Effect of Taiwan Ambient Conditions on Hybrid Solid Desiccant Vapor-Compression Air-Conditioning System

摘要

Solid desiccant cooling system is considered as alternative to the typical air conditioning system which consume lot of energy. The latent and sensible loads are handled separately and more effectively in desiccant wheel and cooling coil. In this paper, performance of typical solid desiccant system has been analyzed and compared with hybrid solid desiccant vapor compression air-conditioning system. Hybrid desiccant system use waste heat from condenser for regeneration process at desiccant wheel to removes the moisture at desiccant material. This system has been analyzed at typical hot and humid weather of Taichung, Taiwan. The results show that hybrid desiccant cooling system has 5.3% higher COP than typical cooling system. Higher outdoor temperature and humidity ratio leads to a better desiccant cooling performance. These results confirm that hybrid desiccant cooling system is feasible for hot and humid weather conditions in Taiwan.
