Abstract

Dehumidifier and regenerator is an important component in liquid desiccant air conditioning system. In the process dehumidification in dehumidifier, desiccant concentration decreased due to absorption of moisture from the air. To restore the concentration of desiccant used the regenerator for regeneration. The regeneration of desiccant concentration will be return to original state is accompanied by a rise in temperature and air humidity due to evaporation of the liquid desiccant. The research uses computational fluid dynamic simulation software (CFD) FLUENT 6.3 with desiccant flow rate variation from 0.01 to 0.05 kg / s at temperature 60 °C and the variation of the air with speed 5-13 m / s at temperature of 30-40 ° C. Simulations show, in the same time with a flow rate ratio between air and desiccant, mass transfer (the addition of desiccant to air humidity), the largest occur at air velocity 5 m / s and air temperature 40 ° C, humidification rate equal to the size of the mass flow rate.
