对溴化锂溶液中水蒸气的吸收过程进行了实验研究。为了开发以溴化锂溶液为工作流体的高性能吸收式制冷机/加热器，提高四种换热器中传热面积最大的吸收体的性能是最有效的方法。本文研究了吸收式制冷机/加热器吸收器的裸管、碰撞裸管、花管和扭曲花管。花管和扭曲花管的传热传质性能比通常用于吸收器的裸管高约40%。因此，花管和扭曲花管有望实现高的传热传质性能。©1999 Scripta Technica, Heat Trans Asian Res, 28(8): 664-674, 1999
An experimental study of the absorption process of water vapor into a lithium bromide solution was performed. For the purpose of the development of a high-performance absorption chiller/heater utilizing a lithium bromide solution as the working fluid, it is the most effective way to improve the performance of the absorber with the largest heat transfer area of the four heat exchangers. This paper considers a bare tube, bumping bare tube, floral tube, and twisted floral tube for the absorber of an absorption chiller/heater. The floral and twisted floral tubes have about 40% higher heat and mass transfer performance than the bare tube conventionally used in an absorber. Therefore, floral and twisted floral tubes are expected to realize high heat and mass transfer performance. © 1999 Scripta Technica, Heat Trans Asian Res, 28(8): 664–674, 1999
