Flow boiling heat transfer performance of non-azeotropic refrigerant mixture R32/R134a in the horizontal microfin tubes with different sizes was investigated. The dependencies of forced flow boiling heat transfer coefficient of R32/R134a on mass flow rate
heat flux and quality were studied and the mechanism of flow boiling heat transfer under each working condition were analyzed. The experimental data indicated that the component of R32 has affected the heat transfer coefficients of the mixture. For comparison
the performance of heat transfer of R22 in microfin tubes was also studied.
