Abstract
The study develops exergy analysis of the desiccant dehumidification augmented air conditioning systems. The air cooling system is absorption or vapor compression cooling system. The performance of systems is evaluated for varied ambient condition. The calculation results are described on psychrometric chart. The results show system performance, which depends on out-door condition, mainly in hot-humid climates and on system operation modes. The performance of the systems for the East Asian regions and Tokyo in Japan is also evaluated. The desiccant dehumidification-absorption hybrid air conditioning system has a high potential of energy saving. The desiccant hybrid system has exergy loss reduction or exergy efficiency improvement and coefficient of performance for hot and humid climate regions.
