Résumé

The experimental investigation and calculations of the capillary constant and surface tension of Castrol Icematic SW 22 oil and R134a/Castrol Icematic SW 22 solutions were carried out. The data obtained are approximated by power dependencies with universal crossover functions at indices of power. The concentration relationship of the equation coefficients was investigated. The tables of reference data on the capillary constant and surface tension of R134a/Castrol Icematic SW 22 solutions in the range of operational parameters of vapour-compression refrigerating machines are calculated. The data obtained are interesting for specialists studying the processes of heat exchange in the evaporator of the refrigerating machine.
