Description

Technical Field

[0001] The present invention relates to an external wall heat insulation and preservation device applicable to an intermittent air-conditioning and heating mode, belonging to the fields of energy-saving buildings and green buildings. Background Art

[0002] With the development of energy-saving buildings and green buildings, the demand for external wall heat insulation and preservation is very common. However, most building external walls adopt the practice of external wall insulation. This practice mainly relies on heat-insulating materials with low thermal conductivity to prevent heat from escaping indoors in winter and reduce the amount of solar radiation heat entering indoors in summer. In northern regions, the energy-saving demand for building external walls is mainly for winter insulation, and continuous heating is provided in winter. This external wall insulation practice is reasonable. In southern regions, the energy-saving demand for building external walls is mainly for summer heat prevention. Heat-insulating materials with low thermal conductivity can reduce the amount of solar radiation heat accumulated on the wall and entering indoors during the day, which is beneficial to energy conservation; but at night, they will also prevent the heat that entered indoors during the day from dissipating outdoors, which is not conducive to energy conservation. Therefore, for residential buildings where people go out early and return late, due to the intermittent air-conditioning and heating mode that pauses during the day and is used at night, the air-conditioning energy consumption in summer will increase significantly.

[0003] In addition, the common external wall external insulation structure is integrally arranged on the outside of the wall. The insulation device directly faces the test of the external environment. Coupled with the difficulty in ensuring the construction quality, common quality problems such as cracking often occur, and in severe cases, quality safety accidents such as the shedding of the insulation layer may even occur. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an external wall heat insulation and preservation device applicable to an intermittent air-conditioning and heating mode, separating heat preservation and heat insulation: continuing the idea of material heat preservation and setting the heat preservation layer on the indoor side of the external wall; changing to the method of structural heat insulation, setting the sunshade on the outdoor side of the external wall to cut off the path of summer solar radiation reaching the external wall, reducing the amount of solar radiation heat received by the external wall during the day, and not affecting the heat dissipation of the wall at night, thereby reducing the air-conditioning energy consumption in summer.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: an external wall heat insulation and preservation device applicable to an intermittent air-conditioning and heating mode, the device includes an external sunshade, a solid external wall, and an internal heat preservation layer. The external sunshade is located on the outdoor side of the solid external wall and is fixed on the solid external wall through metal anchor fittings; the internal heat preservation layer is located on the indoor side of the solid external wall and is attached to the solid external wall.

[0006] As a further preference of this solution, the material of the external sunshade is any one of aluminum alloy plates, stainless steel plates, galvanized steel plates, and enamel steel plates.

[0007] As a further preference of this solution, the external sunshade is composed of a panel and right-angled flanges and 180° flanges around it.

[0008] As a further preference of this solution, convection heat dissipation holes are drilled on the panel.

[0009] As a further preference of this solution, installation holes are drilled on the 180° flange.

[0010] As a further preference of this solution, convection heat dissipation holes (1.4) are opened at the position where the installation hole (1.5) faces the panel (1.1). The metal anchor passes through the installation hole of the 180° flange, presses the 180° flange against the solid exterior wall surface, and the other end drills into and is fixed on the solid exterior wall.

[0011] As a further preference of this solution, the metal anchor is made of stainless steel or galvanized steel.

[0012] As a further preference of this solution, the internal thermal insulation layer is fixed on the solid exterior wall by bonding or anchoring.

[0013] As a further preference of this solution, a waterproof mortar layer is provided between the external sunshade and the solid wall.

[0014] As a further preference of this solution, the internal thermal insulation layer is made of any one of organic thermal insulation boards, inorganic thermal insulation boards, thermal insulation pastes, and composite thermal insulation materials.

[0015] Compared with the existing external wall heat insulation and thermal insulation devices, the present invention has the following characteristics and beneficial effects:

[0016] (1) It does not affect winter thermal insulation

[0017] Buildings in some southern regions need to carry out winter thermal insulation. For the intermittent heating mode that is suspended during the day and used at night, the actual heating energy consumption is much lower than that of continuously heated buildings in the northern regions. Installing a thermal insulation layer on the inner side of the external wall can meet the building energy-saving requirements of southern regions with intermittent heating.

[0018] (2) It has better heat prevention effect in summer

[0019] The building energy-saving requirements in southern regions mostly focus on heat prevention in summer. The present invention is used for structural heat insulation during the day in summer and does not affect the night-time heat dissipation of the building, especially suitable for the intermittent air-conditioning and heating modes that are suspended during the day and used at night.

[0020] (3) It is convenient to install

[0021] According to the position of the external sunshade, the electric drill can directly pass through the convection heat dissipation holes and the installation holes to drill holes and install metal anchors on the wall surface. There is no need to drill holes and install strictly according to the previous positioning, nor is it necessary to pre-install the keel, which greatly simplifies the installation of the external sunshade. Since the external wall insulation is set on the indoor side, there is no high-altitude operation, and the construction quality is easy to control. Description of the Drawings

[0025] The markings in the figure are: 1 - external sunshade; 1.1 - panel; 1.2 - right-angled folding edge; 1.3 - 180° folding edge; 1.4 - convection heat dissipation hole; 1.5 - installation hole; 2 - solid wall; 3 - internal insulation layer; 4 - metal anchor; 5 - waterproof mortar layer. Detailed Description of the Invention

[0026] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0027] As Figure 1 shown, an external wall heat insulation and preservation device suitable for the intermittent air-conditioning heating mode is characterized in that the device includes an external sunshade 1, a solid external wall 2, and an internal insulation layer 3. The external sunshade 1 is located on the outdoor side of the solid external wall 2 and is fixed on the solid external wall 2 through a metal anchor (4); the internal insulation layer 3 is located on the indoor side of the solid external wall 2 and is attached to the solid external wall 2.

[0028] In this embodiment, the external sunshade 1 is composed of a panel 1.1 and right-angled folding edges 1.2 and 180° folding edges 1.3 around it; convection heat dissipation holes 1.4 are drilled in the panel 1.1. Convection heat dissipation holes (1.4) are opened at positions of the installation holes (1.5) facing the panel (1.1). The metal anchor 4 passes through the installation hole 1.5 of the 180° folding edge 1.3, presses the 180° folding edge 1.3 on the wall surface of the solid external wall 2, and the other end drills into and is fixed on the solid external wall 2

[0029] In this embodiment, a waterproof mortar layer 5 is provided between the external sunshade 1 and the solid wall 2.

[0030] Working principle of this device:

[0031] (1) Winter heat preservation

[0032] For buildings adopting the intermittent heating mode in winter, their actual energy consumption is much lower than that of continuously heated buildings. Therefore, the thickness of the external wall insulation layer of intermittently heated buildings can be appropriately reduced.

[0033] (2) Summer heat insulation

[0034] The perforated sunshade is arranged on the outdoor side of the external wall, so that most of the summer solar radiation during the day directly shines on the sunshade; after the sunshade absorbs the solar radiation energy, its temperature rises, and a part of the absorbed heat is dissipated into the surrounding air by convection, and another part of the heat is directly dissipated outward by long-wave radiation. In this way, most of the direct solar radiation energy is intercepted, absorbed and dissipated into the surrounding environment by the perforated sunshade, avoiding the direct absorption of solar radiation by the external wall of the building, thereby reducing the solar radiation energy entering the room through the external wall and achieving the effect of sunshade and heat insulation. This heat insulation structure reduces the air-conditioning energy consumption during the day in summer. For residential buildings where people go out early and return late, even if the air conditioner is only used at night, the perforated sunshade also reduces the accumulation of solar radiation energy in the room during the day, and also reduces the air-conditioning energy consumption at night in summer.

[0035] In addition, since the thickness of the external wall insulation layer is appropriately reduced, it is convenient for the heat in the room to be dissipated to the outside, which is more conducive to reducing the air-conditioning energy consumption at night in summer.

[0036] (3) Drilling holes in the external sunshade

[0037] Drilling holes in the external sunshade can greatly improve the convective heat dissipation efficiency of the sunshade in summer; the drilling rate can also be adjusted according to needs to meet different requirements for the shielding rate of direct solar radiation. In addition, after the sunshade is drilled, the inside and outside are connected, which can reduce the influence of wind load.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those of ordinary skill in the art should understand that the above embodiments do not limit the protection scope of the present invention in any form. Any technical solutions obtained by means of equivalent replacement and the like fall within the protection scope of the present invention. The parts not involved in the present invention are the same as or can be implemented by the prior art.
