Hydrocarbons such as propane (HC290), butane (HC600), isobutene (HC600a) etc. have zero ODP, small GWP, and excellent thermodynamic property, and they are natural substances. So they are good alternatives of Freon refrigerants.

- 碳氫化合物類(lèi)制冷劑如丙烷(HC290)、丁烷(HC600)、異丁烷(HC600a)等ODP值為零,GWP值很小,具有很好的熱力學(xué)特性,且為天然物質(zhì),因此是一種很好的氯氟烴制冷劑替代物。
