Description

Technical Field

[0001] The present invention relates to the technical field of building heating and ventilation, and in particular to an assembled floor radiation heating system and a construction method thereof. Background Art

[0002] In the current field of floor heating and building ventilation, traditional floor construction methods have some obvious limitations, and these methods cannot fully meet the national requirements for green buildings and energy conservation and environmental protection. Specifically, there are two main traditional floor construction methods: one is the wet method, which will increase the thickness of the floor, seriously increase the building load, and cause a large heat loss. In addition, its construction period is long and later maintenance is also very inconvenient; the other is the prefabricated groove insulation module method, which can reduce a certain amount of heat loss, but the cost is high, the construction precision requirements are high, and the texture is poor when stepped on.

[0003] With the implementation of the "Assembly Building Evaluation Standard" (GB / T 51129-2017), prefabricated buildings have begun to receive more attention. Under this standard, the main structure and enclosure wall structure have been significantly developed, but the progress in the practice of fully decorated dry floor is relatively slow. Traditional wet construction methods cannot meet the requirements of the new standard, and although dry prefabricated groove insulation modules can meet the standards, they are often limited in application due to cost and construction requirements.

[0004] In terms of building ventilation, the existing floor structures are mostly closed structures, lacking effective space to promote air circulation, which limits the effect of floor heat exchange. If air circulation can be achieved in the indoor environment, it will help increase convective heat exchange, especially in winter, which can more effectively increase the temperature of the indoor environment and reduce energy consumption.

[0005] Therefore, the construction industry urgently needs a new type of floor radiant heating system and its construction method. This system should not only be able to promote air circulation and meet national standards, but also have the characteristics of low cost and efficient heat exchange. Summary of the invention

[0006] The purpose of the present invention is to provide an assembled floor radiant heating system and a construction method thereof, so as to solve the problems of large heat loss in traditional floor construction methods, high cost of prefabricated groove insulation modules, high construction requirements, and inability to generate air circulation in a closed structure on all sides.

[0007] To achieve the above-mentioned purpose, on the one hand, the present invention provides an assembled floor radiant heating system, including a radiant heating layer arranged between the floor and the slab, the radiant heating layer including a plurality of floor modules laid above the slab, each of the floor modules being connected end to end and laid to form a pipeline for assembling a heating pipe; the floor modules including a standard module 1 laid on a straight section of the pipeline and a standard module 2 laid at a bend of the pipeline, the upper center of the standard module 1 and the standard module 2 are both provided with a pre-buried groove running along the central axis thereof, each of the pre-buried grooves being connected end to end to form a continuous pipeline groove for accommodating the heating pipe; the gap formed after each of the floor modules is laid forms a first air channel, and the first air channel passes through the skirting located on the inner side of the building wall to the indoor room.

[0008] As an optional manner, the standard module 1 is a long strip structure with a trapezoidal cross section, and the standard module 2 is a quarter-circular ring strip structure with a trapezoidal cross section.

[0009] As an optional manner, a cavity 1 extending along the central axis of the bottom of each of the standard modules 1 and the standard modules 2 is opened, and each of the cavities is connected end to end to form a continuous second air channel.

[0010] As an optional manner, a cavity 2 perpendicular to the central axis is opened at the bottom of the plurality of standard modules 1 and the standard module 2, and the cavity 2 is connected to the first air channel and the second air channel.

[0011] As an optional method, the skirting board is spliced ​​by several skirting board boxes. The skirting board boxes located at the bottom of the two opposite building walls are hollow inside and pass through the first air channel and the room, and a fan facing the room is provided in the inner cavity of the skirting board box.

[0012] As an optional method, the wind fan is a micro wind fan with a power of 13W and a voltage of 220V, and the micro wind fan is also electrically connected to a solar cell panel located outside the building wall.

[0013] As an optional manner, a cement mortar self-flowing leveling layer, a thermal insulation layer and a reflective film layer stacked in sequence from bottom to top are further provided between the floor slab and the radiant heating layer.

[0014] As an optional approach, a sound insulation layer is provided at the bottom of the floor module.

[0015] As an optional manner, an upper layer of cement mortar is laid between the floor module and the floor.

[0016] On the other hand, the present invention provides a construction method of an assembled floor radiant heating system, which is used for the construction of any of the assembled floor radiant heating systems described above, and the construction method comprises the following steps:

[0017] Step S1, preparing the construction site and construction materials;

[0018] Step S2, laying the base material on the floor surface;

[0019] Step S3, laying the prefabricated floor modules on the bottom material according to the designed heating pipe direction to form a serpentine or meander-shaped circulation pipeline;

[0020] Step S4, placing a heating pipe in the pre-buried groove of the floor module;

[0021] Step S5, installing a skirting box around the building wall, and installing a fan in the designated skirting box, and connecting the fan power supply, which can be an independent power supply, room power or solar power supply;

[0022] Step S6: Test the system to ensure that the heating and ventilation systems operate normally.

[0023] The present invention has the following technical effects: The assembled floor radiant heating system and its construction method of the present invention achieve the technical effects of environmental protection, energy saving, low cost and high efficiency heat exchange through innovative structural design.

DETAILED DESCRIPTION

[0040] 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.

[0041] Aiming at the problems of heat transfer, cost and the inability to generate air circulation in the existing traditional wet method and dry prefabricated groove insulation module method, a prefabricated floor radiant heating system based on mechanical enhanced convection and its construction method are proposed. The system is based on the principle of mechanical enhanced convection to achieve a more environmentally friendly, energy-saving and low-carbon building goal.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an assembled floor radiation heating system, comprising a beam 1, a floor slab 2, a cement mortar self-flowing leveling layer 3, a thermal insulation layer 4, a reflective film layer 5, a sound insulation layer 6, a radiation heating layer, an upper cement mortar 9, and a floor 8, which are arranged in sequence from bottom to top; wherein the cement mortar self-flowing leveling layer 3, the thermal insulation layer 4, and the reflective film layer 5 are all paved layers covering the entire floor 8, the radiation heating layer comprises a plurality of floor modules 7 located above the reflective film layer 5, and an air layer formed by the intervals of the floor modules 7, and a sound insulation layer 6 is arranged between the bottom of the floor module 7 and the reflective film layer 5; the plurality of floor modules 7 are laid end to end in the form of a pipeline; a pre- The embedded grooves 71, the pre-buried grooves 71 on each floor module 7 are also connected end to end to form a continuous pipeline groove for accommodating the heating pipe 11, and the heating pipe 11 is placed in the pipeline groove; each floor module 7 is arranged according to the laying direction of the heating pipe 11, and a serpentine pipeline or a meandering pipeline is laid on the reflective film layer 5, and a first air channel 10 is formed between two adjacent rows of pipelines; a skirting board is arranged above the floor 8 along the building wall 12, and the skirting board is spliced ​​by a plurality of skirting board boxes 13, and the skirting board box 13 is a hollow structure with a hollow interior that can accommodate air passing through; a plurality of fans are also arranged in the two rows of skirting boards on the opposite sides, and the fans are arranged on the side or top of the skirting board box 13, which is used to form gas exchange between the room and the radiant heating layer.

[0044] In the above embodiment, the floor module 7 is divided into a standard module 1 7a and a standard module 2 7b. Figure 3 and Figure 4 As shown, in some embodiments, the central area of ​​the upper surface of the standard module 1 7a and the standard module 2 7b is provided with a pre-buried groove 71 along its length direction. The standard module 1 7a is a long strip structure with a trapezoidal cross-section, which is used to splice rows of pipelines, and the standard module 2 7b is a quarter-circular strip structure with a trapezoidal cross-section, which is used to connect the ends of two adjacent rows of pipelines.

[0045] like Figure 5 and Figure 6As shown, in some embodiments, a pre-buried groove 71 is opened along its length direction in the central area of ​​the upper surface of the standard module 1 7a, and a cavity 1 72 is opened along its length direction in the central area of ​​the lower surface; a pre-buried groove 71 is opened along its arc direction in the central area of ​​the upper surface of the standard module 2 7b, and a cavity 1 72 is opened along its arc direction in the central area of ​​the lower surface; after the standard modules 1 7a and 2 7b are spliced, the pre-buried grooves 71 are connected end to end to form a continuous pipeline groove for accommodating the heating pipe 11, and the cavities 1 72 are connected end to end to form a second air channel 15 consistent with the direction of the pipeline groove. The first air channel 10 and the second air channel 15 together form an air interlayer. There is air in the air interlayer. Due to the large thermal resistance of air, the heat transfer to the surrounding area and the bottom floor 2 will be reduced. Combined with the bottom insulation layer 4, it can have a good insulation effect on the indoor environment.

[0046] like Figure 7 and Figure 8 As shown, in some embodiments, the central area of ​​the upper surface of the standard module 1 7a is provided with a pre-buried groove 71 along its length direction, the central area of ​​the lower surface is provided with a cavity 1 72 along its length direction, and the central area of ​​the side surface of the lower surface is provided with a cavity 2 73 along its width direction; similarly, the central area of ​​the upper surface of the standard module 2 7b is provided with a pre-buried groove 71 along its arc direction, the central area of ​​the lower surface is provided with a cavity 1 72 along its arc direction, and the central area of ​​the side surface of the lower surface is provided with a cavity 2 73 along the radial direction of the arc; each of the cavities 2 73 is used to connect the first air channel 10 and the second air channel 15, which can achieve the effect of ventilation and faster heat transfer to the room.

[0047] It should be understood that, in actual applications, the advantage of each floor module 7 (including standard module 1 7a and standard module 2 7b) in terms of construction is that it can be prefabricated in advance in the factory according to user needs. When ready for construction, the floor module 7 is transported from the factory to the construction site, and the floor module 7 is laid at the designated position according to the designed direction of the heating pipe 11. After the laying is completed, the heating pipe 11 is buried in the pre-buried groove 71.

[0048] In the above embodiment, the skirting line is formed by splicing a plurality of skirting line boxes 13, such as Fig. 9 and Fig.10 As shown, the skirting box 13 is a hollow structure with a hollow interior that can accommodate air passing through; a fan is installed in some skirting boxes 13, for example, a plurality of fans are installed in two rows of skirtings on two opposite sides of the room, and the skirtings on the other two sides are spliced ​​by skirting boxes 13 without fans installed. The fan can be installed on the side or top of the skirting box 13 to form gas exchange between the room and the radiant heating layer. Fig. 9 and Fig.10The present invention shows a structural example in which a fan is arranged on the side of a skirting box 13, wherein the skirting box 13 is hollow inside and includes an upper cavity 131 and a lower cavity 132 which are connected from top to bottom, and the upper cavity 131 and the lower cavity 132 have upper and lower air outlets facing the same side, and the fan is installed in the upper cavity 131. The air outlet of the upper cavity 131 is installed with a grid (not shown in the figure), and the lower air outlet is used to penetrate the air layer, thereby transferring the heat of the radiant heating layer from the lower cavity 132 and the upper cavity 131 to the room, forming ventilation and heat exchange.

[0049] In some embodiments, the fan can be a micro fan 14 with a voltage of 220V, a power of 13W, and a length, height and thickness of 100mm×100mm×25mm.

[0050] In some embodiments, the wind turbine can be powered by an independent power supply, by indoor electricity, or by solar energy. When solar energy is used for power supply, a solar panel for converting sunlight into electrical energy is arranged on the outer wall of the building. The solar panel is connected to a junction box, an inverter, and a control box, and is electrically connected to each wind turbine. Of course, the solar panel is also connected to a battery for storing excess electricity in the battery for use at night.

[0051] like Fig.11 and Fig.12 As shown, the embodiment of the present invention provides two laying methods of floor heating coils, wherein: Fig.11 The parallel pipeline laying method is shown. Fig.12 The zigzag pipeline laying method is shown. The above two laying methods are the only forms of laying methods for floor heating coils in residential buildings. The standard module 1 7a and the standard module 2 7b disclosed in the embodiment of the present invention can well realize the above two laying forms. Specifically, after the user specifies the pipe spacing, pipe diameter, distance from the wall and laying type, the construction personnel can transport the matching floor module 7 to the construction site according to the user's needs, and assemble and connect them at the construction site, which is convenient and quick.

[0052] According to the two floor heating coil laying methods of parallel pipeline laying method and roundabout pipeline laying method, the embodiment of the present invention provides two solutions for laying floor heating coils based on parallel pipelines, respectively referring to Fig.13 and Fig.14 , Fig.13 and Fig.14 Two combinations of skirting modules and fans are shown to solve the problem of air ventilation in the air layer of the floor module 7. The two solutions are: Fig.13 The two-way suction type shown Fig.14 Bidirectional press-in type shown.

[0053] exist Fig.13 and Fig.14In the figure, the direction indicated by the arrow is the direction of gas flow. The standard module 1 7a and the standard module 2 7b marked with reference numbers in the figure (the standard module 1 7a and the standard module 2 7b shown in gray lines in the figure) are floor modules 7 with cavity 2 73, and the remaining floor modules 7 (the standard module 1 7a and the standard module 2 7b not marked with reference numbers and black lines in the figure) all use floor modules 7 without cavity 2 73.

[0054] like Fig.13 As shown, in this two-way suction scheme, two opposite sides (the front side and the back side in the figure) are selected from the four sides of the room, and a fan is arranged on the side of each skirting box 13 of the two walls, and the skirtings of the other two walls (left and right sides) are solid and closed. After the fan is started, the fan on one side continuously sucks in the indoor air, and the indoor air is sent to the radiation heating layer along the hollow area inside the skirting box 13. At this time, the air entering the radiation heating layer will be divided into two branches, one of which pushes the air outside the air layer to flow directly from the hollow skirting side into the room; the other branch will enter the central area of ​​the radiation heating layer from the cavity 2 73 of the standard module 1 7a, push the air in the central area of ​​the floor module 7 to flow along the first air channel 10 inside, and finally flow out from the cavity 2 73 of the standard module 2 7b on the front side, and finally enter the hollow area inside the front skirting. The fan on the other side drives the gas in the air layer to flow out, so that the gas in the air layer enters the room, so that one suction and one extraction form a wind cycle.

[0055] like Fig.14 As shown, in this two-way push-in solution, two opposite sides are selected from the four sides of the room, such as a fan is arranged on the side of each skirting box 13 on the front and rear walls, and the skirting boxes 13 on the other two sides (i.e., the left and right sides) are hollow so that air can flow in and out freely. After the fan is started, the fans on both sides continuously inhale the indoor air, and the indoor air is sent to the radiant heating layer along the hollow area inside the skirting box 13. At this time, the air entering the radiant heating layer will be divided into two branches, one of which pushes the air outside the air interlayer to flow directly from the hollow skirting side into the room, and the other pushes the air inside the floor module 7 to flow along the internal wind duct, and finally enters the internal hollow area of ​​the skirting box 13 on the left and right sides from the cavity 2 73 of the standard module 1 7a on the left and right sides of the figure, and then flows into the room to form a wind circulation.

[0056] It should be understood that in actual construction, the position of the second cavity 73 in the standard module 1 7a can form a variety of air duct forms according to user needs. The embodiment of the present invention only provides an optional implementation method and is not intended to limit the present invention.

[0057] The assembled floor radiant heating system disclosed in the above embodiments has the following technical advances:

[0058] In terms of heat transfer, since there is gas (such as air) in the air layer formed by the first air channel 10 and the second air channel 15, it has a high thermal resistance, which helps to reduce the transfer of heat to the surrounding environment and the floor 2. The use of the insulation board can further enhance the indoor insulation effect and keep the indoor temperature stable. The reflective film can reflect heat and reduce the transfer of heat to the floor.

[0059] In terms of ventilation, through carefully designed pipe laying, specific air ducts can be formed within the 7 layers of floor module. These air ducts can be adjusted through different combinations of skirting boxes and fans to control the heat in the air interlayer entering the room, thus achieving effective air circulation.

[0060] In terms of economy, the floor module 7 is made of gypsum material, which is not only energy-saving and environmentally friendly, but also low in cost. During the construction process, the reflective film is only laid in the air interlayer, which can reduce the use of materials and reduce costs. Compared with the traditional wet construction method, this modular floor has better heat transfer performance, and at the same time, it is lower in construction cost and less difficult than the prefabricated groove module.

[0061] In terms of sound insulation, the sound insulation layer 6 uses a sound insulation pad, which can effectively reduce the vibration between different surface layers and reduce the propagation of impact sound. This design helps to improve the sound insulation effect of the room and provide a quieter indoor environment for the occupants.

[0062] The present invention also provides a construction method of an assembled floor radiant heating system, which is used for the construction of the assembled floor radiant heating system. The construction method comprises the following steps:

[0063] Step S1, prepare the construction site and ensure that all prefabricated floor modules 7, heating pipes 11 and other materials are ready.

[0064] Step S2, laying the bottom material on the surface of the floor 2; wherein step S2 includes:

[0065] Step S201, laying a cement mortar self-flowing leveling layer 3 on the surface of the floor 2;

[0066] Step S202: Lay the thermal insulation layer 4 on the cement mortar self-flowing leveling layer 3, and lay the reflective film layer 5 thereon.

[0067] Step S203 , laying a sound insulation layer 6 on the reflective film layer 5 .

[0068] Step S3: Lay the prefabricated floor module 7 on the sound insulation layer 6 according to the designed direction of the heating pipe 11 to form a serpentine or meandering pipeline.

[0069] Step S4, placing the heating pipe 11 in the pre-buried groove 71 of the floor module 7; selecting a parallel or circular pipeline laying method to lay the floor heating coil as needed.

[0070] Step S5, installing a skirting box 13 around the building wall 12, and installing a micro fan 14 in the designated skirting box 13; connecting the fan power supply, which can be an independent power supply, room power or solar power supply.

[0071] Step S6: After completing the above steps, test the system to ensure that the heating and ventilation systems operate normally.

[0072] Compared with the prior art, the assembled floor radiant heating system and the construction method thereof disclosed in the embodiments of the present invention have at least the following beneficial effects:

[0073] 1. Meet the green energy-saving, environmental protection and low-carbon standards required by the country and the requirements of the "Assembled Building Evaluation Standard" (GB / T51129-2017).

[0074] 2. The floor modules are prefabricated in the factory and can be assembled directly on site. The construction is quick, convenient and has low requirements.

[0075] 3. An air layer will be formed between the floor modules. The air thermal resistance in the air layer is large, which reduces the transfer of heat to the surrounding environment, reduces heat dissipation, and provides more heat for the room.

[0076] 4. The combination of micro fans and skirting boxes can effectively promote the flow of air in the air layer, so that the air in the room and the floor module forms an air circulation, enhances the convection heat transfer effect, makes the room warmer, and produces a suitable breeze.

[0077] The details not described in detail in the present invention are all conventional technical means well known to those skilled in the art.

[0079] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention.
