1、制冷(leng)系統:觀察風冷(leng)式(shi)冷(leng)水機制冷(leng)系統管(guan)(guan)(guan)路(lu)是(shi)(shi)(shi)否有(you)(you)(you)裂紋、破損、結(jie)霜、結(jie)露;檢(jian)查(cha)風冷(leng)冷(leng)水裝置的冷(leng)卻管(guan)(guan)(guan)路(lu)之間，以(yi)及管(guan)(guan)(guan)路(lu)與機殼之間，特別是(shi)(shi)(shi)制冷(leng)劑(ji)管(guan)(guan)(guan)路(lu)與風冷(leng)冷(leng)水機接(jie)頭(tou)(tou)的焊(han)接(jie)點處(chu)是(shi)(shi)(shi)否有(you)(you)(you)接(jie)觸和(he)摩擦。任何漏油都會有(you)(you)(you)油漬(zi)。也可以(yi)用(yong)干(gan)凈的軟(ruan)布和(he)紙對管(guan)(guan)(guan)道(dao)的焊(han)接(jie)和(he)接(jie)頭(tou)(tou)處(chu)進(jin)行擦洗，調查(cha)漏油情況，判(pan)斷是(shi)(shi)(shi)否有(you)(you)(you)漏油。

電(dian)源(yuan)(yuan)系統:檢查風冷(leng)(leng)式冷(leng)(leng)水機電(dian)源(yuan)(yuan)系統是(shi)否(fou)(fou)有(you)保(bao)險絲，電(dian)源(yuan)(yuan)線絕(jue)緣是(shi)否(fou)(fou)完(wan)好，電(dian)路板是(shi)否(fou)(fou)有(you)裂紋，連接處是(shi)否(fou)(fou)有(you)松動(dong)。特別是(shi)電(dian)氣連接沒(mei)有(you)從觸摸屏(ping)上(shang)伸出時，接線螺絲和插(cha)頭(tou)容易松動(dong)，導致(zhi)觸摸屏(ping)性(xing)能不佳。

冷水機

通風(feng)(feng)系統(tong):檢(jian)查空(kong)氣(qi)過濾網、熱交換器盤管、風(feng)(feng)冷式冷水機(ji)翅片(pian)是否(fou)積塵過多;進風(feng)(feng)口和出風(feng)(feng)口是否(fou)通暢;風(feng)(feng)機(ji)、葉片(pian)工(gong)作是否(fou)正常(chang)(chang);風(feng)(feng)量(liang)是否(fou)正常(chang)(chang);供水系統(tong)是否(fou)正常(chang)(chang)等。

水(shui)(shui)系(xi)統:檢查風(feng)冷(leng)式冷(leng)水(shui)(shui)機(ji)(ji)(ji)的(de)(de)水(shui)(shui)系(xi)統是否有(you)泄漏;進出口是否暢通;水(shui)(shui)泵運轉是否正常(chang)。仔細聽風(feng)冷(leng)式冷(leng)水(shui)(shui)機(ji)(ji)(ji)壓縮機(ji)(ji)(ji)開機(ji)(ji)(ji)、上電時(shi)的(de)(de)聲音，有(you)無異常(chang)聲音，風(feng)機(ji)(ji)(ji)、水(shui)(shui)泵工(gong)(gong)作時(shi)是否有(you)噪(zao)音，噪(zao)音是否過大(da)。風(feng)冷(leng)式冷(leng)水(shui)(shui)機(ji)(ji)(ji)工(gong)(gong)作時(shi)，振蕩一般(ban)較(jiao)弱，噪(zao)聲較(jiao)低。
