AIR HEAT AND MOISTURE TREATMENT DEVICE WITH HEAT RECOVERY Russian patent published in 2017 - IPC F24F5/00 

FIELD: ventilation.

SUBSTANCE: invention relates to heat and moisture air treatment with energy saving system and can be used, in particular, in air conditioning. This is achieved by fact, that heat and moisture air treatment device with heat recovery, consisting of air intake and air distributing devices, located in room upper zone, and air discharging devices, additionally contains air dry cleaning device, supplied from room by air intake and air discharging device, connected to humidification and wet cleaning device, and climatic plant for outside air cleaning and heating, as well as humidification and wet cleaning and climatic plant air flows mixing unit, connected with distribution device, each of unit humidification and wet cleaning nozzles contains 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 through internal central hole, and installed with annular clearance 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, 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 air heat and moisture treatment systems efficiency by heat recovery based on devices with opposite swirling flows.
