potential heat; residual heat
Technical term used in engineering, thermodynamics, or energy contexts to refer to heat that is stored, retained, or not yet utilized.
This system reuses the residual heat of waste materials.
Calculating potential heat requires specific heat and mass.
廃熱 (waste heat) is heat that is discarded, whereas 保有熱 can be heat that is retained and potentially usable.
Compound of 保有 (retention, possession) + 熱 (heat). The term is a modern technical coinage.
