Phase-change energy storage composite heat supply wallboard

Abstract

The invention relates to a phase-change energy storage composite heating wallboard, which comprises a bottom plate, a thermal insulation board, a phase-change energy storage board and a surface decoration board arranged sequentially from bottom to top. The energy plate is sealed and bonded, and the upper end of the phase change energy storage plate is sealed and bonded to the surface decoration plate; the phase change energy storage plate includes a honeycomb plate, and a number of phase change units that are independently sealed from each other are formed in the honeycomb plate, All or part of the phase change unit is filled with a phase change energy storage material. The addition of the phase change material enables the honeycomb panel to effectively utilize the phase change energy storage performance of the phase change material, which can automatically adjust the temperature of the building, and overcomes many shortcomings of using the phase change material for energy storage and heat preservation in the prior art. The invention has the advantages of simple preparation, strong practicability, good effect and excellent market application prospect.

Description

Technical field [0001] The invention relates to a phase change energy storage composite heating wallboard. Background technique [0002] Phase-change energy storage building materials are composed of phase-change materials (PCMs) and building carrier matrix, which have excellent energy storage and release capabilities; compared with ordinary building insulation materials, they have higher heat capacity and thermal inertia. When the microenvironment temperature of the phase change material is lower than the phase change point, the phase change material condenses from liquid to solid, forming heat release; when the microenvironment temperature of the phase change material is higher than the phase change point, the phase change material changes from solid Melt into a liquid state, forming an endothermic. Through this energy storage, the purpose of maintaining room temperature, energy saving and emission reduction is achieved. [0003] At present, the wallboards used indoors are all ...

AI Technical Summary

Problems solved by technology

[0003] At present, the wallboards used indoors are all ordinary wallboards, and some of them will use heating wallboards. The heating is realized through the heating layer set in the wallboards. It is more energy-consuming to adjust the temperature by electricity.
