The heat transfer characteristics of organic working fluid under supercritical pressures is essential for the research and application design of the organic trans-critical cycle(OTC) and organic supercritical cycle systems.In this study, the test facility was designed and built to measure the in-tube...
The condensing pressures are selected to be those that correspond to 30掳C. The measurements are all conducted with diabatic flows which start in the superheated (SH) region to observe how the onset of condensation affects the pressure drop. The visualizations of condensation are compared with the...

The results were obtained for temperatures between 0 and 40 C, and pressures ranging from 3 to 12 bar. Considering the didactic nature of the experimental setup, the obtained results agreed very well with the literature data. 展开 收藏 引用 批量引用 报错 分享 ...
The three-color hose, featuring yellow, blue, and red sections, is capable of withstanding a burst pressure of 3000 psi, ensuring that it can handle the pressures of most AC systems. With a working pressure of 600 psi, the hose is both flexible and robust, allowing for precise measurements...
