Description

technical field [0001] The invention relates to the technical field of refrigerants, in particular to an environment-friendly ternary non-azeotropic high-condensing temperature refrigerant and a charging method thereof. Background technique [0002] According to the components contained in the refrigerant, it can be divided into 1. Single refrigerant, 2. Mixed refrigerant. A single refrigerant contains only one chemical substance, and its thermophysical performance parameters are constant. For example, R134a, R152a and other refrigerants have High energy efficiency. [0003] A mixed refrigerant is a mixture of two or more refrigerants. According to whether the composition of gas phase and liquid phase is equal when it is in gas-liquid phase equilibrium, it can be divided into: [0004] Azeotropic mixed refrigerant: when the gas-liquid phase is balanced, the gas-liquid two-phase composition is equal to the azeotropic mixed refrigerant (including the near-azeotropic mixed re...
