"We're providing for increased outside air because the ventilation effectiveness
is higher, so we're able to provide 30 percent more outside air to keep our C[O.sub.2] levels down.
Ventilation arms (pictured) remove air contaminants while an enthalpy wheel provides exhaust air heat recovery, the latter of which has improved heating and ventilation effectiveness
by roughly 70 percent.
as an indicator of occupant exposure to particles from indoor sources.
Increased ventilation rate does not always result in better ventilation effectiveness
when using warm air heating.
W Assessing the ventilation effectiveness
of naturally ventilated livestock buildings under wind dominant conditions using computational fluid dynamics.
REHVA Guidebook, Ventilation effectiveness
. Brussels: REHVA.
is maximized, particularly for perimeter rooms in cooling-dominated climates, by Type A ceiling-mounted, horizontal-throw diffusers, with maximum throw reaching the far wall and with exhaust registers.
It was found that the use of a secondary PV system in conjunction with a primary air-conditioning system in a hot and humid climate can efficiently enhance thermal comfort and improve the ventilation effectiveness
at the immediate breathing zone by up to 50% more than can be obtained with mixing ventilation (MV) alone (Sekhar et al.
Paragraph 0.26 states that Ventilation effectiveness
is a measure of how well a ventilation system works in terms of delivering the supply air to the occupants of a building.
Ventilation efficiency is the term used to quantify ventilation effectiveness
, being a measure of the ability of a ventilation system to exhaust the pollutants generated within a space.
Using displacement ventilation increases the ventilation effectiveness
and, thus, improves the IAQ for a specific air change rate compared with mixing ventilation.
