Claim 15:
16. A system for conditioning air for an enclosed space, the system comprising:
a process plenum configured to direct air from a process inlet to a process outlet, the process inlet receiving air at a first temperature and the process outlet supplying air to the space at a second temperature that is lower than the first temperature;
a first liquid-to-air membrane energy exchanger (LAMEE1) arranged inside the process plenum, the LAMEE1 comprising a first permeable membrane and configured to use a liquid desiccant flowing through the LAMEE1 to reduce the humidity of the air, a first concentration of water in the liquid desiccant at a fluid inlet of the LAMEE1 being lower than a second concentration of water in the liquid desiccant at a fluid outlet of the LAMEE1; and
a second LAMEE (LAMEE2) arranged inside the process plenum downstream of the LAMEE1, the LAMEE2 comprising a second permeable membrane and configured to use water flowing through the LAMEE2 to evaporatively cool the air, a temperature of the air at an air outlet of the LAMEE2 being lower than a temperature of the air at an air inlet of the LAMEE2.
