Abstract
Provided is a near-azeotropic refrigerant of a ternary mixture CO2/R41/R170, including the following components by mass percentage: 10% to 64% of CO2, 10% to 47% of R41, and 26% to 52% of R170. The near-azeotropic refrigerant has a low global warming potential (GWP) and a low temperature glide, and can still maintain a near-azeotropic effect at −90° C.
Claims5
A near-azeotropic refrigerant of a ternary mixture CO2/R41/R170, consisting of the following components by mass percentage:
- 10% to 40% of CO2, 30% to 47% of R41, and 26% to 52% of R170, wherein the near-azeotropic refrigerant has a temperature glide of less than 0.2° C. at a bubble point temperature of at or below 0° C.
A near-azeotropic refrigerant of a ternary mixture CO2/R41/R170, consisting of the following components by mass percentage:
- 10% to 15% of CO2, 35% to 47% of R41, and 40% to 52% of R170, wherein the near-azeotropic refrigerant has a temperature glide of less than 0.2° C. at a bubble point temperature of at or below 0° C.
