Measurement of Vapor Liquid Equilibrium for Difluoromethane (R32) +Fluoroethane (R161) + 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf)

open access: yesZhileng xuebao, 2018
In the study, we focused on the vapor-liquid equilibrium property of the ternary system of R32+R161+R1234yf. The vapor–liquid equilibrium data was measured via a liquid-circulation apparatus at temperatures from 283.15 K to 323.15 K.
