Abstract
A method to desorb water from a desiccant of an air recharge system comprises the steps of a) filling a purge reservoir using an air compressor and a desiccant dryer to produce discharge air, b) stopping the air compressor; c) back purging the desiccant, and d) vent resetting the system, wherein the filling a purge reservoir step does not result in an addition of discharge air to an air storage tank in fluid communication with the purge reservoir and wherein the air storage tank is filled with an amount of the discharge air such that the air storage tank is at a full storage tank pressure prior to filling the purge reservoir. A method of filling an air storage tank of an air recharge system is also disclosed.
