Document Type and Number:
Japanese Patent JP2021031635
Kind Code:
A
Abstract:
To provide a moisture absorbing/desorbing material exhibiting both high moisture absorbing/desorbing property and high moisture absorbing/desorbing rate by solving problems that while performance of an adsorption type heat cycle is determined by how fast a large moisture absorption amount is obtained, that is an amount and a rate of moisture absorption, however, with a conventional moisture absorbing material there is a limitation of the performance of the adsorption type heat cycle because an excellent amount and an excellent rate of moisture absorption are not satisfactorily compatible with each other, so that downsizing of the device is difficult and not so popularized, especially in an adsorption type refrigeration cycle for vehicles with a limitation in an installation volume, performance deficiency of the moisture absorbing material is significant and hampers practical application.SOLUTION: A porous moisture absorbing/desorbing polymer particle is characterized as being an organic polymer containing a salt type carboxy group of 5.0-8.0 mmol/g and having a crosslinked structure, and having a meso pore with a specific surface area of 0.1 m2/g or more and with an average pore diameter of 2.0-50.0 nm.SELECTED DRAWING: None
