| Abstract: | The paper reviews the evaporation of R407C data currently available in the literature. The experimental rig and procedure are discussed. Experimental data about the evaporation for the pure R407C and R407C/oil mixtures in two smooth tubes and two enhanced tubes are also presented. The performance benefits of the micro-fin tube and corrugated tube are quantified and discussed. During tests inlet vapour quality was set 0 and outlet quality 0.7. Mass flux density varied from about 250 to 500 kg/m2 s. The experiments have been conducted for average saturation temperature 0 °C. |
