EQUIPMENT HEAT UTILIZATION PLANT Russian patent published in 2017 - IPC F24F3/147 

FIELD: ventilation.

SUBSTANCE: invention relates to air ventilation and conditioning with regenerative heat recovery units. This is achieved by fact, that in equipment heat recovery unit, having housing, tray, freezing protection system, two-stage contact heat exchanger with atomizing irrigation system and compact thin-film corrugated nozzle, cooling system with heat exchanger, nozzle is made of compact thin-film corrugated film, 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 +30°, another, glued on it, -30°, and along length channels are made with U-shaped corrugation, wherein atomizing irrigation system nozzle consists of hollow housing with nozzle and central core, housing is made with fluid supply channel and contains coaxial, rigidly coupled with housing bushing with nozzle secured at its lower part, made in form of cylindrical two-stage bushing, which upper cylindrical stage is connected with central cylindrical core by means of threaded connection, having internal central through hole, and installed with annular gap relative to cylindrical bushing inner surface, and annular gap is connected, at least, with three radial channels, made in two-stage bushing, connecting it with annular cavity, formed by bushing inner surface and upper cylindrical stage outer surface, wherein annular cavity is connected with housing fluid supply channel, and in central cylindrical core lower part hollow cone swirler is attached, which cone shell is fixed by means of, at least, three spokes, by one end fixed on swirler conical shell, in its upper part, and by other end is in annular groove, made on central cylindrical core inner surface, wherein hollow cone swirler outer surface helical thread is made.

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