An experimental study of the absorption process of water vapor into a lithium bromide solution film was performed. The lithium bromide solution is circulated between the absorber and the generator vessel. The absorber is a chrome-plated brass tube of 84 mm outer diameter and 400 mm length. The solution is fed from the annular slit at the top of the pipe. After absorbing water vapor, the weak solution is fed to the genetor for the recovery of concentration. The generated vapor is provided to the absorber vessel, and the enriched solution is then returned to the absorber. The absorbed water, which is measured as the vapor flow rate by a rotameter is plotted against cooling water temperature while keeping film thickness, inlet temperature and concentration constant. They are compared with the theoretical results by the method proposed previously. Although the experimental values are somewhat lower at 5 Torr, they showed good agreement with the theoretical ones.
