Problems solved by technology

Although the above-mentioned prior art has its own technical advantages, its shortcomings are also very obvious, mainly manifested in the inner and outer shaped phase-change wallboard layers with different phase-change temperatures, both of which are fixed on the wall. The two kinds of phase change wall panels play the role of latent heat storage and release in one season. When one phase change wall panel plays a role, the other phase change wall panel basically does not play a role in heat storage and release. hot function

Embodiment 1

[0033] Figure 2-4 and 8 are embodiment 1 of the phase change material wall body with adjustable phase change temperature of the present invention. The wall of the present invention is a building exterior wall, including a phase change material sleeve 1, a phase change material 2 for summer, a phase change material 3 for winter, heat storage and heat preservation filler 4, a wall 5, heat preservation material 6, and a rotating shaft 9 , rotating gear 10, rotating chain 11.

[0034] The phase-change material sleeve 1 is divided into two cavities that are not connected, and are respectively filled with the phase-change material 2 for summer and phase-change material 3 for winter.

[0035] The phase change material sleeve 1 is connected with the rotation shaft 9; the rotation shaft 9 is provided with a rotation gear 10 and a rotation chain 11; the rotation gear 10 can be rotated by the rotation chain 11, and then the rotation shaft 9 and the phase change material sleeve 1 are ro...

Embodiment 2

[0042] Figure 5-8 It is embodiment 2 of the phase change material wall body with adjustable phase change temperature of the present invention. The wall body of the present invention is an interior wall body of a building. The difference between the structure and Embodiment 1 is that both sides of Embodiment 2 are equipped with a phase change material sleeve 1, a phase change material 2 for summer, a phase change material 3 for winter, and a heat storage Thermal insulation filler 4, body of wall 5, rotating shaft 9, rotating gear 10, rotating chain 11.

[0043] In summer or winter, the rotating chain 11 needs to be adjusted at the same time to drive the rotating gear 10, the rotating shaft 9 and the phase change material sleeve 1 to rotate, so as to adjust the phase change material on the inner surface of the wall for latent heat storage and heat release.

Abstract

The invention discloses a phase-change-temperature-adjustable phase change material wall structure. The structure can be applied to the fields of civil building heating, air-conditioner energy conservation, green building energy conservation, passive building energy conservation and the like. Multiple phase change material sleeves arranged in an array are arranged on the surface, facing the room,of the wall, and each phase change material sleeve is filled with phase change materials used in summer and phase change materials used in winter. By means of a driving unit, the phase change materialsleeves are driven to rotate, then the positions of the phase change materials used in summer and the phase change materials used in winter in the wall are adjusted, and it is ensured that the phasechange materials on the surface layer in the wall can play the phase change latent heat storage and heat release capacity all the time in different seasons. The phase-change-temperature-adjustable phase change material wall structure has the advantages of being high in heat storage and release density, high in phase change rate, good in thermal performance, high in flexibility of operation and thelike.

Description

technical field [0001] The invention belongs to the field of civil buildings, and relates to a phase change material wall structure, in particular to a phase change material wall structure with adjustable phase change temperature, which can be applied to civil building heating and air conditioning energy saving, green building energy saving, passive building Energy saving and other fields. Background technique [0002] With the rapid increase of population and the improvement of indoor thermal comfort requirements, building energy consumption has grown rapidly, accounting for 40% of the world's total energy consumption, especially heating and cooling energy consumption in buildings has accounted for 68%. Therefore, scholars at home and abroad have developed different building energy-saving technologies to improve building energy utilization and reduce building indoor heating energy consumption. [0003] Phase change materials, due to their high heat storage density, are wid...
