Performance analysis of multi-partition desiccant wheel. 2. The detailed performance evaluation.

Author(s) : JEONG J., YAMAGUCHI S., SAITO K., et al.

Summary

A desiccant dehumidification system with air as working fluid can save energy consumptions because it can be driven by the low-grade waste heat below 80°C. If this system can be driven by the lower heat sources whose temperature is below 50°C, exhausted heat from the fuel cell or the air conditioner that exist everywhere can be used for the heat source. This leads to the great energy savings. This report evaluates the detailed performance of the four-partition desiccant wheel to achieve the great energy savings with the simulation and experiment (effect of the regeneration temperature, rotational speed of the desiccant wheel, cooling water temperature, process air flow rate and humidity of the ambient air). As a result, the performance of the four-partition desiccant wheel was evaluated in detail and for example, it was clear that there exists the optimum rotational speed to maximize the dehumidification performance.
