摘要/Abstract

摘要：

设计了一种内热源盘管作为填料支架、溶液和空气采用逆流换热的内热型再生器，并将其用于一种冷凝热分段利用的热湿独立处理空调系统中，可大幅度提高再生性能。搭建了逆流内热型再生器实验台，以氯化锂溶液为除湿剂，研究了溶液温度、流量，空气温度、流量对再生热效率和再生量的影响，结果表明内热型再生过程中应尽量避免通过提高空气进口温度来提高再生性能。并将内热型与绝热型再生过程进行了对比研究，结果表明内热型再生器再生量高于绝热型再生器。

Abstract:

In this study, an internally heated counter-flow regenerator with coil tube as support of the packing is used in the novel hybrid liquid desiccant air conditioning system with sectional utilization of condensation heat to improve the effectiveness of the regeneration process. Such an internally heated counter-flow regenerator has been fabricated and tested with lithium chloride solution as liquid desiccant. The effect of the solution temperature and flow rate, air temperature and flow rate on the regeneration rate and regeneration thermal efficiency were discussed, and the results demonstrate that it would be better to avoid improving regeneration effectiveness by heating the regeneration air. Performance comparisons showed that performance of the internally heated regenerator was superior to the adiabatic one.

Key words: regeneration, regenerative thermal efficiency, regeneration rate, heat transfer, mass transfer
