| 英文摘要: |
| The research and development of the refrigerated display cabinet has a long cycle and high cost by experience
and simple calculation. The research and development of the refrigerated display cabinet based on CFD technology was
presented, and the CFD technology, the structure of closed display cabinets and its thermal load were introduced. The
temperature field and flow field inside the closed refrigerated display cabinet was simulated by the finite volume method
with an unsteady three-dimension model and compiling UDF ( User-Defined Function) procedure. The application
results show that the method not only has high efficiency and low energy consumption, and can master the temperature
distribution characteristics and improve airflow organization inside the refrigerated display cabinet. Therefore. it has
improved the uniformity of temperature distribution and effect of food preservation. |
