Compared with conventional packed regenerator

internally heated regenerator is proposed to ac-hieve better regeneration performance.This study emphasized on both regeneration rate and regeneration thermal efficiency to evaluate the performance of both regenerators.The results indicated that internally heated regenerator could not only increase the regenerate rate

but also exhibit higher energy utilization efficiency.Different from adiabatic regenerator

internally heated regenerator can provide comparable regeneration efficiency and regeneration rate at low desiccant flow rate

so it should be a good alternative to avoid carryover of desiccant droplets.Higher air flow rate would result in a deduction of regeneration thermal efficiency although achieving higher regeneration rate.Suitable flow rate of the air should be considered carefully in liquid desiccant regeneration.The internally regenerator could have considerable prospect in liquid desiccantair conditioning application.
