Description

technical field

[0001] The invention relates to a refrigeration working medium, in particular to an environment-friendly mixed refrigeration working medium, a preparation method and refrigeration equipment. Background technique

[0002] R22 has excellent comprehensive performance and thus has been widely used in the refrigeration industry. However, due to its destructiveness to the ozone layer and high greenhouse effect index, it was included in the phase-out list at the Copenhagen Conference in 1991, followed by the Montreal Protocol. "The 19th Meeting of the Parties decided to accelerate the phase-out of chlorofluorocarbons (HCFCs), which accelerated the process of phase-out of R22. Later, according to the provisions of the Kigali Amendment to the Montreal Protocol, alternative refrigerants for R22 include R410A and R404A. , R407C will be gradually phased out due to the disadvantages of exacerbating the greenhouse effect. Therefore, it is an urgent task for the refrigerati...
