THERMAL VENTILATION Russian patent published in 2008 - IPC F24F12/00 F24F7/08 F24F11/08 

FIELD: heating.

SUBSTANCE: heating ventilation is designed to create air exchanging process inside living quarters and industrial rooms ensuring plenum air heating. Thermal ventilation consists of vertical duct and floor layout. Besides, vertical duct must be two-wall. Air flow cutoff devices are installed in places of floor layout connection, inside walls. Bottom cross section of duct is overlapped by flange, where fan heater is mounted vertically by means of brackets. Fan heater consists of tube and ceramic insert with three glowing filaments, ignition electrode and five remote contacts. Photo sensor and three thermal sensors are installed on upper edge of fan heater. Diaphragm pressure gauge with three pairs of electrical contacts is installed in the upper part of duct. Fuel pipeline with orifice plug is put into fan heater through flange. Electromagnetic valve controls the amount of supplied fuel. Two-wall heat-exchanging chamber is adjacent to outlet cross section of duct. It is filled up with tubes and insulated from outside and provided with discharge channel. Plenum air is supplied to heat-exchanging chamber through air filter.

EFFECT: creation of simple, easy to use, cheap and effective arrangement of thermal ventilation.
