The hot reactivation air stream in a desiccant wheel dehumidifier primarily serves to dry out the saturated desiccant. This process helps restore the desiccant's effectiveness by using heated air to release the moisture it has absorbed. Consequently, this allows the dehumidifier to continue functioning optimally. ;
The hot reactivation air stream in a desiccant wheel dehumidifier primarily serves to dry out the saturated desiccant, restoring its effectiveness. Heated air passes through the desiccant, releasing moisture it has absorbed and enabling continuous operation. Therefore, the best answer is D. dry out the saturated desiccant.
