現(xiàn)在家家戶戶都離不開冰箱，冰箱對我們的生活有非常大的幫助，如果有吃不完的食物或者需要儲(chǔ)存食物都可以存放在冰箱里，以防止食品的變質(zhì)。這樣既方便又容易。但是由于冰箱夜以繼?地?作，有時(shí)難免會(huì)出現(xiàn)些故障，出現(xiàn)故障該怎么維修呢？

冰箱構(gòu)造

維修冰箱，首先我們需要了解冰箱的構(gòu)造。

家用電冰箱由箱體、制冷系統(tǒng)、溫度控制裝置三部分組成。

箱體

箱體的組成：外殼、內(nèi)襯、絕熱層、臺(tái)面。

箱體的基本作用是絕熱，絕熱性能的優(yōu)劣直接關(guān)系到箱體的保溫性能。

箱體的隔熱功能主要是從以下幾個(gè)方面來實(shí)現(xiàn)的：

1、外殼與內(nèi)襯之間填充絕熱材料。

2、箱門裝有磁性密封條防止冷氣外漏和熱空氣侵入。

3、箱頂?shù)捻敯逑旅鎵|有高密度聚苯乙烯泡沫板，起隔熱作用。

制冷系統(tǒng)

制冷系統(tǒng)組成：壓縮機(jī)、冷凝器、蒸發(fā)器、毛細(xì)管。

制冷系統(tǒng)自成一個(gè)封閉的循環(huán)系統(tǒng)。其中蒸發(fā)器安裝在電冰箱內(nèi)部的上方，其他部件安裝在電冰箱的背面。

工作原理：系統(tǒng)里充灌了一種叫“氟里12(CF2Cl2，國際符號(hào)R12)”的物質(zhì)作為制冷劑（氟利昂類包括氟利昂12和氟利昂11等等是一般傳統(tǒng)的制冷劑，現(xiàn)在更多的是新興的無氟制冷劑如R600a、R404a等，不過制冷原理是一樣的）。氟里昂12在蒸發(fā)器里由低壓液體汽化為氣體，吸收冰箱內(nèi)的熱量，使箱內(nèi)溫度降低。變成氣態(tài)的氟里昂12被壓縮機(jī)吸入，靠壓縮機(jī)把它壓縮成高溫高壓的氣體，再排入冷凝器。在冷凝器中氣態(tài)的氟里昂12不斷向周圍空間放熱，逐步液化成液體。這些高壓液體必須流經(jīng)毛細(xì)管，節(jié)流降壓才能緩慢流入蒸發(fā)器，維持在蒸發(fā)器里繼續(xù)不斷地汽化，吸熱降溫。就這樣，冰箱利用電能做功，借助制冷劑的物態(tài)變化，把箱內(nèi)蒸發(fā)器周圍的熱量搬送到箱后冷凝器里去放出，如此周而復(fù)始不斷地循環(huán)，以達(dá)到制冷目的。

內(nèi)部汽化吸熱?→?外部液化放熱→?箱內(nèi)溫度降低

溫度控制裝置

冰箱的溫度控制裝置叫溫度控制器。它的主要作用是當(dāng)箱內(nèi)溫度過高時(shí)接通壓縮機(jī)，使制冷系統(tǒng)工作，從而使箱溫降下來，當(dāng)箱溫降至要求的溫度時(shí)，使壓縮機(jī)斷電。

故障檢測方法

冰箱故障的檢查方法一般可分為問、看、聽、摸、測試等。通過檢查，綜合分析判斷，逐漸縮小故障范圍，找出故障點(diǎn)。

問

首先問明冰箱的使用情況、故障現(xiàn)象及使用年限，特別是舊機(jī)器，要了解機(jī)器的故障史及以前維修后的使用情況，對曾維修過制冷系統(tǒng)的機(jī)器，要多留意冰堵、臟堵、混入空氣、冷凍油是否變質(zhì)等故障。

看

1、首先看蒸發(fā)器結(jié)霜的情況，在壓縮機(jī)運(yùn)轉(zhuǎn)的情況下，如果出現(xiàn)蒸發(fā)器表面無霜、結(jié)不滿霜或結(jié)霜不實(shí)等情況，都說明制冷系統(tǒng)工作不正常。

2、冰箱冷凍室結(jié)冰，說明溫控器溫差過大，停機(jī)時(shí)間過長等因素造成的，直冷式雙門冰箱的冷藏室蒸發(fā)器總是結(jié)滿霜而無結(jié)霜、化霜交替變化，說明溫控器發(fā)生故障。

3、檢查制冷系統(tǒng)中管路的各個(gè)焊接處及蒸發(fā)器表面，看是否有滲漏的痕跡，凡滲漏處都會(huì)有油漬。

4、查看壓縮機(jī)回氣管是否結(jié)霜，如結(jié)霜，則說明制冷劑沖入量過多，對于間冷式冰箱，如壓縮機(jī)回氣管結(jié)霜，還應(yīng)考慮是否由于風(fēng)扇不轉(zhuǎn)而引起。遇到這種情況，可以打開箱門，按下門框按鈕，查看風(fēng)扇是否旋轉(zhuǎn)。

5、查看箱門是否有縫隙。如果箱門有縫隙，則冰箱保溫性能差，導(dǎo)致壓縮機(jī)開機(jī)時(shí)間長，停機(jī)時(shí)間短，而且冰箱結(jié)霜多。

聽

1、接通冰箱電源，如果聽到啟動(dòng)器“叭嗒”一聲，壓縮機(jī)在0.2秒至0.5秒內(nèi)啟動(dòng)，隨后壓縮機(jī)發(fā)出輕微而且有節(jié)奏的運(yùn)轉(zhuǎn)聲，說明壓縮機(jī)啟動(dòng)正常。如壓縮機(jī)發(fā)出沉悶的“嗡嗡”聲，而后連續(xù)聽到“叭嗒”的啟動(dòng)器觸點(diǎn)斷開、吸合的聲音，有時(shí)還帶有壓縮機(jī)的振動(dòng)聲，最后可以聽到熱保護(hù)器“叭”的一聲響，隨后切斷壓縮機(jī)電源。此故障可以考慮以下原因：

a、電源電壓低，壓縮機(jī)卡缸、抱缸軸。

b、電動(dòng)機(jī)掃堂。

c、電動(dòng)機(jī)繞組短路。

d、電動(dòng)機(jī)啟動(dòng)繞組開路。

e、氣路系統(tǒng)管路堵塞。

f、啟動(dòng)繼電器故障等。使用排除法，確定故障原因。

2、壓縮機(jī)運(yùn)轉(zhuǎn)時(shí)，機(jī)殼內(nèi)有明顯的噴氣聲，說明壓縮機(jī)排氣緩沖管斷裂漏氣。若壓縮機(jī)機(jī)殼有破裂聲，說明壓縮機(jī)高、低壓閥片破裂、漏氣。壓縮機(jī)剛停機(jī)時(shí)，聽到機(jī)殼內(nèi)有明顯的跑氣聲音，說明壓縮機(jī)閥板的高低壓紙墊被擊穿、排氣減震管泄漏、閥片磨損或閥片、閥口處積碳。壓縮機(jī)運(yùn)轉(zhuǎn)時(shí)，如果機(jī)殼發(fā)出“當(dāng)當(dāng)”的撞擊聲，說明壓縮機(jī)內(nèi)支撐彈簧斷裂或疲勞變形。

3、高壓液態(tài)制冷劑通過毛細(xì)管進(jìn)入蒸發(fā)器，迅速蒸發(fā)沸騰，同時(shí)發(fā)出“嘶嘶”的氣流聲音，并時(shí)常伴流水的聲音，屬于正?，F(xiàn)象。如果聽到蒸發(fā)器內(nèi)有“嘰嘰”聲，或者有斷斷續(xù)續(xù)的憋氣聲，故障通常為臟堵、油堵或者冰堵。周期性較長的斷續(xù)噴氣聲一般為冰堵。若蒸發(fā)器內(nèi)只有氣流聲，而且不結(jié)霜，說明系統(tǒng)內(nèi)制冷劑基本漏完。

4、冰箱有時(shí)發(fā)出斷斷續(xù)續(xù)的噪音，往往是由于冰箱支腳落地不穩(wěn)，制冷系統(tǒng)管路相互碰撞以及壓縮機(jī)與箱體底座螺絲松動(dòng)等原因引起共振造成的。

摸

冰箱正常運(yùn)行時(shí)，制冷系統(tǒng)各個(gè)部分的溫度通過觸摸，可以對制冷系統(tǒng)狀況有個(gè)大致的判斷。(制冷系統(tǒng)各個(gè)部分的溫度還受環(huán)境溫度的影響，環(huán)境溫度升高時(shí)，冷凝器、過濾器、回氣管和壓縮機(jī)的溫度明顯升高，反之，上述部分的溫度明顯降低。)

1、壓縮機(jī)運(yùn)轉(zhuǎn)時(shí)，觸摸冷凝器上部，應(yīng)很熱(大于55℃)。如不熱，可能是制冷系統(tǒng)漏氣、堵塞或壓縮機(jī)沒有排氣壓力等故障。

2、正常時(shí)，觸摸干燥過濾器應(yīng)有熱的感覺(約55℃)。如制冷系統(tǒng)過臟，會(huì)造成干燥過濾器溫度升高，對于剛剛維修過的冰箱，如果干燥過濾器溫度過高，一般為毛細(xì)管阻流偏大，制冷劑充入量過大。

3、壓縮機(jī)正常工作時(shí)，觸摸壓縮機(jī)回氣管，應(yīng)沒有熱感(接近于環(huán)境溫度)。如果溫度高，說明系統(tǒng)少制冷劑，管路微堵或系統(tǒng)中混入空氣。如果感覺到冷或者有露水甚至結(jié)霜時(shí)，說明制冷劑充入量過多。

4、壓縮機(jī)機(jī)殼的溫度一般在70℃以下。即使在夏季，冰箱首次開機(jī)時(shí)，壓縮機(jī)經(jīng)過連續(xù)長時(shí)間的工作，機(jī)殼溫度也不超過85℃。

5、如果蒸發(fā)器上結(jié)的霜用手一摸就脫落(稱為虛霜)，并且壓縮機(jī)回氣管結(jié)滿霜，說明充入的制冷劑過多或新?lián)Q的毛細(xì)管過粗、過短。

6、用手觸摸蒸發(fā)器表面，如果發(fā)現(xiàn)蒸發(fā)器結(jié)不滿霜，說明系統(tǒng)制冷劑不足或毛細(xì)管半堵塞。

測試

通過測量冰箱的溫度、壓力、開機(jī)與停機(jī)比、運(yùn)轉(zhuǎn)電流以及壓縮機(jī)的絕緣電阻和直流電阻等，對冰箱進(jìn)行檢查。

1、測溫度

用電機(jī)溫度計(jì)測量電冰箱的溫度。電冰箱的溫度按國家標(biāo)準(zhǔn)吸氣溫度為三十二攝氏度，蒸發(fā)溫度為負(fù)二十三攝氏度一下，排氣溫度為五十五攝氏度左右，過冷溫度為三十二攝氏度左右。

1、冰箱靠近墻面放置會(huì)導(dǎo)致冰箱發(fā)燙，也不能在冰箱的周圍覆蓋東西，這樣都會(huì)阻礙冰箱散熱，使溫度上升，應(yīng)該保持冰箱有足夠的空間散熱。

2、在使用冰箱的時(shí)候不要打開頻繁，頻繁的打開冰箱會(huì)讓里的溫度升高，加大冰箱的工作量，冰箱長期處于運(yùn)轉(zhuǎn)狀態(tài)就會(huì)使溫度更高的。這時(shí)要減少開冰箱的次數(shù)。

3、停用之后特別是在夏季溫度很高的時(shí)候，冰箱要達(dá)到設(shè)定的制冷溫度會(huì)需要很長時(shí)間，長時(shí)間的運(yùn)轉(zhuǎn)就會(huì)使冰箱的溫度升高，冰箱一旦使用最好不要停用了。

2、測壓力

冰箱的正常壓力值在0.03~0.08mpa。

a、吸氣壓力過高，通常由：制冷劑充入過多、新?lián)Q毛細(xì)管過短、壓縮機(jī)性能*的原因引起。

b、出現(xiàn)吸氣壓力為負(fù)壓時(shí)，通常由：制冷劑不足、系統(tǒng)內(nèi)有堵塞現(xiàn)象、新?lián)Q毛細(xì)管太細(xì)、太長。

2、測量冰箱的開機(jī)與停機(jī)之比

冰箱的開機(jī)與停機(jī)之比與它的制冷系統(tǒng)、保溫性能、溫控器性能、調(diào)節(jié)位置、環(huán)境溫度、電路系統(tǒng)、冰箱內(nèi)食品的多少以及開門次數(shù)等有著直接的關(guān)系。

3、測量工作電流

1、如果工作電流大于額定電流，說明制冷劑充入量過多，制冷系統(tǒng)微堵、壓縮機(jī)局部短路。

2、如果工作電流小于額定電流，說明制冷系統(tǒng)有泄漏或系統(tǒng)完全堵塞。

3、測量絕緣電阻和直流電阻：(對于匝間短路不嚴(yán)重或匝間絕緣不良的電機(jī)繞組，用電阻測量方法很難分辨電機(jī)故障，因此只能采用測量工作電流的方法來判斷)。

缺少制冷劑，或蒸發(fā)器內(nèi)有沉積的冷凍機(jī)油，導(dǎo)致壓縮機(jī)效率降低。

冰箱故障分類

電冰箱的故障可分為電氣系統(tǒng)故障和制冷系統(tǒng)故障兩大類。

電氣系統(tǒng)故障分析

電氣系統(tǒng)主要包括溫控部分和壓縮機(jī)電動(dòng)機(jī)控制部分。由此而引起的故障現(xiàn)象是電冰箱接通電源后壓縮機(jī)不起動(dòng)和接通電源后壓縮機(jī)運(yùn)轉(zhuǎn)不停。

1、首先用萬用表歐姆擋測量冰箱電源插頭的阻值。

壓縮機(jī)的三個(gè)接線端子以及與起動(dòng)器之間的接線情況如圖所示：C——公共端、M——運(yùn)行端、S——起動(dòng)端。

各繞組間直流電阻值如下：運(yùn)行繞組C、M兩端約10.5Ω；起動(dòng)繞組C、S兩端約22Ω；而運(yùn)行和起動(dòng)繞組阻值的和即S、M端的阻值約為32.5Ω。正常時(shí)電路所有的開關(guān)觸點(diǎn)都接通，對于重錘起動(dòng)器式的冰箱，因重錘式起動(dòng)器觸點(diǎn)未通電而未接通，回路阻值為壓縮機(jī)運(yùn)行繞組的阻值，一般為10—20Ω左右，對于PTC起動(dòng)冰箱，回路的直流電阻為起動(dòng)器20Ω阻值與起動(dòng)繞組串聯(lián)后再與運(yùn)行繞組并聯(lián)，所以其電阻略小于壓縮機(jī)運(yùn)行繞組的阻值。

通過測得的阻值來判斷電路的工作狀態(tài)，阻值偏大時(shí)，要檢查溫度控制器、過載保護(hù)器、壓縮機(jī)電動(dòng)機(jī)以及線路和觸點(diǎn)接觸情況，阻值偏小時(shí)一般是短路，主要檢查壓縮機(jī)電動(dòng)機(jī)及其線路。

2、要進(jìn)一步判斷還要對冰箱通電檢查。

通電前先檢查溫控器開關(guān)是否正常。如溫度控制器裝在電冰箱的冷藏室內(nèi)，當(dāng)放置的環(huán)境溫度低于設(shè)計(jì)溫度時(shí)不會(huì)起動(dòng)運(yùn)轉(zhuǎn)，故有的冰箱設(shè)計(jì)了冬季補(bǔ)償開關(guān)，補(bǔ)償開關(guān)打開后則溫度控制器感溫管附近的加熱器開始加熱，強(qiáng)制升溫使壓縮機(jī)運(yùn)轉(zhuǎn)，目的是犧牲冷藏室的正常溫度而保證冷凍室的溫度。

如果溫控器內(nèi)的開關(guān)都正常，而通電后壓縮機(jī)不起動(dòng)，可用一根導(dǎo)線短接重錘式起動(dòng)器的兩個(gè)靜觸點(diǎn)，注意導(dǎo)線短接時(shí)間不要太長，以不超過2s為宜，時(shí)間長將會(huì)使起動(dòng)繞組燒壞。如果短接后冰箱能起動(dòng)，說明起動(dòng)器有故障，重錘式起動(dòng)器長期起動(dòng)易使觸點(diǎn)燒壞，測量時(shí)拆下起動(dòng)器，用萬用表歐姆RX1擋，將兩表筆插入接線柱插孔內(nèi)。起動(dòng)器正著放時(shí)相當(dāng)于正常運(yùn)轉(zhuǎn)狀態(tài)，即未接通，萬用表測量阻值為無窮大；將起動(dòng)器倒過來時(shí)相當(dāng)于起動(dòng)狀態(tài)，萬用表指示為0Ω，則說明起動(dòng)器是好的。

如果用導(dǎo)線短接后仍不能起動(dòng)，就需要檢查保護(hù)器?？捎枚探臃z查保護(hù)器，將保護(hù)器的兩個(gè)接線銅片短接起來，如果冰箱能夠起動(dòng)運(yùn)轉(zhuǎn)，說明保護(hù)器有故障，可能是電熱絲燒斷或碟形雙金屬片受阻不能下翻，如果冰箱仍不能起動(dòng)，則是壓縮機(jī)或起動(dòng)器有問題。檢查時(shí)，把起動(dòng)器和保護(hù)器拆下，露出電動(dòng)機(jī)的三根接線柱。測每兩個(gè)接線柱之間的電阻值，如正常，說明電動(dòng)機(jī)繞組沒有故障。如不正常，不要急于拆開壓縮機(jī)，可以采用直接接通電源的方法進(jìn)行檢查。具體辦法是：用帶有電源插頭的兩根電源線接在M、C接線柱上，也就是運(yùn)行繞組上，再用螺釘旋具作為導(dǎo)線同時(shí)碰觸M和S端，然后把插頭插入電源插座，如果電動(dòng)機(jī)和壓縮機(jī)沒有故障，就會(huì)起動(dòng)。起動(dòng)2s左右，就要把螺釘旋具移開，電動(dòng)機(jī)進(jìn)入正常運(yùn)轉(zhuǎn)。如果檢查壓縮機(jī)能起動(dòng)運(yùn)轉(zhuǎn)，說明電動(dòng)機(jī)沒有故障，故障發(fā)生在電動(dòng)機(jī)外部，可能是外引線折斷或接線柱接觸不良，也可能是環(huán)境溫度過低等。否則為壓縮機(jī)故障。

制冷系統(tǒng)故障分析

電冰箱不制冷

電冰箱運(yùn)轉(zhuǎn)不停，但是不制冷，冷凝器不熱，蒸發(fā)器不涼。這種故障一般出現(xiàn)在制冷系統(tǒng)。

可能原因是制冷劑泄漏，或者冰堵、臟堵，或是壓縮機(jī)有故障。由于制冷系統(tǒng)是封閉的，所以可通過觀察管路表面有無油污、用手觸摸各部分的溫度、耳聽運(yùn)行聲音來檢查。

1、檢查管路表面是否有油污

仔細(xì)檢查冷凝器、過濾器、毛細(xì)管、蒸發(fā)器；吸氣管、壓縮機(jī)外殼及管路結(jié)合處。如果發(fā)現(xiàn)有油污，說明制冷劑泄漏。這時(shí)可切開壓縮機(jī)的工藝管。如果有少量的制冷劑噴出，就進(jìn)一步證明是制冷劑泄漏。

如果沒有油污，則需要進(jìn)一步檢查壓縮機(jī)的溫度。

2、檢查壓縮機(jī)的溫度

用手摸壓縮機(jī)，如果壓縮機(jī)的溫度不太高，和運(yùn)轉(zhuǎn)時(shí)差不多，說明管路暢通，沒有堵塞現(xiàn)象，而可能是高壓緩沖管破裂、活塞穿孔、排氣閥同吸氣閥短路等。這時(shí)可切開高壓排氣管，排出制冷劑。

3、檢查壓縮機(jī)開機(jī)時(shí)的情況

切斷電冰箱的電源，打開箱門；使制冷系統(tǒng)各個(gè)部件恢復(fù)到室溫。然后接通電源，電冰箱啟動(dòng)運(yùn)轉(zhuǎn)。如果開始時(shí)蒸發(fā)器結(jié)霜較好，冷凝器發(fā)熱，低壓吸氣管發(fā)涼；由冰箱上部能聽到氣流聲和水流聲，但過一會(huì)兒，蒸發(fā)器結(jié)霜融化，只在毛細(xì)管同蒸發(fā)器結(jié)合部位結(jié)有少量霜；冷凝器不熱，低壓吸氣管不涼，用耳朵貼近電冰箱上部聽不到聲音，說明出現(xiàn)了冰堵。這時(shí)如果用熱毛巾敷在毛細(xì)管同蒸發(fā)器的結(jié)合處，又能重新制冷，則進(jìn)一步證實(shí)是冰堵。

如果開機(jī)的時(shí)候不見蒸發(fā)器結(jié)霜，冷凝器不熱，低壓氣管不涼，用耳朵貼近電冰箱上部聽不到聲音，則可以初步認(rèn)為發(fā)生了臟堵。這時(shí)，可以切斷高壓排氣管，排出制冷劑，用手指按住排氣管，啟動(dòng)壓縮機(jī)，如果手指感到有較大的壓力，說明管路發(fā)生臟堵。

電冰箱制冷效果差

電冰箱運(yùn)轉(zhuǎn)不停，但箱內(nèi)溫度達(dá)不到要求，制冷效果差。這可能是由于使用不當(dāng)或箱門關(guān)閉不嚴(yán)造成的。也可能是制冷系統(tǒng)故障引起的。一般應(yīng)先檢查使用情況和箱門情況，再檢查制冷系統(tǒng)。

1、檢查使用情況

首先要了解環(huán)境溫度。如果高于43℃，制冷效果差一些是正常的。如果環(huán)境溫度不高，要打開箱門檢查。如果箱內(nèi)食品太多，特別是放入了溫度高的食品，食品釋放出大量的熱量；或者打開箱門次數(shù)太多，外界熱空氣不斷進(jìn)人箱內(nèi)，或者未及時(shí)化霜等，所有這些都會(huì)使電冰箱長時(shí)間運(yùn)轉(zhuǎn)不停，制冷效果差。

2、檢查箱門

電冰箱箱門關(guān)閉不嚴(yán)，熱空氣會(huì)從縫隙處不斷進(jìn)入箱內(nèi)。這可能是磁性門封條失去磁性、老化變形，或是箱門翹曲造成的。

3、檢查制冷系統(tǒng)

如果使用情況正常，箱門又能關(guān)閉嚴(yán)密，那么制冷效果差的故障就出在制冷系統(tǒng)。由于制冷系統(tǒng)仍能工作，因此，可能是制冷劑部分泄漏、部分冰堵或部分臟堵，也可能是壓縮機(jī)內(nèi)部故障。

檢查的順序是首先觀察管路表面有無油污。如果有油污，說明制冷劑部分泄漏，這時(shí)可以切開工藝管，灌入適量的氟里昂制冷劑，再次啟動(dòng)運(yùn)轉(zhuǎn)。如果運(yùn)轉(zhuǎn)正常，證明是制冷劑部分泄漏。如果管路表面沒有油污，可檢查開機(jī)時(shí)的情況。如果開機(jī)時(shí)制冷正常，蒸發(fā)器結(jié)霜良好，在電冰箱上部能聽到氣流聲和水流聲，但過了一會(huì)兒制冷效果變差，只能聽到微弱的氣流聲和流水聲，說明是部分冰堵。

如果開機(jī)時(shí)制冷效果就差，用耳朵貼近冰箱上部只能聽到微弱的氣流聲和水流聲，這可能是臟堵或壓縮機(jī)內(nèi)部故障，需要進(jìn)一步檢查。這時(shí)，可切開工藝管，灌入適量的氟里昂制冷劑，并接入氣壓表，啟動(dòng)壓縮機(jī)。如果氣壓表所示氣壓下降到正常值（0.06～0.08MPa）以下，說明壓縮機(jī)內(nèi)部沒有故障，只是管路有部分臟堵。如果氣壓下降到正常值以上，說明壓縮機(jī)性能下降，嚴(yán)重時(shí)需要拆開壓縮機(jī)詳細(xì)檢查和修理。

如果制冷系統(tǒng)混入空氣，或者制冷劑充加過多或不足，都可能影響制冷效果。

制冷系統(tǒng)中充加過多的制冷劑，會(huì)使過多的制冷劑在蒸發(fā)器內(nèi)不能很好蒸發(fā)，液體制冷劑返回壓縮機(jī)中，這樣壓縮機(jī)的吸氣量減少，制冷系統(tǒng)低壓端壓力升高，又影響蒸發(fā)器內(nèi)制冷劑的蒸發(fā)量；造成制冷能力下降。同時(shí)，過多的制冷劑會(huì)占去冷凝器的一部分容積，減少散熱面積，使冷凝器的冷卻效率降低，吸氣壓力和蒸發(fā)溫度也相應(yīng)提高，吸氣管出現(xiàn)結(jié)霜現(xiàn)象。遇到這種情況，必須及時(shí)將多余的制冷劑排出制冷系統(tǒng)，否則不但不能提高降溫效果，反而使壓縮機(jī)有液擊沖缸的危險(xiǎn)。

制冷系統(tǒng)充加的制冷劑過少時(shí)，會(huì)使蒸發(fā)器的蒸發(fā)表面積得不到充分利用，制冷量降低，蒸發(fā)器表面部分結(jié)霜，吸氣管溫度偏高。遇到這種情況，可以補(bǔ)充適量的制冷劑。

冰箱的保養(yǎng)

定期適當(dāng)保養(yǎng)可以延長冰箱的使用壽命。保養(yǎng)冰箱前務(wù)必拔下電源插頭。

1、經(jīng)常清理冰箱背面或底部冷凝器和壓縮機(jī)上的灰塵?？墒褂梦鼔m器或毛刷除塵。注意不要用濕布去擦冷藏器和壓縮機(jī)上灰塵。

2、冰箱長期停用時(shí)，應(yīng)先切斷電源，取出箱內(nèi)一切食品，將箱內(nèi)外清理干凈，敞開箱門數(shù)日，使箱內(nèi)充分干燥并散掉冰箱內(nèi)的異味。

3、檢查排水管。如果排水管堵塞，水就會(huì)漏到冰箱內(nèi)。要用鐵絲捅一捅排水管，除去積在排水管上的東西。

4、不要忽略門封膠條的清洗，將漂白劑用10倍的水稀釋后用牙刷蘸濕清洗，最后用水將漂白劑沖去。膠條臟污易老化，會(huì)影響冰箱的密封性，增加耗電量。

5、檢查振動(dòng)、噪音以及壓縮機(jī)的溫度。運(yùn)行中摸壓縮機(jī)外殼，不應(yīng)有明顯的振動(dòng)感，白天不應(yīng)聽到壓縮機(jī)明顯啟動(dòng)的聲音。

6、注意檢查電源線上是否有裂縫，防止漏電。

7、用溫水或中性洗滌劑將冰箱內(nèi)外清洗并擦干，敞開冰箱門通風(fēng)干燥一天。

清潔冰箱外殼最好每天進(jìn)行，用微濕柔軟的布每天擦拭冰箱的外殼和拉手。清理內(nèi)膽前先切斷電源，把冰箱冷藏室內(nèi)的食物拿出來。軟布蘸上清水或食具洗潔精，輕輕擦洗，然后蘸清水將洗潔精拭去。拆下箱內(nèi)附件，用清水或洗潔精清洗。清潔冰箱的“開關(guān)”、“照明燈”和“溫控器”等設(shè)施時(shí)，請把抹布或海綿擰得干一些。內(nèi)壁做完清潔后，可用軟布蘸取甘油(醫(yī)用開塞露)擦一遍冰箱內(nèi)壁，下次擦的時(shí)候會(huì)更容易。用酒精浸過的布清潔擦拭密封條。如果手邊沒有酒精，用1：1醋水擦拭密封條，消毒效果很好。用吸塵器或軟毛刷清理冰箱背面的通風(fēng)柵，不要用濕布，以免生銹。清潔完畢，插上電源，檢查溫度控制器是否設(shè)定在正確位置。
