Curtains Air circulation type gate openings PROTECTION OF AUTOMOTIVE DOOR INDUSTRIAL BUILDING

摘要

The invention relates to the field of ventilation and is designed to protect automotive gate industrial premises from penetration of external cold air. The curtain airbag circulation type dampers to protect the gate opening automobile industrial premises contains a vertical suction duct having an air intake slit, vertical discharge duct, a suction line and the centrifugal fan. The pressure box comprises a rotary nozzle equipped with regulating rods made in the form of turnbuckles, with the possibility of regulation of the air volume in each nozzle, and the angle of attack of the air damper. Slit intake air suction duct is provided with an extension to hold the air downwardly at a predetermined angle of slide and is provided with a protective grille. As the working fluid in the formation of an air damper used cold air. A steerable nozzle may be in the form of segments. The discharge duct connected with the air suction pipe with a soft paste. The technical result - the efficiency of the air curtain with decreasing construction costs and a reduction of heat and electricity consumption. 4 NC PF 4 yl.
