Abstract
In this study, four arrangements of the desiccant system with different Maisotsenko Cycle (M-Cycle) heat and mass exchangers (counter-flow and cross flow heat and mass exchangers) were selected for a comparative study. The proposed system is able to obtain high thermal COPs (up to 4.9) due to effective pre-cooling of the airflow with a highly effective evaporative heat and mass exchanger. The performance of the systems was analyzed numerically with ε–NTU models developed by the authors for moderate climatic conditions. To compare selected systems, different performance indicators were considered. These are the thermal COP (Coefficient of performance), the ERR (Energy Efficiency Ratio), and the humidity ratio decreases. The results show that the desiccant system with two counter-flow heat and mass exchangers (marked as System A) achieves highest humidity ratio decrease, as well as the highest thermal COP. In terms of the EER, factor for system with counter-flow and cross flow heat and mass exchanger (marked as System B) achieves highest effectiveness. There is a slight difference between COP values obtained by System A and System B. That is why it was concluded that System B is a solution which needs more analysis to be done to maximize this desiccant system potential.
