Description
この式の右辺のCO2減少量が人の呼気によるCO2増加量と同等であれば、CO2濃度を一定に保つことができる。
この装置は、室温でCO2を吸着し、その後、加熱ガスを流通するとともにCO2吸着材を加熱することによりCO2を脱離する構成を有している。
次に、室内空気を流通させることで、吸着材A部の有する顕熱を、加熱されていないCO2吸着材の一部(吸着材B部とする。)に輸送する。この熱輸送によって吸着材B部は加熱される。その後、可動なコイル状の導線を吸着材B部付近まで移動させた後、誘導加熱により吸着材B部を加熱する。吸着材B部は吸着材A部からの熱輸送により、温度Tまで加熱するための必要熱量が低減している。さらに、吸着材A部は該熱輸送により冷却されているため、CO2を再度吸着させるためにCO2吸着材を冷却するための時間及び必要な空気量が低減できる。
CO2吸着材を用いて選択的にCO2を除去する場合の消費電力を次の方法で試算した。消費電力は、次の計算式により算出した。
必要熱量は、CO2吸着材の加熱と及びCO2脱離熱の和として算出した。試算に用いた物性値を表1に示す。
換気によってCO2濃度を調整する場合に必要な電力、特に冷房に要する消費電力は、次の方法で試算した。
この式から、CO2濃度を低減するための電力は、10.5kJ/g−CO2と試算された。
図3は、CO2吸着材を用いた固定床方式により、室内空気のCO2濃度を低減するための構成例を示したものである。
比較例2において、加熱に必要な空気量は、次の方法で試算した。吸着材加熱に必要な熱量は実施例1と同等とし、熱は吸着材に流通する加熱空気の入口−出口のエンタルピー差より得られるとした。本法により必要な空気量は60.9g−Air/g−CO2と算出された。
図6Cは、図6Bの段階から更に進行した状況を模式的に示す図である。これらの図には、吸着材容器と、誘導加熱用磁場発生部を模式的に表したコイルと、吸着材容器内の温度を示すグラフと、を並べて示してある。
本工程を加熱工程−3とする(図6C)。
