The operation mode of the window structure provided by the present invention is described below by taking the first air valve 6 as an example, and the operation mode generally includes the following steps:

(1) Natural energy processing circulating wind mode

Referring to fig. 1, in summer, the fan 202 is started, natural cooling water is introduced into the heat exchanger 201, that is, the cooling water of the cold and heat source 12 is used for cooling the air in the air cavity 103 of the double-layer glass 1, so as to reduce the temperature of the air cavity 103, and thus reduce the heat entering the house through the window structure; similarly, in winter, the heat exchanger 201 heats the air in the air cavity 103 of the double glazing 1 by using the hot water from the cold and heat source 12 (such as solar energy and buried pipes), so as to raise the temperature of the air cavity 103, thereby reducing the amount of heat dissipated through the window structure indoors.

Moreover, the state of the shutter 3 can be flexibly adjusted according to the illumination intensity and the indoor illumination requirement, so that a good visual field can be ensured, and the effect of reducing cold and heat loads can be achieved.

(2) Solar heating mode

Referring to fig. 3, when heat is needed in winter, the louver 3 absorbs solar radiation heat, the temperature of the air cavity 103 of the double-layer glass 1 rises, the first air valves 6 at the upper part and the lower part of the inner layer glass 102 are opened, indoor air enters the air cavity 103 from the first air valve 6 at the lower part and leaves the air cavity 103 from the first air valve 6 at the upper part to return to the indoor through the buoyancy effect, and therefore the indoor air enters the high-temperature air cavity 103, is heated and then returns to the indoor.

In addition, when the buoyancy lift force is insufficient, the fan 202 can be started to supplement the air circulation power.

(3) Outdoor air free cooling mode

Referring to fig. 4, when the outdoor air temperature is low, the first air valves 6 at the upper and lower parts of the outer glass 101 are opened, the outdoor air enters from the first air valves 6 at the lower part and is discharged from the first air valves 6 at the upper part, and the heat of the air cavity 103 is taken away by the outdoor air, so that the temperature of the air cavity 103 of the double-layer glass 1 is reduced, and the heat entering the house through the window structure is reduced.

Moreover, when the buoyancy force alone is insufficient, the fan 202 can be started to supplement the air circulation power.

(4) Fast ventilation mode

Referring to fig. 5, when rapid ventilation is performed in a room, all the first dampers 6 of the upper and lower portions of the double glass 1 may be opened.

(5) Indoor air exhaust heat dissipation mode

Referring to fig. 6, when there is exhaust air in the room, the first air valves 6 at the lower part of the inner glass 102 and the upper part of the outer glass 101 are opened, the exhaust air enters from the first air valve 6 at the lower part and is discharged from the first air valve 6 at the upper part, the heat of the air cavity 103 is taken away by the exhaust air with lower temperature, and the temperature of the air cavity 103 of the double-layer glass 1 is reduced, so that the heat entering the house through the window structure is reduced.

When the indoor air is not exhausted, the fan 202 can be started to open the first air valves 6 at the upper and lower parts, so that air can enter from the first air valve 6 at the lower part and be exhausted from the first air valve 6 at the upper part, and the heat of the air cavity 103 can be taken away by the indoor air with lower temperature.

(6) Mode of energy storage

Referring to fig. 9, in summer, when cooling is performed, a natural energy collection device such as a cooling tower can be used for cold accumulation at night, cold energy is stored in an energy storage tank for use by the heat exchanger 201 in the daytime, lower temperature at night is fully utilized, and energy efficiency of the natural energy collection device is improved; in addition, the valley electricity can also be used for producing cooling water to be stored in the energy storage tank for the heat exchanger 201 to use in the daytime. When heat is supplied in winter, hot water is produced by using natural energy collecting devices such as a solar heat collector and the like in the daytime and is stored in the energy storage tank, and the hot water in the water storage tank is introduced into the heat exchanger 201 at night to heat the air cavity 103, so that heat transfer from indoor to outdoor is reduced.

In addition, the first air valve 6 is arranged on the window structure, so that the cold and heat source 12 is not started when the conditions are appropriate, the energy consumption of the circulating pump 13 is reduced, and the power of the fan 202 is utilized to drive the air to circulate; when the buoyancy lift force is enough, the fan 202 can be closed, the energy consumption of the fan 202 is reduced, and the buoyancy lift force is utilized to drive the air to circulate; the invention can realize the multiple operation modes by arranging the first air valves 6, thereby reducing the indoor load.

It is understood that the working principle of the other air valves of the present invention is similar to that of the first air valve 6, and the detailed description is omitted here.

In conclusion, the window structure provided by the invention has the characteristics of simple structure, high reliability, convenience and quickness in use, capability of reducing indoor load in summer and winter, capability of ensuring visual field effect and the like, and can be applied to glass enclosing structures of fixed glass curtain walls and openable glass windows.
