1. 電(dian)氣(qi)系統:檢查風冷(leng)冷(leng)水機電(dian)氣(qi)系統保(bao)險絲是(shi)否吹(chui)斷，電(dian)氣(qi)導體絕緣是(shi)否完好，電(dian)路板(ban)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，接線(xian)螺絲和連接器(qi)容易松動(dong)，形成不(bu)良觸感。

2. 制(zhi)(zhi)冷(leng)(leng)系統:檢查(cha)風(feng)冷(leng)(leng)式冷(leng)(leng)水(shui)(shui)機制(zhi)(zhi)冷(leng)(leng)系統各管(guan)(guan)路是(shi)否有(you)(you)裂紋(wen)、損壞、結霜、結露現象;風(feng)冷(leng)(leng)式冷(leng)(leng)水(shui)(shui)機制(zhi)(zhi)冷(leng)(leng)管(guan)(guan)路之(zhi)間、管(guan)(guan)路與殼體之(zhi)間是(shi)否有(you)(you)碰撞、摩擦，特(te)別(bie)是(shi)制(zhi)(zhi)冷(leng)(leng)劑管(guan)(guan)路的(de)焊(han)(han)接(jie)點(dian)和風(feng)冷(leng)(leng)式冷(leng)(leng)水(shui)(shui)機接(jie)頭(tou)處(chu)是(shi)否有(you)(you)泄(xie)漏(lou)(lou)。如果有(you)(you)任(ren)何泄(xie)漏(lou)(lou)，就會有(you)(you)油漬。也可以用干凈的(de)軟(ruan)布(bu)和紙擦洗管(guan)(guan)道的(de)焊(han)(han)點(dian)和連接(jie)處(chu)，并調查(cha)是(shi)否有(you)(you)油漬，以確定是(shi)否有(you)(you)泄(xie)漏(lou)(lou)。

3.水(shui)(shui)(shui)系統(tong)(tong):檢查風冷(leng)冷(leng)水(shui)(shui)(shui)機水(shui)(shui)(shui)系統(tong)(tong)是(shi)否(fou)(fou)漏水(shui)(shui)(shui);進、出水(shui)(shui)(shui)口是(shi)否(fou)(fou)暢通;水(shui)(shui)(shui)泵是(shi)否(fou)(fou)正(zheng)常(chang)工作(zuo)(zuo)。聽(ting)風冷(leng)冷(leng)水(shui)(shui)(shui)機組(zu)的壓縮(suo)機工作(zuo)(zuo)是(shi)否(fou)(fou)正(zheng)常(chang)、異(yi)常(chang)，風機、水(shui)(shui)(shui)泵工作(zuo)(zuo)是(shi)否(fou)(fou)有噪(zao)音(yin)(yin)，噪(zao)音(yin)(yin)是(shi)否(fou)(fou)過(guo)大。風冷(leng)式冷(leng)水(shui)(shui)(shui)機組(zu)在運行過(guo)程中，正(zheng)常(chang)情況下振動輕微，噪(zao)聲小(xiao)。

4. 通風(feng)(feng)系統:檢查風(feng)(feng)冷(leng)冷(leng)水機(ji)的空氣濾網、熱(re)交換器(qi)盤管、翅片(pian)是(shi)(shi)否灰塵(chen)過多;進出風(feng)(feng)口是(shi)(shi)否暢通;風(feng)(feng)機(ji)、風(feng)(feng)機(ji)葉片(pian)工作(zuo)是(shi)(shi)否正常(chang);風(feng)(feng)力是(shi)(shi)否正常(chang)，水系統是(shi)(shi)否正常(chang)。
