In a liquid desiccant system, sufficient mass transfer is necessary in order to achieve proper dehumidification of water vapor in the air. One factor that can greatly affect air dehumidification is the structure of a gas-liquid contactor. This study investigates the effect of different structure of gas-liquid contactor on the dehumidification performance of a liquid desiccant system. In this system, lithium chloride solution was used as desiccant. By holding the air volume flow rate, the solution mass flow rate, and the volume of the gas-liquid contactor as constants, the dehumidification effect of different gas-liquid structures were clarified. It is found that gas-liquid contactor with length to height ratios greater than one can provide better dehumidification performance. The results from this study can be used for proper selection of gas-liquid contactor structure in liquid desiccant and hybrid liquid desiccant air conditioning system applications under cross flow configuration.
