Description

{DEHUMIDIFIER FOR REDUCTION OF OPERATIONAL COSTS}

The present invention relates to a dehumidifying apparatus, and more particularly, to a dehumidifying apparatus for operation cost saving for controlling the humidity of a ship painting factory.

Dehumidifiers are used to control the humidity during shipbuilding process. Generally, since the dehumidifier is used for relative humidity control, the humidity to be discharged is low, but the temperature is relatively high. However, in the actual workplace, the work environment of the operator is very important as well as the relative humidity control. Therefore, it is preferred to supply the dehumidified air as low as possible, and some equipment uses the aftercooler before discharge to cool the air.

However, if the after-cooler is used separately during the dehumidification in the summer, there is a problem that the operation cost is somewhat increased according to the operation of the after-cooler.
