摘　　要：压缩-喷射二级制冷系统的COP较传统的喷射制冷系统的COP提高了20%～50%。本文分析了发生温度、中间温度、冷凝温度、蒸发温度对以太阳能为热源的压缩-喷射二级制冷系统的运行工况的影响。结果表明,在综合考虑技术和经济的前提下,应尽可能地提高系统运行的发生温度,降低冷凝温度,中间温度的选择应兼顾集热器的面积和系统的性能系数。Coefficient of performance of compression-ejector double-stage refrigeration system was improved 20% -50% than that of ejector refrigeration system. This article analyzed the effects of the temperature on this new system. The result shows that when technological and economic factors are considered, generator temperature should be raised, but on the other hand condenser temperature should be reduced as far as possible. The choice of intercooler temperature should consider both the area of solar collector and coefficient of performance of the double-stage refrigeration system.
