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.
