FINDING OPTIMUM OPERATING CONDITION OF THE REGENERATOR

Developing energy systems using solar energy has emerged into the center of many research activities for the sake of energy conservation and environmental protection. In the area of air-conditioning engineering, the use of solar energy has also received a particular attention from researchers and practitioners. This study investigates the design and operation of a solar air-conditioning system, which mainly consists of four components: a regenerator, a total heat exchanger, a storage tank, and a sensible heat exchanger. The system examined in this study uses liquid desiccant for the dehumidification purpose as shown in Fig.1. A regenerator is closely related to the dehumidification process, and its performance is one of the most important features for such a system. Fig. 1. All year-round Air conditioning System using solar collector Proposed Absorption potential of desiccant solution significantly decreases after absorbing moisture from humid air, and it requires a significant amount of energy for the regenerator to recover absorption potential. In an effort to develop an energy-efficient regenerator, the regeneration process of the system under study uses hot air heated by solar radiation to recover absorption potential by evaporating moisture in desiccant solution.
