In the prior art, an air conditioner may include an indoor unit and an outdoor unit, the indoor unit includes a heat exchanger, the outdoor unit includes a compressor and a heat exchanger, the heat exchanger of the indoor unit and the compressor and heat exchanger of the outdoor unit pass through The pipelines are connected to form a circulation loop, and there is a refrigerant (such as Freon) in the circulation loop. When the air conditioner is in the cooling mode, the heat exchanger of the outdoor unit acts as a condenser, and the heat exchanger of the indoor unit acts as an evaporator, and the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant. At this time, the refrigerant is in a state that is easy to liquefy. Then the refrigerant flows through the condenser to dissipate heat and becomes a liquid refrigerant at room temperature and high pressure; when the liquid refrigerant enters the evaporator, the space suddenly increases, the pressure decreases, and the liquid refrigerant vaporizes into a gaseous low-temperature refrigerant, thereby absorbing a large amount of heat, making the evaporator When it gets colder, the air in the room enters the indoor unit and flows through the evaporator under the action of the fan, and then becomes cold air when it flows out of the indoor unit, thereby reducing the indoor temperature.

Conversely, when the air conditioner is in the heating mode, the refrigerant circulates in the opposite direction to that in the cooling mode. At this time, the heat exchanger of the indoor unit acts as a condenser, and the heat exchanger of the outdoor unit acts as an evaporator, and the refrigerant flows through the room. The heat exchanger of the machine dissipates a large amount of heat, which makes the evaporator hot, and the indoor air enters the indoor unit and flows through the evaporator under the action of the fan, and then becomes hot air when it flows out of the indoor unit, thus making the indoor The temperature rises.

Exemplarily, the first preset humidity threshold may be a relative humidity value, and the first preset humidity threshold may be 0.4.

It should be noted that, in some other embodiments, the first humidity value detected by the first humidity sensor 3 can be directly input into the power supply controller 5, and the power supply controller 5 can compare the first humidity value with the first humidity value through a software algorithm. The preset humidity threshold is compared, and then the ultrasonic nebulizer 205 is controlled to work or not to work according to the comparison result, which can also be applied.

In addition, the power supply controller 5 can also compare the second humidity value with the second preset humidity threshold (for example, the second preset humidity threshold can be 0.6) through a software algorithm, and then control the vibrating atomizer according to the comparison result 2053, and then adjust the humidity of the airflow at the air outlet 102.
