Embodiment Construction

[0047] The present invention is further illustrated below by way of examples.

[0048] The architectural design method of air age visualization can not only create thermal comfort and reduce the use of air conditioning, but also reduce the possibility of "building syndrome".

[0049] Air Age Formula for Numerical Calculation

[0050] The numerical calculation method is based on the mass conservation equation of the tracer gas to obtain its mass concentration transport equation, and then according to the tracer gas method, the transport equation of the air age can be deduced:

[0051]

[0052] In the formula, u, v, w are the velocities in the directions of the three coordinate axes of x, y, and x respectively; they are the diffusion coefficients. It can be seen from the above formula that the air age is related to the flow and diffusion coefficients. The equation form is the same as the continuity equation, momentum equation, and turbulence model equation. With the air ...

Abstract

The invention relates to a building design method with air age visualizing. Through the intelligent operation of computers, the distribution diagram of air ages at different heights can be obtained, and then the building design method with air age visualizing can be realized. The distribution of the air ages can be visually observed through the obtained air age distribution diagram. The method has the advantages that the visual and quantitative energy-saving analysis method is realized through natural ventilation, and an effective technical scheme is explored for the energy saving of a building; a natural ventilation system is selected, the building is considered as a living organic body and can exist harmoniously with climate, and then the building is applicable to the requirement of a building user; although the building design method with air age visualizing is not in the starting phase in China, along the increasing energy-saving requirement, the ecological and green concepts are deeply impressed into the mind of people, the recognition mind is converted from 'human first' to 'building first', and the building design method with air age visualizing is sure to spring up.

Description

technical field [0001] The invention relates to the application field of computer technology, in particular to a building design method for visualizing the air age, which can easily and accurately observe the air age index inside the building, so as to find out the control method for making it stable. Through these obtained air age distribution maps, the distribution can be observed intuitively, so as to conduct maximum investigation and research on air age. 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 the upper side vents. Background technique [0002] Today, as human health is increasingly valued, natural ventilation is particularly important for the relationship between human comfort and building energy efficiency. According to the definition of Sandberg et al., the air age is the time that the air at a certain point in the room has stayed in...
