摘　　要：针对单效NH3-H2O吸收式制冷循环性能低的缺点,对高效的GAX吸收式制冷循环进行了理论分析,得出了在冷凝温度(蒸发温度)一定时,系统的性能变化情况和系统性能随热源温度的变化情况,分析了系统内部换热器在回收设备间的回热、减少外部吸热量、提高性能系数中的作用,为进一步改进GAX循环性能提供了理论基础。In this paper,performances of the GAX cooling cycle are analyzed .The analysis shows that there is a higher coefficient of performance of GAX cycle than single cycle of NH_3-H_2O system .Change of system performance given condensation temperature or evaporation temperature is discussed .The effects of system internal heat exchangers including heat recovery?low heat absorption from heat source and high COP are analyzed .The analysis can be basis theory of performance improvement of GAX cycle.
