Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and specifically relates to a control method and device for an air conditioner, an air conditioner, a storage medium and a computer program product. Background Art

[0002] As consumers pay more and more attention to health, air purification function has gradually become a standard feature of air conditioners. Ion generators can give air conditioners functions such as air purification and sterilization. They are usually installed inside the air duct close to the air outlet, and generate ions through corona discharge and other methods. Then, they are sent into the room with the air to purify the room.

[0003] Since the ion concentration decays quickly and has a short lifespan, especially when passing through some narrow spaces, the ion concentration will decrease due to electrostatic shielding, surface adsorption and other reasons, resulting in a greater attenuation, and the purification effect will not meet expectations. Therefore, the ion generator is generally placed at the air outlet of the air conditioner. In an air conditioner with up and down air outlet modes, the position of the air inlet and outlet will also change after the air conditioner switches the air outlet mode. When the ion generator is placed at the downwind outlet, but the air conditioner is upwind, the ions generated by the ion generator need to pass through the air duct, heat exchanger, etc. before they can be sent out from the air outlet. The ion concentration will definitely decay significantly. At this time, if the conventional purification parameters are still followed, such as the same operating time, the expected effect cannot be achieved.

[0044] 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.

[0045] According to an embodiment of the present invention, a control method for an air conditioner is provided, wherein an indoor unit of the air conditioner has a first two-way air outlet and a second two-way air outlet; an ion generator is provided at the first two-way air outlet; the air conditioner has a first air supply mode and a second air supply mode; the first air supply mode is a mode in which the first two-way air outlet is for air outlet and the second two-way air outlet is for air intake, and the second air supply mode is a mode in which the first two-way air outlet is for air intake and the second two-way air outlet is for air outlet, that is, in the second air supply mode, the ion generator is far away from the air outlet.

[0046] The specific structure of the indoor unit is as follows: Figure 3 As shown, the first two-way air outlet 3 is the downwind outlet, and the second two-way air outlet 4 is the upwind outlet. An ion generator (not shown in the figure) is arranged at the first two-way air outlet 3, which is mainly a negative ion, plasma and positive and negative ion plasma generator. When the downwind outlet is the air outlet and the upwind outlet is the air inlet, the ions generated by the ion generator can be directly discharged into the room with the air outlet. By changing the rotation direction of the internal fan 1, the air supply mode of the air conditioner can be switched. When the downwind outlet is the air inlet and the upwind outlet is the air outlet, the ions generated by the ion generator need to pass through the internal fan 1, the evaporator 2 and the air duct before they can be discharged into the room. The path that the ions pass through in the indoor unit is too long, and there is a certain ion attenuation. At this time, if the air conditioner still controls the operating parameters of the ion generator according to the way of downwind outlet outlet and upwind outlet air intake, the purification effect of the air conditioner on the indoor air will be reduced. This scheme can ensure that the air conditioner has a good purification effect on the indoor air when the upwind outlet is out and the downwind outlet is in.

[0047] like Figure 1 The flowchart of an embodiment of the method of the present invention is shown in FIG. The air conditioner control method may include: steps S110 to S130.

[0048] In step S110, the pollutant concentration of the indoor air and the air supply mode of the air conditioner are acquired; the air supply mode includes the first air supply mode and the second air supply mode.

[0049] The air conditioner is equipped with an air quality detection device for detecting the concentration of air pollutants. Specifically, it can detect particulate pollutants such as PM2.5 and PM0.3, gaseous pollutants such as formaldehyde, VOC, odor, and the concentration of harmful microorganisms such as bacteria and viruses.

[0050] In step S120 , the ion generator is controlled to turn on according to the pollutant concentration.

[0051] In some embodiments, in step S120, the specific process of controlling the ion generator to turn on according to the pollutant concentration includes: judging the relationship between the pollutant concentration and a preset first pollutant concentration value; if the pollutant concentration is greater than or equal to the preset first pollutant concentration value, turning on the ion generator; if the pollutant concentration is less than the preset first pollutant concentration value, not turning on the ion generator.

[0052] The preset first pollutant concentration value is used to determine whether the indoor air pollution is serious. For particulate pollutants such as PM2.5 and PM0.3, the preset first pollutant concentration value can be set to 0.035mg / m 3 ; For gaseous pollutants such as formaldehyde, VOC, and odor, the preset first pollutant concentration value can be set to 0.03mg / m 3 ; For the concentration of harmful microorganisms such as bacteria and viruses, the preset first pollutant concentration value can be set to 1000 CFU / m 3 Specifically, when the pollutant concentration is ≥ the preset first pollutant concentration value, the indoor air is considered to be polluted and needs to be purified. At this time, the air conditioner runs the purification mode and turns on the ion generator; when the pollutant concentration is < the preset first pollutant concentration value, the indoor air is considered to be clean and no air purification is required.

[0053] Optional, when the particle pollutant concentration is ≥ 0.035 mg / m 3 , gaseous pollutant concentration ≥ 0.03mg / m 3 , Harmful microorganism concentration ≥ 1000 CFU / m 3 When the air conditioner is in purification mode, the ion generator is turned on.

[0054] At step S130, after the ion generator is turned on, the operating time and discharge voltage of the ion generator are controlled according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner; the operating parameters include the internal fan speed and the ion concentration of the ion generator.

[0055] This solution controls the operating time and discharge voltage of the ion generator according to the air supply mode and operating parameters of the air conditioner, so that the air outlet can have a certain ion concentration when the air conditioner is discharging air from the upper air outlet and taking air in from the lower air outlet, thereby ensuring that the air conditioner has a better purification effect on the indoor air.

[0056] In some embodiments, in step S130, the operation time and discharge voltage of the ion generator are controlled according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner, including: when the air supply mode is the first air supply mode, the discharge voltage of the ion generator is controlled to be a preset first voltage value; the first operation time of the ion generator is determined according to a preset first formula, and the operation time of the ion generator is controlled to be the first operation time. The preset first formula is:

[0057] t1=k1·cx / (c·v);

[0058] Among them, t1 is the first operating time; cx is the pollutant concentration; v is the internal fan speed; c is the ion concentration, c=k2·U, U is the discharge voltage, k1 and k2 are preset parameters.

[0059] In the first air supply mode, since the ion generator is located at the downwind port, the purified ions are directly sent out after being generated, and there is no attenuation problem. Therefore, the purification time is directly calculated according to the pollutant concentration. At this time, the discharge voltage of the ion generator is a preset constant. The operating time t1 of the ion generator is related to the ion concentration c, the internal fan speed v, and the pollutant concentration cx, that is, t1 = f1 (c, v, C), specifically t1 = k1·cx / (c·v). That is, the more serious the pollution, the smaller the ion concentration, and the smaller the internal fan speed, the longer the operating time of the ion generator. Among them, the ion concentration is an inherent property of the ion generator and is related to the discharge voltage, that is, c = f2 (U), specifically c = k2·U.

[0060] In some embodiments, in step S130, the operation time and discharge voltage of the ion generator are controlled according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner, and the second operation time of the ion generator is determined according to a preset second formula when the air supply mode is the second air supply mode, and the operation time of the ion generator is controlled to be the second operation time. The preset second formula is:

[0061] t2=k3·t / β;

[0062] Among them, t2 is the second operating time; t is the preset theoretical operating time; β is the ion attenuation coefficient, β=k4·v, v is the speed of the internal fan; k3 and k4 are preset parameters.

[0063] When the indoor air conditioner needs to be purified, if the air is discharged from the upper air outlet at this time, since the ion generator is located at the lower air outlet, the purified ions need to pass through the air duct, heat exchanger and other components after they are generated before they can be sent out from the upper air outlet to achieve the purification effect. The ions have a certain attenuation, so it is necessary to extend the operating time of the ion generator and increase the discharge voltage of the ion generator to achieve the expected purification effect.

[0064] When extending the operating time of the ion generator, it is necessary to determine the actual operating time in combination with the ion attenuation coefficient. The attenuation coefficient β is less than 1. The more severe the ion attenuation, the smaller the attenuation coefficient β. The attenuation coefficient is related to the wind speed of the internal fan, that is, β = f3 (v), specifically β = k4·v, that is, the higher the wind speed, the more obvious the ion attenuation.

[0065] The preset theoretical operating time t is the operating time of the ion generator preset by the system when the operating time is not extended, and the extended operating time t2>the preset theoretical operating time t.

[0066] In the second formula, since the attenuation coefficient is less than 1, and the higher the wind speed, the smaller the attenuation coefficient, the more serious the ion attenuation, the longer the extended operation time t2. By determining the attenuation coefficient according to the wind speed of the fan and extending the actual operation time in combination with the theoretical operation time, the expected purification effect is ensured, while avoiding the purification time being extended too long and affecting the user experience.

[0067] In some embodiments, in step S130, the operation time and discharge voltage of the ion generator are controlled according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner, and the step further includes: when the air supply mode is the second air supply mode, the actual discharge voltage of the ion generator is determined according to a preset third formula, and the discharge voltage of the ion generator is controlled to be the actual discharge voltage. The preset third formula is:

[0068] U1=k5·U / β;

[0069] Among them, U1 is the actual discharge voltage; U is the preset theoretical discharge voltage; β is the ion attenuation coefficient, β=k4·v, v is the internal fan speed; k4 and k5 are preset parameters.

[0070] In order to ensure a better air purification effect when the air conditioner is running in the second air supply mode, the discharge voltage of the ion generator can also be increased to generate more negative ions or positive ions and improve the purification effect. For example, when extending the running time cannot meet the requirements (the second running time exceeds the maximum purification time acceptable to the user), or in order to achieve the purification effect without adjusting the purification time, the discharge voltage of the ion generator is increased.

[0071] The actual discharge voltage of the ion generator is related to the attenuation coefficient of the ions, U1 = f4 (U, β), specifically U1 = k5·U / β. That is, the greater the wind speed, the greater the actual discharge voltage of the ion generator. By increasing the discharge voltage of the ion generator, the ion concentration can be increased, so that more ions are sent into the room by the air conditioner, and the purification effect is improved.

[0072] In some embodiments, the process of controlling the air supply mode of the air conditioner to switch from the second air supply mode to the first air supply mode during the operation of the ion generator is also included. The process specifically includes: after controlling the operating time of the ion generator to be the preset time of the second operating time, judging the relationship between the pollutant concentration and the preset second pollutant concentration value; if the pollutant concentration is greater than or equal to the preset second pollutant concentration value, controlling the air supply mode to be the first air supply mode; if the pollutant concentration is less than the preset second pollutant concentration value, controlling the air conditioner to maintain the current operating state.

[0073] In some embodiments, the process of controlling the air supply mode of the air conditioner to switch from the second air supply mode to the first air supply mode during the operation of the ion generator also includes: after controlling the discharge voltage of the ion generator to be the preset time of the actual discharge voltage, judging the relationship between the pollutant concentration and the preset second pollutant concentration value; if the pollutant concentration is greater than or equal to the preset second pollutant concentration value, controlling the air supply mode to be the first air supply mode; if the pollutant concentration is less than the preset second pollutant concentration value, controlling the air conditioner to maintain the current operating state.

[0074] After the air conditioner adjusts the running time and discharge voltage of the ion generator in the second air supply mode, if the expected purification effect cannot be achieved, the air supply mode of the air conditioner is switched without affecting the current use effect of the user, so that the air conditioner is discharged from the bottom and the air is inletted from the top, thereby avoiding the attenuation of ions in the indoor unit and improving the purification effect. After the air conditioner is switched to the bottom outlet and the top inlet, the running time and discharge voltage of the ion generator are readjusted. Specifically, during the continuous operation of the ion generator, the pollutant concentration will continue to decrease. If the rate of decrease of the pollutant concentration is small, the pollutant concentration ≥ the preset second pollutant concentration after the preset time, and it cannot be guaranteed that the indoor pollutant concentration will be reduced to the target value after the ion generator ends. At this time, it can be switched to the first air supply mode without affecting the user's use; if the rate of decrease of the pollutant concentration is high, the pollutant concentration < the preset second pollutant concentration after the preset time, so that the indoor pollutant concentration can be reduced to the target value when the ion generator ends. At this time, there is no need to switch the air supply mode, and the air conditioner maintains the current state.

[0075] Figure 4 FIG. 1 is a flow chart of the ion purification control method of the air conditioner of the present invention, as shown in FIG. Figure 4 As shown, the method includes:

[0076] Step 1: After the air conditioner is turned on, indoor environmental parameters are detected in real time or at regular intervals, including indoor pollutant concentrations.

[0077] Step 2: Determine whether the room needs to be purified based on the pollutant concentration. If the room does not need to be purified, the air conditioner is controlled to continue to operate according to the current parameters; if the room needs to be purified, step 3 is executed.

[0078] Step 3: adjust the purification operation parameters of the ion generator according to the air conditioner operation parameters, the air conditioner operation parameters include the internal fan speed, air supply mode, and pollutant concentration, and the purification operation parameters of the ion generator include the operation time and discharge voltage.

[0079] By adopting the technical solution of this embodiment, when the air conditioner is running, the ion generator is controlled to start according to the indoor pollutant concentration, and then the running time and discharge voltage of the ion generator are controlled according to the air supply mode of the air conditioner, the pollutant concentration, and the operating parameters of the air conditioner. Thus, by controlling the running time and discharge voltage of the ion generator according to the air supply mode of the air conditioner and the operating parameters of the air conditioner, the air conditioner can ensure a good purification effect even when the ion generator is far away from the air outlet, thereby improving the user experience.

[0080] According to an embodiment of the present invention, a control device for an air conditioner corresponding to the control method for an air conditioner is also provided. The indoor unit of the air conditioner has a first two-way air outlet and a second two-way air outlet; an ion generator is arranged at the first two-way air outlet; the air conditioner has a first air supply mode and a second air supply mode; the first air supply mode is a mode in which the first two-way air outlet is outgoing and the second two-way air outlet is incoming; the second air supply mode is a mode in which the first two-way air outlet is incoming and the second two-way air outlet is outgoing, that is, in the second air supply mode, the ion generator is far away from the air outlet.

[0081] The specific structure of the indoor unit is as follows: Figure 3As shown, the first two-way air outlet 3 is the downwind outlet, and the second two-way air outlet 4 is the upwind outlet. An ion generator (not shown in the figure) is arranged at the first two-way air outlet 3, which is mainly a negative ion, plasma and positive and negative ion plasma generator. When the downwind outlet is the air outlet and the upwind outlet is the air inlet, the ions generated by the ion generator can be directly discharged into the room with the air outlet. By changing the rotation direction of the internal fan 1, the air supply mode of the air conditioner can be switched. When the downwind outlet is the air inlet and the upwind outlet is the air outlet, the ions generated by the ion generator need to pass through the internal fan 1, the evaporator 2 and the air duct before they can be discharged into the room. The path that the ions pass through in the indoor unit is too long, and there is a certain ion attenuation. At this time, if the air conditioner still controls the operating parameters of the ion generator according to the way of downwind outlet outlet and upwind outlet air intake, the purification effect of the air conditioner on the indoor air will be reduced. This scheme can ensure that the air conditioner has a good purification effect on the indoor air when the upwind outlet is out and the downwind outlet is in.

[0082] See also Figure 2 The schematic diagram of the structure of an embodiment of the device of the present invention is shown. The control device of the air conditioner may include: an acquisition unit 102 and a control unit 104.

[0083] The acquisition unit 102 is configured to acquire the pollutant concentration of the indoor air and the air supply mode of the air conditioner; the air supply mode includes the first air supply mode and the second air supply mode. The specific functions and processing of the acquisition unit 102 refer to step S110.

[0084] The air conditioner is equipped with an air quality detection device for detecting the concentration of air pollutants. Specifically, it can detect particulate pollutants such as PM2.5 and PM0.3, gaseous pollutants such as formaldehyde, VOC, odor, and the concentration of harmful microorganisms such as bacteria and viruses.

[0085] The control unit 104 is configured to control the ion generator to start according to the pollutant concentration. The specific functions and processing of the control unit 104 refer to step S120.

[0086] In some embodiments, the control unit 104 controls the specific process of turning on the ion generator according to the pollutant concentration, including: judging the size relationship between the pollutant concentration and a preset first pollutant concentration value; if the pollutant concentration is greater than or equal to the preset first pollutant concentration value, turning on the ion generator; if the pollutant concentration is less than the preset first pollutant concentration value, not turning on the ion generator.

[0087] The preset first pollutant concentration value is used to determine whether the indoor air pollution is serious. For particulate pollutants such as PM2.5 and PM0.3, the preset first pollutant concentration value can be set to 0.035mg / m 3; For gaseous pollutants such as formaldehyde, VOC, and odor, the preset first pollutant concentration value can be set to 0.03mg / m 3 ; For the concentration of harmful microorganisms such as bacteria and viruses, the preset first pollutant concentration value can be set to 1000 CFU / m 3 Specifically, when the pollutant concentration is ≥ the preset first pollutant concentration value, the indoor air is considered to be polluted and needs to be purified. At this time, the air conditioner runs the purification mode and turns on the ion generator; when the pollutant concentration is < the preset first pollutant concentration value, the indoor air is considered to be clean and no air purification is required.

[0088] Optional, when the particle pollutant concentration is ≥ 0.035 mg / m 3 , gaseous pollutant concentration ≥ 0.03mg / m 3 , Harmful microorganism concentration ≥ 1000 CFU / m 3 When the air conditioner is in purification mode, the ion generator is turned on.

[0089] The control unit 104 is further configured to control the operation time and discharge voltage of the ion generator according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner after the ion generator is turned on; the operating parameters include the internal fan speed and the ion concentration of the ion generator. The specific functions and processing of the control unit 104 refer to step S130.

[0090] This solution controls the operating time and discharge voltage of the ion generator according to the air supply mode and operating parameters of the air conditioner, so that the air outlet can have a certain ion concentration when the air conditioner is discharging air from the upper air outlet and taking air in from the lower air outlet, thereby ensuring that the air conditioner has a better purification effect on the indoor air.

[0091] In some embodiments, the control unit 104 controls the operating time and discharge voltage of the ion generator according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner, including: when the air supply mode is the first air supply mode, controlling the discharge voltage of the ion generator to be a preset first voltage value; determining the first operating time of the ion generator according to a preset first formula, and controlling the operating time of the ion generator to be the first operating time. The preset first formula is:

[0092] t1=k1·cx / (c·v);

[0093] Among them, t1 is the first operating time; cx is the pollutant concentration; v is the internal fan speed; c is the ion concentration, c=k2·U, U is the discharge voltage, k1 and k2 are preset parameters.

[0094] In the first air supply mode, since the ion generator is located at the downwind port, the purified ions are directly sent out after being generated, and there is no attenuation problem. Therefore, the purification time is directly calculated according to the pollutant concentration. At this time, the discharge voltage of the ion generator is a preset constant. The operating time t1 of the ion generator is related to the ion concentration c, the internal fan speed v, and the pollutant concentration cx, that is, t1 = f1 (c, v, C), specifically t1 = k1·cx / (c·v). That is, the more serious the pollution, the smaller the ion concentration, and the smaller the internal fan speed, the longer the operating time of the ion generator. Among them, the ion concentration is an inherent property of the ion generator and is related to the discharge voltage, that is, c = f2 (U), specifically c = k2·U.

[0095] In some embodiments, the control unit 104 controls the operating time and discharge voltage of the ion generator according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner, and further includes: when the air supply mode is the second air supply mode, determining the second operating time of the ion generator according to a preset second formula, and controlling the operating time of the ion generator to be the second operating time. The preset second formula is:

[0096] t2=k3·t / β;

[0097] Among them, t2 is the second operating time; t is the preset theoretical operating time; β is the ion attenuation coefficient, β=k4·v, v is the speed of the internal fan; k3 and k4 are preset parameters.

[0098] When the indoor air conditioner needs to be purified, if the air is discharged from the upper air outlet at this time, since the ion generator is located at the lower air outlet, the purified ions need to pass through the air duct, heat exchanger and other components after they are generated before they can be sent out from the upper air outlet to achieve the purification effect. The ions have a certain attenuation, so it is necessary to extend the operating time of the ion generator and increase the discharge voltage of the ion generator to achieve the expected purification effect.

[0099] When extending the operating time of the ion generator, it is necessary to determine the actual operating time in combination with the ion attenuation coefficient. The attenuation coefficient β is less than 1. The more severe the ion attenuation, the smaller the attenuation coefficient β. The attenuation coefficient is related to the wind speed of the internal fan, that is, β = f3 (v), specifically β = k4·v, that is, the higher the wind speed, the more obvious the ion attenuation.

[0100] The preset theoretical operating time t is the operating time of the ion generator preset by the system when the operating time is not extended, and the extended operating time t2>the preset theoretical operating time t.

[0101] In the second formula, since the attenuation coefficient is less than 1, and the higher the wind speed, the smaller the attenuation coefficient, the more serious the ion attenuation, the longer the extended operation time t2. By determining the attenuation coefficient according to the wind speed of the fan and extending the actual operation time in combination with the theoretical operation time, the expected purification effect is ensured, while avoiding the purification time being extended too long and affecting the user experience.

[0102] In some embodiments, the control unit 104 controls the operating time and discharge voltage of the ion generator according to the air supply mode, the pollutant concentration, and the operating parameters of the air conditioner, and further includes: when the air supply mode is the second air supply mode, determining the actual discharge voltage of the ion generator according to a preset third formula, and controlling the discharge voltage of the ion generator to be the actual discharge voltage. The preset third formula is:

[0103] U1=k5·U / β;

[0104] Among them, U1 is the actual discharge voltage; U is the preset theoretical discharge voltage; β is the ion attenuation coefficient, β=k4·v, v is the internal fan speed; k4 and k5 are preset parameters.

[0105] In order to ensure a better air purification effect when the air conditioner is running in the second air supply mode, the discharge voltage of the ion generator can also be increased to generate more negative ions or positive ions and improve the purification effect. For example, when extending the running time cannot meet the requirements (the second running time exceeds the maximum purification time acceptable to the user), or in order to achieve the purification effect without adjusting the purification time, the discharge voltage of the ion generator is increased.

[0106] The actual discharge voltage of the ion generator is related to the attenuation coefficient of the ions, U1 = f4 (U, β), specifically U1 = k5·U / β. That is, the greater the wind speed, the greater the actual discharge voltage of the ion generator. By increasing the discharge voltage of the ion generator, the ion concentration can be increased, so that more ions are sent into the room by the air conditioner, and the purification effect is improved.

[0107] In some embodiments, the control unit 104 is also configured to: after controlling the operating time of the ion generator to be a preset time of the second operating time, determine the relationship between the pollutant concentration and the preset second pollutant concentration value; if the pollutant concentration is greater than or equal to the preset second pollutant concentration value, control the air supply mode to be the first air supply mode; if the pollutant concentration is less than the preset second pollutant concentration value, control the air conditioner to maintain the current operating state.

[0108] In some embodiments, the control unit 104 is also configured to: after controlling the discharge voltage of the ion generator to be the actual discharge voltage for a preset time, determine the relationship between the pollutant concentration and a preset second pollutant concentration value; if the pollutant concentration is greater than or equal to the preset second pollutant concentration value, control the air supply mode to be the first air supply mode; if the pollutant concentration is less than the preset second pollutant concentration value, control the air conditioner to maintain the current operating state.

[0109] After the air conditioner adjusts the running time and discharge voltage of the ion generator in the second air supply mode, if the expected purification effect cannot be achieved, the air supply mode of the air conditioner is switched without affecting the current use effect of the user, so that the air conditioner is discharged from the bottom and the air is inletted from the top, thereby avoiding the attenuation of ions in the indoor unit and improving the purification effect. After the air conditioner is switched to the bottom outlet and the top inlet, the running time and discharge voltage of the ion generator are readjusted. Specifically, during the continuous operation of the ion generator, the pollutant concentration will continue to decrease. If the rate of decrease of the pollutant concentration is small, the pollutant concentration ≥ the preset second pollutant concentration after the preset time, and it cannot be guaranteed that the indoor pollutant concentration will be reduced to the target value after the ion generator ends. At this time, it can be switched to the first air supply mode without affecting the user's use; if the rate of decrease of the pollutant concentration is high, the pollutant concentration < the preset second pollutant concentration after the preset time, so that the indoor pollutant concentration can be reduced to the target value when the ion generator ends. At this time, there is no need to switch the air supply mode, and the air conditioner maintains the current state.

[0112] Step 2: Determine whether the room needs to be purified based on the pollutant concentration. If the room does not need to be purified, the air conditioner is controlled to continue to operate according to the current parameters; if the room needs to be purified, step 3 is executed.

[0113] Step 3: adjust the purification operation parameters of the ion generator according to the air conditioner operation parameters, the air conditioner operation parameters include the internal fan speed, air supply mode, and pollutant concentration, and the purification operation parameters of the ion generator include the operation time and discharge voltage.
