家电维修

维修空调日期:2022年3月24日

品牌型号:5匹吸顶式空调,型号看不清了

故障现象:空调不制冷,但室内外风机运行,

故障部位:制冷系统、电控系统、缺氟等

维修空调过程:先检查空调外机没有热风,拆下外机盖,空调电源电压正常,空调压缩机没有启动,刚怀疑压缩机坏,不小心手背碰到外机里的铁皮手有点麻,当即断定机子有漏电,拿电笔试探,果然是机壳带电。看了看室内电源布线,没有发现地线。缩小检查范围,断了外机三条线,再用电笔试探,机壳不带电了,在使中压缩机可以工作,但不能长时间就停机了,现次怀疑压缩机损坏漏电的,为了减小拆卸,只去了压缩机的线,再次上电,发现机壳还带电,漏电原因跟压缩机机没有关系,就从火线到各处的接头拆除,最后是发现压缩机启动电容漏电的,拆下电容测量容量没有小只是漏电,直接换了一个35UF的上去试机,一切正常情工作。

维修空调结果:换压缩机启动电容。一切正常。启动电容在高压时漏电,造成有效容量降低,使压缩机紧缺少动力而停机、压缩机会因过热保护

经验:平时空调维修像压缩机不启动,一般直接用相同的压缩机启动器直接更换,大部分都是次部件故障。

英文译文:

Brand Model: 5 HVAC. Model is hard to see

Failure phenomenon: air-conditioning does not refrigeration but indoor and outdoor fan operation

Trouble spots: refrigeration system electric control system fluoride deficiency etc.

Maintenance of air conditioning process: first check the outside machine without hot air remove the outside machine cover power supply normal compressor did not start just suspected that the compressor is bad accidentally hit the back of the hand in the outside machine iron hand a little hemp immediately concluded that the machine has a leakage take a pen test as expected is the case live. Looked at the indoor power wiring did not find ground. In order to reduce the disassembly of the compressor only to go to the compressor line power again found that the chassis is still live the reason for leakage has nothing to do with the compressor to remove the starting capacitor leakage the last is found that the compressor capacitance measurement capacity is not small but leakage directly replaced by a 35UF test machine all normal work.

Repair air conditioning results: change compressor start capacitor. Everything is normal. Starting capacitor at high voltage leakage resulting in a reduction in effective capacity so that the compressor tight lack of power and shutdown compressor overheat protection

Experience: Usually air conditioning maintenance like compressor does not start usually directly with the same compressor starter direct replacement most of them are secondary components failure.
