The results of an experimental study for the temperature and concentration dependencies of the density and viscosity of nsolutions of R600a/ mineral oil HF16-12 /C60 fullerenes are presented in the paper. The density measurements were performed by a pycnometric method in the temperature range 258-353 K. The viscosity was measured by the rolling ball method in the temperature range 253-283 K. Based on obtained experimental data, the effect of admixtures of compressor oil and additives C60 fullerenes on the density and viscosity of R600a was analyzed. It was shown that the additives of fullerenes contribute to lowering the viscosity of the working fluid (refrigerant R600a/mineral oil HF16-12) in entire range of experimental parameters. The working fluid R600a/mineral oil HF16-12/fullerenes C60 is recommended for application in domestic refrigeration.
