VENTILATION SYSTEM WITH WASTE HEAT EXCHANGER Russian patent published in 2017 - IPC F24F5/00 B05B1/00 

FIELD: ventilation.

SUBSTANCE: invention relates to equipment of air conditioning and ventilation and can be used to make comfortable microclimate conditions in habitable, administrative and production premises. This is achieved by fact, that in ventilation system with waste heat exchanger, containing fan, first and second warming up heat exchanger and devices, where plenum air adiabatic cooling and moistening with water takes place, water recirculating is performed by pump, and devices are made as heat-mass exchange devices with vibrating fluid bed, in which tray with nozzle vibrators are arranged, heat exchanger irrigation system nozzle comprises housing with screw coaxially arranged in housing lower part, and liquid supply union with cylindrical hole arranged in housing upper part, connected with diffuser, axially symmetric to housing and union, screw is pressed into housing with formation of cylindrical chamber, located above screw, coaxially to diffuser, and in-series connected with it, wherein screw is made solid, and screw outer surface represents two in-series connected surfaces, one of which is, at least, single-thread helical groove with right or left hand thread, and located inside housing, and second surface is made smooth in form of body of revolution, axisymmetrically connected with spraying disc, located perpendicular to housing axis, and extends beyond housing lower part end surface, wherein as generatrix, of said surface, can both be straight line, and n-order curve, and spraying disc surface extending beyond housing lower part end surface, is made bent towards housing lower part and has radial cutouts on periphery, alternating with spraying disc surface solid part.

EFFECT: technical result is increase in heat and moisture air treatment efficiency and reliability.
