Description
−効率が比較的高い。
−非常に単純なコンセプトである。低い複雑性で、安定した制御と自動化とが得られる。
−少数の部材及び機械によって、動作に関する大きな柔軟性が可能である。同様に、迅速な負荷変動は、大きな問題ではない。
−流体(例えば天然ガス)自体以外に、さらなる作動媒体が不要である。
−複雑性が低いゆえに、新しい方法は、低い誤差率と、従って、高い利用可能性とを提供し、これは、顧客の支持にとって非常に重要である。
−文献において理論的に扱われる他の方法とは異なり、部材の新規開発に関する費用が不要である。
−(例えば)天然ガスフローの間で大きな熱が伝達されることによって、周囲の熱によってさらに加熱されねばならない天然ガスの温度は、すでに非常に高い。これによって、費用効率がより高い熱交換器がもたらされる。なぜなら、今や、海水の凍結、又は、空気中の湿気の凍結がもたらす問題は、明らかに少なくなるからである。
