B5-08 Liquid Desiccant Air Conditioning System with Centralized Regenerator


In conventional air conditioning system for comfort or process application, chilled water is handled to a very low temperature in order to meet the dehumidifying demand. The (coefficient of performance) COP of the chiller is decreased. Liquid-desiccant air conditioners (LDACs) are important alternative to conventional equipment. They can dehumidify by absorbing moisture directly rather than by cooling the air below its dew point and at the same time, can improve the indoor air quality(IAQ). LDAC avoid CFCs and HCFCs by using nontoxic salt solution as the primary working fluid. In this paper, A simple style of LDAC with a centralized regenerator is introduced. Simple performance analysis was performed with consideration of different out door air conditions.
