A capillary phase-change thermal insulation piece, a building wall including the same, and a building

Abstract

The invention discloses a capillary tube phase change insulation part, a building wall comprising the same and a building. The capillary tube phase change insulation part is used for thermal insulation of the building wall and is characterized by comprising a phase change material, a phase change packaging body for packaging a phase change substance and a heat exchange part arranged in the phase change material, the heat exchange part and the phase change material perform contact heat exchange to adjust the temperature of the building wall, and the heat exchange part comprises at least one first capillary tube arranged in the phase change material.

Description

technical field [0001] The invention relates to a capillary phase change thermal insulation part, a building wall and a building including the same, and belongs to the field of construction. Background technique [0002] With the development of phase change materials, the technology of filling phase change materials into the envelope structure as the insulation layer of building walls has matured, and the products on the market have been promoted. The products on the market include hollow brick filling technology, phase change exterior Adhesive wall, PCM microcapsule technology. Due to its unique thermal properties (phase change endothermic), phase change materials can smooth house temperature changes, absorb external heat, and even store energy. This technology can be used to reduce building energy consumption. At the same time, PCM is an environmentally friendly material that can further optimize the environment. . [0003] However, as a phase change material for heat pr...

Problems solved by technology

[0003] However, as a phase change material for heat preservation and heat storage, the phase change will only occur under certain temperature conditions. The change in the external temperature must make the phase change material alternately change between solid and liquid in order to exert its heat absorption or In this way, when the daytime and nighttime temperatures are very low in winter and the daytime and nighttime temperatures are high in summer, the phase change material cannot play its role of heat preservation and energy storage well. How to make the heat preservation material It can play its heat absorption or heat release effect well under different temperature conditions, and play the role of heat preservation, which is a problem that needs to be solved at present.
