Conceptual solid desiccant cooling cycle with new dehumidifier configurations

Desiccant cooling cycle utilizes waste heat as energy source. In this paper, a conceptual solid desiccant cooling cycle with lower increase in air temperature during dehumidification is presented. The ratio of temperature rise during dehumidification at desiccant bed is proposed. It is predicted that a lower ratio of temperature rise may improve the ability of the cycle to reduce the temperature of supply air. Then, three configurations of dehumidifier/desiccant bed that could mitigate the rise in air temperature are briefly discussed. Although this paper does not include any mathematical models to predict the performance of those proposed configurations, the conceptual strategies presented may contribute to a breakthrough in desiccant cooling cycle.
