VENTILATION SYSTEM WITH HEAT RECOVERY UNIT Russian patent published in 2018 - IPC 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. This is achieved by the fact that in a ventilation system with a heat recovery unit containing a fan, a heat exchanger of the first and second preheaters and apparatuses, where there is adiabatic cooling and moistening of supply air with water, the water is recirculated by a pump through the injector irrigation system, and the apparatuses are made by heat and mass exchange devices with a vibrating bed, in a pallet with a head of which vibrators are located, the injector of the heat exchanger irrigation system comprises a body, union and a coaxially arranged swirling insert with an external helical thread and an expanding conical hole inside, wherein in the union there is a cylindrical opening, connected to the diffuser, which is axially symmetric in the body, and in the lower part of the body, there is a nozzle, axisymmetric to the body, which is made with a two-stage diffuser, coaxial to the swirling insert , the first stage of the diffuser is a continuation of the expanding conical hole made inside the swirling insert, which is made from wear-resistant material, and the second stage of the diffuser is an extension of its first stage, while on its inner conical surface there is a helical thread, herewith the conical surface with the helical thread of the second stage of the diffuser is made perforated, and in the lower part of the body, coaxially to it, a cylindrical shell is fixed, on which a flow divider is installed, which is made, at least, in the form of two rods connected to each other in the lower part, obliquely to the nozzle axis, to which a vertically disposed rod is attached, onto which there is a swirler made in the form of a cone with helical blades enclosing the rod with a clearance and resting in the lower part on a thrust located horizontally and perpendicular to the rod.

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