Conception basée sur les contaminants à l'aide d'une modélisation multizone.

Multizone modelling approaches to contaminant-based design.

Auteurs : MUSSER A., PERSILY A. K.

Résumé

The paper discusses current design approaches and some possibilities for the future of contaminant-based design. Techniques and modelling approaches that could be used today are demonstrated using examples from a case study building. A multizone network airflow model is used to simulate airflow rates, pressure relationships, and contaminant transport. These simulations are utilized to specify minimum ventilation rates to control non-occupant-related contaminants for a system with carbon dioxide demand control. Contaminant build-up during an overnight shutdown is also studied, and strategies for a pre-occupancy purge are developed. The model is also used to size an exhaust fan to negatively pressurize an enclosure housing a biological process.
