Specifically, in the dehumidification mode, the airflow entering the air duct a from the first air outlet e exchanges heat with the first heat exchanger 30 at first, and the first heat exchanger 30 is an evaporator, so that the airflow is cooled and dehumidified after flowing through the first heat exchanger 30 to generate condensed water to form a cold airflow, and the cold airflow flows to the second heat exchanger 40 and is heated by the second heat exchanger 40, so that the temperature of the airflow discharged from the second air outlet f is not reduced, and the purpose of cooling and dehumidifying is achieved.

Specifically, the indoor ambient temperature may be acquired from a temperature sensor. It should be understood that the temperature sensor may be integrated on the air conditioner 1 or may be placed indoors, i.e. separate from the air conditioner. If the temperature sensor is separately provided from the air conditioner 1, the temperature sensor may communicate with the controller in the air conditioner 1 by wire or wirelessly, for example, a fourth temperature sensor 105 is provided at the air inlet d, and the fourth temperature sensor 105 is used to obtain the indoor ambient temperature T0 in the cooling mode.

Specifically, the indoor ambient temperature may be acquired from a temperature sensor. It should be understood that the temperature sensor may be integrated on the air conditioner 1 or may be placed indoors, i.e. separate from the air conditioner. If the temperature sensor is provided separately from the air conditioner 1, the temperature sensor may communicate with the controller in the air conditioner 1 by wire or wirelessly.

If T0 is greater than T, the compressor is controlled to operate at the second target frequency, the first wind wheel 2011 and the second wind wheel 2021 rotate, and the first fan assembly 201 is controlled to rotate so that an included angle between a rotation center line of the first wind wheel 2011 and a plane where the second air inlet d2 is located is not less than 90 ° (e.g., 90 °), thereby preventing the first fan assembly 201 from blowing air towards the second air inlet d2 and affecting the refrigeration effect.
