Characteristics of a Plate-Fin Heat Exchanger with Phase Change Materials
Краткое описание
A single-pass cross-flow heat exchanger with both fluids (air) unmixed, in which one or two kinds of phase change materials (PCM) were enclosed, was studied experimentally and analytically. This heat exchanger provides thermal energy storage and can be used to recover waste heat. Four kinds of heat exchangers were tested: The one with no PCM, others with lower melting point PCM and higher melting point PCM, one with both PCMs. Three kinds of experiments − steady, transient, and periodic experiments − were performed. A numerical analysis was carried out for periodic operation. From these results the characteristics of each heat exchanger were determined and suitable operating conditions were found.
