AB - This paper presents real time performance analysis of a silica gel based  desiccant wheel dehumidifier. Thermodynamic model is also validated through  comparison under a wide range of operating conditions for subtropical climate  conditions. Initially, a mathematical model is developed by using various set  of equations for desiccant wheel dehumidifier in Engineering Equation Solver  (EES). Afterwards, a parametric analysis of the system is performed including  various design and climate parameters such as: inlet air humidity ratio,  inlet air temperature, regeneration inlet humidity ratio, regeneration  temperature, and rotation speed of the wheel. Then, an experimental setup of  the system is established in Taxila Pakistan for the real-time performance  assessment. The results revealed that the optimal rotation speed of desiccant  wheel ranged from 15-17 rph. The maximum model based and experimental  effectiveness is 0.45 and 0.43, respectively at regeneration temperature of  80°C. The maximum and minimum root mean square error (RMSE) values for  effectiveness are 3.2% and 2.1%, respectively. Thus, the comparison between  experimental and model results showed a good agreement.
