空调移机频发哪些故障?

来源: 日期:2017-12-25 发布人:admin
制冷系统故障是我们维修当中常风的故障,故障现象也是五花八门,但还是有规律可循,有经验可借鉴。下面介绍的是空调制冷系统故障的检查步骤,我们维修时应顺着此思路进行检修。
The failure of the refrigeration system is the common Wind fault in our maintenance, and the failure phenomenon is also various. However, there are still rules to follow and experience can be used for reference. The following is the inspection steps of the failure of the air conditioning refrigeration system, and we should follow this train of thought for maintenance.
一、制冷系统检修要点
1. The main points of the maintenance of the refrigeration system
1、观察内外机的工作情况:如指示灯板的显示情况,内机是否工作,风速输出是否正常,外机风扇、压缩机是否运行,从而判断是电器问题还是系统问题导致的不制冷。
1, observe the inside and outside machine's work: such as the indication of the indicator panel, whether the internal machine works, whether the output of the wind speed is normal, whether the external fan or compressor is running, so as to determine whether the electrical problem or the system problem leads to no refrigeration.
2、检测空调器各项数据:空调流水情况,一般内机滴水连续空调正常,但受环境湿度、温度影响只能作为一参考值。
2, detect the data of air conditioners: air conditioning and water flow. Generally, internal dripping water and continuous air-conditioner are normal, but affected by environmental humidity and temperature, they can only serve as a reference value.
二、制冷系统故障类型
Two. Type of failure of refrigeration system
1、制冷系统堵:
1, refrigeration system plugging:
常常发生在毛细管及干燥过滤器处,因为这两个地方是系统中狭窄的地方,常见的堵塞原因有三种:脏堵、冰堵及焊堵。
Often occurs in capillary and dry filter, because these two places are the narrowest part of the system. There are three reasons for common clogging: dirty plugging, ice blocking and welding blockage.
2、制冷系统漏:
2. Leakage of refrigeration system:
空调制冷制热的载体是制冷剂,如系统出现漏点,制冷剂泄漏则空调制冷差或完全不制冷,而空调器出现泄漏的地方主要集中在两器的各焊接头、毛细管焊接处、压缩机吸排气管、喇叭口、铜钠子裂、连接管等处,要检查时可先进行目测,重点检查连接管各接头处,泄漏处一般都有油迹。
Carrier air conditioning heating and cooling system is refrigerant, such as leakage, leakage of refrigerant is poor or no air conditioning refrigeration and air conditioning, the leaking place mainly in two for the welding, welding, capillary suction, exhaust pipe, sodium copper bell crack and the connecting pipe etc., to when the first visual inspection, the joint inspection of key connection pipe, the leak is generally oil.
3、四通阀故障:
3, four valve failure:
通常发生在制热时,四通阀吸合不好、串气或卡死,引起制热性能差,在判断时可对四通阀通断电听吸合是否良好,在维修时可通过反复给四通阀通电或轻轻敲打四通阀使其复位。
Usually occurs in the heating time, four valve is not good, so or stuck, causing the heating performance is poor, the four valve on-off to pull is good in judgment, at the time of repair by repeatedly to the four valve energized or tap four valve to reset.
