According to AHRI Standard 920, “DX - Dedicated Outdoor Air Systems (DOAS) condition outdoor ventilation air independently from the building HVAC system. This approach to handling ventilation air results in superior humidity control by limiting the primary source of humidity in most buildings – ambient humidity carried in by the ventilation air – directly at its source. When the DX-DOAS removes enough moisture from the ventilation air to match the building interior load, energy savings can be obtained by running the separate, sensible cooling only, interior cooling system at a higher evaporating
temperature, thus improving the energy efficiency.”
AAON can provide the DOAS unit and the sensible cooling unit. AAON units can be selected with different options to apply to an application.
