Abstract
- Considering the unique thermal and load characteristics of underground store, a new DCV strategy has been established in this study. Combining the features of CO<subscript>2</subscript> control with conventional temperature control VAV system, this new system can achieve the PID control for both CO<subscript>2</subscript> and temperature, and a hand-off auto switch mode can be used to operate the system automatically. The system has been modeled by a dynamic simulation system, and a simulations for an existent underground store in Shanghai has been carried out. The results show that, comparing with the conventional CAV system and VAV system, about 22.2% and 17.5% of the annual energy consumption can be saved, respectively, which demonstrates that the DCV strategy is an acceptable technique to control thermal environment and indoor air quality simultaneously in underground stores.
