ゼオライト‐水系ヒートポンプ，応用鉱物学の新分野

Abstract

Zeolite-water heat pump system has been discussed as an example of innovative applied mineralogy. Zeolite and water is a marvelous combination to use low temperature waste heat including the solar heat for air conditioning with-out using any other energy such as electricity. A simple and small test model of the heat pump system using Mg, Na-A type zeolite bed has enabled to make ice repeatedly in a glass tube of the diameter of 3cm. Only hot water at 100°C was used as the heat source for dehydrating the zeolite. The lowest temperature of ice reached -18°C. The system will be promised for saving energy through various applications by using huge amount of low temperature heat sources which are wasted now in vain in the world.
