| 摘 要： | 引言 氟氯烃在制冷空调行业的大量使用和排放,已经造成大气臭氧层的破环.根据1992年"蒙特利尔议定书"的规定,在制冷与空调工业中广泛采用的氯氟碳化合物(CFCs)制冷剂将被禁用.近年来,人们努力在寻找对环境无危害或危害小的制冷工质,并对这些工质的热力学性能进行深入的研究分析.随着禁止时间的迫近,有关R22替代物以及相应的冷冻机油的研究正在加紧进行.目前国际上呼声最高的HFC(氢氟化烷烃)类替代物有R407C和R410A.

| Abstract: | In order to improve the convective boiling heat transfer of R410A, the micro-fin tube was used to enhance heat transfer. The experimental studies on the horizontal micro-fin tube and smooth tube were conducted by using R410A as the working fluid. Several factors affecting heat transfer coefficients were analyzed, such as mass flux, heat flux, and quality. The circumferential wall temperature variation of the testing tubes with R410A as the working fluid was observed and analyzed. The heat transfer enhancement factor of the micro-fin tube against the smooth tube was about 1.6 to 2.2. The preliminary experiment data were useful for further research. |
