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°C than at +35°C. Decrease of efficiency at +5°C can be the same as that at +35°C. Usage of air condition system is the only way to achieve internal temperature lower than external one. The heat flux which should be transferred from the car cabin is about 2 kW. There is no problem to reject even higher heat flux from cabin. The problem is how to assure thermal comfort for passengers in so small space like car compartment. The thermal comfort usually means that near skin air temperature is about 20-22°C and air velocity is below 0.5 m/s. In this paper first analysis of numerical modelling of air flow inside car compartment are presented. Two types are considered: first one with 2 m/s velocity with inlets situated at front cowl section, front of dashboard and near feet. Second one with 4 m/s velocity with inlets situated at front cowl section and near foot.
