[0044] This disclosure provides an air conditioning system, including a fresh air fan, an exhaust fan, an indoor air concentration sensor, an indoor temperature sensor, an indoor humidity sensor, an outdoor air concentration sensor, an outdoor temperature sensor, and an outdoor humidity sensor. The fresh air fan is located within a fresh air duct; when the fresh air fan is activated, outdoor air enters the room through the fresh air duct. The exhaust fan is located within an exhaust duct; when the exhaust fan is activated, indoor air is exhausted to the outside through the exhaust duct. The indoor air concentration sensor is used to acquire the indoor PM2.5 concentration, and the outdoor air concentration sensor is used to acquire the outdoor PM2.5 concentration. The indoor temperature sensor is used to acquire the indoor temperature, and the outdoor temperature sensor is used to acquire the outdoor temperature. The indoor humidity sensor is used to acquire the indoor humidity, and the outdoor humidity sensor is used to acquire the outdoor humidity.

[0045] Combination Figure 1 As shown, this disclosure provides a method for controlling an air conditioning system, including:

[0046] S10: Obtain the fault status of the indoor and outdoor concentration sensors;

[0047] S11: When both sensors are working, control the on / off status of the fresh air fan and exhaust fan of the air conditioning system according to the relationship between the indoor PM2.5 concentration and the outdoor PM2.5 concentration.

[0048] S12: When the indoor concentration sensor is working and the outdoor concentration sensor is faulty, control the on / off status of the fresh air fan and the exhaust fan according to the indoor PM2.5 concentration.

[0049] S13: In the event of an indoor concentration sensor malfunction and an outdoor concentration sensor functioning, control the on / off status of the fresh air fan and exhaust fan based on the outdoor PM2.5 concentration.

[0050] In this embodiment, the air conditioning system has an indoor concentration sensor and an outdoor concentration sensor. Based on the fault status of the two sensors, different methods are used to control the on / off state of the fresh air fan and the exhaust fan. This way, even if one sensor malfunctions, the fresh air fan and exhaust fan can still be effectively controlled to regulate the indoor PM2.5 concentration.

[0051] Optionally, step S11 involves controlling the on / off state of the fresh air fan and exhaust fan of the air conditioning system based on the relationship between the indoor and outdoor PM2.5 concentrations, including:

[0052] When the indoor PM2.5 concentration is higher than the outdoor PM2.5 concentration, control the fresh air fan to turn on and the exhaust fan to turn on.

[0053] When the indoor PM2.5 concentration is less than or equal to the outdoor PM2.5 concentration, the fresh air fan and exhaust fan should be turned off.

[0054] In this embodiment, when the indoor PM2.5 concentration is greater than the outdoor PM2.5 concentration, the outdoor air quality is better. At this time, both the fresh air fan and the exhaust fan are turned on to rapidly circulate indoor and outdoor air, allowing fresh outdoor air to enter the room and thus reducing the indoor PM2.5 concentration. When the indoor PM2.5 concentration is less than or equal to the outdoor PM2.5 concentration, the indoor air quality is better. At this time, both the fresh air fan and the exhaust fan are turned off to maintain indoor air quality.

[0055] Optionally, step S12, controlling the on / off state of the fresh air fan and exhaust fan according to the indoor PM2.5 concentration, includes:

[0056] When the indoor PM2.5 concentration is less than or equal to the first concentration value, the fresh air fan and exhaust fan should be turned off.

[0057] If the indoor PM2.5 concentration is greater than or equal to the second concentration value, control the fresh air fan to turn on and the exhaust fan to turn on.

[0058] When the indoor PM2.5 concentration is greater than the first concentration value but less than the second concentration value, the fresh air fan is turned on and the exhaust fan is turned off.

[0059] The second concentration value is greater than the first concentration value.

[0060] In this embodiment, due to a malfunction of the outdoor concentration sensor, the indoor PM2.5 concentration detected by the indoor concentration sensor controls the fresh air fan and exhaust fan. When the indoor PM2.5 concentration is greater than or equal to a second concentration, both the fresh air fan and exhaust fan are turned on simultaneously to rapidly circulate indoor and outdoor air, thereby regulating indoor air quality. When the indoor PM2.5 concentration is less than or equal to a first concentration, both the fresh air fan and exhaust fan are turned off simultaneously to maintain indoor air quality. When the first concentration is less than the indoor PM2.5 concentration and less than the second concentration, the fresh air fan is turned on and the exhaust fan is turned off to regulate indoor air quality. Optionally, the first concentration is 30 mg / m³. 3 The second concentration was 75 mg / m³. 3 .

[0061] In this embodiment, if the outdoor concentration sensor malfunctions, the air conditioning system has difficulty determining the relative concentrations of PM2.5 indoors and outdoors. To more effectively regulate air quality, the first and second concentrations are determined as follows:

[0062] First, the current indoor PM2.5 concentration is obtained. An initial value for the first concentration is set to be lower than the current indoor PM2.5 concentration, and an initial value for the second concentration is set to be higher than the current indoor PM2.5 concentration. Based on this, the fresh air fan turns on and the exhaust fan turns off. Then, after time t, the indoor PM2.5 concentration is obtained. If the indoor concentration decreases after time t, it indicates that the outdoor PM2.5 concentration is less than the indoor PM2.5 concentration. If the indoor concentration increases after time t, it indicates that the outdoor PM2.5 concentration is greater than the indoor PM2.5 concentration.

[0063] Next, after time t, as the indoor concentration decreases, the final value of the first concentration is determined based on the rate of decrease; the faster the rate of decrease, the smaller the final value of the first concentration. A faster rate of decrease indicates a greater difference in PM2.5 concentration between indoors and outdoors, meaning outdoor air quality is significantly better than indoors. With a smaller final value of the first concentration, the fresh air fan will operate for a longer period, which is beneficial for introducing more outdoor air into the room. The final value of the second concentration is obtained by adding a set difference to the final value of the first concentration. Here, the final value of the first concentration is still less than the current indoor PM2.5 concentration.

[0064] Meanwhile, if the indoor concentration increases after time t, the final value of the first concentration is determined based on the rate of increase; the faster the rate of increase, the larger the final value of the first concentration. A faster rate of increase indicates a greater difference in PM2.5 concentration between indoors and outdoors, meaning the indoor air quality is significantly better than the outdoor air quality. When the final value of the first concentration is large, the fresh air fan will operate for a shorter period. If the indoor concentration increases slightly, both the fresh air fan and the exhaust fan will remain off to prevent a large amount of poor-quality outdoor air from entering the room. Here, the final value of the first concentration is still lower than the current indoor PM2.5 concentration.

[0065] Optionally, step S13 involves controlling the on / off state of the fresh air fan and exhaust fan based on the outdoor PM2.5 concentration, including:

[0066] When the outdoor PM2.5 concentration is less than or equal to the third concentration value, control the fresh air fan to turn on and the exhaust fan to turn on.

[0067] When the outdoor PM2.5 concentration is greater than the third concentration value, the fresh air fan should be turned off and the exhaust fan should be turned on.

[0068] In this embodiment, the third concentration value is a suitable concentration value. When the outdoor PM2.5 concentration is less than or equal to the third concentration, the fresh air fan and exhaust fan are turned on simultaneously to facilitate rapid indoor-outdoor air circulation. When the outdoor PM2.5 concentration is greater than the third concentration, the fresh air fan is turned off and the exhaust fan is turned on to prevent a large amount of poor-quality outdoor air from entering the room. Simultaneously, if the indoor air quality is poor, it can reduce the outdoor PM2.5 concentration. In this way, even if the air conditioning system cannot accurately determine the relative concentrations of indoor and outdoor PM2.5, it can effectively regulate the indoor PM2.5 concentration.

[0069] Optionally, if both the indoor and outdoor concentration sensors malfunction, the fresh air fan can be turned off while the exhaust fan is turned on. In this way, when the air conditioning system cannot detect the indoor and outdoor PM2.5 concentrations, it only needs to operate the exhaust fan. If the indoor PM2.5 concentration is high, this will reduce the concentration; if the outdoor PM2.5 concentration is high, this will prevent a large amount of poor-quality outdoor air from entering the room.

[0070] like Figure 2 As shown in the embodiments of this disclosure, another method for controlling an air conditioning system is provided, including:

[0071] S20: Obtain outdoor and indoor temperatures;

[0072] S21: Control the on / off status of the fresh air fan and exhaust fan of the air conditioning system according to the outdoor temperature and indoor temperature.

[0073] Optionally, step S21, controlling the on / off state of the fresh air fan and exhaust fan of the air conditioning system based on the outdoor temperature and indoor temperature, includes:

[0074] When the indoor temperature is higher than the outdoor temperature and the indoor temperature is greater than or equal to the first temperature, control the fresh air fan to turn on and the exhaust fan to turn on, and control the air conditioning system to operate in cooling mode.

[0075] When the indoor temperature is higher than the outdoor temperature, and the indoor temperature is lower than the first temperature but higher than or equal to the second temperature, the fresh air fan and the exhaust fan are turned on.

[0076] When the indoor temperature is higher than the outdoor temperature, and the indoor temperature is lower than the second temperature but higher than or equal to the third temperature, control the fresh air fan to turn on and the exhaust fan to turn off;

[0077] When the indoor temperature is below the third temperature, control the new fan to turn off and the exhaust fan to turn off.

[0078] In this embodiment, when the indoor temperature is higher than the outdoor temperature, the fresh air fan is turned on to introduce outdoor air into the room, thereby lowering the indoor temperature. However, the control of the exhaust fan and air conditioning system modes needs to be determined based on the indoor temperature. When the indoor temperature is ≥ the first temperature, the indoor temperature is high, and simply introducing outdoor air will not have a significant cooling effect. In this case, the air conditioning system is controlled to operate in cooling mode for rapid cooling. When the second temperature is ≤ the indoor temperature < the first temperature, the fresh air fan and exhaust fan are turned on to rapidly circulate indoor and outdoor air. In this case, introducing outdoor air is sufficient to achieve the desired cooling effect, eliminating the need to activate cooling mode and saving energy. When the third temperature is ≤ the indoor temperature < the second temperature, the fresh air fan is turned on and the exhaust fan is turned off. At this point, the indoor temperature is already low but has not yet reached a level lower than the third temperature. Therefore, outdoor air continues to be introduced while preventing indoor air from being exhausted to the outside, ensuring the stability of the indoor temperature. Until the indoor temperature is < the third temperature, both the fresh air fan and exhaust fan are turned off to further ensure the stability of the indoor temperature.

[0079] In this embodiment, optionally, the first temperature is 30°C, the second temperature is 25°C, and the third temperature is 20°C.

[0080] like Figure 3 As shown in the embodiments of this disclosure, another method for controlling an air conditioning system is provided, including:

[0081] S30: Obtain outdoor and indoor humidity;

[0082] S31: Control the on / off status of the fresh air fan and exhaust fan of the air conditioning system based on the outdoor humidity and indoor humidity.

[0083] Optionally, step S31, controlling the on / off state of the fresh air fan and exhaust fan of the air conditioning system based on the outdoor humidity and indoor humidity, includes:

[0084] When the indoor humidity is greater than the outdoor humidity and the indoor humidity is greater than or equal to the first humidity, control the fresh air fan to turn on and the exhaust fan to turn on, and control the air conditioning system to operate in heating mode.

[0085] When the indoor humidity is greater than the outdoor humidity, and the indoor humidity is less than the first humidity but greater than or equal to the second humidity, control the fresh air fan to turn on and the exhaust fan to turn on.

[0086] When the indoor humidity is greater than the outdoor humidity, and the indoor humidity is less than the second humidity but greater than or equal to the third humidity, the fresh air fan and the exhaust fan should be turned off.

[0087] When the indoor humidity is less than the third humidity level, the air conditioning system is controlled to operate in humidification mode, and the humidification mode is controlled to stop when the indoor humidity is greater than or equal to the third humidity level.

[0088] In this embodiment, when the indoor humidity is higher than the outdoor humidity, the fresh air fan is turned on to introduce outdoor air into the room, thereby reducing the indoor humidity. However, the control of the exhaust fan and air conditioning system modes needs to be determined based on the indoor humidity. When the indoor humidity is greater than or equal to the first humidity level, the indoor humidity is high, and the dehumidification effect is poor simply by introducing outdoor air. In this case, the air conditioning system is controlled to operate in heating mode for rapid dehumidification. When the second humidity level is less than or equal to the indoor humidity level but less than the first humidity level, the fresh air fan and exhaust fan are turned on to rapidly circulate indoor and outdoor air. In this case, the ideal dehumidification effect can be achieved by introducing outdoor air, and there is no need to turn on the heating mode, thus saving energy. When the third humidity level is less than or equal to the indoor humidity level but less than the second humidity level, the indoor humidity has reached a suitable range. The fresh air fan and exhaust fan are turned off to ensure the stability of the indoor humidity. When the indoor humidity level is less than the third humidity level, the indoor humidity is too low, affecting the user experience. The air conditioning system is controlled to operate in humidification mode, and the humidification mode is controlled to stop when the indoor humidity is greater than or equal to the third humidity level.

[0089] like Figure 4 As shown, this embodiment of the present disclosure provides a device for controlling an air conditioner, including a humidity module S22 and a control module S23. The humidity module S22 is configured to acquire outdoor humidity and indoor humidity; the control module S23 is configured to control the on / off state of the fresh air fan and exhaust fan of the air conditioning system based on the outdoor humidity and indoor humidity.

[0090] In the above embodiments, the control logic for the air conditioning system's fresh air fan and exhaust fan is divided into PM2.5 concentration, temperature, and humidity components, referred to as the first logic, second logic, and third logic, respectively. These three logics may conflict in certain situations. For example, if the indoor PM2.5 concentration is greater than or equal to the second concentration, the third temperature is less than or equal to the indoor temperature but less than the second temperature, and the third humidity is less than or equal to the indoor humidity but less than the second humidity, then according to the first logic, both the fresh air fan and exhaust fan should be turned on simultaneously; according to the second logic, the fresh air fan should be on and the exhaust fan should be off; and according to the third logic, both the fresh air fan and exhaust fan should be off simultaneously. The purpose of the first logic is to ensure that the indoor PM2.5 concentration is less than the first concentration value; the purpose of the second logic is to ensure that the indoor temperature is less than the third temperature; and the purpose of the third logic is to ensure that the third humidity is less than or equal to the indoor humidity but less than the second humidity. These three purposes are referred to as the first purpose, the second purpose, and the third purpose, respectively. Figure 5 As shown, in cases where the first, second, and third logics conflict in pairs or all three conflict simultaneously:

[0091] S40: Control the fresh air fan and exhaust fan to run simultaneously for m time, and obtain the indoor PM2.5 concentration change rate, indoor temperature change rate, and indoor humidity change rate;

[0092] S41: Obtain the maximum and minimum rates of change among the three: concentration change rate, temperature change rate, and humidity change rate;

[0093] S42: Control the air conditioning system to execute the corresponding control logic based on the maximum and minimum rates of change.

[0094] In this embodiment, the concentration change rate, temperature change rate, and humidity change rate are ranked from largest to smallest as maximum change rate, intermediate change rate, and minimum change rate. The logic corresponding to the minimum change rate is executed first; for example, if the concentration change rate is the smallest, the first logic is executed first, and after achieving the first objective, both the fresh air fan and the exhaust fan are turned off. Then, the logic corresponding to the maximum change rate is executed; for example, if the temperature change rate is the largest, the second logic is executed to achieve the second objective, and after achieving the second objective, both the fresh air fan and the exhaust fan are turned off. During the execution of the second logic, the indoor PM2.5 concentration changes simultaneously, but the change is small. Finally, the air conditioning system is controlled to operate in the corresponding mode to adjust the indoor parameters corresponding to the intermediate change rate; for example, if the air conditioning system operates in humidification / heating mode, the indoor humidity will reach the third objective. Here, if the intermediate change rate corresponds to the PM2.5 concentration, the air conditioning system is regulated through purification mode; if the intermediate change rate corresponds to temperature, the air conditioning system is regulated through cooling / heating mode. Here, the logic corresponding to the maximum rate of change saves considerable energy and has minimal impact on indoor parameters corresponding to the minimum rate of change. Furthermore, by adjusting the indoor parameters corresponding to the intermediate rate of change through the corresponding mode of the air conditioning system, the stability of the indoor parameters corresponding to both the maximum and minimum rates of change can be effectively ensured. In this way, the indoor parameters corresponding to the maximum and intermediate rates of change can be accurately controlled to their respective objectives, while the indoor parameters corresponding to the minimum rate of change can be controlled to be close to their respective objectives. This effectively regulates the concentration of PM2.5, temperature, and humidity in indoor air, greatly satisfying users' needs for indoor air quality.
