| Summary: | 碩士 === 國立成功大學 === 建築研究所 === 83 === This study focuses on the investigation of the airflow patterns
, affecting the indoor air quality, of a bedroom in Taiwan.
Through numerical simulation, we will obtain airflow patterns.
From the airflow patterns, we could conclude the optimum
designs for the effective areas, the height and location for
windows. results will enable us to effectively control the
inflows, indoor air quality to ensure a comfortable and healthy
■Objectives: (1).Understand the airflow patterns of natural
ventilation in indoor spaces through CFD simulation.
(2).Investigate the impacts of the unit bedroom space scale,
area of opening, transom positions upon indoor air (3).Study
the influences of the outdoor wind velocity and the bedroom
space scale upon indoor air environment, functioning as a
handy reference for unit indoor design.■Methodology: (1).Based
on literatures, to conduct comparative analysis on models,
space scale and mold distance scale to choose an unit space
functions and scale range. (2).To probe into the turbulent flow
model and grill systems'' bility through literature and the
comparison with wind experimental data. (3).Analyze the indoor
air environments through airflow velocity and their impacts
upon velocity field to probe into the air exchange volume, the
air exchange frequency and impacts upon the indoor ventilation
and the air exchange■Results: (1).A single air outlet/inlet
tends to produce a stagnant indoor (2).Prolonged the inlet
length will bring down the velocity of breathing zone. (3).The
smaller the outdoor wind velocity, the lower the air frequency
and the larger the area of windows. (4).Under natural
ventilation, higher transom position makes air exchange
performance than lower transom position.
