Description

Energy-saving and environment-friendly large-scale public building atrium partition hot-pressing ventilation structure

Technical Field

The invention relates to the field of energy conservation and environmental protection, in particular to an energy-saving and environment-friendly large-scale public building atrium partition hot-pressing ventilation structure.

Background

Natural ventilation is a basic requirement of green buildings and healthy buildings, and especially during epidemic situations, the natural ventilation is more important as one of effective measures for building emergency. The natural ventilation is a ventilation and gas transmission mode for indoor areas and the like by utilizing natural wind pressure, air temperature difference, air density difference and the like, and does not depend on an air conditioner completely. With the rapid development of urbanization, large public buildings gradually become very common building types, but the large public buildings often have the characteristics of large space scale, relatively closed form and complex peripheral functions, and are more and more prone to depend on high-energy-consumption equipment driving and air-conditioning regulation, so that the large public buildings are challenged by high energy consumption and low comfort in actual operation. Most public building energy consumption is concentrated on 50-70Wh/(m2a), and the energy consumption of public building space with larger scale and complicated functional organization is concentrated on the higher energy consumption level of 120-150Wh/(m2 a). Besides high energy consumption, the health problems brought by the enclosed space of the large public building are also serious. According to the statistics of the World Health Organization (WHO), 30% of newly built buildings and nearly 30% of renovated buildings affected by the Sick Building Syndrome (SBS) in the world currently suffer from about 20% -30% of office staff. Strengthening natural ventilation from 'airtight buildings' to 'climatic buildings' is a new challenge in the field of building design, especially for large public buildings.

With the expansion of the building scale, the natural ventilation technology has limitations, and the single wind pressure ventilation is difficult to play an effective performance in a large public building space. Experiments show that the building ventilation path is lengthened due to the fact that the depth exceeds 40 m, and the wind pressure ventilation effect is limited. The hot-pressing ventilation depends on the indoor and outdoor temperature difference and the height of an airflow channel or the vertical distance between a ventilation upper opening and a ventilation lower opening, is particularly important for solving the ventilation problem in a large-scale space, and can be realized by using an atrium space, a building transition space or a building double-layer interface space in a building.

The existing ventilation modes of more buildings, particularly large public buildings have the defects.
