維修空調日期:2022年3月24日
品牌型號:5匹吸頂式空調,型號看不清了
故障現象:空調不制冷,但室內外風機運行,
故障部位:制冷系統、電控系統、缺氟等
維修空調過程:先檢查空調外機沒有熱風,拆下外機蓋,空調電源電壓正常,空調壓縮機沒有啟動,剛懷疑壓縮機壞,不小心手背碰到外機里的鐵皮手有點麻,當即斷定機子有漏電,拿電筆試探,果然是機殼帶電??戳丝词覂入娫床季€,沒有發現地線??s小檢查范圍,斷了外機三條線,再用電筆試探,機殼不帶電了,在使中壓縮機可以工作,但不能長時間就停機了,現次懷疑壓縮機損壞漏電的,為了減小拆卸,只去了壓縮機的線,再次上電,發現機殼還帶電,漏電原因跟壓縮機機沒有關系,就從火線到各處的接頭拆除,最后是發現壓縮機啟動電容漏電的,拆下電容測量容量沒有小只是漏電,直接換了一個35UF的上去試機,一切正常情工作。
維修空調結果:換壓縮機啟動電容。一切正常。啟動電容在高壓時漏電,造成有效容量降低,使壓縮機緊缺少動力而停機、壓縮機會因過熱保護
經驗:平時空調維修像壓縮機不啟動,一般直接用相同的壓縮機啟動器直接更換,大部分都是次部件故障。
英文譯文:
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.
