摘　　要：本文阐述了纳米流体、微胶囊及定形相变材料等新型相变材料的研究现状,以及相变材料在空调蓄冷系统中的应用,归纳出了相变过程的一般规律和特殊性问题,对蓄冷设备的蓄冷量、蓄冷速率等参数的影响因素展开了分析,并对混合蓄冷、相变蓄冷型太阳能空调系统以及相变蓄冷型潜热输送空调系统等新型空调蓄冷系统进行了介绍和评价。相变蓄冷材料有着适宜的相变温度和较高的蓄冷密度,应用于空调蓄冷系统可提高制冷机效率,对于建筑节能具有重要意义。In this paper, the research status of new type phase change materials was described, such as nanofluid, microcapsule and fixed shape phase change materials, as well as the application of phase change materials in cold storage air-conditioning system. Furthermore, general rules and special problems during phase change were summarized, the influencing factors of parameters such as cold storage capacity and cold storage rate in cold storage equipment were analyzed, and new type cold storage air-conditioning systems were introduced and evaluated, including solar air-conditioning system of mixed cold storage and phase change cold storage and phase change cold storage air-conditioning system with latent heat transfer. Phase change cold storage materials had suitable phase change temperature and relatively high cold storage density, and their application in cold storage air-conditioning systems would improve the efficiency of refrigerators ,thus of great significance in building energy conservation.
