[0055] The temperature sensor A, polluted gas sensor B, ozone sensor C located at the main return air outlet 1 and the humidity sensor D and oxygen sensor E located at the outlet end of the air-conditioning unit 2 are connected to the integrated processor 12 of the main controller 11 through signal lines to collect and process the collected environmental signals, and guide the actuator 13 to make corresponding execution instructions to each component of the air purification subsystem 10.

[0058] Reference below Figure 4 A method for controlling an air conditioner according to an embodiment of the present invention is described.

[0059] like Figure 4 As shown, the control method of the air conditioner includes the following steps:

[0060] Step S1: Obtain indoor polluted gas parameters and air conditioning parameters.

[0061] Specifically, in the process of controlling the air conditioner, the information of the indoor polluted gas can be sensed and detected by setting up different gas sensors, including but not limited to real-time detection and acquisition of polluted gas parameters in the indoor air through polluted gas sensors based on electrochemistry, photoionization, metal oxide semiconductor and other technologies, wherein the polluted gases include but are not limited to VOC concentration, odor concentration, microbial bacteria concentration, etc.; further, air conditioning parameters can also be acquired through different sensors, including but not limited to acquiring the indoor temperature through a temperature sensor, acquiring the indoor humidity through a humidity sensor, acquiring the indoor oxygen concentration through an oxygen sensor, acquiring the information of ozone in the indoor air through real-time detection through an ozone sensor, etc.

[0062] Step S2: Determine the purification mode of the air conditioner according to the polluted gas.

[0063] Specifically, after obtaining the information of indoor polluted gases, the quality of the current indoor air can be judged according to the information of polluted gases, thereby determining the purification mode of the current air conditioner. For example, the purification mode of the current air conditioner can be determined according to the concentration of polluted gases. When a high concentration of polluted gases is detected, the deep purification mode of the air conditioner can be activated; if a high concentration of polluted gases is detected, the low-temperature plasma purification mode or photocatalytic purification mode of the air conditioner can be activated. It can be understood that determining the purification mode of the air conditioner according to the polluted gases can ensure that the air conditioner maintains the best purification effect during operation and maintains the overall comfort of the indoor environment.

[0064] Step S3: In the purification mode, the operating state of the air purification subsystem is controlled according to the air conditioning parameters.

[0065] Specifically, after determining the purification mode of the air conditioner, the various settings of the air purification subsystem can be dynamically adjusted according to the air conditioning parameters (humidity, oxygen concentration, etc. of the current indoor environment), so as to achieve precise control of the operating status of the air purification subsystem. That is, in different purification modes, the operating status of the air purification subsystem can be intelligently controlled according to the actual environmental conditions, so as to quickly and efficiently reduce the concentration of indoor pollutants, kill bacteria and microorganisms, and improve indoor air quality while ensuring user safety. At the same time, it can reduce unnecessary energy consumption and improve energy utilization efficiency.

[0066] Therefore, the above-mentioned air conditioning control method can obtain indoor polluted gas parameters and air conditioning parameters through real-time monitoring, and can determine the current optimal purification mode of the air conditioner according to the polluted gas, and in the determined purification mode, can accurately control the operating state of the air purification subsystem according to the air conditioning parameters, thereby quickly and efficiently reducing the concentration of indoor polluted gases, killing bacteria and microorganisms, and improving indoor air quality while ensuring user safety. At the same time, it can reduce unnecessary energy consumption and improve energy utilization efficiency.

[0067] In one embodiment of the present invention, the air purification subsystem includes a low-temperature plasma purification subsystem and a photocatalytic purification subsystem, and the air conditioning parameters include an oxygen concentration value. In the purification mode, the operating state of the air purification subsystem is controlled according to the air conditioning parameters, including: when the purification mode is a deep purification mode, the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem and the photocatalytic purification unit in the photocatalytic purification subsystem are controlled according to the oxygen concentration value, and / or the start state of the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem and the photocatalytic fresh air unit in the photocatalytic purification subsystem.

[0068] Specifically, the air purification subsystem includes a low-temperature plasma purification subsystem and a photocatalytic purification subsystem. In the purification mode, when the operating state of the air purification subsystem is controlled according to the air conditioning parameters, if the purification mode is the deep purification mode, it means that the current indoor polluted gas concentration is high. At this time, the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem and the photocatalytic purification unit in the photocatalytic purification subsystem can be controlled to increase or decrease according to the oxygen concentration value, and / or the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem and the photocatalytic fresh air unit in the photocatalytic purification subsystem can be controlled to be turned on or off.

[0069] In one embodiment of the present invention, the output power of a low-temperature plasma purification unit in a low-temperature plasma purification subsystem and a photocatalytic purification unit in a photocatalytic purification subsystem are controlled according to the oxygen concentration value, including: when the oxygen concentration value is greater than or equal to a preset oxygen concentration threshold, adjusting the output power of the low-temperature plasma purification unit to a first preset power and adjusting the output power of the photocatalytic purification unit to a second preset power; when the oxygen concentration value is less than the preset oxygen concentration threshold, adjusting the output power of the low-temperature plasma purification unit to a third preset power and adjusting the output power of the photocatalytic purification unit to a fourth preset power, wherein the first preset power is greater than the third preset power, and the second preset power is greater than the fourth preset power.

[0070] Specifically, when the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem and the photocatalytic purification unit in the photocatalytic purification subsystem is controlled according to the oxygen concentration value, if the oxygen concentration value detected by the oxygen sensor is greater than or equal to the preset oxygen concentration threshold, it means that there is sufficient oxygen in the room for both the low-temperature plasma purification unit and the photocatalytic purification unit to perform efficient purification work, and the indoor oxygen will not be low due to oxygen consumption, which will bring a poor experience to the user. At this time, the output power of the low-temperature plasma purification unit can be adjusted to the first preset power and the output power of the photocatalytic purification unit can be adjusted to the second preset power to ensure that the plasma is fully activated and the photocatalytic reaction operates efficiently, effectively decomposing polluted gases and killing microorganisms, while ensuring The indoor oxygen concentration will not be too low due to increasing power; if the oxygen concentration value is less than the preset oxygen concentration threshold, it means that there is not enough oxygen in the room for the low-temperature plasma purification unit and the photocatalytic purification unit to perform efficient purification work. The low-temperature plasma purification unit and the photocatalytic purification unit maintain current power operation, which may increase energy consumption while affecting the purification effect of the low-temperature plasma purification unit and the photocatalytic purification unit. It may also cause insufficient indoor oxygen, giving users a poor experience. At this time, the output power of the low-temperature plasma purification unit can be adjusted to the third preset power and the output power of the photocatalytic purification unit can be adjusted to the fourth preset power, so that the low-temperature plasma purification unit and the photocatalytic purification unit can still maintain a certain purification efficiency while reducing energy consumption.

[0071] In a specific embodiment, the preset oxygen concentration threshold, the first preset power, the second preset power, the third preset power, and the fourth preset power can be set according to actual conditions, wherein the first preset power is greater than the third preset power, and the second preset power is greater than the fourth preset power.

[0072] In one embodiment of the present invention, the opening states of the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem and the photocatalytic fresh air unit in the photocatalytic purification subsystem are controlled according to the oxygen concentration value, including: when the oxygen concentration value is less than a preset oxygen concentration threshold, the low-temperature plasma fresh air unit and the photocatalytic fresh air unit are turned on until the oxygen concentration value reaches the preset oxygen concentration threshold.

[0073] Specifically, when the opening status of the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem and the photocatalytic fresh air unit in the photocatalytic purification subsystem is controlled according to the oxygen concentration value, if the oxygen concentration value detected by the oxygen sensor is less than the preset oxygen concentration threshold, it means that the current indoor air quality is poor and more fresh air needs to be introduced to increase the oxygen concentration. At this time, the low-temperature plasma fresh air unit and the photocatalytic fresh air unit can be controlled to be turned on at the same time to introduce fresh air from the outside to increase the oxygen content in the room. At the same time, the current indoor oxygen concentration can be monitored in real time until the oxygen concentration value returns to the preset oxygen concentration threshold.

[0074] In one embodiment of the present invention, the output power of a low-temperature plasma purification unit in a low-temperature plasma purification subsystem and a photocatalytic purification unit in a photocatalytic purification subsystem and the start-up state of a low-temperature plasma fresh air unit in a low-temperature plasma purification subsystem and a photocatalytic fresh air unit in a photocatalytic purification subsystem are controlled according to the oxygen concentration value, including: when the oxygen concentration value is less than a preset oxygen concentration threshold, adjusting the low-temperature plasma purification unit to a third preset power and adjusting the output power of the photocatalytic purification unit to a fourth preset power, and starting the low-temperature plasma fresh air unit and the photocatalytic fresh air unit until the preset oxygen concentration threshold is reached.

[0075] Specifically, when the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem and the photocatalytic purification unit in the photocatalytic purification subsystem and the opening state of the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem and the photocatalytic fresh air unit in the photocatalytic purification subsystem are controlled according to the oxygen concentration value, if the oxygen concentration value detected by the oxygen sensor is less than the preset oxygen concentration threshold value, it means that there is not enough oxygen in the room for the low-temperature plasma purification unit and the photocatalytic purification unit to perform efficient purification work. If the low-temperature plasma purification unit and the photocatalytic purification unit maintain the current power operation, it may increase energy consumption while affecting the low-temperature plasma purification unit and the photocatalytic purification unit. At this time, the output power of the low-temperature plasma purification unit can be adjusted to the third preset power and the output power of the photocatalytic purification unit can be adjusted to the fourth preset power, so that the low-temperature plasma purification unit and the photocatalytic purification unit can still maintain a certain purification efficiency while reducing energy consumption. Furthermore, while adjusting the output power of the low-temperature plasma purification unit and the photocatalytic purification unit to the fourth preset power, the low-temperature plasma fresh air unit and the photocatalytic fresh air unit can be turned on at the same time to introduce fresh air from outdoors into the room to increase the indoor oxygen concentration, thereby achieving the purpose of effectively controlling the oxygen concentration and continuing to provide air purification.

[0076] In one embodiment of the present invention, the air conditioning parameters also include an ozone concentration value. In the process of controlling the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem and the photocatalytic purification unit in the photocatalytic purification subsystem according to the oxygen concentration value, it also includes: when the time when the ozone concentration value exceeds the ozone concentration threshold reaches a first preset time threshold, shutting down one of the low-temperature plasma purification unit and the photocatalytic purification unit, until the time when the ozone concentration value exceeds the ozone concentration threshold reaches a second preset time threshold, shutting down one of the low-temperature plasma purification unit and the photocatalytic purification unit that is not shut down, wherein the second preset time is greater than the first preset time.

[0077] Specifically, since ozone can be generated as a by-product during the low-temperature plasma purification and photocatalytic reaction purification processes, in the process of controlling the opening state of the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem and the photocatalytic fresh air unit in the photocatalytic purification subsystem according to the oxygen concentration value, the indoor ozone concentration value can also be obtained by real-time monitoring through the ozone sensor. If the ozone concentration value exceeds the preset ozone concentration threshold and the duration reaches the first preset time threshold, it means that the current indoor ozone concentration continues to increase, which will threaten the safety of the user. At this time, one of the low-temperature plasma purification unit and the photocatalytic purification unit can be controlled to be turned off to prevent the ozone concentration from continuing to increase, while continuing to introduce outdoor fresh air into the room to increase the indoor oxygen concentration; further, the indoor ozone concentration can be continuously monitored until the ozone concentration value exceeds the ozone concentration threshold for a time that reaches the second preset time threshold, indicating that the current indoor ozone has threatened the safety of the user. At this time, one of the low-temperature plasma purification unit and the photocatalytic purification unit that is not turned off can be turned off to prevent the ozone concentration from continuing to increase, thereby protecting the health of the user and providing the user with a safe indoor environment.

[0078] In one embodiment of the present invention, the air purification subsystem includes a low-temperature plasma purification subsystem, and the air conditioning parameters include an oxygen concentration value.

[0079] Specifically, the air purification subsystem includes a low-temperature plasma purification subsystem, and the air conditioning parameters include an oxygen concentration value. In the low-temperature plasma purification subsystem, low-temperature plasma is generated by high-voltage discharge and other methods, and contains a large number of active particles such as electrons, ions, and free radicals, which can react chemically with polluted gases in the air and decompose them into harmless substances, such as carbon dioxide and water vapor. In purification mode, if the current purification mode of the air conditioner is the low-temperature plasma purification mode, the output power of the low-temperature plasma purification unit can be controlled to increase or decrease according to the oxygen concentration value, or the low-temperature plasma fresh air unit can be controlled to be in an on or off state, or the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem can be controlled to be in an on or off state while the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem is increased or decreased.

[0081] Specifically, when the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem is controlled according to the oxygen concentration value, if the oxygen concentration value detected by the oxygen sensor is greater than or equal to the preset oxygen concentration threshold, it means that there is sufficient oxygen in the room for the low-temperature plasma purification unit to perform efficient purification work, and the indoor oxygen will not be low due to oxygen consumption, which will bring a poor experience to the user. At this time, the output power of the low-temperature plasma purification unit can be adjusted to the first preset power to ensure that the plasma is fully activated, effectively decomposes polluted gases, kills microorganisms, and accelerates the conversion process of harmful gases, while ensuring that the indoor oxygen concentration is not too low due to increased power; if the oxygen concentration value is less than the preset oxygen concentration threshold, it means that there is not enough oxygen in the room for the low-temperature plasma purification unit to perform efficient purification work. The low-temperature plasma purification unit maintains the current power operation, which may increase energy consumption while affecting the purification effect of the low-temperature plasma purification unit. It may also cause insufficient indoor oxygen, which brings a poor experience to the user. At this time, the output power of the low-temperature plasma purification unit can be adjusted to the third preset power, so that the low-temperature plasma purification unit can still maintain a certain purification efficiency while reducing energy consumption.

[0084] Specifically, when the opening state of the low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem is controlled according to the oxygen concentration value, if the oxygen concentration value detected by the oxygen sensor is less than the preset oxygen concentration threshold, it means that the current indoor air quality is poor and more fresh air needs to be introduced to increase the oxygen concentration. At this time, the low-temperature plasma fresh air unit can be controlled to be turned on to introduce fresh air from the outside to increase the indoor oxygen content. At the same time, the current indoor oxygen concentration can be monitored in real time until the oxygen concentration value returns to the preset oxygen concentration threshold.

[0085] In one embodiment of the present invention, the output power of a low-temperature plasma purification unit in a low-temperature plasma purification subsystem and the start-up state of a low-temperature plasma fresh air unit in the low-temperature plasma purification subsystem are controlled according to the oxygen concentration value, including: when the oxygen concentration value is less than a preset oxygen concentration threshold, adjusting the output power of the low-temperature plasma purification unit to a third preset power and starting the low-temperature plasma fresh air unit until the oxygen concentration value reaches the preset oxygen concentration threshold.

The low-temperature plasma purification unit maintains the current power operation, which may increase energy consumption while affecting the purification effect of the low-temperature plasma purification unit. It may also cause insufficient indoor oxygen, giving users a poor experience. At this time, the output power of the low-temperature plasma purification unit can be adjusted to the third preset power, so that the low-temperature plasma purification unit can still maintain a certain purification efficiency while reducing energy consumption. Furthermore, while adjusting the output power of the low-temperature plasma purification unit to the third preset power, the low-temperature plasma fresh air unit can be turned on to introduce fresh air from the outside into the room to increase the indoor oxygen concentration until the oxygen concentration value reaches the preset oxygen concentration threshold, thereby achieving the purpose of effectively controlling the oxygen concentration and continuing to provide air purification.

[0087] In one embodiment of the present invention, the air conditioning parameters also include an ozone concentration value. In the process of controlling the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem according to the oxygen concentration value, it also includes: when the ozone concentration value exceeds the preset ozone concentration threshold and reaches a first preset time threshold, shutting down the low-temperature plasma purification unit.

[0088] Specifically, since ozone can be produced as a by-product during the low-temperature plasma purification process, in the process of controlling the output power of the low-temperature plasma purification unit in the low-temperature plasma purification subsystem according to the oxygen concentration value, the indoor ozone concentration value can also be monitored in real time by the ozone sensor. If the ozone concentration value exceeds the preset ozone concentration threshold and the duration reaches the first preset time threshold, it means that the current indoor ozone concentration has posed a threat to the user's health. At this time, the low-temperature plasma purification unit can be controlled to shut down to prevent the ozone concentration from continuing to increase, thereby protecting the user's health and providing the user with a safe indoor environment.

[0089] In a specific embodiment, the preset ozone concentration threshold and the first preset time threshold can be set according to actual conditions.

[0090] In one embodiment of the present invention, the air purification subsystem includes a photocatalytic purification subsystem, and the air conditioning parameters include an oxygen concentration value. In the purification mode, the operating state of the air purification subsystem is controlled according to the air conditioning parameters, including: when the purification mode is a photocatalytic purification mode, the output power of the photocatalytic purification unit in the photocatalytic purification subsystem and / or the start state of the photocatalytic fresh air unit in the photocatalytic purification subsystem is controlled according to the oxygen concentration value.

[0091] Specifically, the photocatalytic purification subsystem can activate and catalyze the photocatalytic material under illumination with the help of ultraviolet rays (wavelength below 365nm), generate photogenerated electrons and holes, form photogenerated electron-hole pairs, and react with water molecules and oxygen in the air to generate free radicals with strong oxidizing properties, thereby decomposing pollutants in the air, such as organic compounds such as formaldehyde and benzene, and microorganisms such as bacteria and viruses.

[0092] In one embodiment of the present invention, the output power of the photocatalytic purification unit in the photocatalytic purification subsystem is controlled according to the oxygen concentration value, including: when the oxygen concentration value is greater than or equal to the preset oxygen concentration threshold, adjusting the output power of the photocatalytic purification unit to a second preset power; when the oxygen concentration value is less than the preset oxygen concentration threshold, adjusting the output power of the photocatalytic purification unit to a fourth preset power, wherein the second preset power is greater than the fourth preset power.

[0093] Specifically, when the output power of the photocatalytic purification unit in the photocatalytic purification subsystem is controlled according to the oxygen concentration value, if the oxygen concentration value detected by the oxygen sensor is greater than or equal to the preset oxygen concentration threshold, it means that there is sufficient oxygen in the room for the photocatalytic purification unit to perform an efficient photocatalytic reaction for purification, and the indoor oxygen will not be low due to oxygen consumption, which will bring a poor experience to the user. At this time, the output power of the photocatalytic purification unit can be adjusted to the second preset power to ensure that the photocatalyst can be effectively excited to generate more free radicals, thereby accelerating the decomposition of harmful substances and improving the purification efficiency, while ensuring that the indoor oxygen concentration will not be too low due to the increase in power; if the oxygen concentration value is less than the preset oxygen concentration threshold, it means that there is not enough oxygen in the room for the photocatalytic purification unit to perform an efficient photocatalytic reaction for purification. The photocatalytic purification unit maintains the current power operation, which may increase energy consumption while affecting the purification effect of the photocatalytic purification unit for the photocatalytic reaction, and may also cause insufficient indoor oxygen, which will bring a poor experience to the user. At this time, the output power of the photocatalytic purification unit can be adjusted to the fourth preset power, so that the photocatalytic purification unit can still maintain a certain purification efficiency for the photocatalytic reaction while reducing energy consumption.

[0094] In one embodiment of the present invention, the opening state of the photocatalytic fresh air unit in the photocatalytic purification subsystem is controlled according to the oxygen concentration value, including: when the oxygen concentration value is less than a preset oxygen concentration threshold, turning on the photocatalytic fresh air unit until the preset oxygen concentration threshold is reached.

[0095] Specifically, when the opening state of the photocatalytic fresh air unit in the photocatalytic purification subsystem is controlled according to the oxygen concentration value, if the oxygen concentration value detected by the oxygen sensor is less than the preset oxygen concentration threshold, it means that the current indoor air quality is poor and more fresh air needs to be introduced to increase the oxygen concentration. At this time, the photocatalytic fresh air unit can be controlled to be turned on to introduce fresh air from the outside to increase the indoor oxygen content. At the same time, the current indoor oxygen concentration can be monitored in real time until the oxygen concentration value returns to the preset oxygen concentration threshold.

[0096] In one embodiment of the present invention, the output power of the photocatalytic purification unit in the photocatalytic purification subsystem and the start-up state of the photocatalytic fresh air unit in the photocatalytic purification subsystem are controlled according to the oxygen concentration value, including: when the oxygen concentration value is less than the preset oxygen concentration threshold, the output power of the photocatalytic purification unit is adjusted to a fourth preset power and the photocatalytic fresh air unit is turned on.

The photocatalytic purification unit may maintain the current power operation while increasing energy consumption and affecting the purification effect of the photocatalytic purification unit. It may also cause insufficient indoor oxygen, giving users a poor experience. At this time, the output power of the photocatalytic purification unit can be adjusted to the second preset power so that the photocatalytic reaction performed by the photocatalytic purification unit can still maintain a certain purification efficiency while reducing energy consumption. Furthermore, while adjusting the output power of the photocatalytic purification unit to the fourth preset power, the photocatalytic fresh air unit can be turned on to introduce fresh air from outside into the room to increase the indoor oxygen concentration, thereby achieving the purpose of effectively controlling the oxygen concentration and continuing to provide air purification.

[0098] In one embodiment of the present invention, the air conditioning parameters also include an ozone concentration value. In the process of controlling the output power of the photocatalytic purification unit in the photocatalytic purification subsystem according to the oxygen concentration value, it also includes: when the ozone concentration value exceeds the ozone concentration threshold and reaches a first preset time threshold, shutting down the photocatalytic purification unit.

[0099] Specifically, since ozone can be produced as a by-product during the photocatalytic purification process, in the process of controlling the output power of the photocatalytic purification unit in the photocatalytic purification subsystem according to the oxygen concentration value, the indoor ozone concentration value can also be monitored in real time by the ozone sensor. If the ozone concentration value exceeds the preset ozone concentration threshold and the duration reaches the first preset time threshold, it means that the current indoor ozone concentration has posed a threat to the user's health. At this time, the photocatalytic purification unit can be controlled to shut down to prevent the ozone concentration from continuing to increase, thereby protecting the user's health and providing the user with a safe indoor environment.

[0100] In one embodiment of the present invention, the air purification subsystem also includes a water vapor generator unit, and the air conditioning parameters also include a humidity value. In the purification mode, the process of controlling the operating state of the air purification subsystem according to the air conditioning parameters also includes: when the humidity value is greater than or equal to a preset humidity threshold, turning off the water vapor generator unit; when the humidity value is less than the preset humidity threshold, turning on the water vapor generator unit.

[0101] Specifically, the air purification subsystem also includes a water vapor generator unit, which can generate and release water vapor into the indoor air to increase the indoor humidity. In the purification mode, in the process of controlling the operating state of the air purification subsystem according to the air conditioning parameters, the indoor humidity value can be obtained by real-time monitoring through the humidity sensor. If the humidity value is greater than or equal to the preset humidity threshold, it means that the indoor environment is relatively humid or has reached a comfortable humidity range. At this time, the water vapor generator unit can be controlled to be turned off to avoid excessive humidification and cause the indoor humidity to be too high; if the humidity value is less than the preset humidity threshold, it means that the indoor air is too dry and the humidity needs to be increased. At this time, the water vapor generator unit can be controlled to be turned on to release an appropriate amount of water vapor into the room to increase the indoor humidity.

[0102] In one embodiment of the present invention, in the purification mode, the process of controlling the operating state of the air purification subsystem according to the air conditioning parameters also includes: obtaining the indoor temperature value; calculating the temperature difference between the temperature value and the preset temperature difference; when the temperature difference is less than or equal to the preset temperature difference, controlling the air conditioner to turn on the fresh air mode; when the temperature difference is greater than the preset temperature difference, controlling the air conditioner to turn on the air conditioning mode.

[0103] Specifically, in the purification mode, in the process of controlling the operating status of the air purification subsystem according to the air conditioning parameters, the indoor temperature value can also be monitored in real time by the temperature sensor, and the temperature difference between the temperature value and the preset temperature difference can be calculated according to the built-in algorithm. If the temperature difference is less than or equal to the preset temperature difference, it means that the current indoor temperature is very close to the preset temperature. At this time, the air conditioner can be controlled to turn on the fresh air mode, and the indoor temperature is adjusted by natural ventilation to reduce energy consumption; if the temperature difference is greater than the preset temperature difference, it means that the current indoor temperature deviates greatly from the preset temperature expected by the user. At this time, the air conditioner can be controlled to turn on the air conditioning mode and adjust the cooling or heating function to quickly adjust the indoor temperature difference to within the preset temperature difference range.

[0104] In one embodiment of the present invention, determining the purification mode of the air conditioner according to the polluted gas parameters includes: calculating the concentration difference between the polluted gas concentration value and a preset concentration threshold; and determining the purification mode of the air conditioner according to the concentration difference.

[0105] Specifically, when determining the purification mode of the air conditioner based on the polluted gas parameters, the concentration difference between the polluted gas concentration value and the preset concentration threshold can be calculated, that is, the degree of deviation between the current indoor polluted gas concentration and the standard safety or comfort concentration threshold, and the purification mode of the air conditioner can be determined based on the concentration difference, so that the indoor environment is always in the best purification mode to ensure that the indoor air is always in excellent condition.

[0106] In one embodiment of the present invention, the purification mode of the air conditioner is determined according to the concentration difference, including: when the concentration difference is less than a preset concentration difference, determining the purification mode to be a low-temperature plasma purification mode or a photocatalytic purification mode; when the concentration difference is greater than or equal to the preset concentration difference, determining the purification mode to be a deep purification mode.

[0107] Specifically, when determining the purification mode of the air conditioner according to the concentration difference, if the concentration difference is less than the preset concentration difference, it means that the current level of indoor pollution is relatively light. At this time, a milder and more energy-efficient purification mode can be selected, namely, the low-temperature plasma purification mode or the photocatalytic purification mode, which uses the strong oxidizing property of the low-temperature plasma or the photocatalytic chemical reaction to decompose the polluted gases in the air at a lower energy consumption; if the concentration difference is greater than or equal to the preset concentration difference, it means that the indoor pollution is relatively serious, and the purification mode can be selected as the deep purification mode, that is, a variety of purification modes can be combined, including but not limited to simultaneously turning on low-temperature plasma purification, photocatalytic purification, etc.

[0108] In summary, according to the control method of the air conditioner in an embodiment of the present invention, by real-time monitoring and obtaining indoor polluted gas parameters and air conditioning parameters, the current optimal purification mode of the air conditioner can be determined according to the polluted gas parameters, and in the determined purification mode, the operating state of the air purification subsystem can be accurately controlled according to the air conditioning parameters. This can quickly and efficiently reduce the concentration of pollutants, kill bacteria and microorganisms, and improve indoor air quality while ensuring user safety. At the same time, it can reduce unnecessary energy consumption and improve energy utilization efficiency.
