Note that, the humidity referred to in this embodiment is relative humidity.
In this embodiment, the humidity in the cabinet 10 is detected by a humidity sensor in the cabinet.
The range of the first humidity value is 80-90%, and the range of the second humidity value is 40-70%; the first humidity value and the second humidity value can be set according to actual use requirements.
In this embodiment, the humidity in the cabinet 10 is reduced by the dehumidifying device 40.
In this embodiment, the dehumidifying device 40 independently controls dehumidification based on the humidity in the cabinet 10, and selectively opens or closes the dehumidifying device 40, which is beneficial to saving energy and prolonging the service life of the dehumidifying device 40.
In the present embodiment, the first humidity value is set to 85% and the second humidity value is set to 50%.
The specific control method is that the humidity in the cabinet 10 is detected, when the humidity in the cabinet 10 is higher than 85%, the dehumidifying device 40 is opened, and the humidity in the cabinet 10 is reduced by using the dehumidifying device; after the dehumidifying device 40 is opened, the humidity in the cabinet 10 is continuously detected, and if the humidity in the cabinet 10 is reduced to 50%, the dehumidifying device 40 is closed.
In another embodiment, the humidity inside the cabinet 10 may also be reduced by the ventilation device, and the control method includes: detecting the humidity in the cabinet body 10 and the ambient humidity outside the cabinet body 10, and opening the opening and closing portion 30 when the humidity in the cabinet body 10 is higher than a first humidity value and the ambient humidity is lower than a third humidity value; when the humidity in the cabinet 10 is lower than a second humidity value, the opening and closing portion 30 is closed, and the second humidity value is smaller than the first humidity value.
The range of the third humidity value is 0-75%; the third humidity value can be set according to actual use requirements.
In this embodiment, detect through humidity transducer in the cabinet humidity in the cabinet body 10 detects through humidity transducer outside the cabinet the outside humidity of the cabinet body 10.
Utilize ventilation unit to reduce during the humidity in the cabinet body 10, need satisfy the less condition of ambient humidity, when ambient humidity is less and the humidity is great in the cabinet body 10, through opening the portion 30 that opens and shuts, open air inlet 21 and gas vent 22 and produce the air convection, the air in the cabinet body 10 exchanges with the air outside the cabinet body 10 to reach the mesh that reduces the internal air humidity of cabinet.
In this embodiment, the control method further includes: after the opening and closing part 30 is opened, detecting the humidity in the cabinet body 10, when the humidity in the cabinet body 10 is higher than a fourth humidity value, opening the air inlet assembly 23 and the air outlet assembly 24, generating an airflow passing through the air inlet 21 along the direction from the outside of the cabinet body 10 to the inside of the cabinet body 10 by using the air inlet assembly 23, and generating an airflow passing through the air outlet 22 along the direction from the inside of the cabinet body 10 to the outside of the cabinet body 10 by using the air outlet assembly 24, wherein the fourth humidity value is larger than the first humidity value; when the humidity in the cabinet 10 is lower than a fifth humidity value, the air inlet assembly 23 and the air outlet assembly 24 are closed, and the fifth humidity value is lower than the first humidity value and higher than the second humidity value.
The difference range of the fourth humidity value and the first humidity value is 0-10%, and the difference range of the fifth humidity value and the second humidity value is 0-10%; the fourth humidity value and the fifth humidity value can be set according to actual use requirements.
In the present embodiment, the first humidity value is set to 85%, the second humidity value is set to 50%, the third humidity value is set to 55%, the fourth humidity value is set to 90%, and the fifth humidity value is set to 55%.
The specific control method comprises the steps of detecting the humidity in the cabinet body 10 and the ambient humidity outside the cabinet body 10, opening the opening and closing portion 30 when the humidity in the cabinet body 10 is higher than 85% and the ambient humidity is lower than 55%, opening the air inlet 21 and the air outlet 22 to exchange air so as to reduce the humidity in the cabinet body 10, opening the opening and closing portion 30, enabling the humidity in the cabinet body 10 to still rise to 90%, opening the air inlet assembly 23 and the air outlet assembly 24, accelerating air flow, accelerating the reduction of the humidity in the cabinet body 10 until the humidity in the cabinet body 10 drops to 55%, closing the air inlet assembly 23 and the air outlet assembly 24, continuously detecting the humidity in the cabinet body 10 until the humidity in the cabinet body 10 drops to 50%, and closing the opening and closing portion 30.
Through the coupling control of inside humidity and outside environment humidity, be favorable to more carrying out the anti-condensation control of regulator cubicle because of the environment system is fit.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
