威海中央空調中變頻空調的維修機巧

威海中央空調中變頻空調的維修技(ji)巧(qiao)
　　變頻空(kong)調(diao)(diao)故(gu)(gu)障可分(fen)兩(liang)大類：一類是(shi)(shi)空(kong)調(diao)(diao)外(wai)部(bu)因素(su)導(dao)致(zhi)不(bu)是(shi)(shi)故(gu)(gu)障的(de)(de)故(gu)(gu)障；另一類是(shi)(shi)空(kong)調(diao)(diao)自(zi)身(shen)故(gu)(gu)障。因此在分(fen)析處理變頻空(kong)調(diao)(diao)故(gu)(gu)障時，首先要(yao)考慮排除空(kong)調(diao)(diao)的(de)(de)外(wai)部(bu)故(gu)(gu)障，比如：用戶的(de)(de)是(shi)(shi)否(fou)過(guo)高或過(guo)低；電源線路是(shi)(shi)否(fou)存(cun)在接觸不(bu)良；電源線是(shi)(shi)否(fou)存(cun)在容量不(bu)足；空(kong)調(diao)(diao)的(de)(de)安裝位置是(shi)(shi)否(fou)靠西曬；外(wai)機排風口有無雜物遮擋或不(bu)暢通；功能設置是(shi)(shi)否(fou)正(zheng)確等。在排除空(kong)調(diao)(diao)外(wai)部(bu)因素(su)后，再考慮空(kong)調(diao)(diao)的(de)(de)自(zi)身(shen)故(gu)(gu)障。
　　在(zai)檢(jian)查過(guo)程中(zhong)．要分析是制(zhi)冷(leng)(leng)系(xi)(xi)統(tong)(tong)故障(zhang)還是電氣(qi)(qi)系(xi)(xi)統(tong)(tong)故障(zhang)，通常(chang)在(zai)這兩類故障(zhang)中(zhong)，先要判斷或(huo)檢(jian)測制(zhi)冷(leng)(leng)系(xi)(xi)統(tong)(tong)是否存在(zai)漏制(zhi)冷(leng)(leng)劑，缺少(shao)制(zhi)冷(leng)(leng)劑或(huo)制(zhi)冷(leng)(leng)劑過(guo)量(liang)；制(zhi)冷(leng)(leng)系(xi)(xi)統(tong)(tong)是否存在(zai)管路(lu)堵塞，冷(leng)(leng)凝器散熱不良(liang)或(huo)通風(feng)不暢(chang)；四通問和(he)電子膨(peng)脹閥是否存在(zai)關(guan)閉不嚴、串氣(qi)(qi)或(huo)開(kai)度(du)有問題等。
　　通過(guo)排除(chu)這些一(yi)般性的故(gu)(gu)障(zhang)(zhang)(zhang)后，然后再考(kao)(kao)(kao)(kao)慮(lv)排除(chu)電(dian)(dian)(dian)氣(qi)系統(tong)故(gu)(gu)障(zhang)(zhang)(zhang)，電(dian)(dian)(dian)氣(qi)系統(tong)故(gu)(gu)障(zhang)(zhang)(zhang)一(yi)般較為(wei)復雜，通常先要(yao)考(kao)(kao)(kao)(kao)慮(lv)排除(chu)電(dian)(dian)(dian)源故(gu)(gu)障(zhang)(zhang)(zhang)，包(bao)括室(shi)內機和室(shi)外機電(dian)(dian)(dian)源，特別是采用開關電(dian)(dian)(dian)源的電(dian)(dian)(dian)路(lu)(lu)(lu)；再考(kao)(kao)(kao)(kao)慮(lv)排除(chu)電(dian)(dian)(dian)控(kong)部分故(gu)(gu)障(zhang)(zhang)(zhang)，比(bi)如(ru)：和風機故(gu)(gu)障(zhang)(zhang)(zhang)；繼(ji)電(dian)(dian)(dian)器或(huo)(huo)雙向(xiang)可控(kong)硅是否存在接觸(chu)不(bu)良、開路(lu)(lu)(lu)或(huo)(huo)短路(lu)(lu)(lu)；后考(kao)(kao)(kao)(kao)慮(lv)排除(chu)電(dian)(dian)(dian)路(lu)(lu)(lu)故(gu)(gu)障(zhang)(zhang)(zhang)，比(bi)如(ru)：判斷(duan)或(huo)(huo)檢(jian)測(ce)主控(kong)電(dian)(dian)(dian)路(lu)(lu)(lu)、晶振電(dian)(dian)(dian)路(lu)(lu)(lu)、復位電(dian)(dian)(dian)路(lu)(lu)(lu)、驅動電(dian)(dian)(dian)路(lu)(lu)(lu)、電(dian)(dian)(dian)壓(ya)檢(jian)測(ce)電(dian)(dian)(dian)路(lu)(lu)(lu)、電(dian)(dian)(dian)流檢(jian)測(ce)電(dian)(dian)(dian)路(lu)(lu)(lu)及電(dian)(dian)(dian)路(lu)(lu)(lu)等。綜合考(kao)(kao)(kao)(kao)慮(lv)縮小故(gu)(gu)障(zhang)(zhang)(zhang)范圍，加速(su)查找(zhao)故(gu)(gu)障(zhang)(zhang)(zhang)部位和原因。
