1. 電(dian)(dian)氣(qi)系統:檢查風冷(leng)冷(leng)水(shui)機電(dian)(dian)氣(qi)系統保(bao)險絲是(shi)(shi)否吹(chui)斷，電(dian)(dian)氣(qi)導體絕緣(yuan)是(shi)(shi)否完好，電(dian)(dian)路板是(shi)(shi)否開(kai)裂，接頭是(shi)(shi)否松動。特別是(shi)(shi)，如(ru)果電(dian)(dian)氣(qi)連接突(tu)出，接線螺(luo)絲和連接器容易松動，形成不良觸感。

2. 制(zhi)冷(leng)(leng)(leng)(leng)系統:檢查(cha)風冷(leng)(leng)(leng)(leng)式(shi)冷(leng)(leng)(leng)(leng)水機(ji)制(zhi)冷(leng)(leng)(leng)(leng)系統各管(guan)路是(shi)否有(you)裂紋、損壞、結霜(shuang)、結露現象;風冷(leng)(leng)(leng)(leng)式(shi)冷(leng)(leng)(leng)(leng)水機(ji)制(zhi)冷(leng)(leng)(leng)(leng)管(guan)路之(zhi)間、管(guan)路與(yu)殼(ke)體之(zhi)間是(shi)否有(you)碰撞(zhuang)、摩擦(ca)，特別是(shi)制(zhi)冷(leng)(leng)(leng)(leng)劑管(guan)路的(de)焊接點(dian)和(he)風冷(leng)(leng)(leng)(leng)式(shi)冷(leng)(leng)(leng)(leng)水機(ji)接頭處(chu)是(shi)否有(you)泄漏。如果有(you)任何泄漏，就會有(you)油(you)漬。也可以用干凈的(de)軟布和(he)紙(zhi)擦(ca)洗(xi)管(guan)道的(de)焊點(dian)和(he)連接處(chu)，并調(diao)查(cha)是(shi)否有(you)油(you)漬，以確定是(shi)否有(you)泄漏。

3.水(shui)(shui)(shui)系統:檢查風(feng)冷(leng)(leng)冷(leng)(leng)水(shui)(shui)(shui)機水(shui)(shui)(shui)系統是否(fou)(fou)(fou)漏水(shui)(shui)(shui);進、出水(shui)(shui)(shui)口是否(fou)(fou)(fou)暢通;水(shui)(shui)(shui)泵(beng)是否(fou)(fou)(fou)正(zheng)常(chang)工(gong)作(zuo)(zuo)。聽(ting)風(feng)冷(leng)(leng)冷(leng)(leng)水(shui)(shui)(shui)機組(zu)的壓縮機工(gong)作(zuo)(zuo)是否(fou)(fou)(fou)正(zheng)常(chang)、異常(chang)，風(feng)機、水(shui)(shui)(shui)泵(beng)工(gong)作(zuo)(zuo)是否(fou)(fou)(fou)有噪(zao)音，噪(zao)音是否(fou)(fou)(fou)過大。風(feng)冷(leng)(leng)式冷(leng)(leng)水(shui)(shui)(shui)機組(zu)在(zai)運行過程中，正(zheng)常(chang)情況下振動(dong)輕微，噪(zao)聲小。

4. 通風(feng)(feng)系統:檢查風(feng)(feng)冷(leng)冷(leng)水機(ji)的空氣濾(lv)網、熱交換器盤(pan)管、翅片是否灰(hui)塵(chen)過多;進出風(feng)(feng)口是否暢(chang)通;風(feng)(feng)機(ji)、風(feng)(feng)機(ji)葉片工作是否正(zheng)常;風(feng)(feng)力是否正(zheng)常，水系統是否正(zheng)常。
