Experimental Research on Thermal Deicing with EMU Model

为研究动车组高效节能的除冰方法,搭建动车模型热力除冰实验台,采用实验研究的方法,研究热风除冰的除冰速率和能耗,并分析不同除冰方式对室内温度的影响。创新性地提出把红外线加热技术应用于动车除冰,并且对红外线除冰进行了相应研究。实验结果表明:在实验设定工况下,红外线除冰最短需要66 min,而热风除冰最短则需要142 min,红外线除冰速率比热风除冰速率提高53.5%,所以红外线除冰的速率远高于热风除冰;红外线除冰在加热距离为0.5 m时,除冰能耗仅为6.6 kW·h,远低于热风除冰的耗能18.5 kW·h,此时红外线除冰的能耗为热风融冰能耗的35.7%。

In order to study the efficiency and energy saving of the deicing method for EMU,a thermal deicing experimental table of train model is set up. The method of experiment research is adopted to study the rate and energy consumption of the hot air deicing and analyze the influences of different deicing methods on indoor temperature. The infrared heating technology is proposed for deicing and its efficiency is studied. The experimental results show that under the experimental conditions,the shortest infrared deicing time is 66 min,while the shortest hot air deicing time requires 142 min. The rate of infrared deicing is 53. 5% higher than that of the hot air deicing. Therefore,the rate of infrared deicing is much higher than that of the hot air deicing. The infrared deicing energy consumption is only 6. 6 kW·h,when the infrared deicing distance is 0. 5 cm,covering 35. 7% of the energy consumption of the hot air melting.
