Abstract
A vapor exchange medium comprises a multiplicity of porous desiccant particles and a binder holding the particles together to form a solid shape. The binder includes a multiplicity of substantially spherical, covalently-bonded silica particles derived from a silica sol which are small enough to ensure sufficient covalent bonding of the silica particles to maintain the structural integrity of the vapor exchange medium, yet large enough relative to the pore size of the desiccant particles such that the silica particles do not materially adversely affect the adsorption properties of the desiccant particles. The vapor exchange medium may be impregnated into a fibrous carrier to form a heat exchange element or device. A method and apparatus for making a heat exchange device or element for air conditioning are also disclosed.
