PROBLEM TO BE SOLVED: To improve the dehumidification efficiency by heating a dehumidification rotor with a high efficiency with a PCT heater of simple configuration.SOLUTION: A dehumidifier 1 comprises: a disk-like dehumidification rotor 200, which adsorbs moisture out of treatment air passing through a treatment air path 2 and discharges moisture adsorbed into regeneration air passing through a regeneration air path 3; and a heating means 250 which heats the regeneration air and the dehumidification rotor 200. The heating means 250 has first and second PTC heaters 251A, 251B of rectangular shape each having a pair of short sides 254, 254 and a pair of long sides 255, 255. The first PTC heater 251A is provided with a pair of short sides 254, 254 disposed to cross the outer periphery of the dehumidification rotor 200, and the second PTC heater 251B is provided with long sides 255 aligned in the radial direction of the dehumidification rotor 200 and facing the long sides 255 of the first PTC heater 251A.SELECTED DRAWING: Figure 8 |
