A kind of phase change energy storage concrete and its manufacturing method

Abstract

The invention provides phase-change energy-storage concrete and a manufacturing method thereof. According to the manufacturing method, a hollow metal material device is used as a carrier of a phase-change energy-storage material, the periphery of the hollow metal material device is sealed, and a feeding hole is formed in the top of the hollow metal material device and only needs to be sealed, so that the packaging process is simple and convenient; furthermore, the metal material is hollow and high in compound quantity and thermal conductivity and can be used for preferably carrying out heat exchange, so that the energy-saving effect of the phase-change energy-storage material can be beneficially exerted, and relatively good energy storage and temperature regulation effects are achieved; a fastening device is arranged on the periphery of the metal material device, so that the surface roughness of the metal material device is enhanced, the interface adhesion between the phase-change energy-storage metal material device and hardened cement paste is improved, and the strength of the phase-change energy-storage concrete is improved. According to the phase-change energy-storage concrete and the manufacturing method, the application path of phase-change materials in the building energy-saving field is broadened, and technical support is provided for the popularization and the application of the phase-change energy-storage concrete.

Description

technical field [0001] The invention relates to the technical field of phase change energy storage, in particular to a phase change energy storage concrete and a manufacturing method thereof. Background technique [0002] Phase Change Material (Phase Change Material-PCM) refers to a substance that changes shape with temperature and can provide latent heat. When the temperature is high, the phase change material can absorb heat and store it in the form of phase change latent heat. When the temperature is low, the absorbed heat is released to realize the transfer of energy between different space-time positions It helps to alleviate the contradiction between energy supply and demand, and effectively reduces energy consumption. The application of phase change materials in the field of construction can make full use of solar energy, a renewable energy source, reduce indoor temperature fluctuations in buildings, effectively use low-peak power to shave peaks and fill valleys, opt...
