Patent number: 6050100Abstract: A method of conditioning a process stream of air in an air conditioning system wherein a process stream of air is dehumidified and cooled to provide a conditioned stream of air for introducing to a conditioned space. The method comprises the steps of providing an adsorption wheel having a multiplicity of passages through which process air can flow for adsorbing moisture therefrom, the wheel capable of adsorption of moisture from the process air and of regeneration on a continuous basis as the wheel rotates. An indirect evaporative cooler is provided having a dry side and a wet side separated by a moisture-inpervious wall wherein heat is extracted from said dry side through the wall to the wet side. Cooling in the dry side is achieved by evaporation of water into air passing through the wet side. The process air is passed through the adsorption wheel to remove moisture therefrom to provide a moisture-depleted stream of process air exiting the adsorption wheel.Type: GrantFiled: November 4, 1997Date of Patent: April 18, 2000Assignees: Novel Air Technologies, L.L.C., ACMA LimitedInventors: William A. Belding, William D. Holeman, Chiang Lam

Patent number: 5580369Abstract: An improved adsorbent composition for a natural gas-fired, adsorption cooling system that readily adsorbs moisture from ambient air, while being readily regenerated at high temperatures up to 200.degree.-300.degree. C. in order to provide an enhanced coefficient of performance to the system. Such an adsorbent composition may comprise an A-type zeolite, an X-type zeolite or a chemically modified Y-type zeolite either alone, in conjunction with each other or in conjunction with alumina and/or silica gel. A rotating adsorbent wheel may be fashioned from corrugated paper comprising the adsorbent composition and a slurry of synthetic, organic fibers which are preferably polyaramid fibers. The strength of the wheel may be enhanced by surface treating it with sols or salt solutions of alumina or silica, and a highly temperature-stable epoxy or phenolic resin.Type: GrantFiled: January 30, 1995Date of Patent: December 3, 1996Assignee: LaRoche Industries, Inc.Inventors: William A.

Patent number: 5542968Abstract: Disclosed is a gas permeable, sensible and latent heat exchange media having a multiplicity of passageways therethrough through which an air stream can flow, the sensible and latent heat exchange media. The heat exchange media comprises a fibrous support material, a finely powdered desiccant material and fire retardant contained in the fibrous support material. The fibrous support material and the fire retardant are capable of adsorbing sensible heat from a warm air stream and releasing the absorbed sensible heat into a cool air stream as the air stream flows through the sensible and latent heat exchange media. The desiccant material is capable of adsorbing moisture from a humid air stream flowing through the sensible and latent heat exchange media and capable of releasing the adsorbed moisture into a dry air stream flowing through the passageways of the sensible and latent heat exchange media.Type: GrantFiled: January 24, 1995Date of Patent: August 6, 1996Assignee: LaRoche Industries, Inc.Inventors: William A.
