<p>PROBLEM TO BE SOLVED: To shorten regeneration time in a dehumidifier using a desiccant. SOLUTION: A dehumidifying side desiccant 18b of a desiccant unit 18 is located on a dehumidifying side passage 11 serving to dehumidify indoor air, and a regenerating side desiccant 18c of the desiccant unit 18 is located on a regenerating side passage 13 serving to release water from the regenerating side desiccant 18c, and further air fan means 17 and heating means are disposed on the regenerating side passage 13. The heating means is constructed with an electric heater 19 having positive resistance temperature characteristics where electric resistance is rapidly increased at a predetermined temperature, and the regenerating side desiccant 18c is regenerated with warm air heated by the electric heater 19, whereby the amount of fan air from the air fan means 17 in an initial stage of starting of the regeneration of the regenerating side desiccant 18c is increased, and the amount of fan air is reduced following the elapse of regeneration time of the regenerating side desiccant 18c.</p> |
