| Abstract | 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 |
