Description
Technical Field
The invention relates to the technical field of construction, in particular to an environment-friendly energy-saving airflow channel structure.
Background
In order to cope with the cold and hot weather alternately produced in four seasons, the modern buildings cause huge energy consumption in heating and refrigerating. However, a great amount of energy consumption does not create a comfortable environment for people to warm in winter and cool in summer, and at the same time, 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 meaning. The traditional building has high building precision in the aspect of building technology which is warm in winter and cool in summer, and the good fortune is a model in the building. The Fujian earth building is a huge residential building which adopts rammed earth walls and wooden beams to bear load. In summer, the soil building is high and thick, a large eave and a horse gallery are added to provide shielding for the interior of the soil building, and roadway wind formed by the interior channels of the soil building creates a cool living environment in the building; the rammed earth wall resists cold air invasion in severe winter, and the vigorous atmosphere in the building and the flue gas of the kitchen stove at the bottom layer form warm and comfortable microclimate in the building. Meanwhile, the thick rammed earth wall has an indoor humidity adjusting function, moisture in the air is absorbed in a plum rain season, the surface of the earth wall cannot get damp again or generate condensation water, and the moisture can be naturally released in a dry autumn.
The building form of the earth building can not meet the living demands of modern people, but the characteristic of being warm in winter and cool in summer is a function which is lack of urgent demands of the modern building. Unfortunately, scientific research reports about the warmth in winter and cool in summer of the building are still relatively lacking, and most of the reports still remain in the scientific introduction of the building. The applied principle of the energy-saving peripheral structure designed in some documents and patent reports is similar to the mode of forming roadway sub-wind in a building to regulate the temperature. For example, han Aigong et al have devised an environment-friendly energy-saving phase-change peripheral structure, in which an air flow channel is provided in a wall body to enable cold and hot air to be delivered, thereby achieving the effect of adjusting indoor temperature, and the phase-change material in the wall body also has the effect of adjusting temperature (patent number CN 206693433U). However, the peripheral structure is suitable for small-scale building modes, such as large-scale buildings, and a house type building which is not close to the outer wall of the building cannot enjoy the wall body with the 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.

In the daytime in winter, the open environment air inlet 1, the cold air inlet 7, the cold air outlet 13 and the negative pressure air feeder 14 are closed, the hot air channels are started, one of the two opposite shutters 18 is closed, the air in the open environment enters the air heating room 16, the solar roof heat collector 17 heats the air, the building roof positive pressure air feeder 15 is started, the positive pressure air feeder 15 sends the hot air into the floor trapezoid air channel 9, the ceiling trapezoid air channel 11 and the single-side wall trapezoid air channel 10, the hot air exchanges heat with the room through the floor, the ceiling and the wall, the heat is transferred into the room, a warmer and comfortable indoor environment is created, meanwhile, the heat-preservation phase-change material layer 20 stores energy, and the air after heat exchange is discharged from the hot air port 8 of the first floor into the open environment; at night, the cold air channel and the hot air channel are closed at the same time, so that the air flow channel forms a closed space, and the heat-preserving phase-change material layer 20 releases heat stored in the daytime along with the gradual reduction of the temperature in the channel, thereby heating and preserving the heat of the room.
The practice of the invention is described above with reference to the accompanying drawings, but the invention is not limited to the specific embodiments described above, which are intended to be illustrative rather than limiting, and it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention, and are intended to be included within the scope of the appended claims and description.
