摘要:
送回风静压空间和风道结构的作用,可有效改善冷冻冷藏柜内部气流组织,优化其热环境性能. 以冷藏柜为主要研究对象,针对上送上回送风方式,探索有无送回风静压空间对冷藏柜的热环境影响,并改变风道结构,即送风板变截面角度(θ=0°,1.5°,3°)及送风板穿孔率(φ=5%,10%,15%),建立11种模型分析比较,实测典型模型与改进模型在标准工况下的温度场和速度场,并与模拟结果进行对比. 进而提出热环境性能的评价指标-垂面温度/速度均匀系数对不同风道结构模拟与实测模型进行评价分析,以反映冷藏柜热环境的理想程度,并选取最优结构模型. 数值模拟和试验验证结果表明,在上送上回送风方式下且有静压空间,θ=1.5°,φ=10%时,冷藏柜气流组织合理,热环境性能较为理想.
Abstract:
The compound effect of air duct configurations and static pressure space can noticeably improve the internal airflow distribution and optimize the thermal performance of the cold storage cabinet. This paper studies the cold storage cabinet with or not static pressure space mode of upper supply and upper return and changing the air duct configuration. Eleven numerical models are proposed and analyzed by changing the angle of the air supply plate(θ=0°,θ=1.5°,θ=3°)and perforation ratio of the air supply plate(φ=5%,φ=10%,φ=15%). The velocity,temperature field of the cold storage cabinet using the improved model and typical model are measured and compared. Furthermore,in order to evaluate the satisfaction degree of the thermal performance of the cold storage cabinet,evaluation index is proposed to evaluate the effect of static pressure space and air duct configuration. The optimal model is found after evaluate comparison,that is the airflow distribution and thermal performance are the best with the air supply static pressure space and the air supply plate angle θ at 1.5° and the perforation ratio of the air supply plate φ at 10%.
