A NEW MODEL TO COMPUTE AIR DISTRIBUTION.

Author(s) : PELLETRET R., KHODR H.

Summary

IN THERMAL SIMULATION CODES FOR BUILDINGS, AERAULIC TRANSFERS ARE COMPUTED EITHER WITH VERY SIMPLIFIED MODELS (FIXED AIR DISTRIBUTION) OR WITH SOPHISTICATED MODELS (BASED ON THE COMPUTATION OF THE PRESSURE FIELDS). THE SIMPLIFIED MODELS ARE NOT ACCURATE ENOUGH AND THE SOPHISTICATED MODELS ARE TOO COMPLICATED. AN INTERMEDIATE MODEL HAS BEEN DEVELOPED. THIS NEW MODEL IS BASED ON THE COMPUTATION OF THE TEMPERATURE FIELDS AND ON THE KNOWLEDGE OF AN AVERAGE AIR DISTRIBUTION DUE TO AIR LEAKAGE AND SPECIFIC VENTILATION. SO, AS THIS MODEL NEEDS NO COMPUTATION OF THE PRESSURE FIELDS, IT IS WELL ADAPTED TO THERMAL SIMULATION CODES. THE NEW MODEL HAS BEEN VALIDATED ON A REAL SCALE EXPERIMENT. DETAILS ARE GIVEN ON THE VALIDATION ASPECTS.
