To provide a dehumidifying device and dehumidifying method each of which allows absorbed water to be efficiently extracted from a stimuli-responsive polymeric moisture absorbing material or a polymeric moisture absorbing material containing a stimuli-responsive polymeric moisture absorbing material, a dehumidifying device of an embodiment of the present invention includes (i) a stimulus providing section configured to provide an external stimulus to a stimuli-responsive polymeric moisture absorbing material or a polymeric moisture absorbing material containing a stimuli-responsive polymeric moisture absorbing material and (ii) a transfer section configured to transfer water released by the polymeric moisture absorbing material.

Dehumidification device and dehumidification method

The present invention achieves a moisture absorbing material which enables efficient dehumidification without supercooling or large heat quantity; and a dehumidifier in which the moisture absorbing material is used. The moisture absorbing material can be a dried product of a polymer gel in which an interpenetrating polymer network structure or a semi-interpenetrating polymer network structure is formed by (a) a stimuli-responsive polymer whose affinity with water changes reversibly in response to an external stimulus and (b) a hydrophilic polymer.

Hygroscopic material and dehumidifier using same

A humidity controlling apparatus comprises: a moisture absorbent (1) made of a macromolecular gelated moisture absorbing material which takes a first state being capable of absorbing moisture and a second state releasing in a liquid state the moisture absorbed in the first state, and which has a nature to change from the first state to the second state when a definite level of temperature or higher is attained, and return to the first state when the definite level of temperature or higher is no longer attained; and an energy converting particle (2) which is disposed so as to be buried inside the moisture absorbent and has a nature to generate heat when it is exposed to an external stimulus factor which is at least one of light, electric waves and a high frequency magnetic field.
