Personalized air terminal device

Summary

The issues of developing the methods of designing air exchange in civil building premises are considered. These methods are related to the introduction of innovative air terminal devices in practical design of ventilation systems. The analysis of the efficiency of air exchange arrangement in the premises of civil buildings with the use of traditional ventilation systems was carried out. The conclusion was drawn about the necessity of designing an innovative air terminal that provided for spot cooling of the workplaces with rapidly damping micro jets. The basic configuration is presented of the designed personalized air terminal device based on a textile insert with microholes (0.2–0.6 mm diameter) that will allow supplying inlet air by low-pulse micro jets into the human breathing zone. The advantage of the designed device is in the possibility of supplying the required air amount into the human breathing zone. This will provide for the regulatory and comfortable parameters of the microclimate. The introduction of the personalized air terminal device allows improving the efficiency and cost effectiveness of the ventilation system.
