| Abstract | ||||
| In the present work, experimental investigation of the performance of double bed desiccant dehumidification system has been carried out. The two desiccant beds operate simultaneously. When one of the two beds functions as an adsorber, the second operates as a regenerator. In this investigation, silica gel is applied as the desiccant material. Hot air from an air heater is blown through the regenerated bed using an air blower. System performance at different conditions of flowing air is demonstrated. The experimental tests were carried out at different conditions of inlet air and initial bed parameters. Temperature and humidity of air at the inlet and exit of the bed were measured. The effect of adsorption to desorption air mass ratio is examined. In the present study, it is found that 63% regeneration to total air mass ratio is the optimum value. | ||||
