摘　　要：据欧洲标准EN441和用户要求,设计并建造了一套食品展示柜热工性能测试试验室。环境室采用全孔板送风,试验区域实现了风向平行于冷藏展示柜开放平面以及在纵向轴线处的速度达到规定要求。展示柜热工性能测试试验时温度控制精度达到±0.3℃,相对湿度控制精度为±3%。Based on European Standard EN441 and user＇s requests, an experiment system for measuring the thermal performance of refrigerated display cabinet is designed and constructed. The whole perforated plate air supply mode, during the testing region, the air movement parallel to the plane of the refrigeration cabinet display opening and to the longitudinal axis, and velocity achieve rigorous request. During the testing of cabinet, it shows the temperature control precision of±0.3℃, the relative humidity control precision of±3%.
