Ventilation effectiveness in a two-zone experimental cell.

Describes a study based on experimental work carried out in the full-size MiniBat experimental cell, comprising two zones separated by a wall and a door. Experiments were carried out in a steady state, under isothermal and non-isothermal conditions, with a heating system and a manikin. To determine ventilation effectiveness the tracer gas method was used. It was injected into zone 1 and two positions were examined. The study concluded that the heating system favoured the mixing of the air in the cell, which means that the ventilation effectiveness was always close to one. The manikin had an effect on temperature field stratification however, which is only noted in the manikin's absence. More differences were noted in isothermal conditions with disparities between the two zones.
