Description

Liquid-to-air membrane energy exchangers (LAMEEs) transfer heat and moisture between a liquid desiccant solution and airstreams through vapor-permeable membranes. Liquid desiccant membrane air-conditioning (M-LDAC) systems imple-ment LAMEEs to meet the latent or dehumidification loads in buildings. M-LDAC systems are better suited to dehumidify air than conventional air-conditioning (CAC) systems. One way to enhance the performance ofLAMEEsis to install cooling/heating tubes inside the solution channels to control the solution tempera-ture inside the LAMEE. Such an exchanger is called a three-fluid LAMEE. The main objectives of this study are to develop a Tran-sient System Simulation (TRNSYS) model of the three-fluid LAMEEand use it to simulate the performance of a three-fluidM-LDACsystemunderlow,medium,andhighlatentloadconditions. Theresultsshowthatthethree-fluidM-LDACsystemoutperforms the two-fluid M-LDAC system under the high and medium latent load conditions, whereas the two-fluid M-LDAC system outper-formsthe three-fluidM-LDACsystemunderthe lowest latentload condition.
