An active adaptive energy-saving exterior wall and method

Abstract

The invention discloses an active adaptable energy-saving external wall and a method thereof. The technical proposal is as follows: a wall and a capillary network installed in the thermal insulation layer outside the wall, the top and bottom of the capillary network are respectively connected to a capillary main pipe; One end of the main pipe is connected to the first indoor pipe, and the other end is connected to the first outdoor pipe; one end of the capillary main pipe at the bottom is connected to the second indoor pipe through the first axial flow fan, and the other end is connected to the second outdoor pipe through the second axial flow fan; The first indoor pipeline, the first outdoor pipeline, the second indoor pipeline, and the second outdoor pipeline are all equipped with valves; they also include temperature sensing devices for monitoring the indoor temperature, outdoor temperature, and capillary network temperature respectively, and the temperature sensing devices send signals to the central Control system processing, the central control system controls the first axial flow fan, the second axial flow fan and valve action. The invention can independently change the physical properties of the wall body according to the indoor and outdoor ambient temperature and the internal temperature of the wall body, so as to achieve the purpose of energy saving.

Description

technical field [0001] The invention relates to the field of construction, in particular to an active adaptive energy-saving exterior wall and a method thereof. Background technique [0002] Building energy conservation requires that the exterior walls have good thermal insulation properties. For exterior walls in cold and severe regions, it is usually necessary to add an insulation layer to meet the demand. The inventors found that after the construction of the traditional exterior wall, it is difficult to adjust its thermal insulation performance, and it is difficult to adapt to the changing external environment. For example, in summer, when the solar radiation is irradiated on the exterior wall of the building, the wall will absorb and store a large amount of heat, and transfer it into the room, significantly increasing the cooling load of the building; in winter, when there is no solar radiation, the exterior wall will Absorbs indoor heat and transfers it to the outside...

AI Technical Summary

Problems solved by technology

If the exterior wall of a building is mainly considered for thermal insulation, it has greater thermal inertia and heat storage capacity. Although it can reduce the transfer of cold and heat between indoor and outdoor environments, it will absorb a large amount of solar radiation and store it in summer; In winter, a large amount of indoor heat will be absorbed and stored, increasing the cooling load of the building during subsequent operation
