The objective of this paper is to analyse the
current state of the constructional design
and operational conditions of air
-
conditioning device in passenger cars. The research was focused
on the function of air
-
conditioning equipment of passenger cars Skoda and KIA in various modes
of operation during
the winter, spring and summer season at different levels of air conditioning
(without air
-
conditioning, minimum, medium and maximum level). Air temperature, air
humidity, globe temperature, CO
2
concentration, dust concentration and noise inside the cabin
w
ere measured. Solar radiation plays a big role to rise up temperature inside the cabin. It resulted
in the higher values of globe temperature than temperature of the air. The results of the
measurements showed that CO
2
values were significantly lower than
2,500
ppm at minimum air
-
conditioning, lower than 600 ppm at medium and lower than 500
ppm at maximum level of air
-
conditioning. For all vehicles, dust concentration was greater when it measured with the air
conditioning switched off than with the air con
ditioning system turned on. The measurements
confirmed that the total dust concentration was not more than 47

. The noise levels ranged from 49.1 to 68.7 dB(A). The air

conditioning had very
positive impact on the inside comfort in car cabins from all points of view
during all periods of the year.
