Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0051] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0052] In conventional fresh air conditioning systems, the carbon dioxide concentration detection device is usually located at the return air vent of the indoor unit. Because carbon dioxide is heavier than air, the carbon dioxide concentration detected at the return air vent is usually much lower than the actual concentration in the environment, making it inaccurate and unable to introduce fresh air in a timely manner according to the user's actual needs. Furthermore, the introduced fresh air cannot be efficiently delivered to the vicinity of the user's head, resulting in low fresh air utilization.

[0053] To address the aforementioned technical problems, this application provides an air conditioning fresh air assembly, an air conditioner, an air conditioning fresh air control method, and an apparatus. By installing an air conditioning fresh air assembly in the indoor unit, the fresh air duct within the assembly includes a retractable fresh air section that can be automatically / manually controlled to extend and retract. A fresh air outlet is located on the outer side of the end of the retractable fresh air section. The fresh air outlet is equipped with a fresh air guide plate for adjusting the direction of the fresh air flow. The fresh air guide plate, through angle adjustment, controls the fresh air to be dispersed in all directions, preventing the fresh air from blowing directly onto the user's head. Simultaneously, the speed of the fresh air fan in the air conditioning fresh air assembly can be adjusted to meet different fresh air delivery range requirements, i.e., fresh air volume requirements.

[0054] For details, see Figure 1 , Figure 1 The schematic diagram of the structure of the air conditioning fresh air assembly provided in the embodiment of this application shows that the air conditioning fresh air assembly 1 includes: a fresh air duct 10, one end of which is provided with a fresh air inlet 100 and the other end of which is provided with a fresh air outlet 101, the other end of which includes a retractable fresh air section 102 for adjusting the position of the fresh air outlet 101; and a fresh air guide plate 11, which is located corresponding to the fresh air outlet 101 for adjusting the direction of fresh air outlet.

[0055] It is understood that the retractable fresh air section 102 is a part of the fresh air duct 10. The retractable fresh air section can be detachably connected to the duct body of the fresh air duct 10, or it can be fixedly connected to the duct body of the fresh air duct 10. The retractable fresh air section 102 can be an automatically retractable hose reel, a retractable duct controlled by a linkage mechanism, etc. Specifically, in use, the retractable fresh air section 102 can be manually stretched by the user to control its extension or retraction, or it can be controlled by a drive device that communicates with the air conditioner. The specific structure of the retractable fresh air section 102 is not specifically limited in this application, but is exemplarily provided as follows:

[0056] In one embodiment of this application, the retractable fresh air section 102 includes a driving device and a telescopic pipe section driven by the driving device. After receiving the telescopic parameters of the retractable fresh air section 102, the driving device controls the telescopic pipe section to extend and retract according to the telescopic parameters, thereby realizing the telescopic control of the retractable fresh air section 102 and further realizing the adjustment of the position of the fresh air outlet 101.

[0057] In another embodiment of this application, the retractable fresh air section 102 includes a retractable pipe section, and the retractable fresh air section 102 is adjustable by manual stretching.

[0058] It is understood that the other end of the fresh air duct 10 with fresh air outlet 101 includes a retractable fresh air section 102 for adjusting the position of the fresh air outlet 101. That is, the retractable fresh air section 102 can be arranged at intervals from the fresh air outlet 101, and the fresh air outlet 101 can also be arranged on the retractable fresh air section 102. That is, the free end of the retractable fresh air section 102 is the fresh air outlet 101.

[0059] It is understood that the fresh air guide plate 11 is located at the fresh air outlet 101 to adjust the direction of fresh air output. The specific arrangement of the fresh air guide plate 11 is not limited in this application; an example is provided below:

[0060] In one embodiment of this application, the fresh air outlet 101 is provided with a mounting bracket for installing a fresh air plate, the mounting bracket is connected to the inner wall of the fresh air duct 10, and the fresh air guide plate 11 is installed on the mounting bracket.

[0061] In another embodiment of this application, the fresh air guide plate 11 is semi-enclosed around the fresh air outlet 101, and the fresh air outlet 101 is hinged to adjust the air outlet direction of the fresh air outlet 101.

[0062] It is understandable that the fresh air duct 10 is equipped with a fresh air fan 13, which is located at one end corresponding to the fresh air inlet 100. Specifically, the fresh air outlet 101 is generally located outdoors, while the fresh air outlet 101 is located indoors where the air conditioner is operating. The operation of the fresh air fan 13 controls the outdoor airflow to flow from the fresh air inlet 100 through the fresh air duct 10, and then outputs it to the indoors through the fresh air outlet 101, thereby achieving the renewal of indoor air.

[0063] It is understood that in some embodiments of this application, an air purification device is provided at the fresh air inlet 100 to purify the incoming fresh air and enhance the quality of the fresh air.

[0064] For details, see Figure 1 In one embodiment of this application, the fresh air duct 10 is provided with an exhaust duct 12, and the outer wall of the exhaust duct 12 and the inner wall of the fresh air duct 10 are spaced apart to form a fresh air channel. One end of the exhaust duct 12 is provided with an exhaust outlet 120, and the other end of the exhaust duct 12 is provided with an exhaust inlet 121.

[0065] It is understood that the fresh air duct is used to provide a fresh air circulation path. It is understood that a connecting rod may be provided between the outer wall of the exhaust duct and the inner wall of the fresh air duct 10 to ensure the stability of the exhaust duct. It is understood that in some other embodiments of this application, a connecting rod may not be provided between the outer wall of the exhaust duct and the inner wall of the fresh air duct 10. The fresh air duct is formed by fixing the positions of the exhaust duct and the fresh air duct 10 during installation.

[0066] It is understood that the fresh air outlet 101 and the exhaust air inlet 121 are located on the same side of the fresh air duct 10 / exhaust air duct 12, and the exhaust air outlet 120 and the fresh air inlet 100 are located on the same side of the fresh air duct 10 / exhaust air duct 12. The fresh air outlet 101 and the exhaust air inlet 121 can be separated by a baffle, or the exhaust air inlet 121 can be set to protrude from the fresh air outlet 101 to achieve isolation between fresh air and exhaust air. Similarly, the arrangement scheme of the exhaust air outlet 120 and the fresh air inlet 100 can also refer to the arrangement scheme of the fresh air outlet 101 and the exhaust air inlet 121 to achieve isolation between fresh air and exhaust air.

[0067] It is understandable that by setting the air conditioning fresh air component 1 to include an exhaust duct 12 and placing the exhaust duct 12 inside the fresh air duct 10, an indoor exhaust gas exhaust channel is formed, ensuring that the polluted air generated when the user breathes is discharged in a timely and rapid manner, thereby guiding the fresh air blown out from all sides of the fresh air duct outlet to flow towards the user's head position, forming an air flow circulation, and ensuring the air quality at the user's head position; at the same time, the fresh air intake and exhaust are carried out simultaneously.

[0068] It is understood that, in one embodiment of this application, the fresh air duct is provided with a fresh air heat exchange device to achieve heat exchange of fresh air. The fresh air heat exchanger controls the temperature of the incoming fresh air to be slightly lower than the ambient temperature, ensuring that the fresh air automatically sinks after being blown out and flows towards the user's head, further improving the utilization rate of fresh air. At the same time, it ensures that the temperature difference between the fresh air and the ambient temperature is controlled within a certain range to avoid excessive temperature difference affecting user comfort.

[0069] Furthermore, based on the above implementation plan, please refer to... Figure 1 The fresh air guide plate 11 is arranged around the exhaust inlet 121 and hinged to the outer wall of the exhaust duct 12, and the free end of the fresh air guide plate 11 protrudes from the fresh air outlet 101.

[0070] It is understood that the end of the fresh air guide plate 11 that is hinged to the outer wall of the exhaust duct 12 may be provided with an electric hinge device. The hinge with the outer wall of the exhaust duct 12 is achieved by the electric hinge device. For example, the electric hinge device may include a hinge structure and a drive device (such as a motor) for driving the hinge structure. In use, the drive device receives the position parameters sent by the air conditioner and drives the hinge structure to rotate according to the position parameters to reach the position corresponding to the position parameters, thereby adjusting the direction of the fresh air outlet.

[0071] It is understood that an exhaust fan 14 is installed in the exhaust duct 12, and the exhaust air volume can be controlled by adjusting the target fan parameters of the exhaust fan 14.

[0072] Understandably, see Figure 1 The free end of the fresh air guide plate 11 moves closer to or further away from the fresh air outlet 101 to adjust the direction of the fresh air outlet.

[0073] For details, see Figure 1 In this embodiment of the application, the fresh air guide plate 11 includes a first air guide baffle 110 and a second air guide baffle 111. One end of the first air guide baffle 110 is hinged to the outer wall of the exhaust duct 12, and the other end of the first air guide baffle 110 is movably connected to the second air guide baffle 111.

[0074] It is understood that the other end of the first air guide baffle 110 and the second air guide baffle 111 can be hinged or detachable. Specifically, by setting the first air guide baffle 110 and the second air guide baffle 111, the fresh air outlet 101 and the exhaust air inlet 121 can be better isolated.

[0075] Specifically, the above-described embodiments of this application provide an air conditioning fresh air assembly 1, which includes: a fresh air duct 10, one end of which has a fresh air inlet 100, and the other end of which has a fresh air outlet 101. The other end of the fresh air duct 10 with the fresh air outlet 101 includes a retractable fresh air section 102 for adjusting the position of the fresh air outlet 101; and a fresh air guide plate 11, located at the fresh air outlet 101 for adjusting the direction of fresh air flow. This solution, by setting the fresh air guide plate 11 and the retractable fresh air section 102 at the corresponding location of the fresh air outlet 101 in the fresh air duct, allows users to flexibly adjust the direction and position of fresh air intake, thereby improving fresh air intake performance.

[0076] Furthermore, based on the above implementation scheme, this application also provides an air conditioner, which includes the fresh air component 1 described in any of the above implementation schemes.

[0077] Specifically, in one embodiment of this application, see [link to relevant documentation]. Figure 2 , Figure 2 The present application provides a schematic diagram of the structure of an air conditioner, which includes an indoor unit assembly 2, an outdoor unit assembly 3, a compressor assembly 4, and a fresh air assembly 1 as described in any of the above embodiments. The indoor unit assembly 2, the outdoor unit assembly 3, the compressor assembly 4, and the fresh air assembly 1 are communicatively connected and connected by refrigerant.

[0078] It is understood that the air conditioner may also include a carbon dioxide concentration detection device for detecting carbon dioxide concentration, a location detection device for detecting user location, etc., wherein the location detection device may be, for example, an infrared detection device, a user biometric information collection device, etc.

[0079] Furthermore, based on the above implementation scheme, this application provides an air conditioning fresh air control method, applied to the air conditioner described in the above implementation scheme, see [link to relevant documentation]. Figure 3 , Figure 3 This is a schematic flowchart of an embodiment of the air conditioning fresh air control method provided in this application, including steps S301-S304:

[0080] S301. Obtain the indoor carbon dioxide concentration and the fresh air status parameters of the air conditioner corresponding to the air conditioner.

[0081] The fresh air status parameters include fresh air on and fresh air off. It can be understood that the fresh air status parameters can be determined by the current working parameters of the air conditioner.

[0082] It is understandable that the air conditioner can detect the indoor carbon dioxide concentration through its built-in carbon dioxide concentration detection device, or through a carbon dioxide concentration detection device that communicates with the air conditioner, to obtain the indoor carbon dioxide concentration corresponding to the air conditioner.

[0083] Specifically, the air conditioner can obtain the indoor carbon dioxide concentration and the fresh air status parameters of the air conditioner after detecting that the air conditioner has been running for a preset time. Alternatively, it can detect the indoor carbon dioxide concentration of the air conditioner when the air conditioner is turned on, and obtain the fresh air status parameters of the air conditioner when the indoor carbon dioxide concentration is detected to be greater than a preset concentration threshold.

[0084] S302. Based on the fresh air status parameters and the relationship between the indoor carbon dioxide concentration and the preset carbon dioxide concentration, determine the target fresh air parameters. The target fresh air parameters include the target fan parameters of the fresh air fan in the fresh air duct and the position parameters of the fresh air guide plate.

[0085] The target fan parameters can include the fan windshield, fan speed, etc.

[0086] The position parameter can be the driving parameter that controls the rotation of the fresh air guide plate, or the angle of the fresh air guide plate, etc.

[0087] Specifically, after obtaining the indoor carbon dioxide concentration and the fresh air status parameters of the air conditioner, the air conditioner compares the indoor carbon dioxide concentration with the preset carbon dioxide concentration, and determines the target fresh air parameters based on the relationship between the indoor carbon dioxide concentration and the preset carbon dioxide concentration, as well as the fresh air status parameters.

[0088] S303. Control the fresh air fan to operate according to the target fan parameters, and adjust the position parameters of the fresh air guide plate according to the position parameters.

[0089] Specifically, after determining the target fresh air parameters, the air conditioner controls the operation of the fresh air fan in the fresh air duct of the air conditioner fresh air component according to the target fan parameters in the target fresh air parameters, thereby adjusting the fresh air volume, and controls the guide plate angle of the fresh air guide plate in the air conditioner fresh air component according to the position parameters in the target fresh air parameters.

[0090] S304. According to the wind direction determined by the location parameters, the fresh air volume corresponding to the target fan parameters is output through the fresh air duct equipped with a retractable fresh air section.

[0091] Furthermore, after controlling the fresh air fan to operate according to the target fan parameters and adjusting the position parameters of the fresh air guide plate according to the position parameters, the air conditioner outputs the fresh air volume corresponding to the target fan parameters through the fresh air duct with a retractable fresh air section according to the air direction determined by the position parameters. Fresh air output can be achieved by opening the damper of the fresh air duct.

[0092] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 4 , Figure 4 A flowchart illustrating one implementation scheme for determining target fresh air parameters in the air conditioning fresh air control method provided in this application embodiment includes steps S401-S403:

[0093] S401. If the indoor carbon dioxide concentration is less than the preset carbon dioxide concentration and the fresh air status parameter is fresh air on, then obtain the outlet fresh air temperature and outlet indoor temperature corresponding to the fresh air outlet in the fresh air component.

[0094] Among them, the fresh air temperature at the outlet, that is, the fresh air temperature at the fresh air outlet of the air conditioner, can be obtained by a temperature detector located at the fresh air outlet.

[0095] The "outlet indoor temperature" refers to the indoor ambient temperature near the fresh air outlet of the air conditioner. It can be understood that the definition of "near the fresh air outlet" can be customized according to the actual application environment. For example, if the area within one meter of the fresh air outlet is defined as the "near the fresh air outlet," then the "outlet indoor temperature" is the indoor ambient temperature within one meter of the fresh air outlet. This temperature can be collected by a temperature detection sensor installed within one meter of the fresh air outlet.

[0096] Specifically, after obtaining the indoor carbon dioxide concentration and the fresh air status parameters of the air conditioner, the air conditioner compares the indoor carbon dioxide concentration with the preset carbon dioxide concentration. If the indoor carbon dioxide concentration is less than the preset carbon dioxide concentration, it means that the indoor carbon dioxide concentration is not high. At this time, the fresh air status parameters of the air conditioner are determined. If the fresh air status parameters indicate that the fresh air is on, that is, the air conditioner's fresh air is on, the outlet fresh air temperature and the outlet indoor temperature are obtained.

[0097] S402. Based on the temperature difference between the outlet fresh air temperature and the outlet indoor temperature, determine the target fan parameters of the fresh air fan in the fresh air duct of the air conditioner and the position parameters of the fresh air guide plate of the air conditioner.

[0098] Specifically, after obtaining the outlet fresh air temperature and the outlet indoor temperature, the air conditioner calculates the temperature difference between the outlet fresh air temperature and the outlet indoor temperature. This application does not specifically limit the implementation method of determining the target fan parameters of the fresh air fan in the air conditioner's fresh air duct and the position parameters of the air conditioner's fresh air guide plate; an example is provided:

[0099] In one embodiment of this application, after calculating the temperature difference between the outlet fresh air temperature and the outlet indoor temperature, the air conditioner looks up a preset mapping table corresponding to the temperature difference, location, and fan parameters to obtain the target fan parameters and location parameters corresponding to the temperature difference, thereby obtaining the target fan parameters of the fresh air fan in the fresh air duct of the air conditioner and the location parameters of the fresh air guide plate of the air conditioner.

[0100] In another embodiment of this application, after calculating the temperature difference between the outlet fresh air temperature and the outlet indoor temperature, the air conditioner compares the temperature difference with a preset temperature difference threshold. If the temperature difference is greater than the preset temperature difference threshold, it obtains the current fan parameters and preset fan adjustment parameters, obtains the target fan parameters based on the current fan parameters and preset fan adjustment parameters, obtains the current position parameters and preset position adjustment parameters of the fresh air guide plate, and obtains the position parameters based on the current position parameters and preset position adjustment parameters.

[0101] S403. Set the target fan parameters, the position parameters, and the minimum exhaust parameters of the exhaust fan in the exhaust duct of the air conditioner as the target fresh air parameters.

[0102] The minimum exhaust parameters may be the minimum wind speed of the exhaust fan, the minimum wind speed, and / or the opening degree of the damper in the exhaust duct, etc.

[0103] Specifically, after obtaining the target fan parameters and location parameters, the air conditioner acquires the minimum exhaust parameters of the exhaust fan in the air conditioner's exhaust duct, and sets the target fan parameters, the location parameters, and the minimum exhaust parameters of the exhaust fan in the air conditioner's exhaust duct as the target fresh air parameters.

[0104] By controlling the fresh air output based on the temperature difference between the outlet fresh air temperature and the outlet indoor temperature, the temperature of the delivered fresh air is controlled to be slightly lower than the ambient temperature near the fresh air outlet. This ensures that the fresh air automatically sinks after being blown out and flows towards the user's head, further improving the utilization rate of fresh air. At the same time, it ensures that the temperature difference between the fresh air temperature and the ambient temperature near the fresh air outlet is controlled within a certain range to avoid excessive temperature difference affecting user comfort.

[0105] It is understood that, in another embodiment of this application, after obtaining the indoor carbon dioxide concentration and the fresh air status parameters of the air conditioner, the air conditioner compares the indoor carbon dioxide concentration with the preset carbon dioxide concentration. If the indoor carbon dioxide concentration is less than the preset carbon dioxide concentration, it indicates that the indoor carbon dioxide concentration is not high. At this time, the fresh air status parameters of the air conditioner are judged. If the fresh air status parameters are that the fresh air is off, the target fresh air parameter is determined to be zero. That is, the fresh air is controlled not to start, the fresh air loss is reduced, and the fresh air can be adaptively adjusted according to the user's fresh air demand.

[0106] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 5 , Figure 5 A schematic flowchart illustrating another implementation scheme for determining the target fresh air parameters in the air conditioning fresh air control method provided in this application embodiment, including steps S501-S502:

[0107] S501. If the indoor carbon dioxide concentration is not less than the preset carbon dioxide concentration, and the fresh air status parameter is fresh air off, then obtain the maximum fresh air parameter of the fresh air fan in the fresh air duct of the air conditioner, the maximum air guiding position of the fresh air guide plate of the air conditioner, and the maximum exhaust parameter of the exhaust fan in the exhaust duct of the air conditioner.

[0108] The maximum airflow direction is the position of the fresh air guide plate corresponding to the maximum fresh air output.

[0109] The exhaust parameters refer to the maximum fan speed or maximum rotation speed of the fresh air fan.

[0110] Specifically, after obtaining the indoor carbon dioxide concentration and the fresh air status parameters of the air conditioner, the air conditioner compares the indoor carbon dioxide concentration with the preset carbon dioxide concentration. If the indoor carbon dioxide concentration is less than the preset carbon dioxide concentration, it indicates that the indoor carbon dioxide concentration is high. At this time, the maximum air guiding position of the fresh air guide plate of the air conditioner and the maximum exhaust parameters of the exhaust fan in the exhaust duct of the air conditioner are obtained.

[0111] S502. Set the maximum fresh air parameter, the maximum air guiding position, and the maximum exhaust air parameter as the target fresh air parameter.

[0112] Furthermore, the air conditioner sets the maximum fresh air parameter, the maximum air guide position, and the maximum exhaust parameter as the target fresh air parameter to control the air conditioner to introduce fresh air with the maximum fresh air intake capacity, thereby rapidly reducing the indoor carbon dioxide concentration.

[0113] Furthermore, based on the above implementation plan, see [link to relevant documentation]. Figure 6 , Figure 6This is a flowchart illustrating one implementation scheme of the fresh air output in the air conditioning fresh air control method provided in this application, including steps S601-S603:

[0114] S601. Identify the target user and determine the distance between the target user and the fresh air outlet of the air conditioner.

[0115] The target user can be any user in the room, or a user whose information is pre-stored among the users in the room. It is understood that the target user can be identified by an infrared detection device that detects the user closest to the fresh air outlet, or the air conditioner can collect the user's biological information through a biological information collection device, match the user's biological information with a user biological information database, and find the target user's biological information contained in the user biological information database. That is, the user corresponding to the target user's biological information is the target user. It is understood that the biological information can be a face, fingerprint, voice, etc.

[0116] Specifically, the distance value, that is, the distance between the target user and the fresh air outlet of the air conditioner, can be obtained by a rangefinder installed at the fresh air outlet.

[0117] S602. Determine the extension parameters of the extendable fresh air section based on the distance value.

[0118] Specifically, after obtaining the distance value, the air conditioner determines the expansion parameters of the expandable fresh air section based on the distance value. This application does not specifically limit the implementation method, but exemplarily:

[0119] In one embodiment of this application, after obtaining the distance value, the air conditioner searches a preset mapping table corresponding to the distance and parameters to obtain the scaling parameters corresponding to the distance value.

[0120] In another embodiment of this application, after obtaining the distance value, the air conditioner compares the distance value with a preset distance threshold. If the distance value is greater than the preset distance threshold, the current extension parameter is added to a preset adjustment parameter to obtain the extension parameter. If the distance value is less than the preset distance threshold, the current extension parameter is subtracted from the preset adjustment parameter to obtain the extension parameter.

[0121] S603. Control the retractable fresh air section to extend and retract according to the extension parameters, and control the fresh air duct to output the fresh air volume corresponding to the target fan parameters according to the wind direction determined by the position parameters.

[0122] Specifically, the air conditioner controls the retractable fresh air section to extend and retract according to the extension parameters, so as to control the fresh air duct to output the fresh air volume corresponding to the target fan parameters according to the wind direction determined by the position parameters.

[0123] This application provides an air conditioning fresh air control method applied to an air conditioner equipped with the fresh air component described in any of the above-mentioned embodiments.

The method controls the fresh air fan to operate according to the target fan parameters and adjusts the position parameters of the fresh air guide plate according to the position parameters. The method outputs the fresh air volume corresponding to the target fan parameters through a fresh air duct with a retractable fresh air section, according to the airflow direction determined by the position parameters. This solution improves fresh air performance by setting a fresh air guide plate and a retractable fresh air section at the fresh air outlet of the fresh air duct, and adjusting the fresh air volume and the position of the fresh air guide plate in conjunction with the indoor carbon dioxide concentration and fresh air status parameters.

[0139] Set the maximum fresh air parameter, the maximum air guiding position, and the maximum exhaust air parameter as the target fresh air parameter.
