The present application relates to an azeotropic composition of HFO-1234YF and a hydrocarbon. In one embodiment, a refrigerant composition includes 2, 3, 3, 3-tetrafluoropropene (HFO-1234yf) and at least one of ethane (R-170) or propane (R-290), which exhibits near azeotropic or azeotrope-like behavior. The refrigerant composition exhibits a low global warming potential (GWP) and does not deplete ozone. The refrigerant composition may be used as a heating or cooling fluid in a variety of heating or cooling systems, including heat pumps and other heating and cooling circuits, such as in the automotive industry.
本申请涉及HFO‑1234YF和烃的共沸组合物。制冷剂组合物包含2,3,3,3‑四氟丙烯(HFO‑1234yf)以及乙烷(R‑170)或丙烷(R‑290)中的至少一种,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(包括热泵以及其他加热和冷却回路)中用作加热或冷却流体,例如在汽车工业中。
