[0023] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0024] Please refer to Figures 1-5 The diagram shown is a schematic representation of the overall structure of the heat collection and storage wall.

[0025] This embodiment provides a heat collection and storage wall, including a wall body 1 and a glass cover plate 2. The wall body 1 is provided with a heat absorption layer 3 on the outdoor side. An indoor air supply vent 11 is opened at the top of the wall body 1, and an indoor air return vent 12 is opened at the bottom of the wall body 1. The indoor air supply vent 11 and the indoor air return vent 12 can be opened and closed independently.

[0026] The glass cover plate 2 is located on the indoor side of the wall 1 and has a gap between it and the side wall of the wall 1, forming an air gap 4; an outdoor exhaust vent 21 is opened at the top of the glass cover plate 2 and an outdoor air supply vent 22 is opened at the bottom of the glass cover plate 2, wherein the outdoor exhaust vent 21 and the outdoor air supply vent 22 can be opened and closed independently.

[0027] The following will further describe a heat collection and storage wall according to this exemplary embodiment.

[0028] In some implementations, refer to Figure 1The aforementioned wall 1 is a thick solid wall, with a thickness of 30cm-50cm, and faces south. A heat-absorbing layer 3 is provided on the outdoor side of wall 1, which improves the efficiency of solar energy absorption. An indoor air supply vent 11 is located at the top of wall 1, and an indoor air return vent 12 is located at the bottom. Both the indoor air supply vent 11 and the indoor air return vent 12 can be opened and closed independently to allow for natural convection circulation of hot air, exchanging heat into the room. The two vents can also be opened and closed independently to adjust the circulation direction according to seasonal changes. For example, in summer, both vents can be closed to prevent hot air from entering the room; in winter, both vents can be opened to allow for convection circulation of hot air; during transitional seasons, the indoor air supply vent 11 at the top can be closed, and the indoor air return vent 12 at the bottom can be opened to allow indoor air to be naturally exhausted.

[0029] The aforementioned glass cover 2 is located on the interior side of the wall 1, with a gap between it and the side wall of the wall 1, forming an air gap 4. This allows the glass cover 2 to absorb solar radiation heat and heat the air within the air gap 4. The heated air is then circulated into the room through the indoor air supply vent 11 and indoor return air vent 12, improving heat collection and storage efficiency. An outdoor exhaust vent 21 is located at the top of the glass cover 2, and an outdoor air supply vent 22 is located at the bottom. Both the outdoor exhaust vent 21 and the outdoor air supply vent 22 can be opened and closed independently. The outdoor exhaust vent 21 and outdoor air supply vent 22 on the glass cover 2, which can be opened and closed as needed, allow indoor air to be exhausted or outdoor air to circulate within the air gap 4. In summer, this allows heat to dissipate from the air gap 4, reducing heat conduction into the room and thus ensuring a comfortable indoor temperature and preventing overheating.

[0030] Through the above structural design, part of the heat is transferred to the inner surface of the wall 1 through the heat conduction of the glass cover 2, the air gap 4 and the wall 1, and then heats the room in the form of radiation and convection; another part of the heat heats the air in the air gap 4 between the glass cover 2 and the wall 1. The hot air is supplied to the room through the indoor air supply vent 11 in the upper part of the wall 1, and the cold air in the room enters the air gap 4 outside the wall through the indoor return air vent 12 in the lower part of the wall 1, and is then heated by the sun and enters the room. This cycle is repeated to supply heat to the room.

[0031] like Figures 1-3As shown, in one specific embodiment, during summer, the outdoor exhaust vent 21 and outdoor supply vent 22 of the glass cover 2 are opened, while the indoor supply vent 11 and indoor return vent 12 of the wall 1 are closed. Outdoor air enters the air gap 4 through the outdoor supply vent 22, flows within it, and is then exhausted through the outdoor exhaust vent 21, carrying away heat. During the transitional season, the outdoor supply vent 22 and indoor supply vent 11 are closed, while the outdoor exhaust vent 21 and indoor return vent 12 are opened. Indoor air flows into the air gap 4 through the indoor return vent 12, flows within it, and is then exhausted through the outdoor exhaust vent 21, achieving indoor air purification. During winter, the outdoor exhaust vent 21 and outdoor supply vent 22 are closed, while the indoor supply vent 11 and indoor return vent 12 are opened. Cold indoor air is then sent into the air gap 4 through the indoor return vent 12 for heating before being sent into the room through the indoor supply vent 11, achieving indoor heating.

[0032] As a preferred implementation, each of the aforementioned indoor air supply outlet 11, indoor return air outlet 12, outdoor exhaust outlet 21, and outdoor air supply outlet 22 is equipped with an on / off valve. The on / off valves facilitate individual opening and closing of the four outlets, allowing operation as needed. They can also be configured as electrically operated valves, enabling connection to smart home systems for intelligent control.

[0033] As a preferred embodiment, the heat-absorbing layer 3 is a black coating applied to the outside of the wall 1. By utilizing the principle of black heat absorption, the heat absorption efficiency of the wall 1 can be improved, thereby transferring heat to the room.

[0034] As a preferred implementation method, refer to Figure 4 When the aforementioned wall 1 has a light-transmitting window 13, a movable sunshade venetian blind 5 is installed between the wall 1 and the glass cover plate 2, with the movable sunshade venetian blind 5 facing the light-transmitting window 13. That is, when the wall 1 has a light-transmitting area, by installing the movable sunshade venetian blind 5 on its outer side, the movable sunshade venetian blind 5 can be pulled down when necessary to prevent indoor heat loss, or opened for ventilation and cooling.

[0035] Furthermore, the top of the aforementioned movable sunshade blind 5 is installed on the outer top of the wall 1 via an electric drive device. The electric drive device controls the raising and lowering of the movable sunshade blind 5, enabling it to be connected to the home network for intelligent control and improved convenience.

[0036] As a preferred embodiment, the glass cover 2 is provided with a ventilation window so that the ventilation window and the light window 13 of the wall 1 can be opened for ventilation and cooling when necessary in summer.

[0037] like Figure 4 and Figure 5As shown, in one specific embodiment, during winter, cold indoor air enters the air gap 4 through the indoor return air vent 12, is heated and rises, and then enters the room through the indoor air supply vent 11, thus forming a convection circulation and continuously raising the indoor temperature. At night, the indoor return air vent 12 and the indoor air supply vent 11 are closed, and the movable sunshade louvers 5 are lowered to prevent heat loss. During summer, during the day, the indoor air supply vent 11 and indoor return air vent 12 of the wall 1, as well as the light window 13 and ventilation window, are closed, while the outdoor exhaust vent 21 and outdoor air supply vent 22 of the glass cover 2 are opened, allowing outdoor air to form a convection circulation outside the wall 1, carrying away the heat generated in the air gap 4. At night, the movable sunshade louvers 5 are opened, and the light window 13 of the wall 1 and the ventilation window on the glass cover 2 are opened for ventilation and cooling.
