style="text-indent:25px">目前我國空調(diào)行業(yè)使用較多的制冷劑是HCFC物質(zhì)R22。R290與R22的標(biāo)準(zhǔn)沸點、凝固點、臨界點等基本物理性質(zhì)非常接近，具備替代R22的基本條件。在飽和液態(tài)時，R290的密度比R22小，因此相同容積下R290的灌注量更小，試驗證明相同系統(tǒng)體積下R290的灌注量是R22的43%左右。另外，由于R290的汽化潛熱大約是R22的2倍左右，因此采用R290的制冷系統(tǒng)制冷劑循環(huán)量更小。R290具有良好的材料相容性，與銅、鋼、鑄鐵、潤滑油等均能良好相容。未來我國還將進(jìn)一步加大使用R290制冷劑的空調(diào)產(chǎn)線改造示范試點力度。隨著對R290應(yīng)用技術(shù)研究的不斷深入、使用經(jīng)驗的不斷積累，環(huán)保型制冷劑R290未來將擁有廣闊的市場應(yīng)用前景。其他化學(xué)制品包括化學(xué)氰（石油醚和石腦油）、二氧化硫(R-764)和甲醚，曾被作為蒸氣壓縮用制冷劑。</p><div

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(xué)反應(yīng)；非共沸制冷劑由兩種或兩種以上的制冷劑按一定的比例混合而成。上?；裟犴f爾R407C工廠</p><p

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(yīng)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(biāo)準(zhǔn)工況下的單位容積制冷量也大，氨壓縮機(jī)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(shè)置油分離器，減少潤滑油進(jìn)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。純氨對鋼鐵無腐蝕作用，但當(dāng)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。上?；裟犴f爾R407C工廠</p><p
