Description

Technical Field

[0001] The present invention relates to the technical field of building engineering, and more particularly to an assembled phase-change wallboard capable of automatically storing energy and releasing heat and a construction method thereof. Background Art

[0002] In the context of the rapid development of the global construction industry today, prefabricated walls, as an innovative construction technology, are gradually becoming the focus of industry attention. The factory prefabrication and on-site assembly method greatly reduces environmental pollution and resource waste at the construction site, shortens the construction cycle, and improves labor productivity. It conforms to the concept of sustainable development and embodies the characteristics of green ecology. Therefore, it has been actively promoted and applied in the construction industry.

[0003] In my country, the energy consumption of air conditioning and heating in building spaces is also an aspect that cannot be ignored. Phase change materials have the functions of heat storage and heat release. Phase change energy storage technology is widely used in walls. Applying phase change materials to interior walls and partitions can help regulate indoor temperature, absorb heat during the day and release it at night, thereby balancing indoor temperature changes and improving comfort. Combining phase change materials with traditional insulation materials on exterior walls can reduce the speed of heat transmission, improve the insulation effect of exterior walls, and reduce the energy consumption of buildings. On this basis, exploring the combination of phase change energy storage technology and prefabricated wall technology can bring new breakthroughs in the field of building energy conservation.

[0004] However, under weather conditions without sunlight, such as cloudy days, rain, snow, and haze, the performance of the phase change energy storage wall is limited, and it is difficult to fully demonstrate its advantages in energy storage and heat release, which in turn affects the realization of building energy-saving goals.

[0005] Therefore, how to provide an assembled phase change wall panel and construction method that can automatically store and release energy and fully demonstrate the energy storage and heat release performance is an urgent problem that needs to be solved by technical personnel in this field.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-12 The embodiment of the present invention discloses an assembled phase change wall panel capable of automatically storing energy and releasing heat, comprising:

[0044] Wall component 1;

[0045] The heating device 2 includes a water pipe 7, a pumping room 8 and a heating room 9. The water pipe 7 is arranged in a rotary type in the wall assembly 1. The water inlet of the water pipe 7 is connected to the pumping room 8, and the water outlet of the water pipe 7 is connected to the heating room 9. A pumping pump 12 is arranged in the pumping room 8. One end of the pumping pump 12 is connected to the water pipe 7, and the other end of the pumping pump 12 is connected to the heating room 9. A water inlet 14 is arranged on the heating room 9, and a heating device is arranged in the heating room 9. The water pipe 7 is arranged in a rotary type to ensure the uniformity of energy storage of the fixed phase change plate 5. The heating device can heat the water temperature to 100°C to ensure that sufficient energy is provided for the fixed phase change plate 5. The water pipe 7, the pumping room 8 and the heating room 9 work together to provide a heat source for the fixed phase change plate.

[0046] In this embodiment, the wall assembly 1 includes a cement mortar layer 3, a reinforced concrete layer 4, and a shaped phase change plate 5. The cement mortar layer 3 is arranged on the side of the reinforced concrete layer 4 away from the heating device 2, and the shaped phase change plate 5 is arranged on the side of the reinforced concrete layer 4 close to the heating device 2; the cement mortar layer 3 is located on the outdoor side, the reinforced concrete layer 4 is located in the middle, and the combined layer of the shaped phase change plate 5 and the insulation board 6 is located on the indoor side.

[0047] In this embodiment, the wall assembly 1 also includes an insulation board 6, which is arranged on the side of the shaped phase change plate away from the reinforced concrete layer 4, and the insulation board 6 is located around the shaped phase change plate 5; the insulation board 6 is used to ensure that the shaped phase change plate 5 transfers heat in one direction.

[0048] In this embodiment, high-legged rows of buckles 11 are set at the rotating positions of the water pipes 7, and multiple high-legged rows of buckles 11 are arranged in parallel and at intervals. The water pipes 7 are fixed in the reinforced concrete layer 4 through the high-legged rows of buckles 11; the high-legged rows of buckles 11 improve the connection between the shaped phase change plate 5 and the concrete.

[0049] In the present embodiment, a check valve 13 is also included. The check valve 13 is located in the pumping room 8. The check valve 13 is arranged on the pipeline connecting the water pipe 7 and the pumping pump 12. The check valve 13 is parallel to the ground and higher than the water level in the heating room 9. By arranging the check valve 13 to be parallel to the ground and higher than the water level in the heating room 9, it can be ensured that there is sufficient water in the water pipe 7 in the shaping phase change plate 5, and the water in the water pipe 7 can be prevented from flowing back.

[0050] In this embodiment, the heating device 2 further includes a control console 10, on which a switch button, a temperature adjustment button and a temperature display screen are provided.

[0051] On the other hand, the present invention provides a method for constructing an assembled phase change wall panel with automatic energy storage and heat release, based on the above-mentioned assembled phase change wall panel with automatic energy storage and heat release, specifically comprising the following steps:

[0052] Step 1: pouring reinforced concrete layer 4, marking the embedding position and embedding depth of high-leg row buckles 11;

[0053] Step 2: Before the reinforced concrete hardens, insert the high-legged buckle 11, paying attention to avoid the position of the steel bars, so that the marked area below is completely buried in the reinforced concrete layer 4;

[0054] Step 3: After the reinforced concrete hardens, lay the silicone hose and fix it with the high-leg buckle 11;

[0055] Step 4: Cast the finalized phase change plate 5, demould it 24 hours after casting, and naturally sprinkle water for curing;

[0056] Step 5: After the curing is completed, the insulation board 6 is pasted around the shaped phase change board 5;

[0057] Step 6: After the wall installation is completed, the pumping room 8, heating room 9 and control console 10 are installed, and cement mortar is applied to the outdoor wall.

[0058] In addition, in the present embodiment, the water pipe 7 adopts a silicone hose, the outer diameter of the water pipe 7 is 1 / 3 to 1 / 2 of the thickness of the formed phase change plate 5, the wall thickness of the water pipe 7 is between 1 and 2 mm, the distance between the water pipes 7 is between 50 and 100 mm, and the distance to the edge of the formed phase change plate 5 should be greater than 20 mm. In order to accurately fix the position of the water pipe 7, a high-foot row of clips 11 is used for fixing, and each water pipe 7 parallel to the vertical direction is arranged with at least 3 high-foot rows of clips 11 for fixing. The high-foot row of clips 11 includes an upper part and a lower part. The upper part is U-shaped and is used to fix the water pipe 7. The size is determined according to the outer diameter of the water pipe 7. The lower part is concave and convex, which increases the contact with the reinforced concrete layer 4 and effectively improves the bonding between the reinforced concrete layer 4 and the formed phase change plate 5. The lower length of the high-foot row of clips 11 should be between 50 and 100 mm.

[0059] The cement mortar layer 3 has a thickness of 20 mm and a strength of M10.

[0060] The reinforced concrete layer 4 is arranged in the middle layer to play a load-bearing role. The reinforced concrete layer 4 has a thickness of 200 mm and a strength of C35.

[0061] The heat preservation plate 6 is fixed around the shaped phase change plate 5 by using an adhesive, so that the shaped phase change plate 5 maintains unidirectional heat transfer, thereby reducing heat loss.

[0062] The shaped phase change plate 5 is made of a mixture of paraffin, high-density polyethylene and expanded graphite. The phase change temperature should be between 26 and 30°C, the phase change latent heat should be above 150J / g, and the thickness is designed to be between 30 and 80mm according to demand. The insulation board 6 uses XPS polystyrene extruded board.

[0063] The console 10 is also provided with an automatic control button, a manual water pumping control button and a manual heating control button, which can monitor the temperature of the phase change plate and water in real time, and can adjust the temperature, control the heating and water pumping processes according to actual needs, so as to meet the usage requirements in different scenarios.

[0064] How it works

[0065] When the heating equipment is turned on, the control console 10 measures the surface temperature of the fixed phase change plate 5 and the water temperature. When the surface temperature of the fixed phase change plate 5 is lower than its phase change temperature, the heating room 9 starts to operate. After heating to the set temperature, the hot water is transmitted to the water pipe 7 in the fixed phase change plate 5 through the pumping room 8. The phase change material stores energy through the temperature of the water pipe 7. When the surface temperature of the fixed phase change plate 5 is higher than its phase change temperature by 5-10°C, the heating equipment enters a sleep state. At this time, the phase change material releases energy to increase the indoor temperature.

[0066] When the surface temperature of the fixed phase change plate 5 is lower than its phase change temperature, the previous operation is continued, and this is repeated to maintain the indoor temperature.
