Energy storage materials for phase change heat devices recovering industrial waste heat for heating purposes
The abundance of industrial waste heat resources offers valuable opportunities for the utilization of phase change heat exchangers in clean energy applications. This study focuses on the innovative development of binary phase change material (PCM) composed of paraffin and stearic acid (SA) in various ratios, aimed at optimizing waste heat recovery. Comprehensive analyses of the phase change temperature, latent heat, and thermal conductivity of these mixtures were conducted. The research identified a mixture with a 20 % paraffin and 80 % stearic acid ratio, which exhibits a phase change temperature of 62.73 °C and a latent heat of 205.53 J/g. This mixture stands out due to its minimal subcooling and consistent thermal properties, making it highly effective for low-temperature waste heat recovery. Additionally, a novel process design and simulation system for using these materials in heat exchangers to convert intermittent industrial waste heat into continuous thermal energy for heating were developed.
期刊介绍：
International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
