  • Abstract This thesis is aimed to study the heat and mass transfer performance of a generator for the absorption cooling system. Both aqueous lithium bromide (LiBr) and lithium chloride (LiCl) solutions are studied. The generator inlet concentration and outlet concentration are set to 55% and 60%, respectively, for aqueous lithium bromide solution, and 40% and 45%, respectively, for aqueous lithium chloride solution. Therefore, the system of falling film desorption process is studied for the simulation of the generator.
         A finite-difference method is applied to numerically simulate the heat and mass transfer for a falling film desorption process in the generator. Parameters effects the inlet temperature, the heat source (wall) temperature, and the vapor pressure consistent with the saturation pressure of the condenser, and the solution flow rate are studied.
        The results of the present study provide important design references for absorption cooling systems.
