Μελέτη του θερμικού ισοζυγίου του ανθρώπου σε μη σταθερές συνθήκες
Summary:
The current thesis aims to investigate the thermal comfort of the human body in
a "medium" type of person to a warm outdoor environment through the study of
heat balance, using the dynamic model IMEM (Instationary Munich Energy balance
Model). The study was performed by varying the intensity of the activity, the
degree of exposure to direct solar activity and the meteorological data. The
outcoming results are the thermophysiological parameters, the heat fluxes
between the human body and the ambient environment and the biometeorological
index PET (Physiological Equivalent Temperature). The study through the process
of simulation is completed in three phases, for ten hot days.
The first phase of the simulation, with the non-constant model IMEM, begins
with the exit of the subject from an interior space to the outside environment,
situated in the shade at low levels of activity. During the second phase of the
process, the person is considered to have been lodged in the activity of
walking while constantly exposed to direct sunlight. During the third stage of
the simulation, the concerned person follows mild activity in the shade.
By the examination of the parameters it was found that body temperatures and
particularly the mean skin temperature is relevant for the calculation of the
thermal balance of the human body. This result affects the course of the heat
gains or losses through radiation, convection, diffusion of water vapor and
evaporation of sweat for the three phases of the simulation. Finally, the
mapping of the thermal burden of the human body appears in the evolution of the
values of the biometeorological index PET.
