The paper describes results of investigations of heat transfer and flow resistance during bubble boiling of new environment-friendly refrigerating media. Experiment-based correlations to evaluate the heat transfer coefficients and flow resistance in the range of subcooled and developed bubble boiling are also put forward. They can be serviceable for the calculations and design of refrigeration heat exchangers operating with the application of new environment-friendly refrigerants. Results of calculations using own correlations are compared with those obtained from correlations by other authors.
