R1234ze(E)：這是 R1234ze(Z) 的另一種異構(gòu)體，分子結(jié)構(gòu)略有不同。 與 R1234ze(Z) 的 71 相比，它的 GWP 較低，為 6。它也是一種無毒且輕度易燃的制冷劑，可用于汽車空調(diào)、熱泵和冷水機(jī)等各種應(yīng)用23。

R1233zd(E)：這是一種氫氟烯烴 (HFO) 制冷劑，GWP 極低，低于 11。它也是無毒且不易燃的。 它可用作 R245fa 的低 GWP 替代品，R245fa 用于高溫?zé)岜煤陀袡C(jī)朗肯循環(huán)24。

R1336mzz(Z)：這是另一種 HFO 制冷劑，GWP 低至 91。它也是無毒且不易燃的。 它可以在有機(jī)朗肯循環(huán)應(yīng)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.
