THEORETICAL ANALYSIS AND EXPERIMENT OF AIR INFILTR

Air infiltration caused by natural ventilation if analyzed in this paper with focus on the synthetic effect of thermal pressure, wind pressure and diffusion .A series of tests were made in an office building to study the relationship of above three factors effecting air infiltration. Formulas of air infiltration prediction had been derived based on both theoretical analysis and experimental data. The actions of the factors effecting air infiltration rate were discussed.
