LoginThe contaminant efficiency of a ventilated ceiling used in kitchen has been determined as function of type of ventilation and air flow rate. The pollutant capture and containment efficiency can be 85-93 % using the concept of low velocity ceiling supply and centralised capture jet, and is as high as 98 % when combined with displacement ventilation at floor level.
