摘要: 本文主要探討人口對室內空氣品質的影響。假使一地人數多且長時間地處於室內,則人體的發熱量與釋放出氣體的量應會對室內的氣體濃度造成一定的影響。在人排出的氣體中,對環境影響較為重要的有二氧化碳和水蒸氣,且人體可以視為一發熱源,因此將人當為最主要的源項配合其它邊界條件加以探討。不同的公共場合伴隨著不同的建議人數與不同的最低換氣量。而本研究探討在建議的人數與符合標準的換氣量下,室內空間的氣體有無符合法定含量值。
The study focuses on the influence by the number of people to the indoor air quality. If there are a lot of people who stay too long in the interior spaces, the heat and gases released by people must affect the environment to a certain extent. The most influential gases released by people are carbon-dioxide and water vapor, and people can be regarded as heat sources. Thus, this research regards people as the main source term and calculates the fluid field with boundary conditions. In different places, there are different maximum capacity and minimum ventilation allowed. This research is mainly focusing on limiting the indoor gases below regulation amount, under the condition that the exaulting volume matches the standard for certain recommended capacity.
