This research was concerned with the enhancement of heat transfer by surfactant added to the aqueous solution of LiBr. Different vertical tubes were tested with and without an additive of normal octyl alcohol. The test tubes are a bare inner surface, a groove inner surface, a corrugated inner surface and a spring inserted inner surface tubes, The additive concentration was about 0,08 mass%. The heat transfer coefficient was measured as a function of the film Reynolds number in the range of 2 0~200. Experiments were carried out at higher cooling water temperature of 35℃ to simulate an air cooling condition for several kinds of absorber testing tubes, The experimental results were compared with and without surfactant. The enhancement of heat transfer by Marangoni convection effect which was generated by addition of the surfactant is observed in each test tube. Especially. it is clarified that the tube with an inserted spring has the highest enhancement effect.
