Description

1,1,1,2-四氟乙烷,1,1,1-三 氟乙烷、和五氟乙烷的非共沸混 合物,及其作为制冷剂的应用
本发明涉及制冷领域,更具体地说,本发明的主题是对环境有很小或没有影响的制冷剂的非共沸混合物,该混合物用于在制冷系统中取代含氯氟烃(CFC或CFHC)。
在用于运输制冷的系统中,系统是按照热力学循环而运行的,该循环一般由能降到-35℃的蒸发温度,在50与70℃之间的冷凝温度,约-5℃的液体冷却和至少10℃的蒸汽过热来限定。
一般用于运输制冷的制冷剂是二氯二氟甲烷和1,1-二氟乙烷的共沸混合物(已知为R-500)。这种混合物,它优选用二氯二氟甲烷,使得有可能获得优良的制冷能力,同时保留合理的压力水平。然而,现已证实,由于它们对臭氧的影响,CFCs和CFHCs,特别是R-500将迟早被对环境有较小破坏的制冷剂取代。
为了在制冷设备中取代R-500,代用品应呈现尽可能与R-500接近的热力学性能,特别是制冷能力和操作压力。另外,出于对产品良好的稳定性和设备耐久性的考虑,要求排出的温度不要超过R-500。最后,代用品应该是非可燃的。
与氯化化合物相比,1,1,1,2-四氟乙烷(FHC-134a),1,1,1-三氟乙烷(FHC-143a)和五氟乙烷(FHC-125)对臭氧没有影响。
尽管FHC-125和-143a具有优良的制冷能力,但它们的主要缺点是它们为高压流体。而且,FHC-143a是一种易燃化合物。
FHC-143a,一种非可燃化合物,是一种具有良好效率的制冷剂,但它的制冷能力太低使它难以用作R-500的代用品。
现已发现一种混合物,它具有与R-500很接近的热力学性能,特别是制冷能力,并且它的蒸汽压不超过R-500的20%以上,按重量计,该混合物含有约55-65%的FHC-134a,10-44%的FHC-125和1-27%的FHC-143a。而且,这些混合物在100℃时是非可燃的。
本发明的混合物因而能用于运输中的制冷系统中。优选使用的混合物含有58-62%的FHC-134a,13-17%的FHC-125,和24-26%的FHC-143a特别优选的混合物含有60%的FHC-134a,15%的FHC-125,和25%的FHC-143a。
下列实施例说明本发明,但并不限制说明。
实施例1
