VENTILATION SYSTEM WITH HEAT RECOVERY UNIT Russian patent published in 2018 - IPC F24F12/00 F24F5/00 

FIELD: ventilation.

SUBSTANCE: invention relates to air conditioning and ventilation technology and can be used to create comfortable microclimate conditions in domestic, administrative and industrial premises. In a ventilation system with a heat recovery unit comprising a fan, a first and a second heat exchangers and units, where adiabatic cooling and moistening of the supply air with water are performed, the water is recirculated by a pump, and the units are made as heat-mass exchange devices with a vibrating fluid bed, in a tray with a nozzle where vibrators are located, the nozzle of the heat exchanger irrigation system comprises a body, a fitting and a swirling insert coaxially arranged therewith, in the connection there is an expanding channel for supplying liquid to the cylindrical opening, which is axially symmetric to the body and smoothly passes into a coaxial with it shaped hole, made in the form of a diffuser, cylindrical hole of the body accommodates cylindrical swirl insert, arranged axially symmetric with the body and having outer peripheral screw-like threaded channels, wherein along the axis of the vortex insertion, a central axial aperture with a screw thread on the inner surface opposite to the channel cutting direction is formed, wherein the vortex insert is installed in the housing through the elastic gaskets and is pressed by the fitting by means of a threaded connection of the body-fitting, wherein the external screw-like threaded channels and screw threading on the inner surface of the axial opening of the vortex insertion are made with a variable pitch, the swirl insert is made of wear-resistant material, wherein at the top of the nozzle, a perforated disk is mounted in which a hollow helical conical swirler is mounted in an expanding channel for supplying liquid to the cylindrical hole made axially symmetrically to the nozzle body, and on the surface of the hollow screw conical swirler a screw through cutting is made.

EFFECT: increased efficiency and reliability of heat and moisture treatment of the air.
