Description

Technical Field

[0001] The invention relates to the technical field of building heating, and in particular to an adjustable phase-change heat storage floor based on a heat storage heating pipe. Background Art

[0002] The adjustable phase change thermal storage floor based on thermal storage heating tubes is an innovative and efficient heating solution, especially suitable for areas with dispersed housing such as Inner Mongolia. Traditional geothermal air-conditioning systems are difficult to meet household heating needs, often resulting in waste of resources, and due to the dispersed transportation of materials, the related costs are also relatively high. The adjustable phase change thermal storage floor can effectively solve these problems. This floor uses advanced phase change materials and is optimized through the thermal storage heating tube system. It can store heat during the day and release heat at night, providing a continuous and comfortable feeling of warmth. In addition, it has strong adjustment capabilities and can be flexibly adjusted according to the actual needs of the family, avoiding the waste of traditional heating methods. This technology not only improves energy utilization efficiency, but also greatly reduces heating costs. Through this innovative heating method, residents in Inner Mongolia will be able to enjoy a more environmentally friendly and economical living experience, promoting a sustainable future.

[0003] After searching, the Chinese patent number CN209910477U discloses a phase-change heat storage floor with adjustable heating capacity, including a floor body, a cover body, a support frame, a hinge, a phase-change heat storage body and a heat insulation layer; one side of the cover body is hinged to one side of the floor body through multiple hinges, the cover body and the floor body form a closed cavity, and the support frame divides the internal space of the floor body into multiple areas; multiple independent phase-change heat storage bodies are placed in multiple areas of the floor body away from the support frame; and the outer surface of the floor body is covered with a heat insulation layer. The floor can flexibly adjust the heating capacity according to the ambient temperature and reduce the heating cost. Compared with the prior art, the Chinese patent number CN209910477U solves the problem that the heating capacity of most existing floors cannot be adjusted according to the heat load, and it is easy for the heating capacity to be greater than the heating demand, resulting in too high room temperature, and when the heat load is large, the room temperature may be low.

[0004] However, in actual use of the above device, although the floor decoration layer is provided with heat release holes, the openings of the heat release holes are fixed, and it is difficult to actively adjust the heat release of the heat release holes according to the indoor temperature. In addition, the heat supply cannot be feedback-adjusted according to the heat load. It is easy for the heat supply to be large at the beginning and end of heating, and the room temperature to be too high. When the heat load is large, the room temperature may not be guaranteed. Therefore, an adjustable phase change heat storage floor based on heat storage heating tubes is proposed. Summary of the invention
