One of the commonly used ventilation parameters is ventilation effectiveness, and it shows how certain regions in the room are influenced by contaminant sources introduced into the room. Three definitions of ventilation effectiveness are often used, namely, the ventilation effectiveness in the occupied zone the local ventilation index and the mean ventilation effectiveness They are defined as...

Ventilation effectiveness The ability of a ventilation system to remove the pollution generated within a space. 

The real-time monitoring of some species concentration distribution in indoor air is an effective way to evaluate the dispersion of fresh air and/or gas-phase chemical pollutants, for example when determining the ventilation effectiveness, the air exchange rate (ACH) or the air age distribution for a given space (Park et al., 1998 Shin et al., 2005). It also provides a helpful validation for transient... 

I40C Consider a house whose attic space is ventilated effectively so that the air temperature in the attic is the same as Ihe ambient air lempeiaiure at all times. Will the roof still have any effect on heat transfer through the ceiling Explain. 

Gas flows through the SE will be different ( ventilation effect) and will depend on how the oxide SE was applied on the surface of YSZ and how it was heat-treated and sintered afterwards. The vast majority of the modem technologies will allow creating a uniform thickness of SEs (REs). However, the stmctural orientation of an oxide SE and, especially, its surface and bulk porosity will change from one technology to another and from one sintering temperature to another [9]. This fact, in turn, will influence characteristics of the YSZ-based sensor, such as sensitivity, reproducibility of measurements, response and recovery time, and so on. Let s indicate both necessary and sufficient conditions of existence of such a ventilation effect within the SE.

ASHRAE 62, Ventilation for Acceptable Air Quality This standard can assist professionals in the proper design of building ventilation systems. Important aspects of the standard include the definition of acceptable air quality and information about ventilation effectiveness. It makes a recommendation about using source control through isolation and local exhaust. The standard also contains information on the use of heat recovery ventilation and provides a guideline for allowable carbon dioxide levels.

The samples analysed for the investigation of ventilation effect were taken from position C corresponding to material temperatures between 980°C and 1010°C (see Fig. 23.4). The frequency of minimum scale thickness was obtained by subdividing the BSE images into sections of 2.2 pm widths and determination of the minimal scale thickness of the Cr203 layer for each... 

Early toxic respiratory failure will usually be type 2 (low PaOa and high PaCOa) and adequate ventilation will reverse this situation quickly. If end-tidal CO2 monitoring is available, this will be a valuable indicator of ventilation effectiveness...
