  日立中央空調不制冷?可能是銅管泄露造成的！下面云南日立中央空調的小編給大家闡述一下：銅管泄露是日立中央空調的致命缺陷，一旦泄露，空調的制冷劑將全部溢出，空調由于缺乏傳熱介質而使 空調器失效。

  1、制(zhi)造方面的(de)原因
  我國標準(zhun)規定了銅(tong)管(guan)必須(xu)進行(xing)渦流(liu)探(tan)傷(shang)。這(zhe)項要(yao)求在正規大(da)型銅(tong)管(guan)廠是能夠充分保證的，因(yin)為探(tan)傷(shang)是通(tong)過在線(xian)檢(jian)測的。有的銅(tong)管(guan)廠則(ze)不是這(zhe)樣，不經過渦流(liu)探(tan)傷(shang)或者是用低標準(zhun)的渦流(liu)探(tan)傷(shang)儀(yi)抽檢(jian)，這(zhe)樣銅(tong)管(guan)就存在超標的缺陷(xian)漏檢(jian)，或未檢(jian)測造成安裝(zhuang)日立中央空(kong)調使用時(shi)空(kong)調制冷(leng)劑泄露。

  2、安(an)裝的(de)問題
  在(zai)安裝云南日(ri)立中央空調的過程中要(yao)經過彎管(guan)、漲(zhang)(zhang)管(guan)、擴口(kou)、焊接等環節。在(zai)彎管(guan)的過程中由(you)于(yu)(yu)彎曲部(bu)分要(yao)經過局(ju)(ju)部(bu)受力，造(zao)成局(ju)(ju)部(bu)的過拉伸，形(xing)成開裂、暗(an)裂等問題，一旦充(chong)填制冷劑，往(wang)往(wang)在(zai)此(ci)處發生制冷劑泄露。銅(tong)管(guan)穿過翅片后，要(yao)在(zai)漲(zhang)(zhang)管(guan)機上漲(zhang)(zhang)管(guan)，漲(zhang)(zhang)管(guan)的過程極易(yi)出現漲(zhang)(zhang)頭劃傷(shang)(shang)銅(tong)管(guan)，形(xing)成穿透傷(shang)(shang)造(zao)成銅(tong)管(guan)泄露；有(you)時(shi)由(you)于(yu)(yu)鋁箔內孔的毛刺過大，在(zai)漲(zhang)(zhang)管(guan)的時(shi)候毛刺刺透銅(tong)管(guan)造(zao)成泄露。

  3、銅(tong)管本(ben)身(shen)質量問題
  云(yun)南日立(li)中央空調銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)本身質(zhi)量(liang)的(de)原因可以分為(wei)外(wai)表(biao)(biao)(biao)面(mian)(mian)缺陷(xian)、內(nei)(nei)表(biao)(biao)(biao)面(mian)(mian)劃(hua)傷(shang)、內(nei)(nei)表(biao)(biao)(biao)面(mian)(mian)氧化等。銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)在(zai)漲(zhang)管(guan)(guan)、擴口(kou)的(de)冷加工變(bian)形中，表(biao)(biao)(biao)面(mian)(mian)受(shou)拉(la)應力(li)而伸長(chang)(chang)，當銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)外(wai)表(biao)(biao)(biao)面(mian)(mian)有深度傷(shang)痕時(shi)(shi)，銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)外(wai)表(biao)(biao)(biao)面(mian)(mian)承受(shou)不(bu)了表(biao)(biao)(biao)面(mian)(mian)拉(la)應力(li)，形成拉(la)斷現象，也就是我們看到的(de)銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)外(wai)表(biao)(biao)(biao)面(mian)(mian)開裂。銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)內(nei)(nei)表(biao)(biao)(biao)面(mian)(mian)有氧化時(shi)(shi)，在(zai)漲(zhang)管(guan)(guan)時(shi)(shi)由于氧化銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)內(nei)(nei)表(biao)(biao)(biao)面(mian)(mian)的(de)摩(mo)擦力(li)與沒(mei)有氧化銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)內(nei)(nei)表(biao)(biao)(biao)面(mian)(mian)的(de)摩(mo)擦力(li)不(bu)等，造(zao)成相同長(chang)(chang)度的(de)銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)下(xia)墩長(chang)(chang)度尺寸不(bu)一(yi)致，擴口(kou)時(shi)(shi)下(xia)墩量(liang)小的(de)銅(tong)(tong)(tong)(tong)(tong)管(guan)(guan)伸出長(chang)(chang)度長(chang)(chang)，造(zao)成擴口(kou)過大而開裂。

  4、焊(han)接(jie)方式的問(wen)題(ti)
  云(yun)南(nan)日(ri)立中央空調銅管在連接(jie)(jie)(jie)起來的過程中，需要用焊(han)料(liao)將分歧管與銅管焊(han)接(jie)(jie)(jie)在一起，焊(han)接(jie)(jie)(jie)方法分為充(chong)氮(dan)(dan)焊(han)接(jie)(jie)(jie)與不(bu)充(chong)氮(dan)(dan)焊(han)接(jie)(jie)(jie)兩(liang)種。一般(ban)會(hui)選(xuan)擇充(chong)氮(dan)(dan)焊(han)接(jie)(jie)(jie)，充(chong)氮(dan)(dan)焊(han)接(jie)(jie)(jie)可防止焊(han)口(kou)產(chan)生氧化(hua)物(wu)，經過長期(qi)的制冷劑系(xi)統循(xun)環，不(bu)充(chong)氮(dan)(dan)焊(han)接(jie)(jie)(jie)會(hui)導致焊(han)口(kou)氧化(hua)物(wu)脫落造成(cheng)管道(dao)臟(zang)堵，最后造成(cheng)壓縮機的損害。不(bu)但影響了制冷效果，嚴(yan)重(zhong)的還(huan)需要對壓縮機進行維修(xiu)或更換(huan)。

  以上四個方面就是日立中央空調銅管泄露的原因，當你家的日立中央空調不制冷時，很有可能就是銅管泄露了，此次你應該找澀澀免費網站:云南日立中央空調安裝公司為你維修。
