1、制冷(leng)(leng)(leng)(leng)系(xi)統(tong):觀察風(feng)冷(leng)(leng)(leng)(leng)式冷(leng)(leng)(leng)(leng)水(shui)(shui)機(ji)制冷(leng)(leng)(leng)(leng)系(xi)統(tong)管(guan)(guan)(guan)路是(shi)(shi)否(fou)有裂紋、破損、結霜、結露(lu);檢(jian)查風(feng)冷(leng)(leng)(leng)(leng)冷(leng)(leng)(leng)(leng)水(shui)(shui)裝(zhuang)置的(de)冷(leng)(leng)(leng)(leng)卻管(guan)(guan)(guan)路之間，以(yi)及管(guan)(guan)(guan)路與機(ji)殼之間，特(te)別是(shi)(shi)制冷(leng)(leng)(leng)(leng)劑管(guan)(guan)(guan)路與風(feng)冷(leng)(leng)(leng)(leng)冷(leng)(leng)(leng)(leng)水(shui)(shui)機(ji)接(jie)頭的(de)焊接(jie)點處(chu)(chu)是(shi)(shi)否(fou)有接(jie)觸和摩擦(ca)(ca)。任何漏油都會有油漬。也可(ke)以(yi)用干凈的(de)軟布(bu)和紙對管(guan)(guan)(guan)道的(de)焊接(jie)和接(jie)頭處(chu)(chu)進行擦(ca)(ca)洗，調查漏油情況(kuang)，判斷是(shi)(shi)否(fou)有漏油。

電源系統(tong):檢(jian)查風冷式(shi)冷水(shui)機(ji)電源系統(tong)是(shi)否有(you)保險絲，電源線絕緣(yuan)是(shi)否完好，電路板是(shi)否有(you)裂紋，連(lian)接處是(shi)否有(you)松動。特別是(shi)電氣連(lian)接沒有(you)從(cong)觸摸屏上伸出時，接線螺絲和插(cha)頭容(rong)易(yi)松動，導(dao)致觸摸屏性(xing)能不(bu)佳。

冷水機

通風(feng)系統:檢查空氣過濾網、熱交換器(qi)盤(pan)管、風(feng)冷式冷水機翅片是(shi)否(fou)積塵過多;進(jin)風(feng)口和(he)出風(feng)口是(shi)否(fou)通暢(chang);風(feng)機、葉片工作是(shi)否(fou)正常;風(feng)量是(shi)否(fou)正常;供(gong)水系統是(shi)否(fou)正常等。

水(shui)(shui)系(xi)統:檢查(cha)風(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)(shui)機的(de)水(shui)(shui)系(xi)統是否(fou)(fou)有(you)泄漏;進(jin)出口(kou)是否(fou)(fou)暢通;水(shui)(shui)泵運轉是否(fou)(fou)正常。仔細聽風(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)(shui)機壓縮機開(kai)機、上電(dian)時(shi)的(de)聲(sheng)音(yin)，有(you)無(wu)異常聲(sheng)音(yin)，風(feng)機、水(shui)(shui)泵工(gong)作時(shi)是否(fou)(fou)有(you)噪音(yin)，噪音(yin)是否(fou)(fou)過大。風(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)(shui)機工(gong)作時(shi)，振蕩一般(ban)較弱，噪聲(sheng)較低。
