中间注液制冷系统中注液量对COP影响的研究

Study on COP of Medial Liquid Injection Refrigerating System under Different Quantities of Medial Liquid Injection

在分析中间注液冷却循环制冷系统性能指标的基础上,研究了中间注液量对循环系统COP的影响。结果表明:中间注液冷却循环系统可以明显降低压缩机的终温,改善循环的运行条件;中间注液量的多少除对压缩机终温有影响外,还对系统的COP有直接影响,而且与所采用的工质有关。

On the basis of analyzing performance index of refrigerating system of medial liquid inject cooling cycle, this paper studies on inflance of quantity of medial liquid injection on COP of circulating system. The result shows: circulating cooling system of medial liquid injection can put down obviously compressor-discharge temperature and improve operation condition of the circulation: quantity of medial liquid injection also has direct influence on COP of the system beside it has influence on compressor-discharge temperature, which relates to adopted working medium.
