The preset frequency can be specifically 0, when the target frequency of the compressor is 0, the function of fresh air can be realized, the circulating fan and the outdoor fan rotate reversely at the moment, and the outdoor fresh air is pumped to the indoor space by utilizing the power of the reverse rotation of the fan to achieve the function of fresh air exchange. When the frequency F of the compressor meets the condition that F is larger than 0, the unit has the refrigerating or heating requirement, if the air duct fan and/or the outdoor unit fan of the air conditioner are in a reverse rotation state at the moment, the heat exchange efficiency of the outdoor condenser is influenced if the air duct fan and/or the outdoor unit fan of the air conditioner are not closed, and meanwhile, the outdoor unit fan rotates forwards. And if the frequency of the compressor does not meet the condition that F is larger than 0, continuing to reversely rotate the fan of the air duct and/or the fan of the outdoor unit.
For example, during the period of the fresh air function setting of "1", whether the frequency F of the compressor meets F > 0 is judged, if the frequency F meets F > 0, the air duct fan is closed, if the frequency F of the compressor does not meet F > 0, the system defaults that the unit has no refrigeration or heating requirement, namely, the unit is in a shutdown state, the fresh air function setting of "1" is maintained, and fresh air is continuously provided for the indoor.

And S180, if the temperature of the outdoor heat exchanger is judged to be greater than or equal to the fifth temperature, controlling the air duct fan and/or the fan of the outdoor unit to reversely rotate so as to introduce the waste heat of the condenser of the outdoor unit into the room.
Because the outdoor side is the high pressure side in the defrosting or oil return process of heating, the condenser blows hot air, at this moment, the hot air after outdoor heat exchange is guided to the indoor side by controlling the reverse rotation of the outdoor unit fan and/or the reverse rotation of the air channel fan in the air channel, and the purposes of indoor continuous heating and heat recovery in the defrosting stage are also achieved, so that the use efficiency of the air conditioner is greatly improved, and the comfort experience of a user is improved. Optionally, the fan for controlling the air duct fan and/or the outdoor unit to reversely rotate during heating and defrosting may be set as a "continuous heating" function, and when the temperature of the outdoor heat exchanger is equal to or higher than a fifth temperature, the continuous heating function is set to "1", which indicates that the function is turned on.
For example, when T is during defrosting in heating modeOuter tubeSatisfy TOuter tubeAnd t5, the outdoor unit fan and the air duct fan are reversely rotated with the continuous heating function of '1', and the waste heat utilization air duct fan at the condensation side is introduced into the indoor side during defrosting, so that the purposes of continuous heating and waste heat recovery are realized, the use efficiency of the air conditioner is greatly improved, and the comfort experience of a user is improved.
