Study of mass transfer in liquid desiccant for dehumidifiers packed by using conventional wooden slats

Abstract

Abstract To reduce electricity consumption, heating ventilation from the airconditioning sector focuses on developing alternative solution electrically-driven vapour-compression system. The liquid desiccant air-conditioning system represents energy efficiency. It is more environmentally friendly as an alternative technology for the dehumidification process, especially in cases with high latent loads to maintain air quality under reduced conditions for comfortable. This technology is more efficient than the vapour compression system in hot and humid climates like Indonesia. This study carries out an experimental investigation to find out how much moisture removal with using a liquid desiccant to absorb humidity in the air and to know general types of correlations for heat and mass transfer in the contactor for the air solution. In this experiment, liquid desiccant will be passed through wooden slats to determine the physical and thermophysical properties of the air. The general equation will be verified by the experimental results using a curve that fits this expected. The result is a decrease in the humidity in the air. It is known from the amount of moisture absorbed by the drying liquid, and the highest is 336.49 g / s and the lowest is 19 g / s. So it can be concluded that the drying liquid that is exposed to air and passing through wooden slats effective removes moisture.
