style="text-indent:25px">冷凍壓縮機(jī)是作為制冷機(jī)中一重要組成部分而與系統(tǒng)中其它部件，如熱交換器，節(jié)流裝置等配合工作而獲得制冷的效果。因此，它的工作能力有必要直觀地用單位時(shí)間內(nèi)所產(chǎn)生的冷量——制冷量來表示，單位為匹它是冷凍壓縮機(jī)的重要性能指標(biāo)之一。為了便于比較和選用，有必要根據(jù)其不用的使用條件規(guī)定統(tǒng)一的工況來表示壓縮機(jī)的制冷量，根據(jù)標(biāo)準(zhǔn)規(guī)定，吸氣工質(zhì)過熱所吸收的熱量也應(yīng)包括在壓縮機(jī)的制冷量?jī)?nèi)。排熱量是壓縮機(jī)的制冷量和部分壓縮機(jī)輸入功率的當(dāng)量熱量之和，它是通過系統(tǒng)中的冷凝器排出的。這個(gè)參數(shù)對(duì)于熱泵系統(tǒng)中的壓縮機(jī)來講是一個(gè)十分重要的性能指標(biāo)；在設(shè)計(jì)制冷系統(tǒng)的冷凝器時(shí)也是必須知道的。</p><p style="text-indent:25px">冷凍機(jī)的保養(yǎng)與維護(hù)： 1、運(yùn)轉(zhuǎn)機(jī)組：要經(jīng)常觀察壓縮機(jī)的油面及回油情況及油的清潔度，發(fā)現(xiàn)油臟或油面下降要及時(shí)解決，以免造成潤(rùn)滑不良。 2、對(duì)于風(fēng)冷機(jī)組：要經(jīng)常清掃風(fēng)冷器使其保持良好的換熱狀態(tài)。對(duì)于水冷機(jī)組：要經(jīng)常檢查冷卻水的混濁程度，如冷卻水太臟，要進(jìn)行更換。檢查供水系統(tǒng)有無泡、冒、滴、漏問題。水泵工作是否正常，閥門開關(guān)是否有效，冷卻塔.風(fēng)機(jī)是否正常。對(duì)于冷風(fēng)機(jī)組：經(jīng)常檢查冷凝器出現(xiàn)結(jié)垢問題，要及時(shí)除去水垢。 3、對(duì)于風(fēng)冷機(jī)的蒸發(fā)器：要經(jīng)常檢查除霜情況，除霜是否及時(shí)有效，會(huì)影響制冷效果，導(dǎo)致制冷系統(tǒng)的回液。 4、經(jīng)常觀察壓縮機(jī)運(yùn)行狀態(tài)，檢查其排氣溫度，在換季運(yùn)行時(shí)，要特別注意系統(tǒng)的運(yùn)行狀態(tài)，及時(shí)調(diào)整系統(tǒng)供液量和冷凝溫。 5、仔細(xì)傾聽壓縮機(jī)，冷卻塔、水泵或冷凝器風(fēng)機(jī)運(yùn)轉(zhuǎn)聲音：發(fā)現(xiàn)異常及時(shí)處理，同時(shí)檢查壓縮機(jī)、排氣管及地腳的振動(dòng)情況。 6、對(duì)壓縮機(jī)的維護(hù)：初期系統(tǒng)內(nèi)部清潔度較差，在運(yùn)行30天后要更換一次冷凍油和干燥過濾器，在運(yùn)行半年之后再更換一次（要根據(jù)實(shí)際情況而定）。對(duì)于清潔度較高的系統(tǒng)，運(yùn)行半年以后也要更換一次冷凍油和干燥過濾器，以后視情況而定。冷庫機(jī)組冷凍機(jī)在初期運(yùn)轉(zhuǎn)時(shí)要細(xì)心觀察壓縮機(jī)的回油情況，并保持清潔。</p><div
