Scale model studies on the ventilation of poultry farm houses. Modellkiserletek ketreces baromfitarto epuletek szelloztetesenek javitasara.

Characteristics of the ventilation in poultry buildings have been studied at the Hungarian Institute for Building Science. The pressure loss of the cross-building ventilation flow is determined for a section of a typical building and for two typical air inlet-outlet layouts. On the basis of velocity measurements the local hourly air change rates were determined in the cages and compared to the general air change rate in the building.
