Ventilation & HVAC

CFD application : simulation of the heating and ventilation of a public building (school) for an analysis of comfort and air quality.

Air quality study in a public school

Background

  • Public building.

  • Comfort criteria to be respected.

  • Health criteria to be respected.

  • Key physics concepts : ventilation, thermal exchanges, particles tracking.
