摘要

以再生量和再生热效率为性能指标对内热型和绝热型再生器进行对比研究，研究结果表明：相对于绝热型再生器，内热型再生器不仅能提高再生过程再生量，而且还能够提高再生过程热利用效率。内热型再生器在溶液流量很小的情况下能够具有绝热型再生器在很大流量情况下同样的再生量，因此内热型再生器在保证较高的再生性能同时，还可以避免或者缓解带液问题。再生空气流量对溶液再生器的性能起到至关重要的作用，再生空气流量的虽然能够增加再生量，但是会引起能源利用效率——再生热效率的降低，因此再生空气流量应该慎重选择和决定。

Abstract

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.
