METHOD AND DEVICE FOR RECUPERATING HEAT OF AIR Russian patent published in 2006 - IPC F24F12/00 F24F3/147 F24F5/00 

FIELD: air ventilation and conditioning.

SUBSTANCE: method comprises settings fans in the passages for inflowing and outflowing air and mounting the chamber with the heat regenerative recuperator perpendicular to the passages. The chamber is made of housing whose walls are provided with heat insulating panels and is connected with the passages for inflowing and outflowing air. The regenerative recuperator is made of an extensible frame separated by a baffle into two spaces. The baffle is provided with bearings for the core of the drum that is made of belts made of corrugated aluminum foil tightly wound on the core. The periphery part of the drum made of a ring is rigidly connected with the core and is provided with at least two screw blades. The passages for inflowing and outflowing air receive filters for cleaning air. The recuperator comprises housing, passages for inflowing and outflowing air with fans, and chamber provided with regenerative heat recuperator arranged perpendicular to the passages. The housing is made of a parallelepiped whose walls are made of heat-insulating panels.

EFFECT: enhanced efficiency.
