Absorption systems have considerable potential to fight global warming and help transition to renewable energies. These machines use multifunctional exchangers (heat and mass transfer), which have been pointed out as the “bottleneck” in the performance of such systems, especially the absorber. The present review offers an up-to-date overview of the different exchanger technologies that have been studied and tested for small-capacity single-stage continuous absorption chillers operating on binary working fluids. The review focuses more particularly on the experimental studies of innovative exchanger technologies with conventional or special geometries, with or without mechanical treatments, tested on the three most experimented working pairs (NH3-H2O, H2O-LiBr, and NH3-LiNO3). The use of chemical treatments is not covered. The main objective is to provide information to improve our understanding of how the exchanger technologies used in the mentioned systems have evolved over the past 40 years as well as the advantages and disadvantages for their different uses.

吸收系统具有抗击全球变暖并帮助向可再生能源过渡的巨大潜力。这些机器使用多功能交换器（传热和传质），这些交换器已被指出是此类系统（特别是吸收器）性能的“瓶颈”。本综述提供了已针对在二元工作流体上运行的小容量单级连续吸收式制冷机进行研究和测试的不同交换器技术的最新概述。这篇综述更侧重于对具有常规或特殊几何形状，经过或不经过机械处理的创新交换器技术的实验研究，并在三个实验最多的工作对（NH3-H2O，H2O-LiBr和NH3-LiNO3）上进行了测试。不包括化学处理的使用。
