摘要: Abstract Experimental investigations of the heat transfer characteristics during charging were performed for a 25 wt% microencapsulated phase change material (MPCM), which was synthesized by polymerization. The shell and core urea-formaldehyde hexadecane (C16H34), respectively. shell–core ratio MPCM 3:7 weight. A direct mixing stratified water storage tank installed in experimental system to decrease chilled supply temperature fluctuation. influences different stirring rates on performance slurry also compared. results indicated that volumetric thermal energy capacity 1.74 times pure at 200 rpm. rate coefficient increased rapidly transition region, however, there is no significant improvement compared with whole process.
