The invention discloses an electric cabinet temperature humidity control system and method, and relates to the field of electrical equipment. The system comprises an evaporator, an expansion valve and an expansion valve control device, wherein the expansion valve is arranged between the evaporator and a refrigerant reservoir, the expansion valve control device and the expansion valve are electrically connected for adjusting the openness of the expansion valve, and the evaporator can carry out heat exchange with air inside an electric cabinet. According to the invention, the temperature and the humidity of the electric cabinet can be controlled by use of the evaporator, the temperature inside the electric cabinet can be reduced, hot air inside the electric cabinet can also be condensed, condensed water is discharged out of the electric cabinet, the temperature and the humidity of the electric cabinet are effectively reduced, both the temperature and the humidity are adjusted, and a relative constant-temperature constant-humidity environment is formed in the electric cabinet. Besides, through adjusting the flow of a refrigerant, the humiture control intensity of the electric cabinet can be adjusted.
Description
technical field [0001] The invention relates to the field of electrical equipment, in particular to a temperature and humidity control system and method for an electrical cabinet. Background technique [0002] It is very important to keep the temperature and humidity in the electrical cabinet within a reasonable range to ensure the reliability and life of the electrical cabinet. There are many electrical components distributed in the electrical cabinet. If the temperature in the electrical cabinet is too high, the components will be derated, and the components will be overheated and damaged, and the system will not work normally. If the humidity in the electrical cabinet is too high, the Condensation will appear in the cabinet. On the one hand, various electrical components will be damaged due to electrochemical corrosion, which will affect the reliability and life of the electrical cabinet. ACCIDENT. [0003] At present, most of the electrical cabinets are cooled by air c...
