Dedicated Outdoor Air Systems

A dedicated outdoor air system (DOAS) is a unit supplying cooled, dehumidified outside air to the building in summer and heated outside air in the winter. The system can also include a total energy wheel. An energy recovery wheel offers up to 80% total effectiveness reducing the heating and cooling capacity requirement of the DOAS unit significantly.
