A novel air handling method, the heat-humidity segment handling method, is proposed for overcoming the shortcomings of the present air handling method in air-condition system. The principle and process of this method are analyzed, and its investigation model for energy-saving is developed as well. The influence of cooler configuration and return-air state on the energy-saving effects is given. Applying this new method, the results show that compared to present method, the COP (coefficient of performance) can be enhanced by more than 9. 14% when the set cooler temperature difference is 7 ℃ and the outlet air temperature is 16 ℃; the COP can be enhanced by more than 8% when the dry bulb temperature and wet bulb temperature is 25 ℃ and 21 ℃ respectively.
