Περίληψη:
The current study aims at the comparison of the field measurements at
the platforms of the Athens Metro with those recommended by
international standard thermal comfort and to the investigation of the
relationship of environmental parameters between platforms and the
outdoor space. The levels of air, operative and globe temperature as
well as air humidity and air velocity were continuously monitored at the
platform space of two stations with different depth and design features
in summer. The predicted mean vote (PMV) model and the predicted
percentage of dissatisfied (PPD) index were used. The results reveal
that the operative temperature at both stations is far from the
traditional still-air comfort zones. For the case of elevated air
movement of 1.2 ms(-1) and considering the occupants have local control
of air speed, 20.3% of the values at the station with the greatest
depth do not exceed the upper limit. Furthermore, 64% of the variation
in air temperature at the platform of the station with the smallest
depth is explained by outdoor air temperature, while the corresponding
percentage for the station with the greatest depth is 29%. Passengers
experience sudden change of air temperature and PMV, especially at the
station with the smallest depth, during their transition from the
platform to the interior of air-conditioned train carriages and vice
versa. (c) 2017 The Authors. Published by Elsevier Ltd.
