style="font-size:14px;">在制冷設(shè)備中，冷凝器是冷庫(kù)工程制冷系統(tǒng)中主要的熱交換設(shè)備之一，其作用是把裝配式冷庫(kù)安裝壓縮機(jī)排出的高溫制冷劑過熱蒸氣冷卻和冷凝為高壓液體。制冷劑在冷凝器中放出的熱量由冷卻介質(zhì)帶走。按冷卻介質(zhì)來分，裝配式冷庫(kù)工程安裝冷凝器主要分為風(fēng)冷式和水冷式。外殼是用鋼板卷制焊接成的圓柱體，冷庫(kù)安裝殼管式冷凝器分為立式和臥式兩種。立式殼管式冷凝器。筒體兩端焊有多孔管板，孔內(nèi)對(duì)應(yīng)有傳熱管，用于對(duì)制冷劑的冷卻。其特點(diǎn)是結(jié)構(gòu)龐大，耗材多;冷卻水流速低，易結(jié)垢，冷卻水消耗量大，適用于水源充足、水質(zhì)較差的地區(qū)。臥式殼管式冷凝器的結(jié)構(gòu)與立式類似，當(dāng)制冷劑為氨時(shí)，傳熱管采用無(wú)縫鋼管，制冷劑為氟利昂時(shí)，傳熱管采用低肋銅管。臥式殼管式冷凝器的傳熱系數(shù)較高，冷卻水耗用量較少，但對(duì)水質(zhì)要求較高，普遍用于大、中、小型冷庫(kù)氨和氟利昂制冷系統(tǒng)。</span></p><div
