摘要： Environmentally friendly refrigerant blends utilizing blends including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and fluoroethane (HFC-161). The blends have ultra-low GWP, low toxicity, and low flammability with low temperature glide or nearly negligible glide for use in a hybrid, mild hybrid, plug-in hybrid, or full electric vehicles for thermal management (transferring heat from one part of the vehicle to the other) of the passenger compartment providing air conditioning (A/C) or heating to the passenger cabin.
