“…Refrigerated trucks in operation are not always fully loaded, and different cargoes may require different stacking methods. Therefore, the temperature field where a cargo is located should not be compared with the standard temperature field of the entire truck, but with the same volume as the stacking area [4]. The standard temperature field of the refrigerated truck is called the measured area, which is equal to the volume of this same area.…”

“…Refrigerated trucks are an important means of land transportation. During transportation, the internal temperature field within a refrigerated truck is affected by the external environment, internal structures, and the stacking methods used [4,5]. Many scholars have used computational fluid dynamics (CFD) to study refrigerated trucks, and the results of their work have helped to overcome the shortcomings of traditional theoretical analysis and enable simpler, more effective computation [6,7].…”

“…Scholars have also conducted numerical simulations of transport-compartment temperature fields based on airflow velocity, stacking patterns, and airflow organization [8]. Several temperature and humidity sensors in a refrigerated truck are usually managed at certain periods to simulate the corresponding temperature and humidity curves [4,9,10]. The analysis of turbulent flow with complex heat transfer in a refrigerated body was conducted by Kayansayan et al [11].…”

In this study, we constructed a calculation model to determine the internal temperature field distribution in a medium-sized refrigeration truck with the dimensions of 4.1 m × 2.2 m × 2.2 m. Wind speed, air temperature, and carcass temperature were designated as the initial conditions. The k-ε model of computational fluid dynamics was used to simulate different wind speeds and ventilation duct settings on the carriage. Additionally, under specific boundary conditions, the speed of the air outlet, the types of ventilation ducts, and the carcass loads were all varied to determine the uniformity of the temperature field. The results showed that, when the air outlet speed was 5 m/s, the temperature field in the refrigerated truck was relatively more uniform. The simulated results were in good agreement with the measured results. The average absolute error was 0.35 °C, and the average relative error was 9.23%.

“…Most of them optimize ORDC when it was full with package. The structure [5,6], the air guiding strip [2], and the phase change material (PCM) [3,4] can be found to improve the ORDC performance. For example, Wu et al [5] discussed the effect of porosity of the perforated back panel (PBP) (0% -7%) on average temperature.…”

Open refrigerated display cabinet (ORDC) is widely used in supermarket. It is very convenient for customer to take package. Therefore, the package is not full in ORDC in most time. And the different package arrangement could directly affect ORDC performance. Therefore, this paper optimizes the ORDC and aims to find an optimal structure to meet all different package arrangements. By using the validated model, the windshield and airfoil were employed. Results showed the optimal windshield width, the distance of from evaporator to windshield, and the distance from airfoil structure to shelf edge were 70 mm, 210 mm, and 80 mm, respectively. Under different package arrangements, the average temperature only varied 0.8 °C and the energy consumption 9%. The results obtained in this paper could provide guidance to optimize ORDC.
