摘要：

The objectives of this study were to evaluate the performance of a novel two-stage rotary desiccant cooling (TSRDC) system and to obtain useful data and experiences for practical application. Newly developed compound desiccant (silica gel-haloids) was adopted in the system. An experimental set-up was built and used to test the system performance under three typical environmental conditions. System performances were evaluated in terms of moisture removal D and thermal coefficient of performance COPth. It has found that the required regeneration temperature of TSRDC system is low and CoPth of the system is high. Regeneration temperatures from 65 degrees C to 80 degrees C, 65 degrees C to 75 degrees C and 80 degrees C to 90 degrees C were recommended for each environmental condition. In addition, the effects of some important operating parameters, such as inlet temperature and humidity ratio of process and regeneration air, on system performance were also investigated in this study.
