Experimental Exploration on Performance Advancement of Solid Desiccant Dehumidifier

The foremost idea of this current effort is to study the performance parameters of silica gel based desiccant dehumidifier and optimize its performance on the basis of Process air inlet velocities and air inlet temperatures. Desiccant dehumidifier considered in this work is coupled with the VCRS system. This Analysis is carried out for hot and humid conditions at four different air velocities (i.e. 2.8, 3.5, 4.5, 5.2 m/s) and different ambient temperatures (i.e. 32, 33, 34, 35°C). Regeneration rate and adsorption rate at different air flow rates and at different ambient temperatures is analysed. Regeneration is occurring through an electric heater fitted in the regeneration sector. Thermal factors, for instance temperature (dry bulb) and relative dampness are measured to enhance performance parameters like Adsorption rate, latent COP, Regeneration rate and Effectiveness of desiccant of wheel. Revamp values of this parameters are obtained at 3.5 m/s entering velocity of process air and 34°C ambient temperature which results in better performance of desiccant dehumidifier with less energy utilization for the conditioned space.
