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.

Abstract: The application discloses an improved environmental control unit using in unitary combination a heat pipe as the heat source for the regeneration of the L-wheel. The heat pipe contains sodium metal which is vaporized by heating one end of the pipe in a firebox remote from the environmental control unit. The other end of the heat pipe extends into the heating section just upstream from the L-wheel. There, the air passing over the heat pipe surface, which optionally may be finned, causes sodium vapor in the pipe to condense, thus giving up its latent heat of condensation to the air stream, heating it to a temperature sufficient to dry the wheel. The improved heat pipe is efficient, safe, easily controllable and self-adjustable.
