摘要
为研究红外加热下冰层融化特性和除冰能效,搭建了红外线加热除冰实验台,采用实验的方法,研究融化过程中冰层内部温度变化,计算融冰速率及除冰能效。实验结果表明:利用红外线加热除冰,辐射能量被冰层表面接收后会以热传导的方式由表面向内部传递;融冰水蓄存会降低融冰速率,冰层厚度 5.8±0.2 cm条件下除冰时间增加 73%;红外加热管温度对除冰能效影响显著,低温加热器比高、中温加热器更节能,其平均能效比后者分别高 21%和 35%。
Abstract
To investigate the ice melting characteristics and deicing efficiency using infrared ray as heat source, a test-rig was built by which tests were conducted. The internal temperature of ice changes is investigated and the melting rate and energy efficiency of deicing are calculated during the process of melting. The experimental results show that infrared energy will transfer from the ice surface to the interior through conduction after being absorbed at the surface. Melt water accumulation will reduce the ice melting rate, making deicing time increase by 73% under the condition of the ice thickness of 5.8±0.2 cm. The temperature of infrared heating lamp has a significant effect on the energy efficiency of deicing. Compared with the high and medium temperature heaters, the low temperature heater is more energy-efficient, whose average energy efficiency of 21% and 35% are higher respectively than the former ones.
