Problems solved by technology

At the current stage where air conditioning is the main cooling measure, this greatly increases the energy consumption of air conditioning, which is not conducive to building energy conservation and sustainable development
In addition, the high temperature of the roof in summer also adversely affects the building, thereby shortening the life of the building
[0003] The heat gained in the room is directly proportional to the temperature difference between the outside of the roof and the room. If the temperature difference between the outside of the roof and the room is high, even if the insulation measures are improved, the heat gained in the room will still increase significantly, thereby increasing the cooling load.

Embodiment 1

[0037] An integrated roof panel, such as figure 1 As shown, it includes an upper panel 1, a waterproof layer 2, and an air circulation layer that are connected to each other from top to bottom; Screw connection; the upper panel 1 is selected from color steel plate, cement tile or glass fiber panel, etc., preferably a surface layer material with good thermal conductivity, such as color steel plate, which can promote the heat absorption of the phase change layer during the day, and the phase change layer at night The purpose of rapid heat dissipation; the waterproof layer 2 is a synthetic polymer waterproof membrane or a modified asphalt waterproof membrane.

[0038] During specific implementation, the air circulation layer includes the phase change layer 3, the ventilation layer 4 and the base layer connected in sequence, and the air circulation layer can strengthen the air circulation, so that the heat of the phase change layer 3 can be dissipated as soon as possible.

Embodiment 2

[0048] figure 2 It is a schematic cross-sectional diagram of the connection of two cooling integrated roof panels and their connection with the roof truss, as shown in figure 2 As shown, the joint of two integrated roof panels forms a concave-convex surface, which is connected to the light steel keel beam 10 through self-tapping screws 9, and can also be connected to the wooden beam 10; the gap between the two integrated panels Partially use foam glue and sealant 11 (such as building sealant, commercially available) to seal.

[0049] In the actual implementation process, the cooling integrated roof panel of the present invention can also be prefabricated in a factory.

Abstract

The invention relates to a cooling integral roof panel and a cooling integral roof comprising the same. The integral roof panel comprises an upper panel, a waterproof layer and an air circulating layer connected as a whole from top to bottom; the air circulating layer comprises a phase change layer, a ventilation layer and a base layer connected in sequence; and the base layer comprises a wallboard, a dampproof vapor separation layer and a bottom layer panel connected in sequence. The cooling integral roof panel uses the phase change layer of 40-48 DEG C for absorbing roof sunlight heat to reduce and delay the roof temperature in summer, and the temperature can be reduced by 10-15 DEG C to the greatest extent, so that the roof and indoor temperature difference is reduced, the indoor heat transfer is reduced, and the purposes of reduction of the air conditioner load, energy conservation and consumption reduction are achieved; and the cooling integral roof panel can be used as a roof insuch buildings as a framework concrete structure, a timber structure and a steel structure, and can be used as an additional cooling integral roof panel for a traditional building roof.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a cooling integrated roof panel and a cooling integrated roof including the same. Background technique [0002] The climate in southern my country is warm. In summer, due to sunlight, the roof gets heat through the sun. The temperature generally exceeds 60°C, or even exceeds 70°C. The reason is that the cooling load in the room is greatly increased. At the current stage where air conditioning is the main cooling measure, this greatly increases the energy consumption of air conditioning, which is not conducive to building energy conservation and sustainable development. In addition, the high temperature of the roof in summer also adversely affects the building, thereby shortening the life of the building. [0003] The heat gained in the room is directly proportional to the temperature difference between the outside of the roof and the room. If the temperature difference between ...
