1、制冷(leng)(leng)(leng)系統:觀察風冷(leng)(leng)(leng)式(shi)冷(leng)(leng)(leng)水機制冷(leng)(leng)(leng)系統管(guan)路(lu)是(shi)否有裂紋、破(po)損(sun)、結霜、結露;檢查(cha)風冷(leng)(leng)(leng)冷(leng)(leng)(leng)水裝置的(de)冷(leng)(leng)(leng)卻(que)管(guan)路(lu)之間(jian)，以(yi)及管(guan)路(lu)與機殼之間(jian)，特(te)別是(shi)制冷(leng)(leng)(leng)劑管(guan)路(lu)與風冷(leng)(leng)(leng)冷(leng)(leng)(leng)水機接(jie)頭(tou)的(de)焊接(jie)點處是(shi)否有接(jie)觸和(he)摩擦。任何漏(lou)油(you)都會(hui)有油(you)漬。也可以(yi)用(yong)干凈的(de)軟布和(he)紙對(dui)管(guan)道的(de)焊接(jie)和(he)接(jie)頭(tou)處進(jin)行(xing)擦洗(xi)，調查(cha)漏(lou)油(you)情(qing)況，判斷是(shi)否有漏(lou)油(you)。

電(dian)(dian)(dian)源(yuan)系統:檢(jian)查風冷(leng)(leng)式冷(leng)(leng)水機(ji)電(dian)(dian)(dian)源(yuan)系統是否(fou)有(you)保險(xian)絲，電(dian)(dian)(dian)源(yuan)線絕緣是否(fou)完好，電(dian)(dian)(dian)路板是否(fou)有(you)裂紋，連接(jie)處是否(fou)有(you)松(song)(song)動。特別(bie)是電(dian)(dian)(dian)氣連接(jie)沒有(you)從(cong)觸摸(mo)屏上伸(shen)出(chu)時，接(jie)線螺(luo)絲和插頭容(rong)易松(song)(song)動，導致(zhi)觸摸(mo)屏性能不佳(jia)。

冷水機

通風(feng)系統:檢查(cha)空(kong)氣過濾網、熱交換器(qi)盤(pan)管(guan)、風(feng)冷式冷水(shui)(shui)機(ji)(ji)翅片(pian)是(shi)否(fou)積塵過多;進風(feng)口(kou)和(he)出風(feng)口(kou)是(shi)否(fou)通暢;風(feng)機(ji)(ji)、葉片(pian)工作是(shi)否(fou)正常(chang);風(feng)量(liang)是(shi)否(fou)正常(chang);供水(shui)(shui)系統是(shi)否(fou)正常(chang)等(deng)。

水系統:檢查風(feng)(feng)(feng)冷(leng)式冷(leng)水機(ji)(ji)的水系統是(shi)(shi)否(fou)有(you)泄漏;進出(chu)口是(shi)(shi)否(fou)暢通(tong);水泵(beng)(beng)運轉是(shi)(shi)否(fou)正常。仔細聽風(feng)(feng)(feng)冷(leng)式冷(leng)水機(ji)(ji)壓縮機(ji)(ji)開機(ji)(ji)、上電(dian)時(shi)的聲(sheng)音，有(you)無異常聲(sheng)音，風(feng)(feng)(feng)機(ji)(ji)、水泵(beng)(beng)工作(zuo)時(shi)是(shi)(shi)否(fou)有(you)噪(zao)音，噪(zao)音是(shi)(shi)否(fou)過大。風(feng)(feng)(feng)冷(leng)式冷(leng)水機(ji)(ji)工作(zuo)時(shi)，振蕩一般較弱，噪(zao)聲(sheng)較低。
