Abstract

The invention relates to the technical field of refrigeration, and discloses an environment-friendly energy-saving refrigerant composition as well as a preparation method and application thereof. The refrigerant composition comprises a first component, a second component and a third component, wherein the first component is monofluoromethane, the second component is 1,1,2-trifluoroethylene, and the third component is n-butane, trifluoroiodomethane, dimethyl ether, isobutane, propane, propylene, 2,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene or 1,1-difluoroethane. Based on the temperature slippage characteristic of the non-azeotropic refrigerant, the environment-friendly energy-saving refrigerant composition with low GWP and high system energy efficiency is provided by weighing the respective characteristics of different refrigerants; the refrigerant composition has good environmental performance, and the GWP of the refrigerant composition is lower than 140 while the GWP of most refrigerant compositions is lower than 100; and meanwhile, the refrigerant composition can remarkably improve the operation energy efficiency of refrigeration equipment, and the purpose of saving energy is achieved.

Description

technical field [0001] The present application relates to the technical field of refrigeration, in particular to an environment-friendly and energy-saving refrigerant composition and its preparation method and application. Background technique [0002] As the environmental impact of global warming becomes increasingly serious, the Montreal Protocol Amendment proposes a series of requirements to reduce and phase out the high GWP (Global Warming Potential) refrigerants currently in use. In order to achieve the goal of "carbon neutrality" in 2060, my country has also implemented a strict ecological environment protection system and proposed a number of policies and plans. High-GWP refrigerants are facing strict reduction policies, and it is urgent to find low-GWP refrigerant alternatives. However, while refrigerants meet environmental protection, they also need to meet the energy-saving performance of the refrigeration system, so that the energy efficiency or capacity of the sy...
