Evaluation of refrigerants R600a, R290 and R1270 during flow boiling in a microchannels array. Comparison of data for hydrocarbons with previous data for R134a. Parametric analysis of heat transfer coefficient, pressure drop, ONB and exergy behaviors. Comparison of the experimental data and prediction methods from literature. In general, refrigerant R290 presents the best performance.
