Choi et al.investigated the convective boiling heat transfer coefficient of R-22,R-134a,and CO2 in horizontal minichannels with inner diameters of 1.5 and 3.0 mm constructed of stainless steel tube and a length of 2 m.They found that the average heat transfer coefficient ratio of R-22:R-134a:CO2 was approximately 1.0:0.8:2.0.They also proposed a heat transfer coefficient correlation based on the superposition model for refrigerants in minichannels.
