Problems solved by technology

However, HFC-152a is flammable and can form an explosive mixture when mixed with air, and there is a danger of combustion and explosion when exposed to heat sources and open flames, which limits its use as a refrigerant alone

Abstract

The invention relates to a refrigerant composition of HFC-152a, belonging to the field of refrigerants. The refrigerant composition is characterized by being composed of the following components in percentages by mass: 0.1-3% of HFC-134a, 0.1-60% of HFO-1234yf, 3-45% of CF3I and 0.1-70% of HFC-152a. The invention provides a non-flammable and environmentally-safe matter composition. The refrigerantcomposition provides a product with a low value GWP of less than 150, and meets the requirements of the industry for refrigerant GWP. The refrigerant composition provided by the invention has the characteristics of zero ozone depletion potential value and low global greenhouse effect potential value, and has extremely small influence on the atmosphere and the earth environment.

Description

technical field [0001] The invention relates to a refrigerant composition of HFC-152a, which belongs to the field of refrigerants. Background technique [0002] Halocarbons have been widely used in a variety of industrial applications, including as refrigerants, aerosol propellants, blowing agents, heat transfer media, and gas dielectrics. To date, most of these applications have utilized compositions containing significant amounts of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). However, the use of some of these halogenated hydrocarbons poses environmental concerns. For example, both CFCs and HCFCs tend to have relatively high global warming potentials (GWP). Therefore, there is a need in many applications to use compositions which are acceptable for their intended use, but which at the same time have a lower global warming potential than CFCs and other unfavorable halogenated compounds. [0003] 1,1-Difluoroethane (HFC-152a) has an ozone depleting pot...
