Caloric properties of R600a solutions in compressor oil containing fullerenes C60
Number: pap. 1176
Author(s) : ZHELEZNY V., FAIK A., KHLIYEVA O., et al.
Summary
New experimental data on the saturated liquid heat capacity for the R600a/mineral oil solutions (ROS) is reported in the paper. Data on the two-phase isochoric heat capacity was obtained for different oil fractions of the refrigerant in the temperature range from 260 to 330 K. The obtained information was used to calculate the caloric properties of the ROS. Moreover, an influence of fullerenes C60 on the caloric properties of mineral oil was examined. The measurements of the heat capacity for the ROS, compressor oil and compressor oil containing fullerenes C60 were performed using an experimental setup, which implements a direct heating method in adiabatic calorimeter. In addition, the heat capacity of oil and oil containing fullerenes C60 was measured using differential scanning calorimetry. The effect of increasing the heat capacity of the compressor oil with the additives of 0.0020 kg·kg-1 of fullerenes C60 was observed.
