The second plenum receives heated air from an en- closed space and supplies cooled air to the space. The system also includes a first liquid-to-air membrane energy exchanger (LAMEE1) arranged inside the first plenum. LAMEE1 is configured to use a liquid desiccant to lower an enthalpy of the first air stream. A LAMEE2 is arranged inside the first plenum downstream of LAMEE1. LAMEE2 is configured to use the first air stream to evaporatively cool water flowing through LAMEE2. A first LAHX (LAHX1) is arranged inside the second plenum. LAHX1 is configured to directly and sensibly cool the second air stream using a first cooling fluid. A second LAHX (LAHX2) is in fluid communication with LAMEE1 and is configured to receive the liquid desiccant from LAMEE1 and cool the liquid desiccant using outdoor air.
