METHOD OF LOCAL PLENUM VENTILATION COMBINED WITH AIR HEATING Russian patent published in 2010 - IPC F24F11/00 

FIELD: heating.

SUBSTANCE: air is supplied from the outside through supply filter by means of supply fan to heat-insulated supply air duct routed along the corridor and the end of which is connected to heat-insulated exhaust air duct through which the air is removed from rooms by means of exhaust fan; at connection point of these supply and exhaust air ducts there is check valve; in order to avoid pressure differential in those air ducts, air is supplied from supply air duct through supply air duct of the room to each room passing at that the supply flow-controlled valve and channel heater, which are controlled with microprocessor unit; then as per values of sensors installed in rooms the air is removed from each room through the room exhaust air duct passing at that the exhaust flow-controlled valve also controlled with microprocessor unit to the exhaust air duct and then from the building.

EFFECT: power consumption economy, optimal microclimate in all rooms separately.
