【摘要】:為研究紅外加熱下冰層融化特性和除冰能效,搭建了紅外線加熱除冰實驗臺,采用實驗的方法,研究融化過程中冰層內(nèi)部溫度變化,計算融冰速率及除冰能效。實驗結(jié)果表明:利用紅外線加熱除冰,輻射能量被冰層表面接收后會以熱傳導(dǎo)的方式由表面向內(nèi)部傳遞;融冰水蓄存會降低融冰速率,冰層厚度5.8±0.2 cm條件下除冰時間增加73%;紅外加熱管溫度對除冰能效影響顯著,低溫加熱器比高、中溫加熱器更節(jié)能,其平均能效比后者分別高21%和35%。
[Abstract]:In order to study the melting characteristics and deicing efficiency of ice layer under infrared heating, an experimental platform for deicing by infrared heating was set up, and the internal temperature change of ice layer during melting process was studied by the method of experiment. The experimental results show that the radiation energy is transferred from the surface to the interior by heat conduction when the radiation energy is received by the ice surface. Thawing water storage decreased the melting rate, and the deicing time increased by 73 when the ice thickness was 5.8 鹵0.2 cm. The temperature of infrared heating tube has a significant effect on deicing efficiency. The ratio of low temperature heater to medium temperature heater is higher than that of medium temperature heater, and its average energy efficiency is 21% and 35% higher than that of the latter, respectively.
