A DEHUMIDIFIER FOR UNDERGROUND AIR

摘要

PURPOSE: A dehumidifier for underground air is provided to reduce moisture included in the underground air by contacting the moisture included in the underground air with a dehumidifying net. CONSTITUTION: A dehumidifier for underground air comprises an outer housing, middle and inner housing(40,50), and a dehumidifying net(60). The outer housing is installed between an underground air intake pipe and an underground air discharge pipe(14). The middle housing has an inlet hole(42) and an air outlet hole(44). The underground air sucked in the outer housing flows into the air inlet hole. The inner housing has an air injecting hole(52) and an air ejecting hole(54). The underground air flowing through the air inlet hole is injected into the air injecting hole. The air ejecting hole ejects the underground air to the middle housing. The dehumidifying net is charged in one among inner spaces of the outer, middle, and inner housings. The dehumidifying net dehumidifies the underground air discharged to the air ejecting hole.
