Investigations of bubble boiling in refrigeration heat exchangers.
Author(s) : BOHDAL T.
Summary
The paper describes results of investigations of heat transfer and pressure drop 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 bubble boiling are also put forward. They can be used for the calculations and design of refrigeration heat exchangers operating with the application of new environment-friendly refrigerants. The results of the calculations using own correlations are compared with those obtained from correlations by other authors.
