DEVELOPMENT OF DEHUMIDIFICATION FILTER USING NATURAL MESOPOROUS MATERIAL

Abstract

A new dehumidification filter using natural mesoporous material, Wakkanai siliceous shale, was developed for effective treatment of the latent heat load. The dehumidification ability of the developed filter was evaluated. It was demonstrated that this filter performed as an air-to-air heat exchanger under high rotating speed. The total heat exchange efficiency was 80% at 22 rpm. This filter removed 3.3 g/kg^DA of water vapor at 1 rpm when the regeneration temperature was 40°C. Moreover the rate of energy reduction to remove outdoor air load was estimated to be 56% by a combination of this filter and a sensible heat exchanger.
