After that, the air is discharged through an air system and the first dehumidifying tank is cooled using the part of the air. This process is repeated in the first and the second dehumidifying tanks by turns. Thus, air discharge amount is minimized to save energy and both dehumidifying tanks are cooled without an additional heater.
