[en] Desiccant wheels (DW) are key components in the desiccant evaporative cooling
systems used for air-conditioning in buildings. They dehumidify the air stream by adsorbing the water vapour contained in the air through sorption effect. The equations behind the physics of the DW can be complex to integrate into a system simulation tool. This paper offers a simplified approach to evaluate the performance of a DW by enhancing the similarities between the thermodynamic processes of evaporative cooling and desiccant dehumidification. The new performance indicator is defined similarly to the wet bulb effectiveness of direct evaporative coolers. It is then applied to a DW in operation in a real system installation.
