| Resumen |
This report reviews current methods of evaluating the effectiveness of the ventilation of enclosures. British Standard BS 5925 which describes a method for calculating air change rates was applied to two enclosures where the air change rate was measured experimentally. In the first of the two cases considered, the calculated air change rate was in good agreement with the measurements, whereas in the other case it under-predicted the ventilation rate. An improved model was proposed and validated against 29 experimental tests carried out in a purpose built enclosure. The experimental tests consisted of releases of simulated methane gas for a range of leak rates and ventilation rates. Findings are discussed. |
