Abstract

The energy penalty is the main problem of the air conditioning system, so desiccant wheel (DW) is integrated with HVAC system to reduce the overall energy consumption, also DW extensively used for humidity control for various industrial and commercial processes. The aim of this paper is to construct and design a rotating DW to study its performance. The DW is filled with silica gel and has a cylindrical shape of 400 mm diameter and 110 mm thickness. The impact of different operational parameters such as the impact of regeneration temperature, flow rate and rota-tional speed on the performance of the wheel has been investigated. The temperature and humidity ratio at the outlet of DW are measured. The obtained results were used to calculate some parameters for the wheel such as the dehumidification effectiveness, the dehumidification coefficient of performance and the sensible energy ratio. It was found that the maximum dehumidification effectiveness occurs at regeneration temperature of 110 0C, rotational speed of 2rph and process air flow rate of 1.8 kg/min and maximum DCOP occurs at regeneration temperature of 65 0C, rotational speed of 2rph and process air flow rate of 2.4 kg/min
