摘　　要：主要研究由硬脂酸、切片石蜡和月桂酸三种相变材料组合的圆柱型储热单元的储热特性。测试结果表明 ,与单一相变材料的储热单元相比 ,组合相变材料的储热单元的储热速率明显提高。This paper deals with the charging process of a cylindrical heat storage capsule filled with stearic acid, sliced paraffin and lauric acid as phase change materials. The experimental results demonstrate that, compared with the traditional heat storage capsule using single type of phase change material, the charging rate of the capsule with the three types of phase change materials increases considerably.
