[0044] Working principle:

[0045] When the constant temperature and humidity distribution cabinet is installed and used, the third solenoid valve 410 and the first solenoid valve 406 are set to the normally open state through the control panel 202, and the fourth solenoid valve 411 and the second solenoid valve 407 are set to the normally closed state, so that the gas entering the regulating component 4 can successively enter the dehumidification module 414 and the cooling module 412 in the operating state to undergo dehumidification and cooling;

[0046] If the temperature and humidity of the air in the cabinet body 201 detected by the sensor 308 deviate from the set value, and the detection result is fed back to the control panel 202, the control panel 202 analyzes the difference, and sends operation and opening instructions to the corresponding module and the solenoid valve connected to the module, and sends shutdown and closing instructions to other modules and the solenoid valves connected to the modules, so that the air entering the regulating component 4 of the cabinet body 201 can be continuously humidified or dehumidified, and then cooled or heated, until the temperature and humidity of the air circulating in the power distribution cabinet reach the set value;

[0047] The operation of the pump 301 allows the air in the cabinet body 201 to continuously enter the adjustment component 4 from the upper part of the cabinet body 201, and after the adjustment component 4 has adjusted the temperature and humidity, the air is continuously and evenly dispersed from multiple directions at the lower part of the cabinet body 201 and injected back into the cabinet body 201, thereby quickly realizing comprehensive and accurate adjustment of the temperature and humidity in the cabinet body 201.

[0048] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
