摘要
本文对比和分析了水蓄冷、冰蓄冷、共晶盐蓄冷及气体水合物蓄冷技术的优缺点,提出在常规空调中采用纳米复合材料相变蓄冷技术,并对其相变温度和过冷度进行了实验研究。结果表明添加纳米TiO2可减少相变蓄冷介质的过冷度。
In this paper, the advantages and disadvantages of water cool storage,ice cool storage,eutectic salt cool storage and hydrate cool storage technologies were firstly compared and analyzed. Secondly, cool storage technology with phase change nanocomposites used in conventional air-conditioning system was presented, and the experimental study on phase change temperature and degree of super cooling were carried out. The results indicated that degree of super cooling could be decreased by adding nanometer TiO2 .
