5、經(jīng)濟(jì)器 疑有誤，均只有一進(jìn)一出，懷疑經(jīng)濟(jì)器與液冷油冷卻器應(yīng)為一體，參見下圖：且 回氣不應(yīng)到壓縮機(jī)出口管道。經(jīng)濟(jì)器的原理及結(jié)構(gòu)(是否就是：煙臺(tái)冰輪 工藝流程圖上的液冷油冷卻器，即壓力容器圖紙的油冷卻器) 配經(jīng)濟(jì)器的系統(tǒng)中，從冷凝器或貯液器出來的液體，并不直接送節(jié)流閥節(jié)流，而是首先進(jìn)入經(jīng)濟(jì)器冷卻器中進(jìn)一步冷卻，出來后的液體工質(zhì)的溫度可下降數(shù)十度，制冷量將得到提高。經(jīng)濟(jì)器冷卻器中液體的冷卻，是依靠經(jīng)幫助節(jié)流閥節(jié)流后進(jìn)入經(jīng)濟(jì)器中的中壓液體工質(zhì)，它吸取高壓液體工質(zhì)的熱量而蒸發(fā)，蒸發(fā)出來的中壓氣體被螺桿壓縮機(jī)的中間補(bǔ)氣口吸走（見流程圖）。帶經(jīng)濟(jì)器的機(jī)組特殊適合取代雙級(jí)活塞式機(jī)組，在較低蒸發(fā)溫度下經(jīng)濟(jì)運(yùn)行。

6、壓縮機(jī)的油分別系統(tǒng) 由于螺桿式制冷壓縮機(jī)工作時(shí)噴入大量的潤(rùn)滑油與制冷劑蒸汽一起排出，所以在壓縮機(jī)與冷凝器之間設(shè)置了高效的臥式油分別器。油分別器的作用是分別壓縮機(jī)排氣中攜帶的潤(rùn)滑油，使進(jìn)入冷凝器的制冷劑純潔，避開潤(rùn)滑油進(jìn)入冷凝器而降低冷凝器的效率。油分別器還有貯油器的功能。本機(jī)組接受臥式油分別器，從壓縮機(jī)排出的高壓氣體，通過排氣管進(jìn)入油分別器，降低流速，轉(zhuǎn)變方向，向油分的另一端排去。在這個(gè)過程中，大量的潤(rùn)滑油由于慣性及重力的作用沉降到油分底部，剩余的含有微量冷凍機(jī)油的氣體再通過油分濾芯，此微量冷凍機(jī)油被最終分別，通過油分別器底部的回油閥回到壓縮機(jī)中，以確保擋油板之后的筒體底部盡量少存油?？拷头?/p>

7、別器出口的過濾芯接受的是高分子復(fù)合材料，油分別效果可達(dá)10ppm，當(dāng)分油效果不夠抱負(fù)時(shí)可更換。油分別器附表一 R22飽和狀態(tài)下的熱力性質(zhì)溫度()確定壓力(Pa)比容焓汽化熱(kJ/kg)熵液體(dm3/kg)蒸汽(m3/kg)液體(kJ/kg)蒸汽(kJ/kg)液體(kJ/kg·K)蒸汽(kJ/kg·K)-401049500.709360.20575155.413388.611233.1980.824891.82505 -381150700.712300.18878157.537389.531231.9940.833931.82046 -361259400.715290.1
