Abstract
Description
Technical Field
[0001] This invention relates to the field of building heating and ventilation technology, and in particular to a prefabricated floor radiant heating system and its construction method. Background Technology
[0002] In the current field of underfloor heating and building ventilation, traditional floor construction methods have some obvious limitations, failing to fully meet national requirements for green building and energy conservation. Specifically, there are two main traditional floor construction methods: one is the wet construction method, which increases the floor thickness, significantly increasing the building load and leading to substantial heat loss. Furthermore, it has a long construction period and is very inconvenient for later maintenance; the other is the prefabricated grooved insulation module method, which can reduce heat loss to some extent, but it is more expensive, requires high construction precision, and has a poorer feel when walked on.
[0003] With the implementation of the "Evaluation Standard for Prefabricated Buildings" (GB / T 51129-2017), prefabricated buildings have begun to receive more attention. Under this standard, the main structure and enclosure wall structure have seen significant development, but progress in fully-furnished dry floor construction has been relatively slow. Traditional wet construction methods cannot meet the requirements of the new standard, while dry prefabricated trench insulation modules, although they can meet the standard, are often limited in application due to cost and construction requirements.
[0004] In terms of building ventilation, existing floor designs are mostly closed structures, lacking effective space to promote air circulation, which limits the effectiveness of floor heat exchange. Achieving air circulation within the indoor environment would help increase convective heat transfer, especially in winter, more effectively raising the indoor temperature and reducing 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 promote air circulation and meet national standards, but also have the characteristics of low cost and high-efficiency heat exchange. Summary of the Invention
[0006] The purpose of this invention is to provide a prefabricated floor radiant heating system and its construction method, in order to solve the problems of large heat loss in traditional floor construction, high cost of prefabricated grooved insulation modules, high construction requirements, and the inability to generate air circulation due to the closed structure.
[0007] To achieve the above objectives, on the one hand, the present invention provides a prefabricated floor radiant heating system, including a radiant heating layer disposed between the floor and the floor slab. The radiant heating layer includes a plurality of floor modules laid on the floor slab, and each floor module is laid end to end to form a pipeline for assembling heating pipes. Each floor module includes a standard module one laid on the straight section of the pipeline and a standard module two laid at the bend of the pipeline. Both standard module one and standard module two have a pre-embedded groove at the center of their upper surfaces, running along their central axis. Each pre-embedded groove is laid end to end to form a continuous pipeline groove for accommodating the heating pipes. The gaps formed after the floor modules are laid form a first air channel, which extends into the room through a skirting board located on the inner side of the building wall.
[0008] As an optional approach, the first standard module is a long strip structure with a trapezoidal cross-section, and the second standard module is a quarter-circular strip structure with a trapezoidal cross-section.
[0009] As an alternative, each of the standard modules I and II has a cavity I extending along its central axis at the bottom center, and the cavities are connected end to end to form a continuous second air channel.
[0010] As an alternative, the bottom of several standard modules one and standard modules two has a cavity two perpendicular to the central axis, and the cavity two connects the first air channel and the second air channel.
[0011] As an alternative, the skirting board is composed of 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 passage and the room. A fan facing the room is provided in the inner cavity of the skirting board box.
[0012] As an alternative, the fan is a miniature fan with a power of 13W and a voltage of 220V, and the miniature fan is also electrically connected to solar panels located on the exterior of the building wall.
[0013] As an alternative, a cement mortar self-leveling layer, an insulation layer, and a reflective film layer, stacked sequentially from bottom to top, are also provided between the floor slab and the radiant heating layer.
[0014] As an alternative, the floor module has a sound-insulating layer at its bottom.
[0015] As an alternative, a 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 for a prefabricated floor radiant heating system, used for the construction of the prefabricated floor radiant heating system described in any of the above claims, the construction method comprising the following steps:
[0017] Step S1: Prepare the construction site and construction materials;
[0018] Step S2: Lay the base material on the floor slab surface;
[0019] Step S3: Lay the prefabricated floor modules on the base material according to the designed heating pipe route to form a serpentine or loop-shaped circulation pipeline.
[0020] Step S4: Place the heating pipes in the pre-embedded trenches of the floor module;
[0021] Step S5: Install skirting box around the building wall and install a fan in the designated skirting box. Connect the fan to a power source, which can be an independent power source, indoor electricity, or solar power.
[0022] Step S6: Test the system to ensure that the heating and ventilation systems are functioning properly.
[0023] This invention offers the following technical advantages: The prefabricated floor radiant heating system and its construction method, through innovative structural design, achieve environmentally friendly, energy-saving, low-cost, and highly efficient heat exchange. The system reduces heat dissipation by forming an air gap and enhances air circulation and convective heat transfer using a combination of micro-fans and baseboard boxes, thereby improving indoor temperature and comfort. Simultaneously, the prefabricated floor modules simplify the construction process, reduce costs and construction difficulty, and meet national green building and energy conservation and environmental protection requirements.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] To address the issues of heat transfer, cost, and lack of air circulation caused by the closed structure of existing traditional wet and dry prefabricated trench insulation modules, this paper proposes a prefabricated floor radiant heating system and its construction method based on mechanically enhanced convection. This system is based on the principle of mechanically enhanced convection to achieve more environmentally friendly, energy-saving, and low-carbon building goals.
[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0043] Reference Figure 1 and Figure 2 As shown, this embodiment of the invention provides a prefabricated floor radiant heating system, comprising, from bottom to top, a beam 1, a floor slab 2, a cement mortar self-leveling layer 3, an insulation layer 4, a reflective film layer 5, a sound insulation layer 6, a radiant heating layer, an upper cement mortar layer 9, and a floor 8; wherein, the cement mortar self-leveling layer 3, the insulation layer 4, and the reflective film layer 5 are all laying layers covering the entire floor 8; the radiant heating layer includes several floor modules 7 located above the reflective film layer 5, and an air gap layer formed by the floor modules 7; a sound insulation layer 6 is provided between the bottom of the floor modules 7 and the reflective film layer 5; the several floor modules 7 are laid end to end in a pipeline-like manner; a pre-fabricated structure along the length direction is provided above each floor module 7. The pre-embedded trenches 71 on each floor module 7 are connected end to end to form a continuous pipeline trough to accommodate the heating pipes 11. The heating pipes 11 are placed in the pipeline trough. Each floor module 7 is set according to the direction of the heating pipes 11. A serpentine or loop-shaped 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 set above the floor 8 along the building wall 12. The skirting board is spliced together by several skirting board boxes 13. The skirting board box 13 is a hollow structure that can accommodate air. Several fans are also installed in the two rows of skirting boards on opposite sides. The fans are set on the side or top of the skirting board box 13 to form gas exchange between the room and the radiant heating layer.
[0044] In the above embodiments, the floor module 7 is divided into standard module one 7a and standard module two 7b, as follows: Figure 3 and Figure 4 As shown, in some embodiments, the upper surface center areas of standard module 1 7a and standard module 2 7b are both provided with pre-embedded grooves 71 along their length direction. Standard module 1 7a is a long strip structure with a trapezoidal cross section, used to splice rows of pipelines. Standard module 2 7b is a quarter-circular strip structure with a trapezoidal cross section, used to connect the ends of adjacent rows of pipelines.
[0045] like Figure 5 and Figure 6As shown, in some embodiments, the upper surface of standard module 7a has a pre-embedded groove 71 along its length in the central area, and the lower surface has a cavity 72 along its length in the central area; the upper surface of standard module 7b has a pre-embedded groove 71 along its arc direction in the central area, and the lower surface has a cavity 72 along its arc direction in the central area; after the standard modules 7a and 7b are spliced together, the pre-embedded grooves 71 are connected end to end to form a continuous pipeline groove for accommodating the heating pipe 11, and the cavities 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 gap layer. The air gap layer contains air. Due to the high thermal resistance of air, it reduces the heat transfer to the surrounding area and the bottom floor slab 2. Combined with the bottom insulation layer 4, it can achieve a good heat preservation effect for the indoor environment.
[0046] like Figure 7 and Figure 8 As shown, in some embodiments, the upper surface of standard module 7a has a pre-embedded groove 71 along its length in the central region, the lower surface has a cavity 72 along its length in the central region, and the lower surface has a cavity 73 along its width in the central region of its side surface; similarly, the upper surface of standard module 7b has a pre-embedded groove 71 along its arc direction in the central region, the lower surface has a cavity 72 along its arc direction in the central region, and the lower surface has a cavity 73 along its arc radial direction in the central region of its side surface; each cavity 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 practical applications, the advantage of each floor module 7 (including standard module 1 7a and standard module 2 7b) in terms of construction is that they can be prefabricated in the factory according to the user's needs. When it is time to prepare for construction, the floor module 7 is transported from the factory to the construction site. According to the designed route of the heating pipes 11, the floor module 7 is laid in the designated position. After the laying is completed, the heating pipes 11 are buried in the pre-buried trench 71.
[0048] In the above embodiment, the baseboard is composed of several baseboard boxes 13 joined together, such as Figure 9 and Figure 10 As shown, the skirting board box 13 is a hollow structure with an internal cavity that allows air to pass through. A fan is installed in some of the skirting board boxes 13; for example, several fans are installed in two rows of skirting boards on opposite sides of the room, while the skirting boards on the other two sides are joined together by skirting board boxes 13 without fans. The fans can be located on the side or top of the skirting board box 13 to facilitate air exchange between the room and the radiant heating layer. Figure 9 and Figure 10An example of a structure with a fan installed on the side of a skirting box 13 is shown. The skirting box 13 is hollow inside and includes an upper cavity 131 and a lower cavity 132 that are connected vertically. The upper cavity 131 and the lower cavity 132 have two air vents facing the same side. The fan is installed in the upper cavity 131. The air vent of the upper cavity 131 is equipped with a grid (not shown in the figure). The lower air vent is used to communicate with the air gap 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 may be a miniature fan 14 with a voltage of 220V, a power of 13W, and dimensions of 100mm×100mm×25mm.
[0050] In some embodiments, the wind turbines can be powered by an independent power source, by indoor electricity, or by solar energy. When solar power is selected, solar panels for converting sunlight into electrical energy are installed on the exterior walls of the building. The solar panels are connected to a combiner box, inverter, and control box, and are electrically connected to each wind turbine. Of course, the solar panels are also connected to batteries to store excess electricity for nighttime use.
[0051] like Figure 11 and Figure 12 As shown, embodiments of the present invention provide two methods for laying underfloor heating coils, wherein, Figure 11 This illustrates a parallel pipeline laying method. Figure 12 The diagram illustrates a loop-shaped pipe laying method. The two laying methods described above are the main forms of underfloor heating pipe laying in residential buildings. The standard module 7a and standard module 7b disclosed in this embodiment of the invention can effectively implement these two laying methods. Specifically, after the user specifies the pipe spacing, pipe diameter, distance from the wall, and laying type, construction personnel can transport the matching floor modules 7 to the construction site according to the user's needs and assemble and connect them on-site, which is convenient and quick.
[0052] Based on two methods of laying underfloor heating coils—parallel pipeline laying and loop pipeline laying—this invention provides two solutions for laying underfloor heating coils based on parallel pipeline laying, respectively referring to… Figure 13 and Figure 14 , Figure 13 and Figure 14 Two solutions combining skirting board modules and fans are shown to address the air ventilation problem in the air gap of floor module 7. The two solutions are as follows: Figure 13 The bidirectional suction type shown Figure 14 The bidirectional push-in type is shown.
[0053] exist Figure 13 and Figure 14In the figure, the arrows indicate the direction of gas flow. Standard module 1 7a and standard module 2 7b marked with the attached icon (standard module 1 7a and standard module 2 7b shown by the gray lines in the figure) are floor modules 7 with cavity 2 73. The remaining floor modules 7 (standard module 1 7a and standard module 2 7b without the attached icon and shown by the black lines in the figure) are all floor modules 7 without cavity 2 73.
[0054] like Figure 13 As shown, in this bidirectional suction design, two opposite sides (the front and back sides in the diagram) are selected from the four sides of the room. A fan is installed on each side of the baseboard box 13 on both sides. The baseboards on the other two sides (left and right) are solid and sealed. After the fans are started, one fan continuously draws in indoor air. The indoor air is sent into the radiant heating layer along the hollow area inside the baseboard box 13. The air entering the radiant heating layer then splits into two streams: one stream pushes the air outside the air gap directly into the room from the hollow baseboard side; the other stream enters the central area of the radiant heating layer from the cavity 73 of standard module 1 7a, pushing the air in the central area of floor module 7 along the internal first air channel 10, and finally flows out from the cavity 73 of the front standard module 2 7b, and finally enters the hollow area inside the front baseboard. The other fan drives the gas in the air gap to flow out, allowing the gas in the air gap to enter the room. This suction and extraction creates a wind circulation.
[0055] like Figure 14 As shown, in this bidirectional forced-in system, two opposite sides are selected from the four sides of the room, such as the front and back walls, each baseboard box 13 has a fan installed on its side. The other two sides (i.e., the left and right sides) have hollow baseboard boxes 13 to allow air to flow freely in and out. After the fans are started, the fans on both sides continuously draw in indoor air. The indoor air is sent into the radiant heating layer along the hollow area inside the baseboard box 13. At this time, the air entering the radiant heating layer will be divided into two branches. One branch pushes the air outside the air gap layer directly into the room from the hollow baseboard side, and the other branch pushes the air inside the floor module 7 to flow along the internal air duct. Finally, it enters the hollow area inside the baseboard box 13 from the cavity 73 of the standard module 7a on the left and right sides of the figure, and then flows into the room, forming an air circulation.
[0056] It should be understood that in actual construction, the position of cavity 73 in standard module 7a can be configured into various air duct forms according to user needs. This embodiment of the invention only provides an optional implementation method and is not intended to limit the invention.
[0057] The prefabricated floor radiant heating system disclosed in the above embodiments has the following technological advancements:
[0058] In terms of heat transfer, the air gap formed by the first air channel 10 and the second air channel 15 contains gas (such as air), which has a high thermal resistance. This helps reduce heat transfer to the surrounding environment and floor slab 2. The use of insulation boards can further enhance the indoor insulation effect and maintain a stable indoor temperature. The reflective film can reflect heat and reduce heat transfer towards the floor slab.
[0059] In terms of ventilation, a specific air duct can be formed within the seven layers of floor modules through carefully designed ductwork. These air ducts can be adjusted using different combinations of baseboard boxes and fans to control the entry of heat from the air gaps into the room, thereby achieving effective air circulation.
[0060] In terms of economy, floor module 7 uses gypsum board, a material that is not only energy-efficient and environmentally friendly but also low-cost. During construction, the reflective film is only laid within the air gap, reducing material usage and lowering costs. Compared to traditional wet construction methods, this modular floor offers superior heat transfer performance and is also less expensive and easier to install than prefabricated grooved modules.
[0061] In terms of sound insulation, sound insulation layer 6 uses sound-absorbing pads, which can effectively reduce vibration between different surface layers and reduce the propagation of impact sound. This design helps to improve the sound insulation of the room, providing residents with a quieter indoor environment.
[0062] This invention also provides a construction method for a prefabricated floor radiant heating system, used for the construction of the aforementioned prefabricated floor radiant heating system, the construction method comprising 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: Lay the base material on the surface of floor slab 2; wherein step S2 includes:
[0065] Step S201: Lay a cement mortar self-leveling layer 3 on the surface of floor slab 2;
[0066] Step S202: Lay the insulation layer 4 on the cement mortar self-leveling layer 3, and then lay the reflective film layer 5 on it.
[0067] Step S203: Lay a sound insulation layer 6 on the reflective film layer 5.
[0068] Step S3: Lay the prefabricated floor modules 7 on the sound insulation layer 6 according to the designed heating pipe 11 route to form a serpentine or loop-shaped pipeline.
[0069] Step S4: Place the heating pipe 11 in the pre-embedded trench 71 of the floor module 7; select a parallel or loop pipeline laying method as needed to lay the underfloor heating coil.
[0070] Step S5: Install skirting box 13 around the building wall 12, and install miniature fan 14 in the designated skirting box 13; connect the fan to the power supply, which can be an independent power supply, indoor power, or solar power.
[0071] Step S6: After completing the above steps, test the system to ensure that the heating and ventilation system is operating normally.
[0072] The prefabricated floor radiant heating system and its construction method disclosed in this invention have at least the following beneficial effects compared to the prior art:
[0073] 1. Meet the national green, energy-saving, environmentally friendly and low-carbon standards and the requirements of the "Evaluation Standard for Prefabricated Buildings" (GB / T51129-2017).
[0074] 2. The floor modules are prefabricated in the factory and can be directly assembled on site, making construction quick, convenient and with low requirements.
[0075] 3. An air gap is formed between the floor modules. The air in the air gap has a high thermal resistance, which reduces the transfer of heat to the surrounding environment and the dissipation of heat, thus providing more heat to the room.
[0076] 4. The combination of a miniature fan and a baseboard box effectively promotes airflow within the air gap, creating an air circulation between the room and the floor module. This enhances convective heat transfer, making the room warmer and creating a pleasant breeze.
[0077] All aspects not detailed in this invention are conventional technical means well known to those skilled in the art.
