Direct air capture (DAC) has been explored mostly at centralized and dedicated capture facility. This ongoing work is focusing on investigating potentials of DAC coupled with heating, ventilation, and aircondition (HVAC) system in buildings in a more distributed way. A preliminary simulation-based case study of a desiccant-assisted dedicated outdoor air system (DOAS) with a DAC is conducted in six locations in the U.S. Results show that the CO2 capturing potential and the DAC regeneration energy at the humid locations are relatively larger.
