1、制冷(leng)(leng)(leng)(leng)系(xi)統(tong):觀察風(feng)(feng)冷(leng)(leng)(leng)(leng)式(shi)冷(leng)(leng)(leng)(leng)水機制冷(leng)(leng)(leng)(leng)系(xi)統(tong)管路是否有(you)(you)裂紋、破損、結(jie)霜、結(jie)露;檢(jian)查(cha)風(feng)(feng)冷(leng)(leng)(leng)(leng)冷(leng)(leng)(leng)(leng)水裝置(zhi)的冷(leng)(leng)(leng)(leng)卻管路之間，以(yi)及管路與機殼之間，特別是制冷(leng)(leng)(leng)(leng)劑管路與風(feng)(feng)冷(leng)(leng)(leng)(leng)冷(leng)(leng)(leng)(leng)水機接(jie)(jie)頭的焊(han)接(jie)(jie)點處(chu)是否有(you)(you)接(jie)(jie)觸和(he)摩擦(ca)。任何(he)漏油都會有(you)(you)油漬(zi)。也可以(yi)用干凈(jing)的軟布和(he)紙對(dui)管道的焊(han)接(jie)(jie)和(he)接(jie)(jie)頭處(chu)進行擦(ca)洗，調(diao)查(cha)漏油情況，判斷是否有(you)(you)漏油。

電源(yuan)系統(tong):檢查風(feng)冷式冷水機(ji)電源(yuan)系統(tong)是(shi)(shi)否(fou)有(you)保險絲，電源(yuan)線絕緣是(shi)(shi)否(fou)完(wan)好(hao)，電路板(ban)是(shi)(shi)否(fou)有(you)裂紋(wen)，連接(jie)處是(shi)(shi)否(fou)有(you)松動(dong)。特別(bie)是(shi)(shi)電氣連接(jie)沒(mei)有(you)從(cong)觸摸屏上伸出時，接(jie)線螺絲和插頭容易(yi)松動(dong)，導致(zhi)觸摸屏性能(neng)不佳(jia)。

冷水機

通風系(xi)統:檢(jian)查空(kong)氣過濾網、熱交換器盤(pan)管、風冷(leng)式冷(leng)水機翅片(pian)是(shi)否(fou)(fou)積塵過多(duo);進風口(kou)和(he)出風口(kou)是(shi)否(fou)(fou)通暢;風機、葉片(pian)工作是(shi)否(fou)(fou)正(zheng)常;風量是(shi)否(fou)(fou)正(zheng)常;供水系(xi)統是(shi)否(fou)(fou)正(zheng)常等。

水(shui)系(xi)統:檢查風冷(leng)(leng)(leng)式(shi)(shi)冷(leng)(leng)(leng)水(shui)機(ji)的水(shui)系(xi)統是(shi)否有(you)泄漏;進出口是(shi)否暢通;水(shui)泵運轉是(shi)否正常。仔細聽風冷(leng)(leng)(leng)式(shi)(shi)冷(leng)(leng)(leng)水(shui)機(ji)壓縮(suo)機(ji)開機(ji)、上電時的聲(sheng)音，有(you)無異常聲(sheng)音，風機(ji)、水(shui)泵工(gong)作時是(shi)否有(you)噪(zao)音，噪(zao)音是(shi)否過大(da)。風冷(leng)(leng)(leng)式(shi)(shi)冷(leng)(leng)(leng)水(shui)機(ji)工(gong)作時，振蕩一般較弱，噪(zao)聲(sheng)較低。
