Abstract
Description the experimental unit for investigation of boiling process for the refrigerant/oil solution in tube is presented in the paper. The information about heat transfer coefficient averaged over cross section of the tube, local heat transfer coefficient and oil concentra-tions in R-600a at the various void fraction of the working fluid in evaporator have been obtained. The experimental data obtained have been analyzed.
