The humidity control apparatus 130 includes a humidifying unit 132 and a water tank 133, the humidifying unit 132 is disposed inside the water tank 133, and the humidifying unit 132 is configured to atomize and/or vaporize water in the water tank to humidify gas above a liquid level in the water tank. The humidity conditioning apparatus 130 includes, but is not limited to, an ultrasonic nebulizer and a steam humidifier. The ultrasonic atomizer and the steam humidifier have the advantages of strong humidifying capacity, adjustable humidifying quantity and the like.
In one embodiment, the humidity control device 130 employs an isenthalpic humidity control process, which can adjust the relative humidity between 65% and 95%. In another embodiment, when the humidity setting value is less than or equal to 65%, the environmental control system for dehydration and humidity reduction bacteriostasis can perform humidification by using a pipeline humidification mode. Thus, the problems of condensation, overshoot and the like under the low humidity condition can be avoided.

The operation modes are different, and the oxygen content in the airtight enclosure equipment is different. The pressurized gas source feeds nitrogen into the gas-tight containment to reduce the oxygen content. The humidity sensor detects the humidity of the gas in the airtight enclosure equipment 150 in real time and uploads the detected humidity to the main control module 140, and the main control module 140 controls the on-off angle and frequency of the first electromagnetic valve 131 according to the set humidity information so as to adjust the humidity of the gas in the airtight enclosure equipment 150.

Therefore, the top of the airtight enclosure equipment is designed into a structure with high middle and low periphery, and when liquid drops are formed, the liquid drops can be left along the side wall, so that the situation that the liquid drops directly fall on a collection is avoided.
In one embodiment, the humidity conditioning apparatus 130 is connected to the air-tight enclosure 150 by a pipe, wherein the pipe includes a drain switch for draining condensed water in the pipe. The drain switch may be a solenoid valve, which is electrically connected to the main control module 140 and receives the command of the main control module 140 to drain water at regular time. The drainage switch can also be a manual switch, and the drainage operation is carried out manually.
