Referring to fig. 5, a third embodiment of the method for controlling an air conditioner according to the present invention is based on the first or second embodiment, before the step S30, further comprising:
and step S40, when the temperature difference between the temperature of the indoor heat exchanger and the preset temperature is larger than the preset temperature, acquiring the current state of the air conditioner.
And step S50, when the current state of the air conditioner is the running state, reducing the frequency of the compressor of the air conditioner.
In air conditioner's air duct assembly cleaning process, the air conditioner can wash under the standby state, also can wash under the running state, when wasing under the running state, in order to prevent that the current operational mode of air conditioner from influencing the washing, if the compressor frequency is too high, and when operation refrigeration mode, during washing indoor heat exchanger, water can freeze, and then can't wash, if when the mode is heated in the operation, during washing indoor heat exchanger, water can evaporate into the gaseous state, and then influence the cleaning performance. In addition, when the frequency of the compressor is too high, the heat exchanger is washed by water, so that the operation of the compressor is influenced, and therefore, when the air conditioner is in the current operation state, the frequency of the compressor is reduced, so that the air conditioner in the operation state is prevented from influencing the cleaning of the heat exchanger.
In this embodiment, when control belt cleaning device washs the wind channel subassembly, if the air conditioner is in running state, then through the mode that reduces compressor frequency, the effect that leads to the air conditioner regulation of air conditioner too low when avoiding indoor heat exchanger to frost and wash among the cleaning process, ensures the operation safety of air conditioner.
Referring to fig. 6, a fourth embodiment of the method for controlling an air conditioner according to the present invention is based on any one of the first to third embodiments, and further includes, after step S40:
and step S60, when the current state of the air conditioner is the running state, judging whether the frequency of the compressor is greater than a preset frequency.
When the compressor frequency is greater than the preset frequency, step S50 is executed, that is, the compressor frequency of the air conditioner is decreased.
Before the step of reducing the frequency of the compressor, judging whether the frequency of the compressor is greater than a preset frequency; when the frequency of the compressor is greater than the preset frequency, the operation requirement on the air conditioner when the air duct assembly of the air conditioner is cleaned is not met by the frequency of the compressor of the air conditioner, so that the frequency of the compressor of the air conditioner needs to be reduced.
And step S70, when the frequency of the compressor is less than or equal to the preset frequency, judging whether the rotating speed of the fan of the air conditioner is greater than the preset rotating speed.
And step S80, when the rotating speed of the fan is greater than the preset rotating speed, reducing the rotating speed of the fan.
When the frequency of the compressor is less than or equal to the preset frequency, the air conditioner is kept to operate at the current frequency of the compressor, in addition, in the cleaning process, if the wind speed is too high, the cleaned water can be blown into a room along with the wind, or cleaned impurities can be blown into an air duct to pollute the indoor environment, therefore, after the frequency of the compressor is reduced, the current fan rotating speed of the air conditioner is judged in order to adapt to the reduced frequency of the compressor, and when the current rotating speed of the fan is greater than the preset rotating speed, the rotating speed of the fan is reduced; and when the current rotating speed of the fan is less than or equal to the preset rotating speed, keeping the air conditioner to operate the fan at the current rotating speed.
In this embodiment, the preset frequency of the compressor and the preset rotating speed of the fan are obtained through multiple tests, and are suitable for parameter values when cleaning an air duct assembly of an indoor unit of an air conditioner, and the corresponding numerical values of air conditioners of different models are different. When the compressor frequency and the fan speed are reduced, the compressor frequency may be reduced to the preset frequency and the fan speed may be reduced to the preset speed, or the compressor frequency may be reduced to other fixed frequencies and the fan speed may be reduced to other fixed speeds, but the values of the other fixed frequencies and the other fixed speeds are preferably lower than the preset frequency and the preset speed, so as to ensure that the air conditioner is cleaned safely and has the lowest influence on indoor air conditioning.
Further, when the air conditioner is in the operation mode, an air duct assembly of an indoor unit of the air conditioner is cleaned, whether the current compressor frequency is larger than a preset frequency is judged firstly, if the current compressor frequency is too large, the operation mode of the air conditioner is adjusted to the preset mode, and under the preset mode, the compressor frequency and the fan rotating speed of the air conditioner meet the requirements for the compressor frequency and the fan rotating speed during washing. For example, the operation mode of the current air conditioner is a refrigeration mode, when the air conditioner cleans the air duct assembly, the operation mode of the air conditioner is switched to an intermediate refrigeration mode, under the refrigeration mode, the frequency of the compressor is 85, the frequency of the compressor corresponding to the intermediate refrigeration mode is 37, and the air speed is an automatic mode under the intermediate refrigeration mode, namely, the frequency of the compressor is correspondingly changed along with the frequency of the compressor, the frequency of the compressor is reduced, the capacity output is relatively reduced, the air volume is also reduced, and the influence of temperature and humidity fluctuation on the indoor temperature and humidity is reduced when the air duct assembly is washed with water.
Further, after the step of reducing the frequency of the compressor, the method further comprises the following steps: judging whether the current rotating speed of the air conditioner fan is greater than the preset fan rotating speed or not; and judging whether the rotating speed of the fan of the air conditioner is greater than a preset rotating speed or not, and reducing the rotating speed of the fan when the current rotating speed is greater than the preset rotating speed so as to adapt to the reduced compressor frequency of the compressor.
In addition, when adjusting the operating parameter of air conditioner, including reducing compressor frequency, reducing fan rotational speed and switching air conditioner's operational mode, obtain the current operating parameter of air conditioner, and store operating parameter for when the air conditioner stops to wash during the wind channel subassembly, control the air conditioner operates according to the operating parameter that stores, resumes the original work function of air conditioner.
This embodiment is at the in-process of washing air conditioner's air duct assembly, and when the air conditioner was in the running state, through the mode that reduces compressor frequency and fan rotational speed, avoid current running state to influence the washing of heat exchanger, ensure air conditioner cleaning performance.
Referring to fig. 7, a fifth embodiment of the method for controlling an air conditioner according to the present invention is based on any one of the first to fourth embodiments, before step S20, the method further includes:
and step S90, when the current state of the air conditioner is the running state, acquiring the current running mode of the air conditioner.
And S100, when the current operation mode of the air conditioner is a cooling mode, switching the current operation mode of the air conditioner to an air supply mode.
In the process of cleaning the air duct assembly of the indoor unit of the air conditioner, if the air conditioner runs in a refrigeration mode, water is easy to freeze and frost on the air duct assembly, when the cleaning effect is to be realized, after the air duct assembly is frozen and frost is formed, the mode of heating needs to be switched to melt the ice and frost, and the mode of heating needs to be switched to generate noise pollution, so that in order to prevent the water from freezing and frost on the heat exchanger in the water washing process, when the current running mode of the air conditioner is the refrigeration mode, the air conditioner is switched to an air supply mode and then cleaned.
It can be understood that, in order to prevent the operation of the air conditioner from affecting the water washing of the heat exchanger, after the air conditioner is controlled to switch to the air supply mode, the step of reducing the frequency of the compressor is performed to ensure that the air conditioner is washed in the optimal washing state without affecting the adjusting effect of the air conditioner.
In the embodiment, when the current operation mode of the air conditioner is the refrigeration mode, the air conditioner is controlled to be switched to the air supply mode, so that the air duct assembly of the indoor unit is prevented from icing and frosting when the air conditioner is washed, the heat exchanger of the air duct assembly is guaranteed to be washed in the best washing state, and the washing effect of the air duct assembly is improved.
