چکیده
In this paper, a detailed combined 1-D model of HVAC systems vehicle were developed by using the LMS imagine LAB AMESIM software package. The numerical simulations considered for soaking and cool down analysis under different environmental conditions. thermal performance refrigerants as R-134a R-1234yf evaluated in terms energy consumption. According to simulation results, cabin air temperature values ranged from 49?C 57?C general. maximum increase value was about 22?C obtained 1000 W/m2 solar load. total time until reaching steady-state conditions target (23.5?C) all simulations. calculated 910 seconds load refrigerant loop. results also showed that although slightly better, can be used due its properties with acceptable performance. COP during cooldown 1.71 4.52 minimum cases which had higher interior values. data good agreement reference presented study. These are very important reducing considering consumption system
