Effect of rotational speed on the performances of a desiccant wheel

► The performance of desiccant wheels depend on several operational parameters. ► The rotational speed of desiccant wheels is widely recognized as a key parameter. ► The desiccant can be regenerated with low-temperature thermal energy (60-70 °C). ► Optimal speed for dehumidification performance depends on the operating conditions. ► Sensible energy ratio is monotonically increasing with rotational speed.
