Embodiment 1

[0059] Example 1: The two components of propane (R290) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) are physically mixed in a liquid state at a mass percentage of 45:55 , to obtain a high-efficiency and environmentally friendly mixed refrigerant.

[0060] That is, if the total mass of the mixed refrigerant is M, the mass M is multiplied by 45% propane; the mass M is multiplied by 55% trans-1,3,3,3-tetrafluoropropene; these two The components are physically mixed evenly in the liquid state, and the following expressions are analogous.

Embodiment 2

[0061] Example 2: The two components of propane (R290) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) are physically mixed in a liquid state at a mass percentage of 46:54 , to obtain an environmentally friendly mixed refrigerant.

Embodiment 3

[0062] Example 3: The two components of propane (R290) and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) are physically mixed in a liquid state at a mass percentage of 47:53 , to obtain an environmentally friendly mixed refrigerant.

Abstract

The invention discloses an efficient environment-friendly mixed refrigerant, a preparation method and refrigeration equipment, and the efficient environment-friendly mixed refrigerant comprises the following components in percentage by mass: 45-60% of a first component and 40-55% of a second component; the first component is propane, and the second component is trans-1, 3, 3, 3-tetrafluoropropene. The mixed refrigerant is excellent in thermophysical performance, efficient, environmentally friendly, good in cycle performance and safety performance and capable of being used for solving the replacement problem of R22 in the refrigeration air conditioner industry.

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...
