Abstract

Systems and methods are disclosed herein for a three-fluid liquid-to-air membrane energy exchanger (LAMEE) to condition air (a first overall fluid). A liquid panel assembly used in the LAMEE can include a first fluid circuit for a first cooling fluid (a second overall fluid) and a second fluid circuit for a second cooling fluid (a third overall fluid). The first cooling fluid, also referred to herein as a desiccant, can be configured to circulate through the liquid panel assembly and condition an air stream passing through the LAMEE. The second cooling fluid, also referred to herein as a coolant, can be configured to also circulate through the panel assembly and reject heat from the first cooling fluid. The second cooling fluid can increase the cooling capacity and overall performance of the LAMEE. The first and second cooling fluids can be separate from each other during circulation through the panel assembly. Low operating pressures of the first fluid circuit can be facilitated by the design of the liquid panel to at least partially offset hydrostatic pressure gain with friction pressure loss of the first cooling fluid.
