- Abstract
- This paper aims to propose the numerical model of counter flow type liquid desiccant (LD) system and to compare the dehumidification effectiveness between the numerical model and empirical model to verify the accuracy of the predicting performance of the proposed numerical model. A heat and mass transfer correlations using NTU as an input parameter are employed to solve this system model equations for predicting dehumidifications effectiveness. The simulation results were compared with the results from the empirical model presented in existing literatures. The 24 groups are chosen based on the air properties conditions for the liquid desiccant performance test and the valid parameter range of the empirical model. For the 24 groups of both predicted and experimental results, the overall discrepancy is within 20%, which proves that the calculated results by the model accord well with the experimental findings.
