摘要
本文重点考察了HFC134a/矿物冷冻油/纳米TiO_2粒子工质体系中纳米粒子浓度和运行时间对冰箱性能的影响。实验结果表明:添加纳米粒子TiO_2之后,冰箱制冷系统性能提高,并随着纳米粒子浓度的提高而增大;冰箱长期运行性能稳定。
The investigation was imposed on the nanoparticles concentrations and system runtime for the refrigerator with HFC134a/Mineral oil/TiO2nanoparticles system. The results indicate that TiO2 nanoparticles added can increase the performance of the refrigerator, and the improvement of refrigerator performance was better with the nanoparticles concentration increasing. The refrigerator with this refrigerant system works normally and safely in a long runtime.
