Dehumidifier - with a steamer

Japanese: 除湿器 - じょしつき

A device that draws in indoor air, brings it into contact with the surface of a cooler to turn moisture into droplets, and returns the dry air to the room. It is an application of the refrigeration cycle. The first commercial dehumidifier in Japan was released in 1952 and was used in warehouses, telephone exchange rooms, libraries, etc. As homes became more airtight, moisture damage such as condensation and mold on walls became more common, so in 1968, household dehumidifiers were released. Most have a dehumidifying capacity of about 4 to 5 liters per day. Recently, there are more and more air conditioners with dehumidifying functions, but there are few that have this function alone.

Japanese:

室内の空気を吸入し冷却器の表面に触れさせ水分を水滴状にし，乾燥した空気を室内に戻す機器。冷凍サイクルを応用したもの。1952年日本で初めて業務用除湿器が発売され，倉庫，電話交換機室，図書館などで利用された。その後一般住宅の気密性が高まるにつれ，壁の結露やカビが目立つなどの湿害が多発するようになったため，68年に家庭用除湿器が発売された。除湿能力は1日に4～5l程度のものが多い。最近ではエアコンに除湿機能のついた型がふえ，単独機能のものは少ない。
