PERFORMANCE STUDY OF A DOMESTIC REFRIGERATOR USING R134a/MINERAL OIL/NANO-TIO2 AS WORKING FLUID

摘要：

A new refrigerator test system was built up according to the national standard. The reliability and performance of the refrigerator were investigated experimentally by using R134a/mineral oil/TiO2 nanoparticles substituting for R134a/Polyol-ester. The energy consumption test, freeze capacity test and the system running properties monitoring were conducted under the same conditions. The results indicate that R134a/mineral oil/TiO2 nanoparticles works normally and safely in the refrigerator. The refrigerator performance was better than the R134a/Polyol-ester system, and the 0.06％ mass concentration save 21.2 percent energy compared to the R134a/Polyol-ester system, 0.1％ proportion can save 26.1％. Therefore, it is feasible to use R134a/mineral oil/TiO2 nanoparticles as a refrigerator working fluid without any system reconstruction.
