摘要通过实验方法研制了一种新型空调用有机相变蓄冷介质 HS-1,针对有机相变蓄冷介质导热系数
低的问题,采用纳米复合技术对有机相变蓄冷材料 HS-1 进行了改性研究。通过实验深入研究了表面活性
剂、超声时间、以及最佳超声时间下分散剂浓度对分散性的影响,最终确定了纳米 TiO2 复合有机相变蓄冷
介质(TiO2/HS-1)的制备的最佳分散条件。

Abstract A anic PCM for cool storage HS-1 (base liquid) used in central air-conditioning system was
developed by experimental method. The further research of using posite technology to anic PCM
HS-1 was made according to low thermal conductivity anic PCM. The influence of dispersant on dispersion,
time of supersonic on dispersion, consistence of dispersant in the best supersonic time and additive of nano and
non-nano on the dispersion were deeply researched by experiment. The best dispersion condition of preparation
for TiO2/HS-1 were confirmed at last.
