説明
<p>In this paper, an experimental study on the condensation heat transfer coefficient of refrigerant R1234yf was obtained inside a 3.5 mm outside diameter (OD) horizontal microfin tube. Comparison of present work (3.5 mm OD) and previous research (2.5 mm OD) was reported to evaluate the effect of diameter to heat transfer coefficient. Data were obtained over a range of mass velocity from 50 to 200 kg m-2s-1, vapor quality 0 to 1, and saturation temperature from 20°C to 30°C. The effect of mass velocity, vapor quality, and saturation temperature on condensation heat transfer coefficient was clarified. The experimental results were compared with some existing correlations in the open literature. Hirose et al. (2018) correlation has good agreement with experimental data.</p>
