style="font-size:14px;">云南制冷設(shè)備由于其應(yīng)用范圍和冷卻目的的不同,其冷卻方式也不同,主要分為直接冷卻和間接冷卻兩種方式.直接冷卻是將制冷機的蒸發(fā)器裝設(shè)在制冷裝置的箱體或建筑物內(nèi),利用制冷劑的蒸發(fā)直接冷卻其中的空氣,靠冷空氣冷卻需要冷卻的物體.這種冷卻方式的優(yōu)點是冷卻速度快,傳熱溫差小,系統(tǒng)比較簡單,因而得到普遍應(yīng)用.間接冷卻是靠制冷機蒸發(fā)器中制冷劑的蒸發(fā),從而使載冷劑(例如鹽水)冷卻,再將載冷劑輸入制冷裝置的箱體或建筑物內(nèi),通過換熱器冷卻其中的空氣.這種冷卻方式冷卻速度慢,總傳熱溫差大,系統(tǒng)也較復(fù)雜,故只用于較少的場合,如鹽水制冰和溫度要求恒定的冷庫等.云南制冷設(shè)備種類豐富,功能齊全,制冷方法不同使用的制冷設(shè)備也有所區(qū)別,目前比較常用的是蒸氣壓縮制冷,該設(shè)備主要由壓縮機，云南工業(yè)冷庫制冷設(shè)備廠家哪家好，云南工業(yè)冷庫制冷設(shè)備廠家哪家好、冷凝器、蒸發(fā)器和節(jié)流閥組成。</span>公司目前以實現(xiàn)了產(chǎn)，云南工業(yè)冷庫制冷設(shè)備廠家哪家好、供、銷一條龍的經(jīng)營模式。云南工業(yè)冷庫制冷設(shè)備廠家哪家好</p><div

<p> <span style="font-size:14px;">1、缺油會引起嚴重的潤滑不足。缺油的根本原因不在于壓縮機奔油多少和快慢，而是系統(tǒng)回油不好。安裝油分離器可以快速回油，延長壓縮機無回油運轉(zhuǎn)時間。</span> </p> <p> <span style="font-size:14px;">2、當壓縮機比蒸發(fā)器的位置高時，垂直回氣管上沒有回油彎?；赜蛷澮M可能緊湊，以減小存油?；赜蛷澲g的間距要合適，回油彎的數(shù)量比較多時，應(yīng)該補充一些潤滑油。</span> </p> <p> <span style="font-size:14px;">3、壓縮機頻繁啟動。壓縮機頻繁啟動不利于回油，由于連續(xù)運轉(zhuǎn)時間很短壓縮機就停了，回氣管內(nèi)來不及形成穩(wěn)定的高速氣流，潤滑油就只能留在管路內(nèi)?；赜蜕儆诒加停瑝嚎s機就會缺油。運轉(zhuǎn)時間越短，管線越長，系統(tǒng)越復(fù)雜，回油問題就越突出。</span>

<strong><span style="font-size:14px;">1、制冷劑在風冷式冷水機制冷壓縮機中的變化：</span></strong><span style="font-size:14px;">制冷劑是從風冷式冷水機蒸發(fā)器的末端進入壓縮機的吸氣口，并在制冷壓縮機中完成制冷劑蒸氣壓縮成過熱蒸氣的過程，壓力也是由蒸發(fā)壓力升高到冷凝壓力。由于壓縮機的壓縮過程是瞬間完成的，因此這個時候的制冷劑蒸氣與外界不會發(fā)生熱量交換，我們稱為絕熱壓縮過程。</span> </p> <p> <strong><span style="font-size:14px;">2、制冷劑在風冷式冷水機冷凝器中的變化：</span></strong><span style="font-size:14px;">待過熱蒸氣進入到風冷式冷水機冷凝器后，由于壓力條件沒有變化，因此會先散發(fā)出一部分熱量，使制冷劑過熱蒸氣冷卻成飽和蒸氣。因這個時候仍然處于等溫條件下，故飽和蒸氣會繼續(xù)放出熱量而冷凝并不斷產(chǎn)生飽和液體。冷凝的時間越長，飽和液體就會越多，飽和蒸氣則會減少，**終結(jié)果就是：制冷劑蒸氣全部冷凝為飽和液體。</span> </p> <p> <strong><span style="font-size:14px;">3、制冷劑在風冷式冷水機節(jié)流元件中的變化：</span></strong><span style="font-size:14px;">由于制冷劑全部已經(jīng)成為飽和液體，因此當飽和液體制冷劑流經(jīng)風冷式冷水機的節(jié)流元件時，就會由冷凝壓力降至蒸發(fā)壓力，溫度由冷凝溫度降至蒸發(fā)溫度。由節(jié)流元件出口流出的制冷劑變?yōu)橐后w約占80%、氣體約占20%的兩相混合狀態(tài)，這其中少量蒸氣的產(chǎn)生，是由于壓力下降液體膨脹而出現(xiàn)的閃發(fā)氣體。</span> </p> <p> <br /> </p><p> <span style="font-size:14px;"><strong>小型冷庫制冷設(shè)備分類：</strong></span><strong><span style="font-size:14px;">小型冷庫一般分為室內(nèi)型和室外型兩種。</span></strong> </p> <p> <span style="font-size:14px;">冷庫外的環(huán)境溫度及濕度:溫度為+35℃;相對濕度為80%。</span> </p> <p> <span style="font-size:14px;">冷庫內(nèi)設(shè)定溫度:保鮮冷庫:+5~-5℃;冷藏冷庫:-5~-20℃;低溫冷庫:-25℃ 。</span> </p> <p> <span style="font-size:14px;">進冷庫食品溫度:L級冷庫:+30℃;D級、J級冷庫:+15℃。</span> </p> <p> <span style="font-size:14px;">裝配式冷庫的堆貨有效容積為公稱容積的69%左右,貯存果蔬時再乘以0.8的修正系數(shù)。每天進貨量為冷庫有效容積的8~10%。</span> </p> <p> <span

style="font-size:14px;">小型冷庫的冷藏容量在1000t以下。</span> </p> <p> <strong><span style="font-size:14px;">2、按冷藏設(shè)計溫度分為高溫、中溫、低溫和**溫四大類冷庫：</span></strong> </p> <p> <span style="font-size:14px;">一般高溫冷庫的冷藏設(shè)計溫度在-2℃至+8℃;</span> </p> <p> <span style="font-size:14px;">中溫冷庫的冷藏設(shè)計溫度在-10℃至-23℃;</span> </p> <p> <span style="font-size:14px;">低溫冷庫，溫度一般在-23℃至-30℃;</span>

style="font-size:14px;">制冷設(shè)備中壓縮機的作用：是在制冷劑回路中起壓縮驅(qū)動制冷劑的作用。壓縮機把制冷劑從低壓區(qū)抽取來經(jīng)壓縮后送到高壓區(qū)冷卻凝結(jié)，通過散熱片散發(fā)出熱量到空氣中，制冷劑也從氣態(tài)變成液態(tài)，壓力升高。壓縮機的工作回路中分蒸發(fā)區(qū)(低壓區(qū))和冷凝區(qū)(高壓區(qū))。制冷劑再從高壓區(qū)流向低壓區(qū)，通過毛細管或膨脹閥噴射到蒸發(fā)器中，壓力驟降，液態(tài)制冷劑立即變成氣態(tài)，通過散熱片吸收空氣中大量的熱量。這樣壓縮機不斷工作，就不斷地把低壓區(qū)一端的熱量吸收到制冷劑中再送到高壓區(qū)散發(fā)到空氣中，起到調(diào)節(jié)氣溫的作用。</span>
