Abstract: A desiccant system, particularly adapted for a method of operation of an open-cycle air-conditioning system, comprising the use of thin sheets or layers of fibrous materials, such as a ''''paper'''' of cellulose, asbestos, fiberglass, polyesters, Teflon, Kel-F, or nylon, which have been impregnated, during their manufacture, with varying amounts of finely powdered, solid, natural or synthetic, crystalline, alkali metal or alkaline earth metal alumino-silicates, such as zeolites or ''''molecular sieve'''' materials. The impregnated papers are then formed into moisture transfer bodies, such as an L-wheel formed of corrugated paper rolled up so that the corrugations form axial passages through the wheel. A wheel of such construction can more effectively dry the ambient air without degradation by combustion products or desiccant weeping to a much lower level of humidity than prior art desiccant systems. Also, based on the vapor pressure and kinetic data and the energy required to regenerate the L-wheel, a system according to our invention would be significantly improved over the prior art and result in a higher coefficient of performance for the system, an increased depth of drying, and a reduction in wheel size. The system is particularly applicable to drying, for example, humid air having a 92* F. dry bulb temperature and an 80* F. wet bulb temperature to a moisture content of less than .003 lb. H2O/lb air.
