EN People more and more time spend in vehicles (cars, trains, planes, buses or subway). This is the reason why the thermal comfort has more and more paid attention. In one hand people try to make comfort (in each situation) whatever they are at home, office or in car. In the other hand the thermal cond[...]

EN During hot summer days outside temperature often exceeds 30°C. Without air condition system it is impossible to achieve temperature inside car compartment at the same level or lower than outside, even with high air flow. Driver 's efficiency researches indicate that it can be even 35% higher at +20°[...]

PL W ostatnich latach coraz większą wagę przywiązuje się do komfortu cieplnego w czasie podróży w samochodach, autobusach czy pociągach, a związane jest to z faktem, że spędzamy w nich coraz więcej czasu, a ponadto wzrasta średnia temperatura powietrza w miesiącach letnich. Wynika stąd potrzeba kolejny[...]
EN The thermal comfort during travel in cars, buses, and trains attracts more and more attention. This may be attributed to the fact that we are spending more time in travelling as well as summer time average temperature is still growing. This is the reason for requirements for additional research deve[...]
