[0037] Ventilation holes 18 connected to the room are provided on the upper and lower sides of the Trombe wall. The size of the vent 18 is 500×400 mm, and the distance between the upper and lower vents 18 is 6500 mm. An electric valve is installed on the vent 18, which is opened from 8:00 to 18:00 and closed from 18:00 to 8:00.

[0038] The construction method of the utility model is as follows:

[0039] Step 1: Apply the base plate;

[0040] Step 2: construct the sun-facing exterior wall 1, the side wall 3 and the sun-facing exterior wall 2. The construction methods of the sun-facing exterior wall 1 and the sun-facing exterior wall 2 are the same, as follows:

[0041] like Figure 2 As shown, the building is built with a 300mm thick light aggregate inner insulation layer 9, a 185mm thick rock wool outer insulation layer is made on the sunny side outer wall 1, and a 265mm thick rock wool outer insulation layer is made on the back side outer wall 2. Cement mortar is used for leveling on the outside of the outer insulation. The outer wall surface is painted with a 1:3 cement mortar base, and then a 1:2.5 cement mortar is used to paint the surface layer. The thickness of the paint layer is ≥10mm to improve the self-waterproof ability of the wall. The outer wall tiles are matched according to the design requirements according to specifications, varieties, colors and proportions, and are pasted with 1:1 cement mortar or special pasting mortar. The brick joints are generally 8-10mm, preferably 9mm.

[0042] Step 3: The construction of the Trombe wall is carried out simultaneously with the construction of the building structure. The location of the Trombe wall is determined during the building design process, and the Trombe wall is constructed together with the building structure. The side wall 16 of the Trombe wall is structurally connected to the building exterior wall, the front side is inclined, and is covered with a 6mm thick glass cover plate 19;

[0043] Step 4: Construction of top plate 4

[0044] like Figure 3 As shown, after the construction of the 120mm thick structural layer concrete roof panel 10 is completed, insulation and waterproofing treatment are carried out. A 30mm thick light aggregate concrete layer 11 is superimposed with a 135mm thick extruded polystyrene board layer 12 as roof insulation, a 120mm thick cement mortar leveling layer 13 is made on the insulation layer, and finally a 40mm thick C20 fine stone concrete protective layer 14 is made on the top layer.

[0045] The working principle of the utility model is as follows:

[0046] A layer of glass is covered on the south-facing exterior wall except for the windows, leaving an air layer of 1000 mm in the middle, the outer surface of the light aggregate self-insulating block layer 17 is painted black or provided with heat collecting materials, and 500×400 mm ventilation holes are left at the top and bottom. Due to the characteristics of glass, infrared rays are not easy to penetrate glass, but have strong heating capacity; therefore, heat is locked in the cavity between the glass cover plate and the light aggregate self-insulating block layer 17, which can effectively heat the light aggregate self-insulating block layer 17 and the air.

[0047] In winter, the upper and lower vents of the lightweight aggregate self-insulating block layer 17 are opened during the day to absorb the radiant heat from the sun and heat the air in the interlayer by convection. Under the influence of thermal pressure, the air in the interlayer rises and flows into the room through the upper vents on the wall to provide heat for the room. At the same time, the low-temperature air in the room flows out of the room from the lower vents, thus forming a heat cycle. At night, the upper and lower vents are closed to allow the heat energy stored in the lightweight aggregate self-insulating block layer 17 to enter the room, making the room warmer.

[0048] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", and "fix" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The content of the utility model is not limited to the examples listed, and any equivalent changes made to the technical solution of the utility model by ordinary technicians in this field after reading the specification of the utility model are covered by the claims of the utility model.
