Energy Efficient Liquid Desiccant Hybrid Air Conditioning System

Y. A. F. El-Samadony and B. M. Gibbs

Abstract—Desiccant systems are widely regarded as energy-saving alternatives to vapour-compression air-conditioning for handling the latent load. In the present work an energy efficient liquid desiccant hybrid air conditioning system is proposed with a novel liquid desiccant calcium chloride regeneration system. This regeneration is obtained by spraying fine liquid desiccant, calcium chloride, droplets into hot moist air. The effect of spray regeneration conditions, ambient conditions and space cooling load sensible heat factor on the performance of the proposed system was investigated. A comparison between the proposed liquid desiccant air conditioning system and the traditional one was studied. It was found that the values of the injected droplet diameter size, spray angle, hot air temperature, and spray injection speed, had an important role in the evaporation process. At RSHF= 0.6, the proposed system achieves 72% energy savings compared to a traditional air conditioning system.

Index Terms—Hybrid air conditioning system, liquid desiccant, calcium chloride, spray.
