Description
Technical Field
The invention relates to the technical field of buildings, in particular to an environment-friendly and energy-saving airflow channel structure.
Background
In order to deal with the severe cold and hot summer alternately generated in four seasons, modern buildings cause huge energy consumption in heating and refrigeration. However, a large amount of energy consumption does not create a comfortable environment that is warm in winter and cool in summer for human beings, and meanwhile, social development brings about problems of energy crisis, environmental pollution, climate deterioration and the like. Therefore, how to build the energy-saving building which is warm in winter and cool in summer has long-term significance. Traditional buildings have a very high harmony in the aspect of construction technologies warm in winter and cool in summer, and the civil engineering buildings are the model among them. The Fujian earth building is a huge residential building which is loaded by adopting rammed earth walls and wood beams. In summer, a huge eave and a trotting corridor are added on a rammed earth wall which is tall and thick in the earth building to shield the interior of the earth building, and street wind formed by a channel in the earth building creates a cool living environment in the building; in severe winter, the rammed earth wall resists cold wind invasion, vigorous people in the building and smoke of the kitchen stove at the bottom form warm and comfortable microclimate in the building. Meanwhile, the heavy rammed earth wall has an indoor humidity adjusting function, absorbs moisture in the air in plum rain seasons, does not have moisture regain or generate condensed water on the surface of the earth wall, and can naturally release moisture in dry autumn.
The earth building form cannot meet the living requirements of modern people, but the characteristics of being warm in winter and cool in summer are functions which are lacked and urgently required by modern buildings. Unfortunately, scientific research reports on earth buildings warm in winter and cool in summer are still relatively lacked, and most of the scientific research reports are still introduced in the science popularization of the earth buildings. The applied principle of the energy-saving peripheral structure designed in some documents and patent reports is similar to the way of adjusting the temperature by forming tunnel wind in the earth building. For example, korean lover et al designed an environment-friendly and energy-saving phase-change peripheral structure, in which an airflow channel is formed in a wall body to convey cold and hot air, so as to achieve an effect of regulating indoor temperature, and a phase-change material in the wall body also plays a role of regulating temperature (patent No. CN 206693433U). But the peripheral structure is more suitable for a small-scale building mode, such as a large building, and a house type which is not close to the peripheral wall of the building cannot enjoy a wall body with an airflow channel; on the other hand, the wall body is exposed to sunlight for a long time in summer, and the cooling effect can be greatly reduced.
