| 摘 要： | 本文采用传统的热力学模型,理论设计了对制冷剂R141b适用的喷射器,通过计算机程序及优化设计理论设计出该喷射器.同时,背压是整个循环中的重要参数,过高的背压会影响喷射器的性能,本文还给出喷射器的最大背压计算方法,以此来设计出最适合整个工况运行的冷凝器,从而完成整个循环的设计.

| Abstract: | The thermodynamic mathematical model was adopted to design an ejector for the re- frigerant R141b.The ejector was designed with optimization design theory using computer program. The back pressure is the most important parameter in the design calculation.If the back pressure is too high,the ejector performance will deteriorate.The paper detailed the maximal back pressure calculation method,and based on this,the appropriate condenser was designed.Thus the design of the cycle finished. |
