ENERGY ACTIVE WINDOW UNIT Russian patent published in 2012 - IPC E06B3/00 

FIELD: construction.

SUBSTANCE: in the cold season of the year a part of thermal energy passing through an insulated glazing unit 1 outside a building is returned with a thermoelectric Peltier element 4, into an inner chamber 3 of the insulated glazing unit 1. A heat tube 5 provides for heat intake from an outer chamber 2 and supply of this heat to the element 4, and a radiator 8 cools down the hot side of the Peltier element. The fan 9 creates an air flow through the radiator 8, as a result of which temperature in the inner chamber 3 of the insulated glazing unit 1 increases, and temperature in the outer chamber 2 reduces and approaches the ambient air temperature. Therefore window unit heat losses to environment are reduced. At the same time air heated on the radiator 8 is sent back into a room, as a result air temperature in a room increases. In the hot season of the year with availability of surplus heat in rooms the thermoelectric Peltier module 4 reverses, heats the outer chamber 2 to the temperature that increases the ambient air temperature, at the same time the heat tube 5 provides for heat release from the module 4, and also heat distribution in the outer chamber 2, the fan 9 creates an air flow via the radiator 8. At the same time the temperature in the outer chamber 2 increases and approaches the ambient air temperature, and heat supplies into a room via the window unit are stopped. At the same time air cooled on the radiator 8 is sent back into a room, as a result of air temperature in a room reduces.

EFFECT: improved heat saving.
