IIR documentSummary
In conventional liquid desiccant system, the diluted solution after dehumidification is usually completely sent to the regenerator, which leads to the poor system performance. This paper tries to study on the effect of the solution regeneration reflux ratio on the overall system. Firstly, the novel configuration of liquid desiccant system that can adjust the reflux ratio of regeneration was put forward. Then, the major components of the system were modelled mathematically. Lastly, energy consumption and the system coefficient of performance (COP) under different conditions, including different moisture-removing load and varied solution regeneration reflux ratio, were simulated. The results show that, the overall performance of the liquid desiccant system can be improved by reducing the solution regeneration reflux ratio, moreover, the improving effect are stronger under lower solution regeneration temperature and lower moisture-removing load. However, the reflux ratio cannot be reduced unlimited since the regeneration temperature will be higher, thus there is a rational optimal solution regeneration reflux ratio.
