Dry Rooms

Achieving low-cost and energy-efficient DRY ROOM ^® facilities with appropriate equipment configuration and optimal operational control

Moisture in the air is an impediment to yield improvements in the manufacturing processes for the increasing production of rechargeable lithium-ion batteries and next-gen secondary batteries, which are expected to be widely used in the future. This manufacturing is therefore performed in a DRY ROOM ^®, which has the moisture in the air removed in a controlled low dew point environment.

The manufacturing cost for the dehumidified air used in the DRY ROOM ^® is higher than that for the conditioned air used in ordinary air conditioning. There are therefore increased demands for energy conservation in large-scale mass production factories. In order to respond to these demands, we optimized the configuration of the dehumidification equipment to achieve reduced energy consumption and lower cost. In addition, we achieve further reductions in energy consumption by implementing optimal operation controls to deal with the periods when the dehumidification load is low, for example, during the winter months.
