Abstract: |
Flow condensation heat transfer is of great significance for the performance of refrigeration system and is an important index of the refrigerant alternatives. In this paper, condensation heat transfer of the new alternative refrigerants is investigated. Recent developments of experiments measurement and relation models of condensation heat transfer of alternative refrigerants inside tubes are reviewed.The applicability and accuracy of correlations of condensation heat transfer for alternative refrigerants are discussed. The change of condensation heat transfer coefficients and pressure drops with influencing factors are summarized. |
