| Summary: | 碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 104 === Today in Taiwan, a large number of jobs concentrated in the city, making the city building patterns for commercial and residential high floor and toward the development of ultra-high floor, build a large number of high floors of the building were able to meet the citys needs. Meanwhile, in order to solve the parking problem on a high floor of the building, the basement of the building regulations drawn Parking gradually become an inevitable trend, but the basement belong to a confined space, the steam locomotive emissions from the exhaust gas can not be effectively discharged underground parking lot, resulting in the underground car park air quality is not good. At present, the air quality in the underground car park of the building in the form of research is the lack of the research on this topic in a new building, New Taipei City selected as a case by CFD simulation of underground parking of the vehicle emissions of air pollutants concentration (CO) and an underground car park ventilation the amount of ventilation equipment, reckoning the trends of air quality in underground car park in order to understand the relevance of the underground car park of carbon monoxide concentration and ventilation of ventilation equipment and the number of vehicles between. In this study, airflow simulation software CFD simulations at different air flow and operation mode, air distribution and the status of the carbon monoxide concentration change, and may actually while launching the maximum number of vehicles in the car park of as a basis, the import simulation, so that the simulation results can be closer practical, and review existing regulations for underground parking exhaust volume predetermined value is appropriate, the simulation results in the average concentration of carbon monoxide in line with one five-meter-high indoor air quality requirements, the carbon monoxide concentration in the whole parking lot is less than requested.
