AIR CURTAIN

摘要

PURPOSE: An air curtain is provided to ensure excellent air conditioning effect by uniformly spraying compressed air and forming strong air layers. CONSTITUTION: An air curtain comprises a compressed-air intake body(10) and a plurality of spray nozzles(20). The spray nozzle is connected to the compressed-air intake body and sprays the compressed air downward. The spray nozzle comprises an air charged space which is transversely extended. The spray nozzle sprays the compressed air through a plurality of spray holes formed on the floor of the air charged space. The spray nozzles are located parallelly to an air layer. For the spray nozzle, the air intake hole into which the compressed air from the compressed-air intake body flows is corresponded to a part of the transverse cross-sectional area of the air charged space and a distributing plate having a downward-curved shape is installed on a decreasing part located on the lower part of the air intake hole. A fixed size of gap is formed between the front wall or the rear wall forming the air charged space and the distributing plate.
