Example Embodiment

[0047] The following examples further illustrate the present invention.

[0048] A visualized architectural design method of air velocity can not only create thermal comfort and reduce the use of air conditioning, but also reduce the possibility of "building syndrome". Using the architectural design method of air velocity visualization, the design of upper-rotation windows of facade doors and windows, and indoor vertical ventilation shafts provide good natural ventilation for Wenyuan Building and reduce the energy consumption of air conditioning.

Abstract

The invention relates to a visual air speed building design method. Airflow is observed by a visual air speed method, so that benefits can be certainly created for human health. The method aims to control the quality of indoor air to greatly help and support the human health, and to solve thermal comfort problems in summer or transition seasons and reduce the energy consumption by replacing or partially replacing air conditioners. According to the visual air speed building design method, an effective technical scheme is explored for the energy saving of buildings; the visual air speed building design method can be used for optimizing designs in the future to prevent humans from being bothered by air conditioning diseases, create benefits to human health and benefit all human beings.

Description

technical field [0001] The invention relates to the application field of computer technology, and describes a building design method for air speed visualization, which can easily and accurately observe the air speed vector distribution inside the building, so as to find out the control method for making it stable. This simulation takes the ground floor of Wenyuan Building as an example. The middle part is a corridor, and the two sides are symmetrical classrooms. Exhaust upwards through upper side vents. Background technique [0002] The current research on natural ventilation focuses on the design of natural ventilation using traditional experience, most of which are qualitative designs, lacking quantitative analysis results in terms of energy saving. At present, there are two methods of quantitative analysis, wind tunnel test and computational flow dynamics (CFD). With the development of computer technology, CFD has been widely used in a cheap and convenient way. A buildi...
