本文研究了在水层中填充相变蓄热材料的微细微胶囊的蓄热特性。采用热空气泡直接接触热交换的方法对微胶囊进行蓄热。该微胶囊以正构烷烃为芯材，蜜胺树脂为包覆材料。实验研究了潜热储存完成时间与一些参数的关系。推导了微胶囊相变蓄热过程完成时间与微胶囊粒径与水层高度之比、气流雷诺数、气流绝对湿度的Stefan数和修正Stefan数的无量纲关联式。
This paper has dealt with the heat storage characteristics of fine microcapsules packed with latent heat storage material in the water layer. The heat storage operation to the latent microcapsules was carried out using hot air bubbles by direct contact heat exchange. The microcapsule consists of n-paraffin as a core latent-heat storage material and melamine resin as a coating substance. The relation of the completion time of latent-heat storage to some parameters was examined experimentally. The non-dimensional correlation equations for the completion time of latent-heat storage process had were derived in terms of the ratio of water layer height to diameter of microcapsule, Reynolds number for air flow, Stefan number and modified Stefan number for absolute humidity of flowing air.
