Study on Optimization of Ventilation Effect of Condensation Phenomenon in Outdoor RMU Based on Fluent
Condensation is one of the main challenges to the safe operation of outdoor RMU. Enhancing natural ventilation can reduce the relative humidity inside the cabinet, preventing condensation formation. Considering the structural characteristics of outdoor RMU, establish a 3D model and conduct ventilation simulation using Fluent to analyze the impact of airflow velocity and enclosure dimensions on ventilation effectiveness. The results show that there is minimal variation in airflow velocity within the compartments of outdoor RMU when external wind speed changes. Under similar wind speeds, widening the enclosure is more effective than increasing its height in reducing the relative humidity inside the outdoor RMU.
