CFC-113.CFC-114和HCFC-22.20世紀(jì)50年代的，開始使用共沸制冷劑。60年代開始使用非共沸制冷劑。空調(diào)工業(yè)從幼小成長為幾十億美元的產(chǎn)業(yè)，使用的都是以上幾種制冷劑。到1963年,這些制冷劑占到整個(gè)有機(jī)氟工業(yè)產(chǎn)量的98%。到1970年代中期，對(duì)臭氧層變薄的關(guān)注浮出水面，CFC族物質(zhì)可能要承擔(dān)部分責(zé)任。這導(dǎo)致了1987年蒙特利爾議定書的通過，議定書要求淘汰CFC和HCFC族。江蘇高效制冷劑要多少錢氨作為制冷劑有刺激性臭味、有毒、可以燃燒和，對(duì)銅及銅合金有腐蝕作用。</p><div

style="text-indent:25px">R142b制冷劑，沸點(diǎn)較高-9.25℃.凝固點(diǎn)-130.8℃較大特點(diǎn)是在很高的冷凝溫度下，冷凝壓力并不高。如80℃時(shí)只有1.35Mpa，因此它適合在熱泵裝置和高環(huán)境溫度下使用。對(duì)大氣臭氧層有微弱的破壞作用，也將在2040年禁用。R134a，沸點(diǎn)-26.5℃，凝固點(diǎn)-101℃，無色，無味，不燃，不爆，但與礦物性潤滑油不相溶，必須采用聚脂類合成油（如聚烯烴乙二醇），與丁腈橡膠不相溶，故密封件須改為聚丁腈橡膠，吸水性較強(qiáng)，易與水反映生成酸，腐蝕管絡(luò)及壓縮機(jī)，對(duì)系統(tǒng)干燥度要求更高，系統(tǒng)中的干燥劑要換成XH-7或XH-9分子篩。壓縮機(jī)電機(jī)線圈絕緣材料必須加強(qiáng)絕緣等級(jí)，是一種不太成熟的制冷劑。</p><p

Perkins）在1834年建造了首臺(tái)實(shí)用機(jī)器。它用做制冷劑，是一種蒸氣壓縮系統(tǒng)。二氧化碳(CO2) 和氨(NH3)分別在1866年和1873年首先被用作制冷劑。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。其應(yīng)用限于工業(yè)過程。制冷劑是制冷機(jī)中完成熱力循環(huán)的工質(zhì)。</p><div style="width:100%;text-align: center;"><img
