[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] The existing methods of suppressing structural resonance mainly include the following two methods: first, changing the frequency characteristics of the excitation source to make it staggered with the structural modal frequency; second, using high damping materials or additional damping to reduce the resonance amplitude. In the first method, changing the excitation source is often limited by the operation of the machine and equipment, and the potential for adjustment in the actual process is limited; the second method can only reduce the sound radiation intensity of the plate structure to a certain extent.

[0032] The present invention provides a control method for an air conditioner. The panel of the air conditioner adopts a composite alloy plate. The composite alloy plate can specifically be a shape memory alloy (SMA) gradient composite plate. SMA is a kind of intelligent material, which has the characteristics of temperature control and magnetic control. The upper and lower surface plates of the composite sandwich panel are orthogonally embedded with SMA fiber filaments containing tensile prestrain, and the core layer is an isotropic gradient functional structure composed of graphite and epoxy resin. As the temperature increases, SMA transforms from a martensite phase to an austenite phase, resulting in an increase in the elastic modulus and recovery stress of SMA. When the volume fraction of the SMA fiber in the surface layer of the composite sandwich panel and the SMA prestrain increase, the natural frequency of the composite sandwich panel increases.

[0033] Figure 1 It is a method schematic diagram of an embodiment of the air conditioner control method provided by the present invention.

[0034] like Figure 1 As shown, according to an embodiment of the present invention, the air conditioner control method at least includes step S110, step S120 and step S130.

[0035] Step S110, obtaining a pre-established correspondence between the operating frequency of the air conditioner and the panel temperature.

[0036] The corresponding relationship may specifically include: the panel temperature with the best sound quality when the air conditioner is running at different frequencies.

[0037] In a specific implementation, the sound quality of the panel at different panel temperatures when the air conditioner is running at different frequencies can be obtained in advance through experimental testing, and the panel temperature with the best sound quality when the air conditioner is running at different frequencies can be obtained.

[0038] Figure 2 A schematic diagram of steps of a specific implementation method of pre-establishing a corresponding relationship between the operating frequency of the air conditioner and the panel temperature according to the present invention is shown.

[0039] like Figure 2 As shown, in a specific implementation manner, a corresponding relationship between the operating frequency of the air conditioner and the panel temperature is pre-established, through the following steps S1 to S3:

[0040] Step S1 : constructing a sound quality model of the panel of the air conditioner, and obtaining sound quality parameter values ​​corresponding to different parameter values ​​of k material parameters of the panel when the air conditioner is running at different frequencies.

[0041] Specifically, the panel of the air conditioner may include more than one sound quality parameter. A corresponding sound quality parameter model may be constructed for each sound quality parameter. The sound quality model may include more than one sound quality parameter model. In a specific implementation, the sound quality parameters include: loudness F N , sharpness F S , Roughness F R Therefore, the sound quality model of the panel may include a loudness model, a sharpness model, and a roughness model. For example, the loudness model F N , sharpness model F S , Roughness Model F R They can be shown as follows:

[0042]

[0043] The k material parameters of the panel are used as influencing factors of the sound quality model, that is, the sound quality model includes k material parameter influencing factors x1, x2, ..., x k That is to say, the k material parameters x1, x2, ..., x k The parameter values ​​of the k material parameters of the panel are different, and the corresponding sound quality parameters are also different. The sound quality parameter values ​​corresponding to the different parameter values ​​of the k material parameters of the panel when the air conditioner is running at different frequencies can be obtained through experimental testing. That is, when the air conditioner is running at different frequencies, the parameter values ​​of the k material parameters are different, and the corresponding sound quality parameter values ​​are different. The loudness model F N , sharpness model F S , Roughness Model F R Specifically, it can be loudness F N , sharpness F S , Roughness F R The linear expressions of the k material parameters can be obtained by linear fitting.

[0044] Step S2, obtaining the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the parameter values ​​of the k material parameters of the panel at different panel temperatures obtained in advance through experimental tests.

[0045] Specifically, the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the parameter values ​​of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies are tested in advance by experiments. For example, the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies can be obtained by simulation testing.

[0046] Step S3, establishing a corresponding relationship between the operating frequency of the air conditioner and the panel temperature based on the constructed sound quality model, the acquired sound quality parameter values ​​corresponding to different parameter values ​​of k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the parameter values ​​of the k material parameters.

[0047] Figure 3 FIG. 1 is a flowchart showing a specific implementation of establishing a corresponding relationship between the operating frequency of the air conditioner and the panel temperature according to the present invention. Figure 3 As shown, in a specific implementation, establishing the corresponding relationship between the operating frequency of the air conditioner and the panel temperature includes the following steps S31 to S33:

[0048] Step S31, based on the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the values ​​of the k material parameters of the panel at different panel temperatures, a first preset algorithm is used to fit the relationship between the panel temperature of the panel when the air conditioner is running at different frequencies and the k material parameters.

[0049] For example, according to the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, the panel temperature when the sound quality is optimal and the values ​​of the k material parameters are determined (the mode is the inherent characteristic of the panel material, and the sound quality changes with the change of the mode. Therefore, by testing the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, the panel temperature when the sound quality is optimal when the air conditioner is running at different frequencies and the values ​​of the k material parameters can be determined from the sound power and mode). Through linear fitting, the relationship between the panel temperature y when the sound quality of the panel is optimal when the air conditioner is running at different frequencies and the k material parameters x1~xk is a linear relationship: y=a+bx, where x is the parameter value of the k material parameters x1~xk, and y is the parameter value of the k material parameters x1~xk. The first preset algorithm can be, for example, linear interpolation.

[0050] Step S32, according to the sound quality model and the sound quality parameter values ​​corresponding to different parameter values ​​of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, a relationship between the panel temperature of the panel when the air conditioner is running at different frequencies and the sound quality parameter of the air conditioner is obtained by fitting through a second preset algorithm.

[0051] For example, through linear fitting, the relationship between the panel temperature y of the panel and the sound quality F of the air conditioner when the air conditioner is running at different frequencies is obtained as follows: F = c + dy, where y is: y1 ~ yk, and F is: loudness FN , sharpness F S , Roughness F R ; The second preset algorithm can specifically be the least squares method.

[0052] In the above formula, a, b, c, and d all have values ​​of k, which are substituted into the initial values ​​corresponding to x1~xk.

[0053] Step S33, iteratively obtain the corresponding relationship between the operating frequency of the air conditioner and the panel temperature according to the obtained relationship between the panel temperature and the k material parameters and the relationship between the panel temperature and the sound quality parameter of the air conditioner when the air conditioner is running at different frequencies.

[0054] Specifically, the panel temperature will affect the k material parameters x1, x2, ..., x k By assigning the initial temperature, there will be an initial parameter value X (including initial parameter values ​​of x1~xk). These material parameters affect the inherent characteristics of the panel. When the panel temperature changes, the material parameters change, and the inherent characteristics of the panel (i.e., the mode of the panel) change. When the air conditioner runs at different frequencies, the mode of the panel changes, and the corresponding sound quality changes. According to the experimental test data, the panel temperature and k material parameters x1, x2, ..., xk when the air conditioner runs at different frequencies can be fitted. k The relationship between panel temperature and sound quality (loudness, sharpness and coarseness) is fitted and substituted into the initial value. According to the two relationship equations, the better temperature value and sound quality result when the air conditioner is running at different frequencies can be iterated, that is, the panel temperature with the best sound quality when the air conditioner is running at different frequencies.

[0055] Figure 4 FIG. 2 shows a schematic diagram of a sound quality evaluation system according to the present invention. Figure 4 The sound quality system shown includes a loudness model, a sharpness model, and a roughness model. By assigning initial values ​​to k material parameters and inputting them into simulation software for modal analysis and acoustic analysis, the sound power and mode of the panel corresponding to different parameter values ​​of the k material parameters when the air conditioner is running at different frequencies are obtained.

[0056] Step S120: acquiring, according to the acquired corresponding relationship, a panel temperature corresponding to the current operating frequency of the air conditioner as a target panel temperature.

[0057] Specifically, according to the correspondence between the operating frequency of the air conditioner and the panel temperature, and the current operating frequency of the air conditioner, the panel temperature with optimal sound quality corresponding to the current operating frequency of the air conditioner can be obtained, and the panel temperature is used as the current target panel temperature.

[0058] Step S130, controlling the panel temperature by controlling the temperature control device on the panel so that the panel reaches the target panel temperature.

[0059] Specifically, the temperature control device is controlled according to the current panel temperature and the target temperature, so that the panel reaches the target panel temperature. The temperature control device includes a heating device and a cooling device, and the panel temperature can be controlled by controlling the heating device and the cooling device. A temperature sensor is also provided on the panel, which can detect the panel temperature. According to the panel temperature detected by the temperature sensor, the heating device is controlled to heat the panel or the cooling device is controlled to cool the panel. By controlling the panel temperature, the natural frequency and sound power of the panel at each frequency point can be controlled to obtain the loudness, sharpness and roughness, thereby improving the sound quality of the air conditioner from the perspective of panel noise reduction.

[0060] Figure 5 FIG. 2 is a schematic diagram of another embodiment of the air conditioner control method provided by the present invention. Figure 5 As shown, according to an embodiment of the present invention, the air conditioner control method further includes step S140 and step S150.

[0061] Step S140, receiving an instruction to turn on the augmented reality mode, and turning on the augmented reality mode of the air conditioner when the instruction is received.

[0062] Step S150, displaying the current sound quality parameters of the air conditioner, the current internal operation status of the air conditioner, and the internal dirtiness of the air conditioner by means of augmented reality.

[0063] Specifically, by collecting user gesture images, identifying the gesture start command for turning on the augmented reality mode issued by the user through gestures (for example, raising the hand from the bottom to the top), or receiving the voice start command for turning on the augmented reality mode issued by the user through voice, the augmented reality (AR) mode is turned on, and after entering the AR mode, the parameter values ​​of the current sound quality parameters of the air conditioner, the current internal operation of the air conditioner, and the internal dirtiness of the air conditioner are displayed through AR. The internal dirtiness of the air conditioner includes the distribution of bacteria and / or dust inside the air conditioner. For example, the interior of the air conditioner can be photographed by a camera inside the air conditioner, the image can be displayed through a display screen, and the names of the internal components of the air conditioner, the number and / or distribution location of bacteria, and / or the distribution location and / or coverage area of ​​dust can be displayed on the displayed image through AR.

[0064] For existing air-conditioning display screens, you can use gestures or voice control to turn on the AR mode. The screen will use AR to display the actual operating conditions inside the air conditioner, and display the internal bacteria, dust and other dirt in a numerical way. It can also display the comfort parameters corresponding to the sound quality.

[0065] Optionally, it may also include: reminding the user to use the self-cleaning function before using the air conditioner, and then reminding the user to turn on the self-cleaning function every preset time (for example, every month), and reminding the user to disassemble and clean the air conditioner when the internal dirtiness threshold of the air conditioner reaches the preset threshold. For example, when the area of ​​the internal area of ​​the air conditioner covered by bacteria and / or dust reaches 30%, the user is reminded to do simple disassembly and cleaning; when the area of ​​the internal area of ​​the air conditioner covered by bacteria and / or dust reaches 60%, the user is reminded that a professional is needed to come to the door for disassembly and cleaning services.

[0066] Optionally, it may also include: when the ambient TVOC concentration and / or carbon dioxide concentration reaches a corresponding preset threshold, reminding the user to turn on the fresh air function or open windows for ventilation.

[0067] The present invention also provides a control device for an air conditioner. The panel of the air conditioner adopts a composite alloy plate. The composite alloy plate can specifically be a shape memory alloy (SMA) gradient composite plate. SMA is a kind of intelligent material, which has the characteristics of temperature control and magnetic control. The upper and lower surface plates of the composite sandwich panel are orthogonally embedded with SMA fiber filaments containing tensile prestrain, and the core layer is an isotropic gradient functional structure composed of graphite and epoxy resin. As the temperature increases, SMA transforms from martensite phase to austenite phase, resulting in an increase in the elastic modulus and recovery stress of SMA. When the volume fraction of the SMA fiber in the surface layer of the composite sandwich panel and the SMA prestrain increase, the natural frequency of the composite sandwich panel increases.

[0069] The first acquisition unit 110 is used to acquire a pre-established correspondence between the operating frequency of the air conditioner and the panel temperature.

[0070] The corresponding relationship includes: the panel temperature with the best sound quality when the air conditioner is running at different frequencies.

[0071] In a specific implementation, the sound quality of the panel at different panel temperatures when the air conditioner is running at different frequencies can be obtained in advance through experimental testing, and the panel temperature with the best sound quality when the air conditioner is running at different frequencies can be obtained.

[0072] The control device further includes an establishing unit (not shown) for pre-establishing a corresponding relationship between the operating frequency of the air conditioner and the panel temperature.

[0073] Figure 2 FIG. 1 is a schematic diagram showing a specific implementation method of pre-establishing a corresponding relationship between the operating frequency of the air conditioner and the panel temperature according to the present invention. Figure 2 As shown, in a specific implementation, the establishing unit pre-establishes the corresponding relationship between the operating frequency of the air conditioner and the panel temperature through the following steps S1 to S2:

[0074] Step S1 : constructing a sound quality model of the panel of the air conditioner, and obtaining sound quality parameter values ​​corresponding to different parameter values ​​of k material parameters of the panel when the air conditioner is running at different frequencies.

[0075] Specifically, the panel of the air conditioner may include more than one sound quality parameter. A corresponding sound quality parameter model may be constructed for each sound quality parameter. The sound quality model may include more than one sound quality parameter model. In a specific implementation, the sound quality parameters include: loudness F N , sharpness F S , Roughness F R Therefore, the sound quality model of the panel may include a loudness model, a sharpness model, and a roughness model. For example, the loudness model F N , sharpness model F S , Roughness Model F R They can be shown as follows:

[0076]

[0077] The k material parameters of the panel are used as influencing factors of the sound quality model, that is, the sound quality model includes k material parameter influencing factors x1, x2, ..., x k That is to say, the k material parameters x1, x2, ..., x k The parameter values ​​of the k material parameters of the panel are different, and the corresponding sound quality parameters are also different. The sound quality parameter values ​​corresponding to the different parameter values ​​of the k material parameters of the panel when the air conditioner is running at different frequencies can be obtained through experimental testing. That is, when the air conditioner is running at different frequencies, the parameter values ​​of the k material parameters are different, and the corresponding sound quality parameter values ​​are different. The loudness model F N , sharpness model F S , Roughness Model F R Specifically, it can be loudness F N , sharpness F S , Roughness F R The linear expressions of the k material parameters can be obtained by linear fitting.

[0078] Step S2, obtaining the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the parameter values ​​of the k material parameters of the panel at different panel temperatures obtained in advance through experimental tests.

[0079] Specifically, the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the parameter values ​​of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies are tested in advance by experiments. For example, the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies can be obtained by simulation testing.

[0080] Step S3, establishing a corresponding relationship between the operating frequency of the air conditioner and the panel temperature based on the constructed sound quality model, the acquired sound quality parameter values ​​corresponding to different parameter values ​​of k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, and the parameter values ​​of the k material parameters.

[0081] Figure 3 FIG. 1 is a flowchart showing a specific implementation of establishing a corresponding relationship between the operating frequency of the air conditioner and the panel temperature according to the present invention. Figure 3 As shown, in a specific implementation, establishing the corresponding relationship between the operating frequency of the air conditioner and the panel temperature includes the following steps S31 to S33:

[0082] Step S31, based on the acoustic power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies and the values ​​of the k material parameters of the panel at different panel temperatures, a first preset algorithm is used to fit the relationship between the panel temperature of the panel when the air conditioner is running at different frequencies and the k material parameters.

[0083] For example, the panel temperature when the sound quality is optimal and the values ​​of the k material parameters are determined according to the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies (the mode is the inherent characteristic of the panel material, and the sound quality changes accordingly when the mode changes. Therefore, by testing the sound power and mode of the panel at different panel temperatures when the air conditioner is running at different frequencies, the panel temperature when the sound quality is optimal when the air conditioner is running at different frequencies and the values ​​of the k material parameters can be determined from the sound power and mode). Through linear fitting, the relationship between the panel temperature y when the sound quality of the panel is optimal when the air conditioner is running at different frequencies and the k material parameters x1~xk is a linear relationship: y=a+bx, where x is the parameter value of the k material parameters x1~xk, and y is the parameter value of the k material parameters x1~xk. The first preset algorithm can be, for example, linear interpolation.

[0084] Step S32, according to the sound quality model and the sound quality parameter values ​​corresponding to different parameter values ​​of the k material parameters of the panel at different panel temperatures when the air conditioner is running at different frequencies, a relationship between the panel temperature and the sound quality parameter of the air conditioner when the air conditioner is running at different frequencies is obtained by fitting through a second preset algorithm.

[0085] For example, through linear fitting, the relationship between the panel temperature y of the panel and the sound quality F of the air conditioner when the air conditioner is running at different frequencies is obtained as follows: F = c + dy, where y is: y1 ~ yk, and F is: loudness F N , sharpness F S , Roughness F R ; The second preset algorithm can specifically be the least squares method.

[0086] In the above formula, a, b, c, and d all have values ​​of k, which are substituted into the initial values ​​corresponding to x1~xk.

[0087] Step S33, iteratively obtain the corresponding relationship between the operating frequency of the air conditioner and the panel temperature according to the obtained relationship between the panel temperature and the k material parameters and the relationship between the panel temperature and the sound quality parameter of the air conditioner when the air conditioner is running at different frequencies.

[0088] Specifically, the panel temperature will affect the k material parameters x1, x2, ..., x k By assigning the initial temperature, there will be an initial parameter value X (including initial parameter values ​​of x1~xk). These material parameters affect the inherent characteristics of the panel. When the panel temperature changes, the material parameters change, and the inherent characteristics of the panel (i.e., the mode of the panel) change. When the air conditioner runs at different frequencies, the mode of the panel changes, and the corresponding sound quality changes. According to the experimental test data, the panel temperature and k material parameters x1, x2, ..., xk when the air conditioner runs at different frequencies can be fitted. k The relationship between panel temperature and sound quality (loudness, sharpness and coarseness) is fitted and substituted into the initial value. According to the two relationship equations, the better temperature value and sound quality result when the air conditioner is running at different frequencies can be iterated, that is, the panel temperature with the best sound quality when the air conditioner is running at different frequencies.

[0089] Figure 4 FIG. 2 shows a schematic diagram of a sound quality evaluation system according to the present invention. Figure 4 The sound quality system shown includes a loudness model, a sharpness model, and a roughness model. By assigning initial values ​​to k material parameters and inputting them into simulation software for modal analysis and acoustic analysis, the sound power and mode of the panel corresponding to different parameter values ​​of the k material parameters when the air conditioner is running at different frequencies are obtained.

[0090] The second acquisition unit 120 is configured to acquire, according to the corresponding relationship acquired by the first acquisition unit, a panel temperature corresponding to a current operating frequency of the air conditioner as a target panel temperature.

[0091] Specifically, according to the correspondence between the operating frequency of the air conditioner and the panel temperature, and the current operating frequency of the air conditioner, the panel temperature with optimal sound quality corresponding to the current operating frequency of the air conditioner can be obtained, and the panel temperature is used as the current target panel temperature.

[0092] The control unit 130 is used to control the panel temperature by controlling a temperature control device on the panel so that the panel reaches the target panel temperature. The temperature control device includes a heating device and a cooling device.

[0093] Specifically, the temperature control device is controlled according to the current panel temperature and the target temperature, so that the panel reaches the target panel temperature. The temperature control device includes a heating device and a cooling device, and the panel temperature can be controlled by controlling the heating device and the cooling device. A temperature sensor is also provided on the panel, which can detect the panel temperature. According to the panel temperature detected by the temperature sensor, the heating device is controlled to heat the panel or the cooling device is controlled to cool the panel. By controlling the panel temperature, the natural frequency and sound power of the panel at each frequency point can be controlled to obtain the loudness, sharpness and roughness, thereby improving the sound quality of the air conditioner from the perspective of panel noise reduction.

[0094] Figure 7 FIG. 1 is a structural block diagram of an embodiment of the air conditioner control device provided by the present invention. Figure 7 As shown, the control device 100 further includes: a receiving unit 140 and a display unit 150 .

[0095] The receiving unit 140 is used to receive an activation instruction for activating the augmented reality mode, and activate the augmented reality mode of the air conditioner when the activation instruction is received.

[0096] The display unit 150 is used to display the current sound quality parameters of the air conditioner, the current internal operation status of the air conditioner, and the internal dirtiness of the air conditioner in an augmented reality manner.

[0097] Specifically, by collecting user gesture images, identifying the gesture start command for turning on the augmented reality mode issued by the user through gestures (for example, raising the hand from the bottom to the top), or receiving the voice start command for turning on the augmented reality mode issued by the user through voice, the augmented reality (AR) mode is turned on, and after entering the AR mode, the parameter values ​​of the current sound quality parameters of the air conditioner, the current internal operation of the air conditioner, and the internal dirtiness of the air conditioner are displayed through AR. The internal dirtiness of the air conditioner includes the distribution of bacteria and / or dust inside the air conditioner. For example, the interior of the air conditioner can be photographed by a camera inside the air conditioner, the image can be displayed through a display screen, and the names of the internal components of the air conditioner, the number and / or distribution location of bacteria, and / or the distribution location and / or coverage area of ​​dust can be displayed on the displayed image through AR.

[0098] For existing air-conditioning display screens, through built-in sensors such as accelerometers, gyroscopes, CCDs, biosensors, infrared sensors, etc., gestures or voice control can be used to turn on its AR mode. The screen will display the actual internal operating conditions of the air conditioner through AR, and display internal dirt such as bacteria and dust in a numerical form. It can also display the comfort parameters corresponding to the sound quality.

[0099] Optionally, the control device 100 may also include: a first reminder unit (not shown), which is used to remind the user to use the self-cleaning function before using the air conditioner, and then remind the user to turn on the self-cleaning function every preset time (for example, every month), and remind the user to disassemble and clean the air conditioner when the internal dirtiness threshold of the air conditioner reaches a preset threshold. For example, when the area of ​​the internal area of ​​the air conditioner covered by bacteria and / or dust reaches 30%, the user is reminded to do simple disassembly and cleaning; when the area of ​​the internal area of ​​the air conditioner covered by bacteria and / or dust reaches 60%, the user is reminded that a professional is needed to come to the door for disassembly and cleaning services.

[0100] Optionally, the control device 100 may further include: a second reminder unit (not shown) for reminding the user to turn on the fresh air function or open windows for ventilation when the ambient TVOC concentration and / or carbon dioxide concentration reaches a corresponding preset threshold.
