Abstract: A new 3-fluid liquid-to-air membrane energy exchanger (LAMEE) has been proposed to effectively meet sensible and latent loads. The 3-fluid LAMEE is composed of several adjacent air and solution channels separated by semi-permeable membranes, and refrigerant tubes that are installed within the solution channels to control the temperature of the solution in the LAMEE. In this paper, the performance of a dehumidification cycle of a 3-fluid liquid desiccant membrane air-conditioning (M-LDAC) system is presented and investigated through simulation and experimentation. The coefficient of performance (COP) of the M-LDAC system is evaluated at different inlet refrigerant temperatures. A system COP of 0.70-0.84 is required for neutral air conditions. The 3-fluid M-LDAC system effectively removes sensible and latent loads.
