[0043] As shown in Figure 1 , Figure 2 and Figure 4 , the present application provides a heating system.

[0044] The heating system 1 is used to uniformly heat a room 2, comprising a photovoltaic Trombe (PV-Trombe) wall structure 11 for generating heat energy and a vertical wall air supply structure 12 for flowing air.

[0045] The photovoltaic Trombe wall structure 11 is arranged on the outer side of a room south vertical wall 21 and forms an air flow channel 3 with the room south vertical wall 21, and the upper side and the lower side of the room south vertical wall 21 are respectively provided with an upper air inlet 211 and a lower air inlet 212 which are communicated with the air flow channel 3.

[0046] The vertical wall air supply structure 12 is arranged on the inner side of a room north vertical wall 22 and comprises a return air inlet 121 and an air supply inlet 122 which are communicated with each other, the return air inlet 121 is horizontally arranged and faces south, and the air supply inlet 122 is vertically arranged downward, the photovoltaic Trombe wall structure 11 heats the air, the air moves upward along the air flow channel 3 and enters the room through the upper air inlet 211, and then flows through the return air inlet 121, the air supply inlet 122 and the lower air inlet 212 in turn, and reenters the air flow channel 3 to form air circulation.

[0047] It should be noted that the reason for arranging the photovoltaic Trombe wall structure 11 on the outer side of the room south vertical wall 21 is that the room south vertical wall 11 can receive more light because it faces south, the longer the light exposure time, the more electric energy and heat energy converted by the photovoltaic Trombe wall structure 11.

[0048] In a specific embodiment, as shown in Figure 2 and Figure 4As shown in the figure, the upper side of the room south vertical wall 21 is the side close to the ceiling, and the lower side of the room south vertical wall 21 is the side close to the ground of the room; the inner side of the room north vertical wall 22 is in contact with the air inside the room; and the outer side of the room south vertical wall 21 is in contact with the outside air.

[0049] In a specific embodiment, as shown in the figure, Figure 2 and Figure 4 the room is a room with a ceiling.

[0050] In an embodiment, as shown in the figure, Figure 1 and Figure 3 the vertical wall air supply structure 12 is composed of a box, a return air inlet 121 and an air supply outlet 122. The return air inlet 121 and the air supply outlet 122 are respectively in communication with the box. Air enters the box through the return air inlet 121 and is then sent out through the air supply outlet 122.

[0051] In an embodiment, the type of the return air inlet 121 includes but is not limited to a single-layer louver air inlet, a fixed louver air inlet, etc.

[0052] In an embodiment, the air supply outlet 122 adopts a strip-slit type air supply outlet, so that the hot air sent out by the air supply outlet can overcome the thermal buoyancy force, better adhere to the wall and reach the ground of the room.

[0053] In an embodiment, the box is a static pressure box, which is used to stabilize the airflow and reduce vortex, and ensure that the air is uniformly sent out from the air supply outlet 122.

[0054] In an embodiment, a heating module is arranged inside the box for heating air; the heating module is turned on when the temperature inside the room is less than a set temperature threshold, so as to increase the temperature of the air sent out by the air supply outlet, and further increase the temperature inside the room.

[0055] In a specific embodiment, the heating module can be a heating plate or a heat pump unit, and the utility model does not limit this.

[0056] In an embodiment, the box further has an air supply fan inside, which is used to adjust the air supply speed of the air supply outlet and provide power for the airflow.

[0057] In a specific embodiment, as shown in the figure, Figures 1 to 3 the vertical wall air supply structure 12 is generally arranged on the upper side (the upper side is the position close to the ceiling) of the room north vertical wall 22; the return air inlet 121 is horizontally arranged and is arranged southward, so as to absorb the heated air flowing out of the air flow channel 3; and the air supply outlet 122 is vertically arranged downward (the direction indicated by the arrow C in the figure). Figure 4 In this way, the heated air gathered on the ceiling can overcome the thermal buoyancy force and flow forward along the ground of the room.

[0058] It should be noted that the vertical wall air supply structure 12 can also be arranged at other positions of the room north vertical wall 22, as long as it is located on the opposite side of the photovoltaic Trombe wall structure 11, and the present application does not limit this, and those skilled in the art can arrange the vertical wall air supply structure 12 according to actual needs.

[0059] In an embodiment, as shown in Figure 2 The photovoltaic Trombe wall structure 11 comprises a photovoltaic cell layer 111 for converting solar energy into electrical energy.

[0060] In an embodiment, as shown in Figure 2 And Figure 3 The photovoltaic Trombe wall structure 11 further comprises a light-transmitting layer 112; the light-transmitting layer 112 is arranged on the outer side of the photovoltaic cell layer 111, and the light-transmitting layer 112 can make as much sunlight as possible to pass through and protect the internal photovoltaic cell layer 111 and other components.

[0061] In a specific embodiment, the light-transmitting layer 112 can adopt glass. Preferably, the light-transmitting layer 112 adopts low-iron glass. It should be noted that low-iron glass, also known as ultra-white glass or high-transparency glass, has a light transmittance of more than 91.5%, which is much higher than ordinary glass and can be applied to occasions requiring high transparency.

[0062] It should be noted that the light-transmitting layer can adopt other high-transparency materials, and the present application does not limit this.

[0063] In an embodiment, as shown in Figure 2 And Figure 3 The photovoltaic Trombe wall structure 11 further comprises a heat-absorbing layer 113; the heat-absorbing layer 113 is arranged on the inner side of the photovoltaic cell layer 111, for absorbing solar radiation energy and converting the solar radiation energy into heat energy.

[0064] In a specific embodiment, as shown in Figure 2 And Figure 3 The inner side of the photovoltaic cell layer 111 is the side close to the room south vertical wall 21, and the outer side of the photovoltaic cell layer 111 is the side away from the room south vertical wall 21.

[0065] In an embodiment, as shown in Figure 3 And Figure 4 The photovoltaic cell layer 111 is composed of a plurality of photovoltaic cells 111A; the plurality of photovoltaic cells 111A are sandwiched between the light-transmitting layer 112 and the heat-absorbing layer 113 (the light-transmitting layer 112 and the heat-absorbing layer 113 sandwich the plurality of photovoltaic cells 111A).

[0066] Specifically, as shown in Figure 4As shown, the light-transmitting layer 112 includes a front side of the light-transmitting layer and a first side side and a second side side of the light-transmitting layer respectively connected to the front side of the light-transmitting layer; the first side side and the second side side of the light-transmitting layer are respectively connected to the south-facing vertical wall 21 of the room; the plurality of photovoltaic cells 111A are sandwiched between the front side of the light-transmitting layer and the heat-absorbing layer 113.

[0067] In one embodiment, the type of photovoltaic cell 111A includes, but is not limited to, monocrystalline silicon photovoltaic cells, polycrystalline silicon photovoltaic cells, thin-film photovoltaic cells, etc.

[0068] In one specific embodiment, the south-facing vertical wall of the room is made of a material with high heat capacity, such as concrete or brick, which are heat-storing materials. These materials can effectively absorb and store solar radiation energy and slowly release heat when needed, thereby regulating the room temperature.

[0069] The following will combine Figure 1 , Figure 2 as well as Figure 4 Explain the specific working process of the heating system:

[0070] The photovoltaic cell layer 111 absorbs external solar energy and converts it into electrical energy; the heat-absorbing layer 113 and the south-facing vertical wall 21 of the room absorb solar radiation energy and convert it into heat energy, thus heating the air in the airflow channel 3. The heated air becomes faster and less dense, and it moves upward along the airflow channel 3. Figure 4 (In the direction indicated by the middle arrow B), and enter the room through the upwind vent 211. Then, the air will enter the housing through the return air vent 121, and then be delivered out through the supply air vent 122. Due to the wall-adhesion effect, the air delivered out of the supply air vent 122 will flow downwards along the north-facing vertical wall 22 of the room ( Figure 4 (In the direction indicated by the middle arrow C), the air flows along the floor of the room. As the air flows along the floor, its speed gradually decreases and its temperature gradually drops. At this point, due to the "chimney effect" of airflow channel 3, the air will re-enter airflow channel 3 through downwind vent 212, thus completing one air cycle. The air re-entering airflow channel 3 will be reheated and then re-enter the room through upwind vent 211.

[0071] It should be noted that when airflow moves along a curved surface (such as a wall), the airflow tends to follow the curved surface due to friction between the airflow and the surface. This phenomenon is called the Coanda Effect. The "chimney effect" in an airflow channel refers to the phenomenon where, inside a vertical hollow structure (corresponding to the airflow channel of this invention), the temperature difference between the inside and outside creates a pressure difference, causing gas flow between the inside and outside of the vertical hollow structure.

[0072] It should be noted that, through the photovoltaic Trombe wall structure 11, the air flow channel 3 and the vertical wall air supply structure 12, the hot air gathered on the ceiling flows along the wall and the ground, so that heat can also be obtained below the room, achieving uniform heating of the room. Moreover, the hot air of the air flow channel 3 can be discharged through the upper air outlet 211, which can also play a role in cooling the photovoltaic cell layer 111, thereby improving the power generation efficiency of the photovoltaic cell layer 111. The reason for this is that when the temperature of the photovoltaic cell gradually rises, the photoelectric conversion efficiency will gradually decrease, and the cell efficiency will be affected.

[0073] In an embodiment, as shown in Figure 2 , the light-transmitting layer 112 is provided with a first outdoor air valve 112A and a second outdoor air valve 112B for controlling the on-off with the outside of the room.

[0074] Specifically, as shown in Figure 2 and Figure 4 , the first outdoor air valve 112A is arranged on the side of the first light-transmitting layer; and the second outdoor air valve 112B is arranged on the side of the second light-transmitting layer. When the first outdoor air valve 112A and the second outdoor air valve 112B are opened, the first outdoor air valve 112A and the second outdoor air valve 112B are in communication with the outside of the room, and the air (ambient air) outside the room can enter the air flow channel 3. When the first outdoor air valve 112A and the second outdoor air valve 112B are closed, neither of them is in communication with the outside of the room, and the air outside the room cannot enter the air flow channel 3.

[0075] In an embodiment, as shown in Figure 2 and Figure 4 , the upper air outlet 211 is provided with an upper air outlet valve 221A for controlling the on-off of the upper air outlet 211; and the lower air outlet 212 is provided with a lower air outlet valve 212A for controlling the on-off of the lower air outlet 212. Specifically, when the upper air outlet valve 211A and the lower air outlet valve 212A are opened at the same time, the upper air outlet 211 and the lower air outlet 212 are in communication with the inside of the room, and air circulation can be achieved; when the upper air outlet valve 211A and the lower air outlet valve 212A are closed at the same time, the upper air outlet 211 and the lower air outlet 212 are not in communication with the inside of the room, and air circulation stops.

[0076] In a specific embodiment, when in winter, in order to better heat, the first outdoor air valve and the second outdoor air valve are closed, and the upper air outlet valve and the lower air outlet valve are opened; when in summer, since the temperature in the room is high, the upper air outlet valve and the lower air outlet valve are closed, and the first outdoor air valve and the second outdoor air valve are opened.

[0077] In a specific embodiment, when the vertical wall air supply structure is at an air supply speed of 3.5 m / s and a temperature of 30.9℃, the average temperature of the room can reach the design temperature of 20.0℃. Using the heating system of the present embodiment, the average temperature of the room is increased to 20.9℃, and then when the average temperature of the room is reduced to 20℃, the air supply temperature of the vertical wall air supply structure 12 is reduced from 30.9℃ to 28.0℃, achieving the purpose of energy saving.
