1. 電(dian)氣(qi)系統(tong):檢查(cha)風冷(leng)冷(leng)水機(ji)電(dian)氣(qi)系統(tong)保險絲是(shi)(shi)否吹斷(duan)，電(dian)氣(qi)導體(ti)絕緣(yuan)是(shi)(shi)否完好，電(dian)路板是(shi)(shi)否開裂，接頭是(shi)(shi)否松(song)動(dong)。特別(bie)是(shi)(shi)，如果電(dian)氣(qi)連(lian)接突(tu)出，接線(xian)螺絲和連(lian)接器容易松(song)動(dong)，形(xing)成不良觸感。

2. 制冷(leng)系(xi)統:檢查風(feng)冷(leng)式(shi)冷(leng)水機(ji)制冷(leng)系(xi)統各(ge)管(guan)路(lu)是(shi)否(fou)(fou)有(you)裂紋、損壞、結霜、結露(lu)現象;風(feng)冷(leng)式(shi)冷(leng)水機(ji)制冷(leng)管(guan)路(lu)之間、管(guan)路(lu)與殼體之間是(shi)否(fou)(fou)有(you)碰撞、摩擦(ca)，特別是(shi)制冷(leng)劑管(guan)路(lu)的(de)焊接點和風(feng)冷(leng)式(shi)冷(leng)水機(ji)接頭處是(shi)否(fou)(fou)有(you)泄漏。如果有(you)任(ren)何泄漏，就(jiu)會有(you)油漬。也可以用干凈的(de)軟(ruan)布和紙擦(ca)洗(xi)管(guan)道(dao)的(de)焊點和連(lian)接處，并調查是(shi)否(fou)(fou)有(you)油漬，以確(que)定(ding)是(shi)否(fou)(fou)有(you)泄漏。

3.水(shui)(shui)(shui)系統:檢查風(feng)冷(leng)冷(leng)水(shui)(shui)(shui)機(ji)(ji)水(shui)(shui)(shui)系統是(shi)(shi)(shi)否(fou)漏水(shui)(shui)(shui);進、出水(shui)(shui)(shui)口(kou)是(shi)(shi)(shi)否(fou)暢(chang)通(tong);水(shui)(shui)(shui)泵是(shi)(shi)(shi)否(fou)正常(chang)工作(zuo)。聽風(feng)冷(leng)冷(leng)水(shui)(shui)(shui)機(ji)(ji)組的壓縮機(ji)(ji)工作(zuo)是(shi)(shi)(shi)否(fou)正常(chang)、異(yi)常(chang)，風(feng)機(ji)(ji)、水(shui)(shui)(shui)泵工作(zuo)是(shi)(shi)(shi)否(fou)有噪(zao)音，噪(zao)音是(shi)(shi)(shi)否(fou)過大。風(feng)冷(leng)式冷(leng)水(shui)(shui)(shui)機(ji)(ji)組在運(yun)行過程中，正常(chang)情況(kuang)下振(zhen)動輕微，噪(zao)聲(sheng)小。

4. 通風(feng)系(xi)統:檢(jian)查風(feng)冷(leng)冷(leng)水機(ji)的空氣濾網、熱交換器(qi)盤(pan)管、翅片(pian)是(shi)否(fou)灰塵過多(duo);進(jin)出風(feng)口是(shi)否(fou)暢(chang)通;風(feng)機(ji)、風(feng)機(ji)葉片(pian)工作是(shi)否(fou)正常(chang);風(feng)力是(shi)否(fou)正常(chang)，水系(xi)統是(shi)否(fou)正常(chang)。
