Description
<p>This paper presents experimental data of heat and mass transfer characteristics of the gas-liquid contactor for a liquid desiccant air-conditioning system. In this study, finned-tube type internally heated regenerator is newly proposed. Furthermore, aqueous solution of ionic liquid is used as absorbent solution. Heat and mass transfer characteristics of the combination of proposed finned-tube type gas-liquid contactor and ionic liquid have yet to be revealed. Effects of air side Reynolds number and solution film Reynolds number upon air side heat transfer coefficient, solution side mass transfer coefficients and air side friction factor are experimentally investigated, and also, in order to obtain these data, numerical simulations are conducted. As a result, experimental data of these transfer coefficients and friction factor were obtained and the relationship between transfer coefficients and Reynolds numbers are quantitatively revealed. Moreover, these experimental results revealed that the mass transfer in the solution falling film is more dominant than that in the air side in almost entire experimental conditions.</p>
