A study of heat transfer during saturated boiling of zeotropic mixtures of propane-isobutane (R290-R600a) and difluoromethane-tetrafluoroethane (R32-R134a) was carried out in a system of two microchannels 16 mm long (section 2x 0.2 mm) at mass fluxes up to 1350 kg/(m2· s). It has been established that under conditions of high mass fluxes, the latent heat of vaporization of the mixture does not have a noticeable effect on the value of the critical heat flux, and the critical heat flux is determined by friction in the channel. Keywords: boiling, binary zeotropic mixtures, critical heat flux, microchannels.
