Flow condensation R134a, R450A, and R513A: IJHMT publication by Morrow and Derby

Experimental flow condensation heat transfer coefficient and pressure drop data are tabulated for R134a, R513A, and R450A in seven parallel 0.95-mm diameter mini-channels for a range of mass fluxes (i.e., 200–500 kg/m2s) and qualities (i.e., 0.2–0.8) at a saturation temperature of 40°C. The heat transfer coefficient uncertainties for all experiments were ± 6.3–21.2%, with an average of ± 9.8%. The data tabulated are the raw data from the paper “Flow condensation heat transfer and pressure drop performance of R134a alternative refrigerants R513A and R450A in a 0.95-mm-diameter minichannel,” accepted by the International Journal of Heat and Mass Transfer and its accompanying Data in Brief.本数据集制表汇总了制冷剂R134a、R513A与R450A在7根平行0.95毫米直径微通道内的流动冷凝换热系数与压降实验数据，实验工况覆盖质量通量范围为200~500 kg/(m²·s)、干度范围为0.2~0.8，饱和温度设定为40℃。所有实验的换热系数不确定度为±6.3%~±21.2%，平均不确定度为±9.8%。本次汇总的表格数据均源自论文《R134a替代制冷剂R513A与R450A在0.95毫米直径微通道内的流动冷凝换热与压降性能》，该论文已被《国际热质传递期刊（International Journal of Heat and Mass Transfer）》及其配套刊物《数据简报（Data in Brief）》收录。
