when the temperature T2-T1 is less than the seventh preset temperature, the air outlet temperature is further lowered, the air outlet position generates condensation if the air conditioner running frequency is kept unchanged or the frequency is increased, the air conditioner running frequency is lowered at intervals, the refrigerating frequency can be effectively lowered, condensation is effectively prevented, and meanwhile the air deflector is controlled to be fixed.
In some embodiments, the fourth preset temperature is 12 ℃, the fifth preset temperature is 14 ℃, the sixth preset temperature is 16 ℃, and the seventh preset temperature is 18 ℃; and/or the presence of a gas in the gas,
the fifth preset time is 60s, the third frequency is 1HZ, the sixth preset time is 180s, and the fourth frequency is 1 HZ.
