Abstract :Air conditioning systems used for the cooling of vehicles to create a uniform temperature distribution in terms of providing thermal comfort to people is an important parameter. From this point, realization of appropriate computer simulations of these systems during the design phase provides a significant convenience to the success of the design. In this study, determination of the time required to reduce the bus indoor initial temperature at  310 K insert ignore into journalissuearticles values( 37 °C); of a bus for 49 passengers including the driver to  293 K insert ignore into journalissuearticles values( 20 °C); gradually with a uniform temperature distribution and the temperature, pressure and velocity distribution were analyzed using finite elements method insert ignore into journalissuearticles values(ANSYS);. In finite element program, developed for this purpose indoor thermal load of 49 people including the driver in the bus has been calculated by using thermal mannequin modeling, the internal conditions were integrated to real conditions. As a result of the temperature pressure and velocity distribution graphics obtained at 5 minutes intervals depending on real conditions case scenario in ANSYS program, it was determined that in about 15 minutes the indoor temperature distribution of the bus has reached to  293 K value uniformly
