碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系 === 107 === In this thesis, the commercial software ANSYS Fluent was employed to study the air conditioning problem of airport waiting room. The purpose of the present study is to provide some basic guides for the environmental improvement of the waiting room in order to improve the comfortability for passengers by an economic and efficient way. We first introduce the factors that cause the hot atmosphere, including the leakage of outdoor air, the thermal radiation from the sun through glass windows, and the limits of air conditioning capacity. The simulation is implemented based on a typical weather of summer afternoon in Taoyuan City, Taiwan. To improve the comfortability for passengers, three approaches were proposed including the adjustment of velocity of cooling fans, the arrangement of spatial pattern, and the installation of air curtain at the doors connecting to the boarding gate. The results show that the arrangement of spatial pattern would decrease the sun radiation significantly. However, the temperature near the door is still high because of the permeation of outdoor air. Also, the landscape view was affected dramatically with the approach. For the third approach, it is found that the installation of air curtain would effectively decrease the indoor temperature as long as the hot air can be completely isolated from outdoor. In this situation, the energy for cooling can be saved significantly. Nevertheless, the result also reveals that the installation of air curtain is not arbitrary but must be designed with an optimal operating conditions, which suggests that some automatic control functions can be considered in the practical engineering, such as the temperature sensors and flow rate adjustment. In conclusion, this research has implemented a series of CFD simulations for the airport waiting room and the results have provided some useful guides for the improvement of ability for passengers’ comfort.
