Whether the water level in putting reaches preset water level；If it is determined that the water level stated in water storage device reaches preset water level, then early warning is sent
Prompting.
Wherein, preset water level can be demarcated according to actual conditions, for example, preset water level can be η H, wherein, η is
Configurable parameter.For example, as η=90%, if the water level in water level h in water storage device >=90%H, i.e. water storage device reaches
To the 90% of water storage device height, then dehumidification system sends early warning.
S3, judges whether to close dehumidification system according to the humidity interval of present air.
According to one embodiment of present invention, in this step, if default desired air humidity value is more than or equal to
The interval higher limit of the humidity of present air, then close dehumidification system.
Wherein, default desired air humidity value can be demarcated according to actual conditions.
Specifically, by default desired air in the interval higher limit of the humidity of the present air of acquisition and dehumidification system
Humidity value is compared, if having reached default desired air humidity value, closes dehumidification system.For example, default preferable empty
Air humidity angle value is b%, and the humidity interval of the present air of acquisition is ai-1%-ai%, if ai% ＜ b%, then it represents that present air
Humidity meet default desired air humidity value, now need close dehumidification system.
In summary, the control method of dehumidification system according to embodiments of the present invention, every a sampling period detection storage
Water level in water installations, the water level rate of climb in water storage device, and root are obtained according to the water level in the water storage device detected
The humidity for obtaining present air according to the water level rate of climb is interval, and judges whether that closing is removed according to the humidity interval of present air
Wet system, is automatically adjusted so as to realize to air humidity, air humidity is reached desired air humidity, improves Consumer's Experience.
