由于蒸汽压缩系统对电能的高要求，吸收系统是蒸汽压缩系统的替代品。研究人员正致力于改善吸收系统的性能，其中一种可能的方法是使用（火用）方法分析吸收系统每个部件的不同损失。本文对单效溴化锂/水吸收式制冷机系统进行了能量和火用分析。开发了一个用于系统参数研究的计算机仿真模型，该模型还分析了发电机温度对系统不同部件（火用）损失的影响。 与系统中涉及的其他组件相比，发电机中的不可逆率最高。对于给定的一组运行参数，性能系数（COP）在0.85–0.93之间。引文:ASHRAE交易——第120卷第2部分，华盛顿州西雅图

Absorption systems are an alternative to vapor compression systems due to the high requirements of electrical energy involved in the vapor compression systems. Researchers are concentrating to improve the performance of absorptions systems, and one of the possible ways is to analyze different losses associated in each component of an absorption system using an exergy approach. In this paper, energy and exergy analysis of the single-effect lithium bromide/water absorption chiller system has been carried out. A computer-based simulation model has been developed for parametric investigation of the system which also analyses the effect of generator temperature on the exergy losses in different components of the system. The irreversibility rate in thegeneratorhasbeenfoundtobethe highest when compared with the other components involved in the system. The coefficient of performance (COP) is found to be in the range of 0.85–0.93 for a given set of operations parameters.
