Natural Ventilation Performance of a Residential Single House in Thailand

Abstract

In this thesis presents the study of natural ventilation performance for planning design of single residential house in Bangkok Method includes simulation by computational fluid dynamics program (CFD) on 4 different cases: 1) daytime without wind 2) daytime with 3m/s wind velocity 3) daytime with 3m/s wind velocity (closed transom windows) and 4) nighttime with 3m/s wind velocity The CFD model validation done by compared the values with the obtained data from the wind tunnel experiments However some discrepancies are present near the floor and ceiling areas due to the material a good agreement between experiment and CFD results was found It is discovered that outdoor wind velocity did not have considerable effect on the indoor air quality factor but significant effect on the level of comfort However the finding highlighted that better performance could be observed near the opening It is also found that PMV and PPD values slightly higher that the suggested acceptability in ASHARE standards
