Green, environment-friendly and energy-saving passive ventilation method suitable for large public building

Abstract

The invention discloses a green, environment-friendly and energy-saving passive ventilation method suitable for a large building, which comprises the following steps of: (a) establishing a physical model: simulating indoor and outdoor wind environments of the large building in software, and in order to reduce the number of grids under the condition of not influencing a result, neglecting fine parts of the building during modeling, enabling the atrium space to be located in the middle, enabling the functional areas to be arranged around, and for the external environment, keeping the size of anexternal flow field area being 6-8 times that of a building; (b) setting boundary conditions; (c) establishing a mathematical model: carrying out discrete solution by adopting a reforming normalized group (RNG) k-Epsilon epsilon model; (d) researching the characteristics of the outer wall shutter; and (e) carrying out data simulation analysis: through comparison experiment data of multiple openingcombination schemes, taking the upper part of the atrium space as an exhaust port, taking a windward door as an air inlet, and promoting effective ventilation of each area of the whole building by matching with air exchange ports in multiple directions.

Description

technical field [0001] The invention relates to the field of passive ventilation of large public buildings, in particular to an environmentally friendly and energy-saving passive ventilation method suitable for large public buildings. Background technique [0002] Since modernization, large-scale public buildings have been vigorously developed and rapidly popularized. Various large-scale public buildings such as museums, science and technology museums, and exhibition halls have been continuously completed in various regions of China. Large-scale public buildings have become increasingly important and important in the field of construction. Emerging fields with prominent roles. [0003] All kinds of large-scale public buildings mentioned above have two common characteristics of spatial organization and indoor climate organization. On the one hand, in order to realize the publicity of the building, there is often a kind of atrium space with a height of up and down, which is n...

AI Technical Summary

Problems solved by technology

Existing large-scale public buildings mostly use various mechanical equipment to control the indoor climate, forming a closed building space, lacking connection with the external environment, and unable to effectively use the natural environment, resulting in huge building energy consumption

[0004] The traditional method of using mechanical equipment to regulate the climate consumes a lot of energy, which is contrary to the current sustainable and green building development trend. The large-scale public building design method combined with the building environment performance is relatively lacking in China. Therefore, the present invention focuses on the current large-scale public buildings. How to coordinate and complement each other in the two generalities, and integrate the large-scale atrium space into the dynamic ventilation method of large public buildings to optimize environmental performance
