R1234ze(E)：这是 R1234ze(Z) 的另一种异构体，分子结构略有不同。 与 R1234ze(Z) 的 71 相比，它的 GWP 较低，为 6。它也是一种无毒且轻度易燃的制冷剂，可用于汽车空调、热泵和冷水机等各种应用23。
R1233zd(E)：这是一种氢氟烯烃 (HFO) 制冷剂，GWP 极低，低于 11。它也是无毒且不易燃的。 它可用作 R245fa 的低 GWP 替代品，R245fa 用于高温热泵和有机朗肯循环24。
R1336mzz(Z)：这是另一种 HFO 制冷剂，GWP 低至 91。它也是无毒且不易燃的。 它可以在有机朗肯循环应用中用作 R245fa 的直接替代品14。
R1234ze(E): This is another isomer of R1234ze(Z) with a slightly different molecular structure. It has a lower GWP of 6 compared to R1234ze(Z)'s 71. It is also a non-toxic and mildly flammable refrigerant that can be used in various applications such as car air conditioners, heat pumps, and chillers23.
R1233zd(E): This is a hydrofluoroolefin (HFO) refrigerant with a very low GWP of less than 11. It is also non-toxic and non-flammable. It can be used as a low-GWP alternative to R245fa, which is used in high-temperature heat pumps and organic Rankine cycles24.
R1336mzz(Z): This is another HFO refrigerant with a low GWP of 91. It is also non-toxic and non-flammable. It can be used as a drop-in replacement for R245fa in organic Rankine cycle applications14.
