서울지역 지하철 환승역사의 하절기 온열환경 특성 연구 = Characteristics of Thermal Environment in Subway Stations of Seoul during Summer Time

다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate the thermal environment of subway stations in Seoul and to suggest ways to improve the thermal environment and cooling energy during summer time. Major thermal environmental indexes were measured in six subway stations of three transit stations during summer time. The temperatures and relative humidities over the design conditions were observed in many concourses and platforms of the subway stations and the thermal environments of platforms were comparatively worse than concourses in most stations. Predicted Mean Vote(PMV) values were ranged over 1, which indicates “slightly warm”, in almost all stations. The air temperatures of subway stations during non-operating hour were up to 6.6°C higher than outdoor air, which presumably caused by the thermal storage during day time. The high enthalpy of subway station during non-operating hour is assumed to provide bad thermal environments to passengers in the early morning and also to cause more cooling energy during morning rush hour. Pre-cooling using low-enthalpy outdoor air before the early morning operation should be considered to improve thermal comfort and to save cooling energy even during summer time.
