Theoretical and Experimental Analysis of Desiccant Wheel Performance for Solar Hybrid Desiccant Air-Conditioning System

Article Preview

Abstract:

Dehumidification is considered as a key feature of HVAC systems for thermal comfort. Malaysia is located in the South East Asia region which has a sufficiently high temperature and humidity of approximately 80% RH. This requires a process which can reduce moisture in the air. Desiccant wheel is used to provide dehumidification. Desiccant wheel with model no. 770 WSG produced by NOVELAIRE having operating system 1:1 and maximum flow rate of 1500 cfm has been theoretically and experimentally analyzed for its performance. The results show good matching between theoretical and experimental results in term of sensible and latent effectiveness of dehumidification process as well as regeneration process. This desiccant wheel is capable of condensing water at 0.05kgH2O/s and providing 3.3639 kW load reduction. With this significant load reduction, the component integrated in solar hybrid desiccant air-conditioning system can perform comfort cooling to area with high latent load such as hall, hyper market and commercial building.
