A heat collecting wall with cultural display function suitable for solar energy-enriched areas

technical field

The invention belongs to the field of energy-saving technology and cultural display technology of building outer protective structure, and particularly relates to a heat collecting wall with cultural display function suitable for solar energy-enriched areas.

Background technique

The heat collection wall uses sunlight to illuminate the dark heat storage wall with a glass cover outside to form a greenhouse effect, heat the interlayer air between the transparent glass cover and the outer surface of the thick wall, and make the air flow into the room through the action of hot pressure. At the same time, the wall itself releases heat to the room through heat conduction and stores part of the energy. At night, the wall releases the stored heat energy into the room; on the other hand, when the indoor temperature is too high, the heat collection wall releases the heat by opening part of the glass, etc. Transfer to the outdoors by conduction, convection and radiation to prevent indoor overheating. The solar collector wall type solar room is suitable for areas in northern my country where solar energy resources are abundant and the temperature difference between day and night is relatively large, such as northern Ningxia, northern Gansu, southern Xinjiang, western Qinghai, western Tibet, etc. It will greatly improve the living environment of residents in the area. Reduce heating energy consumption in these areas.

Based on the above advantages, heat collection walls are generally installed in the solar energy-enriched areas in northern my country, but the existing heat collection walls have the following shortcomings:

1. The existing heat-collecting wall only has the function of heat storage, and is only a heat-collecting component with a single function, which is out of touch with the internal function and shape of the building, and has obvious additional characteristics.

2. The existing heat collecting wall has a single heat storage body and limited energy storage. In the current heat collecting wall, only the wall is a heat storage body, and the heat storage capacity is limited by the heat storage physical properties of the wall itself.

3. The existing heat collecting wall lacks shading components. In summer, when the solar radiation is strong and the temperature is high, when the indoor temperature reaches the critical value of comfort, the heat collecting wall continues to receive radiation, which will cause excess heat to enter the heat collecting wall, which indirectly affects the indoor thermal comfort.

4. The existing heat collecting wall transfers the heat in the wall to the room through passive heat conversion methods such as hot air convection, hot pressure ventilation and heat exchange, and the heat transfer efficiency is low.

In addition, with the implementation of the rural revitalization strategy, it is necessary to continuously promote the construction of rural civilization, so cultural publicity facilities are popularized in rural construction. However, the current rural cultural propaganda facilities are in the form of embossed cultural walls, propaganda columns, or temporary installation of multimedia curtain brackets in the square, and temporary installation of projection screens in the village square at night. These presentations have the following problems:

1. The display form is traditional, unattractive, and the publicity effect is average;

2. The indoor and outdoor display elements are scattered, requiring multiple constructions, the construction cost is high, and the later maintenance and management are difficult;

3. Once again, facilities such as embossed cultural walls are exposed outdoors and are easily damaged by man-made and weather.

Therefore, rural cultural display facilities need to be novel, intensive, easy to maintain, and improve weather resistance. It is necessary to propose a plan that can integrate cultural display facilities and integrate cultural display functions.

In view of this, the inventors have designed a heat collecting wall with a cultural display function suitable for solar energy enrichment areas, so as to solve the shortcomings of the existing heat collecting wall itself, and at the same time solve the problem of providing a carrier for the rural cultural display function.

Each curtain wall fan 14 and ventilation motor 43 are respectively connected with the solar photovoltaic The top plate 3 is connected in parallel, so as to control each fan according to the actual situation.

After the above settings, the indoor ventilation state and indoor temperature can be changed due to the following working principles, as follows:

Winter and daytime: As shown in Figure 4, open the upper and lower openable ventilation holes on the rear heat storage wall 4, and close the upper and lower openable windows on the south-facing glass curtain wall 1. The solar radiation irradiates on the thermal storage culture display body 2 and the rear thermal storage wall 4 through the south-facing glass curtain wall 1. The hot air flows upwards, and the hot air enters the room along the upper openable and closable ventilation holes 41 on the rear heat storage wall 4, and the indoor cold air enters the heat collection wall cavity from the lower openable and closable ventilation holes 42, and circulates in sequence, thereby gradually heating temperature inside the building.

Winter night: As shown in Figure 5, continue to open the upper and lower openable ventilation holes on the rear heat storage wall 4, and close the upper and lower openable windows on the south-facing glass curtain wall 1. Since the thermal storage culture display body 2 and the rear thermal storage wall 4 absorb and store thermal energy during the day, the temperature at night is higher than the surrounding environment, and the surrounding air will be heated by thermal radiation, and the hot air will rise, and it can also follow the rear thermal storage wall. The upper part of the body 4 can open and close the ventilation holes 41 to enter the room, thereby gradually heating the internal temperature of the building.

Summer and daytime: As shown in Figure 6, close the upper and lower openable ventilation holes on the rear heat storage wall 4, and open the upper and lower openable windows on the south-facing glass curtain wall 1. During the day, the solar radiation intensity is high, heating the thermal storage culture display body 2 and the rear thermal storage wall 4, and the two transfer heat to the surrounding air, so that the hot air flows upwards. The upper part of the south-facing glass curtain wall 1 can be opened by opening the window 11, and the hot air will be quickly removed from the cavity of the heat collection wall, and will not bring heat into the room; when the solar radiation is too strong, the solar radiation will illuminate the solar photovoltaic It can be converted into electrical energy, and the electrical energy will provide power for the control motor 521 of the multimedia screen 52, and the multimedia screen 52 with the sunshade function is lowered, as shown in FIG. The light from the body 4 can be reduced, thereby reducing the heat entering the interior of the building; thirdly, the solar photovoltaic roof panel 3 can also supply the converted electric energy to the curtain wall fan 14 of the south-facing glass curtain wall 1 to accelerate the outflow of hot air, which is beneficial to reduce the internal cavity temperature.

Summer night: As shown in Figure 8, open the upper and lower openable ventilation holes on the rear heat storage wall 4, and open the upper and lower openable windows on the south-facing glass curtain wall 1. Because the cultural display heat storage body 2 and the rear heat storage wall body 4 are exposed to solar radiation during the day, the temperature is high, and they begin to release heat to the outside at night, which will heat the air inside the wall and generate upward airflow. At this time, open the The upper and lower parts of the rear heat storage wall 4 can open and close the ventilation holes 41 and 42. The cold air enters the room from the lower openable and closed ventilation holes 42, and the hot air flows out from the upper openable and closed ventilation holes 41, which drives the air flow in the building. , and further open the upper and lower openable windows on the south-facing glass curtain wall 1 to increase the convection of external fresh air, thereby improving the indoor ventilation effect.

(5) Calculate the delay phase Φ _in of the indoor air temperature compared to the outdoor air temperature:

(6) Ratio of indoor air amplitude to outdoor air temperature amplitude

In the calculation formula:

According to the calculation, the temperature delay time is 1.97h, and the temperature decay factor is 7.71 times, indicating that the heat storage capacity of the room can be significantly improved.
