[0002] From the late 20th century to the early 21st century, with socioeconomic development and improved living standards, the demand for indoor comfort has become increasingly stringent. Heating, ventilation, and air conditioning (HVAC) energy consumption accounts for approximately 50% of a building's total energy consumption, making reducing HVAC energy consumption a key component of building energy conservation and emission reduction. In cold regions, heating systems are an integral part of residential and commercial buildings. Traditional heating methods, such as convection heating systems, typically heat the air to raise indoor temperatures. However, this heating method suffers from low thermal efficiency, poor comfort, and high energy consumption. Among existing technologies, low-temperature radiant floor heating systems have garnered widespread attention due to their high energy efficiency and excellent thermal comfort. This system installs heating pipes in the floor, utilizing hot water or electricity as a heat source, and transfers heat indoors through radiation. This heating method offers advantages such as uniform heat distribution, significant energy savings, and a small footprint. However, despite the above advantages, in actual applications, the existing low-temperature floor radiant heating system also has limitations in thermal response speed. Since heat is mainly transferred through the concrete layer of the ground, it takes a long time for the system to reach the set temperature or adjust the temperature. The room temperature fluctuates up and down. At the same time, heat loss is serious and energy utilization is low.

[0003] To address the above issues, patent document CN201920462071.1 discloses a low-temperature hot water floor radiant heating floor structure.

The heating pipes are wrapped by a filling layer laid on the composite protective layer, a waterproof layer is laid on the filling layer, a leveling layer is provided on the waterproof layer, and a floor decoration layer is laid on the leveling layer. However, the heating system has low energy efficiency, low energy utilization, and room temperature fluctuations. Utility Model Content

[0013] Further, the heating pipe laid in the cement mortar filling layer is arranged in S shape.

[0014] Further, the critical temperature of phase change energy storage layer is 32 DEG C, when temperature exceeds 32 DEG C, phase change material becomes liquid, and is solid at normal temperature.

[0018] Overall, compared with the prior art, the above technical scheme conceived by the utility model can achieve the following beneficial effects:

Similarly, when the floor heating is working, the heat released by the heating pipe will also cause the phase change material to heat up. When the temperature of the material exceeds the phase change temperature of 32°C due to continuous temperature increase, the material changes from solid to liquid. In this process, the material stores heat. After the floor heating system reaches the set temperature, it automatically shuts down. Subsequently, the heat stored in the material in the early stage is slowly released to the heating room, thereby reducing the operating time of the floor heating and solving the problems of poor heating effect and high heating energy consumption.

[0026] like Figure 1As shown, the utility model provides a low-temperature floor radiant heating ground structure, including an exterior wall insulation module, a floor insulation module, a heating module, an energy storage module and a decorative module, wherein the exterior wall insulation module includes an exterior wall 1, a plaster layer 3 provided on the inner side of the exterior wall 1, a boundary insulation layer 4 is provided on the inner side of the plaster layer 3, which is used for thermal insulation of the exterior wall, reducing indoor and outdoor heat exchange, improving energy efficiency and reducing energy consumption, the floor insulation module includes a floor 2, an insulation layer 6 provided on the upper part of the floor 2, which is used for thermal insulation of the floor, reducing heat transfer between floors and improving indoor temperature stability, the heating module includes a cement mortar filling layer 9 provided on the upper part of the insulation layer 6, a heating pipe 10 is provided in the cement mortar filling layer 9, a steel mesh 8 is provided at the bottom of the heating pipe 10, and the outside of the heating pipe 10 is made of cement mortar laid on the steel mesh 8 The filling layer 9 is wrapped and fixed with the steel mesh 8. The energy storage module includes a phase change energy storage layer 11 arranged on the upper part of the cement mortar filling layer 9, and a cement mortar protective layer 12 is provided on the phase change energy storage layer 11. The decorative module includes a leveling layer 13 arranged on the upper part of the cement mortar protective layer 12, and a decorative surface layer 14 is laid on the leveling layer 13. By laying the phase change energy storage layer 11 and the cement mortar protective layer 12 on the cement mortar filling layer 9, it can utilize the phase change energy storage material to absorb or release a large amount of heat during the phase change process, thereby playing a peak-shaving role in the heating system and improving the thermal efficiency and economy of the system. A cement mortar protective layer 12 is provided on the phase change energy storage layer 11, and the leveling layer 13 is used to provide a flat base for the decorative surface layer 14. This layered treatment not only protects the phase change energy storage layer 11, but also ensures the beauty and comfort of the decorative surface layer 14.

[0027] The exterior wall insulation module also includes a sealing paste 5 provided at the intersection of the top surface of the boundary insulation layer 4 and the inner side surface of the plaster layer 3 of the exterior wall 1, which is used to prevent moisture from penetrating into the floor slab, protecting the building structure from water damage, and also reducing heat loss caused by moisture penetration.

[0028] The floor insulation module also includes a protective layer 7 arranged between the insulation layer 6 and the cement mortar filling layer 9, which is made of aluminum foil. The aluminum foil surface with high reflectivity reflects heat energy, so that the heat is mainly radiated upward, thereby reducing the downward loss of heat, making the heat distribution more uniform, helping to eliminate temperature dead corners, and improving comfort. It also has good moisture-proof performance, which can prevent the rise of moisture in the floor heating system, avoid the growth of mold, and ensure the safe and stable operation of the heating system.

[0030] A phase change energy storage layer 11 is provided on the cement mortar filling layer 9. The critical temperature of the phase change energy storage layer is 32°C. When the temperature exceeds 32°C, the phase change material becomes liquid and is solid at room temperature. It liquefies and absorbs heat when the temperature is high during the day, and releases heat to ensure the temperature of the room when the temperature is low at night. Similarly, when the floor heating is working, the heat released by the heating pipe will also cause the phase change material to heat up. When the temperature of the material continues to rise and exceeds the phase change temperature of 32°C, the material changes from solid to liquid. In this process, the material stores heat, and the floor heating system automatically shuts down after reaching the set temperature. Subsequently, the heat stored in the material in the early stage is slowly released to the heating room, which reduces the running time of the floor heating and solves the problems of poor heating effect and high heating energy consumption of the floor heating. A cement mortar protective layer is provided on the phase change energy storage layer, and the leveling layer is used to provide a flat base for the decorative surface layer. This layered treatment not only protects the energy storage layer, but also ensures the beauty and comfort of the decorative surface layer.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
