【摘要】 通过对喷射式J-T制冷器的热力分析,推导出了制冷器预冷级与制冷级的流量比的理论最小值,可为此类制冷器的设计提供参考。用实例说明了制冷器流量比在制冷器设计中的重要作用。更多还原

【Abstract】 Based on the analysis of the thermodynamic process of the spray J-T cooler,the theoretical minimum ratio of the cooler′s flowrate has been derived.The minimum ratio of cooler′s flowrate can be guidance in the design of that type cooler.Some instances show that it is useful for the ratio of the cooler′s flowrate in the design of that type cooler.更多还原
