Abstract: The method of controlling a duration of an adsorption cycle in a process of adsorbing moisture from a gas, particularly air, using an adsorbing material including the steps of passing a moisture-carrying gas and a heated regenerating medium alternatingly through the adsorbing material in a series of alternating adsorption cycles and regeneration cycles, consists of monitoring, during a regeneration cycle, only a decrease of weight of the adsorbing material; comparing the decrease in weight of the adsorbing material to a preset value; and controlling the duration of an adsorption cycle immediately following the regeneration cycle according to the comparing. Alternatively, the method of controlling the duration of the adsorption cycle consists of monitoring, during an absorption cycle, only an increase of weight of the adsorbing material; comparing the increase in weight of the adsorbing material during the monitoring to a preset value; and switching to regeneration when the preset value is reached.

Abstract: The method of controlling a duration of an adsorption cycle is used in a process of adsorbing moisture from a gas, particularly air, using an adsorbing material including the steps of passing a moisture-carrying gas and a heated regenerating medium alternatingly through the adsorbing material in a series of alternating adsorption cycles and regeneration cycles. This method consists of monitoring, during a regeneration cycle, a parameter of the adsorbing material depending on a total amount of moisture adsorbed by the adsorbing material during an adsorption cycle immediately preceding the regeneration cycle; comparing the value of the parameter monitored to a predetermined value of the parameter related to an optimum quantity of moisture to be adsorbed by the adsorbing material during adsorption; and controlling the duration of an adsorption cycle immediately following the regeneration cycle according to the comparing.
