Abstract
【解決手段】除湿と冷却を別けて除湿には夜間電力を使用して得られる氷蓄熱の低温冷水を使用し、顕熱冷却には間違っても結露事故が発生しないように、チラーの蒸発温度を室内空気の露点温度より高い温度に上げ、冷水の温度を20℃とし冷媒圧縮機の圧縮比を大幅に下げて無駄な冷却を全て改善し、冬季を含む概ね半年間は冷凍機を運転せず、冷却塔のみによるフリークーリングで20℃の冷水を賄う。

5℃冷水と20℃冷水の圧縮機に関する消費電力の比率は
0.301/1.242=0.24 76%の省エネルギーとなる。更に氷蓄熱の低温冷水を除湿に使用した他は全て顕熱冷却に使用すればターボ冷凍機の蒸発温度は21℃程度まで上がるので更に20%近く改善される事が見込まれる。
