1. 電(dian)氣(qi)系統(tong):檢查風冷(leng)冷(leng)水(shui)機電(dian)氣(qi)系統(tong)保險絲(si)是(shi)否吹(chui)斷，電(dian)氣(qi)導(dao)體絕(jue)緣是(shi)否完好，電(dian)路板是(shi)否開裂，接頭是(shi)否松動(dong)。特別(bie)是(shi)，如果電(dian)氣(qi)連接突出(chu)，接線螺絲(si)和(he)連接器容易松動(dong)，形成不(bu)良觸感。

2. 制(zhi)(zhi)冷系(xi)統:檢查(cha)風冷式冷水機制(zhi)(zhi)冷系(xi)統各(ge)管(guan)路是(shi)(shi)(shi)否(fou)有(you)(you)(you)裂紋、損壞、結霜、結露(lu)現象;風冷式冷水機制(zhi)(zhi)冷管(guan)路之間(jian)、管(guan)路與殼體之間(jian)是(shi)(shi)(shi)否(fou)有(you)(you)(you)碰撞、摩(mo)擦，特別是(shi)(shi)(shi)制(zhi)(zhi)冷劑管(guan)路的(de)焊接點(dian)和風冷式冷水機接頭處是(shi)(shi)(shi)否(fou)有(you)(you)(you)泄漏。如果(guo)有(you)(you)(you)任何泄漏，就會有(you)(you)(you)油(you)(you)漬。也可以用干凈(jing)的(de)軟布和紙擦洗管(guan)道(dao)的(de)焊點(dian)和連接處，并(bing)調查(cha)是(shi)(shi)(shi)否(fou)有(you)(you)(you)油(you)(you)漬，以確定是(shi)(shi)(shi)否(fou)有(you)(you)(you)泄漏。

3.水(shui)系統(tong):檢查風(feng)冷冷水(shui)機水(shui)系統(tong)是否(fou)(fou)漏水(shui);進(jin)、出水(shui)口(kou)是否(fou)(fou)暢通;水(shui)泵是否(fou)(fou)正常(chang)工(gong)作。聽風(feng)冷冷水(shui)機組(zu)的壓縮機工(gong)作是否(fou)(fou)正常(chang)、異常(chang)，風(feng)機、水(shui)泵工(gong)作是否(fou)(fou)有(you)噪(zao)音，噪(zao)音是否(fou)(fou)過(guo)大。風(feng)冷式冷水(shui)機組(zu)在(zai)運(yun)行(xing)過(guo)程(cheng)中，正常(chang)情況下振動輕微(wei)，噪(zao)聲(sheng)小。

4. 通(tong)(tong)風(feng)(feng)系統(tong):檢(jian)查(cha)風(feng)(feng)冷冷水(shui)機(ji)的空氣濾網(wang)、熱交(jiao)換(huan)器(qi)盤管、翅(chi)片是否(fou)(fou)灰塵過多;進出風(feng)(feng)口(kou)是否(fou)(fou)暢(chang)通(tong)(tong);風(feng)(feng)機(ji)、風(feng)(feng)機(ji)葉(xie)片工作是否(fou)(fou)正常;風(feng)(feng)力(li)是否(fou)(fou)正常，水(shui)系統(tong)是否(fou)(fou)正常。
