the hybrid cycle saved 24% to 40% electric energy compared to the conventional
cycle. Combining the hybrid system with an indirect evaporative cooler can bring
significant savings in energy consumption. The hybrid system saves more energy in
hot and dry climates than in hot and humid climates where more energy is consumed
than for the conventional cycle. The system can save energy when the air to be treated
has a higher sensible load fraction than latent load fraction. However, solar energy can
be combined to meet the higher latent load of the air. Enteria et al. (2011) presented
the combined desiccant-refrigerant air-conditioning system using the cyclic processes
