1. 混合制冷剂设计R513A由50%的HFC-R134a与50%的HFO-R1234yf组成。这种混合比例既保留了HFC的成熟性能，又通过HFO大幅降低全球变暖潜值（GWP）。其GWP约为675，较纯R134a（GWP=1430）降低超过50%，符合欧盟F-gas法规等逐步淘汰高GWP制冷剂的趋势。2. 物理性能与兼容性R513A的沸点（-29.58℃）、临界温度（...

R134a (一)物性特点 R134a(四氟乙烷)是最早得到广泛应用的HFC制冷剂。其ODP为0,GWP=1430,是典型的高GWP值冷媒。R134a无色无味,不燃,无毒,化学性质稳定。其沸点-26.1℃,临界温度101.1℃,饱和蒸汽压与R12相近,易于在原R12系统中替代[3]。R134a的电绝缘性好,可用于冷冻机的马达直接冷却。但其对水具有一定吸湿...
