Abstract

Refrigerant blends of HFOs and HCs, having HFOs as the main component, provide better cooling capacity than incumbent HFOs and maintain low flammability. Refrigerant blends of HFOs and HCs, having HCs as the main component, allow for larger HC charge at reduced flammability. Such compositions include (i) at least one compound selected from HFO-1234ze(E), HFO-1234ze(Z), HFO-1336mzz(E), HFO-1336mzz(Z), HCFO-1233zd(E), HCFO-1233zd(Z), CFO-1112, and combinations thereof, (ii) at least one other compound selected from HC-290, HC-1270, R-600, R-600a, R-601, R-601a, R-744, R-717, and combinations thereof, and optionally (iii) at least one other compound selected from HFC-134, HFC-134a, HFC-125, HFC-32, HFC-152a, and combinations thereof. These compositions are useful as refrigerants in air conditioning, heat pumps, refrigeration, and/or chillers.
