Preconditioned outside air system
Dedicated outdoor air system allows for flexible building design with selectable airflow rates between 1200 to 2000 cfm.
LG's dedicated outdoor air system (DOAS) is designed to combine preconditioned outside air with variable refrigerant flow (VRF) systems to improve indoor air quality. It allows for flexible building design with selectable airflow rates between 1200 to 2000 cfm, space-efficient reheat coils that can reheat without adding extra bulk, and easy integration with building automation systems. DOAS can precondition and reheat spaces with recovered waste heat from other parts of the building. This allows for it to be fully integrated with a modern VRF system and meet energy standards.
