A total of 1210 new condensation friction pressure gradient points (database) is collected from 12 open articles on mini/
micro-channels literature. The database covered a wide range of thermophysical properties associated with low-GWP
refrigerants, physical dimension, mass velocity and vapor quality. A comparison of the experimental database against
eleven two-phase flow frictional pressure drop prediction tools is carried out. Based on that, the mini/micro-channel
developed by Xu and Fang exhibited the best ability to capture the tendency of the database with a mean absolute relative
deviation of (36.59%) for all data.
