| Summary: | 碩士 === 國立臺北科技大學 === 建築與都市設計研究所 === 98 === The purpose of this study is to analyse how the enzyme particles emitted during feed-in process at traditional enzyme preparation industry workspace and the distribution of particulate matters with different interior form types. Eventually we can obtain the optimal improvement to keep a certain area free from particle contamination, so as to reduce occupational exposure to enzyme particulate pollutants, by means of architectural design messures with building openings, placing air-condition pipeline and changing the interior space-based structure in the parameters.
By CFD-simulating the trend of airflow field of indoor space,the concentration distribution of particulate pollutants in different changes in parameters is to analyze how the difference of inlet wind direction and interior typology effect the spread of particulate pollutants. Different indoor ventilation characteristics will cause different efficiencies of pollution exclusion of indoor environmental. According to numerical simulations, conclusions and suggestions are given as follow:
(1)The simulation resullts show that indoor pollutants concentration may cause an accumulation by the vortex of indoor airflow and it leads to the difficulty to disperse the concentration in the certain region.
(2)Different air-conditioned pipeline arrangements cause a considerable impact of the sensitive airflow field and will be able to obtain the optimal configuration program of air-conditioning.
(3)Changing the interior spatical form type for effecting the airflow field, it could adjust the present status of the indoor particulate pollutants distribution, and the shortest path to exclude the particles and a optimal case can be obtained.
(4)To pursue a healthy indoor air quality, the air-conditioning pipeline arrangement, indoor facilities, material removal and interior form types should be carefully considered at the initial architectural design process and pre-existing buildings renovation.
