What does DOA stand for?

Chiller and dedicated outdoor air system (DOAS) subsystem models and methods of simultaneously solving the component states and control actions needed to satisfy loads under any given condition with minimal input energy are presented.

These new technologies include: * dedicated outdoor air systems * lower coil and discharge air temperatures * ECM motors The ECM motors were a later addition to the research program.

Fortunately, the growing acceptance of a new HVAC design known as a dedicated outdoor air system (DOAS) promises to improve indoor air quality and comfort while lowering operating costs.

INTRODUCTION Dedicated outdoor air systems (DOAS) (Mumma 2001), when used, are generally required to employ total energy recovery, or an enthalpy wheel (EW), by ANSI/ASHRAE/IESNA Standard 90.

The air distribution systems reviewed include an SCTF system with independent "ventilation" and "thermal cooling" on zone-based demand, a personalized ventilation system coupled with secondary ambient air distribution system, a displacement ventilation system, an underfloor air distribution system, and a dedicated outdoor air system coupled with radiant chilled ceiling.
