaining the proportional-integral-derivative control (Proportional-Integral-Derivative Control, PID) temperature feedback control algorithm, etc., to control the temperature in the cockpit. However, these automatic air conditioner algorithms can only adjust the temperature and air flow speed in the passenger compartment, and cannot accurately control the humidity in the passenger compartment.

[0047] In this embodiment, the first humidity inside the vehicle is obtained. When the first humidity is within the first preset humidity range, the opening degree of the circulation air door of the air conditioner in the vehicle is quantitatively calculated according to the first temperature inside the vehicle, the second temperature outside the vehicle, and the second humidity, and then the operation of the circulation air door of the vehicle air conditioner is controlled according to the quantitatively calculated opening degree of the circulation air door. When the first humidity is within the second preset humidity range, the compressor speed of the compressor in the air conditioner is quantitatively calculated according to the first temperature and the target humidity, so as to accurately control the operation of the compressor according to the quantitatively calculated compressor speed. The opening degree of the circulation air door or the compressor speed quantitatively calculated based on the relevant parameters in this embodiment can accurately adjust the humidity. Compared with the method of obtaining the reference values of temperature or air volume according to empirical data and adjusting the temperature and air volume based on the reference values to realize humidity adjustment, this embodiment can avoid the problem of low accuracy of the adjustment result when adjusting the humidity according to the reference air volume and reference temperature set according to empirical values.

[0048] In addition, the upper limit value of the first preset humidity range is less than or equal to the lower limit value of the second preset humidity range. Therefore, the humidity in the first preset humidity range is lower than the humidity in the second preset humidity range. In the case of low humidity, the humidity can be adjusted to the target humidity by adjusting the opening degree of the circulation air door. However, in the case of high humidity, only adjusting the opening degree of the circulation air door can no longer meet the humidity adjustment requirements. Therefore, in this embodiment, when the first humidity is within the second preset humidity range, the humidity is adjusted by the accurately calculated compressor speed. Thus, it can be ensured that the humidity can be adjusted to the target humidity. In other words, through this embodiment, according to the judgment result of the first humidity in different preset humidity ranges, different adjustment strategies are used to adjust the humidity, further improving the accuracy of humidity adjustment. Based on this embodiment, the humidity inside the vehicle can be accurately adjusted, and then a humidity adjustment result that meets the comfort requirements of users can be obtained.

[0049] Reference Figure 2, which shows the humidity control method provided by the embodiments of the present application. The method includes:

[0050] Step 201, obtain the first humidity inside the vehicle.

[0051] The method of this step has been described in the previous step 101 and will not be elaborated here.

[0052] Step 202, if the first humidity is within the first preset humidity range, obtain the first saturation vapor pressure corresponding to the first temperature and the second saturation vapor pressure corresponding to the second temperature.

[0053] Exemplarily, according to the corresponding relationship between the preset humidity and the preset saturation vapor pressure, obtain the first saturation vapor pressure corresponding to the first temperature and the second saturation vapor pressure corresponding to the second temperature.

[0054] Step 203, determine the opening degree of the circulation air door of the air conditioner according to the first saturation vapor pressure, the second saturation vapor pressure, the first humidity and the second humidity, and adjust the first humidity to the target humidity according to the opening degree of the circulation air door.

[0055] There is a direct relationship between the saturation vapor pressure and the humidity, and the two affect each other through the phase change process of water. The saturation vapor pressure can more intuitively characterize the humidity. Obtain the first saturation vapor pressure corresponding to the first temperature and the second saturation vapor pressure corresponding to the second temperature, and then obtain the opening degree of the circulation air door of the air conditioner through the first saturation vapor pressure, the second saturation vapor pressure, the first humidity and the second humidity. The calculation result of the opening degree of the circulation air door obtained in this way is more accurate.

[0056] Among them, step 203 may include sub-steps A1 to A5:

[0057] Sub-step A1, obtain the first product of the first saturation vapor pressure and the first humidity, and the second product of the second saturation vapor pressure and the second humidity.

[0058] Sub-step A2, obtain the first difference between the first product and the second product.

[0059] Sub-step A3, obtain the vapor pressure difference threshold between the internal vapor pressure and the external vapor pressure of the vehicle, and the first summation result of the vapor pressure difference threshold and the first difference.

[0060] Exemplarily, respectively obtain the absolute value ΔP of the vapor pressure difference between the internal vapor pressure and the external vapor pressure of the vehicle under different working conditions, and then compare the absolute values ΔP of the vapor pressure differences under each working condition, and determine the maximum value max(ΔP) among them as the vapor pressure difference threshold between the internal vapor pressure and the external vapor pressure of the vehicle.

[0061] Sub-step A4: Obtain the first ratio of the first summation result to the saturation steam pressure difference threshold.

[0062] Sub-step A5: Calculate the opening degree of the circulation air door of the air conditioner in the vehicle according to the first ratio.

[0063] For example, determine the opening degree of the circulation air door of the air conditioner as the product of the first ratio and a preset coefficient.

[0064] Exemplarily, the opening degree of the circulation air door of the air conditioner can be obtained according to the following method

[0065]

[0066] where P in is the first saturation steam pressure corresponding to the first humidity, RH in is the first humidity inside the vehicle, and the first humidity can be the relative humidity in the passenger compartment; P amb is the second saturation steam pressure corresponding to the second temperature (i.e., the ambient temperature) T amb outside the vehicle, RH amb is the second humidity outside the vehicle, and the second humidity can be the ambient relative humidity, which can be obtained from the weather forecast. Second, max(ΔP) is the maximum value of the steam pressure difference between the internal steam pressure and the external steam pressure of the vehicle.

[0067] When the opening degree of the circulation air door is 0, the operation mode of the circulation air door is the internal circulation. When the opening degree of the circulation air door is 100%, the operation mode of the circulation air door is the external circulation.

[0068] Based on this embodiment, when the first saturation steam pressure inside the vehicle is higher than the second saturation steam pressure outside the vehicle, and the first difference between the first product of the first saturation steam pressure and the first humidity and the second product of the second saturation steam pressure and the second humidity is greater than zero, the calculated opening degree of the circulation air door is greater than zero, and the opening degree of the circulation air door increases towards the external circulation; when the first saturation steam pressure inside the vehicle is lower than the second saturation steam pressure outside the vehicle, the first difference between the first product of the first saturation steam pressure and the first humidity and the second product of the second saturation steam pressure and the second humidity is less than zero, and the opening degree of the circulation air door increases towards the internal circulation. Through this control method, it can be ensured that the first saturation steam pressure inside the vehicle is neither too high nor too low, thereby maintaining a suitable humidity inside the vehicle and achieving the purpose of precisely adjusting the humidity inside the vehicle.

[0069] Step 204: If the first humidity is within the second preset humidity range, obtain the target temperature corresponding to the target humidity according to the corresponding relationship between the preset humidity and the preset temperature;

[0070] Step 205 , obtaining the specific heat capacity of air, the air mass flow rate of the compressor, the working volume of the compressor, the density of the refrigerant inside the compressor, the charging efficiency of the compressor, and the latent heat of vaporization of the refrigerant in the compressor;

[0071] Step 206, determining the compressor speed of the air conditioner based on the specific heat capacity of the air, the air mass flow rate of the compressor, the first temperature, the target temperature, the working volume of the compressor, the refrigerant density inside the compressor, the charging efficiency of the compressor, and the latent heat of vaporization of the refrigerant in the compressor, and adjusting the first humidity to the target humidity based on the compressor speed.

[0072] The upper limit of the first preset humidity range is less than or equal to the lower limit of the second preset humidity range.

[0073] In this embodiment, the first humidity is within the second preset humidity range, and the lower limit of the first preset humidity range is greater than or equal to the upper limit of the first preset humidity range. Therefore, the humidity within the second preset humidity range is relatively high. When the first humidity is within the second preset humidity range, it indicates that the first humidity inside the vehicle is relatively high. At this time, adjusting the opening of the circulation damper is no longer sufficient to meet the humidity regulation requirements, and the compressor needs to be started to initiate the refrigeration cycle and achieve the purpose of lowering the humidity. This embodiment calculates the compressor speed based on engine performance parameters such as the compressor's operating volume and humidity parameters such as the target humidity. This takes into account both the engine's own performance and the humidity regulation requirements. Thus, it is possible to achieve the goals of lowering the humidity inside the vehicle while meeting the compressor's operating requirements and reducing system energy consumption. That is, by calculating the compressor speed based on this embodiment and controlling the compressor operation based on this compressor speed, it is possible to both accurately and effectively regulate the humidity and save system energy consumption.

[0074] The upper limit of the first preset humidity range is less than or equal to the lower limit of the second preset humidity range.

[0075] For example, step 206 may include sub-steps B1 to B5:

[0076] Sub-step B1, obtaining a second difference between the first temperature and the target temperature.

[0077] Sub-step B2: obtaining a third product of the second difference and the air mass flow rate and air specific heat capacity of the compressor.

[0078] Sub-step B3, obtaining a fourth product of the working volume of the compressor, the density of the refrigerant inside the compressor, the charging efficiency of the compressor, and the latent heat of vaporization of the refrigerant in the compressor.

[0079] Sub-step B4: obtaining a second ratio between the third product and the fourth product.

[0080] Sub-step B5: obtaining the compressor speed of the air conditioner compressor according to the second ratio.

[0081] The product of the second ratio and the preset coefficient can be determined as the compressor speed of the air conditioner compressor; the second ratio can also be directly determined as the compressor speed; for example, the compressor speed N of the air conditioner can be obtained according to the following method: com :

[0082]

[0083] Among them, M air is the air mass flow rate of the compressor, C p is the specific heat capacity of air, T cab is the first temperature, T target is the target temperature, V d is the working volume of the compressor, ρ ref is the refrigerant density inside the compressor, η vol is the charging efficiency of the compressor, h cool It is the latent heat of vaporization of the refrigerant in the compressor.

[0084] When the humidity inside a vehicle (e.g., the passenger compartment) is relatively high, such as when the humidity level is medium to high, the humidity cannot be adjusted to the required level simply by adjusting the circulating damper. In this case, the compressor should be started and the refrigeration cycle should be turned on to adjust the humidity to the required level through the compressor.

[0085] During the compressor adjustment process, how to control the compressor speed to ensure that the humidity in the passenger compartment can be effectively reduced while reducing the system energy consumption is a problem that needs to be solved. The above processing method of this embodiment obtains the compressor speed on the basis of satisfying the energy balance, which can effectively reduce the humidity in the passenger compartment while reducing the system energy consumption. Figure 3 , the method of obtaining the compressor speed in this embodiment is further illustrated. Figure 3 Where M is the air mass flow rate, RHin and RHout are the first and second humidity, respectively.

[0086] Based on the energy balance of the compressor, the heat Q absorbed by the evaporator from the air side can be calculated according to formula (3): air :

[0087] Q air =M air C p (T cab -T target ) (3)

[0088] Among them, M air is the air mass flow rate, Cp is the specific heat capacity of air, and T cab is the inlet air temperature of the evaporator and also the first temperature inside the vehicle; T target is the target temperature of the evaporator.

[0089] Furthermore, the heat Q absorbed by the evaporator from the air side can be calculated according to formula (4) air :

[0090] Q air = A eva h ext (T ae - T eva ) (4)

[0091] where A eva is the evaporator area of the evaporator, h ext is the convective heat transfer coefficient, and T ae is the air temperature around the evaporator:

[0092] According to formula (3) and formula (4), the evaporation temperature T eva can be expressed as:

[0093]

[0094] If the superheat and subcooling of the refrigerant can be ignored, then the heat Q absorbed by the refrigerant from the evaporator cool is:

[0095] Q cool = M com h cool (6)

[0096] where h cool is the latent heat of vaporization of refrigerant evaporation, and M com is the refrigerant mass flow rate.

[0097] According to formula (6), the refrigerant mass flow rate M com is:

[0098]

[0099] Furthermore, the refrigerant mass flow rate M com is:

[0100] M com = N com V d ρ ref η vol (10)

[0101] where N com is the compressor speed, V d is the working volume of the compressor, and ρref is the density of the refrigerant inside the compressor, and η vol is the charging efficiency. According to formulas (3), (7), (8), and (10), the compressor speed N com is:

[0102]

[0103] where T cab is the inlet air temperature of the evaporator and can be obtained according to formula (9).

[0104] Exemplarily, in the case where the air in the evaporator is in a saturated state, the temperature T target corresponding to the target humidity RH of the evaporator outlet air target can also be obtained according to the psychrometric chart:

[0105] T target = f(RH target ) (12)

[0106] where the air mass flow rate M air can be expressed as:

[0107] M air = f(N fan ) (13)

[0108] According to formula (13), the air mass flow rate M air is related to the blower air volume N fan and the corresponding relationship f(N fam ) between different blower air volumes N air and the air mass flow rate M fan can be obtained by the calibration method. The corresponding relationship f(N fan ) can be in the form of a mapping table or a fitting function.

[0109] where the density ρ of the refrigerant inside the compressor ref can be expressed as:

[0110] ρ ref = f(T eva ) (14)

[0111] According to formula (14), the density ρ of the refrigerant inside the compressor ref is related to T eva and the corresponding relationship f(T ref ) between different refrigerant densities ρ inside the compressor eva and T eva can be obtained by the calibration method. The corresponding relationship f(T eva)It can be in the form of a mapping table or a fitting function. Further, T can be calculated according to formula (5). eva , substitute T eva into the expression of formula (14), and the density ρ inside the compressor can be obtained. ref .

[0112] Further, combining formulas (12) to (14), the compressor speed N com can also be expressed as:

[0113]

[0114] In this embodiment, the second difference between the first temperature and the target temperature is obtained, the third product of the second difference, the air mass flow rate of the compressor, and the specific heat capacity of the air is obtained, the fourth product of the working volume of the compressor, the refrigerant density inside the compressor, the charging efficiency of the compressor, and the latent heat of vaporization of the refrigerant evaporation of the compressor is obtained, the second ratio between the third product and the fourth product is obtained, and the compressor speed of the compressor of the air conditioner is obtained according to the second ratio. Based on this method, the compressor speed required to adjust the first humidity inside the vehicle to the target humidity can be accurately and quantitatively calculated.

[0115] Exemplarily, the second preset humidity range includes a first sub-preset humidity range and a second sub-preset humidity range; the upper limit value of the first sub-preset humidity range is less than or equal to the lower limit value of the second sub-preset humidity range; after step 201, the method further includes:

[0116] Step 207, if the first humidity is within the first sub-preset humidity range, obtain the target temperature of the air conditioner evaporator according to the target humidity, obtain the target operating mode corresponding to the target outlet temperature according to the correspondence between the preset outlet temperature and the preset operating mode of the mode damper, so as to control the operation of the mode damper according to the target operating mode.

[0117] For example, when the operating state of the mode damper is different, the air outlet direction of the air conditioner is also different. For example, it can include modes such as blowing on the window and defrosting.

[0118] The target outlet temperature corresponding to the target humidity can be obtained according to the psychrometric chart.

[0119] Step 208, if the first humidity is within the second sub-preset humidity range, set the operating mode of the mode damper to the window-blowing mode.

[0120] In this embodiment, if the first humidity is within the first sub - preset humidity range, the target outlet temperature of the air - conditioner evaporator is obtained according to the target humidity, and according to the corresponding relationship between the preset outlet temperature and the preset operation mode of the mode damper, the target operation mode corresponding to the target outlet temperature is obtained, so as to control the operation of the mode damper according to the target operation mode. Thus, the operation mode of the mode damper corresponding to the target humidity can be quickly obtained. If the first humidity is within the second sub - preset humidity range, it means that the first humidity is relatively large. The operation mode of the mode damper is set to the window - blowing mode, which can prevent the windshield of the vehicle from fogging up. Under the condition of effectively adjusting the humidity, the driving safety of the vehicle can also be improved.

[0121] For example, if the first humidity is within the second preset humidity range, the operation mode of the recirculation damper is set to the internal recirculation mode. If the first humidity is within the second preset humidity range, it means that the humidity is relatively large. In this case, by adjusting the opening degree of the recirculation damper, the humidity adjustment requirement can no longer be met. Therefore, the operation mode of the recirculation damper can be set to the internal recirculation mode, and the compressor speed calculated by the foregoing embodiment is used to control the compressor to refrigerate and dehumidify. Thus, the required humidity adjustment requirement can be achieved, and the energy consumption generated by adjusting the opening degree of the recirculation damper can be saved.

[0122] Step 209, if the first humidity is within the first humidity range or the second humidity range, the blower air volume corresponding to the first humidity is obtained according to the corresponding relationship between the preset humidity and the preset blower air volume, so as to control the operation of the blower of the air - conditioner according to the blower air volume.

[0123] For example, the corresponding relationship between the preset blower air volume and the preset humidity can be shown in Table 1.

[0124] Table 1

[0125] -50 -30 -10 10 30 50 70 90 <![CDATA[RH0]]> 21 13 7 2 6 11 16 21 <![CDATA[RH0+5]]> 23 15 9 2 8 13 18 23 <![CDATA[RH0+10]]> 25 17 11 4 10 15 20 25 <![CDATA[RH0+15]]> 27 19 13 6 12 17 22 27 ······ ······ ······ ······ ······ ······ ······ ······ ······ <![CDATA[RH3]]> 30 23 17 10 16 21 26 30

[0126] Referring to Table 1, the blower air volume first decreases and then increases with the increase of TAO, and increases with the increase of RH.

[0127] In this embodiment, according to the corresponding relationship between the preset blower air volume and the preset humidity, the blower air volume corresponding to the first humidity is obtained, so as to control the operation of the blower of the air - conditioner according to the blower air volume. The blower speed can be quickly and accurately obtained. Based on the quick adjustment of the blower, the humidity can be quickly adjusted to the required humidity.

[0128] For example, the method of this embodiment may further include the following steps:

[0129] Step 210, obtain the third ratio between the preset saturated steam pressure threshold and the first saturated steam pressure.

[0130] Among them, the first saturated vapor pressure is the saturated vapor pressure corresponding to the first temperature. The preset saturated vapor pressure threshold is the saturated vapor pressure threshold when the windshield of the vehicle gets fogged up.

[0131] Exemplarily, calculate the third ratio RH3 between the humidity threshold and the first saturated vapor pressure according to formula (16):

[0132]

[0133] Where P d is the preset saturated vapor pressure threshold inside the vehicle when the windshield of the vehicle gets fogged up; P cab is the first saturated vapor pressure corresponding to the first temperature T cab .

[0134] Step 211, obtain the third difference between the third ratio and the preset humidity.

[0135] The third difference can be expressed as: RH3 - RH0.

[0136] Step 212, obtain the third product of the third difference and the second preset coefficient, and the fourth product of the third difference and the third preset coefficient.

[0137] The third product of the third ratio and the second preset coefficient can be expressed as:

[0138] The fourth product of the third ratio and the third preset coefficient can be expressed as:

[0139] Step 213, obtain the first humidity critical value according to the second summation result of the preset humidity and the third product, and obtain the second humidity critical value according to the third summation result of the preset humidity and the fourth product;

[0140] Calculate the first humidity critical value RH1 according to formula (17):

[0141]

[0142] Exemplarily, calculate the second humidity critical value RH2 according to formula (18):

[0143]

[0144] Step 214, construct the first preset humidity range according to the preset humidity and the first humidity critical value;

[0145] The first preset humidity range is [RH0, RH1].

[0146] Step 215: Construct a first sub - preset humidity range according to the first humidity critical value and the second humidity critical value;

[0147] The first sub - preset humidity range is [RH1, RH2].

[0148] Step 216: Construct a second sub - preset humidity range according to the second humidity critical value.

[0149] The second sub - preset humidity range is that the humidity is greater than RH2.

[0150] Furthermore, this embodiment further includes a third preset humidity range where the humidity is less than RH0. When the first humidity is within the third preset humidity range, obtain the opening degree of the circulation air door and the operating mode of the mode air door according to the TAO value, and obtain the compressor speed and the blower speed according to the TAO value.

[0151] Exemplarily, according to the above - mentioned embodiment, the humidity can be divided into four preset humidity ranges. The humidity level corresponding to the third preset humidity range is comfortable, the humidity level corresponding to the first preset humidity range is low humidity, the humidity level corresponding to the first sub - preset humidity range is medium humidity, and the humidity level corresponding to the second sub - preset humidity range is high humidity. The specific division results are shown in Table 2.

[0152] Table 2

[0153] Relative humidity inside the vehicle <![CDATA[RH < RH0]]> <![CDATA[RH0<RH<RH1]]> <![CDATA[RH1<RH<RH2]]> <![CDATA[RH>RH2]]> Humidity level Comfortable Low humidity Medium humidity High humidity

[0154] In this embodiment, obtain the third ratio between the preset saturated vapor pressure threshold and the first saturated vapor pressure, obtain the third difference between the third ratio and the preset humidity, obtain the third product of the third difference and the second preset coefficient, and obtain the first humidity critical value according to the second summation result of the third product and the preset humidity; and obtain the fourth product of the third difference and the third preset coefficient, and obtain the second humidity critical value according to the third summation result of the fourth product and the preset humidity. According to the preset humidity, the first humidity critical value and the second humidity critical value, the humidity can be accurately divided into three preset humidity ranges: the first preset humidity range, the first sub - preset humidity range and the second sub - preset humidity range. Dividing the humidity into at least three preset humidity ranges for subsequent comparison of the first humidity inside the vehicle with each preset humidity range, and according to the comparison result, determine which preset humidity range interval the first humidity falls into, and adopt the corresponding humidity adjustment strategy to adjust the humidity for the determined preset humidity range interval. Thus, effective and accurate humidity adjustment can be achieved.

[0155] This application provides a humidity control method. In this embodiment, taking the vehicle as an example of a vehicle for exemplary illustration. Refer to Figure 4 , the method includes:

[0166] Step S8, determine whether the first humidity is within a first sub-preset humidity range. If so, enter step S9; otherwise, enter step S11.

[0167] Step S9, set the working mode of the circulation air damper to the internal circulation mode, and obtain the operating mode of the mode air damper according to the corresponding relationship between the preset operating mode of the mode air damper and the preset humidity.

[0168] Step S10, calculate the engine speed according to the energy conservation criterion, and obtain the air speed of the blower through the corresponding relationship between the preset air volume of the blower and the preset humidity.

[0169] The method of this step has been described in the foregoing embodiments and will not be elaborated here.

[0170] When the RH inside the vehicle is greater than RH1 and less than RH2, the circulation air door is in the recirculation mode, the mode air door is controlled according to the TAO value, the target speed of the compressor is calculated based on the law of conservation of energy, and the air volume of the blower is obtained according to the corresponding relationship between the preset blower air volume and the preset humidity.

[0171] Step S11: Set the working mode of the circulation air door to the recirculation mode and set the working mode of the mode air door to the window-blowing mode.

[0172] Step S12: Calculate the engine speed according to the law of conservation of energy and obtain the blower air speed through the corresponding relationship between the preset blower air volume and the preset humidity.

[0173] When the RH inside the vehicle is greater than RH2, determine that the opening of the circulation air door is in the recirculation mode, the mode air door is in the window-blowing mode, the target speed of the compressor is calculated based on the law of conservation of energy, and the air volume of the blower is controlled by looking up a table.
