The invented system, which is destined for exhaust heat recovery and air renewal in indoor spaces, operates thanks to the combination of a wind-stimulated ventilator with a chimney made of two-walled stainless plate, and presents the following features: 1) two walls the rims of which are connected in order to impede air from circulating in this area; b) an aperture opened inside the tube of the chimney (60 cm below the upper end of the chimney). The diameter of said aperture varies in respect to the diameter of the chimney’s tube; fitting of an upwardly -inclined cylindrical tube 40-50 cm long (45 deg. Inclination thereabouts). At the upper end of said tube, a second vertically-positioned cylindrical tube is adapted to contain a wind-stimulated ventilator propelling the exterior cool air between the walls of the chimney; 3) an aperture opened inside the external wall (20 -30 cm over the lower end of the chimney) for enabling the insertion of an opened cylindrical tube 10 cm long thereabouts, assisting the exit of the hot air in the indoor space. The recovery capability of the fuel’s heat-generating force amounts to 20% what is a very high performance. |
