A series of CFD and model experiments were carried out in order to find the most effective ventilation system in a separated refuse disposal facility. The ventilation system needed in the facility protects the working space from dust and odors generated by handling refuse. The desired ventilation system is to introduce the outdoor air from the one side of the working area and to exhausts the contaminated air through the opposite side of the refuse stock yard, so-called the unidirectional airflow ventilation. Both of the experiments indicated that an air curtain system and a wind shield screen which were added to the basic system could improve the ventilation efficiency. System performance was measured at a newly built facility. The measurements proved that this system needs only an additional 3% of total flow rate to effectively protect the working space from contamination.
