摘要： 利用改进的双流体(MTF)模型对立式敞开型陈列柜冷风幕及其四周气体流动和传热进行数值模拟，从而确定陈列柜的漏风量.通过MTF得到的结果训练并验证针对漏风量的自适应支持向量机(ASVM)算法，建立陈列柜性能的优化函数.实验测试验证结果表明，优化后的陈列柜融霜后的凝结水质量和单位展示面积每日耗电量分别减少39.2%和19.3%，明显改善了漏风.

Abstract: Using the modified twofluid (MTF) model, the flow and heat transfer of air curtain and air around were simulated. Moreover, the air leakage quantity of the open vertical display cases was also confirmed. Using the results calculated by the MTF model as the testing and validation data, the optimized function was solved by adaptive support vector machine (ASVM) algorithm. By the validated experimental data, the defrosting water quantity and TEC/TDA of optimum display case are reduced by 39.2% and 19.3% respectively, which reduces the air leakage significantly.
