摘　　要：针对4种型号的轨道车辆空调用蓄冷装置样件进行放冷过程的性能测试,获得蓄冷装置在不同风速条件、不同环境温度和不同结构尺寸(扁管的厚度)下的总放冷量和放冷时间。根据实验结果分析比较了蓄冷换热器在不同条件下放冷效果的优劣,得到对放冷效果影响最大的因素为管厚和环境温度,风速对放冷效果的影响相比较小。The performance test of the four types of cold storage device was carried out,and the total cooling capacity and cooling time of the cold storage device under different wind speeds,different ambient temperatures and different structural sizes were obtained.According to the experimental results,the cooling effect of the exchanger was compared,and found that the tube thickness and air temperature had the greatest influence on the cooling effect,while the wind speed had little effect on it.
