1、制冷(leng)(leng)系(xi)統:觀察風(feng)冷(leng)(leng)式冷(leng)(leng)水(shui)機制冷(leng)(leng)系(xi)統管路是否(fou)有(you)裂紋、破(po)損、結霜、結露;檢(jian)查風(feng)冷(leng)(leng)冷(leng)(leng)水(shui)裝置的冷(leng)(leng)卻管路之(zhi)間，以(yi)及(ji)管路與(yu)機殼之(zhi)間，特別是制冷(leng)(leng)劑管路與(yu)風(feng)冷(leng)(leng)冷(leng)(leng)水(shui)機接(jie)(jie)頭的焊接(jie)(jie)點處是否(fou)有(you)接(jie)(jie)觸和摩(mo)擦。任(ren)何漏油都會有(you)油漬(zi)。也可(ke)以(yi)用干凈的軟布和紙對(dui)管道的焊接(jie)(jie)和接(jie)(jie)頭處進行(xing)擦洗，調(diao)查漏油情況(kuang)，判斷(duan)是否(fou)有(you)漏油。

電(dian)源系(xi)統(tong):檢查風冷式冷水(shui)機電(dian)源系(xi)統(tong)是否有(you)保險絲(si)，電(dian)源線絕緣是否完好，電(dian)路板是否有(you)裂紋，連(lian)接(jie)處是否有(you)松(song)動。特別是電(dian)氣連(lian)接(jie)沒(mei)有(you)從觸摸屏(ping)上伸出時，接(jie)線螺絲(si)和(he)插頭容易松(song)動，導致觸摸屏(ping)性能不佳。

冷水機

通(tong)風系(xi)(xi)統:檢查空氣過(guo)濾網、熱交換器盤管、風冷式冷水機翅片是(shi)否(fou)(fou)積(ji)塵過(guo)多(duo);進風口(kou)(kou)和出(chu)風口(kou)(kou)是(shi)否(fou)(fou)通(tong)暢;風機、葉片工(gong)作是(shi)否(fou)(fou)正常;風量是(shi)否(fou)(fou)正常;供水系(xi)(xi)統是(shi)否(fou)(fou)正常等。

水(shui)系統(tong):檢(jian)查風(feng)(feng)(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)機(ji)(ji)的(de)水(shui)系統(tong)是(shi)否(fou)有(you)(you)泄漏;進(jin)出口(kou)是(shi)否(fou)暢通;水(shui)泵運轉是(shi)否(fou)正常。仔(zi)細聽(ting)風(feng)(feng)(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)機(ji)(ji)壓縮機(ji)(ji)開機(ji)(ji)、上(shang)電時(shi)的(de)聲(sheng)音(yin)，有(you)(you)無異(yi)常聲(sheng)音(yin)，風(feng)(feng)(feng)機(ji)(ji)、水(shui)泵工(gong)作時(shi)是(shi)否(fou)有(you)(you)噪(zao)音(yin)，噪(zao)音(yin)是(shi)否(fou)過大。風(feng)(feng)(feng)冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)機(ji)(ji)工(gong)作時(shi)，振(zhen)蕩一般較弱，噪(zao)聲(sheng)較低。
