对一台四效溴化锂冷水机组进行了性能模拟，该冷水机组能够在最先进的双效循环基础上大幅提高性能。所研究的系统包括四个冷凝器和四个解吸塔，它们耦合在一起，形成了传统双效循环的延伸。根据之前的经验，在串联流上执行平行流系统，并采用双冷凝器耦合（DCC），从三效循环扩展到进一步提高性能。采用模块化吸收系统计算机模拟程序（ABSIM）对循环性能进行了研究。进行了模拟，以研究一些主要设计参数的影响。在设计点计算出的性能系数（COP）约为2.0（冷却），溶液出口处的热源温度为600华氏度（315摄氏度）- 温度解吸塔。通过对弱（泵送）溶液流速和四个解吸塔之间的溶液分离进行一些优化，COP可以提高到2.2以上。关键词:1995年，计算，性能，溴化锂，水，吸收式制冷，冷凝器，热流，传热系数，性能系数，制冷机:研讨会，ASHRAE Trans。1995年，第101卷，第一部分，论文编号CH-95-1-11525-527

Performance simulation has been conducted for a four-effect lithium bromide-water chiller capable of substantial performance improvement over state-of-the-art double-effect cycles. The system investigated includes four condensers and four desorbers coupled together, forming an extension of the conventional double-effect cycle. Based on prior experience, a parallel-flow system was performed over series flow, and double-condenser coupling (DCC) was employed, extending from triple-effect cycles to further improve performance. A modular computer code for simulation of absorption systems (ABSIM) was used to investigate the performance of the cycle. The simulation was carried out to investigate the influence of some major design parameters. A coefficient of performance (COP) of around 2.0 (cooling) was calculated at the design point, with a heat supply temperature of 600degF (315degC) at the solution outlet from the high-temperature desorber. With some optimisation of the weak (pumped) solution flow rate and of the solution split among the four desorbers, the COP may be raised above 2.2.KEYWORDS: year 1995, calculating, performance, lithium bromide, water, absorption refrigeration, condensers, heat flow, heat transfer coefficient, coefficient of performance, chillers
