Referring to fig. 2, an embodiment of the present invention provides an air conditioner fan control method, including:
step S10, obtaining outdoor environment temperature and compressor parameters;
in this embodiment, the electronic device takes an air conditioner as an example, the air conditioner operates according to an instruction of a user, or automatically starts to operate according to a parameter set in advance, and the operating parameter can be adjusted according to an instruction of an environmental condition or a user requirement in an operating process. Of course, the air conditioner can also automatically control the operation of the air conditioner by setting a detection device to detect environmental parameters and user conditions, and automatically setting the operating temperature, the air guide angle and/or the air speed of the air conditioner.
The air conditioner is provided with a temperature detection device, the temperature detection device comprises an outdoor temperature detection device and an indoor temperature detection device, and the outdoor environment temperature detected by the detection device is obtained by detecting the outdoor environment temperature through the temperature detection device arranged outdoors. The outdoor environment temperature detection device can be arranged on the outdoor unit or in the outdoor environment, and then is accessed through the communication connecting line of the outdoor unit, and the outdoor environment temperature is acquired from the outdoor environment temperature detection device through the communication connecting line.
Simultaneously with, before, or after the outdoor ambient temperature is obtained, the air conditioner compressor parameter is obtained, and the compressor parameter can be the rotating speed or frequency of the compressor and the like.
Step S20, determining the corresponding air conditioner outdoor unit fan control duty ratio according to the outdoor environment temperature and the compressor parameter;
after the outdoor environment temperature and the compressor parameter are obtained, determining a corresponding duty ratio according to the outdoor environment temperature and the compressor parameter, for example, determining an outdoor unit fan control duty ratio of an air conditioner according to the outdoor environment temperature, determining an outdoor unit fan control duty ratio of the air conditioner according to the compressor parameter, and averaging the outdoor unit fan control duty ratio and the outdoor unit fan control duty ratio to obtain a final outdoor unit fan control duty ratio of the air conditioner; or different proportional coefficients are taken to obtain the final control duty ratio of the fan of the outdoor unit of the air conditioner through comprehensive calculation according to the outdoor environment temperature and the compressor parameters.

step S21, determining a wind speed interval calculation coefficient corresponding to the outdoor environment temperature as a first calculation coefficient, and determining a wind speed interval calculation coefficient corresponding to the compressor parameter as a second calculation coefficient;
and step S22, calculating the duty ratio of the control of the outdoor unit of the air conditioner according to the first calculation coefficient and the second calculation coefficient. The outdoor environment temperature and the compressor parameter have corresponding duty ratio calculation coefficients, before the duty ratio is calculated, the corresponding calculation coefficients are determined according to the current outdoor environment temperature value and the compressor parameter value, and then the duty ratio is calculated according to the calculation coefficients. The corresponding relation between the outdoor environment temperature value and the compressor parameter value and the calculation coefficient is established in advance and can be established according to actual requirements and experimental experience.
In an embodiment, the calculation coefficients are different due to different operation modes of the air conditioner, before the calculation coefficients are determined, the current operation mode of the air conditioner is determined, the wind speed interval calculation coefficient corresponding to the outdoor environment temperature according to the operation mode is a first calculation coefficient, and the wind speed interval calculation coefficient corresponding to the compressor parameter is determined to be a second calculation coefficient. In different modes, the coefficients for calculating the duty cycle are different, for example, in the cooling mode, the duty cycle is calculated in the following manner: k1 × T4+ K2 × n, in the heating mode, the duty ratio is calculated in the following manner: k3 × T4+ K4 × n, where K1 is a first calculation coefficient in the cooling mode, K2 is a second calculation coefficient in the cooling mode, T4 is the outdoor ambient temperature, and n is the compressor rotation speed; k3 is a first calculation coefficient in the heating mode, and K4 is a second calculation coefficient in the heating mode.

And after the duty ratio of the outdoor fan of the air conditioner is determined, controlling the operation of the outdoor fan of the air conditioner according to the duty ratio.
After the duty ratio of the outdoor fan of the air conditioner is determined, the actual duty ratio of the current outdoor fan of the air conditioner is obtained before adjustment, and the outdoor fan of the air conditioner is adjusted to operate according to the actual duty ratio and the determined duty ratio.
In the actual operation process, the actual duty ratio of the air conditioner is unstable under the condition that the rotating speed of the fan of the air conditioner is unstable. Alternatively, whether the rotating speed of the outdoor fan of the air conditioner is stable is judged by judging the stability of the air volume continuously output by the outdoor fan of the air conditioner. And if the rotating speed of the outdoor fan of the air conditioner is judged to reach the stable state, the outdoor fan of the air conditioner feeds back the actual duty ratio, and the value of the actual duty ratio is detected. Specifically, in order to ensure the accuracy of the actual duty ratio detection, a plurality of values, for example, 8, of the actual duty ratio fed back by the outdoor fan of the air conditioner are detected, and the actual duty ratio fed back by the outdoor fan of the air conditioner is acquired. After acquiring the actual duty cycle of the outdoor fan of the air conditioner, the plurality of values are processed, for example, averaged. And adjusting the operation of the outdoor fan of the air conditioner according to the average value and the determined duty ratio.
The embodiment determines the duty ratio of the outdoor fan according to the outdoor environment temperature and the compressor parameter by acquiring the outdoor environment temperature and the compressor parameter outside the air conditioner acting space, and then controls the operation of the outdoor fan of the air conditioner according to the duty ratio. Different stepless speed change modes are provided, the manufacturing cost of the air conditioner is reduced, and the flexibility of the air speed control of the outdoor fan is improved.
In an embodiment of the present invention, referring to fig. 4, before the step of determining that the wind speed interval calculation coefficient corresponding to the outdoor environment temperature is a first calculation coefficient and the step of determining that the wind speed interval calculation coefficient corresponding to the compressor parameter is a second calculation coefficient, the method further includes:

The linkage interval of the wind speed compressor is a preset interval and is an outdoor environment temperature and compressor linkage interval. The outdoor environment temperature is divided into different temperature intervals, for example, the temperature of 1-10 ℃ is an interval A, the temperature of 11-20 ℃ is an interval B, the temperature of 21-25 ℃ is an interval C, and the temperature of 26-30 ℃ is an interval D. According to different temperature intervals of outdoor environment temperature, corresponding to different air speed intervals of the outdoor unit of the air conditioner, for example, the D interval corresponds to an ultrahigh wind interval, and corresponding relations are set according to requirements and actual conditions. Of course, the air conditioner has different operation modes, and the temperature interval may also be different from the interval of the outdoor unit of the air conditioner.
