A novel targeted personalized ventilation system based on the shooting concept

The TPV provides air supply to the controlled area and thus improves the utilization ratio of the flow field. The air supply through the coupled tuyeres results in a uniform flow field with air speeds very close to 0.3 m/s. Compared with other PV systems, the velocity target value of the TPV system proposed in this paper is 40.5% lower, and the energy-saving rate reaches 52.9%. The effects of the TPVs were verified in a full-scale experiment.
