The study reports a calculated performance of proposed desiccant air conditioning system, which is driven by air cycle refrigerator and evaporative cooler. The system has such characteristics that (i) safe material of air and water are used as a refrigerant, (ii) waste heat from air cycle refrigerator performs the regeneration of desiccant material for energy saving. The system can operate for wide range cooling load with a fraction control of evaporative cooling. This paper presents the influences of the ratio of air intake flow rate to the supply air for air conditioning room, and the temperature difference of heat exchanger on the system performance. The system performance drops with the increase of the ratio, and drops with the increase of temperature difference. Furthermore, it is found that the system of ventilation mode can not operate in the temperature difference of above 15 K.
