<p>PURPOSE: To simplify equipment and to supply the energy necessary for opera tion in the case of supplying low dew point air. CONSTITUTION: The air passage areas in a dry dehumidifier 3 is partitioned to five areas; a regeneration area 3b, high-temp. purging area 3c, low-temp. purging area 3d, dehumidifying area 3a, regeneration inlet area 3e. The air passage areas are so constituted that part of the return air from a dry room R is passed as purging air (QP) through the high-temp. purging area 3c→the regeneration inlet area 3e→the low-temp. purging area 3d in this order. The air past the low-temp. purging area 3d is mixed with introduced outdoor air (QOA) and is again passed through the dehumidifying area 3a of the dehumidifier 3. The regenerating air (QRB) is circulated within another system. The moisture in the regenerating air (QRH) is removed by a cooling dehumidifier 14 disposed in this system.</p> |
