| Summary: | 碩士 === 國立臺灣科技大學 === 建築系 === 95 === It takes lots of times that people occupied the building; therefore, the interior environment of a building has a tremendous impact on people. In the interior environment, the temperature and air quality are the most important elements. To adopt the economic, and rational ventilation tactics, one must take the cooling and heat load in the room away to improve and maintain the good environment in the room. The purpose of this research is to utilize Computational Fluid Dynamics to analyze the heat environment in the room of summer、spring、autumn, and put
forward the design principle and method.
The result showed the state of natural ventilation, compare to the section of a flat roof without skylight, the section of a high flat roof and the section forms with high oblique roof had obvious results for driving the indoor air flows and reduces the indoor temperature. The air conditioner setting in outlet position of summer，the best position is to opposite the inlet, and it can make a room circulation and take
much heat away.
After putting up 30% of the radiant cooling ceiling with 21℃ of surface temperature, it can reduce 20% of the air supply velocity with the same indoor average temperature. If only confer with the 2m high working range indoor floor,
the air supply velocity can reduce 20% - 40%. After putting up the radiant cooling ceiling, it can slightly allow the high temperature increased, so the air supply
velocity can significantly reduce and person in the room still can feel comfortable.
