实验测量了毛细管吸气管换热器的压力和温度分布。具体而言，在与实际运行的R-12制冷剂系统类似的条件下，以一英尺的间隔测量毛细管压力、管壁温度和吸入管路流体温度。结果表明，毛细管的传热行为与绝热毛细管有很大不同。对结果的分析为毛细管吸入管换热器的运行提供了重要的见解，得出了一些新结论。具体来说，热量的传递增加了两个管道的长度- 相区，同时减少流动限制。此外，沿换热器向出口方向的传热速率增加，因此大部分传热发生在两相区。文中还讨论了其他几个重要的观察结果。引文:ASHRAE Transactions，1984年，第90卷，pt。密苏里州堪萨斯城2A号

The pressure and temperature distribution along a capillary tube-suction line heat exchanger was experimentally measured. Specifically, capillary tube pressures, tube wall temperatures, and suction line fluid temperatures were measured at one-foot intervals under conditions similar to those of an actual operating R-12 refrigerant system. The results showed that the behavior of a capillary tube with heat transfer is considerably different from an adiabatic capillary tube. An analysis of the results provided significant insight into the operation of a capillary tube-suction line heat exchanger, resulting in several new conclusions. Specifically, the transfer of heat increases the length of the two-phase region while simultaneously reducing the flow restriction. Additionally, the rate of heat transfer increased along the heat exchanger toward the exit, so that most of the heat transfer occurred in the two-phase region. Several other important observations also are discussed in the text.
