STUDY OF FOOD ODOUR CONCENTRATION AND DISPERSION IN AN ATRIUM

摘要

A computer modelling investigation was carried out to test three mechanical ventilation options for an office building with an atrium at its centre. The ventilation system is proposed to supply serviced air to the offices and the atrium and remove the food smell generated from a restaurant and its food area on the ground floor of the atrium. The options were assessed by the effectiveness of keeping odour concentration low on the two open plane offices on the two top floors. The objective of this study is to determine which of the three options of a proposed mechanical system would give the best ventilation. The paper reports the back-ground to a specific challenge, the design and modelling approach used and the outcome of the study.
