Description
Dedicated outdoor air systems (DOAS) are first defined. Then the single-space operating system, whose performance is presented here, is shown to conform to that definition. The controlled components are identified, along with the minimal instrumentation needed for control. Control of each component individually, and in the context of the whole, is presented. Supplemental controls to reduce terminal reheat energy consumption in multi-space applications are developed. Issues surrounding the use of CO2-based demand-controlled ventilation, in light of ASHRAE Standard 62.1-2004 (former addendum 62n), are presented. Finally, experimental data are presented on the overall success of the DOAS design and control to provide air distribution and thermal comfort.
