Abstract

1,027,506. Air curtains. R. J. FLEBU. Feb. 5, 1963 [Feb. 9, 1962], No. 4676/63. Heading F4V. A door opening 2 in a wall 1 is provided with an air curtain formed by air projected from openings 9-14 in distribution ducts 3-8 located on either side of the door opening and supplied with air at different temperatures. As illustrated, the distribution ducts are located on the outside of a wall separating a warm room from the outside air and ducts 3 and 6 are supplied with heated air, ducts 5 and 8 with unheated air and ducts 4 and 7 with air at an intermediate temperature. A centrifugal blower is located on each side of and above the door opening and has a rotor 17 drawing air through ducts 21 and 22 whose inlet openings are located above the unheated and heated parts of the air curtain respectively. The duct 22 includes a heater 23. The blower rotor 17 has a central circular partition wall 18 aligned with a partition wall 25 extending from the blower to the inlet of the distribution duct 7 so that the duct 7 is supplied with a mixture of heated and unheated air and the ducts 6 and 8 with heated and unheated air respectively. The ducts 3-8 may be turned to vary the direction of the air streams. In a modification (not shown), distribution ducts may be arranged along the upper edge of the door opening. Also the curtain may be used to separate cold rooms from the warmer outside air or to separate two rooms of a building.
