| Abstract |
Even metro subway have lots of benefits, such as advanced energy efficiency, substitution of ground transportations and improve air environment, the thermal environment of subway, which had opened earlier without air conditioning system, is getting worse because of increasing passenger number and decrepitude. Especially, they are spending lots of money to cooling and air conditioning system during summer season. According to this study, most thermal environments of the Subway line 1 stations in Busan have poor condition except some station. Therefore, in this study, Bujeon station, which is required to improve thermal environment, have been surveyed thermal environment of platforms. Also possibilities of applications of natural energy, which are night purge and ground water to get effect of platform using outdoor pre-cooling equipments, have been examined. Finally, this study has provided basic data for air cooling system design to improve thermal environment of subway station platforms through the results of examination. |
