Abstract
Dedicated outdoor air systems (DOAS) are proved to be beneficial in many practices. However, not all DOAS configurations under different climates promise the same benefits. This paper presents a simulation study on evaluating various energy savings benefits of different DOAS configurations among diverse climate zones in the United States. Three DOAS configurations in a commercial building are simulated in this study: (1) fan-coil units (FCUs) as terminal unit with a DOAS unit which supplies conditioned outdoor air (OA) directly to each occupied space; (2) FCUs with a DOAS unit which supplies conditioned OA to the FCUs; and (3) a DOAS with active chilled beams. Simulation results indicated that DOAS energy savings ranged from 7.69% to 31.92%, as compared to simulated baseline. Suggestions were given with this study: a designer should consider supplying the conditioned OA directly to each occupied space with a DOAS, and employing active chilled beams as the local terminal HVAC units when it is possible.
