Refrigerant compositions including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and propylene (R-1270) which exhibit near-azeotropic or azeotrope-like behavior. The refrigerant compositions exhibit a low global warming potential (GWP) and are non-ozone depleting. The refrigerant compositions are useful as a heating or cooling fluids in a variety of heating or cooling systems including heat pumps and other heating and cooling loops, in for example the automotive industry.
制冷剂组合物包含2,3,3,3‑四氟丙烯(HFO‑1234yf)和丙烯(R‑1270),其表现出近共沸或类共沸行为。制冷剂组合物表现出低全球变暖潜能值(GWP)并且不损耗臭氧。制冷剂组合物可在多种加热或冷却系统(包括热泵以及其它加热和冷却回路)中用作加热或冷却流体,例如在汽车工业中。
