Abstract
【解決手段】暖温の高超臨界圧冷却流体流れ50がガス冷却器100内で空気と間接熱交換して冷却される。冷却された高超臨界圧冷却流体流れ10がガス冷却器100から内部熱交換器110に入り、暖温化用の冷却流体と間接熱交換して冷却される。冷却された高超臨界圧冷却流体流れ10は内部熱交換器110からの流れ20として、図示される実施例では稠密相型のターボエキスパンダ120である膨張装置に送られ、冷却流体のエネルギーの臨界圧力よりも尚高い低圧側圧力のものとなる。膨張装置を通して膨張した流れ20は冷温の超臨界圧冷却流体流れ30として膨張装置を出る。冷温の超臨界圧冷却流体流れ30は前記暖温の高超臨界圧冷却流体流れ50を冷却することで暖温化され、かくして冷却負荷に冷却を提供する。これら2つの熱交換ステップは単一の熱交換器内で実施され得る。
