Optimizing the Performance of Open-Type Refrigerated Display Cabinets: Block Schemes and Key Tasks

The performance of open-type refrigerated display cabinets has been rigorously examined through the development and application of two comprehensive block schemes, which integrate numerical simulations with experimental research.Central to these schemes is the use of a simplified two-dimensional, time-dependent computational fluid dynamics (CFD) model, designed to evaluate and optimize airflow patterns, thermal behavior, and energy efficiency within the cabinets.The numerical simulations, validated against experimental data, demonstrate that the strategic design and configuration of air curtains and internal components significantly mitigate the impact of ambient air, thereby reducing temperature fluctuations that are critical for maintaining food quality and safety.The application of these block schemes has been shown to enhance energy efficiency and reduce electrical consumption, contributing to operational cost savings.The strong correlation between CFD results and experimental findings underscores the reliability of these models for accurately representing real-world conditions.Future investigations could benefit from exploring additional geometric configurations and incorporating more advanced CFD techniques to further refine the performance of refrigerated display systems.This integrated approach offers a robust framework for improving the operational effectiveness and food preservation capabilities of open-type refrigerated display cabinets.
