Abstract

The invention provides an environment-friendly mixed refrigeration working fluid and a refrigeration system. In terms of mass percentage, the environment-friendly mixed refrigerant includes: 15-35% of fluoroethane; 41-80% of trifluoropropene; and 1-30% of trifluoromethyl methyl ether. The various components of the environmentally friendly mixed refrigerant of the present application have a synergistic effect, so that the above mixed refrigerant has a lower GWP value, and at the same time, trifluoromethyl methyl ether (RE143a) also has excellent flame retardancy, which belongs to A1 flammability Therefore, the addition of trifluoromethyl methyl ether (RE143a) can weaken the flammability of the environmentally friendly mixed refrigerant, and then become a mixed refrigerant with good safety performance. Using the above mixed refrigerant for refrigeration can obtain a refrigerant similar to that of R134a The volumetric refrigeration capacity and energy efficiency solve the problem of high GWP value of existing refrigerants (R134a).

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an environmentally friendly mixed refrigerant, refrigerant and refrigeration system. Background technique [0002] With the increasing severity of global warming, more and more attention has been paid to environmental protection issues. More than 170 countries around the world have signed the legally binding "Montreal Protocol-Kigali Amendment". The agreement came into effect on January 1, 2019. Therefore, a refrigerant that does not destroy the ozone layer and has a lower GWP value is required to complete the replacement and conversion work and be effectively used in air conditioning systems. [0003] At present, R134a used in automotive air conditioners has good thermal performance, ODP (ozone potential value) is 0, but because its GWP is 1430, it is within the control range of the Kigali Amendment, and phase-out has become an inevitable trend, so looking for Working flu...
