数据显示了几种浓度的不可冷凝气体对R123（R11的计划非氟氯化碳替代品）冷凝的影响，给出了四种增强管几何结构的管束——1024 fpm（26 fpi）管；一根1475 fpm（40 fpi）的低鳍管；和两个增强管，分别命名为Tu Cii和G-SC。测试束为五列宽五行深的交错管排列，水平节距为22.2-mm（0.875-in），水平节距为19.1-mm（0.875-in）。 垂直螺距为75英寸。在18000 W/m2（5700 Btu/h.ft2）和34000 W/m2（10780 Btu/h.ft2）之间的四种热流密度下，以体积计的四种氮浓度（0.5%、1.0%、2.0%和5.0%）对不凝性气体的影响进行了测试。所有数据均在35摄氏度（95华氏度）的饱和温度下获得。关键词:1997年，冷凝，制冷剂，R123，传热系数，二氧化氮，比较，翅片管，热流，测试，测量，实验，性能，氟碳化合物: ASHRAE Trans。1997年，第103卷，第一部分，论文编号4024（RP-676），149-163，图10。，4个标签。，裁判。

Data showing the effect of several concentrations of non-condensable gas on the condensation of R123 (scheduled non-CFC replacement for R11) are presented for bundles of four enhanced tube geometries - a 1,024-fpm (26-fpi) tube; a low-fin, 1,475-fpm (40-fpi) tube; and two enhanced tubes, designated the Tu-Cii and the G-SC. The test bundles are five columns wide by five-rows deep in a staggered tube arrangement with a 22.2-mm (0.875-in) horizontal pitch and a 19.1-mm (0.75-in) vertical pitch. Tests for the effect of noncondensable gases were conducted at four concentrations of nitrogen by volume - 0.5%, 1.0%, 2.0%, and 5.0%, at four heat fluxes between 18,000 W/m2 (5,700 Btu/h.ft2) and 34,000 W/m2 (10,780 Btu/h.ft2). All the data were obtained at a saturation temperature of 35degC (95degF).KEYWORDS: year 1997, Condensation, refrigerants, R123, heat transfer coefficient, nitrogen dioxide, comparing, finned tubes, heat flow, testing, measuring, experiment, performance, fluorocarbons
