AIR ADDITIONAL MOISTENING SYSTEM Russian patent published in 2018 - IPC F24F5/00 F24F6/00 

FIELD: ventilation.

SUBSTANCE: invention relates to air conditioning technology and can be used to create comfortable microclimate conditions in production facilities, in particular as local air additional moistening systems. In the air additional moistening system consisting of pneumatic nozzles, piping networks serving to supply water and compressed air to them, and a pneumatic nozzles control unit, the nozzle is made acoustic, comprising a body with an internal acoustic oscillator in the form of a nozzle and a resonator made in the form of concentric annular slits arranged in a plane perpendicular to the body axis, a ring with a conical surface connected to the body and serving to form the generated jet of the sprayed liquid, and a sprayer forming a liquid film covering the output from the oscillator and fixed to the body by a hollow rod with a screw swirling nozzle at the end and a pad for placing an annular platform, on which the liquid flows from the sprayer, and the resonator is made in the form of at least one spherical cavity located in the wall of the ring, herewith the spherical cavity is connected by a calibrated opening with the annular slit formed by the end faces of the body and the ring from the side of the conical surface, and the ring is arranged to be fixedly movable along the axis of the body by means of a threaded connection.

EFFECT: increased efficiency and reliability of the process of pneumatic spraying of water.
