1. 電(dian)氣(qi)系統:檢查(cha)風(feng)冷冷水機電(dian)氣(qi)系統保險(xian)絲(si)是(shi)否(fou)吹(chui)斷，電(dian)氣(qi)導體絕(jue)緣是(shi)否(fou)完好(hao)，電(dian)路(lu)板是(shi)否(fou)開裂，接(jie)頭(tou)是(shi)否(fou)松(song)動。特別是(shi)，如果(guo)電(dian)氣(qi)連(lian)接(jie)突出，接(jie)線(xian)螺(luo)絲(si)和(he)連(lian)接(jie)器容易松(song)動，形成不良觸感。

2. 制(zhi)冷(leng)(leng)系統(tong):檢查風冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)機制(zhi)冷(leng)(leng)系統(tong)各(ge)管(guan)路是(shi)否(fou)(fou)有(you)裂(lie)紋、損壞、結霜(shuang)、結露現象;風冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)機制(zhi)冷(leng)(leng)管(guan)路之(zhi)間、管(guan)路與殼體之(zhi)間是(shi)否(fou)(fou)有(you)碰撞、摩擦(ca)，特別(bie)是(shi)制(zhi)冷(leng)(leng)劑管(guan)路的(de)焊接點(dian)和(he)風冷(leng)(leng)式(shi)冷(leng)(leng)水(shui)機接頭處是(shi)否(fou)(fou)有(you)泄漏(lou)(lou)。如果(guo)有(you)任何泄漏(lou)(lou)，就(jiu)會有(you)油(you)漬。也可以用干凈的(de)軟布和(he)紙擦(ca)洗管(guan)道的(de)焊點(dian)和(he)連(lian)接處，并(bing)調(diao)查是(shi)否(fou)(fou)有(you)油(you)漬，以確定是(shi)否(fou)(fou)有(you)泄漏(lou)(lou)。

3.水(shui)(shui)系統(tong):檢查風冷(leng)冷(leng)水(shui)(shui)機(ji)(ji)水(shui)(shui)系統(tong)是(shi)否(fou)漏水(shui)(shui);進、出(chu)水(shui)(shui)口是(shi)否(fou)暢通;水(shui)(shui)泵(beng)是(shi)否(fou)正常(chang)工作(zuo)。聽風冷(leng)冷(leng)水(shui)(shui)機(ji)(ji)組的壓(ya)縮機(ji)(ji)工作(zuo)是(shi)否(fou)正常(chang)、異(yi)常(chang)，風機(ji)(ji)、水(shui)(shui)泵(beng)工作(zuo)是(shi)否(fou)有噪音，噪音是(shi)否(fou)過大。風冷(leng)式冷(leng)水(shui)(shui)機(ji)(ji)組在(zai)運(yun)行(xing)過程中(zhong)，正常(chang)情況下振動輕微(wei)，噪聲小(xiao)。

4. 通(tong)風(feng)系統:檢(jian)查風(feng)冷(leng)(leng)冷(leng)(leng)水機的(de)空氣濾網、熱交換(huan)器盤管、翅片(pian)是(shi)(shi)否(fou)(fou)(fou)灰塵過多(duo);進出風(feng)口是(shi)(shi)否(fou)(fou)(fou)暢通(tong);風(feng)機、風(feng)機葉片(pian)工作是(shi)(shi)否(fou)(fou)(fou)正(zheng)常;風(feng)力是(shi)(shi)否(fou)(fou)(fou)正(zheng)常，水系統是(shi)(shi)否(fou)(fou)(fou)正(zheng)常。
