Possibilities of Conjugating Binary Solutions for Thermal Energy Storage

摘要

A concept for thermal energy storage (TES) has recently emerged that depends on the heats of mixing of a pair of different liquids at a critical solution temperature. Liquid pairs that mix or unmix at a critical solution temperature (CST) are called conjugating binary (CB) systems. The possibilities of the concept for chill and heat storage for residential and commercial purposes are reviewed and the results of material searches for the different applications reported. An economic analysis of the concept for commercial chill storage shows that the concept compares favorably with ice storage systems. (ERA citation 09:046037)
