Abstract

一种用于压缩制冷机的新型节能制冷剂，它由丙 烷，丁烷，二氧化碳组成。它与目前广泛使用的制冷 剂氟利昂R12相比较，具有汽化潜热大，冷冻能力强， 沸点低，制冷温度低，分子量小，粘度低，易流动，价格 便宜，易得，不破坏大气臭氧层优点，是一种值得广泛 推广使用的制冷剂。

Description

本发明涉及一种用于压缩制冷机的制冷剂。获得低温称为制冷。制冷方式有压缩式，吸收式，电磁振荡式，半导体式和太阳能式多种。目前使用最多的是压缩式和吸收式，尤以压缩式使用最为广泛。
压缩制冷机是由压缩机，冷凝器，毛细管，蒸发器组成一个封闭的制冷系统，在制冷系统中灌注低沸点的制冷剂，压缩机依靠电动机的动力驱使制冷剂在制冷系统内往复循环，即被压缩机压缩后的高温高压气态制冷剂通过冷凝器散热降温而液化，高压液态制冷剂通过毛细管节流降压流入蒸发器，在蒸发器内。液态制冷剂迅速汽化而吸收外界的热获得低温。低温低压气态制冷剂被压缩机吸入重新压缩，如此循环。
可见，制冷剂的汽化潜热（1Kg制冷剂汽化时从外界吸收的热量）和正常沸点（在lata压力下的沸点）两项物理参数，是选择制冷剂极重要的技术指标：制冷剂的汽化潜热愈大，冷冻能力就愈大，压缩机消耗的功就愈小;制冷剂的正常沸点愈低，制冷温度就愈低。
制冷剂种类很多;（1）、无机化合物类制冷剂如NH3，CG2，（2）、氟利昂制冷剂，这类制冷剂是饱和烃与F，Cl，Gr的衍生物，如R11，R12，R13，R14，R22，（3）、烷烃类制冷剂，如C3H8，C4H10，（4）、链烯烃类制冷剂，如C2H4。
目前，国内外普遍采用氟利昂R12（CF2CI2）作家用压缩制冷机（电冰箱，空调器）的制冷剂，R12具有制冷温度低（R12的正常沸点-29.8℃），不燃，不爆，无毒，化学性较为稳定，不腐蚀金属优点，但R12的汽化潜热很小（39.7千卡/公斤），冷冻能力低，耗电量大;R12的分子量大（120.9），粘度大，不易流动，耗电量大;尤其是R12对大气臭氧层具有破坏作用，这个问题，全世界十分关注，呼声很高。
本发明提供一种制冷剂。它是由丙烷，摩尔分数0.1～0.5;丁烷，摩尔分数0.1～0.7;二氧化碳，摩尔分数0.15～0.8;余量为丙烯，丁烯，甲烷，乙烷，戍烷，硫化氢组成的低沸点组合物。
与氟利昂R12相比较，本发明具有下列优点：
1、对大气臭氧层无破坏作用;
2、R12的正常沸点-29.8℃;本发明中的C3H8正常沸点-42.096℃，异C4H10为-11.72℃，CO2为-78.5℃。因此，本发明制冷温度比R12低：
3、R12的汽化潜热39.7KCal/kg。本发明中的C3H8汽化潜热为107.8kcal/kg;C4E10为87.7kcal/kg;CO2为138.6kcal/kg。本发明的汽化潜热远大于R12，冷冻能力比R12大得很多，是一种节能制冷剂;
4、R12的分子量为120.5，本发明中的每个组份的分子量都比R12小，其加权分子量亦比R12小，本发明粘度小，易流动，节省电力;
5、R12的价格6元/kg，本发明价格约3.5元/kg。
