摘　　要：基于Aspen Plus软件建立溴化锂吸收式制冷系统模型,采用Eco⁃indicator16评价指标,综合22种环境影响类别,对溴化锂吸收式制冷系统进行生命周期评价。结果表明:溴化锂吸收式制冷系统在生命周期建造阶段、运输阶段、使用阶段和废弃阶段的EI16分别为1.93×10^(3)、4.00×10^(1)、9.18×10^(-1)和1.18×10^(2);系统建造阶段对环境造成的负面影响最为严重,其次为废弃阶段。Based on Aspen Plus software,a model of lithium bromide absorption refrigeration system was established,and Eco⁃indicator16 evaluation index and 22 environmental impact categories were used to evaluate the life cycle of the lithium bromide absorption refrigeration system.The results showed that the EI16 values of the lithium bromide absorption refrigeration system in the construction,transportation,use and disposal phases of the life cycle are 1.93×10^(3),4.00×10^(1),9.18×10^(-1)and 1.18×10^(2),respectively.The manufacturing phase of the system causes the most serious negative impact on the environment,followed by the disposal phase.
