“…The effect of the number and the diameter of the frames on the water vapor transfer rate have furthermore to be known for potentially required upscaling of the membrane area. During the runs with varying flow rate of the LiCl solution (see Table 3 runs (1) and (2)) the water temperature was adjusted to 25.0 • C, the temperature of the LiCl solution was kept at 25.6 during trial (1) and at 25.0 at trial (2). The calculated water vapor partial pressure difference was in the range of 24.4-25.2 Pa; temperature polarization effects [32] were not considered in this case.…”

“…Drawbacks of direct air/liquid contactors are the dependence of the interfacial contact area on the operation conditions (flow rate, pressure), the risk of flooding or unloading and particularly the risk of contamination of the air by desiccant droplets. In order to overcome these drawbacks a nondispersive absorption operation as provided by gas/liquid membrane contactors can be a beneficial alternative [1][2][3][4][5]. In this contactor arrangement the gaseous and the liquid phase are separated by a liquid tight semipermeable membrane.…”

“…The above analytical solution is used for the traditional flat plate heat exchanger. As for membrane-based liquid desiccant heat and mass exchanger, a novel technique is firstly presented in 1996 by Isetti et al [22] to stabilize the relative humidity of air in a museum by using a synthetic hydrophobic membrane coupled with a hygroscopic solution in a plane plate membrane contractor, as shown in Fig. 1.…”

“…Research on flat-plate LAMEEs started as early as 1996 when Isetti et al [115] presented a novel technique to control the indoor air relative humidity inside a museum display case by using a hydrophobic membrane that allowed simultaneous heat and water vapor transfer between air and a hygroscopic solution. The performance of the proposed technology was experimentally evaluated by comparing it with an uncontrolled display case.…”
