Control system and method for a liquid desiccant air delivery system

A method of operating an air delivery system, wherein the air delivery system includes a housing having a supply air channel and an exhaust air channel, wherein the supply air channel includes a supply air inlet configured to allow return air from an enclosed structure to pass into the supply air channel, and a supply air outlet configured to allow supply air to pass to the enclosed structure, and wherein the exhaust air channel includes an exhaust air inlet configured to allow air from the enclosed structure to pass into the exhaust air channel, and an exhaust air outlet configured to allow exhaust air to exhaust to an outside environment, the method comprising:

• opening each of a supply air inlet damper, a supply air outlet damper, an exhaust air outlet damper, and an exhaust air inlet damper during a normal operation mode;
• circulating a desiccant between an exhaust LAMEE disposed within the exhaust air channel and a supply LAMEE disposed within the supply air channel through a moisture transfer loop;
• closing the exhaust air inlet damper;
• closing the supply air outlet damper;
• opening a desiccant regeneration bypass damper that opens air flow between the supply channel and the exhaust channel;
• regenerating the desiccant within the exhaust LAMEE with the outside air during an off-hour period;
• storing regenerated desiccant within a desiccant storage tank that is fluidly connected to the exhaust LAMEE;
• and
• tapping the regenerated desiccant during the normal operation mode.
