Dynamic analysis of mass transfer in a liquid desiccant dehumidifier

In this paper, a dynamic analysis of mass transfer in liquid desiccant dehumidifier is proposed. This analysis is performed via the calculated results from a model, which can presents dynamic properties of the system. Hybrid method is introduced to simplify the model and estimate the model parameters. Dynamic properties are preserved in the procedure of model simplification so as to completely describe the system properties. A time delay variable is added to compensate the slow response of the system. The dynamic analysis of mass transfer rate and outlet air humidity ratio condition is expatiated. This analysis is meaningful since it provides a numerical expression of the system under unstable working condition and the dynamic information obtained from this analysis is useful to the control strategy determination.
