The climate in the passenger compartment is very inhomogeneous. The varying radiation
from the sun and the influence of inhomogeneous air temperature and air velocity from the
vehicle’s ventilation or air conditioning system creates a climate that may vary considerably
in space and time.
Analyzing the cartographies we can observe also the influence of the sun position on the
temperature of the interior components, and also on the car occupants. Analysing the figure 6
we can see that the temperature of the interior components that are in direct contact with the
back passenger(rear seat) are lower that those of the components that are in contact with the
driver (front seat).
From figures 8 and 9 we can observe that the back passenger reach a better thermal comfort
state earlier than the driver. After 20 minutes the PMV index is about 1.06 for passenger and
the value obtained of the driver is after 25 minutes. Also we can observe, comparing the
obtained results with the values given in Figure 2, that after whole simulation completed, the
back passenger is in the neutral thermal comfort zone, while the driver feels slightly cool.
The efficiency of the HVAC system is evaluated by taking into account the equivalent
temperature, the sun position, the air velocity and the surface temperature of clothing of the
passengers etc.
