The phase change material can be selected from gas-liquid phase change material, and the building structure wall can adopt a general reinforced concrete structure. The normal temperature gas-liquid phase change material needs to be selected from nontoxic and harmless materials with high latent heat of normal temperature boiling point, good heat transfer surface and higher heat transfer coefficient.
The building energy-saving constant temperature system based on the phase-change energy storage material provided by the embodiment stores the phase-change material in the phase-change heat storage device 5; the building wall comprises a structural wall body 3, and an outdoor heat exchange layer 2 and an indoor heat exchange layer 4 which are arranged on two sides of the structural wall body 3; is connected with the outdoor heat exchange layer 2 and the phase change heat storage device 5 through a first circulating pipeline 21; is connected to the indoor heat exchange layer 4 and the phase change heat storage device 5 through a second circulation pipe 41. The indoor heat is absorbed by the indoor heat exchange layer 4 in the daytime in the summer, the phase change material in the second circulation line 41 is gasified and stored in the phase change heat storage device 5, and the stored heat is liquefied by the medium and put into the outdoor environment until the night time when the phase change material circulates through the first circulation line 21. In winter, outdoor heat is absorbed by the outdoor heat exchange layer 2 in daytime, the phase change material in the first circulation pipeline 21 is gasified and stored in the phase change heat storage device 5, and the stored heat is circulated at night through the second circulation pipeline 41 and is liquefied by a medium and put into an indoor environment. By adopting the scheme, not only can the better heat preservation and insulation effect be achieved, but also the load of the indoor air conditioner can be effectively reduced by utilizing the heat storage and release of the phase change material, and the energy consumption of building operation can be reduced in a passive mode. Meanwhile, the scheme has little energy consumption and is arranged inside the building structure, so that the reliability is high, and the energy-saving constant temperature effect of the building can be ensured for a long time.

The outer decorative surface 1 is made of stone, face brick or real stone paint.

The inside and outside of the normal temperature solid-liquid phase change material layer 31 need to be sealed by the outdoor heat exchange layer 2 and the structural wall body 3 so as to avoid the loss of normal temperature solid-liquid phase change material and the reduction of heat storage performance. The normal temperature solid-liquid phase material layer 31 is arranged between the outdoor heat exchange layer 2 and the structural wall body 3, which is beneficial to ensuring the reduction of indoor temperature fluctuation of the building and does not influence the heat exchange between the outdoor heat exchange layer and the external environment. The solid-liquid phase material at normal temperature needs to be selected from materials with high latent heat of melting point between 20 ℃ and 26 ℃ and good heat transfer surface and higher heat transfer coefficient, and has better compatibility with the matrix material of the heat storage layer,

Further, the bonding layer comprises a bonding mortar layer and a grid cloth.
The normal temperature solid-liquid phase change material layer 31 in the above proposal absorbs the heat conducted in by the external facing 1 in a high temperature environment, the phase change material becomes liquid and is absorbed by the high specific surface area material with rich gaps, and the heat conduction to the internal structural wall is reduced; in a low-temperature environment, the normal-temperature solid-liquid phase material becomes solid to emit heat and is conducted to the structural wall body and the outer decorative surface 1. The heat absorption and release of the normal-temperature solid-liquid phase change material layer 31 can ensure that the temperature change range of the wall body of the building structure is smaller, and further avoid the occurrence of the condition of large indoor cold and hot load change.
