The characteristics of the heat transfer to nonazeotropic refrigerant mixtures of HCFC22 and CFC114 flowing in a horizontal evaporator tube were experimentally investigated. The heat transfer to the mixture was significantly degraded due to a mass transfer resistance in the region where nucleate boiling contributes substantially to the heat transfer, but such degradation was little in the forced convection dominated region. This little effect of the mass transfer resistance in the forced convection dominated region was theoretically confirmed based on a convective evaporation model for an annular two-phase flow of the mixture. A circumferential variation of the heat transfer coefficient, which was observed in the annular two-phase flow of the mixture, was theoretically explained to be attributed to the circumferential composition variation caused by the nonuniform liquid film thickness.
