This study develops knowledge of the methodological
analysis of indoor air distribution in high density
rooms, allowing evaluation of the expected comfort
level of the occupants. A typical classroom is presented
as a case study, focusing on the influence of dedicated
ventilation. The methodology established the boundary
conditions using discretization and determination of
values over time which defined the dynamic energy
behaviour of the room, by means of a nodal model.
The study incorporates sectional isothermal curves and
air velocity analysis, the use of indicators to evaluate
the thermal comfort of the occupants according to
ASHRAE standards, and comparisons of alternative
HVAC systems.
A case study application shows poor efficiency of
traditional radiator heating systems versus those which
incorporate a neutral ventilation air supply
