现在简介化霜功能:在空调室外机冷凝器盘管上设有一电敏热阻TR1。,当空调进行制热时,用来检测室外热交换器的温度。当室外温度降至-3℃左右时,该空调器进行制热时,室外机热交换器(原室外机冷凝器)上将结霜层(此时压缩机如果再工作下去,冷凝器内制冷剂有大部分不再蒸发吸热,而被压缩机吸入压缩,这样极容易“液击”而损坏压缩机),这时TR1将其阻值变化转为电压变化,再经R20分压传至芯片的25引脚,机组便进行除霜功能。当冷凝器上的霜全部化完,温度升至+6℃以上时,控制电路停止化霜,再继续进行制热,此过程为空调器的自动化霜过程。下面就由石家庄美的空调售后再来讲解一下空调器的自动化霜所需的条件:

1、化霜开始条件:室外热交换器铜管温度连续低于3℃的压缩机运行时间达到40min以上。

2、化霜结束条件:化霜时间达到10min;室外热交换器铜管壁温高于5℃

       除湿功能:空调器在两种模式下具有除湿功能:
a) 制冷模式 这是任何空调器都具有的模式,也是空调器最基本的功能。空调器制冷的过程必然伴随着除湿,潮湿空气通过空调器蒸发器后温度会大幅度下降,空气湿度处于一种过饱和状态,多余水汽以冷凝水的形式析出,凝结于蒸发器的翅片上,也就是“凝露”,等到制冷模式达到一定的平衡状态,空气湿度也就降到了一定的水平。


b) 独立除湿模式 这种方式被业内人士称为恒温除湿,它的基本原理是将通过蒸发器被冷却了的空气再加热到原来的温度,然后再送入室内,这样室内环境在湿度下降的情况下保持了相对恒定。
