Performance investigation on a novel liquid desiccant regeneration system operating in vacuum condition

A comprehensive review of dehumidifiers and regenerators for liquid desiccant air conditioning system

“…Moreover, the problem of desiccant carryover is avoided in the V-LDEE as there is no requirement of regenerative air. Table-7 shows the differences between PB-LDEE and V-LDEE [102]. regeneration effectiveness of the BA-LDEE were 0.87 and 0.92, respectively [105].…”

“…The regeneration temperature in the LDAS depends on the dehumidification load and effectiveness of the LDEE, and the availability of the cooling energy source [10]. It varies between 50-80ºC for halide salt-based desiccants [102]. To reduce the regeneration temperature, Gao et al [103] proposed a flash evaporation technique for the regeneration process in the LDEE.…”

“…Due to the low regeneration temperature, V-LDEE reduces the energy consumption of the LDAS by 40%. In addition, V-LDEE improves the potential of the LDAS to utilize low-grade energy sources [102]. Moreover, the problem of desiccant carryover is avoided in the V-LDEE as there is no requirement of regenerative air.…”

Literature Review of Potential Thermally Activated Heat Pump Cycles

“…Yon, et al [12] proposed regenerating the desiccant thermally under reduced ambient pressure. A system was built with two connected compartments, both of which are under reduced ambient pressure.…”
