Abstract
In this study, heat and mass transfer characteristics of live components solution (LiBr+LiI+LiN0₃+LiCI+H₂ O) which could be substituted for commonly used LiBr solution are tested using a helical absorber. The arrangement of helical-typed heat exchangers allows to make the system more compact as compared to conventional one. The effects of experimental parameters, such as the solution flow rate, cooling water, solution temperature, solution concentration and surfactant have been investigated in view of the heat and mass transfer. The results of the experiment of heat and mass transfer perfomlance show that live components solution should have 2% higher concentration for equal absorption capacity of LiBr solution. But considering that five components solution have higher solubility than LiBr solution about 4% high concentration, five components solution could be applied to a small sized water cooled or air cooled absorption chiller/heater. The increase of heat and mass transfer coefficient by surfactant addition is about 25 ~ 30% and 23 ~ 40% respectively.<br/>
