熱交換器用高伝熱チタン板を用いた伝熱性能評価発表情報：2013年度日本冷凍空調学会年次大会講演論文集 ページ: A323-1-A323-2キーワード：概要：抄録：Ocean thermal energy conversion (OTEC) power system is highly expected as a renewable source of energy system. Plate-type heat exchangers (PHE) play significant important role on power generation efficiency of OTEC system because the energy is extracted from the small temperature difference, only around 20K between the warm surface layer and cold deep layer of the sea. Since a large quantity of seawater is used as the heating or cooling source to working fluid in the system, titanium is suitable for plate material in PHE because of its extremely excellent corrosion resistance to sea water.
