溴化锂吸收机大约在1940年首次商业化。在所有上市的设计中，吸收塔/冷凝器的热量通过管壳式换热器从循环中排出，进入循环水，然后通过冷却塔与环境空气接触进行处理。在机械制冷技术中，蒸发冷凝产品已成为带有独立冷却塔的水冷式冷凝器的可用替代品。溴化锂机还没有这种替代品，主要是因为难以通过一个共同的表面配置来管理内部和外部的传热过程，以满足所有的需求。 本文的重点是开发一种直接蒸发冷却吸收/冷凝器。在过去或目前市场上可用的硬件中已经展示的冷却器的其他功能将不在本讨论的范围内。第二个目标是确定蒸发冷却对主动太阳能冷却设备的重要性，尤其是作为太阳能冷却设备散热方式的干空气冷却的替代方案。引文:德克萨斯州休斯顿ASHRAE学报第88卷第1部分研讨会

Lithium bromide absorption machines first appeared commercially circa 1940. In all designs marketed, absorber/condenser heat has been rejected from the cycle through shell-and-tube exchangers to circulating water that is then processed in contact with the ambient air through a cooling tower. In mechanical refrigeration technology, evaporative condensing products have been an available alternative to water-cooled condensers with separate cooling towers. Lithium bromide machines have not been available with this alternative, mainly because of the difficulty of managing internal and external heat transfer processes through a common surface configuration that would meet all the needs satisfactorily. The main focus of this paper is the development of a direct, evaporatively cooled absorber/ condenser. Other features of the chiller already displayed in the past or presently available hardware on the market will not be a part of this discussion. A second objective is to establish the significance of evaporative cooling for active solar-cooling devices and, in particular, as an alternative to dry-air cooling as the means of heat rejection for solarcooling equipment.
