Abstract Full text About this article

The paper deals with a numerical multi-physical investigation on performance assured by different ventilating systems in supplying air quality and comfort conditions in a movie theatre hall. Mixing air distribution, under floor displacement and personalized air distribution systems are outlined in a given geometry. Momentum, energy and mass conservation equations are solved in order to highlight velocity fields, temperature distributions and carbon dioxide levels in each condition. Effectiveness of ventilation and mean age of air supplied to spectators are also computed giving further evaluation parameters in order to strike a balance between strong and weak points characterizing the studied systems.

Abstract

The paper deals with a numerical multi-physical investigation on performance assured by different ventilating systems in supplying air quality and comfort conditions in a movie theatre hall. Mixing air distribution, under floor displacement and personalized air distribution systems are outlined in a given geometry. Momentum, energy and mass conservation equations are solved in order to highlight velocity fields, temperature distributions and carbon dioxide levels in each condition. Effectiveness of ventilation and mean age of air supplied to spectators are also computed giving further evaluation parameters in order to strike a balance between strong and weak points characterizing the studied systems.
