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.

Choi等人采用水平迷你型管道研究了R-22,R-134a和 CO2 的对流沸腾传热系数,管道的内径分别为 1.5mm和3.0 mm,由长度为2m的不锈钢钢管构成.他们发现三种物质的平均传热系数之比 R-22:R-134a:CO2 大约为 1.0:0.8:2.0.同时,他们基于迷你型管道制冷剂叠合模型提出了一个传热系数关系式.
