Form development of clay module for optimize evaporative cooling with wind flow

Abstract

Evaporative cooling is one of most important passive cooling systems which is used since ancient times. As a passive cooling system direct evaporative cooling is the basic method. There are most of evidences in use of wetted clay material in evaporative cooling method. Mashrabya and wetted clay conduits used in wind towers are the proofs on this passive cooling system. Clay exhibit excellent properties on evaporative cooling as a porous material. Porous ceramics exhibit properties such as high permeability, low bulk density, high surface area, and low thermal conductivity. There are more possibilities on enhancing the evaporative cooling. The research focused on the form development which multiplying the cooling efficiency. Provide a large surface area to air touching, access to easy air flowing and making a speed for air flow are the archived aims which are multiplying the cooling effect in the research. Various forms have tested in the research with the smoke flows as air flow and identified best form. And the form has developed with the literature which is about clay form development. Close ended form of clay has identified as more efficient on the evaporative cooling. This basic form has a possibility to develop as a sustainable product design for people. The formed product changes the situation of Natural wind or created wind flow as a chilled air by the evaporative cooling in zero energy. In a warming world, heating energy demands should reduce while cooling energy demands rise. Further investigations of the form development respond for this circumstance as a design solution.
