Claim 22:
23. A method of conditioning air for an enclosed space, the method comprising:
directing air through a process plenum having a plenum inlet and outlet, the air entering the plenum inlet at a first temperature;
directing the air through a liquid-to-air energy exchanger (LAMEE) arranged inside the plenum, a first moisture content of the air being higher at a LAMEE inlet compared to a second moisture content of the air at a LAMEE outlet;
directing a desiccant through the LAMEE, the desiccant and air separated by a membrane of the LAMEE, the LAMEE configured to remove heat and water from the air using the desiccant, a first concentration of water in the desiccant being lower at a LAMEE inlet compared to a second concentration of water in the desiccant at a LAMEE outlet, the desiccant at the LAMEE outlet being a dilute desiccant;
directing the air through a direct evaporative cooler (DEC) arranged inside the process plenum downstream of the LAMEE to cool the air; and
delivering the air to the enclosed space, the air exiting the plenum outlet at a second temperature lower than the first temperature.
