Title Ventilation of the working zone of industrial halls by stabilised air currents

Abstract Description of available industrial ventilation systems and their shortcomings. For good distribution of air temperature and reduced airborne contaminant concentrations, the mode of air supply is of importance. It is proposed to supply air by large vertical cylindrical inlets situated in the working zone. If the supplied air is ~2K lower in temperature than the air in the zone, a stabilised air flow is produced which ventilates the work zone with clean supplied air and ejects emissions into upper levels of the zone, whence it is exhausted. A good air speed at the inlet is 0.5m/s.
