Abstract
A non-combustible mixed refrigerant having a low greenhouse effect and an application thereof, the mixed refrigerant comprises the following components in mass fractions: 4-31.5% of R125, 50-80% of R1234ze (E) and 12-22% of R1234yf. Under the cooperation of each component dosage range, the mixed refrigerant becomes non-combustible, the ODP is 0, and the GWP is not greater than 1000. The present invention may be used in a refrigeration system, does not destruct ozone, reduces the greenhouse effect, and has a low slip temperature, relating to ternary azeotropic or near-azeotropic refrigerants, and being beneficial for the stable operation of a refrigeration system. The mixed refrigerant may also be used as a foaming agent or an aerosol propellant, and has the advantages of being non-combustible, having a low ozone destruction index, and being environmentally friendly, safe and reliable.
