And S10, stopping the outdoor unit, if so, entering the step S11, otherwise, entering the step S10.
S11, sending a self-cleaning instruction, enabling the air conditioner to enter self-cleaning, clearing accumulated dust-settling time S, and entering step S5.
In this embodiment, the wind speed information of the air conditioning system is obtained by the wind speed obtaining module at regular time, the wind speed weight parameter F is corrected, the accumulated dust-settling time S = ∑ TF is obtained by calculation according to the timing time T and the corrected wind speed weight parameter F corresponding to the timing time T, whether the self-cleaning instruction setting is performed or not is judged by the relationship S between the accumulated dust-settling time S and the outdoor unit self-cleaning period threshold value U and the geographical location information weight parameter H being greater than or equal to (U/H), the self-cleaning instruction setting is waited for the outdoor unit to be stopped after the self-cleaning instruction setting, the self-cleaning instruction is sent after the outdoor unit is stopped, and the air conditioner enters self-cleaning. According to the embodiment, the self-cleaning time is adjusted through the geographical position information and the wind speed information of the air-conditioning system, and the self-cleaning time of the air conditioner is intelligently decided. Geographical position information can embody the size of the wind-blown sand, and wind speed information can embody the amount of the wind-blown sand scraping the outdoor heat exchanger, and the embodiment further updates the wind speed information at regular time, so that the embodiment can reflect the pollution condition of the heat exchanger of the outdoor unit of the air conditioner more truly, the self-cleaning time interval of the air conditioning system is reasonable, and the condition that the outdoor heat exchanger is polluted more, does not enter self-cleaning or is polluted less and enters self-cleaning is avoided.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
