In step S101, the air conditioner determines an operation mode thereof, and the operation mode includes a humidification mode and a dehumidification mode.
There are many methods for acquiring the indoor humidity, for example, a humidity sensor is provided in the room, the indoor humidity is acquired by the humidity sensor, or the indoor humidity is acquired by weather forecast.
Step S102, under the condition that the air conditioner operates in a humidifying mode, if the indoor humidity is larger than a first threshold value, the air conditioner reduces the rotating speed of a moisture absorption fan; and if the indoor humidity is smaller than the first threshold value, the rotating speed of the moisture absorption fan is increased. And/or the presence of a gas in the gas,

In the humidification mode, the indoor humidity is smaller than a first threshold value, which indicates that the smaller the indoor humidity is, the rotating speed of the moisture absorption fan is increased, the moisture absorption fan in unit time can drive more unheated air to flow through the moisture absorption material, and the moisture absorption material absorbs more moisture from the unheated air, so that the heated air can absorb more moisture and is discharged to the indoor when flowing through the moisture absorption material, and rapid humidification is realized; indoor humidity is greater than first threshold value, it is great to explain indoor humidity, easy humidification, the rotational speed of moisture absorption fan reduces, the moisture absorption fan can drive less unheated air of lower volume and flow through hygroscopic material in the unit interval, hygroscopic material absorbs less moisture in the unheated air, thereby can absorb less moisture and discharge to indoor when the hygroscopic material is flowed through to the air of heating, because indoor humidity is great, neither can excessively prolong dehumidification time, still realize accurate humidification, and can reduce the humidification energy consumption of air conditioner.
In the dehumidification mode, the indoor humidity is larger than the second threshold value, which indicates that the indoor humidity is larger, the rotating speed of the moisture absorption fan is increased, the moisture absorption fan can drive more unheated air to flow through the moisture absorption material in unit time, and the moisture absorption material absorbs more moisture from the unheated air, so that the heated air can absorb more moisture and is discharged to the outside when flowing through the moisture absorption material, and rapid dehumidification is realized; indoor humidity is less than the second threshold value, it is less to explain indoor humidity, dehumidify more easily, the rotational speed of moisture absorption fan reduces, the moisture absorption fan can drive less unheated air of less volume and flow through hygroscopic material in the unit interval, hygroscopic material absorbs less volume moisture in the unheated air, thereby can absorb less volume moisture and discharge to outdoor when the hygroscopic material is flowed through to the air of heating, because indoor humidity is less, neither can excessively prolong dehumidification time, still realize accurate dehumidification, and can reduce the dehumidification energy consumption of air conditioner.
Under the humidification mode and the dehumidification mode, the rotating speed of the moisture absorption fan is determined according to the size relationship between the indoor humidity and the first threshold value and the size relationship between the indoor humidity and the second threshold value, and the humidity adjustment energy consumption of the air conditioner can be reduced on the premise that the humidity adjustment speed requirement of a user is met.
In step S101, the indoor humidity can be further represented by an operating environment parameter of the air conditioner, where the operating environment parameter may be an indoor condensed water amount, an evaporator wind resistance, a current air intake of the indoor unit, a compressor frequency, and the like.
