style="text-indent:25px">氨制冷裝置中不能使用銅及銅合金材料，并規(guī)定氨中含水量不應超過0.2%。氨的臨界溫度較高（tkr=132℃），汽化潛熱大，在大氣壓力下為1164KJ/Kg，標準工況下的單位容積制冷量也大，氨壓縮機尺寸可以較小。純氨對潤滑油無不良影響，但有水分時，會降低冷凍油的潤滑作用。氨在潤滑油中不易溶解，故要在裝置中設置油分離器，減少潤滑油進入冷凝器和蒸發(fā)器，防止熱交換表面被油污染后傳熱性能降低，蘇州高效制冷劑有哪些，蘇州高效制冷劑有哪些。純氨對鋼鐵無腐蝕作用，蘇州高效制冷劑有哪些，但當氨中含有水分時將腐蝕銅和銅合金（磷青銅除外），故在氨制冷系統(tǒng)中對管道及閥件均不采用銅和銅合金。制冷劑在南方一些地區(qū)俗稱雪種。蘇州高效制冷劑有哪些</p><div

style="text-indent:25px">在低層大氣中必須十分穩(wěn)定（也就是具有足夠長的大氣壽命），使其能夠達到臭氧層。例如氫氯氟烴雪種HCF22和HCFC123,都有一個氯原子，能消耗臭氧，其大氣壽命分別為 12.1和14年，且氯原子相對活潑，能在低層大氣中發(fā)生分解，到達臭氧層的數(shù)量就不多。因此HCFC22和HCFC123破壞臭氧的能力比CFCs小得多。制冷劑分類：無機化合物、有機化合物、混合工質(zhì)。對空調(diào)行業(yè)規(guī)定了具體淘汰目標，1）工商制冷：2003年停止CFC11/12新灌裝，2010年停止CFC11/12維修補充的再灌裝。2）家電：1999年40%新生產(chǎn)的冰箱冷柜的替代，2003年70%新生產(chǎn)的冰箱冷柜的替代，2005年100% 新生產(chǎn)的冰箱冷柜的替代。3）汽車空調(diào)：2002年停止新生產(chǎn)CFC12空調(diào)，2009年后在汽車空調(diào)上只允許使用回收的CFCs。到目前為止，我國*簽署了倫敦修正案，所以尚沒對HCFCs的淘汰作出承諾。蘇州杜邦制冷劑價錢制冷劑的主要技術指標有飽和蒸氣壓強、比熱、粘度、導熱系數(shù)、表面張力等。</p><div

style="text-indent:25px">消耗臭氧的化合物，除了用于雪種，還被用于氣溶膠推進劑、發(fā)泡劑、電子器件生產(chǎn)過程中的清洗劑。長壽命的含溴化合物，如哈龍（Haion)滅火劑，也對臭氧的消耗起很大作用。氯原子和一氧化氮（NO）都能與臭氧反應，正在世界大量生產(chǎn)和使用CFCs由于制冷劑其化學穩(wěn)定性好（如CFC12的大氣壽命為102年）不易在對流層分解，通過大氣環(huán)流進入臭氧層所在的平流層，在短波紫外線UV-C的照射下，分解出CI 自由基，參與了對臭氧的消耗。歸納起來，要使臭氧發(fā)生消耗，這種物質(zhì)必須具備兩個特征：含氯、溴或另一種相似的原子參與臭氧變氧的化學反應；</p><p style="text-indent:25px">新的解決方案是開發(fā)HFC族，來擔當制冷劑的主要角色。HCFC族作為過渡方案繼續(xù)使用并將逐漸淘汰。在1990年代，全球變暖對地球生命構成了新的威脅。雖然全球變暖的因素很多，但因為空調(diào)和制冷耗能巨大（美國建筑物耗能約占總能耗的1/3），且許多制冷劑本身就是溫室氣體，制冷劑又被列入了討論范圍。雖然ASHRAE標準34把許多物質(zhì)分類為制冷劑，但只有少部分用于商業(yè)空調(diào)。1985年2月英國南極考察隊隊長發(fā)曼（J.Farman)首先報道，從1977年起就發(fā)現(xiàn)南極洲上空的臭氧總量在每年9月下旬開始迅速減少一半左右，形成“臭氧洞”持續(xù)到11月逐漸恢復，引起世界性的震驚。制冷劑需具有良好的化學穩(wěn)定性。</p><div

style="text-indent:25px">制冷劑充入量的準確判斷方法：測重量。在充注氟利昂時,事先準備一個小臺秤，將制冷劑鋼瓶放入一個容器中，再在容器中注入40℃以下的冷水(適用于空調(diào)器的低壓充注制冷劑蒸汽)。充注前記下鋼瓶、溫水及容器的重量，在充注過程中注意觀察指針。當鋼瓶內(nèi)制冷劑的減少量等于所需要的充注量時可停止充注。測工作電流。用鉗型電流表測工作電流，制冷時，環(huán)境溫度35℃，所測得的工作電流與銘牌上電流相對應。溫度越高，電流相應增大，溫度越低電流相應減少。在風機正常、兩器散熱號的情況下按空調(diào)器工況測電流值作比較。制冷劑需較高的傳熱系數(shù)、較低的粘度及較小的密度。蘇州杜邦制冷劑價錢</p><p
