Displacement Ventilation

Price PTU 2008

• Outdoor Air requirements (ASHRAE Standard 62-2004) – Requirement =

(Occupant/Space Requirement)/(Ez)

– OHAD = 100/1.0 = 100 CFM – DV = 100/1.2 = 80 CFM

• 20% Savings on OA requirements

Ventilation Effectiveness

Source ASHRAE

DV Characteristics

• Measure of Contaminants in Occupied Zone compared to Return Air

• Mixed Systems < 1.0 • DV Systems > 1.0 • Potential Reduction for

outdoor air requirement under ASHRAE 62-2004

DV Characteristics

• New research into Healthcare and DV – Show applications in patient rooms, waiting areas, admittance, non-

critical care spaces • Superior comfort levels • Improved contaminant removal

– Significant reduction in infectious transmission through airborne containments
