The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0029] like Figure 1 As shown, in a first aspect, embodiments of this application provide an air conditioner control method, which includes S10 to S20, and can control the operating noise of the air conditioner 1 according to the upper limit of the noise allowable in the current environment, so as to avoid causing discomfort to the user.

[0030] Here, the air conditioner 1 has an indoor side and an outdoor side arranged opposite to each other. The type of air conditioner 1 can be determined according to actual needs, and can be, for example, a split air conditioner such as a wall-mounted air conditioner / cabinet air conditioner, or an integrated air conditioner such as a window air conditioner. This application embodiment does not limit this. When the air conditioner 1 is a split air conditioner, the indoor side is the indoor unit of the air conditioner 1, and the outdoor side is the outdoor unit of the air conditioner 1; when the air conditioner 1 is an integrated air conditioner, the indoor side is the indoor end structure facing inward in the air conditioner 1, and the outdoor side is the outdoor end structure facing outward in the air conditioner 1.

[0031] The outdoor side is equipped with an outdoor heat exchanger, an outdoor fan, and a condensate atomizing device. The condensate atomizing device is used to atomize the condensate to cool the outdoor heat exchanger with the resulting low-temperature water mist. For example, the indoor fan can blow the low-temperature water mist formed by the condensate atomizing device toward the outdoor heat exchanger to force rapid heat exchange between the low-temperature water mist and the outdoor heat exchanger.

[0032] S10: Determine whether the outdoor light intensity is less than or equal to the preset light intensity.

[0033] Here, the outdoor light intensity can be determined in real time by a light sensor installed on the outdoor side. A preset light intensity can be pre-set in the control system of air conditioner 1 to serve as a marker for the current actual time. When the outdoor light intensity is less than or equal to the preset light intensity, it can be determined that the current period is nighttime with lower outdoor light intensity and relatively lower outdoor ambient temperature; when the outdoor light intensity is greater than the preset light intensity, it can be determined that the current period is daytime with higher outdoor light intensity and relatively higher outdoor ambient temperature.

[0034] S20: In response to determining that the outdoor light intensity is less than or equal to the preset light intensity, control the condensate atomizing device to start and control the outdoor fan to reduce its operating speed.

[0035] When the outdoor light intensity is determined to be less than or equal to the preset light intensity, it can be determined that the current outdoor light intensity is low, and the current time is during the nighttime period when the outdoor ambient temperature is low and natural and human activity noise is low. At this time, the user is in a resting state where they are more sensitive to environmental noise, and the upper limit of the environmental noise that the user can tolerate is relatively low. It is necessary to control the outdoor fan to reduce the operating speed of the outdoor fan to reduce the operating noise generated by the outdoor fan, so that the operating noise of air conditioner 1 is reduced to a more comfortable noise range for the user, thereby improving the quietness of the user's environment. At the same time, the condensate atomizing device is activated to atomize the condensate, and then the low-temperature water mist formed is used to cool the outdoor heat exchanger to compensate for the cooling capacity shortfall caused by the reduced operating speed of the outdoor fan. This ensures that the cooling capacity provided to the outdoor heat exchanger by the outdoor fan and the condensate atomizing device remains constant or basically constant, thereby ensuring that the outdoor heat exchanger can maintain an ideal temperature range and maintain optimal condensation heat exchange efficiency.

[0036] Compared with related technologies, the air conditioner control method provided in this application determines the noise limit of the current time and environment based on the outdoor light intensity. When the outdoor light intensity is less than or equal to the preset light intensity, on the one hand, it controls the condensate atomizing device to start, ensuring that the cooling capacity provided to the outdoor heat exchanger by the outdoor fan and the condensate atomizing device remains constant or basically constant, so that the outdoor heat exchanger can maintain better condensation heat exchange efficiency. On the other hand, it controls the outdoor fan to reduce the operating speed, so as to reduce the operating wind noise generated by the outdoor fan and the overall noise of the air conditioner 1, improve the quietness of the user's environment, and avoid causing user discomfort, thereby taking into account both the cooling capacity requirements of the outdoor heat exchanger and the user's quiet use requirements.

[0037] like Figure 2 As shown, in some embodiments, the air conditioner control method may include S30 to S50.

[0038] S30: In response to determining that the outdoor light intensity is greater than the preset light intensity, determine whether the temperature of the outdoor heat exchanger is greater than or equal to the first preset temperature.

[0039] Here, the temperature of the outdoor heat exchanger can be measured in real time by a temperature sensor installed on the outdoor heat exchanger; the first preset temperature can be preset in the control system of air conditioner 1 and used as a criterion for judging the cooling capacity demand of the outdoor heat exchanger. When it is determined that the outdoor light intensity is greater than the preset light intensity, it can be determined that the current time is during the daytime when the outdoor light intensity is high and the outdoor ambient temperature is relatively high. Natural noise and human activity noise are also higher, and the user's tolerance for environmental noise is higher, with a larger upper limit for the environmental noise that the user can tolerate. At this time, it can be further determined whether the temperature of the outdoor heat exchanger is greater than or equal to the first preset temperature to determine the level of cooling capacity demand of the outdoor heat exchanger.

[0040] S40: In response to determining that the temperature of the outdoor heat exchanger is greater than or equal to the first preset temperature, control the condensate atomization device to start.

[0041] If the outdoor heat exchanger's temperature is determined to be greater than or equal to the first preset temperature, it indicates a high cooling capacity requirement. The indoor fan, operating at its current speed, may not adequately meet this demand. In this case, the condensate atomizing device can be activated to atomize the condensate, using the resulting low-temperature water mist to cool the outdoor heat exchanger. This allows both the outdoor fan and the atomizing device to jointly provide cooling, significantly increasing the available cooling capacity and thus matching the higher cooling capacity requirement. This allows the outdoor heat exchanger's temperature to gradually decrease to the ideal range.

[0042] S50: In response to determining whether the temperature of the outdoor heat exchanger is lower than the first preset temperature, control the condensate atomizing device to remain closed.

[0043] When the temperature of the outdoor heat exchanger is determined to be lower than the first preset temperature, it can be determined that the cooling capacity requirement of the outdoor heat exchanger is relatively high. The indoor fan, running at its current speed, can adequately meet the cooling requirements of the outdoor heat exchanger. At this time, the condensate atomizing device can be kept closed, while the condensate produced by the air conditioner 1 is collected and stored. After the condensate atomizing device meets the start-up conditions and starts, it can atomize the stored condensate, thereby using the formed low-temperature water mist to cool the outdoor heat exchanger, ensuring that the condensate atomizing device has sufficient condensate reserves.

[0044] In some embodiments, the air conditioner control method may include S70.

[0045] S70: In response to the condensate atomizing device being in operation, the atomization rate of the condensate atomizing device is controlled according to the outdoor light intensity.

[0046] When the condensate atomizing device is confirmed to be in operation, its atomization rate can be controlled based on the outdoor light intensity. For example, the atomization rate of the condensate atomizing device and the outdoor light intensity can have a negative correlation. In other words, as the outdoor light intensity gradually increases, the atomization rate of the condensate atomizing device gradually decreases; as the outdoor light intensity gradually decreases, the atomization rate of the condensate atomizing device gradually increases.

[0047] When the atomization rate of the condensate atomizing device is high, the amount of low-temperature water mist formed by the device is large, and the device can provide a large amount of cooling capacity to the outdoor heat exchanger, resulting in a strong cooling effect. Conversely, when the atomization rate is low, the amount of low-temperature water mist formed by the device is small, and the device can provide a small amount of cooling capacity to the outdoor heat exchanger, resulting in a weak cooling effect.

[0048] The atomization rate of the condensate atomizing device can be changed by controlling different operating parameters, and this application embodiment does not limit this. For example, the condensate atomizing device may include a water pump and an atomizing device. The water pump is used to pump water from the water tray / condensate storage tank to the atomizing device, and the atomizing device is used to atomize the condensate pumped to the vicinity of the atomizing device. The type of atomizing device can be determined according to actual needs, and may include, for example, an ultrasonic atomizing device, a jet atomizing device, etc., and this application embodiment does not limit this. Accordingly, the atomization rate of the condensate atomizing device can be changed by controlling control parameters such as the water pump flow rate, the vibration frequency of the ultrasonic atomizing device, and the flow rate of the jet atomizing device.

[0049] By setting S70, the atomization rate of the condensate atomizing device can be adaptively adjusted according to the outdoor light intensity, so that the atomization rate of the condensate atomizing device can change with the current outdoor ambient temperature / current ambient noise limit, thereby making the atomization rate of the condensate atomizing device more compatible with the current outdoor ambient temperature / current ambient noise limit.

[0050] The specific steps for controlling the atomization rate of the condensate atomizing device based on outdoor light intensity can be determined according to actual needs, and this application does not limit this. In some examples, proportional-integral-derivative control (PID control) can be used. For example... Figure 3 As shown, S70 may include S71 to S73.

[0051] S71: Determine the set temperature of the outdoor heat exchanger based on the current speed of the outdoor fan, the current atomization rate of the condensate atomizing device, and the current outdoor ambient temperature.

[0052] Here, the given temperature of the outdoor heat exchanger refers to the ideal temperature of the outdoor heat exchanger predicted based on the current operating parameters, that is, the target temperature when the outdoor heat exchanger is temperature controlled. A prediction model for the given temperature of the outdoor heat exchanger can be predetermined. The input variables of this prediction model include the current speed of the outdoor fan, the current atomization rate of the condensate atomizing device, and the current outdoor ambient temperature. The output of this prediction model is the given temperature of the outdoor heat exchanger.

[0053] S72: Determine the control quantity for proportional-integral-derivative control based on the temperature difference between the given temperature and the actual temperature of the outdoor heat exchanger.

[0054] Here, the temperature difference between the given temperature and the actual temperature of the outdoor heat exchanger can be determined, and this temperature difference can be used as the control deviation of proportional-integral-derivative (PID) control. Furthermore, this control deviation can be linearly combined proportionally, integrally, and derivatively to obtain the control quantity for PID control.

[0055] S73: Determine the atomization rate adjustment amount of the condensate atomizing device based on the control quantity of proportional-integral-derivative control and the outdoor light intensity, and adjust the atomization rate of the condensate atomizing device according to the atomization rate adjustment amount.

[0056] After determining the control quantity of the proportional-integral-derivative (PID) control, the atomization rate adjustment of the condensate atomizing device can be determined based on the PID control quantity, the real-time acquired outdoor light intensity, and a pre-determined atomization rate adjustment calculation model. Here, the inputs to the atomization rate adjustment calculation model can include the PID control quantity and the outdoor light intensity, while the output of the model is the atomization rate adjustment. Thus, by inputting the PID control quantity and the outdoor light intensity into the atomization rate adjustment calculation model, the atomization rate adjustment can be obtained.

[0057] After determining the atomization rate adjustment amount, the atomization rate of the condensate atomizing device can be increased or decreased according to the atomization rate adjustment amount, so that the atomization rate of the condensate atomizing device is adjusted to the target atomization rate, which is the sum of the current atomization rate of the condensate atomizing device and the atomization rate adjustment amount.

[0058] In some embodiments, the air conditioner control method may include S80.

[0059] S80: Controls the operating speed of the outdoor fan according to the outdoor light intensity.

[0060] Here, the operating speed of the outdoor fan can be controlled based on the outdoor light intensity. For example, the operating speed of the outdoor fan and the outdoor light intensity can be positively correlated. In other words, as the outdoor light intensity gradually increases, the operating speed of the outdoor fan gradually increases; as the outdoor light intensity gradually decreases, the operating speed of the outdoor fan gradually decreases.

[0061] When the outdoor fan operates at a higher speed, the convective airflow generated by the outdoor fan is larger, and the outdoor fan can provide a larger amount of cooling capacity to the outdoor heat exchanger, resulting in a stronger cooling effect on the outdoor heat exchanger. When the outdoor fan operates at a lower speed, the convective airflow generated by the outdoor fan is smaller, and the outdoor fan can provide a smaller amount of cooling capacity to the outdoor heat exchanger, resulting in a weaker cooling effect on the outdoor heat exchanger.

[0062] By setting S80, the operating speed of the outdoor fan can be adaptively adjusted according to the outdoor light intensity, so that the operating speed of the outdoor fan can change with the current outdoor ambient temperature / current ambient noise limit, thereby making the operating speed of the outdoor fan more compatible with the current outdoor ambient temperature / current ambient noise limit.

[0063] Furthermore, S70 and S80 can be set simultaneously, that is, the atomization rate of the condensate atomizing device and the operating speed of the outdoor fan can be controlled simultaneously according to the outdoor light intensity, so that the atomization rate of the condensate atomizing device and the operating speed of the outdoor fan can change with the current outdoor ambient temperature / current ambient noise limit. For example, the atomization rate of the condensate atomizing device and the outdoor light intensity can have a negative correlation, while the operating speed of the outdoor fan and the outdoor light intensity can have a positive correlation.

[0064] Here, when the outdoor light intensity is greater than the preset light intensity, the condensate atomizing device is started and the outdoor fan speed is reduced; when the outdoor light intensity is less than or equal to the preset light intensity, if the temperature of the outdoor heat exchanger is greater than or equal to the first preset temperature or other start-up conditions of the condensate atomizing device are met, the condensate atomizing device can be started. Subsequently, during the operation of the condensate atomizing device, according to S70 and S80, the atomization rate of the condensate atomizing device and the operating speed of the outdoor fan change with the change of outdoor light intensity. As outdoor light intensity gradually increases, the atomization rate of the condensate atomizing device gradually decreases, while the operating speed of the outdoor fan gradually increases. Conversely, as outdoor light intensity gradually decreases, the operating speed of the outdoor fan gradually decreases, while the atomization rate of the condensate atomizing device gradually increases. This reduces the operating noise of the outdoor fan and the overall noise of the air conditioner 1, improving quiet operation. Furthermore, it gradually increases the cooling capacity provided by the condensate atomizing device to compensate for the cooling capacity shortfall caused by the decrease in the operating speed of the outdoor fan, ensuring that the cooling capacity provided to the outdoor heat exchanger by the outdoor fan and the condensate atomizing device remains constant or essentially constant.

[0065] The specific steps for controlling the atomization rate of the condensate atomizing device based on outdoor light intensity can be determined according to actual needs, and this application does not limit this. In some examples, proportional-integral-derivative control (PID control) can be used. For example... Figure 4 As shown, S80 may include S81 to S83.

[0066] S81: Determine the set temperature of the outdoor heat exchanger based on the current speed of the outdoor fan, the current atomization rate of the condensate atomizing device, and the current outdoor ambient temperature.

[0067] Here, the given temperature of the outdoor heat exchanger refers to the ideal temperature of the outdoor heat exchanger predicted based on the current operating parameters, that is, the target temperature when the outdoor heat exchanger is temperature controlled. A prediction model for the given temperature of the outdoor heat exchanger can be predetermined. The input variables of this prediction model include the current speed of the outdoor fan, the current atomization rate of the condensate atomizing device, and the current outdoor ambient temperature. The output of this prediction model is the given temperature of the outdoor heat exchanger.

[0068] S82: Determine the control quantity for proportional-integral-derivative control based on the temperature difference between the given temperature and the actual temperature of the outdoor heat exchanger.

[0069] Here, the temperature difference between the given temperature and the actual temperature of the outdoor heat exchanger can be determined, and this temperature difference can be used as the control deviation of proportional-integral-derivative (PID) control. Furthermore, this control deviation can be linearly combined proportionally, integrally, and derivatively to obtain the control quantity for PID control.

[0070] S83: Determine the speed adjustment amount of the outdoor fan based on the control quantity of proportional-integral-derivative control and the outdoor light intensity, and adjust the speed of the outdoor fan according to the speed adjustment amount.

[0071] After determining the control quantity of proportional-integral-derivative (PID) control, the outdoor fan speed regulation can be determined based on the PID control quantity, the real-time acquired outdoor light intensity, and a pre-determined outdoor fan speed regulation calculation model. Here, the inputs to the outdoor fan speed regulation calculation model can include the PID control quantity and the outdoor light intensity, while the output of the model is the outdoor fan speed regulation. Thus, by inputting the PID control quantity and the outdoor light intensity into the outdoor fan speed regulation calculation model, the outdoor fan speed regulation can be obtained.

[0072] After determining the speed adjustment amount of the outdoor fan, the speed of the outdoor fan can be increased or decreased according to the speed adjustment amount, so that the speed of the outdoor fan is adjusted to the target speed, which is the sum of the current speed of the outdoor fan and the speed adjustment amount.

[0073] like Figure 5 As shown, for example, prior to S71 / S81, the air conditioner control method may include S61 to S62.

[0074] S61: Obtain historical operating data of air conditioner 1. The historical operating data includes historical temperature data of outdoor heat exchanger, historical operating speed data of outdoor fan, historical atomization rate data of condensate atomizing device, and historical outdoor ambient temperature data.

[0075] S62: Based on the historical operating data of air conditioner 1, determine the prediction model for the given temperature of the outdoor heat exchanger.

[0076] The type of prediction model for the given temperature of the outdoor heat exchanger can be determined according to actual needs, and this application embodiment does not limit this. For example, historical operating data of the air conditioner 1 can be used as sample data, and the model can be trained based on learning algorithms such as linear regression, artificial neural network, or decision tree algorithms to obtain prediction models for the given temperature of the outdoor heat exchanger, such as linear regression prediction models, artificial neural network prediction models, or decision tree prediction models. The input layer of the above prediction model includes the current speed of the outdoor fan, the current atomization rate of the condensate atomizing device, and the current outdoor ambient temperature, and the output layer of the above prediction model includes the given temperature of the outdoor heat exchanger.

[0077] Thus, in S71 / S81, the current speed of the outdoor fan, the current atomization rate of the condensate atomizing device, and the current outdoor ambient temperature can be input into the prediction model of the given temperature of the outdoor heat exchanger, and then the prediction model of the given temperature of the outdoor heat exchanger can output the given temperature of the outdoor heat exchanger.

[0078] Secondly, embodiments of this application provide an air conditioner control device for controlling the air conditioner 1 described above. The air conditioner control device includes: a light intensity comparison circuit configured to determine whether the outdoor light intensity is less than or equal to a preset light intensity; and a misting on / off control circuit configured to control the condensate misting device to start in response to determining that the outdoor light intensity is less than or equal to the preset light intensity.

[0079] like Figure 6 As shown, in a third aspect, embodiments of this application provide an air conditioner 1. The air conditioner 1 has an indoor side and an outdoor side disposed opposite to each other, and includes an outdoor heat exchanger, an outdoor fan, a condensate atomizing device, a processor 10, and a memory 20. The outdoor heat exchanger, the outdoor fan, and the condensate atomizing device are respectively disposed on the outdoor side. The condensate atomizing device is used to atomize condensate to cool the outdoor heat exchanger. The memory 20 stores a computer program, which, when executed by the processor 10, implements the air conditioner control method as provided in any of the above embodiments.

[0080] The type of air conditioner 1 can be determined according to actual needs. It can be a split-type air conditioner such as a wall-mounted air conditioner / cabinet air conditioner, or an integrated air conditioner such as a window air conditioner 1. This application embodiment does not limit this. When the air conditioner 1 is a split-type air conditioner, the indoor side is the indoor unit of the air conditioner 1, and the outdoor side is the outdoor unit of the air conditioner 1. When the air conditioner 1 is an integrated air conditioner, the indoor side is the indoor end structure facing the room, and the outdoor side is the outdoor end structure facing the room.

[0081] Processor 10 is connected to memory 20 and can perform various actions and processes according to the program stored in memory 20. Specifically, processor 10 can be an integrated circuit chip with signal processing capabilities. The processor 10 can be a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), off-the-shelf programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic device, or discrete hardware component, and can implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of this application. The general-purpose processor can be a microprocessor or any conventional processor, and can be based on x86 architecture or ARM architecture.

[0082] Memory 20 may be volatile or non-volatile, or may include both. Non-volatile memory may be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), or flash memory.
