摘　　要：在研发的太阳能制冷系统前期的基础上,针对所需不同类型的蓄冷介质的优缺点进行分析比较,选择相变材料作为太阳能制冷系统的蓄冷介质。根据蓄冷要求,对两种新型微胶囊相变蓄冷材料(micro encapsulated phase change materials,简称MEPCM)进行了DSC热物性参数测试,并对测试结果进行分析比较,最终选取了相变温度为16℃的以石蜡为核心的微胶囊相变材料作为蓄冷系统的蓄冷介质。为相变蓄冷结合的太阳能制冷系统研究奠定了理论和试验基础。Based on the previous studies on the solar refrigeration system, this thesis, focusing on the analysis and comparison between the advantages and disadvantages of different cool storage media required,has chosen phrase change material as the cool storage medium for solar refrigeration system. In accordance with the requirements of the cool storage, DSC thermophysical property parameter tests on two new micro encapsulated phrase change materials （hereinafter referred as MEPCM） have been conducted, and the test result has been analyzed. The MEPCM with phrase transition temperature being 16＂C and paraffin as the core has become the final choice for cool storage system. This thesis thus lays the theoretical and experimental foundation for further studies on the solar refrigeration system combined with phrase-changing cool storage.
