Three-layer phase change insulation block

Abstract

The invention relates to a three-layer phase change insulation block, and belongs to the technical field of buildings. The three-layer phase change insulation block comprises two insulation layers, inner-layer phase change blocks, middle-layer phase change blocks, outer-layer phase change blocks, a concrete layer, insulation layer concrete ribs and phase change layer concrete ribs, wherein the two insulation layers are arranged at an interval through the insulation layer concrete ribs, one insulation layer extends to the two ends of the block, and the insulation layer concrete ribs of the two insulation layers are mutually staggered; the inner-layer phase change blocks, the middle-layer phase change blocks and the outer-layer phase change blocks are respectively arranged between the insulation layers in building blocks in an interval mode, and the inner-layer phase change blocks and the outer-layer phase change blocks are uniformly distributed in the whole internal and external concrete layer; the middle-layer phase change blocks are arranged at the position of the corresponding insulation layer concrete ribs between the two insulation layers, and the inner-layer phase change blocks, the middle-layer phase change blocks and the outer-layer phase change blocks respectively adopt different phase change materials. Under the condition that the amplitude of variation of an outdoor temperature is larger, the advantage of the phase change material that phase change energy storage is developed can be guaranteed, energy conservation and thermal insulation are realized, and the indoor temperature is stable and comfortable.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a three-layer phase-change thermal insulation block. Background technique [0002] Phase Change Materials (PCM) can absorb the heat (cold) of the environment during the phase change process, and release the heat (cold) to the environment when needed, so as to control the temperature of the surrounding environment. the goal of. Utilizing the phase change latent heat of phase change materials to realize energy storage and utilization is conducive to the development of environmentally friendly and energy-saving composite materials. It is a very active frontier research direction in the field of material science and energy utilization in recent years. Phase change energy storage building materials can be made by combining phase change materials with building material matrix. Phase change energy storage building materials are thermal functional composite materials that can store e...
