Phase change materials
相変化材料は、固体と液体の相転移を利用した革新的な熱エネルギー貯蔵ソリューションを提供し、現在も主要な工学的課題に取り組むための研究が続けられている。

Phase Change Materials (PCM) store and release thermal energy through solid-liquid transitions at near-constant temperature, exploiting latent heat capacities orders of magnitude greater than sensible heat storage. Research spans material classes — paraffins, salt hydrates, fatty acids, eutectic mixtures — alongside critical challenges in thermal conductivity enhancement, supercooling mitigation, long-term cycling stability, and containment through micro- or macroencapsulation.

システムレベルの統合では、熱交換器の形状、PCMスラリー、ナノコンポジットマトリックスなどを考慮します。用途は、建物の温度調節やコールドチェーン物流から、グリッド規模のエネルギー貯蔵、宇宙船の温度制御まで多岐にわたります。
