In the present application, the air conditioner performs a refrigerating cycle of the indoor air conditioner by using a compressor, a condenser, an expansion valve, and an indoor heat exchanger. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The indoor heat exchanger may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. In the whole cycle, the indoor air conditioner can adjust the temperature of the indoor space. The outdoor unit of the indoor air conditioner refers to a portion of the refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the indoor air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an indoor heat exchanger. When the indoor heat exchanger is used as a condenser, the indoor air conditioner is used as a heater for a heating mode, and when the indoor heat exchanger is used as an indoor heat exchanger, the indoor air conditioner is used as a cooler for a cooling mode.

Whether to enter the fresh air mode or not can be selected according to a user so as to start the fresh air fan.
In some embodiments, the first preset time is 4-6 s. The air conditioner comprises an indoor air conditioner and an air conditioner external machine which are connected with each other, after the indoor air conditioner is started and runs in a wind mode, the air conditioner detects the temperature of external air in a first preset time, and when the temperature is lower than a preset value or higher than the preset value, the controller controls the fresh air fan to continue running at a first fresh air rotating speed or stop running of the fresh air fan. The first preset time is used for detecting the temperature of the external air by the air conditioner, so that the air conditioner can be ensured to accurately operate.
In some embodiments, the first preset time is 5S.
In some embodiments, the fresh air fan operates at a second fresh air rotational speed when the air deflection 200 is in a semi-open state. That is, after the indoor air conditioner is turned on and runs in the wind blowing mode, the wind deflector 200 is slowly turned over, the rotation speed of the fresh air fan is gradually increased, when the first preset time is reached, the wind deflector 200 is in a half-open state, and the rotation speed of the fresh air fan is increased to the second fresh air rotation speed.
In some embodiments, after the air deflector 200 reaches the half-open state, the air deflector 200 continues to slowly turn over to open the fresh air port 400, while the fresh air fan continues to increase the rotational speed. When the wind deflector 200 completely opens the fresh air inlet 400, the fresh air fan operates at a third fresh air rotational speed. The opening and closing amplitude of the air deflector 200 corresponds to the rotating speed of the fresh air fan.

In some embodiments, after the fresh air fan operates at the third fresh air rotation speed to reach the preset condition, the controller controls the driving piece to drive the air deflector 200 to slowly turn over from the fully opened state to the half opened state, and simultaneously the rotation speed of the fresh air fan is reduced, and when the air deflector 200 is in the half opened state, the fresh air fan operates at the second fresh air rotation speed. The wind deflector 200 continues to overturn and the rotation speed of the fresh air fan continues to drop, and when the wind deflector 200 completely closes the fresh air port 400, the fresh air fan is in a closed state.
In some embodiments, after the fresh air fan is operated at the third fresh air rotational speed to reach the preset condition, the fresh air fan is operated at the first fresh air rotational speed when the air deflector 200 is turned to the half-open state.
In some embodiments, the preset condition is one of a user turning off the indoor air conditioner, a carbon dioxide concentration <1200ppm, a temperature of 18-25 ℃ and an operating time of a second preset time. The second preset time is set according to the user demand.
In some embodiments, the preset conditions are preferably carbon dioxide concentrations up to 800ppm or temperatures up to 20 ℃.
In some embodiments, the air deflection 200 is also used to open and close the air outlet 300.
In some embodiments, after the fresh air fan is operated at the third fresh air rotation speed to reach the preset condition, the rotation speed of the air conditioner fan is gradually reduced in the process that the air deflector 200 is gradually turned over to close the fresh air port 400. When the wind deflector 200 closes the fresh air port 400, the air conditioner fan is turned off.
