style="text-indent:25px">制冷設(shè)備抽真空有三種方法：a、低壓單側(cè)抽真空，直接將壓力表藍(lán)色表管（低壓表/真空表）接在空調(diào)的大管工藝口上（低壓管），然后關(guān)閉紅色表管（高壓表）的高壓閥門（閥門1），然后啟動真空泵，隨即打開低壓閥門（閥門2）進(jìn)行抽真空，注意觀察低壓壓力表的指針變化，一般抽30分鐘或指針指在-0.06Mpa位置，將低壓表的閥門關(guān)閉，在切斷真空泵電源。b、高低壓雙側(cè)抽真空就是在空調(diào)高、低壓管上的工藝口分別接上管然后進(jìn)行抽真空。c、復(fù)式抽真空:就是對整個制冷系統(tǒng)進(jìn)行二次以上的抽真空，以獲得理想的真空度，經(jīng)過一次抽真空后，制冷系統(tǒng)內(nèi)部保持了一定的真空度。此時關(guān)閉高、低壓表的閥門，去掉真空泵接上冷劑鋼瓶向系統(tǒng)內(nèi)充注冷劑（一般充1~2Kg就可以了）；啟動壓縮機(jī)運(yùn)轉(zhuǎn)數(shù)分鐘，使系統(tǒng)內(nèi)殘存的氣體與制冷劑混合，再開啟真空泵進(jìn)行第二次抽真空，抽空時間至少在30分鐘以上，這樣能使系統(tǒng)內(nèi)的氣體進(jìn)一步減少，以達(dá)到規(guī)定的真空度。這種方法比單側(cè)抽真空效果好，但要損耗一定的冷劑量和時間。</p><p style="text-indent:25px">制冷設(shè)備造成排氣溫度升高的主要原因有:(1)、吸氣溫度較高，制冷劑蒸汽經(jīng)壓縮后排氣溫度也就較高。(2)、冷凝溫度升高，冷凝壓力也就高，造成排氣溫度升高。(3)、排氣閥片被擊碎，高壓蒸汽反復(fù)被壓縮而溫度上升，氣缸與氣缸蓋燙手，排氣管上的溫度計指示值也升高。影響排氣溫度升高的實(shí)際因素有:(1)、中間冷卻效率低，或者中冷器內(nèi)水垢過多影響換熱，則后面級的吸氣溫度必然偏高，排氣溫度也會升高。(2)、氣閥漏氣，活塞環(huán)漏氣，不僅影響到排氣溫度升高，而且也會使級間壓力變化，只要壓縮比高于正常值就會使排氣溫度升高。(3)、此外，水冷式機(jī)器，缺水或水量不足均會使排氣溫度升高。冷凝壓力不正常以及排氣壓力降**冷機(jī)常用于工農(nóng)業(yè)生產(chǎn)和日常生活中。</p><div
