%X A numerical model has been developed to study the latent effectiveness of the liquid to air membrane energy exchanger (LAMEE). The heat exchanger consists of two channels separated by a semi permeable membrane, which only allows water vapor transfer. The mass transfer across the membrane from the hot air to the cold liquid desiccant is investigated while employing different membrane types and different liquid desiccant solutions to predict the exchanger overall latent effectiveness using a Computational Fluid Dynamics (CFD) software. The LAMEE was configured in a cross flow configuration where the latent effectiveness of the exchanger was observed. Results indicated that the latent effectiveness is more influenced by desiccant solution type by 3.4 compared to changing the membrane type which has minor effectiveness increment by 1.3. The cross flow heat exchanger having LiBr as a desiccant coupled with a MCA membrane have improved overall latent effectiveness of 4.75 compared to that of LiCl desiccant solutions coupled with a CA membrane. The simulation results are product of the early development stage and require refining to ensure the accuracy and replicability. © 2018 Author(s).
