内容記述 | In this study, the heat transfer coefficient (HTC) and pressure drop of the new low global warming potential refrigerant mixture R1123/R32 (40/60 mass%) in a 6.0 mm OD horizontal microfin tube during condensation at 40 °C and evaporation at 10 °C are experimentally quantified. The data are then compared to the component R32. Both the condensation HTC and pressure drop of R1123/R32 (40/60 mass%) are somewhat lower than those of R32. Similarly, the pressure drop of R1123/R32 during the evaporation process at 10 °C is somewhat lower than that of R32. However, the evaporation HTC is comparable to that of R32. The lower surface tension of R1123/R32 can enhance the nucleate boiling and compensate the heat transfer degradation due to the volatility difference. | |||||
