METHOD OF HEAT UTILISATION OF HEATED AIR AND HEAT EXCHANGER Russian patent published in 2017 - IPC F24F5/00 

FIELD: ventilation.

SUBSTANCE: heat exchanger of heated air comprises a housing, channels for the supply and exhaust air with fans, chamber with a regenerative heat exchanger, placed perpendicularly to the channels, the housing is made in form of parallelepiped, whose walls are made of insulated panels interconnected by quick-locks, and a regenerative heat exchanger is a retractable frame, divided into two spaces by a partition, where drum core supports are fixed, the drum is formed of corrugated aluminium foil ribbons, tightly wound on the core, and at the peripheral portion of the drum, formed in the shape of a ring that is rigidly connected to the core by three radial spokes, at least two helical blades are fixed in order to rotate the air flow, wherein the partition frame, with the drum mounted on it, forms the channels connected to the channels for supply and exhaust air, in each of which air cleaning filters are located. The disperse material with unclosed pores and with a high coefficient of heat build-up is made in the form of a cylindrical ring, on the side, inner and outer surfaces of which a helical thread is made, or in the form of a ball on the surface of which blind holes of hemispherical shape are made, or a cylindrical ring, on the side and the inner surface of which partitions in the form of perpendicular to the ring axis washers with holes are fixed, whose axes are asymmetrical to the axis of ring, or in the form of a fitting into a circle block, consisted of seven interconnected side faces of hexagonal parallelepipeds without upper and lower bases.

EFFECT: increased efficiency of the heat exchange of exhaust air, saving energy resources, simplifying the design, installation and maintenance.
