Comprehensive application of cooling dehumidification and rotary dehumidification in an underground hydropower plant

Analyses the causes of the humidity and condensation problems existing in an underground hydropower plant. Finds that the main reason is not high relative humidity, but the condensation of precooled water vapor in air. According to the actual operation condition of the plant, suggests the comprehensive solution of cooling dehumidification and rotary dehumidification application. Expounds the selection calculation of dehumidification equipment, improving measures for the air system and central control system and operation scheme of dehumidification system.
