EXPERIMENTAL STUDY ON CHARGING PROCESSES OF A CYLINDRICAL HEAT STORAGE CAPSULE EMPLOYING MULTIPLE PHASE CHANGE MATERIALS

摘要

This paper mainly deals with the charging processes of a cylindrical heat storage capsule filled with stearic acid, sliced paraffin and lauric acid as phase change materials. Experimental results demonstrate that, compared with the capsule with a single phase change material, the charging rate of the capsule employing these three phase change materials is enhanced obviously.
