Firstly, a lower air demand would reduce the required dimensions of the ventilation system and therefore increase energy efficiency.
Dimensioning of dilution ventilation is often made using the perfect mixing approximation, assuming uniform contaminant concentration throughout the room space.
The modellers were provided with information such as the compartment dimensions and number/size of ventilation openings, the location and nature of the combustible items, and the details of the ignition source.
Basic information of the photocopy centers, including room dimensions, environmental conditions, business hours, types of ventilation, number of photocopiers, number of copies made on an average work day and the presence of other VOC-emitting sources were collected.
Several variants were examined: dimension of the horizontal opening, combination with other openings (of ventilation holes in the parts around the central space, and stairwell) and the effect of building materials used in the building fabric.
The particles are confined to room dimensions and in the real-data analysis also between heights of 0.5 1.5 m to reduce the effects of ventilation noise.
The lack of ventilation trapped the smoke and soot inside.
Only the lack of ventilation made her reconsider.
The heat and lack of ventilation really was the theme this year.
Adequacy of ventilation is a crucial part of mechanical ventilation.
Have some type of ventilation.
