Abstract
Sensible/latent heat transfers in a two rotor desiccant cooling process have been experimentally discussed to clarify the effect of water spray evaporative cooler at the inlet of return air stream on the process performance. It was found that the cooling performance was accelerated by the additional evaporative cooler since the enthalpy reduction in the sensible heat exchanger was enhanced by a larger temperature difference between both air streams. This behavior was more realized at higher temperature or lower humidity in the ambient air. On the other hand, a drop in dehumidifying performance due to humidity increase in the regeneration air was compensated by the larger enthalpy reduction in the sensible heat exchanger.
