Abstract

　水分吸着手段による除湿機能を有し、冷凍サイクルにおける凝縮排熱や低い温度帯の排熱を用いて水分吸着手段の再生が可能で、乾球温度が０°C以下においても安定した性能が発揮される冷凍空調装置を得る。 　水分吸着手段であるデシカントロータ１に、乾球温度が０°C以下の所定温度範囲の空間において、細孔径が５μｍ以下、さらに好ましくは２０ｎｍ以下、さらに好ましくは１～１．４ｎｍの吸着剤を担持させる。また、デシカントロータ１を回転させながら、冷凍庫内において、デシカントロータ１によって除湿された空気を風下に配置された蒸発器２０ｄに供給することで、蒸発器２０ｄへの着霜を防止するとともに、冷凍庫外において、風上に配置された凝縮器２０ｂの排熱により乾燥した空気をデシカントロータ１に供給することで、吸湿した吸着剤を乾燥させて吸着能力の再生を図ることができる。
