Field study on thermal comfort of passenger at high-speed railway station in transition season

摘要

Previous studies on thermal comfort have been mainly conducted in climate chamber, summer and winter in air-conditioned buildings and summer in naturally ventilated buildings, but rarely in transition season (non-air conditioned environment) in air-conditioned buildings. For buildings with large space and high density of people like in high-speed rail station, the thermal comfort of passengers in waiting room in non-air conditioned condition should be a concern. According to ISO 7730 and ASHRAE 55, field studies have been carried out in two high-speed railway stations during late spring and late fall in Shandong and Hebei, two provinces located in the cold region of China, using a subjective questionnaire survey simultaneously with thermal environmental parameter monitoring.
