冷藏车用新型相变蓄冷材料的研究

Study on new cool storage materials for refrigerated vehicle

阐述了蓄冷板冷藏车技术的研究现状,对比分析了结晶水合盐蓄冷与有机物蓄冷的优缺点.针对蓄冷板冷藏车对相变蓄冷材料的要求,提出了一种A级冷藏车用的新型相变蓄冷材料,进行了相变温度测试,结果表明该介质的相变温度为-6.9℃,是一种适用蓄冷板冷藏车蓄能介质.

The cool storage technology used in refrigerated vehicles is summarized,the advantage and deficiency of hydrated crystalline salt storage and organic matter storage are compared and analyzed.The requirements for phase change material characteristics of storage plate refrigerated vehicles were brought forward,and a new phase change material prepared for A level refrigerated vehicles is tested.The results show that the melting temperature is about-6.9 ℃,and the new phase material is a potential cool storage material for research.
