A desiccant dehumidifier

Abstract

A desiccant dehumidifier includes a desiccant rotor, which is rotatably arranged about a center axis; a process air circuit arranged to conduct a process airflow through a process sector of the desiccant rotor; a regeneration air circuit arranged to conduct a regeneration airflow through a regeneration sector of the desiccant rotor; a purge air circuit arranged to conduct a purge airflow through a first purge sector and a second purge sector of the desiccant rotor; and an air fan arranged downstream of the desiccant rotor, which air fan is configured to generate the regeneration airflow in the regeneration air circuit and the purge airflow in the purge air circuit. The purge air circuit is arranged to conduct the purge airflow through the first purge sector in a first direction through the desiccant rotor, and through the second purge sector in a second direction through the desiccant rotor, wherein the first direction is opposite to the second direction.
