给出了制冷剂R134a在由每英寸26个翅片（fpi）和40个fpi管构成的管束上冷凝的壳侧冷凝系数数据。测试的管束为五排宽五排深，交错排列，水平节距为22.2mm（0.875 in.）垂直间距为19.1毫米（0.75英寸）。这些数据是在35℃（95℉）的制冷剂饱和温度下，在18000到40000 W/m2（5700到12700 Btu/[hÃ151; ft2]）的管束热通量范围内获得的。 计算了管束的平均冷凝传热系数以及每排中间管的平均冷凝传热系数。数据显示，40 fpi管的性能优于26 fpi管。数据还显示，两种管几何形状之间的排间传热系数趋势存在显著差异。关键词:管壳式冷凝器、冷凝、传热系数、制冷剂、R134a、翅片管、性能、热流、饱和温度、测试、实验、比较引用: ASHRAE Trans。1994年，第100卷，第2部分，论文编号3806（RP-676），239-247，图8。，2个标签。，参考文献4。

Shell-side condensation coefficient data are presented for the condensation of refrigerant R134a on tube bundles constructed from 26-fin-per-inch (fpi) and 40-fpi tubes. The tube bundles tested are five rows wide by five rows deep and have a staggered tube arrangement with a horizontal pitch of 22.2mm (0.875 in.) and a vertical pitch of 19.1mm (0.75 in.). The data were obtained at a refrigerant saturation temperature of 35 deg C (95 deg F) over a bundle heat flux range of 18,000 to 40,000 W/m2(5,700 to 12,700 Btu/[h×ft2] ). Average condensing heat transfer coefficients for the bundle as well as average condensing heat transfer coefficients for the middle tube of each row were calculated. The data show that the 40-fpi tube performs better than the 26-fpi tube. The data also show a marked difference in the row-to-row heat transfer coefficient trends between the two tube geometries.KEYWORDS: shell and tube condensers, condensation, heat transfer coefficient, refrigerants, R134a, finned tubes, performance, heat flow, saturation temperature, testing, experiment, comparing
