HEAT EXCHANGE MATERIAL BY HOLLOW SPHERICAL STRUCTURAL PARTICLE HAVING MOISTURE-PERMEABLE MICROPORE

摘要

PROBLEM TO BE SOLVED: To provide a use of fine particles having a hollow spherical structure with moisture permeable micropores usable as a heat exchange material having micropores such as those of zeolite for a heat pump, etc. SOLUTION: This heat exchange material is characterized in that the heat exchange material comprises hollow spherical structural particles having an allophane or allophane-like structure as a constitutent element and is composed of fine particles having a structure with small pores in which water molecules move in and out of the small pores on the outer walls of the hollow spherical particles. The heat exchange material comprises the fine particles composed of allophane.
