| 摘 要： | 使用机械压缩机的制冷循环(RAC/MC)和使用喷射器的冷却循环(EJC)进行复合,得到的新型节能循环系统即CCRS,COP值比单独压缩制冷循环系统的COP有明显提高。本文通过分析表明,合理的CCRS喷射冷却循环工况对GOP值的提高有很大影响;喷射工况一定时,当发生器中温度变化时,系统存在着一个最佳工况点;使用不同的工质,系统的性能也有明显的差异。

| Abstract: | The new energy-saving cycle combined with the refrigeration cycle using mechanical compressor (RAC/MC) and the ejector-cooling system using ejector (EJC) is called CCRS. The COP of the CCRS is visibly higher than the single-stage refrigeration system. The analysis in this paper shows that the rational ejector-cooling condition will affect significantly on the improvement of the COP; When the ejector-cooling condition is definite, with the change of the temperature in the generator, there exists the optimum operating condition of the system; The system performance is obviously different with different refrigerant used. |
