1. 電(dian)氣系統(tong):檢查風冷冷水(shui)機電(dian)氣系統(tong)保險絲是(shi)(shi)(shi)否(fou)(fou)吹斷，電(dian)氣導體絕緣是(shi)(shi)(shi)否(fou)(fou)完好，電(dian)路板是(shi)(shi)(shi)否(fou)(fou)開裂(lie)，接頭是(shi)(shi)(shi)否(fou)(fou)松動(dong)。特別(bie)是(shi)(shi)(shi)，如果電(dian)氣連接突出，接線螺絲和連接器(qi)容易松動(dong)，形成不(bu)良觸感。

2. 制(zhi)冷(leng)(leng)(leng)系(xi)統:檢查(cha)風(feng)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)水機(ji)制(zhi)冷(leng)(leng)(leng)系(xi)統各管路是否(fou)(fou)有(you)裂紋(wen)、損壞、結霜、結露現象;風(feng)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)水機(ji)制(zhi)冷(leng)(leng)(leng)管路之(zhi)間、管路與殼體之(zhi)間是否(fou)(fou)有(you)碰撞、摩擦(ca)，特別(bie)是制(zhi)冷(leng)(leng)(leng)劑管路的焊接(jie)點和風(feng)冷(leng)(leng)(leng)式冷(leng)(leng)(leng)水機(ji)接(jie)頭處(chu)(chu)是否(fou)(fou)有(you)泄(xie)漏。如果(guo)有(you)任何(he)泄(xie)漏，就會有(you)油漬(zi)。也可以用干凈的軟布(bu)和紙擦(ca)洗管道的焊點和連接(jie)處(chu)(chu)，并調查(cha)是否(fou)(fou)有(you)油漬(zi)，以確(que)定是否(fou)(fou)有(you)泄(xie)漏。

3.水(shui)(shui)系(xi)統:檢(jian)查(cha)風冷(leng)冷(leng)水(shui)(shui)機(ji)水(shui)(shui)系(xi)統是否(fou)漏水(shui)(shui);進、出水(shui)(shui)口是否(fou)暢通(tong);水(shui)(shui)泵是否(fou)正常工(gong)作。聽風冷(leng)冷(leng)水(shui)(shui)機(ji)組的壓縮機(ji)工(gong)作是否(fou)正常、異常，風機(ji)、水(shui)(shui)泵工(gong)作是否(fou)有噪(zao)音，噪(zao)音是否(fou)過(guo)大。風冷(leng)式冷(leng)水(shui)(shui)機(ji)組在運(yun)行過(guo)程中，正常情況下(xia)振動(dong)輕微，噪(zao)聲(sheng)小。

4. 通風(feng)(feng)系統:檢查風(feng)(feng)冷冷水機的空氣濾網、熱交換(huan)器盤管(guan)、翅片(pian)是否灰塵過多;進出風(feng)(feng)口是否暢通;風(feng)(feng)機、風(feng)(feng)機葉片(pian)工作是否正(zheng)(zheng)常;風(feng)(feng)力(li)是否正(zheng)(zheng)常，水系統是否正(zheng)(zheng)常。
