INTEGRATED BASEMENT VENTILATION APPARATUS Russian patent published in 2018 - IPC F24F7/10 F04D25/08 

FIELD: electrical equipment; ventilation.

SUBSTANCE: present invention relates to an integrated basement ventilation apparatus. It comprises: an air supply fan installed in an air supply inlet of each floor of a basement structure; air exhaust fan installed in an air exhaust outlet in each floor toward an air exhaust shaft of the basement structure; plurality of connecting fans, installed on a ceiling of each floor of the basement structure; and a controller receiving electrical signals from sensors uniformly distributed in the ceiling of each floor of the basement structure for generally controlling of fans; air supply fan and the air exhaust fan include a cylindrical fan supported in a polygonal column-shaped frame, at least one of the air supply fan and the air exhaust fan is additionally provided with a fire-fighting damper which is opened or closed depending on whether the fan operates or not and which can be forcedly closed through a temperature-dependently operated fuse, at least one of the air supply fan and the air exhaust fan is additionally provided with spray nozzles which suck in water by means of negative pressure generated due to the air blowing to finely spray the water. In particular, the present invention can remarkably improve condition and maintenance of whole facilities by significantly enhancing air quality of the basement structure as well as being capable of extinguishing fire at an early stage.

EFFECT: thus, the present invention can control an increase in temperature within a basement structure at a low cost and improve fire safety by preventing fire from spreading to other floors.
