Title:

PHASE-CHANGE ENERGY STORAGE THERMAL INSULATION STRUCTURE FOR BUILDING

Document Type and Number:

WIPO Patent Application WO/2018/227879

Kind Code:

A1

Abstract:

Disclosed is a phase-change energy storage thermal insulation structure for a building, wherein a wall substrate (1), a thermal insulation layer (2), an oriented structure panel (3), a phase-change energy storage thermal insulation board (7) of a set shape and an exterior trim board (6) are successively provided in the direction from outdoors to indoors; the phase-change energy storage thermal insulation board (7) of a set shape is formed of an inorganic composite phase-change material (4) and a packaging board material (5); the inorganic composite phase-change material (4) is obtained by compounding an inorganic hydrated salt and a porous structure carrier, and the phase-change temperature of the inorganic composite phase-change material is 10°C to 40°C; in the inorganic composite phase-change material (4), the mass percentage of the inorganic hydrated salt is 40-95%; and the inorganic composite phase-change material (4) is coated with a light-cured fire- and corrosion-resistant resin. The structure has the advantages of a good thermal insulation effect, prolonging the duration of an indoor peak temperature, mitigating indoor temperature fluctuation, improving the level of comfort of an environment, and reducing the energy consumption of an air conditioner in the summer.
