A method for improving the natural lighting and ventilation of the basement, in daytime, solar radiation penetrates through a transparent glass cover plate 3 to enter a cavity 1 and then is absorbed by a heat collecting plate 2, air at the upper part in the cavity 1 is heated, so that the air generates an internal and external density difference, the air in the cavity 1 is driven to flow upwards continuously, the heated air is low in density and then is exhausted outdoors from an air outlet at the upper part of the cavity 1, the air which is cold indoors and slightly high in density enters a ventilation duct 8 through a grille type ventilation opening 9 and is sucked into the cavity 1 through the ventilation opening 6, and the circulation of the indoor air is promoted.
The invention has the beneficial effects that:
the invention realizes the requirements of natural lighting and ventilation of the basement without using mechanical equipment, and effectively improves the indoor hot and humid environment. The invention is not only beneficial to saving ventilation and illumination energy consumption, but also creates a healthier and more comfortable environment for the basement, and accords with the development trend of the current green buildings and healthy buildings.
Drawings
Fig. 1 is a schematic view of an application scene of the basement natural lighting and ventilation method provided by the invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, a method for improving natural lighting and ventilation of a basement includes a cavity 1 formed between an outer wall of the basement and soil, a heat collector 2, a glass cover plate 3, a light reflection plate 5 and an elevated wood floor 7. The cavity 1 extends to about 1.5m above the ground, the extended part of the side surface and the top of the cavity are enclosed by a glass cover plate 3, and the top of the cavity 1 is provided with an air outlet 4 communicated with the outside. The heat collector 2 is arranged on the underground outdoor wall at the top of the cavity 1. The basement ground adopts built on stilts timber apron 7, 7 installation grid formula vent 9 on the built on stilts timber apron. The grille type ventilation opening 9 is connected with the ventilation duct 8 below the raised wood floor 7. The ventilation channel 8 is connected with the ventilation openings 6 on the outer wall and the inner wall of the basement.
And the reflector 5 is arranged near the upper part of the outer window of the basement and on one side of the cavity 1, which is contacted with the soil, and the specific position is determined according to the change of the sunlight angle in the local day.
The grid type ventilation opening 9 is arranged at the indoor position far away from the air inlet, so that the indoor short circuit of air flow is avoided.
The structure of the present invention is further explained below with reference to the working principle.
Referring to fig. 1, in daytime, solar radiation enters a cavity 1 through a transparent glass cover plate 3 and then is absorbed by a heat collecting plate 2, air at the upper part of the cavity 1 is heated, so that the air has an internal and external density difference, the air in the cavity 1 is driven to flow upwards continuously, the heated air has a lower density and is discharged outdoors from an air outlet at the upper part of the cavity 1, the air which is relatively cool indoors and has a slightly higher density enters a ventilation channel 8 through a grille type ventilation opening 9 and is sucked into the cavity 1 through a ventilation opening 6, the circulation of the indoor air is promoted, the hot and humid environment of a basement is improved, and the occurrence of the ground moisture regain phenomenon is.
