VENTILATION SYSTEM WITH HEAT RECOVERY UNIT Russian patent published in 2017 - IPC F24F5/00 

FIELD: ventilation.

SUBSTANCE: in ventilation system with a heat recovery unit containing a fan, a heat exchanger for the first and second preheaters, and apparatuses where adiabatic cooling and moistening of supply air with water takes place, water is recirculated by a pump, and the apparatuses are made by heat and mass transfer apparatus with a vibrofluidized bed, in a tray with nozzles of which vibrators head, the nozzle is made in the form of a cylindrical ring, on the side, inner and outer surfaces of which a screw thread is made, or in the form of a ball, on the surface of which blind holes of a hemispherical shape are made, or in the form of a cylindrical ring, on the lateral inner surface of which are fixed partitions in the form of holes perpendicular to the axis of the ring whose holes are asymmetric to the axis of the ring, or in the form of a block, consisted of seen side edges of hexagonal parallelepipeds without upper and lower bases.

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