Problems solved by technology

If the heat transfer coefficient is designed too large, although the heat conducted from the indoor air to the outside through the wall at night is increased, the heat conducted to the room through the wall during the day is also increased.
Therefore, the wall with a fixed heat transfer coefficie...

Abstract

The invention provides a wall allowing a heat transfer coefficient to be automatically adjusted. The wall comprises a surface layer, a variable heat resistance layer and a load bearing layer. The variable heat resistance layer is arranged between the surface layer and the load bearing layer and comprises double metal sheets. In a cold state, the double metal sheets directly or indirectly make contact with the surface layer and the load bearing layer to build a conduction heat bridge between the surface layer and the load bearing layer, and the heat transfer coefficient of the wall is increased. In a hot state, the double metal sheets bend, deform and separate from the surface layer and/or the load bearing layer, so that the conduction heat bridge between the surface layer and the load bearing layer is broken, and the heat transfer coefficient of the wall is decreased. Through the wall allowing the heat transfer coefficient to be automatically adjusted, the quantity of heat conducted from outdoor space into indoor space in daytime can be reduced, an outdoor cold source can also be sufficiently used for cooling indoor air at night, and air-conditioning energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection walls, in particular to a wall with automatic adjustment of heat transfer coefficient. Background technique [0002] The exterior wall of the building is the interface between the interior space and the exterior space of the building. The heat exchange between the interior space of the building and the exterior space is realized through the intermediary of the wall. Therefore, the heat transfer coefficient of the wall has a great influence on the building energy consumption. The greater the heat transfer coefficient, the more heat is conducted through the wall. The lower the heat transfer coefficient, the less heat is conducted through the wall. In summer, when the outdoor temperature is too high during the day, in order to reduce the energy consumption of the air conditioner, the heat transferred into the room through the wall should be reduced, so the smaller the heat transfe...
