Based on European Standard EN441-2,an experimental system for measuring the thermal properties of refrigerated display cabinet is designed and constructed.Considering the practice requirement from user,the air distribution analysis is done under various air-flows forms in the testing room.The FLUENT is used,which is one of the CFD simulation software,to verify the design method of air movement.A series of tests required for laboratory quality regulation are carried out to meet the need of wanted velocity or temperature.
