Abstract

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.

Description

The present invention relates to the field of construction and can be used to increase the energy efficiency of buildings and structures for various purposes.

Known window units, including vacuum double-glazed windows from two sheets of flat glass. The space between the glasses is evacuated (article by Tabunshchikov Yu.A. in the journal "Energy Saving" No. 2/2008 "Window as an intellectual element of the building structure" website http://www.abok.ru/for_spec/articles.php?nid=3915, analog ) The disadvantages of this technical solution are the low strength characteristics of the vacuum glass and the difficulties in maintaining its tightness during long-term operation.

Closest to the proposed invention, the technical solution is an energy-active window unit (application for the grant of a patent of the Russian Federation No.20120006, EV 3/24, 2010). The main disadvantage of this invention is that the heat pipe is not able to sufficiently effectively cool the side of the Peltier element facing the room, due to which the overall efficiency of the system is reduced.

The present invention solves the technical problems of improving the heat-shielding qualities of window blocks and increasing the energy efficiency of buildings.

The stated technical problem is solved due to the fact that the energy-active window unit, which includes at least one two-chamber double-glazed unit, consisting of an external chamber facing the building outside and the internal chamber facing the building inside, while at least one thermoelectric converter is built into the glass packet, made with the possibility of cold the time of year for cooling the outer glass pane, and in the warm season, with the possibility of heating the outer pane of the double-glazed window, differs in that one hundred ONET thermoelectric conversion element installed radiator and a fan for applying heated air to the room in winter and cool air in the summer. In this case, the intake of air supplied to the radiator can be carried out from the inner chamber of the double-glazed window, while the air supply through the radiator is organized back into the inner chamber of the double-glazed window. In addition, heat pipes can be used on the thermoelectric converter side facing the street to remove heat in the summer and heat in the winter, while it is possible to use heat pipes with a finned surface. Heat pipes can be made in the shape and size of the distance frame or part thereof and installed instead of it or this part. Also, the energy-active window unit is additionally equipped with a system for electrically heating the mounting seam and adjoining units of the window unit to the wall opening, as well as photoelectric converters of solar energy into electrical energy and electric energy accumulators, which provide power to the thermoelectric converter and electric heating systems for the installation seam and adjoining units in day and night time.

The proposed device allows you to solve the technical problem, because heat loss is reduced by reducing the temperature difference between the outer camera of the glass and the environment, while part of the heat or cold (depending on the time of year) is returned to the room.

The essence of the proposed technical solution is illustrated by the circuit shown in figure 1.

An energy-active window unit includes at least one two-chamber double-glazed window 1, consisting of an external chamber 2 facing the building outside and an internal chamber 3 facing the building, and at least one Peltier thermoelectric element 4 is integrated in the glass packet. At the same time, in order to increase the heat exchange efficiency, a heat pipe 5 is installed between the Peltier element and the outer glass pane of the glass unit, connected to the module by a plate 6 made of a material with a high coefficient of thermal conductivity (for example, copper). In addition, it is possible to install heat pipes instead of the distance frame 7 or part thereof. On the side of the Peltier element facing the room, a radiator 8 is installed with a fan 9 attached to it.

The principle of operation of the invention is as follows.

In the cold season, part of the thermal energy passing through the double-glazed window 1 out of the building is returned by the Peltier thermoelectric element 4 to the inner chamber 3 of the double-glazed window 1, while the heat pipe 5 provides heat from the outer chamber 2 and this heat is supplied to the element 4, and the radiator 8 cools the hot side of the Peltier element. In this case, the fan 9 creates an air flow through the radiator 8, as a result of which the temperature in the inner chamber 3 of the double-glazed window 1 rises, and the temperature in the outer chamber 2 decreases and approaches the temperature of the outside air. As a result, the heat loss of the window unit to the environment is reduced. In this case, the air heated on the radiator 8 is fed back into the room, due to which the temperature of the air in the room rises.

In the hot season, if there is excess heat in the building’s premises, the Peltier thermoelectric module 4 reverses, heats the external chamber 2 to a temperature that increases the temperature of the outside air, while the heat pipe 5 provides heat removal from module 4, as well as heat distribution in the external chamber 2, fan 9 creates an air flow through the radiator 8. At the same time, the temperature in the outer chamber 2 rises and approaches the temperature of the outside air, and heat input into the room through the window unit is reduced. In this case, the air cooled on the radiator 8 is fed back into the room, due to which the air temperature in the room decreases.

Unlike the prototype, the proposed technical solution allows for effective cooling of the side of the Peltier element facing the room, thereby increasing the efficiency of the system as a whole, which, in turn, improves the heat-shielding qualities of window blocks, as well as the energy efficiency of buildings in general.
