常用制冷剂R134a的特性 时间：2010-02-22 来源：互联网发布评论进入论坛 R134a（SUVA 134a），化学名：1,1,1,2-- 四氟乙烷，分子组成：CH2FCF3，CAS注册号：811-97-2，分子量：102.0，HFC型制冷剂，ODP值为零。R134a 的热力和物理性质，以及其低毒性，使之成为一种非常有效和安全的替代品。HFC-134a可用在目前使用CFC-12（二氯二氟甲烷）的许多领域，包括：汽车空调、家用电器、小型固定制冷设备、超级市场的中温制冷、工商业的制冷机，聚合物发泡，气雾剂产品，以及镁合金保护气体等。 R134a 作为新一代的环保制冷剂，用于替代R12（二氯二氟甲烷），R22，主要应用于汽车空调，冰箱，冷柜，饮水机，除湿机，中央空调(冷水机组)等制冷空调设备中。 用作保护气体：用于镁合金加工上的保护气体。 用于聚合物发泡：聚合物发泡。 用于气雾剂：HFC-134a也可用于那些对毒性和可燃性要求严格的气雾剂中；由于HFC-134a 的低毒和不易燃性，它被研制用于药物吸入剂的载体（即医用气雾剂）。 压缩机生产商通常建议使用多元醇酯POE（Polyol Ester）和聚二醇PAG（Polyalkylene Glycol）（汽车空调）冷冻机油。 HFC-134a的主要物化性质
中温制冷情况下CFC-12和HFC-134a理论性能的对照 膨胀阀的结构和工作原理 1热力膨胀阀的作用： 热力膨胀阀安装在蒸发器入口，常称为膨胀阀，主要作用有两个：1）节流做用：高温高压的液态制冷剂经过膨胀阀的节流孔节流后，成为低温低压的雾状的液压制冷 剂，为制冷剂的蒸发创造条件； 2）控制制冷剂的流量：进入蒸发器的液态制冷剂，经过蒸发器后，制冷剂由液态蒸发为气态，吸收热量，降低车内的温度。膨胀阀控制制冷剂的流量，保证蒸发器的出口完全为气态制冷剂，若流量过大，出口含有液态制冷剂，可能进入压缩机产生液击；若制冷剂流量过小，提前蒸发完毕，造成制冷不足；
