碩士 === 南台科技大學 === 機械工程系 === 99 === Owing to the environmental changes and energy shortage, Energy-saving and light-weighted are the goals that the R&D goes in for and develops the techniques of EV (Electrical Vehicles) and Hybrid cars. Therefore, the development of light-weighted EVs is becoming the trend for accommodating the changes. However, most of light-weighted EVs are not equipped with the air-conditioning systems under the condition of the reduction in energy-consuming and the weight of cars. According to some studies, some researchers provided the ideas of the air-conditioning seat. They utilized the mini-sized air-conditioners to collocate with the car seat and the outer cover to form a personal space, where the riders could be surrounded with cool air. In addition, using this system can lower the consumption of energy for reducing the air-condition spaces and lightening the weights. In this study, we focus on the data of the air-conditioning seat by using STAR-CCM+ CFD analysis software to explore the differences between the data given by the software and the experiments by comparison. Hence, through these analyses, we can obtain the data of the Internal flow and the efficiency of temperature-decreasing. Moreover, we also implement the theoretical analysis to examine whether the mini-sized air-conditioners could discharge the heat of the air-condition space. The results show that using air-conditioning seat yields excellent temperature-decreasing phenomena. Furthermore, we could also find out the best positions of the air outlet vents by analyzing the variations of both Internal flow and temperature fields
