style="text-indent:25px">螺桿冷凍壓縮機(jī)冷凝器效率低，主要影響供液溫度和是否能夠形成液體，我們知道，膨脹閥理想狀態(tài)下，是全液供給，這樣的話(huà)系統(tǒng)的效率較高，制冷量較大。而且，大型機(jī)組上基本都有附儲(chǔ)，主要用在油冷方面。所以保持冷凝器的效率高尤為重要。其故障主要是：冷卻方式選型不對(duì)，蒸發(fā)面積不足，冷卻介質(zhì)不足，熱交換不足引起的，所以檢查時(shí)主要檢查風(fēng)機(jī)，水泵，翅片等關(guān)鍵。冷凝效果太好也不行，比如環(huán)溫偏低，冷凝效果太好，造成液體進(jìn)入蒸發(fā)器效率更高，此時(shí)，吸氣過(guò)熱度很低，膨脹閥靈敏度偏低，就會(huì)造成開(kāi)機(jī)液擊?；蛘吲艢鈮毫εc吸氣壓力差值不足，對(duì)于壓差供油方式的螺桿機(jī)是致命的。</p><p style="text-indent:25px">單級(jí)制冷機(jī)是應(yīng)用比較普遍的一類(lèi)制冷機(jī)，它可以應(yīng)用于制冰、空調(diào)、食品冷藏及工業(yè)生產(chǎn)過(guò)程等方面。單級(jí)制冷循環(huán)是指制冷劑在制冷系統(tǒng)內(nèi)相繼經(jīng)過(guò)壓縮、冷凝、節(jié)流、蒸發(fā)四個(gè)過(guò)程，便完成了單級(jí)制冷機(jī)的循環(huán)，即達(dá)到了制冷的目的。制冷系統(tǒng)由蒸發(fā)器、單級(jí)壓縮機(jī)、油分離器、冷凝器、貯氨器、氨液分離器、節(jié)流閥及其它附屬設(shè)備等組成，相互間通過(guò)管子聯(lián)接成一個(gè)封閉系統(tǒng)。其中，蒸發(fā)器是輸送冷量的設(shè)備，液態(tài)制冷劑蒸發(fā)后吸收被冷卻物體的熱量實(shí)現(xiàn)制冷；壓縮機(jī)是系統(tǒng)的心臟，起著吸入、壓縮、輸送制冷劑蒸汽的作用；油分離器用于沉降分離壓縮后的制冷劑蒸汽中的油；冷凝器將壓縮機(jī)排出的高溫制冷劑蒸汽冷凝成為飽和液體；貯氨器用來(lái)貯存冷凝器里冷凝的制冷劑氨液，調(diào)節(jié)冷凝器和蒸發(fā)器之間制冷劑氨液的供需關(guān)系；氨液分離器是氨重力供液系統(tǒng)中的重要附屬設(shè)備；節(jié)流閥對(duì)制冷劑起節(jié)流降壓作用同時(shí)控制和調(diào)節(jié)流入蒸發(fā)器中制冷劑液體的流量，并將系統(tǒng)分為高壓側(cè)和低壓側(cè)兩部分。對(duì)于特定的制冷劑，選擇不同的冷凍機(jī)壓縮機(jī)直接關(guān)系到運(yùn)行的能耗。</p><div
