威海中央空調中變頻空調的維修機巧

威海中(zhong)央空調中(zhong)變頻空調的(de)維修技(ji)巧
　　變(bian)頻空(kong)調故(gu)(gu)障(zhang)(zhang)可分兩大類(lei)：一(yi)類(lei)是空(kong)調外(wai)(wai)部因(yin)素(su)導(dao)致(zhi)不(bu)是故(gu)(gu)障(zhang)(zhang)的故(gu)(gu)障(zhang)(zhang)；另一(yi)類(lei)是空(kong)調自(zi)身故(gu)(gu)障(zhang)(zhang)。因(yin)此在(zai)分析處(chu)理變(bian)頻空(kong)調故(gu)(gu)障(zhang)(zhang)時，首(shou)先要考慮(lv)排(pai)(pai)除空(kong)調的外(wai)(wai)部故(gu)(gu)障(zhang)(zhang)，比如：用(yong)戶的是否(fou)過高或過低；電源(yuan)線路是否(fou)存在(zai)接觸不(bu)良(liang)；電源(yuan)線是否(fou)存在(zai)容量不(bu)足；空(kong)調的安裝位置是否(fou)靠西曬；外(wai)(wai)機排(pai)(pai)風口有無雜物遮擋或不(bu)暢通(tong)；功能設置是否(fou)正確等。在(zai)排(pai)(pai)除空(kong)調外(wai)(wai)部因(yin)素(su)后，再(zai)考慮(lv)空(kong)調的自(zi)身故(gu)(gu)障(zhang)(zhang)。
　　在檢(jian)查(cha)過程中．要分析是(shi)制(zhi)(zhi)冷(leng)系(xi)統(tong)故障(zhang)還(huan)是(shi)電氣系(xi)統(tong)故障(zhang)，通(tong)常在這兩類故障(zhang)中，先要判斷或檢(jian)測制(zhi)(zhi)冷(leng)系(xi)統(tong)是(shi)否(fou)存在漏(lou)制(zhi)(zhi)冷(leng)劑(ji)，缺少制(zhi)(zhi)冷(leng)劑(ji)或制(zhi)(zhi)冷(leng)劑(ji)過量；制(zhi)(zhi)冷(leng)系(xi)統(tong)是(shi)否(fou)存在管路堵(du)塞，冷(leng)凝器散熱不(bu)(bu)良或通(tong)風不(bu)(bu)暢(chang)；四通(tong)問和電子膨脹閥是(shi)否(fou)存在關(guan)閉不(bu)(bu)嚴(yan)、串氣或開度有(you)問題等。
　　通過排(pai)(pai)除(chu)(chu)這(zhe)些一(yi)般(ban)性的(de)故(gu)(gu)障(zhang)(zhang)(zhang)后(hou)，然后(hou)再考(kao)慮(lv)排(pai)(pai)除(chu)(chu)電(dian)(dian)(dian)氣系統故(gu)(gu)障(zhang)(zhang)(zhang)，電(dian)(dian)(dian)氣系統故(gu)(gu)障(zhang)(zhang)(zhang)一(yi)般(ban)較為復雜，通常先要考(kao)慮(lv)排(pai)(pai)除(chu)(chu)電(dian)(dian)(dian)源故(gu)(gu)障(zhang)(zhang)(zhang)，包括(kuo)室內機和(he)室外機電(dian)(dian)(dian)源，特(te)別是采用開(kai)關電(dian)(dian)(dian)源的(de)電(dian)(dian)(dian)路(lu)(lu)(lu)；再考(kao)慮(lv)排(pai)(pai)除(chu)(chu)電(dian)(dian)(dian)控部分故(gu)(gu)障(zhang)(zhang)(zhang)，比如(ru)：和(he)風機故(gu)(gu)障(zhang)(zhang)(zhang)；繼電(dian)(dian)(dian)器或(huo)雙向(xiang)可控硅是否存在接觸(chu)不(bu)良(liang)、開(kai)路(lu)(lu)(lu)或(huo)短路(lu)(lu)(lu)；后(hou)考(kao)慮(lv)排(pai)(pai)除(chu)(chu)電(dian)(dian)(dian)路(lu)(lu)(lu)故(gu)(gu)障(zhang)(zhang)(zhang)，比如(ru)：判斷或(huo)檢(jian)測(ce)(ce)(ce)主控電(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(dong)電(dian)(dian)(dian)路(lu)(lu)(lu)、電(dian)(dian)(dian)壓檢(jian)測(ce)(ce)(ce)電(dian)(dian)(dian)路(lu)(lu)(lu)、電(dian)(dian)(dian)流檢(jian)測(ce)(ce)(ce)電(dian)(dian)(dian)路(lu)(lu)(lu)及電(dian)(dian)(dian)路(lu)(lu)(lu)等。綜合考(kao)慮(lv)縮小故(gu)(gu)障(zhang)(zhang)(zhang)范(fan)圍，加速查找故(gu)(gu)障(zhang)(zhang)(zhang)部位和(he)原因。
