日立空调故障代码e3是为什么

   热泵型空调的制冷循环系统如附图所示,热泵式空调器因制冷、制热状态差别悬殊,仅靠电磁换向阀来切换制冷剂的流向,往往不可靠,因此,单向阀常用于热泵型空调器中,用来安全有效地切换制冷剂的流向。在制冷循环时,高、低压差较小,节流元件为主毛细管,而辅助毛细管被单向阀短路;在制热循环时,与辅助毛细管并联的单向阀不导通,节流元件为主毛细管与辅助毛细管串联,这样可增加节流元件的阻力,即增大制冷系统的高、低压差,降低空调内蒸发器在制冷时结霜室外热交换器的温度,从外界获取更多的热量,以达到制热的目的。当单向阀漏气时,制日立空调开机指示灯亮室外机不工作冷系统的高、低压压差下降,室外热交换器的温度上升,从外界获取的热量减少,导致制热量不足。当出现空调制冷正常、制热量不足故障时,通过检测系统运行时的压力,会发现低压侧压力上升,高、低压压差下降。

   变频空调故障原因大体可分为两类:一是外部原因或人为故障(特别是用户电源不日立空调开机指示灯亮室内机不工作多盈彩票注册正常,电压偏高或偏低引起的),二是机器本身故障(分制冷和电气系统故障)。对于机器本身故障,应先排除制冷系统故障,判断系统是否漏氟、管路是否堵塞、冷凝器是否散热不良等,其次检查是否为电源的问题,或是其他电控有问题,如电动机绕组是否异常、继电器是否接触不良、功率模块是否击穿等。
