摘要
利用稳态法,分别以R134a/冷冻机油、R134a/纳米冷冻机油为研究对象,对其饱和蒸气压进行实验研究.冷冻机油为SUNISO 3GS,在制冷剂/冷冻机油混合物中的质量分数分别为1%、3%和5%.纳米冷冻机油中纳米NiFe2O4的含量为3 g/L,实验温度范围为263～333 K.结果表明:当温度相同时纳米冷冻机油/R134a混合物的饱和蒸气压明显低于纯R134a,二者之间的差值随着含油量的增加而增大.
The saturated vapor pressure of R134a/refrigeration oil mixture and R134a/ nano-refrigeration-oil mixture is studied in the paper by using stable state method.The refrigeration oil is SUNISO 3GS,and the mass fraction is 1%,3% and 5% in the refrigerant/refrigeration oil mixture.The mass concentrations of nano-NiFe2O4 particles in nano-refrigeration-oil is 3g/L,and the experimental temperature range is between 263 to 333 K.Results show that： when the mixtures have the same temperature,the saturated vapor pressure of nano-NiFe2O4 refrigeration oil/R134a mixture is lower than the pure R134a,and the pressure deviation of nano-NiFe2O4 refrigeration oil/R134a mixture is increased with the increase of oil content.
