Description
Technical Field
The invention relates to the technical field of sealing systems of buildings, in particular to a sealing system for a passive ultralow-energy-consumption building.
Background
The market status: at present, most areas in the north of China begin to be newly built or reformed with passive buildings, which completely take the way of German passive house technology;
in China, energy conservation of buildings is advocated in hot summer and cold winter areas, but the popularization of passive buildings is just started.
In order to improve comfort, passive buildings in the market currently adopt systems of "three constant" (constant temperature, constant humidity, constant oxygen) and "five constant" (constant temperature, constant humidity, constant pressure, constant oxygen, constant static), but these systems all realize intelligent effects for the concepts of "three constant" and "five constant" through corresponding equipment and sensors.
As is known, the sealing performance of a common building is not ideal, fine gaps exist at joints of windows and joints of pipelines, the gaps enable the building to be in a state of communicating with the external environment, and on a roof and the ground, although no gap exists, the building and the external environment can exchange heat due to no effective measures, which also causes waste.
To this end, we propose a sealing system for passive ultra low energy buildings.
