EQUIPMENT HEAT UTILIZATION PLANT Russian patent published in 2017 - IPC F24F12/00 

FIELD: ventilation.

SUBSTANCE: invention relates to air ventilation and conditioning with regenerative heat recovery units. This is achieved by fact, that in equipment heat utilization unit, comprising housing, tray, freezing protection system, two-stage contact heat exchanger with nozzle, cooling system with heat exchanger, nozzle is made of compact thin-film corrugated film with thickness of 0.4…0.8 mm, wherein nozzle molded sheets are glued, and nozzle surface represents triangular-shaped alternating channels, which are inclined to coolant draining axis in counter-flow scheme: one sheet at angle of +30°, other, glued onto it, -30°, and along length channels are made with U-shaped corrugation, 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 LH or RH 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 said surface generatrix 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 sprayer disc surface solid part.

EFFECT: technical result is increase in process equipment water heat utilizing efficiency.
