Abstract
The performance of “ductless” personalized ventilation in conjunction with displacement ventilation with regard to exposure to different body bioeffluents was studied. Experiments were performed in a full-scale room furnished as a double office. Room air temperature was kept at 26 oC. Two breathing thermal manikins were used to simulate occupants. Tracer gases were used to simulate human bioeffluents (feet, groins, armpits and exhaled air) released from one manikin, simulating polluting occupant. The second manikin simulated exposed occupant. Different combinations of supply flow rates and operation modes for the ductless personalized and displacement ventilation were tested. The location of the bioeffluent source affected the spread of body bioeffluents in the space. The ductless personalized ventilation provided cleaner air to both occupants than displacement ventilation alone. Occupants using the ”ductless” system will perceive the supplied air quality as superior compared to displacement ventilation alone.
