1. 電氣(qi)(qi)系(xi)(xi)統:檢查(cha)風冷冷水機電氣(qi)(qi)系(xi)(xi)統保(bao)險絲(si)是(shi)否(fou)吹(chui)斷，電氣(qi)(qi)導體絕緣是(shi)否(fou)完(wan)好，電路板是(shi)否(fou)開裂，接(jie)頭(tou)是(shi)否(fou)松動(dong)。特別是(shi)，如果電氣(qi)(qi)連接(jie)突出，接(jie)線螺絲(si)和連接(jie)器容易松動(dong)，形成不良觸感(gan)。

2. 制(zhi)(zhi)冷(leng)系統(tong):檢查(cha)(cha)風冷(leng)式冷(leng)水機制(zhi)(zhi)冷(leng)系統(tong)各(ge)管(guan)路是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)有(you)(you)(you)(you)裂紋、損壞、結(jie)霜、結(jie)露現象;風冷(leng)式冷(leng)水機制(zhi)(zhi)冷(leng)管(guan)路之間、管(guan)路與殼(ke)體之間是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)有(you)(you)(you)(you)碰撞(zhuang)、摩擦(ca)(ca)，特(te)別是(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)劑(ji)管(guan)路的焊接點(dian)和(he)風冷(leng)式冷(leng)水機接頭處是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)有(you)(you)(you)(you)泄漏。如果有(you)(you)(you)(you)任何泄漏，就會(hui)有(you)(you)(you)(you)油(you)漬(zi)。也可以用干(gan)凈的軟(ruan)布和(he)紙擦(ca)(ca)洗管(guan)道的焊點(dian)和(he)連接處，并調查(cha)(cha)是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)有(you)(you)(you)(you)油(you)漬(zi)，以確定是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)有(you)(you)(you)(you)泄漏。

3.水(shui)系統:檢查風(feng)冷(leng)(leng)冷(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)水(shui)系統是否(fou)(fou)(fou)漏水(shui);進(jin)、出(chu)水(shui)口(kou)是否(fou)(fou)(fou)暢(chang)通;水(shui)泵是否(fou)(fou)(fou)正常工(gong)作。聽風(feng)冷(leng)(leng)冷(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)組的壓(ya)縮(suo)機(ji)(ji)(ji)(ji)工(gong)作是否(fou)(fou)(fou)正常、異常，風(feng)機(ji)(ji)(ji)(ji)、水(shui)泵工(gong)作是否(fou)(fou)(fou)有噪音，噪音是否(fou)(fou)(fou)過大(da)。風(feng)冷(leng)(leng)式冷(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)組在運行(xing)過程中，正常情況下振動(dong)輕微，噪聲小。

4. 通(tong)(tong)風(feng)系(xi)統:檢查風(feng)冷冷水機(ji)的空氣濾網、熱交換(huan)器盤管、翅(chi)片(pian)是(shi)否(fou)灰塵過多(duo);進(jin)出風(feng)口(kou)是(shi)否(fou)暢通(tong)(tong);風(feng)機(ji)、風(feng)機(ji)葉片(pian)工作是(shi)否(fou)正(zheng)常;風(feng)力是(shi)否(fou)正(zheng)常，水系(xi)統是(shi)否(fou)正(zheng)常。
