This study introduced dew point cooling system based on Maisotsenko Cycle Air-Conditioning (MAC/M-Cycle) for hot and humid climate. The purpose of this study to analyze the air thermodynamic properties and conditions supplied to the conditioned space. The room model has been developed to investigate the dry bulb temperature, specific humidity, and velocity distribution in the room. The simulation results showed a significance difference cooling capacity between these two systems. Consequently, this integrated system can realize significant energy saving and indoor air quality.
