style="text-indent:25px">按照冷卻目的和冷量利用方式的不同，冷凍機(jī)大體可分為冷藏用制冷裝置、試驗(yàn)用制冷裝置、生產(chǎn)用制冷裝置和空調(diào)用制冷裝置四類。冷藏用冷凍機(jī)主要用于在低溫條件下貯藏或運(yùn)輸食品和其他貨品，包括各種冰箱、冷庫、冷藏車、冷藏船和冷藏集裝箱等。制冷機(jī)將具有較低溫度的被冷卻物體的熱量轉(zhuǎn)移給環(huán)境介質(zhì)從而獲得冷量的機(jī)器。從較低溫度物體轉(zhuǎn)移的熱量習(xí)慣上稱為冷量。制冷機(jī)內(nèi)參與熱力過程變化（能量轉(zhuǎn)換和熱量轉(zhuǎn)移）的工質(zhì)稱為制冷劑。制冷的溫度范圍通常在120K以上，120K以下屬深低溫技術(shù)范圍。制冷機(jī)普遍應(yīng)用于工農(nóng)業(yè)生產(chǎn)和日常生活中。</p><p style="text-indent:25px">冷凍機(jī)常見的故障問題解析：吸氣溫度過低。主要是蒸發(fā)器供液量偏大導(dǎo)致吸氣過熱度低造成的。(1)制冷劑充注量太多：占據(jù)了冷凝器內(nèi)部分容積而使冷凝壓力增高，進(jìn)入蒸發(fā)器的液體隨之增多。蒸發(fā)器中液體不能完全氣化，使壓縮機(jī)吸人的氣體中帶有液體微滴。這樣，回氣管道的溫度下降，但蒸發(fā)溫度因壓力未下降而未變化，過熱度減小。即使關(guān)小膨脹閥也無明顯改善。(2)膨脹閥開啟度過大：由于感溫元件綁扎過松、與回氣管接觸面積小，或者感溫元件未用絕熱材料包扎及其包扎位置錯(cuò)誤等，致使感溫元件所測(cè)溫度不準(zhǔn)確，接近環(huán)境溫度，使膨脹閥動(dòng)作的開啟度增大，導(dǎo)致供液量過多。制冷壓縮機(jī)吸入的氣體允許一定的過熱度，但過熱度太大，其產(chǎn)冷量降低，相對(duì)耗電量增加。</p><div
