Effect of different solution regeneration reflux ratios on performance of liquid desiccant system

Presents the process of adjustable regeneration reflux ratio liquid desiccant system, and develops the mathematical models of the major components for the system. Simulates the energy consumption and the system coefficient of performance (COP) under the conditions of different dehumidifying load and solution regeneration reflux ratios. The results show that the overall performance of the liquid desiccant system can be improved by reducing the solution regeneration reflux ratio, the effect is intensified under the condition of lower solution regeneration temperature and dehumidifying load, and the decrease of reflux ratio is limited to the regeneration temperature, which exists an optimal solution regeneration reflux ratio.
