It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0029] like Figure 1 As shown, in the first aspect, an embodiment of the present application provides 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 allowed in the current environment to avoid causing discomfort to the user.

[0030] Here, the air conditioner 1 has an indoor side and an outdoor side that are relatively arranged. The type of the air conditioner 1 can be determined according to actual needs, and can be a split air conditioner such as a wall-mounted air conditioner / cabinet air conditioner, an integrated air conditioner such as a window air conditioner, etc., which is not limited in the embodiments of the present application. 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 of the air conditioner 1 facing the indoor, and the outdoor side is the outdoor end structure of the air conditioner 1 facing the outdoor.

[0031] An outdoor heat exchanger, an outdoor fan and a condensation water atomizing device are provided on the outdoor side. The condensation water atomizing device is used to atomize the condensation water so as to use the formed low-temperature water mist to cool the outdoor heat exchanger. For example, the indoor fan can blow the low-temperature water mist formed by the condensation water atomizing device to the outdoor heat exchanger to force the low-temperature water mist and the outdoor heat exchanger to perform rapid heat exchange.

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

[0033] Here, the outdoor light intensity can be determined by real-time measurement by a light sensor arranged on the outdoor side. The preset light intensity can be pre-set in the control system of the air conditioner 1 as a judgment mark of 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 time is in the night time period when the outdoor light intensity is small and the outdoor ambient temperature is relatively low; when the outdoor light intensity is greater than the preset light intensity, it can be determined that the current time is in the day time period when the outdoor light intensity is large and the outdoor ambient temperature is relatively high.

[0034] S20: In response to determining that the outdoor light intensity is less than or equal to the preset light intensity, controlling the condensation water atomization device to start, and controlling the outdoor fan to reduce the operating speed.

[0035] When it is determined that the outdoor light intensity is less than or equal to the preset light intensity, it can be determined that the current outdoor light is small, and the current time is in the night time period with low outdoor ambient temperature, low natural noise and low human activity noise. At this time, the user is in a resting state where he is more sensitive to environmental noise, and the upper limit of the environmental noise that the user can tolerate is relatively small. It is necessary to control the outdoor fan to reduce the operating speed to reduce the operating wind noise generated when the outdoor fan is running, so that the operating noise of the air conditioner 1 is reduced to a noise range that is more comfortable for the user, thereby improving the quietness of the user's environment; at the same time, the condensate atomization device is controlled to start to atomize the condensate, and then the formed low-temperature water mist is used to cool the outdoor heat exchanger to compensate for the cold capacity gap caused by the reduction in the operating speed of the outdoor fan, and to ensure that the cold capacity provided by the outdoor fan and the condensate atomization device to the outdoor heat exchanger remains unchanged or basically unchanged, thereby ensuring that the outdoor heat exchanger can be maintained within the ideal temperature range, so that the outdoor heat exchanger can maintain better condensation heat exchange efficiency.

[0036] Compared with the related art, the air conditioner control method provided in the embodiment of the present application determines the allowable upper limit of noise at the current time and the current environment according to the outdoor light intensity. When the outdoor light intensity is less than or equal to the preset light intensity, on the one hand, the condensation water atomization device is controlled to start, to ensure that the cooling capacity provided to the outdoor heat exchanger by the outdoor fan and the condensation water atomization device remains unchanged or basically unchanged, so that the outdoor heat exchanger can maintain better condensation heat exchange efficiency. On the other hand, the outdoor fan is controlled to reduce the operating speed to reduce the operating wind noise generated by the outdoor fan during operation and the overall noise of the air conditioner 1, thereby improving the quietness of the user's environment and avoiding causing discomfort to the user, thereby taking into account the cooling capacity demand of the outdoor heat exchanger and the user's quiet use demand.

[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, determining whether the temperature of the outdoor heat exchanger is greater than or equal to a 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 pre-set in the control system of the air conditioner 1, and used as a sign for judging the cooling 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, the natural noise and human activity noise are high, the user's tolerance for environmental noise is high, and the upper limit of the environmental noise that the user can tolerate is high. 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 cooling 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, controlling the condensed water atomization device to start.

[0041] When it is determined that the temperature of the outdoor heat exchanger is greater than or equal to the first preset temperature, it can be determined that the cooling demand of the outdoor heat exchanger is relatively high, and the indoor fan may not be able to meet the cooling demand of the outdoor heat exchanger well when running at the current speed. At this time, the condensation water atomization device can be controlled to start, and the condensation water can be atomized by the condensation water atomization device to use the formed low-temperature water mist to cool the outdoor heat exchanger; in this way, the outdoor fan and the condensation water atomization device can jointly provide cooling to the outdoor heat exchanger, so that the cooling capacity that the outdoor heat exchanger can obtain is significantly increased, thereby matching and meeting the current high cooling demand of the outdoor heat exchanger, so that the temperature of the outdoor heat exchanger is gradually reduced to an ideal temperature range.

[0042] S50: In response to determining whether the temperature of the outdoor heat exchanger is less than a first preset temperature, controlling the condensed water atomizing device to remain closed.

[0043] When it is determined that the temperature of the outdoor heat exchanger is lower than the first preset temperature, it can be determined that the cooling demand of the outdoor heat exchanger is relatively high, and the indoor fan can better meet the cooling demand of the outdoor heat exchanger when running at the current speed. At this time, the condensate atomization device can be controlled to remain closed, and the condensate generated by the air conditioner 1 can be collected and stored; after the condensate atomization device subsequently meets the start-up conditions and starts, the condensate atomization device can atomize the stored condensate, and then use the formed low-temperature water mist to cool the outdoor heat exchanger, ensuring that the condensate atomization device has sufficient condensate reserves.

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

[0045] S70: In response to the condensed water atomization device being in an operating state, controlling an atomization rate of the condensed water atomization device according to outdoor light intensity.

[0046] When it is determined that the condensation water atomization device is in operation, the atomization rate of the condensation water atomization device can be controlled according to the outdoor light intensity. Exemplarily, the atomization rate of the condensation water atomization 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 condensation water atomization device gradually decreases; as the outdoor light intensity gradually decreases, the atomization rate of the condensation water atomization device gradually increases.

[0047] When the atomization rate of the condensation water atomization device is relatively large, the amount of low-temperature water mist formed by the condensation water atomization device is relatively large, the condensation water atomization device can provide a relatively large amount of cooling to the outdoor heat exchanger, and the condensation water atomization device has a relatively strong cooling effect on the outdoor heat exchanger; when the atomization rate of the condensation water atomization device is relatively small, the amount of low-temperature water mist formed by the condensation water atomization device is relatively small, the condensation water atomization device can provide a relatively small amount of cooling to the outdoor heat exchanger, and the condensation water atomization device has a relatively weak cooling effect on the outdoor heat exchanger.

[0048] The atomization rate of the condensate atomization device can be changed by controlling different operating parameters, which is not limited in the embodiments of the present application. Exemplarily, the condensate atomization device may include a water pump and an atomization device, the water pump is used to pump water from the water receiving tray / condensate storage tank to the atomization device, and the atomization device is used to atomize the condensate pumped to the vicinity of the atomization device; the type of atomization device can be determined according to actual needs, and for example, ultrasonic atomization devices, jet atomization devices, etc. can be used, which is not limited in the embodiments of the present application. Accordingly, the atomization rate of the condensate atomization device can be changed by controlling control parameters such as the flow rate of the water pump in the condensate atomization device, the vibration frequency of the ultrasonic atomization device, and the flow rate of the jet atomization device.

[0049] By setting S70, the atomization rate of the condensation water atomization device can be adaptively adjusted according to the outdoor light intensity, so that the atomization rate of the condensation water atomization device can change with the current outdoor ambient temperature / the current allowable upper limit of ambient noise, thereby making the atomization rate of the condensation water atomization device and the current outdoor ambient temperature / the current allowable upper limit of ambient noise more closely matched.

[0050] The specific steps of controlling the atomization rate of the condensed water atomization device according to the outdoor light intensity can be determined according to actual needs, and the embodiments of the present application are not limited to this. In some examples, proportional-integral-derivative control (PID control for short) can be used. Figure 3 As shown, S70 may include S71 to S73.

[0051] S71: Determine a given temperature of the outdoor heat exchanger according to a current rotation speed of the outdoor fan, a current atomization rate of the condensate atomization device, and a 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 temperature of the outdoor heat exchanger is controlled. A prediction model for the given temperature of the outdoor heat exchanger can be determined in advance, and the input variables of the prediction model include the current speed of the outdoor fan, the current atomization rate of the condensed water atomization device, and the current outdoor ambient temperature, and the output result of the prediction model is the given temperature of the outdoor heat exchanger.

[0053] S72: Determine the control amount of proportional-integral-differential control according to 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 used as the control deviation of the proportional integral differential control. Furthermore, the control deviation can be linearly combined according to the proportion, integration and differentiation to obtain the control amount of the proportional integral differential control.

[0055] S73: Determine an atomization rate adjustment amount of the condensation water atomization device according to a control amount of proportional-integral-differential control and outdoor light intensity, and adjust the atomization rate of the condensation water atomization device according to the atomization rate adjustment amount.

[0056] After determining the control amount of the proportional-integral-differential control, the atomization rate adjustment amount of the condensed water atomization device can be determined based on the control amount of the proportional-integral-differential control and the outdoor light intensity obtained in real time, and based on the predetermined atomization rate adjustment amount calculation model. Here, the input amount of the atomization rate adjustment amount calculation model may include the control amount of the proportional-integral-differential control and the outdoor light intensity, and the output result of the atomization rate adjustment amount calculation model is the atomization rate adjustment amount. In this way, the control amount of the proportional-integral-differential control and the outdoor light intensity can be input into the atomization rate adjustment amount calculation model to obtain the atomization rate adjustment amount.

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

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

[0059] S80: Control 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 according to the outdoor light intensity. Exemplarily, the operating speed of the outdoor fan and the outdoor light intensity can have a positive correlation. In other words, as the outdoor light intensity gradually increases, the operating speed of the outdoor fan gradually increases synchronously; as the outdoor light intensity gradually decreases, the operating speed of the outdoor fan gradually decreases synchronously.

[0061] When the operating speed of the outdoor fan is relatively high, the convection air volume formed by the outdoor fan is relatively large, the outdoor fan can provide a large amount of cooling to the outdoor heat exchanger, and the outdoor fan has a stronger cooling effect on the outdoor heat exchanger; when the operating speed of the outdoor fan is relatively low, the convection air volume formed by the outdoor fan is relatively small, the outdoor fan can provide a small amount of cooling to the outdoor heat exchanger, and the outdoor fan has 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 upper limit, thereby making the operating speed of the outdoor fan and the current outdoor ambient temperature / current ambient noise upper limit more matched.

[0063] Furthermore, S70 and S80 can be set at the same time, that is, the atomization rate of the condensed water atomization 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 condensed water atomization device and the operating speed of the outdoor fan can change with the current outdoor ambient temperature / current ambient noise allowable upper limit. Exemplarily, the atomization rate of the condensed water atomization device and the outdoor light intensity can have a negative correlation, and 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 condensation water atomization device is controlled to start and the outdoor fan is controlled to reduce the operating speed; 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 meets other starting conditions of the condensation water atomization device, the condensation water atomization device can be controlled to start. Subsequently, during the operation of the condensation water atomization device, according to S70 and S80, the atomization rate of the condensation water atomization device and the operating speed of the outdoor fan change respectively with the change of the outdoor light intensity. As the outdoor light intensity gradually increases, the atomization rate of the condensate atomization device gradually decreases, and 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, and the atomization rate of the condensate atomization device gradually increases. On the one hand, the operating wind noise of the outdoor fan and the overall noise of the air conditioner 1 are reduced, and the quietness of use is improved. On the other hand, the cooling capacity provided by the condensate atomization device is gradually increased to compensate for the cooling capacity gap caused by the reduction in the operating speed of the outdoor fan, thereby ensuring that the cooling capacity provided by the outdoor fan and the condensate atomization device to the outdoor heat exchanger remains unchanged or basically unchanged.

[0065] The specific steps of controlling the atomization rate of the condensed water atomization device according to the outdoor light intensity can be determined according to actual needs, and the embodiments of the present application are not limited to this. In some examples, proportional-integral-derivative control (PID control for short) can be used. Figure 4 As shown, S80 may include S81 to S83.

[0066] S81: Determine a given temperature of the outdoor heat exchanger according to a current rotation speed of the outdoor fan, a current atomization rate of the condensate atomization device, and a 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 temperature of the outdoor heat exchanger is controlled. A prediction model for the given temperature of the outdoor heat exchanger can be determined in advance, and the input variables of the prediction model include the current speed of the outdoor fan, the current atomization rate of the condensed water atomization device, and the current outdoor ambient temperature, and the output result of the prediction model is the given temperature of the outdoor heat exchanger.

[0068] S82: Determine the control amount of proportional-integral-differential control according to 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 used as the control deviation of the proportional integral differential control. Furthermore, the control deviation can be linearly combined according to the proportion, integration and differentiation to obtain the control amount of the proportional integral differential control.

[0070] S83: Determine the speed adjustment amount of the outdoor fan according to the control amount of the proportional-integral-differential 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 amount of the proportional-integral-differential control, the speed adjustment amount of the outdoor fan can be determined according to the control amount of the proportional-integral-differential control and the outdoor light intensity obtained in real time, based on the predetermined outdoor unit speed adjustment amount calculation model. Here, the input amount of the outdoor unit speed adjustment amount calculation model may include the control amount of the proportional-integral-differential control and the outdoor light intensity, and the output result of the outdoor unit speed adjustment amount calculation model is the speed adjustment amount of the outdoor fan. In this way, the control amount of the proportional-integral-differential control and the outdoor light intensity can be input into the outdoor unit speed adjustment amount calculation model to obtain the speed adjustment amount of the outdoor fan.

[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 of the outdoor fan, 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, exemplarily, before S71 / S81 , the air conditioner control method may include S61 - S62 .

[0074] S61: Acquire historical operation data of the air conditioner 1, the historical operation data including historical temperature data of the outdoor heat exchanger, historical operation speed data of the outdoor fan, historical atomization rate data of the condensate atomization device and historical data of the outdoor ambient temperature.

[0075] S62: Determine a prediction model for a given temperature of the outdoor heat exchanger based on historical operation data of the air conditioner 1 .

[0076] The type of prediction model for a given temperature of an outdoor heat exchanger can be determined according to actual needs, and the embodiments of the present application do not limit this. For example, the historical operation data of the air conditioner 1 can be used as sample data, and model training can be performed based on learning algorithms such as linear regression algorithms, artificial neural network algorithms, or decision tree algorithms to obtain a prediction model for a given temperature of an outdoor heat exchanger such as a linear regression prediction model, an artificial neural network prediction model, or a decision tree prediction model. The input layer of the above prediction model includes the current speed of the outdoor fan, the current atomization rate of the condensate atomization 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] In this way, in S71 / S81, the current speed of the outdoor fan, the current atomization rate of the condensate atomization 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 given temperature of the outdoor heat exchanger is output by the prediction model of the given temperature of the outdoor heat exchanger.

[0078] In the second aspect, an embodiment of the present application provides an air conditioner control device for controlling the above-mentioned air conditioner 1, the air conditioner control device comprising: a light intensity comparison circuit, configured to determine whether the outdoor light intensity is less than or equal to a preset light intensity; an atomization on and off control circuit, configured to control the start-up of a condensation water atomization device 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 the third aspect, an embodiment of the present application provides an air conditioner 1, which has an indoor side and an outdoor side arranged relatively to each other, and includes an outdoor heat exchanger, an outdoor fan, a condensed water atomizing device, a processor 10 and a memory 20.
