Analytical Study of Cooling Performance with Frost Growth in a Refrigerator Truck Using R744
To analyze the cooling performance in the refrigerator truck using R744 according to frost growth, the analytical model of refrigeration system was developed under frost and non-frost condition using EES. The system performance was analyzed frost thickness and outdoor temperature in order to investigate the system performance characteristics with operating conditions. Besides, the system performance under frost condition was compared with that under non-frost condition. As a result, passing area of air and system performance was decreased as the frost grew. The frost thickness was 0.5 mm when the refrigerating capacity under frost condition was decreased by 16％ compared to that under non-frost condition. System COP under frost condition was also decreased by 18％.
