| Summary: | 碩士 === 國立臺灣科技大學 === 建築系 === 92 === The sewerage system of a building has a concern in the environmental public health and sanitation. Especially under the trend and development of towering buildings and high-density of population, inappropriate sewerage system can cause many problems, including sanitary facilities trap seal water drains,bad drainage and so on. Particularly the epidemic disease — SARS that evoked international panic in 2002, after some research and investigation, researchers confirmed that sewerage system of a building is one of the channels of infection. Therefore, to ensure a building has the most appropriate sewerage system and to prevent lethal and contagious virus from spreading are the most important functions that an appropriate sewerage system has to cover.
This research continues domestic experiences on buildings’ sewerage system to keep making research project and plan on the aerating quality and function the ventilates performance of vertical drainpipe that affects the function of trap in sanitary facilities, and also to keep experimental analysis on air pressure variation inside the single drainpipe system in order to establish a thorough and complete predictable mode on them.In the meantime, based on the vertical dual drainpipe that is commonly and domestically used to build up an experimental system; with the reference from experimental parameter, we combine the predictive mode on single vertical drainpipe, and expand to estimate the air pressure variation maximum range on dual drainpipe as the further evaluation on the drainage system and as the theory foundation on piping design and arrangement.
The research results found are as below:
1.To complete the proof and experiment of air pressure variation inside the vertical single drainpipe and to establish distribution predictive mode.
2.To establish the experimental equipment on duel vertical aerating drainpipe, and to confirm it qualifies with closeness that is required in this experimental system.
3.To finish analysis on air pressure variation experiments and function of dual pipes drainage system.
4.To set up the predictable mode of air pressure variation maximum range.
5.To complete the experimental proof and discussion on the air-pressure variation predictive mode between single vertical pipe and dual vertical pipes.
