DEHUMIDIFIER

摘要

A dehumidifier is provided to regenerate a humidity absorbent material by waste heat generated in a fuel cell instead of using a heater, thereby reducing power consumption and improving energy efficiency of the dehumidifier. A dehumidifier includes a humidity absorbent material(40) having an absorbing part(42) for absorbing moisture from the air and a regenerating part(41) for emitting the absorbed moisture, and a regeneration path(20) for supplying air to the regeneration part, wherein the regeneration part carries out regeneration of the humidity absorbent material by reaction heat which is generated in the process of reaction of a fuel cell(100). The fuel cell includes an air cooling type heat exchanger, and a hot wind supply path(13) is formed between the fuel cell and the regeneration path for introducing the air to the regeneration path after heat transfer to heating medium in the heat exchanger.
