摘要：Air conditioning (AC) installed on vehicles must insure passenger com-fort no matter the year season. To this end we make a series of meas-urements and readings of the interior temperature of vehicles with such AC installations. This work presents a study on the AC efficiency on public transportation vehicles, namely articulated busses. Our study shows that the AC appliances installed on the examined busses were not able to ensure the temperature assumed by the AC contractors. We propose that, for public transportation, AC installations should be sized accordingly to the vehicle’s interior volume and to the transportation’s body thermic insulation.
