Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
Fig. 1 is a method for controlling an operation of an air conditioner according to an embodiment of the present disclosure, the method including:
and step S11, acquiring the input voltage of the air conditioner and the outdoor environment temperature.
And step S12, under the condition that the input voltage and the outdoor environment temperature meet the frequency modulation condition, adjusting the running frequency of the compressor of the air conditioner according to the input voltage and the outdoor environment temperature.
Wherein, the input voltage is the input voltage of the air conditioner complete machine. Optionally, the outdoor ambient temperature is obtained by a temperature detecting device disposed in the outdoor unit of the air conditioner. Optionally, the outdoor ambient temperature is detected by an external temperature detection device, and the air conditioner communicates with the external temperature detection device to obtain the outdoor ambient temperature.
In the embodiment, whether the operation frequency of the compressor needs to be adjusted is determined according to the input voltage and the outdoor environment temperature, and in the process of adjusting the operation frequency of the compressor, the adjustment quantity of the operation frequency is determined by integrating the input voltage and the outdoor environment temperature, so that the operation pressure of the compressor is properly reduced according to the current operation environment, the compressor is prevented from being stopped, and meanwhile, the operation efficiency of the compressor is improved.
Fig. 2 is a method for controlling an operation of an air conditioner according to an embodiment of the present disclosure, the method including:
and step S11, acquiring the input voltage of the air conditioner and the outdoor environment temperature.
And step S22, when the outdoor environment is greater than the temperature threshold and the input voltage is less than the voltage threshold, adjusting the operating frequency of the compressor of the air conditioner according to the input voltage and the outdoor environment temperature.
Wherein, the condition that input voltage and outdoor ambient temperature satisfy the frequency modulation condition includes: the outdoor environment is greater than a temperature threshold and the input voltage is less than a voltage threshold.
The input voltage and the outdoor ambient temperature are important factors affecting the operation of the air conditioner compressor. When the outdoor environment temperature is greater than the temperature threshold value, the air conditioner operates in a cooling mode. Especially for suburb and rural areas, the outdoor temperature is too high in summer, and a large number of users start the air conditioner refrigeration mode at the same time, so that the voltage of a power transmission main circuit is unstable, and the condition of undervoltage occurs. At this time, if the operation frequency of the air conditioner compressor is not adjusted in time, the compressor stops working due to the fact that the air speed of the air conditioner outdoor fan is reduced and heat dissipation is not timely.
The temperature threshold and the voltage threshold are temperature values and voltage values which are obtained by performing a plurality of tests before the air conditioner leaves a factory and ensure the normal operation of the compressor. When the outdoor environment is greater than the temperature threshold and the input voltage is less than the voltage threshold, the compressor is at risk of stopping operation. If the processing is not timely carried out, the compressor stops working, so that the air conditioner cannot refrigerate, and the user experience is reduced.
In the embodiment, whether the operation frequency of the compressor needs to be adjusted is determined according to the input voltage, the outdoor environment temperature and the corresponding threshold, and in the process of adjusting the operation frequency of the compressor, the adjustment quantity of the operation frequency is determined by integrating the input voltage and the outdoor environment temperature, so that the operation pressure of the compressor is properly reduced according to the current operation environment, the compressor is prevented from being stopped, and meanwhile, the operation efficiency of the compressor is improved.

and step S221, determining the rotating speed of the outdoor fan according to the input voltage.
And step S222, determining an operation frequency correction value according to the rotating speed of the outdoor fan, the outdoor environment temperature and the input voltage.
And step S223, adjusting the operating frequency of the compressor according to the operating frequency correction value.
In some embodiments, the outdoor fan speed is determined according to the following equation:
R＝a*V2
wherein R is the rotating speed of the outdoor fan; v is the input voltage; a is a proportionality coefficient.
In the embodiment of the disclosure, the input voltage is an influence factor of the rotating speed of the outdoor fan. The higher the input voltage is, the higher the rotating speed of the outdoor fan is, the lower the input voltage is, and the rotating speed of the outdoor fan is reduced.
In some embodiments, the operating frequency correction value is determined according to the following equation:
Δf＝αR+βT+γV
wherein R is the rotating speed of the outdoor fan; t is the outdoor ambient temperature; v is the input voltage; alpha, beta and gamma are running frequency adjusting coefficients.
In the embodiment of the disclosure, the input voltage and the outdoor ambient temperature are important factors for determining the corrected value of the operating frequency.

The higher the outdoor ambient temperature, the higher the risk of the compressor stopping, the larger the operating frequency correction value.
In the embodiment, the rotating speed of the outdoor fan is determined according to the input voltage, and the operating frequency correction value is further determined according to the rotating speed of the outdoor fan, the outdoor environment temperature and the input voltage so as to adjust the adjustment quantity of the operating frequency of the compressor, so that the accuracy of adjusting the operating frequency of the compressor is improved, and the effectiveness of avoiding the compressor from stopping is improved.

And S2233, adjusting the running frequency of the compressor according to the target running frequency.
Wherein there is a minimum rated operating frequency and a maximum rated operating frequency for the compressor. The rated operating frequency is different according to the type and the refrigerating capacity of the compressor. For an inverter compressor, the compressor is operated at a frequency between the minimum rated operating frequency and the maximum rated operating frequency during operation. In the embodiment of the disclosure, when adjusting the operating frequency of the compressor, the operating frequency should be ensured to be higher than the minimum rated operating frequency.
In the embodiment, the target operation frequency is determined by integrating the operation frequency, the rated operation frequency and the operation frequency correction value, so that the effective and safe operation of the compressor is ensured.
