Description

A kind of green house and its design method which strengthens drafting and ventilation by hot-pressing wind pressure

technical field

The invention relates to the technical field of construction engineering, in particular, to a green house and a design method thereof for enhancing draft ventilation through hot-pressed wind pressure.

Background technique

Natural ventilation is a sustainable technology, and countries are developing different ventilation methods of various building construction methods in combination with regional climate characteristics to strengthen the application of natural ventilation in buildings. For example, the Osaka Gymnasium uses air ducts and induced natural ventilation devices to ensure natural ventilation and cooling, while underground air ducts reduce the fresh air load of the air conditioning system. The headquarters building of Frankfurt Commerzbank uses atriums and patios to adjust the internal climate of the building. In winter, the skylights in the atrium are closed to form passive solar installations. In summer, the skylights are opened for ventilation. , roof insulation, tall exterior walls and other architectural designs to achieve natural ventilation by suppressing wind pressure during the day, and promoting natural ventilation and cooling by hot pressure at night. In my country, various natural ventilation designs have emerged in recent years. For example, in the underground shopping mall in front of Yueyang Railway Station, the large negative pressure wind shadow area formed by the tall railway station house on the back is used to form an effective pressure difference between the north and south exits. , making the underground shopping mall form a natural ventilation airflow from south to north throughout the year, meeting people's hygienic requirements for fresh air. The Guangzhou Mobile Communication Hub Building takes into account the needs of ecological energy saving in terms of building shape, building structure and building materials, and makes full use of the thermal buffering, ventilation and lighting effects of the atrium; the civil buildings in the northeast area are designed with ducted natural ventilation, and each room in each room is designed with natural ventilation. There is generally an outdoor air inlet on one outer wall, and an indoor air outlet under the ceiling. The exhaust duct is connected to the horizontal main pipe of the top attic, and then discharged to the outdoors through a vertical duct with a hood on the top. The average ventilation power can meet people's requirements for fresh air. However, the above designs all need to combine regional characteristics and make use of local natural winds. In the southern part of my country, the summer is hot and humid, and the wind is weak, and the poor indoor ventilation will seriously affect the physical health and thermal comfort of the human body, causing physical and psychological discomfort. Therefore, those skilled in the art urgently need to design a new type of house that can solve the above problems.

In this way, the ventilation windows 130 facing the south side can be guaranteed to receive the outdoor wind from the south side, and the north-south direction is realized. Ventilation, adapt to the wind direction of the summer wind. In addition, the ventilation windows 130 facing the east side can also receive the outdoor wind from the east side, so that the green house can also adapt to the wind directions of different regions.

In addition, in the indoor building area 110 of the green house, the north side space is usually planned as a bedroom area, and the south side space is planned as areas such as kitchen, living room, dining room, etc. Therefore, the north side roof 140 of the bedroom area is usually double-layered. The thermal structure increases the thermal insulation performance of the bedroom area. In addition, a skylight for ventilation (as shown by reference numeral 10 in FIG. 2 ) is arranged in the middle of the double-layer thermal insulation structure to enhance the ventilation performance of the bedroom area. The roof 150 on the south side of the kitchen, living room, dining room and other areas adopts a sloping structure with a high north and a low south, which is in the same direction as the wind pressure and airflow when the ventilation windows are opened, which facilitates indoor air circulation and guides the rainwater from the roof to discharge, while the north is high in the south. The low structure also creates enough shading space to prevent excessive solar radiation from entering the interior.

A solar chimney is also provided on the top of the roof 150 on the south side, and the vertical hot chimney is used to extract the wind, and the indoor vertical draft is increased by using the hot chimney effect.
