“…Currently, the authors of this review paper are working on the development and research of an innovative three-fluid flat-plate LAMEE at the University of Saskatchewan. Isetti et al [177] presented an innovative three-fluid LAMEE where water was employed to control the desiccant solution temperature. They used a commercial aluminum evaporator (225 mm Â 190 mm Â 58 mm) to manufacture a prototype for the three-fluid LAMEE at the University of Genoa.…”

“…It is commonly referred to as LAMEE (liquid to air membrane energy exchanger) [48]. The membrane is selected in such a way that it allows only the water vapour to pass through but not the desiccant [108]. Therefore, the desiccant carryover issues are avoided in the LAMEE.…”

“…While both approaches are energy-efficient in treating the latent load, the later one is more suitable to be adopted in EVs. Then, the absorbed water in the contactor is driven off in a second contactor (regenerator) and the desiccant concentration is restored [7].…”

“…In fact, due to the water vapor absorption (latent heat release) and heat transfer between the hot supply air and liquid desiccant, the temperature of liquid desiccant rises thus reducing the vapor absorption potential along the desiccant path. To deal with this issue, Isetti et al [7] drawn attention to the performance improvement of LDCs by designing and developing the first prototype of a combined membrane contactor, which is internally cooled by a refrigerant flow directly derived by a vapor compression cycle. Since then, there has been a growing number of experimental and numerical studies on the performance of internally cooled membrane-based dehumidifiers [8][9][10][11][12].…”

Investigation on the Performance of a Compact Three-Fluid Combined Membrane Contactor for Dehumidification in Electric Vehicles

et al. 2019

In this paper, the performance of a compact Three-Fluid Combined Membrane Contactor (3F-CMC) is investigated using Computational Fluid Dynamics (CFD), supported and validated with a good agreement by an experimental campaign made on a fully working prototype. This internally-cooled membrane contactor is the core component of a hybrid air conditioning system for electric vehicles (EVs) developed in a successful H2020 project called XERIC. In the adopted numerical approach, the conjugate heat and mass transfer inside the 3F-CMC is described by non-isothermal incompressible flows and vapor transport through a PTFE hydrophobic membrane. The sensitivity of the 3F-CMC performance to air/desiccant flow rates, temperature, humidity, and desiccant concentration is analyzed numerically through the validated CFD codes. According to this study, the moisture removal increases by the inlet humidity ratio, nearly linearly. Under the considered conditions (where the inlet air temperature is 26.2 °C), when the inlet relative humidity (RH) is 75% the moisture removal is about 450% higher than the case RH = 37%, while the absorption effectiveness declines about 45%. Furthermore, this study shows that the amount of absorbed vapor flux rises by increasing the airflow rate; on the other hand, the higher the airflow rate, the lower is the overall absorption efficiency of the 3F-CMC. This investigation gives important suggestions on how to properly operate a 3F-CMC in order to achieve the requested performance, especially in hot and humid climates.
