摘要:

近年来,无霜冰箱受到欢迎,一般无霜冰箱都是采用风冷设计的冰箱,风冷冰箱的原理是利用空气进行制冷,高温空气流经内置的蒸发器(与冰箱内壁分开)时,由于空气温度高、蒸发器温度低,两者直接发生热交换,空气的温度就会降低。同时,冷气被吹入冰箱。风冷冰箱就是通过这种不断的循环方式,来降低冰箱的温度。然而,空气中永远存在着水蒸气,水蒸气遇冷会凝结,所以冰箱中只要存在着热交换,就会有霜的形成。那么,霜去了哪里呢?

近年来,无霜冰箱受到欢迎,一般无霜冰箱都是采用风冷设计的冰箱,风冷冰箱的原理是利用空气进行制冷,高温空气流经内置的蒸发器(与冰箱内壁分开)时,由于空气温度高、蒸发器温度低,两者直接发生热交换,空气的温度就会降低。同时,冷气被吹入冰箱。风冷冰箱就是通过这种不断的循环方式,来降低冰箱的温度。 然而,空气中永远存在着水蒸气,水蒸气遇冷会凝结,所以冰箱中只要存在着热交换,就会有霜的形成。那么,霜去了哪里呢?事实上,风冷冰箱并不是无霜,而是霜凝结在蒸发器的上面,因为它在冰箱的内部,我们打开冰箱门无法直接看到,所以形象地称为无霜。针对这部分霜,目前主流的技术是通过热蒸发来去除,就是当冰箱工作一段时间之后(一般8小时左右),冰箱暂停制冷,启动除霜加热系统。凝结的霜受热后会变成水,再通过专用的导管排出(或直接蒸发成水蒸气),这个工作是冰箱自动完成的,不需要用户手动处理。因此,业界又把无霜冰箱形象称为自动除霜。(function(){document.domain=qq、com;var
