HELIO-HEAT-AND-COLD SUPPLY SYSTEM Russian patent published in 2017 - IPC F24F12/00 B82B3/00 F24J2/42 

FIELD: power engineering.

SUBSTANCE: invention relates to heat engineering and is intended to maintain comfortable air parameters in low-rise buildings, mainly at livestock farms. System of helio-heat-and-cold supply containing a Southern, made from an absorbing solar radiation material, and a Northern air ducts, herewith the Southern air duct is equipped with a convergent nozzle, which is installed outside the room and is made with a swirler consisting of four plates, and the outer surface of each of the four plates of the swirler is coated with a glass-like film in the form of a nanomaterial from tantalum oxide.

EFFECT: this enables to eliminate sticking of drop moisture onto the outer surface of the swirler plates, which leads to oxidation and further destruction of the material.
