吸收式制冷机在利用热能（如废热）生产用于建筑制冷应用的冷冻水方面具有良好的潜力。在本研究中，根据热力学第一定律和第二定律，对双效溴化锂/水（LiBr/H2O）吸收式制冷机的各种配置进行了分析和比较。这些吸收式制冷机包括平行流、串联流和双环流式系统。首先对这些系统进行了模拟，以研究第一定律性能，同时还计算了工质的性质、熵和火用，以检验不同操作条件下的第二定律效率。为了进行比较，还分析了单效吸收式制冷机的性能。单元:SICitation:研讨会论文，佐治亚州亚特兰大，2001年

Absorption chillers have good potential of employing thermal energy, such as waste heat, to produce chilled water for building cooling applications. In this study, various configurations of double-effect lithium bromide/water (LiBr/H2O) absorption chillers were analyzed and compared on the basis of the first and second laws of thermodynamics. These absorption chillers include parallel-flow, series-flow, and dual-loop flow type systems. Simulation of these systems was employed first to investigate the first law performances, while the properties, entropy, and exergy of the working fluids were also calculated to examine the second law efficiencies under different operating conditions. The performance of a single-effect absorption chiller was also analyzed for comparison purposes.Units: SI
